Sequel to the first DRM story, this time with Tomoya doing some stress testing on the altered Renamon.


Renamon sighed as she stood in the shower, just letting the warm water pour over her body. She ached, but not in a bad way. There was some part of her that said she should be ashamed, that she should be appalled at what she'd done and what happened to her. It was a distant, tiny voice though. One laying behind countless layers of new code that had been installed in her. She knew, if only vaguely, what she was here for.

A group had found a way to tap into the digital realm that she lived in and they had decided to run some tests to see if digimon could be marketed. Whatever that meant.

What she did know was that they had been mucking about in her code somehow. Altering her with strange little bits and bobs, giving her knowledge she didn't possess mere moments before. Like the breasts that she was currently trying to clean off or the ability to give 'killer head' when she got going. While they weren't the only parts of her that needed cleaning, the plush fur there was matted with saliva and semen. Seems that tiger that had come into her room and told her all this had enjoyed her body a great deal. Having sex with her over and over, even splitting himself into copies somehow so he could fuck her in a wider range of positions. Only leaving when she was about ready ready to pass out from the exertion of it all.

And that's what brought her to this shower. After a few hours of blissful sleep, she woke up feeling rather stiff and crusty. A dim light guiding her into what she knew was a bathroom. The warm shower feeling like pure heaven as she cleaned herself up. It did weigh her down, but it was worth it for how that flowery scented soap left her feeling.

Though the water did leave her feeling rather heavy. She twisted the water off and had started to press it from her pelt when several warm jets of air blasted her. The digital vixen yelped in surprise and half-skipped before stopping when she realized what it was. Letting out an embarrassed huff, glad that no one was watching, she began to scrub fingers through her pelt. Pushing out as much water as she could before fluffing it up as the air blasted her.

Minutes later, she was brushing her pelt down with fingers, combating the frizz somewhat as she moved into the bedroom. A tray waited for her with some food on it. It was only as the scent hit her nose that she realized how hungry she was. Gladly descending on the meal with vigor and a waving tail.

A sigh slipped from the vixen as she leaned back in the chair. Meal devoured, freshly showered, and having had a good night's sleep. She was feeling much better.

"Glad to see you're up," Tomoya was standing over her as she leaned back, the tiger grinning down at her. "Hope you're ready for stage two of testing. I believe it's stress tests today. So why don't we go ahead and get started?"

Shoving the back of the chair, he rocked the vixen back violently. She yelped, arms pinwheeling as she tried to catch herself. The chair only lay back so far, but it was sudden enough that she was certain she was going to fall over. He took advantage of her surprise, shoving his already stiff cock into her open maw. The vixen gulping around the girth as it drove deep. Hands finding purchase on his hips as the tiger leaned over her with a pleased growl. "Off to a good start," he huffed.

Her eyes went wide, then heat flushed through her as the cock pounded right down her gullet. Throat stretching around his member as the tiger hammered his groin against her nose. Legs kicking out as the male held onto the chair, not letting her pull away yet.

Not that the vixen wanted to, that bit of submission code running now, overwriting that surprise and prompting her to wrap her arms around him with a hungry slurp. Tongue curling against his cock as that length pounded deep into her. Eyes narrowed as his balls bounced off her muzzle, drool leaking from the corners of her mouth as she savored the taste of that cock. Clinging to his hips as if that was the only thing that mattered. Her body longing for his touch, craving him more than she even craved air.

Trapped as she was, she was only dimly aware of one of the tiger's clones moving in. Legs kicking as one was grabbed and she was wheeled away from the table. Thighs spreading the instant they were clear, coming to rest on the armrests as he stepped in. Her freshly cleaned pelt tingling with how close the male was as his nails scraped over her thigh. Entire body tingling as his touch roamed over her thigh and down between her legs. Kneading her labia and making the digital vixen squirm as her arousal spiked hard enough to make her head swim.

Hips jumped as his hand came down with a smack, "Subject is responding well to treatment. Arousal is..." fingers spread her labia before pushing in, "I'd say a seven out of ten after only..."

The one fucking her face growled, "Thirty seconds, I'd say."

A nod and chuff, "Thirty seconds of sexual activity. It must be noted that her eagerness is markedly higher than it was yesterday." The hands cupped behind her legs and pushed them higher, cock coming down on her exposed pussy with a smack. "Will have to check to see if more code was implemented overnight, or if she is simply showing less resistance."

She would have squealed in delight as he slammed his cock into her, but the cock that was pounding her throat made the sound come out as a strangled gurgle. Eyes rolling back as the two cocks kept pounding against her, the tigers acting as if they wanted to crush her between them. Chair rocking from the force of their rutting. Low growls and huffs merging with the wet, hungry noises coming from the digimon.

Legs flexed, trying to fight against the tiger's grip so they could wrap around his waist. Wanting to feel every last inch inside her. He wasn't going to let her go, not yet and not when he could tighten his grip on her calves to really drive himself into her. Throwing himself against her, he nearly folded the digimon in half. Chair creaking as he dropped his weight on her. Just putting as much force into each thrust that he could. Measuring her response, watching how the vixen was handling what he was putting her through as he fucked her in a way that few could withstand.

Eyes were rolled back in her head as Renamon did her best to keep up with the males. Fingers tightening against one striped ass as her legs pressed to the other's shoulders. Drool was clinging to the tiger's cock as she slurped his member. She couldn't even begin to attempt to keep up with his pace as he pounded her face. Lungs were starting to ache since she couldn't breathe. The tiger had her throat stuffed to the brim with cock, each thrust smashing balls off her muzzle while his cock filled her gullet.

Her body was humming with the impacts. Each one sending raw jolts of pleasure racing through her. Orgasm building faster than she could've imagined. Between the way the tiger was pounding her pussy while he pounded her mouth, she could feel her pleasure skyrocketing. Hips jerking as best they could towards him with his thrusts before her world exploded. The lack of oxygen and injected code making her entire body jerk with the explosive force of her orgasm. Every muscle tensing and shaking as the digital vixen came harder than she could have imagined.

Just when she felt she might be at her limits, vision darkening to the point that her grip was starting to loosen, the tiger pulled out far enough for her to get a gulp of air. Body arching against him before that cock was slammed all the way down her gullet. Her tongue and throat flexed around his cock, the vixen gagging as he pressed himself flush to her lips.

Eyes crossed, focusing on his sac right as it lifted. Heavy balls drawing close while the shaft stretched her aching jaw and throat that much wider. She watched the first shot of cum as it rolled up to his base. That pulse surging down her throat, stretching her that much more before firing right down into her gut.

Hands grabbed at the male and tried to hold on as he began to pull back. Whatever whimper she might have voiced turning into a gurgling noise from the depth of his cock and how much cum was being forced down her throat. Weakening fingers trying to clutch at him as he pulled back. Feeling that flared crown as it slid up her clenching throat. Body arching up with a choking noise as he just kept cumming before that tip popped into her maw. His next shot flooding her maw and overflowing. Renamon gasping as the cock popped out of her maw, feeling the shots of cum as they rained down on her face and chin. Coughing and heaving as she tried to breath while longing to slurp up the cum as it rained down on her.

"Subject seems eager despite being denied the ability to breathe properly until she was nearly ready to pass out." The one at her head spoke with deep pants, stroking his cock before smacking it off her stained and coated muzzle.

The one fucking her had slowed down while the other finished. "Does this mean I get to finish down here?" A harder thrust drove a choking gasp from the vixen, a hand falling to press against his chest. "Seems like she's still good for a lot more." He pounded her hard and fast for few thrusts, grinning as she bounced against him while trying to clean off the cock that was beating her muzzle. "Should we move to stage two?"

"Sounds like a plan."

Renamon barely had a second to wonder what they meant before something wrapped around her. Thick, fleshy tentacles coiled around her legs and torso, lifting her up and driving her full weight down onto Tomoya's cock. She let out a breathless cry as he drove against her deepest reaches, tip battering against some barrier deep within her body. The tiger fixed her with a grin as her head rolled around limply, tendrils wrapping tighter around her, binding her hands and legs, squeezing her into a bundle he could fuck all that much harder. Hands easily sliding up and down her rear as he pounded her.

Eyes rolled back as the vixen began to gasp and huff, squirming within the tiger's grasp. He sat down on the bed then lay out, grinning as his powerful tentacles bounced the vixen over his cock. "She seems to be handling that well enough, but it's rather plain."

A weight pressed to her back, hand gripping her tail and drawing it higher. "True, but that's what lube is for, isn't it?"

There was a couple seconds where she was able to wonder about what the two tigers were planning before she felt a cock pressing under her tail. Thick, fat tip wedging itself against her pucker. Jaws closed slowly as the pressure barely registered on her senses before he was pressing in. Every muscle tensing at the invasion as her jaw dropped open with a surprised yelp. Any sound she might have made being stolen away as the thickness spread her untried rear. The cocks pressing against each other through the thinnest walls of flesh as they both drove deep.

Renamon thrashed within the tentacles that were holding her tight, the vixen's eyes rolling back in her head as jaws hung open. Gasping for air as the two spread her beyond belief. Her body somehow stretching to accommodate the two members. "Subject seems receptive," the one over her grunted.

Hands closed onto her rear, "Let us see how receptive." Tightening his grip on her, the tiger began to pound into the vixen. His cock slamming against that barrier deep in her body. Each thrust driving the air from her lungs until she could only wheeze as he delivered one hammer blow after another. Each one wearing down that muscle until he drove through with a snarl. Eyes rolling back in her head as her body was wracked with unspeakable pleasure. Code stepping in to twist what she was feeling, making her crave more even as the tiger gave her everything.

Thick seed rushed into her body. Her frame shuddering as abused muscles tried to clamp on him and draw the seed deeper. The digital female only just able to function as his cum flooded her body. Gut swelling to the point of making her look several months pregnant within mere seconds.

She was steadily losing her mind as the tiger filled her to this point. Mouth hanging open and eyes rolled back in her head, tongue dangling from her maw. Body rocked from male's thrusts against her backside. Ass clenching around his cock like a vice as he drove against her. She grabbed at the vines for something to hold onto as she tried to process it all.

"Are we breaking her already?" a voice growled into an ear. "Is it too much for the vixen slut to handle? I wouldn't have thought she was this weak."

Pride flared within her and the vixen shook with a snarl. Shaking herself out of that freshly fucked stupor as the male under her pulled out. Tentacles flowing from one tiger to the other so she could stay bound. Body exposed to the tiger as he split forms again. She growled and pulled against the grasping tendrils, somehow managing to grab at her own ankles and pull them towards her ears, "That..." she growled, "all..." a grunt as the male in her ass pounded deeper, "you got?"

It seemed that pride goeth before the fall. A wide grin splitting the striped male's face unnaturally wide. A stretch turned into more as his body split, forming into another of his clones. "Well," the one male rubbed his softening cock to breath life back into it.

"Let's give the lady what she wants," the other growled lustily as he stepped forward.

She found herself and the male under her pulled to the edge of the bed. Letting his feet brace on the edge of her bed so the ass-tiger could keep pounding her harder. The new copy stepping in and bringing his cock down on her drooling, gaping cunt. Despite the fact that her pussy was still leaking copious amounts of the tiger's seed. "Hey, Stripes!" she snarled over her shoulder, not looking away from the tiger as he lined his cock up with her twat, "Let me go so I can fuck you right."

The one over her leaned forward, "Sounds like a challenge." She held his stare with one of her own, the vixen's head rolling back as those tentacles pulled away. One leg falling onto his shoulder as the other draped over his hip before pulling him tight. Groaning as the thick cock speared into her, mix of cum and pussy juice wetly squelching around his member.

Her tongue flicked over his chin, "Bring it, Pussy cat."

Bracing her hands on his shoulders, the digital vixen did her best to pull herself between the males. Hips lifting into the one over her before driving back into the one under. Ass stretching further than she'd ever imagined it could. Not that she'd imagined it could've stretched very far, since she hadn't even pondered having something in there before. But that was all an aside. Nails dug into his shoulders as she pushed herself between the males. Twisting, rolling, bouncing, and snarling the as she took the two tigers.

Except there were three. No sooner had the one forgotten tiger came around the side of his clones than she struck. Hand snapping away from the pussy-tiger's shoulder to curl around the newcomer's cock. Smoothly teasing his tip and shaft as she began to pump him. Coaxing him closer to her maw as he moved around until she could twist. Lips sealing around his tip with a hungry growl. Tongue wrapping around his tip and teasing the crown before she drove herself down a few inches. Hand flying up and down over his shaft as her once pristine body writhed between the trio like the hungry cock-whore she was becoming.

They'd only just gotten started when a fourth tiger showed up. She felt him forming before she even saw him. Feeling how the bed shifted under the weight. No sooner had the male's length formed than her hand was wrapped around it. Feeling its weight and heft as her hand flew over the spire.

A surprised noise came from the streak of tigers as she so eagerly went to work. Hips rolling this way and that, gyrating wildly as she pounded down into the male beneath her. Using the rebound of his thrust to slam up into the male over her. Breasts bouncing wildly with each revolution as she was knocked up and away from the males. Driving her maw down the cock before her. Using her handholds to draw herself back into balance, legs tightening their hold and muscles clenching. Hands flying up and down the two cocks as she coaxed out delicious precum.

Hips slammed up against her, heavy balls drawing tight against her taint. The vixen meeting the thrust by driving her own body down. Grinding into his lap as the male peaked. Cum filling her backside, threatening to swell her further, but without a hungry womb to catch his load much of it began to leak out around the base of his length. That wouldn't stop her from grinding against him though. Rear pressing down into his body sharply as her insides trembled.

"Subject is showing renewed vigor now that her abilities have been challenged." The cock slipped out of her rear as they shifted again, cum pouring from her stretched rear. Strong hands guided the vixen around until she was kneeling on the bed. Two tigers before her as the one under shifted. "Now the stress test can begin in earnest."

From the corner of her eye she saw the two males that had been plugging her bottom holes begin to shift. Their forms flowing together, but instead of turning back into the same Tomoya she had been experiencing, this one grew. Body shifting larger and larger until he towered over them, cock growing at the same rate that his body was. For a second, Renamon knew true fear as she watched him stroke that glistening length with that savage grin of his.

Then she pulled off one cock, drove her muzzle down the other, and simply hiked her tail up in challenge. Every inch of her body screaming for him to try and break her if he could.

If anyone was up for the challenge, it was this shape-shifting tiger.

Her eyes shot wide as his cock pressed against her. It had been large before, but now his tip felt like a fist that was being pressed to her pussy. Even stretched and used as she had been over the past day, she knew it was too big. Some instinct screaming at her to try and get away. That stubborn pride of her made the vixen arch her hips and rock back against him. Bring it, she told him with her body, she could handle everything he threw at her and more.

If it hadn't been for her programming, and the cock buried in her maw, she would have ground her teeth as the male pressed into her. Breath came in shorter, sharper puffs as the male forced her pussy to stretch ever wider. Her code scrambling to keep up as digital flesh was spread over the fat head. Precum mixing with the general mess that oozed out of her to help.

Tomoya's growl shaking through her body as the male rocked his hips slowly. Pushing just a little of his tip in before drawing back. Deeper then back. Her body steadily losing resistance as he forced her open. That cock pushing deeper with each slight rock until...

"FMMMK!" she grunted around the cock, eyes rolling back again as the male forced his tip in with a jab. Thighs quaking and every limb threatening to give out as he pushed deeper. Her stomach distending around the size of the male behind her. She shook on his length as the not-so-simple act of penetration pushed her over the edge. Walls clamping and rippling as she came around him. Hips shaking before her eyes rolled forward, focusing on the males before her with a determined growl.

Drawing her head back, the vixen focused on the other male again, pumping the one she had been sucking as her form rocked back. There wasn't much she could honestly do other than make her hips jostle back slightly. It was enough to let him know that she wasn't giving up yet. He was stretching her far enough that her pale belly fur was shimming with the blue energy of her data as he pressed deeper. Code and stubbornness trying their best to keep up with the sheer size of the tiger behind her. Tail falling to her back as his heavy hand closed around her hip. Drawing the vixen back into his thrusts, almost using her as a cock sleeve over his length.

A chuckle sounded from the male in front of her, "Too much?" Tomoya ruffled her hair as one of the males before her flowed into the other.

For a second, she was worried he'd grow to the same size as the male behind her. He did grow larger, but not to that gargantuan size of the one behind her. She drew back as his cock expanded before her, easily doubling in size. Reaching a point where her fingers couldn't meet as they stroked him.

Rather than pull away, she braced her arms against his thigh and brought both hands up to toy with his flesh. Tongue bathing his tip as she wheezed, "I'm taking it, aren't I?" Grinning at the male as the next thrust drove the breath from her. Cock spearing deep enough that she was certain he knocked her diaphragm. Eyes crossing for an instant before focusing on the one in front of her. Head angling so she could let her tongue glide over his flesh. Lips stretched as she forced her own muzzle around him, jaws stretching nearly to their limit as the vixen began to bob hungrily. Growling hungrily around him as her head bobbed over him.

She had to fight to keep her footing as the male behind her began to thrust. Each pump nearly driving her nose into the male before her before almost ripping her off the cock. Muscles stretching around his length, gripping him like a vice despite how slick she was. She voiced a growl and wrapped an arm around the male's waist. Feet digging into the bed as she lifted herself higher. Burying her head into the male's lap as she sucked on him hungrily. Gladly choking herself on his cock as her neck stretched around his girth.

Not one to back down himself, the two Tomoya held onto the vixen. One cupping her head and the other gripping her middle. They began to thrust into her. Both using the vixen as if she were little more than a toy. A toy that could squirm and writhe between them. Tongue and muscles coaxing over their cocks as she fought to keep her footing. Not wanting to back down or balk after the challenge to her capabilities. Though she wasn't sure if she could handle much more beyond this. It wouldn't stop her from trying though.

The trio growled, grunted, and gurgled as they rocked. Renamon doing her best to pleasure the male before her. Barely able to draw back enough to tease his crown with her teeth before the next thrust buried her nose into his groin. Tongue darting out to tease over his balls as they churned with seed. The shape-shifter seeming to have a near limitless supply of the stuff as he split and reformed and altered himself.

Breaths started to come heavier as the males drove against her. The resilient, stubborn digimon refusing to give them even an inch. Somehow challenging them even as her body was pushed to its limits. Eyes rolling back in her head as the sheer size of the male fucking her pussy forced her from one climax to another. Legs shaking and threatening to give out only to bolster themselves at the last instant and keep pressing back. Her legs swaying, toes only just brushing the bed as the massive male leaned over her with a snarl. That massive cock pulsing as his wrecking balls lifted slowly.

He came with the force of a tsunami. A tidal wave of cum blasting her, stretching her gut to the point that it began to sag after the first blast. Renamon's hands scrabbled at the male in front of her, almost seeming to work on automatic as her tongue lashed over his spire.

The male in front of her wasn't far behind his companion. Drawing back until his tip was just barely resting within her maw before cumming with nearly the same force. She managed a quick gasp of air before pressing down. Letting some pour right down into her belly, making the digimon look as if she were pregnant with an entire tribe of hybrids. Drawing back, she gasped and happily let the cum run over her face and front. Matting her once clean, floral scented fur with that heavy cum.

Renamon huffed at the tigers, having to reach up to wipe her eyes clean before she could even look at the tiger. Glancing back over a shoulder as the male pulled out slowly. Teeth gritting as her insides tried to keep him within her walls before he pulled free with a wet pop. Her thighs shaking as she came again, falling to the bed with a gasp as cum poured from her stretched frame.

"Mmmmmmpppph," she groaned into the bedding, gripping tight as the males moved to stand at the foot of the bed. A low huff slipped out of the vixen as she sat up slowly, body still shaking as she panted, "That... that all you got?" One of her legs gave out, all feeling gone, dropping her onto a seated position. She panted and grinned at them slowly, "Cause I've still got more in me."


Tomoya looked over the footage with a hum. For the first time in a long while he felt tired. And just looking at the security feed showed why. Two of his clones were in the room with Renamon. One pinning her to the bed with his body, cock pounding between her breasts. Fingers playing over her nipples and pulling, drawing up beads of milk from the vixen. She looked more white than yellow currently, cum clinging to her fur once again. Another had her legs braced against his chest as he pounded away at her pussy. "So what up time are we looking at?" he asked over his mug.

One of the techs quickly brought up a window, "We are looking at one hundred and ten hours, fifteen minutes, and forty seconds on my mark." A brief pause, "Mark."

"So," he began slowly, "Not counting brief periods to sleep when she was too physically exhausted." Fingers lifted to count off each instance. "Time spent cleaning her up, and brief meal times. She has been going for a week without stop."

A moment of hesitation, "We logged some of the meals and showers under the up time as well, sir. Each time your clones back off, she just seems to get a burst of energy and challenges them again."

He knew this all too well. Some of those times a rest had been called for hadn't been because of her. There was a reason he was out here right now. A bit of sleep, even as his split-copies kept going, was needed even for a shape-shifter of his caliber. "Yes she does, and she's very good at what she's doing. Have there been any further alterations to her code since we began?"

The raptor pushed up her glasses, "Ah, we have several updates that have been queued up to be implemented for testing, but they've been on hold until the stress test had been concluded." Talons clicked off the keys as she scanned the reports. "There has been a change to her code, but it seems to be one that she has implemented herself." Tap tap. "By our estimates it seems that the change is biological in nature. I hate to draw conclusion without properly testing or observation, but..." she puffed a breath slowly.

"But?" Tomoya arched his brow. She was looking over the alien programming language, finger tapping her lips in thought. "If you had to make a guess?" he said a bit louder.

She jumped, "Oh, sorry I was just double checking. If I had to make a conjecture based off current observations and actions." A clicking noise rolled up from the raptoress as her feathers flared then lay flat as she rolled the very idea of what was happening around in her head. Tomoya clearing his throat to remind her of the question. "Right! Sorry. If I had to venture a guess I would postulate that, for lack of better terms, she's pregnant. Gestation is currently unknown though."

"Well," Tomoya chuffed, a smile splitting his lips as he leaned back. "Well that is an interesting development now isn't it?"

The raptor puffed her cheeks and trilled, "An expected one. Well, expected if she were flesh and blood, but for a digital entity..." she trailed off as she watched the code again. "Can't wait to see how it develops." eyes darted from the screen to the camera feed again. Biting her lip as she squirmed a bit.
