Just Two Weeks: Changes

Mark had slept in late after the sexual ordeal he had gone through the night before. The teen fox's normally slender, cream-colored belly was swollen visibly with the forms of four semi-solid, softball sized eggs. His muzzle, cheeks and neck were glazed over with a thick layer of Smith's half-dried wyvern cum. The biggest mess of all was centered under his tail, where a large mass of white sexual fluids had hardened into a sizable plug, as wide as his wrist. Marra set it deep inside his gut, and as she pulled out a great deal of spillover had run down down behind his balls, where it solidified and bonded with his fur. The other end of the thick natural tether was affixed to fast to the floor in a messy pool of white that was a mix of wyvern cum, birthing fluids, and the special protein that made up the cord.

Though, the fox was not about to go anywhere, instead he slept soundly. His head rested comfortably atop Smith's warm, firm inner thigh, face toward the wyvern's large, reptilian bird form. The feral male had curled around his small furred mate possessively and tucked his large head under that cum-streaked fuzzy brush of a tail in his sleep. His warm breath poured rhythmically back and forth through the thick, mussed up fur.

The much larger female wyvern had fallen asleep curled around the other side of the vulpine; her tail behind his head, egg-heavy belly settled gently against his back. Her leg supported Mark's body off the ground, and kept the todd warm and cozy through the night.

Marra was the first to wake, though she did not stir, the large, intelligent mother was intent to let her surrogate fox rest for as long as he could. She knew he needed it. Rather she just laid there and rested contently, still filled with pride and joy.

In due time Mark was the next to move. He craned his head back and resettled it atop its makeshift pillow of powerful muscle. His soft cheek-fur brushed Smith's inner thigh as he stirred, his mind still lost to dreams. The winged reptile moved and twitched his leg, then tucked his head in closer to the fox's sex-stained rump. The shift practically buried his nose in the source of all those drying musky fluids and they quickly had a big effect on the feral minded creature.

With each long , slow breath his genital slit welled up and moistened visibly. His long, tapered length stirred within his body. With a soft, near inaudible squelch the scales parted and revealed the soft pink flesh hidden within. Along with it was the beginning of a small dribble of fluid that trickled down his smooth scales to the floor. His just barely visible slit parted more with every long breath, and soon the thumb-wide tip of his length poked its way free.

His musky, tapered shaft inched unerringly toward Mark's muzzle with each slow beat of its owner's strong heart. Little dribbles of pre leaked from the tip with each pulse of life and left glistening trails down his muscular, red thigh.

Soon the organ brushed across the end of the fox's muzzle. The rich smell of male pressed right against his nose sent an electric thrill through his body and pulled the sleepy boy a little closer to reality. The scent clouded his already sleep-sodden senses and he pulled his muzzle open in a sleepy, yawning-moan. That shaft emerged ever onward, past the boy's parted lips, but not quite in contact with anything. His hot breath ebbed and flowed over its slick surface like waves, and soon made it twitch with a spurt of preseed, which reinforced that wonderful, pheromone laden scent. Mark unconsciously closed his muzzle over the bestial length and licked out at it sleepily.

The rich flavor and moisture on his maw alerted the fox's foggy mind and woke him enough to realize that something was different from his usual wake-up routine. He blinked his eyes open just slightly in the dimly lit room. The only light that reached them was from behind the doors of the pens across the room the wyverns had entered from the night before; though they were out of the boy's view, it was enough illumination to see by. The one thing that dominated his vision was the massive shaft that continued to expand, right into his muzzle. Memories flooded back to him with the next jet of pre, but he did his best not to move and risk waking the two creatures on either side of him.

With utmost care not to alert Smith, he pulled his head away, but only managed a couple inches before the back of his head pressed against Marra's tail. Smith's cock twitched with another jet of pre right over the roof and tongue of the boy's mouth. In order to keep his muzzle clear he swallowed some of the thick, musky fluid, and the movement only enticed more from its source. He soon was faced with the choice between disturbing the two massive sleeping creatures or leave his head there and swallow the fluid. He tried to let the white cream ooze just out of his muzzle, but as time passed, and more was pumped into his mouth, an urge to swallow built inside him.

His stomach gurgled and called out for more of that life drink, which the growing length supplied in copious amounts. Soon it all but filled his maw and pinned him to the thick, muscular tail behind his head, with the tip right at the back of his throat. He managed breath between the great gobs of goo that leapt from it.

By now, Smith had woken from the pleasure of Mark's warm muzzle around his meaty shaft. He began to rock his hips sleepily back and forth, which drew his shaft out of the fox's muzzle a few thankful inches, before he rocked forward, filling the boy's mouth even more. Mark drew both paws up and stabilized the erratic shaft. To have his teeth graze the wyvern's length was the last thing he wanted to happen, as he did not know how it would react. The jets of pre spurted out heavier and more frequently with every passing moment.

The large reptile loved this sort of wake up call. A rolling rumble built in his chest as his movements became more erratic. His cock bounced Mark's head off Marra's tail several times as he thrust repeatedly, until he let out a loud cry of pleasure. Large talons gripped at the air as he dug his snout under the fox's tail heavily. His wings fluttered, then tensed along with the rest of his body. With a final push, he drove his length right to the back of his small mate's throat and came. Hot torrents of thick jism blasted straight down the boy's gullet into his belly. He rolled his hips again slightly with each of the five-second-long, heavy jets, then pulled his shaft free.

Mark sputtered and moaned as he panted for air. Some of the lustful feelings from last night began to return to him. It was not just the venom of the wyvern that fueled his libido; the cum itself acted as a stimulant in that respect. Smith pulled away once the thrill of orgasm had mostly faded from his body. He moved to stand; his shaft left a messy trail on his thigh and the ground while it dragged away from the todd's face.

The male stretched his wings and legs out in an almost cat-like fashion and then turned to face the messy furred fox. With little warning, he leaned in and lapped over Mark's muzzle, licking up the still fresh cum that had just been deposited there. Mark closed his eyes, mouth open while he continued to pant. Smith took the opportunity and lashed his tongue right into the dazed fox's mouth. Finally, once he felt satisfied he turned and trotted outside with a bounce in his step.

As he crossed the threshold he spread his wings in a long stretch, then thrust them down as he jumped out of sight. A few moments later the doors slid shut and the internal track lighting bloomed to life. They filled the room with a bright, though not blinding white light. Mark closed his eyes for a few moments to let them adjust. Across the room he heard a click, but Marra made for a poor window and blocked his view of Dr. Mertezi as the middle aged rabbit stepped through the door.

The doctor carried a brown leather satchel across his shoulder that hung at his side. He wore his professional looking gray pants, shirt and long lab coat, but no shoes. The first thing that tipped Mark off to the lapin's presence was the sight of a black-furred paw. It ran down along Marra's still egg-heavy side toward her tail. It was then the doctor stepped into view to the boy. Mark tried to sit up, but the huge mass under his tail immediately made itself known and kept him prone from the surprise; a soft gasp jumped from the vulp's muzzle.

Mertezi knelt beside the fox and smiled. "How are you feeling this morning? Any soreness, Dizziness, numbness?" As he spoke he retrieved a device from his bag. It looked rather like a palmtop computer with a small tube attached to the top. The doctor disconnected the tube and drew it across Mark's belly then chest, all the while he watched the screen.

Mark shivered a little in surprise a the treatment, but endured it. "Umm, I'm kinda sore I suppose." He groaned and put a paw on his swollen stomach. He did not want to admit it, but that night had really felt incredible, and continued to feel good, even now. The doctor nodded and tapped at the screen a few times as he took other little measurements of his vital statistics. "Seems you're quite healthy in fact. It looks like your body is getting the nutrients it needs from Smith's semen. Excellent, everything is going flawlessly!"As he spoke he walked around Mark slowly.

The ground was still warm from Smith's presence. He stepped absentmindedly in some of the musky cream on the floor before he leaned over the inspect the large plug Marra had left at the fox's sphincter for a few moments.

Mark had trouble forming words as the effects of Smith's load in his belly grew. His body tingled with electricity and he soon had to suppress a little moan. The rabbit drew the device back over the form of each individual egg now. "The wyrmlets are already developing well, though it looks like we already have a favorite in this egg!" His face spread into a cheery smile as he showed the palmtop to the vulpine.

Four off-spherical objects were displayed on the screen that he correctly guessed were the eggs. Inside each of them was a small snake-like object. One of them looked much larger than the rest and filled a bit more of its eggshell home. A look of mixed curiosity and confusion spread over Mark's face.

"But... why me?" He closed his eyes and shivered as another little euphoric rush flowed through his body.

"Why you?" Dr. Mertezi paused and considered his words. "You were most appropriate for the opportunity of course, especially after managing to taking to Aita so well. The Institute was reluctant to even have her breed because she's just so large." The rabbit chuckled, "Though I admit, that left her more than a little pent up, so I can't hold it against my baby." He saw the look of skepticism on Mark's face and continued. "You see, my boy, Wyverns are a dying species. Just about extinct in the wild in fact. This area is a preservation, so they're safe.

"One of this center's primary goals is the survival of rare and unusual species. I've been planning this very event for months. Now that it's finally coming to fruition," Dr. Mertezi closed his eyes and almost shivered with excitement, "it is an incredible opportunity. Yet so far there has not been a single successful breeding in captivity. You see, the males are terrifically territorial, and they don't like the smell of any other males in the area. If they do scent one, they get... a little violent." Mark's eyes went wide," Not to worry though. Last night I sprayed you on the way in with the same pheromones you're now making on your own." Without missing a beat he slipped a paw down and caressed Mark's plump sheath with his plush-soft fingertips.

Though the fox was well aware of the erotic rush that filled his body caused the wyvern's seed, he hadn't noticed that he had grown hard while he'd been talking. His black, rubber-coated length half protruded in front of his belly and twitched gently in the air. Though still as slick as ever, not even a drop of fluid emerged from the slitted tip. In fact, all seminal fluid had been blocked at his prostate by the strange black covering.

"Tell me, is this as sensitive as yesterday?" Mark moaned softly and arched his hips. The feeling of Dr. Mertezi's talented paw was not overwhelming like it was when it was put on, rather it just caused him to tense up and moan loudly, then hump forward involuntarily.

The rabbit kept up his ministrations; his fingers danced over his subject's length. "Good good, it has set just like I hoped." His soft fingers encircled the boy's twitching member and stroked it slowly up and down, much to both their delights. In just a few passes it had grown near rock hard. His knot emerged from within its confining home and pulsed in the warm embrace of the doctors digits. He set his pad on the floor, then brought his other paw in. With a practiced motion the lapin slipped his fingers and thumb tight in front of Mark's knot, and popped forward over it. The fox cried out again as his hips quivered forward into the simulated tie.

With his ever present smile he leaned in close, nose nearly touching the tip and took a long, deep whiff. "Good, good. The scent has not changed since yesterday, and since Smith didn't seem to find anything wrong, that means it's blocking your semen flawlessly," Mark's eyes fluttered open as he looked down. The older rabbit's tongue flick out and dragged it up the side of the boy's ebony black shaft to the tip, which he playfully encircled with his lips and bobbed back down a few times. He pulled off slowly with a pop and sampled the flavor in his mouth, then noted it down on his pad computer.

"Now, back to what I was saying earlier." He slipped the pad back into his bag, "You're the first step in an effort to repopulate the species. Your name will go down in history as father... or perhaps mother," he said with a pat to the Mark's belly, "to the first clutch of wyverns years!" The excitement on the doctor's face was unmistakable.

Mark was bewildered by all the information, and feelings surging through his body wasn't letting him process it all. "I guess that's... okay." A little semblance of sense stayed with him, "but, I've never seen anything in the world like, well..." He looked back at Marra, "that." She thumped him with her tail enough to get his attention. "Ow, hey!"

"Aw, he didn't mean it that way, girl." Dr. Mertezi pet down the large female's flank and turned his attention to Mark, "Female wyverns are remarkably smart, and sensitive, it's the big reason males were the ones hunted to near extinction rather than them. Marra here understands common English fluently, in fact."

"Wait, but I've never seen them before." The teen looked puzzled. "Well, what the best way I can put this. They're from... not so much another planet, closer to another plane of reality." The doctor replied in a nonchalant tone as he exchanged devices for an eye examination tool. "if you would look at my left ear please."

He leaned in close and then looked through the magnifier and shined a light into the fox's eye, where he spotted a little discoloration. "Hmm, very interesting, I'll have to keep an eye on that," was the only remark made by Mertezi as he noted down more information in his palmtop. The todd put a paw to his eye and looked puzzled for a moment, and was about to speak, when the doctor stood and looked toward the entrance Smith had exited through. "Well, I really must be going to examine this data. Oh! I nearly forgot." With a quick motion the rabbit scooped through his bag, "ah ha! I'll need you to put this on."

In the doctor's hand when he pulled it out was a finely made black leather collar. It had no buckles or straps, and one ring just at the midpoint with a tag that read in two lines 'Subject Red' The fox blinked and pulled away slightly as he saw it, "A collar? Wait what? Why?" The older lapin handed it down to the boy. "To keep you safe of course. Inside that is a beacon for within The Garden, as well as a simple health monitor. It will alert if something is wrong, and even alert me when you go into labor. Clever little device, I'd say."

Mark's eyes went wide with a flurry of thoughts as his paws darted to the swells in his belly. His ears perked high and his fur bristled. "Labor?"

A soft, chuckle filled the doctor's chest, "But of course," he replied offhandedly, "How else do you suppose they're coming out? Go ahead, on with it. Or if you prefer, I can always put it on for you." The fox knew full well Dr. Mertezi had the means to get it on, whether he liked it or not, so he opted not to tempt fate and put the collar on.

The rabbit then spoke up. "Ah, good. Looks rather handsome on you, I should say. Now, you'll find you won't be able to take it off yourself. Just a safety measure of course. If we were to think you were in the wrong place, I couldn't come to your aid if something were to go wrong, you see."

"What could go wrong?" Mark asked out of concern and blincked a little wearily, his mind was still hazy from the odd euphoria that pulsed through him in gentle, slow waves.

"Exactly!" Was the lapin's bewildering reply before he looked down and pet over Marra's side. "Could you clean up the boy and take him out for a little walk of the grounds, hun? I'm sure both of you could use the stretch after that show last night." The wyvern's only response was a little grunt. Mertezi smiled and turned back in the direction he came from. "Enjoy yourself out there, it's really beautiful this time of year."

Mark slid to all fours with a heavy groan as Marra climbed to her feet and gave her bulky form a good stretch. The form of many unfertilized eggs could be made out in her belly, though they were not nearly as apparent the as the four in the smaller fox. With a little shake from head to tail. She saw Mark look up to her with a look of worry. Her broad head swooped down to Mark's level and sniffed over his form, causing him to shift nervously. After a few long, hot breaths through the fur of his chest she began to lick out at messy fur repeatedly.

At first the fox was hesitant, but the rhythmic lapping soon lulled Mark into a contented state. He closed his eyes and smiled, then spread his legs more, already eager for more. The feeling of the dexterous muscle, combined with the almost narcotic effect of Smith's seed in his belly sent tingles through his body with each stroke. It coiled entirely around his upper arm, and slithered down his side. The rhythmic strokes over his sensitive form soon drew soft moans from the fox's muzzle. Her licking continued down his back.

As her tongue drew to his butt; he arched his body and continued that curve up along his flagged behind him. He pushed up more onto his knees, and he leaned forward in an attempt to arch further into the grooming. The fox's ascent was stopped abruptly by a very firm tug inside his rear end, which caused him to moan sharply. The off white plug in his rear kept him held in place.

Marra's muzzle soon dipped under Mark's tail and preened around the plug. With utmost care she nipped at her previous night's handiwork just a couple inches from the ground. Her fangs were each as big as the fox's finger, so they made short work of the goo. As it separated from the ground the half still lodged within him retracted a few inches and bounced against his prostate. Again he moaned as she dipped her snout under his butt and gave him a good push onto his knees. He squirmed and groaned more when she went back to licking at the thickly matted fur around the fox's butt and thighs until it too was mostly free of cum.

By the time he was clean he had settled his head on the floor. His knees supported him over his belly, and kept his ass high in the air. He had his tail curled over his back. A little look of bliss had long since melted the fox's face into a silly grin. His rubber-coated cocktip had drawn out and pressed against his swollen belly. As the wet fur rubbed over his shaft he moaned out and rocked his hips, humping it forward again. This let it swing free and bounced it against the solidified forms of a pair of eggs.

All too soon for the fox, Marra pulled away, satisfied with her work. She stood and took a look around the room. Dr. Mertezi stood a few feet away by the door. He watched the entirety of the display, and his obvious approval showed in the tent of his trousers. She took a step toward the door to The Garden, then flicked her long tail around and gave Mark a bump to get his attention. The teen's eyes fluttered open and he looked wearily up at her. She gave him a motion to follow with her head and chirped, then walked toward the door a few steps. She stopped and looked back to see if he had gotten the hint. He looked a little puzzled for a moment and turned to the doctor to say something, but he just motioned him to follow her as well.

"Go on, you could use the fresh air. Been cooped up inside for days now. Stretch out, get some sun on your fur. Oh, just be sure to stick to the paths. Any place you shouldn't go into is bordered in red." He smiled his warm smile, then stepped through the doorway. It closed before Mark had a chance to get a word in edgewise.

The fox felt a little defeated. There was nowhere else to go, and the sunlight he saw outside did look more inviting than the room he currently sat. With a grunt of efforts he pushed to his feet and wobbled. His heavy belly threw him off balance though with a little effort, and his tail stretched far behind him, he found a reasonable way to stand mostly upright.

As he started after Marra, she turned back around and led him out through the tall door. He planned each step carefully, not yet used to his new center of balance. Eventually he made his way outside beside the wyvern who had waited for him. The sun was glaring to his eyes. Long since had they grown accustomed to the artificial light. As they adjusted he took stock of his surroundings.

Before them was a mile wide, lush valley. In all directions he looked the horizon was hidden by hillsides and forestry. The sun shed light from just over the hillside in the distance in front of him. Its warm rays soothed his body and began the process of drying his fur. The ground around them was covered in thick, green, tough lichen. It gave only slightly to pressure, and looked to form a wide path toward a small lake downhill. Small bee-like insects buzzed around from plant to plant harmlessly.

On either side of the trail were plants, most unlike any he had ever seen. While there were things like ferns, others were much more strange. Long blue vines with bulbous growths at even intervals on either side grew near straight toward the sun, perfectly rigid in the gentle breeze. On the other side a tangled patch of yellow vines that could pass as a mass of snakes at first glance. Another patch of land contained a huge spire of pearlescent choral. The hollow core seemed to be filled with clear sap, and caught the light in such a way that caused the whole tower to glow from within.

Marra looked again at Mark, then walked down the path to the shoreline, wings tucked against her sides. The fox followed her after a hesitant moment, careful to avoid the long tail outstretched behind her gravid belly.

In a few minute's walk they reached the shore of the crystal clear lake just at the bottom of the short hill. A layer of mist still floated above it, yet to be chased away by the sun. The wyvern wasted little time; once there she waded a few meters into the water until her lower half had settled below the foggy surface. Water splashed about while she dipped her head in a few times. Here she paused and looked over to Mark, who stood timidly at the water's edge.

A moment of clarity met the fox's mind as he made eye contact. He looked down, then tipped a toe cautiously into the water. Warmth greeted it, rather than the bitter cold of snow runoff, much to his surprise. With his uncertainty melted he strode out toward the wyvern; ripples danced out from him and met opposing waves from Marra's bathing. The fox stopped just as the warm liquid engulfed his sheath-tip. A broad smile grew on his face and he let himself sink down to his neck in the steamy lake.

Even with all that had happened to him, right here, right now he felt at peace. His fur floated up weightlessly and released its grip on the cum that had stuck in place even after his earlier tongue bath. It left a misty cloud around him for a short time, but a gentle current soon swept it away.

With his attention diverted, Mark did not notice when his large birthing partner lifted her long, stiff tail from under the surface. He looked over just as the wyvern's underbelly left the lake's warm caress in a shower of water. At first he thought the motion might simply be a morning stretch, but that notion was shattered by a line of yellow-tinted urine that streamed from between her legs. Though caught off guard, the intimate encounter the previous night was still fresh in his mind, so he was little phased by the sight. It even served to remind him that his own bladder had not been emptied for an uncomfortably long time. By now it was full to bursting, and demanded release.

The near constant state of half-arousal, and the black, rubber-like device that coated his foxhood had ensured nothing at all escaped from that particular passage for about a day now. He turned away from the female and looked toward the sky in a bid to relax and let go. Had he watched Marra just a moment longer, he might have seen numerous vines that swarmed around the point the wyvern's stream pattered into the lake.

Mark drew a long, slow breath, closed his eyes, then sagged down a bit more and let buoyancy carry his weight. The flow of urine was slow due to the black latex shell, but it was constant and plentiful. For several minutes he stood there before he managed to get beyond a tiny trickle. A warmth and pleasure grew in the fox's groin as the first flow of fluid in more than a day made its way from his body. The sensitivity within had not faded nearly as much as outside, and caused him to moan gently. His shaft grew slowly from his sheath, and the warm liquid embraced it beautifully. So distracted by this, when a few vines silently coiled up through the water he failed to notice them.

They ascended from the depths like dozens of silent blue serpents. Each was supported by a two inch thick shaft and had a bulbous, near spherical head. As the first of the group approached it bloomed and revealed its stamen; countless tiny tendrils, no thicker than a toothpick. The mobile anemone immediately went to work cleansing the water of Mark's waste. More and more soon joined in, each from another angle. They drank small amounts of water through the little vines, into the main stem, then down it into the darkness of the lake. Each drew only a tiny amount of liquid, but together they created a gentle current. Soon one of the tiny suckers found the source of all this yellow fluid and made its way toward the boy's urethra, followed hastily by the rest of the diminutive tentacles in the cleaning cluster.

The plant had no intelligence, no thought process, it just sought this source of food. In just another moment the bulb clamped around the tip of the boy's length and drank deeply. The sudden stimulation to his sensitive member immediately got the dazed boy's attention. His gaze bolted down to his crotch to see what was the matter.

"What in the... world?" His paws slipped through the water on either side of the odd appendage and clasped around it, one paw behind the other. He felt the little ripples in the surface as unseen structures within drank down his urine. Quickly the stimulation caused his shaft to harden more and push more from his sheath promptly.

As he grew, his flow began to cut off, and the plant worked ever harder to try to coax more from the boy. Its tendrils sucked and tickled around his length, each one looking for more. Soon one pressed forward right against the fox's slit and began to work its way up into his black-coated cock.

He felt that odd sensation and quickly decided he'd had enough. The fox squeezed around the long tendril and gave it a firm tug. It slipped off his length only a fraction before it re-secured itself in place by dramatically increasing its suction.

A sharp yelp of surprise sprang from Mark's muzzle and his knees buckled under him. The stimulation was simply too much to bear. His toes curled in the sandy bottom, then he sank to his knees; water up to his neck. He resisted for a moment, but soon could not contain a heavy, drawn out moan. By reflex he pulled at it again, desperate to be rid of this thing, but the more he tried, the more it sucked. The bulbous bloom stretched forward and secured itself around the upper third of his now fully hard shaft.

Soon he could not help but to close his eyes, the stimulation too much. Though his bladder was empty, the plant did not go anywhere. In fact, once its food source was cut off, it redoubled its efforts.

High ripples against his face alerted the fox to Marra's movements. She strode to his side just as he opened his eyes. Her head dipped under the water right between his legs and her large, toothy maw slipped right over the bulbous tip of the vine. The wyvern's long, muscular tongue slid forth and wrapped around the plant's head, gave it a squeeze, then pulled it right off with a pop.

It took the todd just long enough to feel a second tendril make its way to his shaft underwater before he bolted upright and backed up several steps, thankful to get away from the sucker. She followed after him a moment later, a bemused look on her face.

He looked to Marra, a little puzzled for a moment. "Err, thank you?" She chirped a little reply, then bumped him in the chest with her nose, toward the shore. The fox followed the hint and walked until he was in water just ankle deep. The vulpine was well soaked, but at least most of the cum had washed from his fur. His black shaft hung out in front of him, knot swollen, and glistened in the sun that now rose fully over the hillside.

She took two large strides; each step sent high waves out in all directions and splashed Mark as she got close. He had already gotten plenty wet, so he just laughed and shook it out. Droplets of water whipped in all directions; the fox's intention to get her back playfully. Just a small spray of water flew toward her, but she chirped merrily and spun away, tail swept low. It splashed into the water and soaked the small mammal from behind. The surprise of it all swept him from his feet and left him sprawled in knee-deep water, all fours. The two exchanged glances for a few moments, before a shared smile crept onto their faces. It just took a little giggle from the fox; they both burst out in laughter. Her guffaws were an odd sort of clicking whooping sound, but merry to the ear.

It took a minute for the pair to calm, but when they did, Marra dipped down and scooped Mark toward the shore with her snout. He yipped in surprise and grasped around her head. As he fell back the large plug dragged against the ground, and the pleasurable shock left him sprawled on his back. The fox panted a few moments in recovery, then but propped himself up on his elbows and looked back at her with a grin on his face. He whipped his paw through the water at her, and sent another little spray at the large predator.

"Heeey, what was that for?" He wasn't sure if he expected an answer. She chirped at him, then slipped her carnivorous maw down between the teen's thighs, under the water and, with a little gasp from the boy, her arm-thick tongue went to work at the remainder of the tough, gelatinous plug; right under his ball-sac. The huge dexterous muscle stripped it away, layer by layer. With each pass the tip of her slightly forked tongue flicked up over his balls, eliciting little gasps from the fox. Soon his fur went along with the dried cum. He did not notice as it simply fell out, that is until the tips of her massive tongue flicked over the sensitive, bare skin right in front of his wide-stretched hole.

He could not contain another sharp gasp at the sensation. He quirked an ear and dipped his paw to the site of the strange feeling and found the skin there incredibly smooth. Though his mind didn't register the fact, it was rather tougher than before, almost like scale. His ears flattened out and a little look of puzzlement filled his face, but as Marra met his eyes and continued to lick between his legs, an odd feeling of calm filled him. "Eh, what's a little fur... it'll grow back."

With a look of curiosity his paw explored further. He felt over the area she had been lapping at. She had worked her tongue under the ring of slid goo just around his wide-stretched tailhole. Just as he discovered this, Marra craned forward and carefully set her jaw right against his skin, and ever so slowly sunk her teeth into the plug, then settled her wing-knuckles into the lake bed on either side of the vulpine's head.

"Now wh..nnng!" His words were ripped from his lips and his eyes screwed shut as she gave it a soft tug. Overnight it had solidified into a tube nearly as wide and long as Marra's ovipostor. He tried to speak, but again he could only moan when she pulled him toward her by the huge, elastic, gelatinous mass set deep inside his gut. Slowly but surely it shifted. The surface inside was rather smooth, and still slick, with thick, musky cum. The warm water grew cloudy quickly as it leaked out with every prostate-rubbing inch of the bulbous plug.

After the initial shock wore off, he opened his eyes, unable to resist looking. She had pulled out only a hand's width, but already his rubber-coated shaft had hardened and pushed quite a ways from his sheath; his knot already swollen, still held inside. The pressure around his sensitive bulb, with the near-constant pulsing and rubbing against his prostate overstimulated the fox in moments.

He groaned and whimpered, then threw his legs out on either side of Marra's head, and soon gained purchase with the sandy bottom. His feet dug in and kept him in place as the wyvern gave a little tug to the stretched, sinewy shaft. A thicker, transparent bulb stretched his already over-stretched hole open just a little more, then popped free, accompanied by another large gush of thick, milky ooze. As it pulled away, it peeled off more fur from between his thighs, and up to the base of his tail.

The murkiness of the water masked the approach of a half dozen ever-hungry plants that dwelt in the lake's depths. They nimbly darted between the fox's thrashing legs, and the bulbous tip exploded in a flurry of activity. The myriad of tiny tendrils emerged from within and, working together, they rapidly sucked away the the milky fluid. In moments they found the surface of the long, semitransparent shaft of goo and went to work at it. They wormed their way in around the plug and sucked right in against Mark's wide hole.

The negative pressure around his stretched pucker helped draw out the mass in his rear just a little quicker. The whole length tapered slowly smaller toward the tip, so as it pulled out more and more of the tiny suckers wormed inside and filled the gap. They feasted on the half-absorbed wyvern cum as rapidly as it came.

It did not occur to the bliss-blind fox that, though this long thing had pulled half out of his body, the eggs within his belly had hardly shifted, as they were safely deposited and kept out of the way, fully fertilized.

Marra changed the angle she pulled from. Rather than straight away, she pulled upward. Mark moaned loudly and pushed at the lake-bed with one foot, while the other drew out of the water and settled on the wyvern's snout. All his toes curled and his body quivered from the huge rush that ripped through his body. The stopper dragged upward, right against his over-sensitive, latex-filled prostate. With a final squelch it pulled a loud yell from the fox and splashed out of the water, where it swung free in the wyvern's maw.

Mark collapsed backward and panted heavily as the plants rushed back to his partly-gaped hole. Two vied for position. All their tendrils suckled over the changed flesh, and many dived into his hole in their tireless search for more to slurp up. He cried out and kicked at the ground for several seconds, before he got his wits about him and pushed himself backward until the plants had no choice but to pull away, lest they leave the water.

He groaned and flipped up onto his knees. The sudden lack of something so large that had been inside him for over half a day left him with a feeling of emptiness. He turned his head toward Marra, who had stepped out of the water onto the large mass of porous lichen that made up the shoreline. In her mouth was the thing that she had just taken so much care to pull out. It had to be at least as long as his arm. She let it drop messily to the ground, then turned to bask in the sun, wings outstretched.

Mark Soon followed suit. He didn't have the energy to stand, but he managed to crawl out of the water. Once ashore, the fox sprawled out on his back and groaned as the black leather tracking collar pressed against the back of his neck. A paw drew up and felt at where the catch should have been but it seemed to have melded over into a smooth loop of leather.

He sighed and just accepted it, then turned his attention back down between his legs. His shaft had been no less than half hard ever since the doctor put on the strange flowing-latex seal over his foxhood, and after his latest ordeal with the sucker plants, it was rock hard; tip rested atop his lumpy, swollen belly. He was afraid to try to pick at it with a claw, since it was so sensitive. He took it gently in a paw and found he could manipulate it without the paralyzing blast of pleasure. He sat up with great effort to look at it more closely.

The sunlight offered him a much better view of the material. It had faded just slightly, and became just slightly transparent. Underneath the coating his shaft pulsed with arousal, and gave it a faint red tint. He had to do a little double take, but it looked as though his length had grown a little bit larger. Next he turned his attention to the nude patch between his legs. He could not lean over his belly too well, so he explored primarily by feel. Now that they were out of the water, he felt the raised texture on his skin. His explored further and his paw slid down toward his hole. A look of surprise shot through his face as they made contact with it much sooner than he expected.

His anus had lost its former shape. Though his belly kept him from being able to look, he felt it was at least as long as his paw was wide. He flexed his rear and managed to squeeze partly shut, but it stayed partly gaped, and watery cum leaked out over the nude base of his tail. With a sort of dread-filled curiosity he probed a digit inside, but he immediately ripped his arm away and flopped out onto his back at the sensation that swept through his body. The small surge= slowly rekindled the strange, but pleasant feeling that had only partly faded from his the messy 'breakfast in bed' served by Smith little more than an hour ago.

He pulled his legs together and ground them back and forth as a little moan issued fourth from his maw. Again he sat up with care and crossed one leg under the other. His paw slid down and gently pushed his swollen, heavy balls off to the side. Contrary to what he thought, it was not his imagination, they had in fact swelled by more than half since his arrival in this bizarre laboratory due to the chemical mix that seeped into his every pore.

With the same care one would use to touch a wound, Mark's paw settled atop the drooling slit. The sensation had already increased, and caused a little shiver to travel up his spine and fluff out his damp fur in the warm sunshine. Slowly he sunk one fingertip, then another into the moist passage. The pleasure that tingled its way through him drew his eyelids down and his muzzle open in an inaudible moan. His curiosity and desire soon got the best of him, and more digits soon made their way into his sensitive crevice. He found that the flesh was elastic, stretched quite easily around his adventurous paw. Quite soon all but his thumb had sunk into his wet cavity awkwardly.

He found that a flap of skin separated his bowel from a second passage into his body. The new hole was situated closer to his belly, and the flesh there felt rather different. It was firmer, more muscular, and far more sensitive. As his index finger grazed just along its surface a sharp gasp sprang from his lips, and he could not help but to delve into it further. The passage soon grew saturated as it produced a musky, unnatural fluid, which only added to the mess than drained from his hole. With every touch the new muscles asserted themselves, and flexed around his paw.

By then, Marra had noticed the fox's explorations of his new anatomy, but the mother's attention was elsewhere. Her keen senses had alerted her to Smith's presence high in the sky. He approached quickly in a long gliding dive. Carried in his talons was a hunk of fresh raw meat more than half Mark's size, intended as a sort of present of appeasement for his larger mate.

He beat his wings just as he neared the ground, and dropped the meal a short distance from Marra before he landed. She looked at him warily, but the meat drew her attention. She was hungry after all. With a little glare she stepped over to the gift, sniffed at it, then tore away a fair sized bite.

Meanwhile, Smith walked over to the distracted fox. His every breath drew deeply through his nose, and he reveled in the lovely scent that hung in the air around the vulpine. As he stepped close, the feral-minded wyvern slipped his head down just beside Mark's chest, and drew a long, slow breath through his nose, basking in the altered musky scent.

So lost in exploring and pleasuring himself, the boy did not notice Smith's presence until the beast was almost on top of him and his shadow passed over the fox's face. His eyes fluttered open and he gazed, glassy-eyed at the large, scaled creature. His muzzle quivered wordlessly, and his messy paw stilled for a moment, buried up to the knuckle inside himself.

A deep rumbling churr grew deep in the wyvern's chest, and vibrated the air around the dazed todd. Smith dipped his head lower and slipped it between Mark's knees, who had little choice but to spread his legs at the insistence of the horny beast. He drew a leg up slightly and pulled his paw from his slick passage with a gentle sigh. A long streamer of fluid connected his fingers to his hole, but it was quickly licked away by the wyvern's long tongue. He splayed his fingers while Smith eagerly lapped between each digit.

As soon as it was mostly clean, he turned his attention to the source of all that wonderful scent. His long, forked tongue darted forward and lapped repeatedly at Mark's sensitive flesh, eliciting a sharp, heady moan from his muzzle. He closed his eyes once again and laid back on the ground so that he could spread his legs more, eager for more of that wonderful, dexterous tongue. It worked deeper with every lashing of his talented tongue, and soon his new passage flexed and quivered around it as more musky fluid oozed from its walls.

Smith only pulled himself away long enough to hook his nose under Mark's knee from the outside. He gave the boy a solid nudge and half-flipped him onto his side. It took his addled mind a moment, but as soon as he got the hint, he rolled onto all fours, arms at his sides, face and chest on the soft ground.

The licking lizard warbled low and darted forward, licking more eagerly than ever as his slit parted, and once again his shaft emerged, inch by glorious inch, his long tongue delving into the deepest untouched spots of his slowly changing body. With no more warning than a sudden lack of licks, the wyvern pounced forward upon his little mate. This time it was not for reproduction, it was entirely for his enjoyment.

His tapered shaft dripped pre as it probed forward against the fox's damp butt. That heavy, strong tail set against the ground as he bacame lost in his rutt. His feral mind demanded he stuff his shaft into the small being below him. For just a moment his cock drooped down between Mark's legs, then spring back up. The tip slapped just behind the mammal's balls, then dragged upward, right into thatstretched, altered passage. The instant Smith felt that wonderful heat around the tip of his member, he lost it.

His hips slammed forward and buried his entire length inside the fox in one savage thrust, causing him to scream out in a mix of pain and ecstasy. He felt the eggs within him shift around as that massive tool slammed into him over and over. Every hump forward sent that rod right into the fox's new ovichamber, and his tip wriggled around inside. jet after jet of pre pumped forth, refilling the vulp with new, hot, musky fluids. His wings came down on either side of his mate and he leaned forward, thrusting all the more rapidly as he grew close. His cavernous maw came down and slipped over Mark's shoulder, engulfing it in a mating bite, his venomous fangs again just piercing the skin, delivering a minute dose.

Again Mark let out a scream of pain, but it was immediately washed away by unbridled lust. He found his paws gripping at the ground as he tried to push back against every thrust. His tail curled tightly around Smith's thigh as that venom coursed through his veins. Combined with the pounding, and the aphrodisiac fluids that accompanied them, the fox was sent into a state of bliss. He lost track of all senses other than pleasure.

Both paws drew inward and grasped at his achingly hard member. He was desperate to cum, maybe even more-so than Smith. He stroked up and down his slick, black-coated shaft with one paw, as the other squeezed and caressed his swollen knot. Every few moments felt like another orgasm to the fox, and his prostate worked overtime, flexing deep inside his gut as it was pounded repeatedly by the massive shaft that filled him so perfectly.

Smith's thrusts slowed suddenly as the walls of Mark's formerly virgin passage milked constantly at his member. He let out a deep growl around the boy's shoulder, then slammed forward hard. The tip of his shaft thrust between a pair of eggs just as he was thrown into his second orgasm of the day. His huge form shivered and his hips quivered forward in a series of tiny humps as he came in thick, heavy jets, replacing all the cum that had leaked from the fox's tail, and seeding his new passage for the first time.

Whimpers and moans of desperation filled the air, all from the little fox who kept pawing at himself frantically, until for just a moment, the barrier that blocked his semen from escape failed. Just a single small jet of cum lept from his twitching shaft and splattered to the floor.

For a moment Smith's nose twitched as that scent met it. All at once he ripped his shaft from within the fox, then sunk his fangs fully into his left shoulder, piercing his skin from either side deeply, and pumping him full of his powerful venom.

Marra sprang into action and threw herself at the crazed male, easily tackling him to the ground with her superior strength. She gave him a strong bite right at the back of the neck and injected her own paralyzing venom, which took effect in moments, leaving the wyvern on the ground, bleeding slightly from his wound, and unable to move more than to breath.

The experience to Mark was a blur. All he felt was a sudden burst of pleasure, then more pain than he's ever experienced. It was too much for his mind to handle. He blacked out just as Marra was scooping him up in her talons to fly him back at desperate speed to get him help.

Well, that's part four! Not as good as three in my opintion, but it's leading somewhere.

I already have plans for what to do in part five, too!

Hopefully it won't take me another six months to a year to do, eh?

Oh, and please comment! I love them, and will reply to all of them!
