Human Bitches

Chapter Three: Rewards for Good Girls

By Gideon Kalve Jarvis

The one thing I hate about training is the discipline. Not the discipline I have to use on my clients' bitches; that's just part of the job as normal. It's the discipline it takes to keep myself all pent in all the time. Girl knew better than to touch me while I was asleep (not that I got much sleep, of course), and I knew better than to tempt her. So I woke up on the couch, my hardon stiff enough to poke out the knots in the boards around my junkyard, the scent of Miss Benny and Girl and three truly hot human girls tormenting my senses to the fullest.

There was an advantage, though, to the psychological torture I was putting myself through for the sake of the job: it made it really easy to wake up.

"Urgh," I got out, before pulling on a pair of shorts and a shirt, then stumbling into the kitchen, my eyes still slightly out of focus. Girl wasn't gonna get up at this time of day, no way, no how. Not unless she really had to, and I really, really insisted, which I wouldn't do unless it was important. Early morning exercises, though, didn't rank as important, especially since Girl had already set up everything that she needed the night before.

Breakfast was quick, simple, just a basic egg-based smoothie, lots of protein to it, filling and a little bit chunky in places where the meat Girl had blended up into it the night before hadn't gotten completely ground. That was my normal breakfast, with occasional additions when I needed some extra protein, and it'd always worked well for me, the dollop of honey Girl always added making for a really interesting blend of flavors. Some humans I know, body builder and fighter and military types in my many circles of acquaintances, have tried it, and they all say my daily smoothie tastes nasty. Guess it's just one of those inevitable differences between humans and morphs like me.

Sipping my smoothie, letting it have time to digest a bit between gulps, I wandered over into Girl's equipment room. Girl's always had a knack for audiovisual stuff, and especially recording equipment. She was given military training herself, surveillance and stuff like that, though she never got to use the training before she was shipped off to her sadistic private owner. Not until she ended up with me, anyway. Turns out all her training was perfect for getting my website up and running, complete with video. It's all a bit much for me, since I was more on the heavy lifting and lighter brainwork end of military training during my time, though I do know enough to check the equipment over, make sure it's all working right, and then to turn on the camera feed when I needed it. Girl made it really simple - a sign of genius if I ever knew one - so I don't need to wake her up every time I want to record an early morning workout.

Recording as much of the training process as possible is one of those things I quickly discovered was essential to keeping this sideline business afloat, and for more than one reason, some less serious than others. The first and most obvious use for the video feeds I collect is to review them for kinesthetic motion, to figure out what either I or my trainee is doing wrong. I know what to look for, having been an assistant trainer (the highest training rank a morph could attain in the military) after finishing my stint on active duty. That, and it's something they used on us enlisted morphs all the time, keeping cameras trained to see not only if our physical performance was improving, but our attitudes as well. Being caught on camera flipping off a human officer was an easy way to end up in remedial training - the nasty kind.

Of course, that mental training is still important, especially with us morphs. After all, we're a strange hybrid of mentalities, somewhere between creatures of reason like humans, and creatures of instinct like the animals that we most resemble. It's a twisted mix, really, and sometimes it's too much for us, especially when we're under extended periods of stress. I've seen morphs in combat just totally lose it, going into full-on fight-or-flight mode, as made sense under the circumstances. For the herbivores, this usually meant that they would vanish at the first opportunity. For the carnivores...well...let's just say it was best to just hope that they focused their attention on the enemy rather than on you. Had a lupomorph, a brute bred for his feral nature, suddenly just totally lose it on me once in a combat situation. I was just lucky that he identified me as a part of his "pack," and the enemy shooting at us as prey. Still, I had to put him down afterward. He'd tasted human blood, and lots of it, you get me, and if I hadn't done it fast and neat in the field, a quick bullet through the back of the head, the military machine would've done it if we ever got back to base, and probably a whole lot worse, putting him through their psych grinders before they finally got around to the euthanasia part. There're some stressors beyond which the mind of a morph just can't cope any more, and handling that divide between killing humans in the line of duty and preserving human life is one of the big ones. Lost a lot of good friends who just couldn't cope after being put into active duty. Me, I handled it, and a lot more of us did than didn't; we were just that well made. But it was still heartbreaking to have to be the one to put down one of the five percent who just couldn't hack it, especially when they were like family, as we all were.

So, yeah, mental training is about as important as physical training for morphs, maybe even more so considering how physically fit we all are by genetics, and video's usually the best way to gather the information on how to fix what problems show up on all fronts. That's all just a long way of saying that I had a camera trained on Miss Benny all night long. Not wanting to mess with her circulation, I'd left her, naked except for a few minor details, untied in her kennel. The kennel for most morphs is six feet square on all sides. Tiny place, enough to make a human claustrophobic pretty fast, but kind of comforting for the beast bits of our brains, which tends to think of the closed space as a sort of den or second womb. As long as the lights're dim, that is, and the temperature is just a bit uncomfortably warm for a human, which I naturally made sure it was for Benny.

Glancing at the screen, a single red light bulb the only illumination in the kennel, I couldn't help but smirk as I saw that I wasn't the only one who'd had a rough night. There was Miss Benny, whimpering, doing her best to try and start a fire between her cream-furred thighs. Of course, she wasn't having a whole lot of success at this effort, mostly because, before I'd tucked her in for the night, I'd made sure that her hands were covered in a pair of mitts. They were kinda close to oven mitts, actually, but a little more form-fitting, with the thumb bound against the rest of the fingers. They tended to make a morph's hands look like paws rather than hands, and effectively removed the majority of the wearer's manual dexterity. I'd worn them as a punishment during my service, and as a part of discipline training, and knew how frustrating it could be to suddenly have paws that were about as effective for jacking off as those of a four-legged dog's. That is to say, not at all. It pleased the efficiency-minded part of my brain to see that the mitts worked just as well for females, as it seemed they were a bit too soft for Benny to get any proper purchase, besides being too unwieldy for any sort of penetration at all. The light gag and muzzle I'd had her wearing seemed to have done its job keeping her from using her muzzle on herself as well.

Focus, though. This isn't about me, or even really about her. This is all about satisfying Miss Benny's owner, the still-unseen mistress, Mrs. McMichaels. If it was about our satisfaction, I'd have buried my bone in Benny for most of the night, and probably had Girl helping me.

Getting a metal bowl and pouring out a decent helping of smoothie into it, I soon headed into the back where the kennels were located, connected to the main shack by an aging metal security door. Before I'd renovated it, the kennels had been a large garage area for storing trucks when not in use. I still couldn't get over how much of a mess the place had been before I decided to renovate it some. Add in some interior walls and a few supporting beams, then move in a few pieces of exercise equipment and some barred doors, and bam, easy-to-assemble training and sleeping area. Since I only had one tenant of the area at this point, I just ambled over, setting the bowl filled with breakfast smoothie inside the dim interior of the kennel. In the dim red light, I could make out Miss Benny as she faced away from me, whimpering softly as she did her very best to relieve her heat, with little success. Her eyes looked at me as her ears turned in my direction, nostrils flaring at the end of her slim, pretty muzzle, looking pretty cute, really, with her mouth stuffed full of gag. I had to admit: Miss Benny was a real looker, as purebred as they came. But that show of outward aristocracy ended the moment her eyes drifted a little lower, to the bulge in the front of my training shorts. Immediately her front quarters lowered, her hindquarters lifting, tail moving to the side, revealing her swollen red slit. Benny was way past the point where she was pink down there. This was a bitch that needed some relief, and bad, or so her body'd decided. But then, that was the point of this training: to put aside what the body and its instincts said you were supposed to do, and instead do as you were told by your master. In this case, "master" was me. If I did my job right, however, the position would extend just as easily to Mrs. McMichaels and her daughter, Rachael, or anyone else that they designated for the job. It was obvious, of course, that Miss Benny hadn't ever been a military or government bitchmorph, even if she'd had somebody train her as a dogservant and bodyguard in the past. If she had been, they would've made sure that they'd trained her out of these spoiled behaviors really early on, rather than just giving her the basic training for her job and leaving it at that - real shortchange sort of work, actually; shoddy. It's only when morphs weren't trained, weren't taught how to handle their instincts and impulses, that they tended to end up like Miss Benny, too full of herself to listen properly to the ones that she was supposed to protect, too sure that she was a superior creature to humanity to do her job right. It's a harsh way to do things, but it's just the way we canomorphs are. Anybody who wants to judge me had better be a morph too, or else I can call bull.

"That's only for good girls," I said with a snort as I opened the kennel door and delivered a hard, swift slap to Benny's presented rump, making sure to get my palm right in the middle of her wet, juicy cunt. The high-pitched yelp! this brought was as close to satisfaction as I could feel right now. After all, while Benny was able to escape to the kennel at the end of the training day, where her own scent was the only serious distraction, my senses were still aflame with the scents of five healthy females that my instincts constantly told me were in need of a good, stiff breeding. "C'mon, get up, get dressed, get breakfast, and get out here with me," I ordered, putting the bowl of breakfast smoothie down on the floor, undoing and removing her muzzle and gag, and stepping out, closing the door behind me to make sure the rough colliemorph didn't get out of her pen until she'd done as I asked, and was presentable for human society. In all honesty, getting dressed at all was just for sake of formality. After all, it was a lot easier to get a view of kinesthetics when subjects exercised in the buff, so we'd both be stripping down in short order once we got out to the track. Mornings, after all, were for cardio. Still, it's a ritual, and rituals are really important in any sort of behavioral training.

*

It was a morning ritual, a daily regime that kept her in top condition. Bird Phelps (Bridgette by birth, but she hated her full name with all the passion that a teenager could muster) was an athlete at her school, one of the players on the soccer team. Her lean, sleek-muscled build came from her constant efforts to improve herself, her concern about her diet, her exercise, everything. Up until then, she'd gotten some help from her school's coach, but in all honesty, the coach wasn't especially good, her plump, rapidly-aging body showing her abilities clearly. Now Bird was being offered some professional training. Something about the way that Spike carried himself, about his manner and the way he talked told her that the big dog knew just what he was doing. And sure, it had a lot to do with his body, sculpted with truly expert care into an almost mechanical powerhouse. Bird did her best not to picture all of that beautiful male body like she'd seen it yesterday, in the flesh, as she jogged. Those sorts of thoughts just made it harder to focus, and that meant it was harder to keep up the pace she'd set for herself.

It was only a ten minute jog, actually, to the junkyard from the Phelps home. Bird's family were pretty much all used to their oldest daughter's obsession, and there wasn't anybody awake to bother her with awkward questions about her destination. Really, she wasn't quite sure why she was so self-conscious about those sorts of questions. After all, it wasn't like she was going to get into any trouble. Spike wasn't even a human! Sure, he was hung like a porn star, and didn't seem to care if he was seen in the nude, or mind if he was watched doing...well...anything. That didn't mean Bird was focused on anything dirty. This was all about exercise. That was her story, at least the one she was telling herself, and she was sticking to it.

Reaching the sliding metal doors at the front of the junkyard, Bird started to look around for the big red button that was supposed to call inside and let Spike know he had visitors. She'd said she'd come, after all, so Bird expected that Spike would be waiting for her. In her quick search, however, she frowned, hearing the sounds of metal clanking against metal, and then a loud yelp of startled pain, followed by a soft, needy whimper, just like the ones that Rachael's Miss Benny had made yesterday...

No! Not going into those thoughts! Bird forced herself to focus. Turning, she followed the sounds, and soon reached a tall wooden fence, which she discovered separated the junkyard from a smaller lot, surrounded by wooden boards on all sides. Hopping up to grab hold of the top of the fence, Bird took a peek over to see what was going on.

On the other side of the fence, Bird immediately saw that Spike hadn't wasted his time at the junkyard. Instead of what she'd figured would be some empty lot, maybe a place for dumping leftover parts and such, Spike had built a decently-kept outdoor dirt track, complete with benches along one side, and various workout equipment along the track, obviously as part of a military-style fitness course.

Bent over the benches, panting heavily, was Miss Benny, looking over her shoulder with a soft, whining whimper that Bird could hear clearly now that she was peeking over the top of the fence. She had weird mitten-things on her hands, and seemed quite determined to try and get Spike's attention, like any desperately needy bitch in heat probably would in her circumstances, though she made it at least half-look as though she were just stretching out, getting herself warmed up for the workout. She was wearing a pair of jogging shorts and a t-shirt, but it was pretty obvious there was nothing on underneath them, her hard nipples clearly visible like thumbtacks through the thing cotton material of the shirt.

Spike, meanwhile, was pointedly ignoring this obvious invitation, even though he wasn't dressed in anything more covering than Miss Benny - really, just the male equivalent of that tight grey cloth. Instead, he was making a few modifications to a series of odd metal posts, each with a black glass domed top. Satisfied, he nodded at his work, and then turned back to Miss Benny, obviously about to start something...when his eyes immediately lifted to look straight at Bird's.

*

Huh, she actually showed up. I had to admit, right off, I was impressed with the Phelps girl. It's one thing for a human teenager to make a promise to do something. It's quite another for that teenager to actually make good on the promise. That thought made my docked stub of a tail wag despite myself: I liked it when people were "good," or obeyed the rules. Part of being a canomorph. If I were a felimorph, I'm sure I'd have a different set of reactions.

"C'mon over, Miss Phelps," I called out to her, and she lightly vaulted over the fence, graceful as a deer, landing with perfect form on the soft dirt beyond. "We were just about to get started."

To put emphasis on this, I gave Miss Benny's rump another smack, the third that morning, giving a snort of annoyance as I did so. This time, though, she rose to a proper standing position, her head down, looking contrite.

"I'm sorry, master," she said softly, meekly. "I know I've been bad. It's just so hard to control myself right now. And you didn't say I couldn't try to arouse you, after all."

"Well, we'll see how well you handle it with your mitts off," I said, one ear turned to listen to the Phelps girl's approach as I loosened the locks on the mitts, and then slid them off, tossing them onto the bench. "All right, now strip down for the cameras. I'm gonna want some shots of how you move during this workout if I'm gonna get your routine down right."

"Yes master," Benny said without hesitation, and immediately stripped off her t-shirt, followed by the shorts, though she did make sure to deliberately wiggle her fine, toned tush at me as this last bit of clothing came off. "Will I get a reward if I'm good?"

"Heh," I chuckled as I pulled my own shirt up over my head, barely registering the Phelps girl's soft gasp as she realized what was about to happen. "If you can prove you deserve it. I'll probably give you a little bit of a break at the end, to give you some relief. If you stay good all day, until your young mistress shows up, and then stay good with her here, then I'll let you get some proper release."

"Yes master!"

Shoving my shorts down, I turned to Miss Phelps, giving her a grin as I heard Miss Benny eagerly moving to her place on the starting line. I kicked them away, and couldn't help but put my hands on my hips as I saw the ponytailed blonde's eyes taking me all in. If this fine little hottie wasn't a human, I'd...no, best not to even go there. Don't even start the thoughts that go into temptation. I'd lose control. I was designed to be an alpha male, and if I lost control around a human femme as sweet and fine as this one, her body toned, her legs so long and smooth, her breasts just the right size for my hands and my muzzle...rrr! Maybe I should have jacked myself off this morning after all. Sure, Benny would've smelled it, would've known I wasn't holding to the same discipline I was making her going through, but still, it wouldn't just been one thing. And I'm the master figure, after all - I'm supposed to be allowed to do things like that.

But no, that's just not how it works. With a slight tensing of my jaw and of my lower parts, around my sheath, I kept myself tucked in, though I couldn't stop the swelling outward. I think she might've noticed it, judging from the way her eyes got as big as they did (pretty eyes, too, a sort of blue you could just lose yourself in), so I turned away, and pointed down the track at the different stations.

"I've just set up a light one this time around," I told her. "Basic run-through, to get Miss Benny and you used to things. More to let me see what you can do, and plan later stuff from that. The track's set up for four rounds a mile, and we'll be running two miles, so eight laps. You'll do one station per lap." I pointed around the track, standing close to Miss Phelps, just slightly behind her, my arm stretched out next to her head, so I knew her eyes were following my hand and not straying into dangerous territory. "Twenty crunches; ten leg-lifts; ten push-ups; five pull-ups; twenty jumping jacks; thirty-second squat; rope climb; hurdles; and a last added lap for cooldown, just slow jogging. You think you got all that?"

"Y-yeah," she answered back, before she seemed to get control of herself. "But, uh, do I have to do it naked?"

She asked the question with that little chuckle that said, without words, of course she wasn't serious about it, ha ha, just laugh the whole silly thing off. It also added the under-undercurrent of a deep interest in my answer to the question. So...I was honest with her.

"The clothes come off in this sort of test, Miss Phelps, 'cause it's easier for me to see things," I explained with the same sort of grin she had, not putting any pressure on for either side, just laying it out, letting her make her own choice. "Clothes really cover up more'n you'd think. They're usually made to do just that, hiding those imperfections we all want to keep others from seeing, while only showing off the best of us. Well, in this," I waved my hand over the field, "that's just stupid. You're here to get appraised so you can get better. The ancient Greeks did their stuff in the nude for just that reason: the judges at their contests could tell right away who was the better athlete."

"So, why are you naked, then?" she asked next, getting right to the point - and her eyes glancing downward involuntarily, bobbing to my sheath before she caught herself and made them pop right back up to my face again.

"Relax," I told her, chuckling as I reached out and stroked her head gently, almost like scratching an overeager puppy, then took a step back so she could see all of me, and feeling as well as smelling her at once relax and tense up in an entirely different way as I gave her my permission to look at my entire body. "I'm naked too because I'm measuring my own performance also. What kinda teacher would I be if I didn't take every chance to improve myself?"

"I...I guess that makes sense," said Miss Phelps after some thought, her cheeks getting awfully red in the process. I could tell right off that she wasn't used to talks about the birds and the bees. She probably hadn't ever seen adults naked, not in real life anyway. Not surprising, of course, considering the state of the world as it was. It wasn't like she was going to have much chance for play with boys her age.

What happened next, though, kind of caught me off guard, though not completely. I mean, I'd had it in my head as one of those possibilities, and I'd worked out what I would do if it happened, as a backup plan. But when Miss Phelps started to peel off her t-shirt and the sports bra underneath, letting her fine, nicely-shaped breasts pop free of their confines, I lost myself for a moment, and just stared. Thankfully I got over it by the time she got her sports bra over her head, and just walked over, taking her clothes as they came off with a grunt and nod of approval.

"You've got some pretty strong abs, there Miss Phelps," I said, reaching out and giving her tight tummy a pat with my hand, a little surprised at how small she was in comparison to the size of my palm, and how very pale and sensitive her skin seemed to be. It must be genetic, her not tanning so easily.

"Thanks," she said, giggling a bit, before she quickly shoved her shorts down, along with her panties, and kicked them off, just like I'd done only minutes before. "And call me Bird. All my friends do."

"Fair enough," I said, getting the underlying message here: I was her friend, and she was trusting me not to take advantage of her. "Head on over and get into starting position. I'll be there as soon as I get these clothes put up."

Dropping the clothes on the wide wooden bench on the side of the track, I turned to head back to the starting line, and promptly had to renew my focus, my teeth gritting as I worked my brain as hard as I could, all just to keep the nonthinking parts between my legs from taking over. There were Benny and Bird, bottoms up, heads down, in the proper starting position, mostly. I say mostly because the females' butts were really hiked just a little more than was necessary. As I neared the pair, my ears picked up the soft murmur of Benny as she spoke to the human hottie next to her, apparently trying to keep her voice down enough that I wouldn't notice her corrupting my student.

"Now wiggle just a little bit, like you're about to take a swing in golf. That'll get you settled into your spot. Really makes the boys stare, too," the naughty bitchmorph added with a light giggle, which Bird shared, starting to relax and get into the spirit of it, both femmes' eyes risking a quick, surreptitious peek in my direction, just to see if I really was looking (I was, of course). I probably would have said something, but it wasn't necessarily a bad thing, and Bird did seem to be getting past that initial embarrassment at being naked. Not that she had anything to be really ashamed of, of course: the girl was trim, not much excess fat on her, making it pretty easy to follow the lines of her sleek, toned muscled. Her tush was especially well-formed, rounded in the right places, but obviously tight and toned as it tensed up while she got ready to start her run. Add in how her legs had that lean, slender muscle that comes from running a lot, coupled with just a bit of muscle where she must do some weights, and I had to say that Bird's lower body was her best feature. I guess most girls must want a guy to say that they've got a cute face, but if a girl's got hot legs and a sweet butt, there's no denying where my eyes are gonna go.

"All right, this is a test," I said, settling down and digging my toes into the dirt of the track as well, bending down much like they were as I settled into position, catching glances from Bird down between my legs, her blue eyes wide at the sight of my danglies, while Benny was staring at the same thing, her expression one of unabashed lust. "That means you're gonna try to finish it as fast as you can. Since it's both of your first times at this, though, you should probably watch me and stick with my pace so you know what to do at each station. I plan to reach the stations first so you can see what to do next, and linger a little behind on most of the running to keep you going at a nice pace. Got it?"

They nodded, their bodies tensing up in anticipation, their faces going forward, their expressions turning serious as they focused on the task at hand.

"On three. One...two...three!"

*

The moment Spike said "three," Bird gave a short, startled cry as her body was suddenly propelled forward, not just by her own forward thrust, but also from the hand of the big dog coming down on her uplifted rump, the bottom part of his palm catching her slit, left exposed by the extra lift Benny had told Bird to put into her stance. She hadn't really thought about how strong he really was until that moment, as he rushed forward with incredible speed, his hands gripping Bird's and Benny's bottoms firmly as he propelled them right up in front of him with such ease, as though they weighed next to nothing.

It was hard to focus on that first lap, hard to keep her mind on the goal of making it all the way around the track and then up to the first station. Even though Spike's huge hand quickly left her butt after he'd pushed her in front of him, Bird could still feel the imprint of his paw, making her feel as though her butt were glowing, somehow, like a firefly's. The body memory of that touch sent a strange, tingling warmth through her that the pace of running could only partially blot out, a warmth that soon settled into the pit of her stomach. Then, at three-fourths of the lap, Spike picked up his speed and came up right in front of Bird, letting her watch his perfectly-toned body move, his heavy sac bouncing between his legs as he easily made it to the mats on the side of the track well before either Bird or Benny, and dropped to his back, starting to do crunches. Bird heard Benny whine softly, and admitted, as she reached the station and fell to her back as well, she knew how the collie felt, seeing that gorgeous, naked male laid out before her, totally exposed. She wanted to just reach out and touch him, to do...something with him. Sadly, Bird hadn't had the best sex education, prudishness being on the rise at that time, especially in the school system, and she felt the lack of knowledge on the subject keenly as she tried to fill in the missing gap in her fantasies, but failed. It was frustrating! The human porn she'd seen with her friends was so different from the savage, bestial passion of yesterday's coupling between Spike and Benny, but it was all that Bird had to draw on as she tried to imagine herself in the place of one of those stars of the internet's redlight district, and Spike in the male lead.

Bird almost forgot what she was doing, and had certainly lost count of her crunches, when suddenly Spike grabbed her thigh and pushed down, bringing her to a sitting position. This new position had Bird staring straight at Spike's swollen sheath, her breath catching in her throat as she realized she was looking right at the plump head of his penis, peeking out at her from the top of the white, furry tube. It looked surprisingly human, she realized in that snap-second way that comes when one's mind isn't quite focused, like a circumcised human glans, except a slightly lighter pink color, and it looked as though the shaft beneath were all the same color as the head. There was only a short hop of thought from that for Bird to realize from there that Spike had been able to look straight down at her shaved-bare pussy when he'd finished his own crunches!

"Up and at 'em, Bird," Spike said with a chuckle, offering the teen his hand, which Bird took, letting him lift her as though she was nothing. Turning, Bird saw that Benny was already well down the track, and she started after the colliemorph like a shot, determined not to be left behind.

The leg lifts at the end of the second lap involved gripping some handles while resting your arms on a raised platform to support your upper body, while lifting your legs straight up and out in front of you. This was hard enough on Bird that she forgot for a short while all the pubescent tensions that were building up inside of her, enough that she was able to finish before Benny, dropping to the ground and getting back on the track just as the rough collie was just finishing up. By the time Bird had hit the pushup station, however, Benny caught up to her, showing a greater degree of upper body strength than Bird, who'd put most of her attention into her legs, as was natural for a soccer player. While Bird had done enough pushups in the past to keep her chest reasonably toned, her plump breasts angled slightly outward from her chest from the muscle beneath, so that she could do the exercise without too much fatigue, it was still a strain and took her more time than Benny seemed to need. Both femmes were slowed, however, as they were distracted by watching Spike's dangling bits bob while he completed his pushups at a phenomenal pace.

Upper body strength proved to be a big challenge for Bird once again as she finished the fourth lap, only to look in dismay up at the chin-up bar waiting for her. Pull-ups! Why did it have to be pull-ups? The bar was quite wide, and was set sturdily into two high concrete posts, obviously intended to hold a great deal of weight from several people working out at the same time, and when Bird saw Benny hop up to grab onto the bar on Spike's right, Bird couldn't help but do the same on his left, closing her eyes as she put all her concentration into this.

Ngh!

NGH!

Knowing her face must be six shades of red from the effort she was putting into it, her legs kicking in the air as she dropped down from her second, and tried, in vain, to lift herself to do a third, Bird realized with a sinking sensation that, no matter what she did, she wasn't going to be able to do the other three pull-ups. Squeezing her legs together, however, Bird determined she wasn't going to give up without truly giving it her all, and started to lift her legs upward, trying against all odds to get some extra leverage, to somehow push against the empty air.

At that moment, just when Bird was putting her all into lifting herself up, she suddenly felt a massive, familiar paw close on her buns. The strong fingers gripped her, conforming to the curve of her buttock, even as she felt the thick index finger sink into the folds of her vagina, wedging itself quite firmly against her most private place. Bird almost let go of the bar from the initial shock of this unexpected grip, and was even more shocked from the feeling of the fingertip against her hooded clitoris, her every slight movement and thrust of her hips and legs making that sensitive protrusion rub right against Spike's finger. But she didn't have long to muse on this as, with a soft grunt of minor exertion, Spike did another pull-up, lifting Bird right along with him, taking his time as he did it, making her do as much of the work as she possibly could. Never mind that she could feel herself getting truly...gooey down there; Bird knew help when she got it, and did all in her power to take full advantage of Spike's good deed, lifting herself up with all her flagging might.

"Five!" Bird grunted as she dropped to the ground, panting hard (and not completely from exertion), her smooth body glistening with a light sheen of sweat.

"Good job," said Benny with a bright grin and wag of her tail, indicating her sincerity in the compliment. The collie had been nearby, jogging in place to keep from losing her drive, her generous breasts bouncing in ways that Bird hadn't noticed before. Actually, everything seemed more charged than it had, her senses totally on-edge, the human girl's body ready almost to burst into flames or something.

"Yeah," Spike agreed, patting Bird on the back, gently nudging her back towards the track, while she allowed him to do so, fighting past the shiver his touch brought to her whole body. "Good job. Now c'mon: just four more laps."

Jumping jacks, the next station, were easy compared to what Bird had done before, and feeling like she did, she breezed through them, hardly even feeling the exertion. The only thing she felt right then that mattered, as far as she was concerned, was the steadily increasing warmth in the pit of her stomach, and the sensation of wetness between her legs, which just grew as she realized just spread out and exposed each jumping jack left her. Was Spike watching her? Much as she wanted to look, she didn't dare. But she hoped he was. With a lusty, illicit thrill, Bird realized that she wanted that big, beautiful male animal to lust after her the way she was lusting after him. Even after reading those pamphlets and websites Rachael kept finding on human/morph relations, even after all the talks she'd had with her friends on the subject, even with her own interest in the morph rights movement, the thought of actually let a morph...mate with her (if that was the right term) had never really occurred to Bird before that moment. Now it was there, however, and once it had taken root, it dug in deep and started to swell quickly until it was dominating most of Bird's thoughts.

Sixth lap ended, Bird's body starting to feel the fatigue as much as her rising, more instinctual needs, she watched as Spike, reaching the station before her, lowered himself, bending his legs until they were almost at a right angle to the ground, and then hold that position. His back to the track, Bird took this as an opportunity to check out the pit bull's cute buns. Daring to risk it, as she passed him on her way to her own place at the station, Bird brushed her hand over one tight cheek, giving it a quick squeeze, feeling the taut muscle beneath that short, well-groomed white fur.

Hoping against hope that Spike hadn't noticed, Bird lowered herself as far as she dared, and then fixed herself there, her jaw tightening as she started to count off to herself the long seconds before she could continue her run. Thankfully, soccer had kept her legs in great shape, and the thirty seconds passed faster than Bird had thought they would. Faster than she wanted them to, actually, as she'd placed herself deliberately in front of Spike and slightly to the side, knowing this would make it easy for him to look at her naked, vulnerable body. After all, he was in incredible shape, not even panting yet, while she was bathed in sweat from the workout. If he wanted, it wouldn't be hard for him to overpower her, and then to use her like Bird had once seen a pack of lust-crazed male dogs, the four-legged sort, use a poor little bitch they'd caught after she'd tried to run, only to end up surrounded and then gang-raped by those brutish males for hours afterward. At least, Bird might have called it rape, except, before too long, the bitch stopped yelping and struggling as she was skewered by the thick penis spreading her open, and started to join in, moving herself to make it easier for the next dog to have his way with her, and the next, and the next. Looking over at the thought of bitches in heat, Bird saw that Benny was in almost the same position as she was, in front of Spike and slightly to the side, except that Benny was bent over a little more, her tail turned to the side, showing off a hint of her cream-furred cunny. Benny caught the movement of Bird's head, slight though it had been, and grinned at the human girl, winking as she panted, before bending over a little bit more, almost enough to rest her elbows on her thighs. Taking the cue, Bird did the same, thrusting her bottom back invitingly, knowing that, seen from behind, they must make quite a pair of proper, needy bitches, even as she was half-fearfully expecting at any moment to feel two strong paws grip her hips, before...whatever came next happened. Certainly Bird had seen enough porn to know where a penis went, but how it would actually feel when a real, live male had her...that was worlds beyond her present knowledge.

Nothing happened, though. Bird almost whimpered like she'd heard Benny do before at the weight of her disappointment before she started running again.

At the rope climb, there were several knotted ropes bolted securely into an overhanging metal crossbar, and Spike hit his with a leap that took him two feet off the ground, grabbing the rope and starting to clamber up with ease, using just his arms to pull himself upward. As the force of his jump had set the rope to swinging, however, Bird caught sight of brief flashes of pink as Spike turned around and around as he climbed up. It seemed that the display she and Benny had put on before had an effect after all: despite all his efforts to the contrary, Spike was sporting several good, hard inches of thick, juicy erection. Even knowing that this was a timed test, and even though neither of them wanted to disappoint Spike, Bird and Benny both paused at the bottom of the rope, looking up at Spike, Bird's cheeks flushed, Benny openly drooling.

"Let's go," said Benny finally, breaking Bird out of her voyeuristic reverie with a light pat on the back. "He's coming back down. If he caught us staring instead of climbing, he'd bend us both over for a spanking for sure." Benny shivered as she grabbed onto the rope and hoisted herself up. "And believe me: there's nothing more frustrating than a good spanking where you don't get to cum."

Not used to such frank language, and also caught up by the mental image of herself bent over Spike's knee, Bird paused a moment longer, blushing a bit harder still, but quickly shook it off, starting up after Benny. She had to go fairly slow after her trouble with the pull-up bar, but with the knots in the rope to give her good grip, and using her legs as well, Bird made fairly good time. The only disadvantage, of course, to the rope climb was how the rope kept squeezing between her legs as she gripped it against her body. It must be soaked through! Risking a glance down, Bird caught sight of Spike, staring up at them both - yes, both! - and shivered all over as she saw him licking his chops, as though he were looking over two especially choice, bloody steaks he intended to messily devour.

Minutes later, Bird's sneakered feet hit the dirt of the track once more, her whole body feeling as though it were quivering with erotic energy. This time she didn't hold back, putting her all into it as she took off, outpacing Benny, despite the physical ability the colliemorph's tailored genes were supposed to give her. She still didn't catch up with Spike, but she was able to get close enough to watch his naked body move as he raced for the hurdles, and then started to leap over them, one by one, the slight awkwardness of the movement showing how his thick, powerfully-muscled legs were obviously not designed for this sort of activity, built more for stability than jumping power, while training and hard work overcame genes in the end. Bird hit the hurdles head-on as well, her face set in determination as she used her built-up momentum and frustrated need to make each leap, brushing the top of two of them with her running shoes, making them wobble slightly, but not knocking any down. Slowing for her cooldown jog, Bird heard Benny grunting with exertion as she passed the hurdles as well, and before too long she caught up with Bird, then slowed so that they were running side by side. Spike also slowed, and soon all three jogged the final lap, coming to a stop not far from the hurdles, also not far from where they'd started.

"Good workout," Spike said with a praising grin, patting the two femmes on their backs before he started towards where he'd set their clothes on the bench. "I think we can all catch a shower, then get set for the rest of the day."

"But...but what about my reward?" Benny whined plaintively. "You said if I was good I'd get a reward, master."

Bird stood silently, watching, hardly daring to breathe. Whatever happened next, she wanted to see it all.

*

This had to be the absolute worst time and place for Benny to start whining about her reward for being good. I hadn't meant to touch Bird the way I had; my hand slipped when I reached down to give her some help on those pull-ups (though, I admit, leaving it there was entirely my fault). Certainly, I hadn't meant to smell her like I did - like I was doing right then! - as her smooth-shaved young body got hotter and wetter with her rising arousal. But I'd done both, and it had started something inside of me, started to eat at the barrier that kept my instincts from including human females in the same grouping as females of the many breeds of morph. Benny's heatsmell was bad enough, but adding Bird's scent into the mix was an almost unbearable torture. Despite my efforts to stay calm, I grit my teeth, the hackles on my shoulders and back starting to rise. After the tease those two...bitches...had put me through, what I needed most was a chance to soak my balls in ice water. I felt ready to explode, my cock popping like a firecracker!

But...Benny had been good, hadn't she?

I turned, looking at the colliemorph as she looked at me with those big, plaintive brown eyes of hers.

"Go bend over," I said, motioning to one of the nearby hurdles.

"Thank you, master!" Benny exclaimed, and I couldn't help but watch her tail wag as she raced to the hurdle, bending over at the waist to grab its top, spreading her legs wide as she looked over at me, full of hope and expectation. With a growl I approached, one hand seizing her hip, while the other gripped the longer fur of her ruff. Pulling hard on that loose flap of skin at the scruff, I grinned as Benny's legs suddenly went weak, a leftover reaction from our canid ancestry at being held firmly in the mating grip. The hand on her hip slip back and in, and I snorted in amusement at how eagerly the hot little slut that Benny had become thrust back at my hand.

"Just a few orgasms for now," I growled, my hand starting to rug against Benny's fur-framed slit, fingers skirting her clitoris for the time being, avoiding direct contact. "Enough to take the edge off. You'll get your tailhole stuffed later, when your younger mistress comes over to watch you get bred again."

For a moment Benny turned her head, looking back at me. I think she sensed something about the way I phrased my promises of her future pleasures, something that implied there would be more to it than a simple rump-humping. But then my fingers found her clitty and started to rub against it in tight, fierce little circles, and she forget everything else as pleasure overwhelmed her, her head falling back as she howled in raw pleasure. That was all it took to get her off? Heh, she was more pent up than even I had thought. Must come from having somebody to watch her, her exhibitionist streak coming out in full force.

Speaking of exhibitionism, as I shoved two fingers into Benny's slit, making her squeal like a puppy as I started to brutalize her G-spot, I glanced over at Bird. Her eyes were locked on the scene before her, shifting slightly to take it all in: Benny's face as it went through all the expressions of much-needed release; Benny's breasts as they swayed back and forth with the thrusts of my hand; the collie's well-stretched cunt as I gave her a third finger, her tailhole clenching visibly as she hit another orgasm, and then another, until it seemed like she just couldn't stop; my cock, standing straight out from my body, hard and leaking, my own needs left unfulfilled; then up to my eyes, meeting my gaze.

The naked human teen's cheeks flushed as she realized I was looking at her, and she turned away, even as my eyes slid down her body, drinking her in. Bird had high cheekbones and a cute, slightly upturned nose. Her dark blonde hair was longer, down to the middle of her back, and presently unbound, though I got the impression from yesterday that she normally kept it tied back in a ponytail. Slightly upturned breasts swept out from her chest, each facing slightly outward, showing off the decent tone of her chest, the nipples capping each breast perked and erect, the aureoles fairly small with a pleasant pink rose color, making them stand out clearly from her pale skin. The girl's belly, as I told her before, was firm, tight, and rippled slightly with the sleek muscle earned from countless situps, while the bones of her hips were just barely visible at their points, showing clearly how little excess body fat she had, while not showing so much as would be expected from someone who was undernourished. I gathered that Bird shaved herself all over her body for sake of hygiene, probably something she learned in the locker rooms she obviously frequented. Not that I minded in the least, as it left the clearly-defined indentation of her sweet-smelling slit totally exposed to my view. Just looking at Bird made me start to drool despite myself, and I hastily averted my eyes as she mustered up the courage to look at me again, knowing what a sight I must make, slavering over her naked body like some starving animal at a piece of meat.

Instead, I pulled my fingers back from where they were pumping Benny's pussy to the depths, and plunged my muzzle down, kneeling as I did so to get better leverage, my tongue finding and then shoving roughly into her gushing slit. This made Benny's whole body jerk and convulse upward as she howled again, her hands grabbing and mauling her breasts, her fingers pinching the nipples until I was sure they'd come right off. Moving my lips against her labia, my lower jaw bumping against her clitty, my tongue arching and rasping against her inner walls, stretching them like a prehensile penis, I did all I could to blot out the smell of heated human from my senses, instead filling them with the smell of a needy little bitch in heat.

Suddenly, with a final, prolonged wail of ultimate pleasure, Benny's whole body gave out on her and she collapsed forward, tumbling the hurdle she'd been leaning against right over in the process. Guess I'd gotten too much into it, been too fierce in my need to forget the forbidden lust for a human girl that had been filling me, and had forgotten about Benny's limits, and about my own words to just give her enough pleasure to "take the edge off." Now Benny lay flopped on the ground, her rump held high, her cheek pressed against the dirt of the track, her tongue lolled out, a truly goofy look on her face. This was one properly-pleased pup.

While I was still kneeling there, my cock standing straight out from my body, making up my mind on whether I should just breed Benny again right there, so as to relieve some of my own pent-up needs, I heard a girlish giggle from nearby, and turned to look without thinking. Bird was smiling as she looked at Benny's expression, walking over next to me, resting one hand on my shoulder as she got a better look.

"She looks happy," Bird said with another giggle, not seeming to realize how close her bare little cunny was to my nose, or just how sensitive my sense of smell really was, my senses flooding with the heady aroma of her needy moisture. "Wow, just...wow. It's always so hot watching you do that, Spike. You always make girls happy like that?"

"It's just a part of the job," I said, clearing my throat, as I knew my voice was more than a little husky as I fought to control myself. Please walk away, Bird. The session's over. Come back later, when your friends will be here, and I can get my rocks off in Benny properly.

"Well, it looks like a lot of fun to me," Bird continued, taking a few steps away from me, letting me start to relax as she seemed about to head off. But then, instead of leaving, she turned around, and bent over, gripping another of the nearby hurdles as she thrust her bouncy bare bottom back towards me. "C'mon, Spike," she said with a wiggle of her hips. "Don't I get a reward too?"

Son of my mom.

No male should have to endure this kind of torture.

At any other time I'd have just given that fine little butt a smack and sent Bird on her way, pouting and disappointed like any properly chastened teenager. After all, she was probably just in the throes of morph mating pheromones, something both Benny and myself were producing at an overclocked rate, Bird's teenaged mind completely unprepared to resist such a potent hormonal signal. Now, though, I rose and stalked towards the fine little bitch who was presenting herself to me, eager and needy as she stood on tip-toes, all the better to thrust her perfect buns out towards me in open invitation. I was nothing more than a brute beast as I rested my forearm over the top of her buttocks, gripping her left cheek with my right paw, giving her a squeeze as I lowered my muzzle to her flushed, wet and very snug cunny. To my instincts, I was scenting a fresh, healthy bitch puppy, just recently mature enough to begin breeding. She wasn't in heat, but she was curious about mating, and eagerly aroused by what she'd seen so far, and wanted to find out more through experimentation. This pubescent youngling was trusting me to be the one to show her how good mating could be. The thought made me smile with gentle pride as I stroked her smooth bottom, patting her gently to let her know she was in good hands, that I'd treat her right, and would stop if she changed her mind partway through. I might look like a brute, and I might act like it a lot of the time, but, well, I'm not that kind of brute. Not the sort to mistreat a femme if I can help it, outside of the context of training. Never the kind to rape.

Lifting my hands, I rested them on Bird's shoulders, working the fingertips into her tensed muscles, gently coaxing her forward so that her legs bent slightly, her body resting against the hurdle, pressing just beneath her breasts. Those breasts were my next target, my hands first stroking down her back, and then around her waist, and finally up her front, clawtips teasing her tight tummy, making her shiver in a moment of ticklishness, before I cupped those plump little handfuls. If Bird didn't work out as much as she did I could tell that her breasts would have been quite a lot bigger. As it was, they were enough for me to lather up with my muzzle, which I proceeded to do, bending over her shoulder with my head to better reach, my fingers squeezing and rolling her sweet little nipples. The honey blonde hottie's head lifted, her mouth opening in a loud gasp at the rush of sensation. Her body trembled as she closed her thighs slightly, feeling my heavy, engorged cock standing straight between them. This girl was mine, and we both knew it, the thought driving us both crazy with lust. Bird would let me do anything to her in this state, and that's exactly what I intended to do.

Reluctantly releasing her breasts, giving each nipple a long, lingering final suckle, releasing them with a soft, wet 'pop,' my paws moved down Bird's body to her fine tush. Soon my palms were roaming her smooth pink butt, squeezing and caressing, clawtips tickling her a little as I stroked down her legs to the sensitive spots behind her kneecaps. First giggling and then moaning loudly as I knelt to lick and then to suckle gently on those seldom-touched spots, Bird looked back at me over her shoulder, her cheeks flushed, her eyelids heavy with arousal, her breathing coming fast with her intensity of passion. Then my muzzle lifted to meet her flushed, dripping little cunny, her juices already flowing down her inner thighs, and Bird's whole body convulsed, her head jerking up and back at the sheer force of sensation that hit her inexperienced body and brain. Of course, even if she'd had any experience with a human male, there was nothing that could have prepared her for oral sex from a canomorph. My long muzzle, equipped with vastly more facial muscles than a dog, and with more complexity than those of a human, was perfectly suited to simply engulfing Bird's cunny and suckling on it like a drippy candy treat. As for my tongue, Bird soon discovered just how good that could feel as I first teased it against her inner labia, just dipping the very tip past her inner gates, before I thrust my head forward, driving the whole smooth length into her, even though I had to fight against the insanely rapid clenching of her tight inner muscles for every fingerspan. I noted that Bird didn't have a hymen, a momentary stray thought that pierced the haze of desperate lust that was enshrouding my senses, and was grateful for it. Knowing teenaged girls, eager to stuff anything vaguely phallic into their ripening pussies the moment they realize what they're used for (a stage some teenaged boys go through as well with their bottoms), to say nothing of the vast number of other ways in which a maidenhead might end up a casualty of growing up, I shrugged it off, storing it away as a question to ask at a later time, when we both weren't so desperately in the throes of primal, bestial lust.

Drunk on girljuices, I pulled my muzzle back, my tongue sliding free of Bird's reluctantly-gripping cunny only with some effort, her body going limp against the hurdle the moment contact was broken, with Bird panting heavily, like a marathon runner at the end of a race. For a moment I looked down at my throbbing, painfully engorged member. No, I wasn't going to mount her. Not yet, anyway. She was mine now, and I would do this properly. After all, I wanted her to stay mine. So, instead of simply stretching this eagerly presenting cutie's cunny open with the thick wedge of my penis, I rose to my feet, gripping her bottom for a moment, and then slowly squeezed a single finger into her. Bird's body tensed at this, her anus clenching in a light flutter, which soon increased in intensity as I added a second finger to the first. While I squeezed a third finger next to the first and second, taking my thrusting nice and slow, giving her plenty of time to adjust, I moved to Bird's side, so that I could better look down on her as she gripped the hurdle so tightly, her knuckles had turned white. Sensing my change in position, Bird looked up at my questioningly through the haze of pleasure over her mind, before her eyes widened a bit as I pressed the index finger of my other hand against her lips. Comprehension dawned on her face as I added gentle pressure to that finger, and her lips parted, wrapping around my finger as though it were my penis. She looked up at me for approval, and I grinned down at her, nodding. This was all the encouragement she needed to start moving her head forward and back, finger-fellating me with all the eager enthusiasm, and commensurate lack of skill, appropriate to youth. This was just practice, of course, getting her ready for the real thing, and even unskilled as she was, that enthusiasm made up for quite a lot of her lack of refinement of technique.

Bending my head, my hands moving as fast as Bird did, pumping her from both ends, driving her to ever-greater heights of pleasure, I ran my tongue over the girl's smooth shoulders, and then down her back and over her fine, rounded rump. Then, with an accompanying loud gasp from Bird, my tongue slipped between those pert, rounded cheeks, and began to tease and tense against her tightly-clenching anus. As light-skinned as she was, it wasn't too surprising that this little pucker would be a similar color, hardly more than a pink indentation, just waiting to be stretched to the fullest. Bird looked back at me, turning her head as much as her finger-fellatio allowed, her expression somewhat concerned as she realized what I intended to do. I lifted my head slightly at her expression, pulling my tongue away from her rear passage, and gave her lower back a reassuring lick. This seemed to make her relax, and she turned once more, starting to moan in deep pleasure as she was filled by my fingers from both ends, moving against my hands, eager for still more, trusting me completely. I had no intention of betraying that trust.

Tasting Bird as I pressed my tongue forward and down, wriggling the smooth oral muscle as I did so, I found that she was one of those people who showers before they exercise, and probably showered again afterward. She smelled and tasted of honest sweat and the perfume of whatever soap she used, something fruity, and lightly of stick deodorant. Perhaps if I'd been a human, the effort of squeezing my tongue into Bird's bottom would have disgusted me. But, thankfully, I'm a morph, and we have a different sense of aesthetics. For me, I picked up a lot of information about Bird, more, probably, than her doctor would notice on a routine checkup. That, and I soon learned that Bird was one of those girls that could be trained to enjoy anal sex, with a little gentle treatment during her first time.

Closing my eyes, my head slowly moving forward and back, carefully stretching Bird's butt, my fingers doing the same to her pussy, while the fingers in her mouth gave her a chance to practice her own oral play, I savored the moment, reveling in just how totally I had dominated this human bitch. Of course, as in all relations of dominance and submission, this was a position of the greatest trust, and the greatest potential for abuse. Also of course, if I was anything but what I was, a morph, made by humans and entrusted with serving them down on my most basic, genetic level, Bird might have been in some danger. But I was a morph, and she was in the best of hands.

Still taking my time, not rushing things, not doing anything to shock Bird from her euphoric state, I drew my tongue back, tugging it free with a little bit of effort, grateful for the slickness of my saliva to ease the way. I started to rise, my fingers pulling back, then popping free of Bird's cunny. As I raised my soaked fingers to my muzzle, licking them clean with relish, Bird looked back at me again, her face pouting cutely as I withdrew my fingers from her mouth. That moment of disappointment passed instantly, however, as I gripped her tight, rounded buns with my hands, grinning at the 'eep!' of surprise that escaped her as I let my heavily leaking erection flop like a hotdog into a bun between her rearcheeks.

"Oh!" she exclaimed as I squeezed her buns together, thrusting my hips to drive my cock through the tight channel formed, spurting little jets of precum over her back and bottom as I did so. "Oooh!" she moaned louder as I suddenly angled my cock downwards, rubbing the top of its length against her smooth, heavily-leaking little cunny, making sure to make almost the whole shaft stroke her clitty coming and going, my hips picking up the pace, making the human girl's body start to rock with my eager thrusts, the sounds of her rising girlish arousal sweet music in my ears. "OH!" she suddenly cried out as I pulled my cock back a little bit more, the swollen, mushroomed head catching in the cleft of her cunny, her whole body tensing up in anticipation. I didn't leave her in suspense. "OOOH!" she got out in sweet ecstasy as I slowly, so slowly, drove my cock into her, watching her labia spread open around the head, then clasp tightly around the shaft as I sank myself forward and in, not stopping or even pausing until my balls bumped against her trembling inner thighs.

Licking Bird's smooth back, tasting her sweet sweat, my hips started to hunch, slowly at first, and then quickly picking up speed. The girl's noises of rising pleasure were a backdrop to the roar of lustblood in my ears. She said a lot of things, how this was nothing like how she thought it would be, how it was better, how she loved it, how she wanted more, how her friends would never believe it, and then, finally, she stopped saying anything at all, her words melting into loud, squealing cries of pleasure as my hips started to slap her pink bottom, quickly turning it nice and red. She was screaming before too long, and I felt her inner walls clench around me as though she were trying to squeeze my cock right off. I didn't give in, though, didn't let that stop me - she was mine, and I wasn't finished. Not by a long shot!

Suddenly, as I gave Bird a particularly rough lunge of my hips, the hurdle gave way, tumbling forward and taking her with it. My hands were there, though, catching her under her arms almost before she realized what was happening, lowering her to the ground, pressing her head down to her arms as they folded beneath her, then moving my hands back to her tush, hiking it high as I plowed almost straight down into her. Every wail of orgasmic pleasure just made me even more brutal, until I was pounding that sweet teen twat for all the girl was worth, rutting her like the beasts that we were at that moment. Feeling Bird almost on the edge of total collapse, knowing in the back of my mind that she wouldn't last much longer under such rough treatment, I grunted, snorting like an animal as I stopped holding myself back, letting my full, heavy balls relax slightly as I ground my hips with each thrust, making sure to stimulate every last part of her inner walls that I could reach without injuring her.

Then it was my turn to howl, my whole body tensing up, back arching, head snapping back as I vented my cold orgasmic cry to the early morning sky. There was a rush of release from my loins, and my howl was cut off with a deep, guttural grunt as my cock started to spurt cum, gushing it actually, filling Bird's tight cunny right up to the brim in moments, and quickly starting to leak out around the lips of her wide-stretched labia.

Pulling my hips back, my cock bobbing as it popped free, spattering droplets of cum onto Bird's bottom and back and legs, I grinned as I looked down at Bird's heavily-leaking, well-stretched pussy, gripping her butt with one hand to spread her open, all the better to admire my handiwork. Bird's face was flushed, almost beet red, as was a lot of her body at this point, and she was breathing heavily, obviously right on the edge of total mental and physical exhaustion. Even so, I wasn't quite finished with her. No, I wasn't satisfied, not yet.

Crawling around Bird's prone body, lying on the softer sand around the hurdles (to make any accidental spills less painful), I rose to a kneeling position in front of her, my erection still standing proud. Reaching down, I gripped the poor, exhausted girl by the top of her head, lifting her gently until her mouth was only a hair's span from the still-leaking tip of my cum-coated cock.

"Suck," I ordered her, watching with amusement as her eyes went from near-sleep to confusion to comprehension. "You need to get me nice and slick, Bird: I'm gonna stuff your tush next."

This sent a shiver through Bird's whole body, before her mouth opened obediently, and she slowly, tentatively gave the very tip of my glans an experimental lick. Apparently I passed the taste test, as she leaned forward slightly, my hips moving forward more to reduce her work in her near-exhausted state, and wrapped her lips around my swollen cockhead. Looking up at me with those sweet blue eyes, she seemed to be silently seeking my approval. I gave it as I gripped the top of her head, stroking her like a good puppy, grinning and nodding as she began to slowly bob her head forward and back. Before too long, she was picking up her speed, bringing a deep growl of rising pleasure from my throat as she did her best to please me, my head rising, eyes closing as I basked in the exquisite sensation.

When I opened my eyes again, I was looking straight at Benny. The collie had risen to all-fours, and was staring, her jaws agape, at me and Bird. No, to be more precise, she was staring at a forbidden act: a morph male mating with a human female. Perhaps at another time, in another situation, I would have felt some guilt at my behavior. Perhaps I still would, later on. But right then, I had just left a sperm cream pie in this human hottie's cunny, and was getting plenty of eager oral attention from this completely willing and eager female who was submitting to me totally, trusting me completely.

Instead of feeling guilt for my actions, instead I saw an opportunity. Now was the time for Benny to prove that she really was a good, obedient girl after all.

"Lick her clean, Benny," I ordered, using my command voice. Bird's body tensed as she realized who I must be talking to, and what I was asking her to do. Benny's body tensed in shock as she realized the same things.

There was a long moment of tense silence as I stared at Benny, and Benny stared back. It was more in shock than in defiance, and so I forgave her this less than submissive behavior. Then, her mind finally managing to process what I had ordered her to do, able to work past that barrier instilled in morphs from our earliest days of psychological conditioning through the force of her even more powerful desire to be good, Benny's eyes lowered, and she crawled forward, ears and tail down meekly, showing her full submission to my will.

"Good dog," I said with a smile, nodding my approval. In moments, Benny's tail started to wag, her ears perking up, and she eagerly seized Bird's bottom, thrusting her slender muzzle forward. It was a pity that I couldn't see what Benny was doing to Bird over the heart-shaped swell of the human's smooth buns, but judging from the loud moan Bird gave around my cock in her mouth, it had to be pretty good. Obviously Benny wasn't a novice at giving pleasure to females, though I supposed that made sense, considering that we male dogs regularly sexually experimented with each other in our kennels, back when we were all government property. Obviously it must have been similar for the females. This seemed to be all that was needed to break Bird out of her momentary state of indecision, and she also began to bob her head once more, almost choking herself on my cock several times in her eagerness to please me.

"Such good girls," I growled softly, slowly pressing on Bird's head as I drew my hips back, my cock popping free of her mouth, bopping her on the tip of her nose as it bobbed in the chill of the morning air. "Lie down on your back, Bird. Benny, get on top of her. You'll give each other pleasure while I deflower little miss Bird's tight tush."

Bird seemed stunned by my words, unsure of what to do next. Obviously this was more than she'd thought would happen in her wildest fantasies, and it was surely a moment of nervousness for her as well. After all, anal sex, done wrong, could hurt. A lot. But my hand was nudging her shoulder, while Benny was nuzzling her hip from behind, and, with a nervous gulp, Bird did as she was told, rolling over onto the grass by the track on her back, her knees bent in the air to let her plant her feet firmly on the ground, her hands at her sides, her lovely young breasts heaving with her prior pleasured exertions.

The moment Bird was in place, Benny gave an adorably happy yip, making both Bird and myself smile, and crawled to Bird's prone form. She quickly climbed over the human girl, spreading her legs as she lifted her tail high, giving Bird a clear (I hesitate to call it a "bird's eye") view of Benny's moist cunny as the colliemorph lowered herself down onto Bird's body. Her soft fur must have been comforting to Bird, because I could smell her nervous tension start to fade. And when Benny lowered her muzzle to Bird's bald little slit, her tongue sluicing through those tightly-clasped cunny lips, Bird's hips lifted as she cried out, her cry cut off suddenly as her mouth connected with Benny's lowering muff. In moments the air was filled with the soft, muffled moans and eager slurping of the two femmes as they went to work on each other. Bird, as it turned out, showed as much eager enthusiasm, once she'd gotten past her initial inhibitions, for eating cunt as she did for eating cock.

Spending a few minutes watching this sexy display of feminine lovemaking, folding my arms and letting my cock throb for a while as I let my lust simmer for a bit, my eyes followed Benny's fingers as she teased them down the crease of Bird's perineum, and then in a snug circle around the human's tightly-clenched pink ring, making the girl's hips thrust upward once more, her toes curling, digging into the grass. Now was as good a time as any, I reasoned, and I stepped forward, stroking my cock, getting it slick with precum. As I knelt between Bird's wide-spread legs, I thrust my hips forward, letting my cock jut straight at Benny's muzzle when she came up for air. Her brown eyes widened at this, but she quickly reacted, taking me easily to the roots, my balls pressing firmly against her chin, demonstrating the advantages of oral sex with a long muzzle. Bobbing her head a few times, while Bird squirmed impatiently under her canomorph femme lover, Benny got me nice and slick, then pulled her muzzle back, giving my glans a final swirl of her smooth tongue before angling my shaft downward, towards the clear bullseye of Bird's pink virgin pucker. Bird's body tensed a moment as she felt the heavy head of my cock pressing against her last virginity. As I started to gently ease myself forward, watching as her rosebud slowly parted around the thick cone of my glans, Bird's legs kicked slightly, a long, muffled whine escaping her throat from her place beneath Benny's cunt. But then Benny lowered her head, and started to lash her tongue over and into Bird's sex with a will, arching a finger into the girl's smooth-shaved cunny for good measure, and almost immediately Bird's whines of discomfort and fear turned to moans of pleasure. Those moans rose to a crescendo as I pushed forward just a little more, and suddenly felt the corona of my cock pop past Bird's anal ring. The hardest part was now over, and I grinned, watching Bird's toes curl upward as I continued my long, slow thrust forward, not stopping until my balls were squeezed firmly against her tight buns.

I paused then, just savoring the moment, watching Bird's rump clench, her legs kicking slightly as Benny continued her oral attentions, dab-dabbing her tongue over and against and into Bird's heavily-leaking cunny and throbbing, erect clitoris. It was at this moment that I heard a soft whirr from the many cameras lining the track: Girl was watching. How long she'd been watching I couldn't tell, since my attention had been too distracted to notice, but it must be Girl there, manually adjusting the angles of the cameras for the best possible shots.

There wasn't much time for me to consider this realization, though, before Bird's own head suddenly lifted, and Benny gave a squeal of pleasure straight into the smooth-skinned girl's sex as Bird started to get into the spirit of things, returning the favor as best as she could. Feeling Bird's butt tighten around me as she did so, I took this as a challenge for me to keep Bird's attention, while still taking care not to overdo it with the delicate tissues of her rectum. Feeling my own rump tighten as I grit my teeth, focusing my full concentration on the task at hand, I started to slowly move my hips, pulling back a finger's width, then thrusting back in. The next withdraw was two finger widths, and then three, and soon I was pulling out almost to the head of my cock before driving myself back in. In slow, tension-filled minutes my hips sped up, building in tempo, my stance set in determination to fight through the sudden clenching that came in infrequent intervals as Bird went through still more orgasms, more, probably, than she'd ever thought were possible. I was a beast possessed, though, and didn't stop, didn't let her cool down for a moment. No rest for you, Bird. You're mine now...mine! A sharp bark escaped my lips as I started to thrust with gusto, feeling Bird's body react accordingly, her entire body shuddering and jerking beneath Benny's as the colliemorph did all she could to keep pace with me with her muzzle and tongue and fingers. Behind Benny, it was obvious from a glance in that direction that Bird was doing all she could to keep up as well, but her movements were getting steadily more jerky, more erratic, until her head jerked back, her back arching so powerfully that it lifted Benny right into the air for a moment as Bird screamed, loud and long, her hands clawing at the grass, legs kicking in desperate pleasure, pleasure so powerful that it consumed her entire body, more pleasure than any teen should be made to endure. The sight, the scent, the sounds, it was too much for me, and I felt my balls contract hard as I came once more, thrusting my cock to the hilt in the human girl and starting a series of short, almost brutal thrusts that just seemed to prolong her own series of earth-shattering orgasms the same way it prolonged my single one.

Eventually the storm passed, and I heaved a long sigh of relieved tension as I pulled back, my cock flopping heavily downward, completely deflated. If I wanted to, I could have geared myself up for several more ejaculations, just like any healthy morph could, but I'd put a lot of myself into the two that I'd had already, all of it centered on giving Bird as much pleasure as possible. That sort of prolonged effort is a workout in itself, and I felt completely sated, my instincts settled down at last, letting me think more clearly. With that new clarity of thought, I looked at Bird, who was simply lying there as Benny rolled off of her, looking dazed and very nearly asleep. Considering what she'd just been through, that was very likely the case.

"Head back to the kennels, Benny," I told the colliemorph, giving her a gentle pat on the bottom, my softer touch and tone of voice letting her know how pleased I was with her performance just then. "Take the clothes with you, and get yourself cleaned up."

"Yes, master," she replied, tail wagging, and immediately rose to hurry and comply with my commands. Yeah, she was a good dog after all, like there'd ever been any doubt. She'd just been pent-up and a little bit too pampered by humans that didn't understand how to handle canomorphs. If she'd been really, truly spoiled, I'd never have gotten results as fast as I did. Now it was just a matter of turning her obedience onto her mistresses, and making sure she stayed that way. And for that, I'd need some help from Rachael McMichaels.

"C'mon," I said softly to Bird, bending slightly to lift her into my arms, and then rising to my feet. "Let's get you to bed. You're gonna need some rest after all that work." I lowered my head to affectionately nuzzle the girl as she quickly drifted from consciousness, taking her scent to make sure that she wasn't in any distress or discomfort. She wasn't. Quite the opposite, actually. "We'll wake you up for lunch."
