With chapter 7 hitting the perquisite number of favs, I now present chapter 8!

Our protagonist is a 19 year old college student named Kaiden Wilson, a Unity Programme graduate from Vancouver British Columbia, and the odd situation in which he is put thanks to a discovery of yet more versions of earth in the rapidly expanding multiple-reality-stretching world in which this story series takes place. Unlike on many other Earths, Plateau Earth places one visiting student with seven natives. The Viddin, as they call themselves are divided into multiple categories based on species, and overworked, over-utilized has one of each.

Readers were so patient as the time progressed with Kaiden and Tral moving things forward with their date so I felt compelled to give them the right amount of time together. I present to you, my wonderful readers, an entire chapter devoted to sex. Snuggling now, with some pre-sleep talk and snuggling to follow in the next chapter which, as usual, will be posted after 25 more favs on THIS post.

As always, thank you for reading, and I appreciate all the comments and favs I receive. This story was started as an April Fool's joke but, thanks to all the support is now into its second "book". Keep up the favs and I'll keep posting more chapters! Thanks so much for your support!


The Cohen-Kline Icosahedron

Chapter 8

Tral, his head pinning Kaiden, was getting increasingly excited, rubbing his neck and beak all over the Human's front. A constant reverberating rumble was coming from the enormous Viddin, and his heavy-lidded eyes looked glazed over and drunk. Every now and again Tral would poke at Kaiden's clothing, nipping gently at the cloth as he mumbled to himself in the Viddin language "Mmm... I never realized how much these got in the way."

Snickering, Kaiden ultimately had to use both of his hands to force the huge head back so he wasn't half-covered. "Well, it's kinda hard for me to take them off if you're pinning me, you know."

Suitably chastised, Trail lifted his head up, pushing off the ground with his talons until he'd risen up sufficiently to give Kaiden room to maneuver. Going further still, the large Viddin spread his wings, the primary feathers of which brushed either wall of the wide room, and he stood up on his hind legs, creating quite the imposing figure... right until his head hit the light fixture, and he tumbled over backward with a muted exclamation of "Khwah!"

Landing with his wings and back cradled by the gigantic sleeping sofa behind him, Tral was half propped up with his elbows resting against the bed, talons almost touching the ground, and his back half hunched forward with his rump on the ground. Kaiden, who had just about sloughed off his clothes, couldn't help but laugh at the sheepish Viddin, whose nares were practically glowing red, and his 'ear tuft' feathers were pulled back in embarrassment.

Finally naked, the Human slowly crawled across the carpet toward him, and he could tell his approach was having an effect as the gryphon's member slid free of its sheath, and shot a small spray of precum into the air. The Human stopped so he could rest a hand against either of the huge Viddin's paws; even with them held relatively close together, Kaiden had to spread his arms out to do so. "Sooo... have you given any thought as to how you would like to--"

Tral blurted out his answer before Kaiden could finish. "I want you to ride me like you did with Prirn your first time with him!"

Kaiden felt his cheeks flush in surprise; despite being so self-conscious about the fact that Prirn had OBVIOUSLY talked about their time together with the rest of the Roost, the Human realized very quickly that it was to be expected, and he pushed through. "Alright... if that's what you like, but, just so you know, I'm pretty sure it won't be EXACTLY the same considering the two of you are not exactly the same size... and I--"

Tral's beak parted into the hugest grin Kaiden had recalled ever seeing from him. "I'm sure!" Apparently the Viddin's penis was just as sure, and it shot another copious geyser of precum into the air to accentuate his statement.

Kaiden scooted a little closer on his knees, his fingers gently brushing up either of Tral's paws and up to his knees; the Viddinire shuddered, eyelids fluttering as his rock hard member began to pulse rhythmically, "K-Kaiden... I--"

The gryphon's beak clamped down tightly as a powerful blast of milky fluid shot straight out of him, spattering into the ceiling a good ten feet overhead. A second geyser almost reached the ceiling, only to rain back down on the two of them; the third got a good foot or two in altitude before sloppily splattering onto the Viddin's groin. The fourth and fifth jet managed a few inches, thoroughly coating the still turgid shaft in seed.

Stopping right where he was, Kaiden glanced at the ceiling, then down at Tral's abdomen and his shaft, which didn't seem the least bit spent, and then, finally, directly at Tral's eyes, which were focused right back at him. The Viddin blinked once, his nares even redder. "If I hadn't seen it for myself, I would have thought you hadn't used your Jiyjah in a week."

The gryphon worked his beak several times before softly grinding it then answered. "Um... Kaiden'huu... you... have some on your--" Rather than finish the statement, Tral leaned forward, bending his body almost in half so he could lick the young man's ear. Tral pulled back, a thin string of semen coming away with the beak. "There. Got it. Sorry..."

Kaiden didn't stop smiling. "You know... I just can't see how some people could be offended by a partner who finishes so quickly. It's more a compliment than anything else."

The Viddin blinked, returning to laying back against his bed as he alternated between looking at Kaiden and down between his own legs, then back to Kaiden. "If you keep being you and keep doing what you are doing then I look forward to 'complimenting' you a lot more."

The Human pushed his leg out so he could catch his uniform bottoms with a foot and then brought it closer by withdrawing his leg. He slid a hand into the pocket and pulled out a bottle of Xys he'd kept at the ready. "If you're laying like that you won't be able to do very much... you okay if I'm in control, Tral?"

Tral waggled his beak up and down in an obvious overly enthusiastic imitation of a human nod, followed by a squeaked confirmation in the Viddin language. "Yeah."

Kaiden scooted up until he was situated in the space between the gryphon's legs; he could feel the immense amount of bodyheat coming off of Tral's throbbing organ, which was easily as big around as his forearm. The young man popped the lid on the Xys and began pouring it into his palm. "I'm... gonna put some of this on you if you're ready..."

The Viddinire practically crooned. "More than ready... Takket'im."

Pouring out a copious amount into one hand, Kaiden felt the tell-tale tingle and he set the bottle aside so he could coat both of his hands. Once his fingers were bathed in the stuff he went to the tip of Tral's very respectable length and pressed both his palms to it. Touching thumb-to-thumb and fingers-to-fingers, Kaiden slid his digits down the tapered length; about two thirds of the way down they no longer touched, but he was more concerned with the way his companion suddenly bucked, squawking out, and the young man was forced to lower his head as fresh strings of semen rained down on them.

Kaiden continued gently working the Xys against the gryphon's length even as Tral came down off his high. The Human was perfectly happy to chide his classmate... just a little. "Seems like SOMEONE is excited. You really want this don't you, Tral?"

The Viddin stared at him with verve as he stated with the same kind of intensity as Vetlyk usually reserved for his more take-charge moments. "More than I have ever wanted anything, Takket'im."

Feeling himself blush at the blatant stroke to his ego, Kaiden continued slowly spreading the Xys around on the Viddin's ample erection while he retrieved the Xys container and dipped his fingers into it, curling them so he could take more out. Leaning forward, he pressed more of his body against Tral's thick cock. At a better angle for continuing to ready himself, Kaiden slid two fingers into his own opening. Finding next to no resistance, the young man worked his digits around, making certain he was generously spreading more Xys.

Tral's voice was shaky as he spoke in English. "You... are a better dancer than you give yourself credit for, Kaiden."

Only once his companion called his attention to it did Kaiden realize that, as he'd been working his fingers into his opening, the rest of his body had moved as well, and had been caressing the gryphon's so-sensitive shaft. Feeling himself blush anew, the Human smiled; a sudden idea entered his mind, and he met Tral's gaze. "Well... you were a really good teacher, Tralyn... you helped me feel the rhythm through you."

The Viddin's member pulsed tellingly when Kaiden called him by his full name, and the Viddin let out a long, shaky breath as he almost melted into the bed. "You are so good to me, Kaiden. You know, you do not HAVE to do this, but you do it anyway... I am so glad that you are here with me now and--"

Kaiden silenced him by wrapping both arms around the fleshy pole which stuck straight up from the gryphon's crotch, and made Tral suck in a breath by moving his entire body against it. "I'm here because I WANT to be, Tral... I know I don't have to be... now stop trying to convince me not to do this with you and just leave it at 'thank you'."

Undulating his entire body against Tral's shaft, Kaiden laughed inwardly, imagining the thought of a stripper pole-dancing with a Viddinire's cock. Tral, however, seemed to be focused only on the immediate moment; his hip began to vibrate and his paws clenched and unclenched, talons tightly gripping bedding as he began to murmur"Thankyouthankyouthankyouthankyou." and, a moment later, Kaiden was treated to yet another eruption, and was showered with fresh streams of ejaculate. There was no doubt about it; their night together was going to be a messy one in every stretch of the imagination... and Kaiden didn't find himself minding.

The young man brushed at a lengthy line of slick gryphon spunk on his shoulder and smirked, looking down at the Viddin beneath him. "Doing alright?"

Tral's eyes were glazed over and his sword-like tongue hung limply from the side of his beak. "I am in Triech."

Kaiden chuckled, crawling further up his companion's abdomen, sternum, then chest so he could rub his face into Tral's feathery neck and offer a kiss to the side of the gryphon's beak. His movement, he realized, also made it easier for Zithing to join them, and the young man only realized it when he felt two scaled talons on either side of his rump; a moment later, a slick, serpentine tongue wormed it way easily into him.

Tral pulled away from Kaiden for a moment to squawk at the Ilsit Drone. "Be gentle with him, Zithing."

Kaiden smirked at that, pressing a hand against the side of the Viddinire's beak to bring the big gryphon's attention back to him. "I'm fine, Tral... HE'S fine. Zithing knows what he's doing."

The Ilsit spoke even as his tongue was worming its way around within the Human, slathering Xys all over his insides. "Y hyvy hyd plynty yf pryctycy wyth Kydyn."

It was a rather forward statement, but the Ilsit wasn't wrong. "Not THAT much practice, Zithing. Don't get ahead of--- OOHHG!" In the middle of chastising the Drone, Kaiden's objection was stalled when the wiley Ilsit's tongue hit him just right and the Human's voice left him due to the sensation; he leaked a jet of precum onto Tral's chest.

Tral's usually goofy smile turned lustful as he crooned "I want to make you make that sound, Kaiden..."

Returning his attention to the Viddin, Kaiden felt his cheeks redden. "We'll work on that together... and I want to make sure that you're not just coating the ceiling and the floor with all of that... you know."

The enormous gryphon's grin became even more lecherous, and he offered a rather crass way of saying it in his native tongue. "You mean all this kihk? You really want it in you, do you, my little Zfielt hen?"

Despite the obvious attempt at dirty talk, the way Tral's nares reddened immeasurably and the fur around his beak puffed up revealed the extreme amount of bashfulness he must have felt at saying the words. Kaiden patiently caressed the gryphon's chest where feathers met fur before slowly sliding back down the huge body beneath him, one leg on either side of the trunk-like torso. "Tral... you don't have to be the 'head-cock-of-the-aerie'. Just be you... that's the Viddin I love."

Every last feather on Tral's head and face stood up at that and his eyes widened, pupils turning into deep pools of black as his beak went slack. The Viddin't beak worked several times before a single word squeaked out. "Love?"

Even though Kaiden felt himself blushing, he managed to keep the embarrassment out of his smile; he knew it was true. "Tral... you are a warm, thoughtful, and caring Viddin. You are patient with me, and gentle. You are kind, considerate, and willing to sacrifice for the Roost... even sometimes when I wish you wouldn't. I like spending time with you. I trust you. I feel like my life is better for having you in it. Yes, Tralyn, you big, silly goof... I love you."

An almost drunk-grin spread across the gryphon's beak. "Nobody has ever said they loved me in a way that I felt like I could believe them..." A moment later he started crying.

Kaiden didn't bother counting the amount of time he spent embracing the Viddin with his entire body. Their time together had started with the promise of something messy and sexual and physically intimate but, despite the gryphon's 'explosive' start, it had, in the matter of seconds, changed into something emotionally messy, and emotionally intimate. He felt each shuddering breath of his companion, and each sniffle through the huge lungs against which he lay.

Ultimately, however, what he really felt was a powerful hug that almost threatened to break bones. A beak brushed at the top of his head, which was barely poking out from beneath the ample-sized, feathery forelegs. "I've never said it to anyone but my sire, Kaiden Wilson... but--" Despite the many times he'd stated that he he hated how he sounded speaking Human languages, Tral spoke the words in English. "I love you too."

From off to the side, Zithing sat on a small pillow, staring at the two with his thin, pink, scaleless member outside of its slit, but relatively flaccid in his talon. "Yyy twy lyvy yychythyr. Gyyd. Yry yyy gyyng ty fyck nyw?"

Tral shot a deathgaze at the lizard. "Just for that, you do NOT get to watch."

The Drone issued out a rapid-fire objection in Ilsit, far too fast for Kaiden to follow but, even as he objected, Zithing picked up his pillow and stormed his way off into the closet. He slammed the sliding door in an obvious show of rage but, Kaiden also saw that the door remained opened a crack, and a reptilian eye was peeking out from within.

An exasperating sigh escaping his beak, Tral flopped his head back down onto his bed and groaned, covering his face with his talons. "I am sorry, Kaiden... I think I ruined the evening..."

Gently caressing his companion's furry chest, the Human spoke calmly and softly. "Why would you say that, Tral? You haven't ruined anything."

The large Viddin was quiet for several seconds, his feathers alternating between puffing up and smoothing out. When he spoke, it was more of a statement than an answer. "Usually the hens who want to mate with me expect me to be a perfect Shooshuh star who can ride them all night and has his life in order. What is more sexy than that?"

Smiling, Kaiden continued to gently stroke his classmate's chest, then sternum, then abdomen as he slid down Tral's lengthy body, not stopping until he felt the skin of his bare rump press against the firm, slick, furless flesh of the Viddin's member. Still looking Tral in the eye, the young man said only "You. Right now. Like this. Honest, and genuine. I think that's very sexy."

The Viddinire's beak moved several times before a voice came out. When it did, it was soft... nearly demure, and full of honesty. "I am not used to being like this with someone-- with anyone. I... I like how you make me feel, Kaiden... even if the hens wouldn't find it attractive."

Winking, Kaiden slowly stood, legs splayed wide so he could have a foot on the ground on either side of Tral's broad hips. "Well, it's a good thing you don't have to worry about what they like... I find you plenty attractive."

Tral blinked the dampness away from his eyes and his eyelids lowered over them as a goofy expression spread across his beak. "I find you very attractive too, Kaiden... especially like you are now."

Kaiden felt his cheeks flush as he assessed his own situation; he certainly didn't feel very sexy, so perhaps that made them even. "Well... just you wait... presuming you still want to try this?"

While waiting for an answer, the young man clarified the plan, reaching back behind himself to gently stroke the still-hard shaft resting against his back. Tral very quickly rapid-clicked his beak in ascent. "Yes. Oh yes. Very much yes. I do. I really do.... but... just remember: you can stop at any time if you--"

Before he could second guess himself, and before Tral could raise any more objections, Kaiden raised into the air on his tip toes, aiming the pointed tip of his companion's member, and then, in one, smooth motion, lowered himself down, taking several centimeters into himself in one go. Despite the fact that the Viddin's organ was easily close to a meter in length, the young man was surprised how easily it slipped in; thankfully it was tapered, and so the going was easy... to start.

The issue was complicated somewhat when Tral's erection began pulsing with more force than just beating in time with his heart. A second later, Kaiden was up on his tip toes again as a torrent of Viddin semen washed into him. Tral's breath had caught and the gryphon's body shook, a tight groan slowly wheezing out of his beak as the Human's insides churned with the furious blasts of thick cum.

Kaiden waited until Tral's body went limp again, the massive Viddin panting happily before the Human started moving again against the only part of the gryphon that wasn't flaccid, taking in several more centimeters. Eventually, the young man paused, adjusting his footing, which was awkward considering how wide Tral's hips were compared to his. Letting out a breath, the Human looked to his glaze-eyed companion. "I must be most of the way by now."

He heard Tral's tail thrash against the floor and his companion smiled happily up at him. "You are making amazing progress, Takket... almost half way. Many of the hens I have been with have barely made that."

Kaiden had a feeling his eyes were going to bulge out of their sockets. "HALF?!"

Despite the still-obvious hunger present in his eyes, Tral's tone was calm and even. "Kaiden... Takket... you have done so well. If you need to stop--"

The Human shook his head. "I can go further... that's what the Xys is for."

The Viddin's pupils focused on him. "You... can stop there, if it's uncomfortable. It still feels wonderful, Takket. I am longer than Zithing's tongue, so there may be parts of you that are not as exposed to Xys as the rest..."

A voice barked loudly from the closet in very clear, very precise English angrily. "I am good at what I do! He will be fine!"

Willing to trust in Zithing's opinion, and giving way to his own eagerness and excitement, Kaiden pushed forward, bending his legs as much as they could go considering the situation. Tral hiccuped his breath in response, hips shaking slightly as he murmured something about his wonderful Human. Kaiden, on the other hand, knew he'd have to readjust his position. Rotating slightly, he shivered as he felt the Viddin's penal barbs tickle his insides while he moved so he could fold one leg, pressing his shin against Tral's inner thigh, and then did the same with his other. "Is this alright?"

Tral's eyes rolled back in his head. "K-Kaiden... please... do not stop. Whatever you want to do... anything... j-just... k-keep going!"

Smiling at his partner's enthusiasm, Kaiden was able to use his better position to fold his legs, lowering himself down further, and, as he felt the deepest parts of him tickled by the enormous length, the Human's senses were overloaded as another geyser of Viddin seed was emptied into him, the thick shaft impaling him pulsing with each blast. Tral had gripped his bedding with either talon, digging his claws into the cloth as he clenched down, stiffling a loud screech as his newest eruption was the strongest yet... but Kaiden was still not yet done, and so the Human soldiered on.

The young man's insides were so filled that they were overflowing; every centimeter of Viddin flesh that entered him caused fluids to leak out, spraying in the infinitesimally small space between Tral's erection and Kaiden's tight opening. At some point, the Human realized he had no space left in him and yet, somehow there was still more-- until, at long last, he came to rest on Tral's groin, and the fur on the gryphon's grapefruit sized testicles tickled his rump. Only at that point did he let out a held breath. "Got it."

Tral's head had craned upward so he could gaze down his body at Kaiden and the Human felt his cheeks burn as the Viddin's eyes zeroed in on him, pupils dilating into huge pools as he crooned softly. "I cannot ever recall seeing anything sexier than you... right now."

The Human felt his flush deepen even more, and he absently ran one hand across his abdomen, as if expecting to feel the bulge, or sense the outline of the huge organ within him. Using his other hand to steady himself in place on his lover's lap, the young man offered "I... feel a little more foolish than sexy to be honest."

The Viddinire sqawked indignantly, but his response held a hint of humor with the reproach. "I do not appreciate it when you call my mate foolish."

Despite Tral's usual slow-on-the-update wit, the big goof was surprisingly piquant with his response, and it left Kaiden smiling. "Your mate, huh?"

It was the gryphon's turn to blush, and his nares reddened noticeably. "Well... if you will have me, Takket."

The young man laughed, rubbing his abdomen again. "I'm 'having' you right now."

Tral's resposne was a soft, low rumble-- it was a soothing sound, mixed with the hungering growl of great desire. "Kaiden-- Takket... you have taken more of me than most hens... I am happy to give you all of me."

Kaiden flexed his legs just a little, wincing as the massive tool within him shifted, and he shuddered as he felt Tral's penal spines stroke his insides. "Nhgh... more than your 'kihk', you mean?"

The Viddin let out an indignant squawk, followed by a shudder of his own, and Kaiden felt the gryphon control a reflexive hip buck. "I mean my kur, Kaiden. You have my heart. I want you to be my mate. I want to give you my chicks, and I want us to be together."

Despite himself, and the numerous concerns that came with it, Kaiden couldn't object. "I would like that, Tral."

Not leaving it simply up to words, the Human drew even further off of Tral's enormous erection. He felt the tingling sensation of his textured flesh moving in the right way to get a response from him, and several rivulets of precum leaked from him and fell down onto the Viddin's hips. The gryphon, in the meantime, simply closed his eyes, letting out a pleased sigh. Steeling himself, Kaiden let gravity bring their hips back together, controlling his descent only to the point that he wouldn't hurt himself.

The response from his classmate was instantaneous. Letting out a squawk of surprise, Tral's talons dug into the bed and his paws scrambled for purchase on the carpet, hips quivering as he objected "Kaiden! That-- that was almost too much... I... I almost--"

Starting to pant, Kaiden was already rising up again, starting to feel the sensations dig deep into him and draw him ever closer to the precipice of no return. "Just-- almost done, Tral... you're... doing great."

The Viddinire blushed again, face feathers puffing up. "You are doing almost everything... I am just trying not to hurt you."

Kaiden looked down at his lover through half-lidded eyes as he began to feel the pressure grow; it rose exponentially on his next down stroke. "You haven't, Tral. You're... perfect."

Losing control of himself, the young man picked up speed, lowering again only to rise a moment later, the massive shaft emptying out of him only to fill him back up, those playful, delectable barbs working him just as hard as he was working Tral. Kaiden lasted two more complete sets before his legs gave out and he saw stars as he slammed back down, his hips meeting the Viddin's as he arched his back, and he came, probaby the hardest he had in his whole life. Tral, of course, was not passive.

Gripping handfuls of fur, Kaiden was almost pushed up several centimeters on the gryphon's shaft by the newest geyser that erupted within him. Even as his insides tried to milk Tral for all he was worth, the Viddin's huge member pulsed and throbbed as it emptied yet another load into him. Even as most of it came cascading back out, Kaiden didn't mind, pushed to an even higher plateau as he felt his senses overtaken as the euphoria of warmth overtake him. As he rode out his orgasm, the sensations slowly faded and, thereafter, so too did his stamina. Spent, he collapsed onto his lover, the sound of a strangled, muffled screech echoing from the closet, accompanied by the frenzied objection in Ilsit that "it's on the walls!". The Human ignored it.

Kaiden was practically convinced he was burping up the taste of Viddin semen, though the more rational side of his mind reminded him that he was laying face down on a gryphon abdomen already smothered in it. The young man told his brain to shut up, simply basking in the moment, and loving it. A talon slowly wrapped around either bicep and pulled him upward along the furry body.

At first, Kaiden was going to object since he still reveled the feel of being filled to overflowing but, despite being drawn almost a meter up the huge Vidden, he still had plenty inside him and, he realized, Tral was still leaking, and it only made room for more. Once he had caught his breath, the Human noted "I don't think I've ever been this full."

Tral was able to get his beak down low enough to ruffle Kaiden's hair. "I do not think I have ever been this happy."

With both lovers satisfied, the sex was done for the night... but the snuggling had only just begun.
