A Little Like Estrus

Everyone likes weekends. Everyone but the gryphon, Ceylon. They worked a pretty busy job, keeping themselves occupied most days without any real breaks, but they weren't exactly the most punctual. So, while they were free to make any hours they wished and take any days off they wanted, oftentimes they didn't get as much work done throughout the week as they'd like, resulting in them shifting that work to the weekend. It may have been poor time management, or maybe it was because they took on too much work and got distracted easily. Either way, the end result was that they rarely had what one would usually consider a 'weekend'.

If anything, the weekend for everyone else was that time Ceylon could focus on work without anyone at the office. They actually got more work done this way. People were often a distraction. Even the right people made things difficult for them. Ceylon was always eager to clearly communicate the reality that their personal attention was not reflective of their opinion on that person. Even their best friend was often too much of a distraction to keep around when they were trying to work.

On this weekend, however, they had a different distraction keeping them from work.

Ceylon was neither male nor female, and both at the same time. They had no real concern for pronouns but often defaulted to gender-non-specific, even though they happily accepted male or female tags depending on their mood. On this weekend, she was taking a far more feminine identity. Her vulva throbbed with need and her depths desired all a sire could offer. She wasn't experiencing estrus in the traditional sense, but her fluid gender meant that her hormones were constantly fluctuating and were prone to random spikes in all directions. She was sterile, but that didn't stop her body from demanding things from her she wasn't always prepared to handle.

Usually she'd just casually sit on a toy while on her computer, but that wasn't quite the same as the real thing. She did actually have a rather large, anatomically correct replica of her own male parts that she liked to use when in her female form, but that felt a bit too self-indulgent to play with. That toy was a fantastic fit, but it lacked the fleshy warmth of an actual partner.

As she tapped her claws on her beak, the reflection of her computer screen distorted on her eyes, she internally went through the list of all the folks she'd likely be able to call up for some fun. She had many partners that loved having fun with her, since she had almost no limits in terms of what she'd handle or who she'd invite into her, but most of them weren't available this time of the week. It was late on the last day of the weekend, most were resting up for work the next day.

There was really only a small pool of potential partners available given that circumstance. It took next to no time for her to realize the most perfect partner for her on this horny evening. Her dragon friend, Lethias, was always available for fun with very few exceptions. So open for companionship that she didn't even bother sending him a message before heading out. She knew he wouldn't say no, and things were a lot more fun when they were spontaneous.

She tapped her toes on the ground to let her partner, Leera, know she was going out. Her naga mate was not the most sexual creature, and thus often encouraged Ceylon to find fun with others. It worked better for her and for Ceylon, as neither of them were monogamous and both shared such a strong emotional bond that they trusted each other.

On her way out the front door, she grabbed a very specific potion and downed it, tossing the vial in the sink from half way across the room. This potion was specifically one that she knew Lethias would love. A wonderful surprise he'd enjoy if things went the way Ceylon planned.

With a bit of focus, she was able to activate some transformation magic to grow wings, allowing her to take to the sky. She lived on a high-rise cliff-top apartment, the home she shared with Leera a fully featured cave den far away from others yet still fully wired for internet and power. She leapt off the cliff, spread her wings, and caught a thermal to rise high in the sky, one that allowed her to glide all the way over the lake and towards her best friend's place.

Lethias didn't live anywhere near her. They were two cities apart or so, a fly that would easily have taken a half an hour had she been simply gliding. She was in a hurry, though, so she used some aero magic to give her a bit of tailwind, propelling her through the sky over the lake and down the river.

Lethias lived in a rather glorious log house, like a cabin in the woods but erected off the ground and connected between four different trees. More of a tree house than a traditional log cabin. His home was three stories tall, with the bottom floor a solid twenty meters off the ground. The trees in this area were quite large, each of them easily fifty meters tall or more. The entire region was quite rich with vegetation and wildlife. Both Ceylon and Lethias preferred it this way.

Upon arrival, she did a single spiral and landed heavily on his front porch, under the awning and on the railing like a birdy perch. Her feline hind claws lacked the same grip of her hand-talons, but she made due. While there, she used her transformation magic to re-absorb her wings into her back, leaving her flat-backed. She then hopped down and didn't even bother knocking, she just grabbed the front door and walked in. "Oh Lethias!" She called out, her voice echoing through the open-form home. All three stories were merged on one side of the house, with the other half being stacked in a more traditional sense. The open half was also lined by dozens of massive, ornate windows. There were many good reasons for such an open, unrestrictive setting for this dragon in particular.

A moment later, lethias poked his head out from the door of the highest floor's room. His personal keep, where he kept his hoard. "Hello?" He called back, not sure what to make of this. Once he saw it was Ceylon, he got of a bit of a look of frustration. "You really could have told me you were coming. I'm online, you know."

Ceylon gently closed the door behind her, slipped past the kitchen, and hopped up the first flight of stairs to the second floor. "I could have, yeah. But I figured it was a tonne more fun to surprise you!"

"I am sure you did, but it wouldn't have taken any effort to leave me a message. Something wrong?" He had a tone of concern in his voice.

"Nothing's wrong, no. Well, not 'wrong', but I do gotta find a solution." She explained, still quickly making her way around the walkways to the third floor, where Lethias was still poking his head out the door and over the interior balcony. "I think you can help me."

Lethias paused for a moment and blinked, chest heaving a bit as he pondered. "What do you need? You're not in trouble, are you?"

"Hah, no. Not in trouble. Told you, it's nothing to be concerned about." She leapt up the last few stairs so she was just outside Lethias's door. Nude. She didn't often wear clothes if she didn't have to, and both her home and Lethias's were far away from the city. She didn't need to worry about that. He was a full head and shoulders taller than her. He was a thickly-built, above-average biped dragon with red scales all over, a pair of blue strikes over his shoulders, and yellow ventral scales.

He looked up and down her body, expressive ear frills perking up. "Okay, then what's up?"

Ceylon wasted no time. She pushed into him, practically tackling him through his door frame into his keep. He stumbled back, his hand catching a box of cards and making them fly all over the room before he fell onto his rump. Ceylon quickly reacted to this by using her physical magic to grab each and every card in the air before it fell and quickly placing them neatly back into the box, gently placing the box off to the side.

"My cards!" He whined, his tone a mix of subtle rage and disappointment.

"What? I put them all back. They're all in the box, still."

"No, I was sorting them. They're not sorted anymore." Lethias said, his voice deflated. "Now I have to start all over. That took all afternoon."

Ceylon's eyes went wide as she realized what she had done. As a gryphon with a near-fetishistic love for organization, she knew and respected the art of alphabetization. "I'll help you with it when I'm done, okay?" She kept him pinned to the ground, hands on his chest and knees on either side of his hips. "I'm pretty sure it'll be worth it."

It didn't take long at all for Lethias to figure out what it was she meant by that. He reached out and lightly caressed her belly, running his claws through her fur. "I suppose I can forgive you, just this once." He couldn't help but clench his loins, slowly pushing his member out. He, like Ceylon, didn't wear clothes when and where he didn't have to. "What brings you to me, today?"

"Just one of my moods." Ceylon confessed. "It was quite sudden and I knew you'd be the best option to help me take care of it. I hope you don't mind. I got a list of guys I can hit up if you don't-"

"You chose me first?" He said, his eyes lighting up and the corners of his maw tugging.

Ceylon considered joking and saying she'd gone to others, first, but he knew that wouldn't be the truth and as a joke it was more mean-spirited than she wanted to sound. "Well, yeah. Why would you be any lower than my number one?" She crawled off him and rolled onto her back, exposing herself to her dragon friend. Her plump, equine lips were already moist with arousal and leaking beads of natural lubricant down onto her velvety-soft, round tail hole. She didn't bother with foreplay, she just started rubbing her clit and parting her lips to reveal the bright cherry-pink folds hidden beyond the shiny black outside.

Lethias may have been pretty tame in many ways, but he knew an invitation when he saw one. It took him a moment to find the fortitude to act or react, but he still rolled onto all fours and crawled over her, his hot breath tickling her plumage. "It's not often you want me this badly." He commented, slowly slipping his hand between her thighs and spreading her legs apart so he could slip a finger up into her, soaking his digits between her lips.

"That's the secret, isn't it? I always want you, just one of us are always busy. Or, you know, the mood isn't there. When the mood's there - like it is now - I always think of you."

With a gulp and a blink, Lethias locked eyes with Ceylon. It looked like he was about to cry.

"Oh, cut it out. How could you not know this?" She raised up her leg and put both her hind paws on his shoulders, gripping his scales with her claws for balance and leverage. This ensured his gaze was focused more on her lower abdomen and more specifically her loins. She knew where he needed to focus, and it was awkward to share a gaze when she was getting pounded.

The two of them were familiar enough with each other to know what came next. With Ceylon on her back and presenting so shamelessly, he knew what she wanted and how badly she wanted it. Sometimes they needed lube. This was not one of those days; Ceylon was soaked.

Lethias gently pried her feet from his shoulders, finding the claws in his delts to be a bit distracting. He laid her feet down on either side of himself as he started slipping his fingers up and down her slit, deliberately rubbing his thumb against his fingers to spread her fluids all over himself. He paused at the end of each stroke to slip two fingers into her depths, caressing her walls while tugging at her lips from all angles. He was doing all he could to loosen her up, to let her relax.

And she was loving it. His fingers were quite large compared to her, but she always wanted more. She arched her back and spread her legs, one hand still on her clit to squeeze and tug it as Lethias probed her depths. Her walls quivered and relaxed, clenching and pushing out against him, her soft, velvety folds stroking his digits as he continued to caress her. Both of them were doing all they could to help the other out, with Lethias using his specific set of skills to massage her walls while she was using her muscle control to clench and squeeze and strong him to the knuckles.

Before long, Lethias felt the urge to bring in his third finger, forming a triangular wedge that he used to dilate her depths. He pushed in as far as he could, only stopping once he felt her muscles constrict around him. He then pulled out and marveled at the slimy goop that soaked all three of his fingers. He used this slime to moisten his own slit, idly rubbing himself to coax his member from its depths, all while using Ceylon's juices to stroke himself.

Given that his soaked hand was now busily caressing his own length, he used his other hand to tend to Ceylon's plump lips. This hand was dry, but not for long; the moment he slid two fingers into her, she arched her back, chirped happily, and spurted a few gobs of her fluids into his palm. As her slime trickled down his fingers, he balled up a fist and laughed a bit as the fluid made sputtering sounds between his knuckles soaking the entirety of his hand as he did so.

Now completely darkened with gryphon fluids, he formed a wedge shape with his fingertips and thumbs, gradually forcing it into her. Her petite frame resisted him, so he started rotating his fist to use the ridges of his knuckles to massage her flesh and loosen her muscles. That, coupled with curling his fingertips inside her to press against her most sensitive walls quickly helped her to relax. As he pushed and twisted, she got a bit looser and a bit less tight, her flesh quivering as it gave way to his strength.

As he pulled away, he saw her thick lips parting to once again reveal the soft, bright pink flesh inside. The tone of her folds was so dark it almost looked like blood; he knew this meant she was at the absolute height of arousal. Most of the time he'd be gentle, reserved and sensual above all else. But seeing just how plump and tender her depths were and realizing how peculiar it was that she just showed up at his door, he knew he could be a bit rougher.

He pinned her down with his other hand, the one that he was using to apply her lube to his length. With all his weight down on her, he curled his bicep and forced his fist into her. While her muscles and frame resisted him, he kept pushing. He knew her safe word, if it was too much she'd have no problem speaking it and having him back off. Instead, she arched her back and clenched her fist, tail going wild with its tip flicking between his knees.

Ceylon was not yet where she needed to be but the strength she felt as Lethias forced his fist into her was exactly the sort of thing she came to get. She was a little sore, a little tight for this, but half the fun of sizeplay was exploring her limits and stretching. She pushed back against him, her fingers pinching her clit while her other hand did all it could to pry her lips to the side and expose more of her silken, crimson insides. The less of her outer folds got in the way, the easier her natural lubricants would allow him to force himself deeper.

All at once, with an audible sputter of fluids and air escaping, his knuckles breached her opening and lurched into her depths. His tapered fist plowed through her flesh until her opening came to squeeze tight around his wrist, every wrinkle of her walls struggling to constrict him. He was a little worried about this, that he'd hurt her, so he pulled out immediately.

This left her gaping, her cavernous walls parted and hollow. Her ebony lips glistened with fluids but wasn't as thoroughly coated as her insides. She didn't stay gaping for long. As she huffed and heaved with delight, her pussy walls collapsed, sealing her depths in a matter of seconds. She then winked her clit, peeling it out and making her vulva bloom like a flower for a moment while a spurt of her feminine ejaculate dribbled out and soaked her rump.

"Both." She demanded, pointing to his other hand. "I can handle both."

Lethias wasn't so sure of that. He required a bit of strength and pressure just to get the one in. "Really? Are you ready for that?"

Ceylon's toes curled as she squeezed her thighs together and winked her equine clit again. "Trust me, right now I could fly a plane in there. Might take some work but go for it." Once she was done she spread her legs again, deliberately slipping two fingers from each hand in her pussy and two from each hand in her ass pulling both holes open to reveal just how malleable her flesh was. Both tail hole and pussy blossomed open, drooling fluids all over the place and pulsating along with every heartbeat and every heave of her chest. "I could go wider if you want."

"No, that's okay." Lethias assured as he crawled back over her, once again pinning her in place as he formed a wedge with his fingers, slipping it into her gaping, cavernous cunt with ease. It seemed her spreading her lips and pucker helped to relieve any of the pressure that she was exerting upon him, because his entire fist disappeared into her folds without any resistance as her folds enveloped him to the wrist. Impressed and curious, he balled his hand up inside her, widening its berth to act like a knot inside while he bent his wrist and used his knuckles to grind against her walls.

She arched her back and clenched down with all her might, nearly forcing him out as her muscle constriction squeezed him so tight he could barely move. He tried, but it wasn't until she collapsed in defeat that he was able to once again wiggle around inside her. As he did so, she panted and drooled all over the place. The friction of his thick fist and knuckles was pleasuring her just right, nearly leaving her a sloppy mess. She still had to maintain some self control, so she did all she could to not push down and maybe force him out again; that sort of thing could invert her passage and few people liked that sort of thing. She knew he didn't.

Lethias was having a bit of a hard time not just diving right in like he preferred. His cock had fully emerged from his slit and was at full mast aside from his knot lobes, which were still subtle and ill-defined. They wouldn't swell until he was ready to climax. He wanted to bury himself in Ceylon, to give her the mounting she so clearly wanted. He also wanted to make sure she got stuffed properly first. So often she'd let him go first, this time he wanted to make sure she went first; she tended to prefer fists to cocks, depending on the partner.

He plunged his fist in deeper, gently twisting and rocking back and forth as he gradually got as deep as he could. He felt her plump lips slide past his wrist, all the way down his forearm, and wrap around his elbow all with accompanying juicy sounds before he gave up. Even with his bicep clenched and putting pressure on her clit, he couldn't find the limits of her depths. That would prove to bode well for him, as he knew from previous, educational encounters with her that a deep pussy was a horny pussy. The canal relaxed and lengthened to handle more when in the deepest throes of need.

It was hard for him to not bend her over and go at her immediately.

But with her walls easily taking his entire arm to the elbow, he knew he had a bit of wiggle room. Sure, her flesh was snug around his, but it was also soft and tender, easily stretched. With this in mind, he pressed his fingers against the forearm, squeezing the tips in between her plump vulva and his muscular scales. He flexed a bit to make his arm more firm and a bit thicker, then relaxed as he eased his second hand inside her up to the wrist, his palm pressed to his forearm.

This didn't last long. The moment she felt his second hand breach her lips, she clenched with all her might, pelvic muscles constricting in waves from her depths to her opening. This pushed him out, her slick walls and powerful contractions stronger even than the force he applied to try and keep inside. She managed to force both of his fists out with a guttural squelch followed by a sputtering as her fluids escaped her folds. She gaped, then sealed shut, then gaped again before her lips closed and her pucker twitched in delight. Her toes curled as she arched her back, clit winking and pussy oozing fluids.

"That's what I wanted." She cooed, every feather around her neck and upper body standing on end. "But I hope you're not done. I want more."

"Don't worry, I have more." He growled at her as he crawled over her for the third time. This time, he held his cock in one hand while he used the other to prop himself up, aiming his tip at her tender, soft folds. He got a nice firm grip and rubbed himself up and down her slit, pressing it against her clit a bit to apply pressure before forcing it down towards her tail, popping it into her with ease.

His entire shaft sunk into her folds as her black lips came to kiss the base of his member, slit to slit. He loved the sensation of her walls clenching and releasing around him, her every muscle contraction and relaxation caressing his length, meaning he couldn't simply stay still to enjoy the sensation for very long. He had to carry on, to begin to thrust into her with all his might.

The dragon's legs were very strong, and his arms were just as powerful. He hoisted her hind end up and bent over her, squatting in place as he bucked into her, slamming his entire length into her with each powerful thrust. He could feel her walls clenching and relaxing at the apex and bottom of every thrust, deliberately matching his pace with her own internal motions. She didn't move, but her walls kept clenching and pushing and relaxing and alternating between deep and shallow muscles to ensure she was always at the same point he was.

She was so expertly matching his motions with her insides that he almost felt like he was going to finish within less than a minute. After only a few moments of intense, carnal bucking he felt that familiar tingle deep in his loins, but it was quickly set atop a plateau as he felt her depths get extra tight around him. He wasn't about to climax, but he was held just before release.

As he looked down over his body, he noticed that Ceylon seemed to have shrunk. Her body, once about three quarters his height, now had to be half his height. His cock was so big compared to her he could see the faintest outline of a bulge in her lower belly bouncing with each thrust. Upon glancing around his room, he realized that everything was a bit smaller than it was before. He glanced back at her, noticing that her blue eyes were glowing teal.

That cheeky bird. He knew she was doing this to him, and he had no problem with it.

Upon further inspection, he noticed that his cock, even relative to his body size, was exceptionally large. What was once a tip that would rest heavily on his belly was now one that, had he pulled out of her, would have laid comfortably between his pecs. In fact, to test this theory he pinned Ceylon to the ground and yanked himself out of her, relishing at the burst of precum and lubricant that erupted all over the place and splattered on his floor. This left her gaping once more, this time cream-coated as his thrusting had whipped up their combined fluids into a foamy mess.

When he laid his member down on her belly, he found it was literally as long as her entire torso! A crazy difference in size, but she wasn't lying about being able to handle him. "What's going on here?" He casually asked as he grabbed his shaft and aimed his tip back into her, once again sliding his entire length into her depths until their slits kissed.

She pushed herself up from the ground, convincing Lethias to get up into a standing position with her legs wrapped as best they could around his hips and waist. "I took a bit of a potion before I left, one that mildly stimulated growth. Its effects must be transferring from me to you through my fluids." She winked at him and clenched down, winking her clit while spewing a gob of her lubrication down his belly and thighs.

He noticed that his muscles were swelling beneath his scales, pressing out against the red and forming defined lines and bumps. It was so clear he could literally press a hand against his thigh and watch as his scales swelled, each one parting from the others. This gave him plenty of stamina and desire, but also filled him with a subtle sense of dread as he realized he was inside his own bedroom and absolutely did not want to make a mess of it. Some of their fluids had already landed on the carpet and that was easy enough to clean, but he knew that his growing form would be too much.

Sure, his house was specifically designed to handle literal tonnes of weight being tossed around - he loved this sort of thing and planned accordingly, which was why half his home was a three-story open styled loft, but he was currently in his room and he had no idea how much potion Ceylon had used or how strong of an effect it took on him. Sometimes it made him house sized, sometimes mountain sized depending on mood. He couldn't risk it, so he clutched her close to his bulging chest and shoulder-tackled his way through his door before his shoulders grew too wide to breach it.

With his fully-formed cock now swelling inside her, knot lobes pressing out against her walls and locking him just beyond her opening, he did all he could to make his way down the spiral stairs all the way to the bottom floor, where his living room was. There, he had the entire three stories of his home above him, lined around the edges by rope bridges and large glass that allowed him to look outside from any of the three stories.

"How big will I get?" He asked, somewhat apprehensive but also hopeful that the answer was quite large. He didn't wanna damage his home or the surrounding area, but he also didn't wanna miss out on an opportunity to show his true self.

Ceylon wrapped her arms around his shoulders and hung off his chest as his bones elongated and his muscles stretched to catch up. "Not too big, you'll fit in here. I can control it, you know."

"How big can you make me?"

"Today?" She paused and glanced to the ceiling three stories above her. "Today, only as big as your home can handle. I don't have a tonne of energy and I'll have to bring you back down to normal size once we're done. I gotta get back to work tomorrow and want to, you know-" she sounded like she was about to continue that train of thought when one of Lethias's many swells hit his loins, resulting in his balls inflating to the size of beach balls and his knot doubling in girth inside her. She grunted and grabbed his horns to get some leverage but quickly found herself not large enough to reach past his bulging pectoral and deltoid muscles.

The potion had gone slightly awry. His bulging form was swelling and expanding faster than his bones caught up, resulting in a Lethias that was maybe a full story and a half tall with muscles clearly meant for someone twice that height. His cock, now almost the full size of Ceylon's torso, was so big compared to her that her entire body from loins to neck basically was just the shape of his member and knot, even going so far as to imitate his ridges down her spine.

Lethias knew it wasn't a problem, though, so he simply wrapped his arms around Ceylon's waist to hold her there as he bucked into her. His knot, which kept them firmly locked together, ensured that very little friction could grow between them, but that didn't mean that his lobes couldn't subtly shift and rock inside her. And, given how large he was compared to her, even the slightest shift felt like a full spin and full-length thrust.

Ceylon's eyes began glowing teal again, and within seconds of that Lethias felt a tingling in his loins as her magic coursed through her pussy walls, into his cock, through his midsection, and expanded from there to every one of his extremities from the tips of his wings and tail to his claw tips.

Almost instantly, he felt his internal structure begin to catch up. His once bulbous muscles kept their mass but stretched out to a more appropriate length. There was a deep churning within him as he heard - nay, felt - his insides and tissue adjusting and rubbing against each other. His muscle fascia stuck, then released quickly as each fibre expanded, the pressure between muscles growing and shrinking as everything grew to be more balanced between mass and girth and length.

All the while he couldn't stop thrusting himself into Ceylon, who he was mostly using as a cock sleeve. The more he grew and the more she seemed to enjoy it, the happier he was to test her limits and to give her all he had. She'd not uttered the safe word yet, so he had no qualms wrapping his hand around her torso to give an extra squeeze. What was once soft, tender flesh that squeezed him nicely was now tight like a condom around his girth, so taut that he sincerely expected to see a bulge when he finally climaxed.

She loved the difference in size but quickly realized the discrepancy between them was getting a little silly. Her eyes glowed once more and she siphoned some of the magic she funnelled into Lethias back into herself, through the link between them. Tendrils of teal mist billowed from his every muscle and every bulge to course through him and converge at the base of his cock, where it then entered her like an ethereal ejaculation, giving her that same swelling growth around him.

This halted his growth at about two and a half storeys of height, his massive feet each the size of a couch and his head the size of a bed. His cock, now once again proportional to his body and his muscles more balanced but still toned, all looked and felt wonderful to him. Further, Ceylon's swelling form gave him a super-tight squeeze around his length for a moment before she grew too big for him to keep his hands wrapped around her.

She rotated on his cock, her flesh twisting with torque before his knot lurched and shifted inside her until she was face down with her feet on the second floor balcony that was attached to a rope bridge. This gave her the perfect height, so she opened up one of the bay windows and reached out to grab the trunk of a nearby tree for leverage. She hissed back at Lethias. "Well? Go ahead! Finish me off, drake! No excuses!"

The gryphon was still half his height, but that meant his massive cock was still nice and snug inside her while his tip remained in a distinct bulge in her lower abdomen. He was bulging with strength and power, his arms flexed with the definition of a banana bunch as he gripped both her petite hips with his relatively massive hands. He dug his talons into the crook between her pelvis and thigh, sure to keep a keen grip as he pulled himself out of her with a pop, his knot exploding from her depths amidst a gush of precum and gryphon fluids. Not wasting a single moment to give her time to relax or clench, he forced himself back in, immediately capitalizing on her gaping depths.

She gasped and threw her head back, still gripping the trunks of the two trees so she could push back but not be pulled away as Lethias popped his knot in and out of her. This was not how knots were supposed to work, but her depths were so hungry and malleable that he had little to no trouble ramming her time and time again, his bulges squeezing and lurching through her opening to lock and unlock her flesh with every powerful motion.

As per their agreement, once they got to this point Lethias was to finish as fast as he could. He was capable of going for hours, or was willing to hold back and keep himself from finishing too early so his partner could also enjoy themselves, but he knew Ceylon and she knew she could count on him to have his way with her.

So he did. And he did hard. Perhaps harder than he ever had before. Certain that his home could handle his weight, he leaned into her and slammed his hips to hers repeatedly, forcing his knot in and out of her with every wild buck. Her tender lips were growing softer, less taut, and wetter every time until she suddenly clenched with all her might, clit winking and lips squeezing so tight around the neck of his knot that he couldn't pull out of her!

This added pressure and the tugging sensation was enough to break him. He leaned down over her and growled as he bit into her neck, his hot breath soaking her feathers as all his combined strength and power coursed through his loins, took a detour through his balls, and exploded into her.

His member throbbed and his knot pulsated as his balls contracted, forcing a deluge of his seed to course into her, filling her womb with all he had to offer. He could literally feel the cum-bulge of her belly as it expanded against the fingers that he used to hold her hips, each ejaculation shifting the weight a bit more and threatening to escape and backfire down his front.

He offered a series of brisk, erratic thrusts, each one accompanied by another, slightly weaker explosion into her depths until he finally collapsed on top of her, his entire body barely squeezing out the huge bay window next to her.

"Excuse me, sir." She elbowed him. "You're very, very heavy."

Lethias just grunted, jokingly pretending he was asleep or half lucid.

"No, You get off now, you had your fun, I gotta get back to work and I can't do that with your heavy ass pinning me down here." She was still tied to him, his knot locked into her depths with his tip pumping the last of his seed into her womb, where it would stay for now. She and he were both half inside his house and half out, her upper body on his deck while he was resting between two tall trees. She knew he was playing around so she used her feet to press against his thighs and pushed with all her might, forcing his slowly deflating knot out of her with a pop as she fell off the balcony, tumbling down the tree and landing on her back at the foot of Lethias's home.

He cried out and tried to catch her before she left his reach but failed. He covered his maw and gaped his eyes as he watched her tumble off all the branches and land with a thud and a cloud of debris. "Are you okay?" He called down. "I'll-"

"I'm fine!" She interrupted before he could apologetically offer therapy. "You should know by now I'm pretty durable!" Up to this point, she'd somehow managed to keep all his seed inside her, despite it making her look pregnant. Not a single drop of mess, except what came out of him after she pulled herself off his length, ended up on the floor or the wood of his home.

Lethias kept staring out his window as she got to her feet. "Are you sure, I could help?"

She stretched a bit and twisted her torso a bit as her entire body shrunk and her belly stayed the same size, a thick and steady stream of his seed escaping from between her lips to soak her inner thighs. At the same time, her wings were slowly growing again as her eyes lightly glowed. "Thanks for your help, my man! I'll catch you tomorrow!"

"Wait, aren't you supposed to help me re-sort my cards?"

"I'm sure you'll be fine! I wouldn't know what to do with them, anyway!"

In truth, Lethias just wanted her to stick around to maybe share a meal or something. He didn't actually expect her to help with the cards. This was disappointing to him, but he understood her moods and thus didn't prod further. "How long will this growth last?" He needed to know because he was too big to get out of his house without breaking something. His husband would have to come home and see him curled up on the main floor.

"You've got till morning! Earlier if you expend enough of your essence, if you get my drift." She offered a salute. "I'll see you online!" And with that, she spread her wings and leapt into the air, her womb releasing the rest of his seed in a nearby stream as she glided over it, leaving a trail behind her.

And that was it! She was satisfied for now, Lethias was left with tones of big-muscle energy and nothing to do for the rest of the evening, and both of them had plenty of opportunities in the future.

For her, it was a little like estrus, but it fluctuated daily. For all she knew, she might return later that night to help him expend some of that growth energy. For now, she had some work to do.
