Kevin's sleep was deep and restful, mostly out of necessity considering the ordeal that the prior evening had been. A sharp growl roused him momentarily. Kevin briefly beheld Eva up on the wall, jaws yanking at a sticky black mass that was affixed there. Had he been in better condition he might've stopped to gape at the sight. Eva was several feet off the floor, pushing against the wall with all four limbs to yank her prize loose. A yip or a growl occasionally accompanied the jerking of her head in her efforts.

Kevin wrote it off as a strange dream and instantly fell back into a deep sleep. Eva continued prowling for a bit, but likely a stampede of elephants wouldn't have woken her mate for more than a moment or two. Perhaps not the best state to be in when there's a wily balloon vixen with a penchant for late-night mischief around.

Kevin blearily awoke to find Eva lying on her back at his feet, distended jaws mid-way up his thighs. The emptiness inside him nagged incessantly from the depths of his abdomen. How could he be worrying about something like that when Eva was eating him alive? Her throat slurped gently as she took in another few inches. He tried to move, but he was still half asleep. A voice from the dream he was having spoke warmly in his ear.

"Shhhh... just let it happen. You two can be together again. Wouldn't you like that?"

He would. He relaxed and slid down just a bit more into Eva's waiting maw. Ever one to reward cooperation, Eva deftly licked at Kevin's sheath as it slowly came into range. His overworked member was long past the point of responding and elected to remain concealed, but the contact was still electrifying. Eva's gentle licks set Kevin at ease and he drifted off again without further incident.

The one thing Kevin remembered feeling the most was satiation. That empty spot was finally being filled in a big, big way. Thus fortified, he finally broke free of his crippling exhaustion and slowly regained his grip on consciousness. He awoke to find himself greedily gnawing on a latex undershirt. He was standing, somehow, and Eva was having a midnight snack with him along for the ride.

Eva had never before been able to hold him up without his support. The fact that she could do so much without the slightest bit of help was a tad disconcerting. Kevin hoped that he still had control over his body, but resolved to worry about it later. For now he was really enjoying his meal. And what a meal it was. He looked down to see an EEE bag that was missing half-a-dozen latex shirts, and his own plump belly, ostensibly full of near half-a-dozen latex shirts.

The sight of his distended stomach concerned Kevin, but the feeling certainly didn't. That unbearable emptiness that had plagued him as he teetered on the edge of consciousness had been banished by a pleasant, warm satisfaction. He found his jaw muscles eagerly joining in on Eva's effort, making short work of the remaining latex. He greedily gulped the partly dissolved slurry and rubbed the rotund addition to his form.

He couldn't describe how thoroughly he enjoyed that full feeling, amplified by the gentle, driving purr that filled his body. He counted it as the latest in a line of very good mornings. He walked over to the window to gaze out at the shadowed landscape. What he first thought was the dead of night was actually a touch of predawn gloom just barely cresting the horizon. Always darkest before the dawn it seemed...

"Just couldn't get your fill last night eh?" He quipped.

"Oh, don't sell yourself short. I got a feast and a half thanks to you. I wasn't really hungry; I just needed you inside me again. And the thought of swallowing you up..."

It was astounding how quickly Eva shifted gears into murring and sensually rubbing herself. Kevin worked to reign in his sudden panting and the roving of his handpaws. He didn't want the quiet bliss of the moment to be interrupted. Eva seemed to understand, she strained to still herself and pick up her train of thought.

"As for the rest, I thought that I'd help you out replacing everything I squeezed out of you."

"Much as I love to exaggerate..." Kevin had to work through a sickly sweet, chemical tasting burp before he continued. "I doubt that I was drained by quite this much."

"Well, you know... they were really tasty, and you didn't seem the least bit bothered. I got the impression that you were enjoying yourself more than I was."

Kevin would've commended Eva for her perceptiveness if not for the hardon that had been rubbing up against his belly that made his take on the situation rather obvious.

"Seems you've recovered a bit, no?"

"With truly alarming speed," Kevin observed as he considered the needful pressure in his loins, seemingly egged on by his stretched gullet.

"Well then, weren't we in the middle of something?"

There were entirely too many implications associated with that statement for Kevin to be mortified of any particular one. He felt his eyes drift towards the closet. Eva sensed his distress and threw him a bone.

"You had a gift for me, love?"

"Oh, oh! Right. My, how easily I seem to get distracted these days..."

Kevin picked up one of the bottles of bright green fluid that had been the subject of so much tribulation the previous day.

"Sorry if I ruined the surprise, but I think you'll like it."

"Well, you can still present it to me properly. Would you like to?"

"I'd like nothing more." He set the bottle back on the floor.

"All right, I'm in. Just give me a minute to slip into something a little more comfortable."

Kevin laughed at himself for thinking for a second that he knew what was coming. Eva traced her hand down his shaft and gently rubbed below his belly. Her kneading touch slowly rose in strength and breadth, softening Kevin's second skin. He felt the coating slowly part from him in a rim around his crotch with a gentle squelch of fluid latex. Eva kept rubbing at the edges mmmhing gently as she worked. Kevin could feel the dissolved latex being worked into his skin.

What little he could see of his exposed skin was spider-webbed with a growing mass of green. The sensation was so enthralling that he almost felt withdrawal when Eva finally removed her fingers. He didn't even have time to sigh in frustration before her hands made it to his chest to repeat the process. Kevin felt his skin swell just the slightest bit from the extra mass as Eva dissolved her breasts into him. She kept rubbing long after she had disconnected herself, apparently still very much enjoying the motions.

With a noteworthy degree of reluctance, Kevin finally felt her mouth stretch out over his face, exposing his skin to the open air once again. She slid off quite smoothly, already reconstructing herself as she spread out on the floor. Kevin could hardly wait for her mouth to reform before he started filling her up. He couldn't tell when he'd stopped blowing and started kissing and he didn't care. Maybe it was the spirit of the moment or somesuch, but an idea wormed its way into Kevin's head as he looked into her eyes. He saw something in them that sparked his imagination. He helped her to her feet, still hardly an effort, but the difference in her weight was considerable.

"I'd like to give you one present that's still a surprise, come on."

Eva found herself swept away to the bathroom by her hand; unable to express her excitement in the second or two she had been afforded. Kevin stood her in front of the wide mirror over the twin sinks as he flicked on the shaving lights. He couldn't help but smile at the sight of Eva squinting as the bright beams danced across her skin. He had no idea why he found the idea so whimsical, but he resolved not to stray from his purpose.

Kevin, still guided by that errant little romantic impulse, put his arm around her and spoke warmly in her ear.

"Have a look, dear. Look at what you've become for me."

Eva watched the figure in the glass as it gasped sharply, a look of unrestrained wonderment crossing its face. This woman was so far removed from how she remembered herself she nearly thought it was a trick. The self-image she had in her mind was one of a simple toy with a tiny spark of life, body molded by convenience of structure and shaped by air pressure. The woman before her was a vision to behold.

Her hair now easily reached her shoulders. It thinned to a much more realistic taper and was possessed of bouncy, lifelike curls. Far from simple, functional lines, the contours of her limbs followed the trace of artfully toned invisible cords of muscle. Her shoulders had once narrowed to meet her neck, where now they looked firm and imposing. Her legs... Well, they looked like she had attended step aerobics with a group of velociraptors. It broke the flow a bit, but an otherworldly quality of inexplicable grace flowed through their every curve. Her breasts were just as lively as ever, and had expanded to keep pace with the rest of her. Speaking of which...

Her mouth hung open as she saw that her head was level with Kevin's. Past that if you counted ears. She felt foolish at her complete lack of words. Her unresponsive jaw wobbled through a single star-struck phrase.

"I... I'm so... tall..."

Kevin laughed gently as he hugged her tight. Their joy was palpable. Eva felt near tears even as her voice found its way back into her mouth.

"No, no really!" She giggled. "I used to have to worry about getting my nose stuck in your pocket and then reach up to barely nuzzle the collar of your shirt if we hugged like this."

"And that was on your tip-toes."

They shared a mirthful laugh for a few beautiful moments before Eva felt her gaze drawn back to the looking glass. Now that Kevin had pointed it out to her, she couldn't stop noticing how much she had changed. Her tail waved and curled gracefully behind her now that she was facing to the side. It had been such a simple decoration before. Yet now it was such an integral part of her that it pained her to hide it when Kevin wore her. She saw her once stubby, puffy fingers now wrap gracefully around her lover's arm, doing their best to approximate proper hands for his benefit.

Something wonderful occurred to her with startling suddenness as she gripped his arms and felt the tough sinews beneath her fingers. The tone of her muscles, the strength of her shoulders, the solid build of her frame, it had all come from Kevin. He had given her the best of everything he was. She found that her voice had left her again and tried to convey her gratitude with a look as she took in his vibrant green eyes.

She gasped anew and pointed back to the mirror.

"Kevin, look! We switched!"

A quick glance brought Kevin up to speed, and put a tremendous smile on his face. The calm azure blue that had looked back at him from the mirror all his life was now rendered in flawless relief on the mirror's surface, in the eyes of his lover. His reflection had, in its place, the radiant emerald green that he had come to know and love only recently.

"That's not it either. You... look what you've become for me."

Kevin was taken aback by the reversal, but considered his own reflection regardless. His attention only briefly grazed the glaringly obvious changes. There were patches of green around his new equipment that seemed to have spread a little more every time he looked at them. His sac had grown notably. Within it he felt the gentle stirrings of his system working overtime to restore his inventory of seed. He took in his perpetually perky nipples and their surrounding rim of green. The creeping ridge of latex-infused skin was now large enough that the two circles met in the middle of his chest. The new paunch in his middle that worked strangely well on his frame was the last of the various things to receive a cursory glance as Kevin near-instantly saw Eva's point.

The artist that had crafted Eva out of the very ideal of beauty had apparently been asked for a second opinion on Kevin's form. Now entirely stripped of hair, his skin shone in the glaring lights with an ethereal perfection. Smooth, graceful shadows lined the contours of his body. The air of transcendent grace that surrounded Eva had spread to him, smoothing over his human faults and making him the perfect match for his perfect fantasy woman.

Neither could really say any more, they exchanged expression of joy with a kiss before finally tearing themselves away from the magnificent gifts that they had given each other. They had put it out of their minds for a moment there, but they had been staring at each other's naked bodies for long enough that the light of the sun had broken over the ridge in the east. There was only one place to go from here.

Kevin practically ran after his lover as she led the way back to his room. Their urgency wouldn't wait for trivialities like turning around. Kevin hugged her close and kicked the door shut in a single motion, reveling in the enhanced sensitivity on his chest as he pressed her back tightly against himself. Eva curled a flexible arm around his neck to pull his lips to hers. Kevin was kicking himself for not noticing how much Eva had developed earlier. Here she was, altering her body, changing who and what she was to please him, and he could only quibble about details and worry about consequences.

Strangely, his remorse added to his arousal. He had to make this up to her. She had done so much for him and only asked for one thing in return. His hands quickly slid to her hips as he maneuvered them past his stuffed belly. He lowered her onto him, sliding his shaft smoothly up her passage. Eva moaned in surprise, but couldn't bring herself to break the kiss. This was so unlike him, to just take her without preamble. Yet she realized that this was exactly what she needed as surging heat coursed through her from her loins. She was about as hot and bothered as she could get just from looking at him. Suddenly it almost felt like he wasn't going fast enough.

Eva gripped his arms, working up a rhythm to match his driving thrusts. Their lips parted at long last as they both gasped for air, the rapid building of their peaks startling them both. Eva felt the spike of pressure from his knot at the end of each thrust. She knew that he was trying to knot her already, and that the consequences of such would be rather unfortunate for him. There would be nothing left of him by tomorrow morning if they tried that again. And she'd never get her gift if she let that happen. No, there was much more fun to be had if she headed him off right now.

She heaved her hips and gripped his cock as best she could. The strong, rippling touch had an immediate effect. Kevin moaned aloud and pressed his knot against her entrance once more as he came explosively into her. Kevin could feel the devious little machinations that Eva had placed within him working their magic. His innards heaved in earnest, seeming positively gleeful at the prospects of all the new raw material that he had eaten for breakfast. Just when he was thinking that the flood of cum would never stop he shuddered beneath her as his knees weakened. Eva used the opportunity to slide deftly off him and turn to face her stymied lover.

A little fog of climax still hung over his face, but his member told a different story. The bright, glistening length still throbbed and begged for attention, clearly nowhere near satisfied. Eva smiled as she sized him up. She traced a few deft fingers along his jaw line as she spoke.

"Now then, you had a gift for me?"

Kevin blinked, taking entirely too long for his mind to return to the twice-forgotten bottles off to the right. He bent down to pick one up. He wasn't much for ceremony at the moment. The instinct to pounce on his mate that instant was still foremost in his mind, but he still managed a few words and a grandiose smile. He would hold off, for her. He held up the bottle and briefly appraised it like a fine wine.

"Oh what a long, strange trip it's been...Well hon, happy one week anniversary."

He extended a bottle to her and she graciously lifted it from his hands.

"Oh how thoughtful! You always know just what to get."

Her claws had some momentary difficulty with the cap, but soon there was a satisfying click as the squeeze bottle flipped open.

"Let's have a taste, shall we?"

Kevin's fascination momentarily overtook his lust while he watched the strange fluid trickle down her throat as she took a sip from the bottle. The trickling stream merged into her skin rapidly, seeming to ripple as it spread.

"Mmmm... Not bad. It's kind of-"

Eva's mouth hung open as she appeared momentarily overwhelmed. She found her fingers fumbling at the cap, unscrewing it completely. Kevin took a worried glance at the lengthy, fine print warnings on the side of the bottle. They featured a number of threatening symbols and bold red words. He knew that much trouble could be stumbled into by ignoring such things, but couldn't even get a word out before Eva was guzzling the bottle with a bestial grunt. The fluid spread even faster, the waves and ripples in her skin elongating and broadening with it.

"Eva, are you sure this is a good- oh, okay then..."

Kevin's warning fell flat as he watched the enraptured fox wrap her jaws around the bottle and force the whole thing down. A stunningly fast gulp brought it down into her abdomen. Kevin watched as the plastic deformed, slowly ebbing away and releasing the contents within.

Drool and latex sludge trailed out of Eva's mouth as she rubbed her belly, clearly enjoying herself very much. She opened her mouth as if to speak, but her jaw simply fell open and her tongue lolled out to the side, accompanied by still more latex spittle. She made a guttural noise that was half an attempt at words and half a pleasured moan as a gusher of fluid broke forth into her gut.

The surging fluid became ever more aggressive. Eva's eyes widened and her noises took on a more urgent tone. Tears started to leak down her paralyzed face. Kevin suddenly saw it. She wasn't drooling, or crying. She was liquefying. Her eyes narrowed to pinpricks in terror before they deformed and began to streak downwards. She reached out a flagging, drippy arm to him.

Kevin was mortified. The sight itself was the stuff of nightmares, but Eva was also in big trouble. He did the only thing he could, tried to comfort his lover as her legs began to dissolve beneath her. He grasped her melting form and pleaded to her.

"Hang on Eva! It's going to be okay. I won't let you fall to pieces."

What expression could be made out on her face was unchanged; she was still terrified of what was happening to her.

"I've always been the solid one, love. You need that now. You need me now. Cling to me to hold yourself up, like you always did."

At another time, Kevin would've found the creeping sensation across his skin very disconcerting, but this time it meant that Eva had taken him at his word. He saw a glimmer of hope in her eyes before they vanished into the tide of green sludge that was now clinging to him and spreading across his skin. He felt any sense of substance leave his hands and looked down to find them empty, covered in a green film. His feet were immersed in a pool of what remained of Eva.

He looked down at the pool in dismay only to find that it was working in earnest to make its way up his legs. The sludge gathered up, forming small peaks around his ankles. Thin rivulets trickled up his legs. They looked almost like they were dripping from gravity, but for the fact that they were dripping in the wrong direction of course. The tiny trickles gained in strength and thickness as their meandering paths established themselves. Kevin was transfixed by the shifting mass even with how concerned he was for Eva's fate. He prayed for a sign that she was still alive in that slurry, that she would be okay. It was mere seconds before he got it.

A droplet from one of the more industrious streams of fluid touched the patch of green skin at his crotch. He felt a burst of pleasure as it dissolved into his skin. Only Eva could make him feel like that. She was still alive, and in good enough shape to concern herself with making him feel better. Kevin's joy and relief at the signal seemed to invigorate the activity of the blob at his feet. Streams of liquid lanced up his chest, soon spreading up to wreathe his neck. The stream that touched his crotch gained in strength, merging more fluid into his skin by the second. Two more found the altered flesh at his nipples, with similar results.

The pleasure soon overcame him and he dropped to his knees, squishing gently into the lively little puddle. He couldn't help but throw his hands down for support as the sludge grasped at him with impunity. It lanced up his arms, consuming him in no time now that the obstacle of his height was removed. Kevin finally got around to feeling some apprehension as the fluid overcame his head and started blocking his eyes and nose. She had been complacent about his need for oxygen before, did she still remember? His tribulations led him to clench his jaw against the streamer attempting to intrude on his mouth.

Eva seemed not in a mood to be denied though. The stream attached to Kevin's crotch took a break from further augmenting his flesh to trickle down to his asshole. Kevin's jaw obediently swung open in a heady moan as the fluid spurted up inside him. No sooner had the fluid snuck down his throat did Eva's own lustful moans make themselves known from within. Each of the pair had only seconds to try to figure out what was happening before a new, tantalizing sensation gripped them.

The pool on the carpet had vanished; all of Eva's mass had been taken up in the serpentine pattern that covered Kevin's body. Ripples of movement cascaded across his skin. The advancing droplets began to halt in their places, the little streams now forming stripes and bands across his skin. She was solidifying again! Kevin briefly thought that the drama was over, but he knew better. It always seemed like the chaos was just beginning with her.

"I... I'm sorry," Eva breathed as she finally gathered her wits again.

"For what?" Kevin asked. "For trying something new? For being overexcited? For getting a bit frisky in the process? I count those under 'being yourself.'"

"For worrying you so. I didn't mean to-"

"Eva, are you okay now?"

"I... Well I feel a little weird, but I think it's a good weird. Yeah, I'll be okay."

"That's all that matters."

Kevin shakily got to his feet and looked himself over. He had full vixen gloves and boots, claws and all, from where his hands and feet had been completely immersed. The rest of him was covered in that streaky webbing of liquid fox that had frozen in place in whatever haphazard condition it was in at the time. His altered flesh seemed to serve as nodes for this unusual network, the streams connecting there at many points.

Eva seemed, for a moment, to be trying to think of a good way to say something. In the end, she just blurted out:

"Wanna do it again?"

"I- it... what?"

"Well, I mean it was kinda fun and we have that whole other bottle..."

"You never skip a beat, do you? You just almost died and you want to have another go at it!"

"I didn't almost die! Probably... I'm not sure exactly how dying works for me..."

"All right, one step at a time here. What exactly put that thought into your head?"

"I... I miss my tail."

"Okay... Yeah, now I'm lost. Would you mind connecting those thoughts together for me?"

"I can't change shape like I used to. I've been trying to grow it back but it just won't happen. Either the paint changed me somehow or I used up too much of my body on you and there's nothing left."

"Or some combination thereof..." Kevin reflected on how easy and natural the transition between their voices had become of late as he considered his mate's desires. He knew that this was important to her, but was it worth the risk? "What makes you think-"

"Well, you see there's a whole other quart there. Plenty of latex to work with if that's the problem, and while I can't change my shape much now, I could do anything when I was liquid. It was like I could feel the potential there. I was just too freaked out and confused to use it properly."

"Well I'm glad one of us thought this all out. All for want of a tail..."

"Well, don't you want a tail?"

Kevin felt control of his vocal cords fall back to him, but he couldn't come up with an answer in time to get it to the air. It seemed to fit. A few vulpine features were showing through the droplets and rivulets that textured the latex that streaked his body. It wasn't necessary to hide her tail as part of a disguise now. No one would be seeing them anytime soon. It wasn't right to deny her this anymore. It would be like someone denying him a hand or a foot because having two of each would be inconvenient. She was born with a tail. It was her right to have it. He found himself kneeling before the bottle and wasn't sure if it was against his will or not. As he looked at it, he felt his lip quiver and his eyes widen affectionately, tears welling up at their edges.

"Are you trying to give me the puppy eyes using MY eyes?"

"Is... is it working?"

Kevin sighed deeply. "All right, you've got me. I'd like a tail too. In fact I'd love one." He felt a squeal of delight just inches from bursting out of him, but he kept hold of his throat to make his point. "But I'd like to have some idea of what's going on here. Give me a chance to read all these warnings."

Kevin peered at the tiny print, finding his vision strangely crisp in the morning light. The words he read were not particularly encouraging. Though a few were rather amusing in light of recent events. He read some of the richer ones aloud.

"'Do not ingest.' Heh... Right... 'Avoid exposure to direct sunlight'" Kevin considered the bright sunshine streaming in from the nearby window and shrugged.

"'Allow ten to fifteen minutes to set completely.' That took fifteen minutes?" Kevin could've sworn that it was far less. "I wonder what else happened in that temporal vortex... Anyway, 'Avoid covering nose and mouth, product may obstruct breathing.' That's a big point of order that you should take away from this, Eva."

"I said I was sorry!"

"Humph, so long as you learned something. Let's see here: 'Avoid contact with eyes'"

"Yeah I know, I know."

"'Do not wear for periods exceeding four hours.'" They both had a quick laugh about that one. "'May stain carpet or upholstery,' Looks fine to me actually."

The carpet showed no sign of being previously doused in balloon vixen. Quite impressive considering the moat that she had formed only moments ago. And so the reading continued. Quite dry, as one would expect. A number of oddly specific warnings hinted at previous consumer follies. Some of which were sure to be priceless. It wasn't what you'd call exciting, but it gave them a chance to reminisce about their relationship thus far, and the unusual circumstances therein.

"'...Avoid encasement of entire body.' My God Eva, all we need are a few petroleum based solvents and we'd have the complete list of stuff we're not supposed to do checked off."

"We'd have to get near a few open flames too."

"As I recall you had that one covered making breakfast the other day."

As Kevin skimmed the more technical portion of the label he noticed a green droplet lazily working its way down the side of the bottle.

"What are you up to?" He asked, surprised to find that one of his claws had pierced the bottle.

"Err... taking initiative? I guess..."

More and more dripped over his hand and down the bottle, quickly starting to eat through the plastic. Kevin tried to release his grip, but it was stuck firmly to his hand. Bolts of sensation leapt up his arm as he took a wary step backward. He couldn't even manage a word as the surge of rubbery goo overwhelmed him. He fell back onto the bed, bursting the weakened bottle across his chest. His body was on fire as the slime came alive on contact with him. It flowed across him with drive and purpose, enlivening that which had already adhered to him. He was paralyzed by the consuming sensation of the ripples wafting over his entire body. His skin was completely covered before he even knew it.

The sludge shifted again, concentrating its motion inward between his legs. Kevin could've imagined any number of devious intentions for its presence there, but found the goo merely massing at the base of his spine. He remembered Eva's one desire and was elated to see that she was getting her wish. A thin ring formed and extended outward, forming a supple length as it gathered mass.

Kevin was amazed to see the hollow tail supporting itself as it formed. The tip was still open as more and more fluid raced to the end to build it up. The tail was coming into being already filled with air. The strength of Eva's skin was astounding, and it appeared that she had mastered the nuances of the body paint as she said she would. The coating on Kevin's body was nearly flawless, and the completed portions of the tail were drying to a mirror shine.

Kevin shared in Eva's joy as the tail's tapered tip finally sealed off. His second skin still felt restless though, twitching and pulling at him. His new tail jerked irritably too.

"What's wrong love? Isn't this what you wanted?"

"Oh, it is. Better than I dared to hope, but it's still missing something. It's so hollow, so empty..."

"Forgive my bluntness, but hasn't italways been that way?"

"I know, but I love being filled by you so much it just... it needs more..."

Kevin felt his body roil in a new and powerful way. His member shifted in his sheath as the motions stirred it to life.

"Eva what-"

"Don't worry, I'm working on it."

Those words were perhaps the least comforting thing that Kevin had ever heard, but the gentle stroking of his member set him at ease. All this goo business had him on edge whether he realized it or not, and it was an indescribable joy to have his needs met. More and more of him joined in on the effort as he quickly approached his peak. His legs heaved and his back arched obligingly in time with the increasing pace of Eva's stroking. He felt his lips pull into a mirthful grin.

"My, someone's quite eager today."

"Mmmph, can you blame me?"

Further words were lost to him as she gripped his knot. He was astonished by what power she wielded over him with her newfound skill. It was as if his entire body was in a vise, every last nerve begging for release. Such elation followed that liberation that Kevin still couldn't move or speak for several minutes. He just lay there basking in the afterglow, watching as his copious load was whisked away by his second skin.

He felt an odd trickle that snapped him out of his blissful stupor. He noticed a pool forming in his new tail as it lazily curled one way or the other across the bed. He felt his body rise from the bed and lean forward again, recapturing his attention.

"Oh, you seem to be having such fun. Mind if I join you?"

As always, Eva's signals were about as subtle as a brick in a pillowcase to the head. As she gripped his shaft between a few, teasing fingers, Kevin brought his free hand down beneath his sac. He couldn't say he was surprised to find a pair of netherlips there, but he certainly was taken aback by how sensitive they were. What was once a dull echo now felt more and more direct, as if the pleasure were lancing right through his own skin. Not that surprise slowed him down any. Quite the opposite really.

Eva's stroking became more erratic as Kevin's forceful fingering pushed her to the edge. Her eyes stretched wide as if in sudden realization as his probing touch finally split her netherlips apart. The feeling gave Kevin pause too. The split of Eva's passage led right to Kevin's skin, now slick from her juices and maddeningly sensitive. Their flesh looked identical. It wasn't until he felt it that he noticed the difference between the two. Kevin curled his fingers just a bit and was rewarded with an impressive gout of cum from Eva's femsex. With the barrier broken, it flowed right inside him. A fair bit tricked down to join the pool in his tail, but he felt just as much being absorbed into his skin. It penetrated his flesh deeply, softening it and heightening the sensation even more.

Eva's sudden inspiration took hold and she started thrusting those fingers with even more enthusiastic fervor than Kevin had. He couldn't figure out why she was gripping his knot already, he wasn't even close to his-

A surge of heat drowned out his thoughts. Whatever Eva was up to, it was getting the job done. His knot throbbed in her handpaw, and an urgent pressure seemed to be building up beneath the lips of her slit as well. It welled up from deep within him, it was unfamiliar, but he knew that it was begging to be released. Just as he was about to plead with Eva to go faster, Kevin's peak was upon him. He almost didn't notice the incredible force she was putting into the thrusts of her fingers though the ecstasy of climax, but it became hard to miss as two of her claws suddenly dug into his flesh.

Kevin felt it happen and cried out in what should've been pain, but quickly trailed off into a pleasured murmur. More green goo drained from within him around Eva's claws, relieving the nagging pressure in his loins and adding to the growing pool in his tail.

"Ready for this?" She asked seductively, flexing her fingers in anticipation.

Apparently Kevin couldn't come up with an answer, or a frantic question, fast enough for her, seeing as her arm tensed without another word. Her claws dug deep with a satisfying squelch, the sensation causing another stream of cum to spurt from Kevin's throbbing erection. The feeling in his flesh vanished into an ethereal bliss around Eva's advancing digits. Kevin panted in panic and delirious pleasure as Eva at last withdrew her fingers. It was all so surreal. Kevin's dissolving flesh streamed out into his rapidly filling tail and all the while he had barely stopped cumming for a moment. His bloated stomach churned, working hard to make sure that his supply of latex seed never ran dry.

Just when it seemed that he might get a moment's peace his hands leapt to his chest. They dripped with sticky fluid from their previous endeavors and quickly set to work kneading and caressing his sensitive skin. As the fluid penetrated into him, it seemed to carry with it instructions that his body jumped at the chance to obey. Tendrils and tubes and all manner of tiny, intricate structures snaked through the swelling layers of flesh just beneath his skin. His new additions were invigorated by Eva's thorough massaging and soon began to fill with still more liquid latex. The pressure building in his chest mirrored the rise of another glorious climax from deep in his loins. The release was exquisite as Eva squeezed his nipples, allowing his breasts to contribute their flow to the stream that was filling his tail.

His head slumped to the side and his body fell limp as the pleasure threatened to overwhelm him entirely. His new breasts shrunk to his chest as they drained and his cock continued pumping in earnest, the contractions still driving more fluid out of the rend in between his legs. His entire being was consumed with the effort of constructing his tail. Then, just as if someone had shut a valve, the stream of bliss was stopped. As he recovered his senses, Kevin leaned forward and pulled up his sac to get the lay of the land. There, being neatly sealed into his skin, were the lips of his new vagina. He looked up to track down the source of a gentle sloshing sound and saw his sinuous tail, now dragged down by the weight of a tremendous amount of latex cum, but still swaying and curving gently.

He tried to see if he could move it, concentrating on where he thought the muscles should be. One spot in particular elicited a twitch, and a slightly larger wiggle when he tried again. He fully admitted to being very excited about this. He concentrated on trying to get the tail to move as he wished, his focus preventing him from noticing Eva's faint pleasured squeaks and the pressure building in his own loins. By the time he figured out just which new set of muscles he had actually been contracting, he was much too far gone to stop.

The glorious new open space where his womb had taken root was alight with pleasure as another orgasm tore through his body. In comparison the amount of cum was quite conservative, but still gave way to pleasant squeaking and squelching as the thick film was whisked away by his skin. Kevin's hands reluctantly stilled as he shuddered and relaxed at last.

His wrists came to rest on his belly, now quite flat and smooth, having unburdened itself in such a spectacular fashion. He found that he missed the bit of paunch around his middle. The feeling of filling up inside and stretching his skin like that was so... Actually he didn't need a word to describe it, he could feel it already. His breasts were working to restore their stores in the brief lull, slowly engorging themselves with another gout of goo. Kevin let slip a needy moan as he prodded one experimentally. His nipple leaked out a small stream at the contact.

"Oh... Oh we do have a problem." Eva managed to squeak.

"What's that? You got your big, heavy tail. I got to have quite a bit of fun. I don't see the problem."

"Well, I figured out how to get you to make latex cum like I do."

"Yeah, a while ago if I remember correctly."

"Right. I'm not sure how it works, but I tweaked your innards a little bit to turn your equipment into... kind of a latex dynamo of sorts."

"That's certainly the word for it..."

"Yeah, it is..." Eva seemed to be getting more hesitant as her explanation continued. "And I needed to get a lot more out of you. You know, for the tail..."

"Go on..."

"So I made a few more. The thing is, they're kind of synchronizing with each other and working together."

"So far it seems that teamwork is a good thing."

"Oh absolutely, in the short term anyway. I filled out my tail much faster than expected..." Eva reigned in a sudden bout of panting as she gathered her wits. "It's just... oof... You see I know how to make them... and mmmph... and I know how to g-get them going... but..."

Kevin could barely ignore the mounting pleasure that harried Eva's speech. He was beginning to lose it as well. A creeping realization snaked its way into his addled mind.

"Eva! Are you- ugh... saying that you didn't... p-put in an off switch?"

"Well, yes. Yes! Oh YES!"

The full realization came in a tumultuous rush of pleasure as Eva's devious little machinations stepped up their work again. Eva's shuddering hands could only roughly squeeze the breasts that they conveniently happened to be gripping at the time, releasing another spray of liquid latex and a wave of blissful joy. The fluid was streaming down his skin, inside and out, so much so that he failed to absorb it all. He could feel the excess pooling at the small of his back as the two of them panted and recovered again. The immersion set a deep tingle through his lower back that washed out all sensation from the area, but honestly, a bit of numbness was one of the least disturbing prospects that Kevin faced. He forced himself to speak through the delirious haze that followed climax.

"Okay, so... what exactly happens now?" Kevin was obliged to ask.

"I have no idea. I'm not sure I can even move without- ooh!"

Eva's hand brushed across one of her depleted breasts, the motion sent an arc of sensation down the side of her chest.

"You could've chosen a slightly more innocuous test movement."

"Oh, you mean like the pelvic thrusts that you're doing?"

Kevin looked down to see that his back was indeed slowly arching and relaxing. At the peak of one arch, he felt a sharp jerk and a pop that was muffled by a coating of latex. His self-control difficulties forgotten for the moment, he hopped up and stumbled to his feet to get a better look at what was happening. His neck bent easily around in a way that it probably couldn't before as he tried to get a better look at the new tag-along that waved around behind him.

"Oh, what do you think that is at the base?" Eva asked cheerily.

"That would be my spine, Eva. More specifically the aptly named 'tailbone' portion. It seems to have had a falling out with my hip bones recently and has gone off to pursue its own interests."

Kevin found his threshold for disbelief raised several notches as he traced the short length of bones through the hazy latex sheen of his tail. He shuddered and averted his eyes after one too many glances at the morbid little protrusion.

"If the sight of the bones bothers you, I could over them up." Eva suggested.

Kevin didn't even have time to voice his agreement before he felt a shift in his latex coating. The base of his tail became completely opaque as the swirling currents reached it. Kevin was impressed with her thoughtfulness.

"Well thanks hon, that's really-"

He was stopped by an odd twitch in his leg. It came again a few seconds later, a bit more pronounced that time. In fact, the tremors seemed to be spreading.

"Eva, what are you-"

A shiver shot up his spine that made him stand bolt upright.

"Wow, there's a lot going on in this little thing." Eva observed, seeming to be intensely focused on something. Kevin put it all together during another volley of sharp tingles.

"Eva, I need you to listen to me- Augh! Don't mess with my nerves! I need those!"

He had been a bit less articulate than he had intended to, but the shooting bolts of electricity down his legs were making him ever-more nervous.

"Sorry, sorry, it's just- Oh, well would you look at this one..."

Kevin suddenly collapsed, mercifully onto the bed, as it suddenly felt like his entire body was being aggressively tickled with a feather duster. He was nearly crying with laughter by the time the sensation subsided. Eva recovered her breath first and apparently decided she'd like another stab at spinal cord roulette.

"Wow, there's a lot of them right here..."

A heavy lurch marked the sudden contraction of Kevin's new inner passage. Pleasure and sudden lust sparked between them. It was more intense than anything Kevin had ever felt, not that unreasonable an assessment considering that his nervous system was being hot-wired at the time. Eva's wide-eyed wonderment and unrestrained excitement was palpable as she returned aggressively to the business of tracking down just which nerve would make that happen again. Kevin found himself lacking the will to stop her. He justified it as his will being overridden, but likely it was just that he enjoyed it as much as she did.

"I think this is it..."

A gout of seed spurted across Kevin's chest as his member obediently pulsed and heaved at the signal. Far from blissed-out the way Kevin was, Eva dutifully returned to her research.

"Hmmm... I wonder if I-"

Kevin was nearly blinded by the surge of ecstasy that came next. Every phantom sensation that had been but a pleasant echo now was an overwhelming torrent of pleasure. His cock and his slit both absolutely crawled with tingling excitement. It was like he was feeling both of them for the first time. The feminine squeals he found himself making let him know that Eva likely felt the same.

His male and female contractions ricocheted off each other. One giving the other strength and lending even more urgency to their arousal. The twin climaxes spiraled out of control in moments. There was much more twitching and shuddering than normal as they finally got a hold of themselves again. An unusual creeping sensation in his lower back likely meant that Eva had not yet abandoned her efforts to explore the little bit of him that she had gotten hold of. His back arched again as the sensation continued to rise up his spine.

"All right Eva. I know that was what you were looking for. You can stop now."

The long pause without a reply from her was disconcerting.

"Well..." She squeaked. "The thing is-"

"It's one of those things you can start, but you can't stop."

Kevin felt an innocent smile come to his lips. The puppeteered expression letting him know that he was correct.

"My God Eva, if you had any foresight at all-" He felt her cringe at his words, the feedback made his frustration evaporate. "... then my life wouldn't be anywhere near this exciting."

The happiness that he felt from her almost made him forget about the cracking in his spine as his back arched again. His member pulsed needily as he settled back onto the bed, his libido returning to him almost with physical force. He felt another pop as his hips thrust up and his shoulders rose off the bed. What was she up to? His throbbing member loomed before him, so much larger... no wait, so much closer than he remembered it. Disbelief had him transfixed as his back continued to curl forward, his much more malleable spine inching him ever closer... and closer.

His own hot breath danced across the surface of his dripping length. He strained against his own joints and tendons to reach his prize. His arms tensed to push his hips up just a little bit more... At long last, at the very edge of his range, his mouth closed around the head of his cock. He could barely lick or suck it at all, but the very idea of what he was doing had him spurting thick ropes of seed across his tongue in moments. He didn't even think to swallow, the thick fluid just kind of dissolved away without a second thought. Kevin didn't worry about it, he only hungered for more.

His mouth felt so smooth and perfect now, the touch of his deft green tongue complimented his altered member perfectly. His eyes widened as he felt the latex soaking into the roots of his teeth, to what end he couldn't fathom. Soon his concern evaporated as eyelids began to droop again and he fell back into the blissful trance of autofellatio. Strange sensations passed him by as he focused only on his pleasure. His drool tingled as it dripped down his chin, the sensation soon spreading to encompass his whole head. A few more licks and a few more spurts of cum and it was forgotten.

The only thing that got his attention again was a spike in pleasure that he found had been caused by his mouth sliding down the length of his shaft. He couldn't make any sense of it, he knew that he couldn't reach any further, and yet his length lit up as his mouth slowly encompassed it little by little. His eyes burst open at a popping sound. They beheld a large green obstruction in the middle of his field of view. His cock was being slowly wrapped within his burgeoning new muzzle.

He couldn't even begin to enumerate all the ways that this made him uncontrollably ecstatic. Most viscerally because he would soon be able to take in his entire length, but also because he got to be more like his lover. He got to change himself for her. He begged for the change to continue, his amorous thoughts spurring the growth of his muzzle onward. His skull had softened under the influence of his seed and it stretched and reshaped to suit his new visage. The latex cinched up around his head, extruding his face outwards. He was forced to squeeze his eyes shut again as they made way for the extension of his bone structure. His muzzle pressed onwards until he felt his wet canine nose press up against his knot.

It was then that he became aware of an unusual complication. His mouth hadn't extended along the sides of his muzzle as he would've expected it to. It had remained a small opening at the tip, one apparently insufficient to take in his thick knot. He whined gently in frustration as he tried to wrench his jaws open. Even as he was stymied in the effort, he got the impression that help was on the way. Without prompt, his legs gathered themselves up underneath him, tilting his hips into his muzzle with greater force. Yes, that was the idea. Just a little more might do it, just a little nudge...

He got much more than a nudge as his hand came up and dug a few fingers into his slit. The explosive contractions that this unleashed finally drove his jaws apart and forced his knot between them. His mouth sealed shut around it, containing the voluminous flood of cum that was triggered by the grasp of his maw around his pulsing knot. The Zen-like lack of swallowing was but a distant memory as jet after jet filled his throat. He was glad for the fingers under Eva's purview in his slit; he doubted that he could muster the focus to tend to it himself. All his erogenous zones seemed to have the habit of responding together, speaking of which...

Each hefty gulp of seed brought a little surge to his chest. The small orbs there were filling once again, but not with liquid it seemed. No they were filling up with... him. His flesh roiled as it shifted to fill the burgeoning breasts. The sensation of tendons snapping and muscles rearranging all transmuted to boundless pleasure. Kevin could do nothing about any of it. Not only was he stuck knotted in his own muzzle, but he was practically paralyzed by the onslaught of sensation.

He could only let his attention flit back and forth from one pleasure to another. The endless rush of cum from his shaft, the ever more aggressive fingering of his slit, the engorging mounds that were now rubbing up against his cheeks, it all screamed pleasure and satisfaction to his poor, overworked mind. Even a gentle moan that worked its way up from his throat couldn't go unchallenged by the miasma of bliss. The vibrations of his voice shot down his shaft and tickled his breasts, starting a fresh round of cumming and undulating in the unbreakable grip of ecstasy.

His strength started fading at last. The cum started to build up in his mouth as he literally couldn't swallow it all. The green fluid began dissolving through his cheeks, finally breaking his lockjaw. A few times, just because he finally could, he clenched his jaw around his knot. He was, of course, rewarded with more cum than he'd ever know what to do with. His exhausted jaw finally allowed his knot to escape, his whole-body orgasm finally coming to a close. His tongue hung lazily out of his muzzle, swaying in the rhythm of his panting. He giggled a bit and flicked his pointed ears as the pillow tickled at them. An amusing thought crossed his mind as he drifted off. He'd do it all again right then and there... if he had the strength left to lift a finger.
