Mods Make Everything Better

Commission for Draegon1993

“Anthony!”

He tried to ignore it. He had just gotten off of work, was already on his way through the parking lot, and had no intention of slowing down. The day had been tough enough, and he was ready to just get home and relax.

Maybe if I pretend I don’t hear it, he’ll just give up…

“Hey, Anthony!”

Dammit…

The voice was closer this time. Whoever it was that was trying to get his attention had to be running or something. He wasn’t going to be able to make it to his car before he was caught up to.

Reluctantly, he turned spotting a co-worker jogging in an effort to catch up with him.

“Patrick? Uhh, what’s up?”

The other guy trotted the rest of the way up to Anthony, a bit out-of-breath, “Hey man… -huff- hold up… -huff- a sec, please…”

Anthony wasn’t particularly surprised that the other man was so out of breath. Patrick worked on the fifth floor, and he was not particularly fit.

“Are… you okay…?”

The other guy held up a hand and nodded, “S-Sorry, -huff- was just… -huff- trying to catch you, -huff- before you… -huff- left for the day…”

Anthony knew Patrick fairly well, he was a nice guy, but a tad on the wimpy side. “You could have just called me, you know. You didn’t have to run down 4 flights of stairs…”

Pat finally looked to be catching his breath, “You’ve got one of those, um… synthetic… cyber dog… things… right?

I rolled my eyes, “I assume you mean a Saiber…?”

“R-Right… that.”

They had hit the market about a year ago, Synthetic Artificially-Intelligent Bio-Electrical Robot, or “Saiber” for short. Basically… they’re robot pets, just highly sophisticated and adjustable. Most people tend to get them for companionship. They act pretty identical to actual pets, just without the need to groom, feed, or clean up after.

“I just wanted to ask about them. How expensive are they? Are they really as low-maintenance as the ads say? And they make good guard dogs, right?”

Anthony was a bit surprised, as far as he knew, Patrick was adamantly against fake pets, as he always put it. “Huh? Well, uh… mine was right around a thousand bucks, and… Wait, didn’t you say you’d never buy one of them? You said they were a ridiculous waste of money…”

“Heh… well…” Patrick rubbed the back of his neck nervously, “The truth is… there’s kinda been a string of burglaries in my area… a couple even in the same building that I live, so I’ve been thinking of getting one… y’know, as a guard dog.”

“Oh…” Anthony stopped to think for a second, trying to recall where the other man lived, “You’re uh… right off of 7th street, right?”

Patrick nodded, “Yeah, corner of 7th and Barney. Hey, you live pretty close by there too, right?”

“Y-Yeah…” Anthony nodded, doing his best to not show that he was actually a bit bothered. If Patrick was at risk of being burglarized, then logically, he was too, and despite being a little over six feet tall, and in pretty good shape, he wasn’t particularly confident that he could hold his own against a possibly armed thief.

“I bet you’re glad you have one of those cyber things to protect you.”

“Err…” Anthony had to think for a second to push the thought from his mind, “Uhh, right… yeah, I guess they’re pretty good as guard dogs, if you get the right mods.”

Patrick looked at Anthony with a bit of confusion on his face, clearly not really knowing what the other man was talking about, “Uh… mods…? I thought they were kinda… real, or something…”

Anthony sighed, “They’re synthetically organic. They can be programmed to change size, shape, and personality. So, if you buy, like… a… Doberman mod, and an AI pack that makes it fight off burglars or something…”

“Oh, uh… I think I get it…”

Anthony kept his eyes on Pat’s face as he tried to make sense of the information, seeing that the puzzled expression was not fading in the slightest. It was becoming fairly clear that explaining everything to the older man was not going to be a quick conversation.

“Tell you what, I’ll bring in all the info that I have tomorrow, and give it to you at lunch, sound good?”

“Oh, that’d be a big help! Thanks!” Patrick began to turn, to head back in to the building, but stopped short, one more thing to say, “Guess I gotta admit, you were right about these fake pet things, your place is probably super secure.”

Anthony held up a hand, “Heh… y-yeah… I guess I’ll see you tomorrow.” Without even waiting for a farewell from the other man, Anthony turned, and once again began walking towards his car at a fairly brisk pace. He was just as eager to get home as he was before, except now, he had an additional issue on his mind. As much as he was trying to force the thought out of his brain, Patrick had gotten the idea weighing on his mind.

He really doesn’t live that far from me… If he’s at risk of being robbed, then so am I…

Just as Patrick had assessed, Anthony did indeed have a Saiber dog, although, it wasn’t quite as he expected. Anthony knew an okay amount about the mods and enhancements that were available for Saiber pets, but that didn’t mean that he actually had any of them…

As much as Anthony didn’t want to, he let the conversation linger on his mind, even as he made it to his car, and headed towards his apartment.

~~~~~~

“Maybe Patrick was on to something…” Anthony spoke out loud to no one in-particular as he sat in his living room, looking at his computer. Upon getting home he had immediately started checking into the exact same thing that he was talking to his co-worker about a short time ago, “I mean… maybe Roller could stand a mod or two…”

(BARK! BARK!)

At hearing the familiar sound, Anthony glanced down, smiling as he saw Roller, his Saiber pet, trotting up.

“No offense buddy, but I don’t think you instill a lot of fear in people.”

Anthony petted the small cyber dog, as it looked on with its tail wagging. Roller was still in its default appearance, which was that of a small Yorkie, chosen because it resembled his childhood dog. Like most Saiber pets, it looked, felt, and acted just like a real dog. Its bio-organic “fur”, though still soft, had a bit of a metallic sheen to it, and its eyes often showed a bit of a glow, but other than that, Roller looked very similar to a regular dog.

Roller had the default “Companion” AI pack installed, meaning it was exceedingly friendly, the complete opposite of what someone would want as a guard dog… not that Anthony had any complaints about that, Roller being a guard dog had never even crossed his mind in the past. All Anthony had wanted was a companion, and with the apartment not allowing pets, or rather… real pets, it seemed like an obvious conclusion.

“Alright… let’s take a look at what kind of money they want…” Anthony brought up the official Saiber website, and navigated through to find the section titled Mods and Upgrades.

“Let’s see… Aha! Found it, the Devoted Guardian AI download. Current version is 3.7, perfect for protection and security, and 100% loyal.” Anthony read the description on the page as he scrolled through looking for the price, “Let’s see… 750 terabyte download… for best results, use with Doberman or German Shepherd canine body modification… price is… Holy shit!”

Anthony’s jaw just about fell off of his face as he stared at the screen, the price of $3,500.00 listed on the screen was far, far more than he had expected.

“Three-and-a-half grand!?! And it doesn’t even include the mod?!? What the hell!? For that price, I might as well get a whole new Saiber!”

(whimper…)

With another glance down at his pet, Anthony reached in and patted Roller on the head, “Don’t worry buddy, I’m not replacing you.”

Anthony, of course, didn’t have any intentions of getting a new Saiber pet, but if he intended to buy the new AI pack, as well as the mods to make Roller look a bit more fearsome, it would indeed end up costing close to the same amount as if he were.

“Well, that plan’s out the window…” The 25-year-old sat back in his chair, at a loss for what to do next. He looked back towards the screen, and caught sight of a different line on the same page.

Use only officially licensed Saiber developed software to modify Saiber products.

It struck Anthony like a punch to the face, “That’s right, it’s just software… Odds are, someone on the internet has it for a hell of a lot cheaper than here…” He brought up a search engine and typed in a few key words, it didn’t take long before Anthony was literally looking at a list of mods and AI packs, most of them tagged as either ‘cheap’ or ‘free’.

“Oh, hell yeah… Now we’re talkin’.”

He scrolled down the list excitedly, all of the possibilities seemed to be there, it was looking like he could get any AI pack, and any dog breed… hell, any animal breed that he wanted, the only caveat being that nearly all of them were custom-made, or at the very least, altered versions of the real software.

“Hey, this one looks cool… Dominant Ruler, it says that it’s a customized version of the Devoted Guardian AI, and it comes with some mod called… Emperor Equinine…? Never heard of that breed.” Anthony clicked on it checking the description, “Someone apparently took the guardian AI, tweaked the aggression, ownership, and authority way up, sounds perfect for keeping the place safe! What do you say, Roller?”

He turned to look down at the small pet again, once again, receiving a tail wag and a cheerful sounding bark in response.

(BARK!)

I mean, worst-case-scenario, I just factory reset, and revert back to Roller’s original settings, right?

Anthony thought it over, knowing that he had a fail-safe just in case something went wrong, was very comforting, and thus, he didn’t hesitate to click the confirmations, “Establish link to Saiber product” and “Begin Download”.

Roller’s eyes began to glow a light blue, signifying that the connection had been successful, and the new software was downloading. Anthony was familiar with the glow, as he had seen it whenever Roller had to download a stability update or something, but something about it this time, just seemed so exciting. He watched intently, as he knew his pet was about to start to change physically.

It started up right away. Roller stood completely unmoving as his AI updated, and it became immediately noticeable when the small dog’s form began to change.

Anthony’s eyes widened in excitement as he watched. Roller’s limbs grew longer, his body grew bigger, muscles began appearing where there were none before. Almost immediately, Roller was no longer recognizable as the Yorkie he previously was. Anthony tried his best to make out the features of what breed Roller looked to be reshaping into.

“Looks like… Oh, a German Shepherd… Is that what an Emperor Equinine is supposed to be…?

The blue glow in Roller’s eyes flickered a bit, enough to catch Anthony’s attention, he glanced towards the dog’s face, just in time to see the glow turn off completely, and growth of Roller’s body seemingly coming to a halt.

“Shit… don’t tell me…”

Anthony hopped out of his chair, and moved to kneel in front of his pet, checking to see if it was still responsive at all. He moved in close, looking for even a faint light in the dog’s eye, and as soon as he was basically face to face with his faithful pet, the blue glow returned, abruptly enough to make the human flinch in surprise.

Oh yeah… things reboot during updates, duh…

The answer dawned on him almost immediately, and just as he went to stand back up, he felt Roller’s paw extend, and contact the middle of his chest. Anthony didn’t even have time to prepare himself before he felt the force of Roller pushing him backwards.

“Whoa! Oof!”

Anthony landed on his back firmly, and right away Roller placed his forepaw onto the human’s chest, holding him in place with strength a hundred times greater than the old Roller possessed.

“H-Hey, Roller… what are you -ungh- doing…?” He struggled under the dog’s forepaw for a moment, but it didn’t long for Anthony to come to the realization that he wasn’t going to be able to move, as long as Roller was holding him in place.

The paw was very firmly in place, but there didn’t seem to be any unnecessary force behind it. Roller was intentionally holding Anthony in place, while making sure not to actually hurt him… not that that made it any more clear what Roller was even doing, though…

Anthony remained still under his pet’s foot as it seemed clear that the dog’s actions were not malicious, and remained still, even after the paw holding him down seemed to relax. Which is when Roller decided to continue on with whatever plan he had. He stepped forward, and continued moving over the human’s body, eventually reaching the point where he was actually standing over his owner’s face, giving the man a full view of an unexpected new addition to Roller’s form.

“W-Whoa… What…?”

Protruding from Roller’s underside, as impossible as it seemed was a dick, which was a feature that Saiber Pets did not generally include… It looked exactly as one would expect a canine’s dick to look, except for the fact that had a blue glow to it, much the same color that his eyes glowed at times.

Anthony stared in complete bewilderment as his pet took another step forward, bringing the glowing organ even closer to his face.

“N-No Way! Did the mod do thi—GLLLK!” As if he was intentionally taking advantage of the human’s open mouth, Roller moved swiftly, shifting his position, and jabbing the tip of the newly formed organ past the spread lips.

The mod gave Roller a dick?!? What kind of pervert made this?!?!

At first Anthony was assuming it was simply incidental, but as the organ idled inside of his mouth, it started to set in… it was deliberate. Whatever AI software that he had just installed had drastically affected Roller.

The fact began to set into Anthony’s mind just as Roller started moving. At first it was just the tip of the blue member that was resting against his tongue, but every slight motion from the dog seemed to push the organ further into his maw.

Anthony struggled, flailed, and even tried to call out, all to no avail. Roller was borderline thrusting into his face, and with every passing second, the dog seemed to be getting rougher, deeper, and even… bigger?

(Rrrrrrrr….)

The growl wasn’t a ferocious growl, it felt more… impassioned, as if Roller was getting into it. That didn’t make sense though… a Saiber Pet getting turned-on…?

Roller’s tip began bumping into the back of the human’s throat, and even trying to breach even further. As unlikely as it felt to Anthony, his mouth was somehow containing the new appendage of his pet, to the point where Roller’s newly-formed, billiard-sized balls were striking him sharply in the chin.

This… this can’t be actually happening…

Despite actually experiencing it, Anthony refused to acknowledge that he was more-or-less getting face-fucked by his dog. He could feel the texture of the cock as it slid back-and-forth over his tongue, he felt the weight of the testicles as they bounced off of his chin, and he was also beginning to notice the feeling of slick fluid, not only filling up the free space inside of his mouth, but also leaking down his throat.

“GLLK! -koff koff- AAAACK!”

The human gagged and choked out coughs around the glowing dick as pre flowed down his throat. Thankfully, it appeared that Roller took that as a signal to back off a bit. Anthony struggled to try and suppress his gag reflex, as he watched the long spire pull smoothly out from his lips. He was even able to feel the surprisingly viscous fluid continue to spurt from it all over his tongue, and even as the tip pulled free, it continued to flow, splattering and oozing down the human’s face.

“PPPPFFFF! AACK! -koff koff- GAAH!”

Anthony turned his head and closed his eyes, which was more-or-less all he could do to shield himself from the copious amount of pre that his face was being bombarded with.

“Unngh… -koff- Roller, I think you -koff- y-you…” Anthony stopped mid-sentence, as he turned his face back forward. Roller had backed away from him a few more steps, which finally gave the human a full view of his pet’s new form.

He hadn’t been mistaken when he thought he felt that Roller was still growing, even throughout the face-fucking he had just received. The once-small dog had not only completely taken the form of a German Shepherd, but he had to be over five feet tall at the withers, and didn’t look to be finished growing yet.

“J-Jesus… Roller, is th-that you…?”

Anthony climbed to his feet, just as Roller began trotting forward, and with each step, it almost felt to the human that he grew slightly taller. He had never imagined that he could be standing up straight and be at eye-level with his dog.

Anthony was near frozen with shock… that is, until he let his gaze drift downward, and caught sight of the organ that he had very recently become very acquainted with. As it had been in his mouth, he hadn’t really gotten a full view of it, but now it was on display in front of him, and it was clearly getting larger, just as the rest of his body was.

I had THAT inside my mouth?!?

Roller’s dick looked to be pushing a good 10 inches or so thus far, and was nearly as thick as a soda can, but the thing that really took Anthony by surprise, was that the head of the organ looked to be wide, not unlike what one would expect to see on a horse. It was, to say the least… intimidating…

Anthony instinctively took a step back, feeling his heel bump up against something. He turned to see that he had apparently misjudged his position in the room, and bumped into the back of the couch, a fact that Roller quickly took advantage of.

The dog took a couple more paces forward, reaching his owner even before the human had a chance to turn his attention back. Anthony, once again, looked into the eyes of his pet, needing to tilt his head upwards a bit to even do so.

“R-Roller, heh… You’re getting a little big there… How about we—WHOA!”

It’s as if he knew that the human was considering resetting the changes, and was not about to let it happen. It took little more than a quick swipe of his forepaw to turn the human around, and then using the same pressure that he had used against Anthony’s chest earlier, he began pressing against the human’s back, easing him into a bent position over the back of the couch.

(Grrrr…)

Roller’s growl was low, not particularly threatening, but definitely dominating, if nothing else. It felt to Anthony, like he was simply asserting his position in the developing situation. Either way, it sent a shiver through the human, and if nothing else, sent a clear message that he didn’t want his owner to move.

It was as if the roles of the two had reversed as Roller removed his paw from Anthony’s back, and the human obediently remained in place over the back of the couch.

The paw moved slowly from Anthony’s back, and caught the back of his waistband. One downward tug was all it took to get the man’s pants, along with his boxers, down past his knees, leaving his behind bared to the robotic canine.

“Ah! R-Roller! N-No! What are you—”

Anthony almost pulled himself up from his position, but Roller took a heavy step over the back of the couch, and synchronously, over Anthony as well. The big canine leaned in close over the human’s back, easily big enough to reach his owner’s ear with his muzzle, and let out another low growl.

(Grrrr…)

To Anthony, it sounded more like a purr than a growl, as if Roller was more amused than anything else. Though, with the powerful dog on his back, it wasn’t as if Roller’s amusement changed anything. Either way, he wasn’t going to be able to move.

He knew it was inevitable, but it still caught him off-guard as he felt the big organ begin to bump lightly against the back of his leg. It was just as warm as it was a moment ago, and left a slick trail going up the back of the human’s thigh, as it slowly rose, aiming towards Anthony’s tight opening.

“Thiscan’tbehappening… Thiscan’tbehappening… Thiscan’tb—GEH!”

Anthony was repeating the words to himself, hoping that it was, somehow, all a dream, or a joke, or something. Feeling the slick, wide head of the cock finally tip against his ring, snapped him out of it real quick.

(Grrrrr…)

Another low growl, and there was no question this time, Anthony heard it simultaneously as he felt the pressure begin behind him. Roller’s tip, by all means, should have been too wide to fit inside him, but right away, the human could tell that that wasn’t going to be the case. It almost felt like slow motion as the wide head of the blue spire, still liberally leaking pre, nudged forwards, and slowly breached the too-tight sphincter.

“Oh—hhh G-GOD!”

The head popped in with a slight slurping sound, and Anthony could immediately feel the warm pre splash against his insides.

(Rrrrr—ahhh…)

The growl came from over Anthony’s head, Roller was still growing, and the human was feeling every bit of it.

Roller’s movements were not subtle, just his first thrust buried several inches of the glowing organ inside of Anthony’s tight tunnel, making the human feel fuller than he ever had before.

“Hnnnghhh… Ghhhaah… R-Roller…”

Anthony gripped the couch tightly, his nails dug into the fabric almost deep enough to tear it. It was pretty much all that the human could do to endure being speared into so roughly by his pet. Even as he was being invaded by the massive shaft, he could feel it spreading him wider still. As each second passed, Roller was still growing… The dog had to be nearing the size of a horse at this point, with a cock to match.

** THUMP THUMP THUMP **

Roller began thrusting properly, exerting enough force to make the couch actually pound against the ground. Without any regard for the human underneath him, the dog jammed himself through the tight tunnel, burying his thick length as far as he was able to. Pre continue to coat Anthony’s insides further lubricating and slickening the narrow space, so even as Roller’s size continued to increase, he was still able to pound himself in further.

Anthony couldn’t even bring himself to make a sound. Not that he had anything coherent to say. Roller was reaching so deeply, the human was feeling things that he had never even thought he was even capable of feeling. He had been reduced to nothing but a mess of carnal instinct, and the feeling was nearly euphoric.

Roller pulled back, and slammed forward again-and-again. Every forward thrust was deep enough to make Anthony’s belly distend just due to the size of the organ, and every back thrust caused more pre to escape, and slowly cascade down the back of his thighs.

“O-Oohhhh…”

As surprised as the human was at the turn of events, he was even more surprised that he was actually enjoying it. No, it was more than that… he was loving it… his moans an attestation to that. He was enduring the pain of having something so huge spreading him so wide, but alongside the pain was that magnificent full feeling. Roller was already inside of him far deeper than what should have been possible, and all Anthony wanted was for the dog to get even deeper.

A few more unrelenting thrusts, and there was still no sign of Roller nearing his climax, though the same could not be said about Anthony. His erection throbbed with need for release as each of his pet’s thrusts made it rub against the couch. He was already nearing his own climax, largely from the giant dog dick sawing through him.

Fuuuck… I’m gonna… g-gonna cum from this…

It was as if Roller’s movements were on cue with the man’s thoughts. With a shift of his front paws, the dog’s angle changed, and with one more sharp push, he hit a spot inside of Anthony that set of all sorts of fireworks in the man’s mind.

“GGHHHHAH!”

Anthony’s orgasm hit, and pleasure unlike anything that he’d felt before surged through him. He squeezed his eyes shut and let loose several spurts of his seed onto the couch under him.

All but lost in the bliss of climax, Anthony almost forgot about the fact that he was still getting ravaged by what had to be a foot of synthetic dog cock. Roller’s pace had even increased, and it seemed that there was still more of the impossible organ to go. Despite Anthony’s already tight passage tensing up even more upon the human’s climax, Roller still managed to keep slamming further in, seemingly determined to sheathe his entire shaft inside of his owner, a task that Anthony never would have believed was even possible…

…until he felt the canine’s knot begin to collide with his ass.

No way… n-not possible…

Anthony dropped his head down to get a look at his gut, and just as he expected to see, his pet’s ridiculous size was bulging him out even further, the protrusion caused by Roller’s length was nearly as far up as his chest, and pressing so strongly, that the blue glow of the shaft could be faintly seen, even through the human’s skin.

Roller was as deep as possible and still trying to get further, slamming into Anthony with immense strength. Doing all that he could to, somehow, get a knot that felt like it was the size of a cantaloupe to fit past the stretched ring.

** PLAP PLAP **

The sound of the dog’s testicles slapping noisily against Anthony’s thighs added to the cacophony of sounds emanating from the apartment. Roller growled, Anthony moaned and whimpered, the couch banged against the floor, it was a miracle that no one had complained yet. Although, even if they had, stopping wasn’t really an option for the duo.

(Grrrrrrrrr…)

The growl was determined, something was going to happen, and even Anthony knew it. He grit his teeth and steeled himself as Roller strengthened his onslaught.

“FF—UUUUUUCK!”

It seemed impossible, but Anthony could feel the fat flesh bulb beginning to open him up. The cyber canine’s thrusts turned into slams. Pre squirted out around the fat knot every time Roller tried to power it into his human. Every gyration worked it in ever-so-slightly, until eventually the human’s ring of muscle reached its limit, and that massive swollen knot was locked in-place.

(Rrrraaarrrrooooooooooooooo!!)

Roller let out a howl as he sank fully into his human, and not a moment later, Anthony felt exactly why. Waves of what had to have been synthetic cum blasted into the human’s bowels. Warm and heavy, the fluid weighed heavily inside Anthony, and he was hit with the filling feeling that he had discovered earlier except much moreso.

It felt like punches coming from the inside of his gut, each individual shot of Roller’s eruption felt more powerful than any orgasm that Anthony had ever experienced. His insides were battered with the fluid, just one blast felt like far more than an imaginable amount.

Anthony lowered a hand to feel his gut.

Holy shit, how much is he filling me with…?

His fingers ran over his belly, right away feeling the protrusion caused by the massive cock that was locked inside of him, but what he was finding more alarming was the steadily expanding bulge that was quickly growing large enough to even obscure the impression of the hard spire in his midsection. Anthony could feel every pulse of the Saiber Pet’s organ, and each one was accompanied by another swell of his already over-bloated abdomen.

It went on for close to a full minute, and Anthony took every bit of his pet’s output, the knot preventing any of it from escaping. Hand on his gut, he could feel himself gradually rounding out, and by the time Roller’s orgasm started to cease, the human’s midsection looked as though it contained a large watermelon.

(Rrrrrrr…)

Roller’s hips slowed, and eventually came to a stop, he let out the satisfied noise, and relaxed himself a bit, even beginning to lower himself to the ground, of course, still tied to his conquest… which in-turn gave Anthony little choice but to go down with him.

“Aack! R-Roller!”

Thankfully, the canine brought himself down gently enough to make it not-uncomfortable for the human that was attached to him. The horse-sized cyber animal laid down on its side, foreleg draped over Anthony’s torso.

Anthony glanced back-and-forth, finally deciding that the ordeal was actually over, he took a deep breath and laid his head down doing his best to repose himself in the position that he was in. Luckily for him, the exhaustion was already beginning to set in, which proved to be a great aid on that front. He barely had to make an effort whatsoever, before he succumbed to fatigue-induced slumber.

~~~~~~

** tug **

“Huh…? What…?

** TUG **

Anthony was snapped out of his slumber abruptly, feeling the sharp pulling from behind. It took a moment for the human to discern what it was, in his state of bewilderment, but as the consciousness of his recent experience began to return to the front of his mind, he caught on fairly quickly.

Roller had a large paw on the human’s back, pinning him to the floor, as he gave fierce pulls, assumedly attempting to remove his knot from Anthony’s insides.

(Grrr…)

A determined growl, and Anthony could feel the paw against his back tense up slightly. The still-too-big knot throbbed against his prostate, sending one more tremor of intensity through him as Roller drew back once more.

** TUG **

** POP **

“GGHHHHAAAAH!”

A particularly sharp tug was enough for Roller to free the massive flesh bulb from the clutches of his owner’s backside. He backed himself out, dragging the entirety of the thick length out, slow enough for Anthony to almost think it was intentional.

Over a foot of recently formed cock slid out from the tight tunnel, followed by a gush of the cyber dog’s glowing blue seed, the feeling of the rush through his system was enough to set the human off one more time, bringing him to orgasm as he slumped to the ground with a euphoric expression on his face.

Apparently satisfied with the final outcome, Roller began to trot away, his organ still unsheathed as errant drops of the viscous blue fluid slid down the length of it.

“Wow, that… that actually happened, didn’t it…?”

Anthony spoke aloud to no one in-particular as he glanced downward, taking note that the amount of the cyber animal’s discharge flowed out of him was enough to form a small pond around his body, and despite that, his midsection still showed a noticeable swell, just from the amount that remained inside of him.

Anthony let out a contented sigh, “I think that mod… was a good decision…”
