Ultra-Virilizer
🕑 Added 2024-10-10 11:53:28 +0000 UTC"Hey, deal with these, I made way too many," Jack dropped a handful of pills into your shirt pocket the instant you opened the front door to her, sneaking past and crashing on the living room couch. "Sorry to skip the formalities but my house is so saturated with pheromones I was never gonna be able to even -think- there." She took a deep breath, sucking everything in and undoing the button on her tight jeans, unzipping and letting a cock that dangled somewhere around her knees flop out.
"God, I got so much bigger none of my pants fit at all. But if you've got any questions before I use your shower, I'm not a -complete- bitch." That might have been a lie, but she did like you enough to not want to just bowl you over... in that way.
You blinked as your nose wrinkled at her scent. The shark smelled MUSKY. In fact your friend reeked of sex and sweat like she had been fucking or jacking off for hours. When she peeled her jeans off her hips a meaty CLUB of cock swung outward followed by a plump meaty set of balls. Both were swollen to the point of being oversized and were leathery and veiny, like they had been overused recently.
"Gods, Jack, did you finally figure out your new horse pill dru- DAMN IT JACK YOUR COCK IS DROOLING ON MY COUCH!" you said as Jack's prick began to spit clear pre everywhere. "PUT ON A DAMN CONDOM!" you shouted as you rummaged in a nearby drawer. Grabbing one of Jack's other inventions tossed the set of several foil wrapped condoms at her. She was looking at her cock like a lover and seemed about two seconds away from grabbing her pumped up meat and going to town. "Put on one of those smart condoms you gave me. You told me they will stretch over anything so you can test them yourself." You said, worried Jack was about to bust a nut all over the couch.
"Oh hey thanks!" Jack took the condom gladly and ran a claw through the package before casually sliding it on one handed. "Yeah that's the other reason I came here. Need some more of THESE," Jack grit her teeth on the last word, flexing her floor as soon as she got the condom on and letting her cock rocket to hardness... and immediately fired a few ropes into the condom.
"Phew, thanks. It's been almost 15 minutes. Anyway yeah, the Ultra-Virilizer got finished. I figured I'd try a couple and, like, I -wanted- infinite sexual stamina and a big cock, but I maybe didn't fully think through what INFINITE sexual stamina means," Jack patted her cock affectionately and it let off another jet, the reservoir of the condom stretching up, bending inches into the air before the load fell back down into a rapidly filling tip. Jack didn't get any softer, if anything her cock just got even bigger, pulsing even wider as the veiny monster came up to her chest. It had to be over two feet, well beyond human limits in more ways than one.
You pulled out three of the little red pills into your hand and stared at them. "Uhh how many did you take?" You asked as Jack flexed her core and shot another streamer of clear pre into the slowly filling condom. Her abs were absolutely shredded and it seemed that the ticket for a six pack might be asking them to lift a two foot monster cock and basically doing a crunch every time you shot rope.
Jack seemed to have fucked her way into a killer set of abs. Her balls were also very round and looked very full. They had a healthy webbing of veins like her prick and also seemed to clench and lift a little each time she blasted pre into the condom. "Jack. Earth to Jack!" You said snapping your fingers in front of her face as she shot another gush of pre. She looked almost high, just from having mini orgasms every few seconds, it seemed to overload even her normally quick brain.
"Bwuh! Sorry," she snapped out of it midway through wondering if she should give in and just self-suck a few times again. "I took about half of them. It was either a little more or a little less, I think. Anyway if you take ALL the pills you won't die or anything. Probably would live longer, you'd just..." Jack's balls -groaned-, the leathery orbs pulsing and swelling as they overproduced hard enough to be audible. "Have some different priorities. I'm gonna take that shower now."
Jack made herself stand up, focusing long enough to peel herself off the couch and walk down the hall to the bathroom, the enormous, liquid weight of the condom swinging wildly ahead of her even as she held her cock straight to avoid smacking it into any walls. You could make your own decisions, she however needed to -actually- unload.
The rumble of Jack's balls could be heard and felt as she pushed past and headed for the bathroom and shower. Already there was a FAT bubble of clear pre hanging off her tip. You stepped aside to avoid being cock slapped as the shark walked pants-less down the hall, hips swaying in a wide legged strut pushed wider by the sheer volume between them. The door closed, barely stifling a moan as you looked back at the pills. Jack had given eleven of them as you eyed all of the shiny red tablets. A few even looked slightly sticky.
Well who hadn’t wanted a monster hog? Making your best guess, you settled on taking six of the pills and stuffing the rest back in your pocket. Cracked open a soda as a chaser, and swallowed six in a row, before sitting down on a non-sticky patch of the couch Jack hadn't touched. Wondering when they would kick in, a tingling seemed to start deep in your balls as you pulled off your pants leaving you bare assed on the couch as the effects began to kick in...
Jack sighed as she got into the hot shower, slipping off the rest of her clothes and emptying the condom down the toilet as she let the water stream over her. It was -exhausting- how good she smelled, a constant aura of lust seeping through her pores, and this wasn't her first shower today either, vibrant, shiny, tiger-striped skin stretched over a mass of muscle. Damnit, she was turning herself on just washing her body.
But then, everything turned her on now. Her two foot erection got even harder, growing out and getting dangerously red as she stopped holding back entirely, letting the -full- level of hyper-arousal her body had now picked as its default come through.
She was probably going to fill up the tub. At her level a -proper- orgasm was measured in gallons, and as thick as tar. But somehow, she didn't have it in her to mind it. She needed to actually fap.
Badly enough that she didn't realize what level her friend -thought- was her new max.
Your hand was on your cock before you knew what was happening. The wave of lust that crashed over you, flattened all resistance. GODS it felt so GOOD. You somehow felt so stupidly MALE in that moment as endorphins flooded your brain. Your balls actually twitched then CLENCHED as the drug found its way to the root of what made you a man. Both balls swelled from barely egg sized to baseball sized in a few hard jerks that had tears welling in you eyes.
The next big of the change was more pleasant as your groin muscles flexed and kegeled more blood into your cock. Your tip and shaft flared before STRETCHING forward and adding several more inches. It was almost like a workout and you were breaking out in sweat when your cock crested 12 inches. You had been only half that before and now looked down at your prick with pride. "Fuck me its perfecNGGGGHHHHH~"
Your balls CLENCHED again darkening slightly, as they swelled going through another round of growth. They ended up grapefruit sized and shockingly heavy as he hefted one of them. "Oh shit maybe six was too manHHNNGGGGGGGG~ you groaned as your whole groin flexed, pushing your prick into another round of growth. 13, 15, then 17 inches of pure meat pushed out of your increasingly crowded crotch as rolls of darker skin began to form around the base of your shaft. Looking down at your cock it was looking a LOT less human than it should be even as your hand continued to pump away. Already your balls were supercharging your mind with lust as a heavy musky smell just like Jack's began to seep from your pores. But all too soon there was another twitch starting in your balls as you yelled out to the shark. "JACK WHAT DID YOU GIVE M-UIUUUUUGGGGGGG~"
Jack had finished her shower by the time your transformation was in full swing. Her cock had relaxed enough to be -merely- the rock hard monster it was on the couch, her hair was wrapped up in a towel, her condom was back on for safety, and the tub was flooded almost to the rim with steaming white sludge that... would probably go down eventually.
"Heya, having fun with your new equip... ment..." Jack came out of the bathroom with a bright smile, ready to tease You... only to see you practically losing your mind as cockflesh writhed so thoroughly it was practically billowing with growth and change.
Change, she hadn't experienced with her own dosage, and enough to make her concerned, "Hey, it's alright, stay calm," she bent down to help you, putting a hand over your cock and feeling how... quite impossible being calm would be. Still, she ran her hands over it, seeing if she could feel any lumps or injuries.
Nope. Just a medial ring. A thick band in the center, a thicker sheath at the base. The head swelled most of all, pulsing darker and wider again and again until it stopped resembling a human's mushroom head and started resembling a horse's flare. Even the cum vein swelled, starting to protrude just a bit from the end as the transformation went further and further.
Jack sighed in relief, You weren't dying, just growing a horsecock. Well, her hands were already there, might as well enjoy feeling the last stages of growth
You were nearly comatose on the couch. Sweat covered your body, pungent with raw wild horse musk. So much stud test was currently running though your body, thinking about anything other than sating your cock was soooo hard. You had quickly reaped the other benefits of the pills like Jack had. Any scraps of fat had been burnt up to fuel the growth of the monster between your legs leaving you leaner and more muscular than before.
One hand was still on the base of your shaft above your sheath but the rest of your body was still in shock at the weight of the thing as another round of growth began. Fat black coconut sized balls churned and rumbled as they dangled over the edge of the couch while your meaty member pushed past 27 inches. "Nnnngggg BIG~" you grunted as Jack seemed to draw closer to you. Her scent seemed to make your balls rumble even harder. And when you felt her grab at your new equine accessory... "FucNNNNNNGGGGG~" you growled as her hands began to examine its new shape. The thick cum vein on the underside of your cock swelled and bulged as your spade shaped tip flared just before he spat almost a pint of instant horse nut halfway across the room. Like Jack, your whole body seemed to clench. Your new six pack popping along with all the other new muscles. The slight release of pressure seemed to help your brain a little but Jack still hadn't stopped touching the trigger as you clenched and jerked a second time, shooting more ropes of cum.
It seemed like you were blasting for entire minutes, painting your tv and making a mess out of everything, but eventually it stopped and you could breathe… inhaling a thick, masculine scent that just made you hard all over again. “Jack… the hell…” you eventually gasped out.
“Why you have a horsecock? I don’t actually know! Must be some latent horse genes… or… an extreme reaction to some of the DNA I derived the treatment from…” more than anything, Jack seemed scientifically curious as she ran her hands over your massive and still throbbing shaft, leaning in and pressing her own meat into the bottom of yours in a way you had to clamp down to avoid overreacting to.
“No… why… so horny!”
“Well you only came once! With your new upgrades you’ll need to do that at least a couple dozen times to stop feeling pent up, after that you should be good with just one big one every hour.”
You looked at your massive horsecock, violently slapping against your chest, pumping you so full of hormones you could feel the muscles growing the longer you waited. You didn’t think you were a narcissist, but you smelled so good… and you couldn’t resist, putting your hands all over it and rubbing out another one, cumming in no time with such force it hit the ceiling.
You just wanted more.
As Jack watched you sink into a haze of pleasure, drips of cum fell over you from the ceiling, and one thought occurred to her.
“Oh shit! I’m gonna have to find a third house.”
