Gympregnation
by Fidget
Chapter 2, Part 3
Even with what I'd seen on the monitor from my car, nothing could have prepared me for the sheer debauchery that greeted me inside the squat, concrete building.
Beautiful gym bunnies were enthusiastically getting themselves bred all over the gym. The fit hotties were bent over workout machines in all angles and positions, naked legs spread wide, tits of all shapes and sizes out and bouncing in the open air as a kaleidoscope of throbbing, relentless cocks buried themselves deeply inside their tight, exposed pussies and ejaculated.
Even in the midst of my own insistent procreative haze, I took a second to marvel at my handiwork. The formula had worked perfectly: all of the women had been rendered submissive and receptive, their minds filled with silly thoughts of romance and destiny even as their horny bodies craved being held down and inseminated. The formula had propagated itself through the men as intended as well, supercharging their mating drives even as it hardened their cocks and filled their heavy balls with thick, potent spunk. By this point every guy in the gym was overwhelmed by a primal need to get his rocks off, to hold a fertile female down and shove his engorged cock into her cunt until the pressure of all that extra sperm finally gave way and spurted into her breedable womb.
The stink of sex and of dangerous, persuasive pheromones filled the gym. It was clear that the orgy had gone on for some time while Cherry and I made out in the car, and that the women here had had plenty of time to succumb to the influence of multiple men. I made a note that most of the females already had thick trails of cum running down their legs where they’d been inseminated by a number of different males, and as they continued to get their insatiably horny pussies pumped full of potent sperm again and again, their eyes grew progressively glassier, with the maternal hormones I had engineered programming them to become submissive breeders for every single one of their studs. And all the while there were still more men filling the air with their irresistible musk, musk that compelled the sore women to submit themselves to even more thick cocks and potent, brainwashing cum.
Luckily for the women, there had been significantly more of them in the gym than there had been men, but instead of doing something productive with their free time like trying to find a way to escape from their current predicament, the sexy breedsluts had begun taking an active role in getting their fellow horny gym bunnies impregnated while they waited. Soft hands massaged heavy testicles and cooed encouragement to the muscly objects of their current sexual obsessions, trying to encourage their virile studs to hurry up and lose control in their current fertile partners' pussies so they could take their turn.
With the thick cocktail of pheromones permeating the enclosed air of the gym I knew that it wouldn’t be long before the other men began affecting me too. The thought of allowing my brilliant scientific mind to fall under the influence of the rutting meatheads around me was viscerally offensive, but I also now shared Cherry's deep, insistent need to find Chuck, and the puzzle of what to do next stumped me for a few seconds as I stood there, continuing to breathe in the complex mixture of intoxicating funk all the while.
I knew, of course, that, more than anything else, I needed to just leave. I needed to run out the door as fast as my legs would carry me, hop in my car, and drive away before things had a chance to get even more out of hand. Unfortunately, the heavy dose of pheromones I'd unintentionally allowed myself to absorb from cute little Cherry as she'd suckled on my big, milky teats had had plenty of time to work its way through my system, and even though I was fully aware of what was happening to me, exerting that much willpower seemed all but impossible at the moment.
I could literally feel Cherry's influence affecting my personality, slowly and insidiously changing me from a brilliant, assertive, asexual scientist (except when it came to getting bred by my darling DT, of course), to an equally brilliant, but now oddly submissive human woman who was uncharacteristically susceptible to her body's base reproductive urges, and who now had a powerful desire to let someone stronger, someone manlier - someone like Chuck - tell her what to do.
Worse, in spite of my horror at the fact that there was nothing I could do to stop these effects, I was now finding myself growing increasingly excited by the whole situation. I'd learned all too well last year that mind-body dualism was decidedly bullshit: as much as I prided myself on my rational, objective brain, that brain was housed in, and ultimately inseparable from, my weak, irrational female physiology, and that weak, irrational physiology had made it clear that it loved being rendered submissive, horny, and breedable by my formula. At the moment, I was nothing more than a female in heat, no different from the basic gym thots getting themselves impregnated all around me, and on a primal, instinctual level, I couldn't help but love it.
Ultimately, as much as I knew that I should leave, it was just so much easier and more appealing for a variety of reasons to stay here, and that left only one option:
Find Chuck and then get out before my traitorous body could succumb to the other dumb meatheads' pheromones as well.
I'd already figured out what to do when I finally met Chuck. I'd quickly confess my undying love for him, give him my number, and promise to meet him later in the week once the effects of my formula had worn off for the both of us. I'd be out of the gym unscathed, and I could come back later this week, armed to the teeth with contraceptives, and let Chuck tell me exactly what to do like the submissive little slut I was.
Of course, by that point I wouldn't be a submissive little slut anymore, and so I could just stand Chuck up and be on my merry way, free to analyze my data, make millions of dollars, and track DT down so that he could breed me again. And maybe go fuck Chuck again too. Except not really.
It was a flawless plan.
I knew that my body would be growing more receptive to the other men in the gym the entire time I was with Chuck, of course, but with any luck I'd make it out before their pheromones reached critical mass inside my body, and I could just add them to the growing rotation of men to jill myself off to on the long, horny drive home.
“So which one is Chuck?” I asked Cherry, far too eagerly. And unnecessarily, because now that she was close to Chuck and her infatuation was in full force, she was already making a beeline toward him across the gym floor.
I jogged after her, following her wide hips and bouncy ass encased in her tight gym shorts. It was so odd to think that the next time I saw those sexy hips, they'd inevitably be knocked up with Chuck's baby. While I wanted to save my new BFF from that fate, I also knew that it would take entirely too long to explain, and even then with how much of Chuck's sweat she'd absorbed she probably wouldn't be willing to leave him anyway. As much as it pained me to abandon her, I knew it was the only way to save myself from the same fate. At least I knew from personal experience how much she'd enjoy it.
It didn't take long for me to discern which of the interchangeable jocks she was heading for, and so I increased my own pace, my lactating breasts bouncing painfully as I did so. My left teat was much fuller, not having benefited from Cherry's suckle session, and I felt it give way, squirting a large burst of pheromone-laden milk into my sports bra, which quickly soaked through as the nutritious fluid mingled with the sweat of my arousal and began to aerosolize. Without meaning to, I was adding to the miasma of irresistible chemical commands floating around the gym whether I wanted to or not.
In seconds I was finally standing before Chuck, and I realized that I'd been completely wrong about him being just another interchangeable jock. Unlike the other loser musclebound idiots in there, Chuck's naked figure was perfectly chiseled, like a Greek god, so incredible and powerful and manly that I simultaneously wanted him to gently hold me and kiss me and take care of me, and also to forcefully hold me down and pound me and ruin me. Which was exactly what my formula wanted me to feel, of course.
“Hi Chuck,” Cherry said shyly, getting his attention as he took a brief breather after his most recent conquest. His fully-engorged cock, still glistening with cum and fluids from his previous mate, bounced and twitched rhythmically in the open air of the gym, and neither Cherry nor I could take our eyes off it.
As soon as Chuck noticed that we were women, his eyes quickly dropped to our bodies, settling first on my large, heavy breasts, squeezed appealingly into my tight sports bra. My body wasn't as tight and perky as it had been before I'd gotten bred by DT the previous year, but in exchange my hormones had filled out my young, mid-20s body with soft, feminine mommy curves that I knew would instinctively appeal to males being bombarded by their urge to breed a fertile female.
I thrust out my chest to advertise my assets, just as I had done a year before, proud that my swollen nipples, still painfully stiff with my arousal after Cherry's nursing, would be clearly visible through the stretchy fabric. I knew it was a bad idea to show myself off like this, but I just couldn’t stop myself. I really wanted Chuck to like me, and I felt a warm, fluttery arousal filling my torso as he greedily ogled my body. I was so happy that my milk had made my titties plump up so big and full and sexy for him. I blushed at the idea, but I couldn't help but think that he was the perfect guy to plump them up even further.
Then, however, his gaze dropped, first to my own waist and hips, and then shifting over to Cherry’s wide hips and thickly muscled thighs before letting his eyes roam over the rest of her curvy body. He showed no recognition of his friend whatsoever - Cherry was now just another soft, sexy hottie that Chuck could hold down and pound his cock into until he came.
The throbbing of his large member intensified as his eyes bounced back and forth between my full breasts and Cherry's inviting hips, and I knew that his testosterone-fueled urge to spread his seed again would soon become irresistible. I needed to leave right now, because if he chose me, as submissive as I had already become, I wasn’t sure I’d be able to resist.
But I didn’t leave. I stood there beside Cherry, letting deep lungfuls of his hypnotic musk continue to convince my mind and body that it wouldn’t be so bad if he chose me. I could indulge my submissive tendencies and let Chuck’s hard muscles and relentless cock overpower and penetrate my soft, receptive femininity, just for a little while. A few quick strokes of his cock against the sensitive walls of my vagina should ease the burning arousal my formula had kindled in my body, and then I’d be good to go, free to leave before anything worse could happen.
Even better, I knew that Cherry wouldn’t be able to leave while Chuck's rod was scratching my itch, thanks to the thick cloud of musk that continued to render us compliant and breedable, and it occurred to me that I could just redirect Chuck's attention onto her once his cock had taken the edge off my arousal and desire to submit. I could go back to the car and jill myself silly to the memory of being deliciously filled with Chuck’s thick masculinity, all while Cherry took his load of dangerous baby cream in my place. It was perfect.
The tension soon became too much for Chuck, and without warning he made his choice, suddenly stepping forward and pressing his statuesque figure against Cherry, who immediately molded her soft curves against his and surrendered herself completely, just as I’d programmed her to. Chuck pushed his newest willing partner backward against a table, and I whimpered in need as my powerful Adonis demonstrated just why he deserved to mate with us by grabbing Cherry’s thick thighs and effortlessly lifting her tight ass onto the table.
Cherry stared up at him with a face full of trust and girlish infatuation as she eagerly spread her legs, but Chuck just ignored her, ripped her leggings open, and powerfully thrust himself inside. He grunted in pleasure as Cherry’s soaked slit parted for the swollen purple head of his cock, and then her tight reproductive tract was squeezing his shaft just as persuasively as the other sexy gym bunnies' had.
I couldn't help but feel a bit jealous of my redheaded friend as I watched Chuck plow her pussy, even as I realized how lucky I'd just gotten. I needed to use this opportunity to leave now while I still could, which meant that I needed to confess my love and give Chuck my number.
It felt unspeakably rude to interrupt him in the middle of sex, though, and the more I stood beside him, the less I found that I wanted to leave. His scent was so much more intense in person, similar to how DT’s had been, but with Chuck’s own spicy twist. I suddenly realized that I wasn’t just smelling Chuck’s pungent body odor: that subtle difference in musky spiciness could only mean that my nose was somehow detecting his unique pheromone signature, which meant that human females seemed to be able to meaningfully distinguish potential mates by pheromones alone.
I took a long, deep breath of Chuck’s heady scent to confirm this novel finding, holding it in my lungs so that all of its chemical signals could fully diffuse into my impressionable body. It made sense, of course, given that women generally had stronger senses of smell than men. I wanted to stay there, gathering data, breathing in Chuck's alluring musk, and letting myself revel in my powerful feminine instincts, just as I had when they had first been awakened last year by my wonderful DT.
In a purely objective sense, I knew exactly why I wanted to stay here and watch Chuck fuck Cherry, of course - my formula was working overtime in my body making me submissive and receptive. And I was submissive and receptive. I needed to submit and receive.
And so I meekly stood there beside my powerful man, inhaling his potent pheromones and watching with jealousy as he continued to thrust his big, manly cock into Cherry’s fertile pussy. It was apparent from her hairless mound that she had probably been expecting some action anyway, though I doubted that she had been expecting to get her beautiful little bald pussy knocked up with Chuck's baby in the process.
Cherry’s legs were spread wide to give her man easy access to her innermost depths, and so I had a clear, unobstructed view of the full eight inches of Chuck’s thick cock squeezing itself between her tight lips and disappearing up into her petite torso over and over again as Chuck relentlessly drove himself closer to another gene-mingling orgasm.
I dreamily ran my fingers over Chuck’s large, dangling testicles as he powerfully rammed his cock into Cherry’s cunt, ostensibly doing so so that he'd empty himself out and not have any left for me, though in reality I knew better. My formula would ensure that his balls stayed uncomfortably full of healthy, supernaturally active swimmers, and in my current breedable state that virility just made him all the more instinctively appealing to me. Ultimately, I was doing the same thing that all of the other brainwashed women were doing, serving and pleasuring the object of my pheromonal fixation so that he'd hurry up and fill Cherry with his seed and I could take my turn getting good and bred myself.
As I fondled Chuck's sensitive gamete factories, however, I noticed my attention being pulled elsewhere and took a glance around the room. I found myself admiring the other thick cocks as they continued to relentlessly fill their soft, receptive mates with their babies - hell, any one of those men would be more than capable of holding me down and giving my own pussy the procreative pounding it craved.
Oh no. It seemed that, whether I wanted to or not, my body was beginning to take a keen interest in the countless other intriguing scents permeating the gym, both masculine and feminine. Suddenly, to my horror, I wasn't finding the other jocks to be quite as dumb or meat-headed as I previously had; in fact, their glistening muscles and naked physiques were starting to look positively delicious.
Yet again this dangerous realization was enough to shock me into temporary lucidity, and I quickly withdrew my hand from where it was massaging Chuck's heavy balls between his tree trunk legs. I had been so focused on Chuck that I’d failed to notice that the men around me were also starting to get yummier and yummier. The cloud of supercharged pheromones filling the air as the men and women around me mated with abandon had finally started to take its toll, inundating me with the persistent mating signals of an entire roomful of horny, hypervirile males to the point where my body couldn't hope to resist. As much as I tried to deny it, I was slowly, inexorably being made just as receptive to the idea of letting them empty their overflowing balls into my impregnable womb as I was Chuck.
And that wasn't all - I also noticed that the sexy gym babes around the room were starting to feel like kindred spirits as their pheromones did their work on my impressionable mind as well. We were all in this together, sharing the eternal burden of being instinctively drawn to men in spite of their natural urge to cum inside us and turn our bodies into incubators.
These women were my sisters, just like Cherry was, and I found myself wanting to stay there with them, to help them however I could and maybe get a few more whiffs of the fruity scents of their sweaty bodies in the process. And if that came with the spicy musk of thick, sweaty cocks ejaculating inside their tight pussies, well, so much the better.
I once again silently screamed at myself to run, knowing that I was actively squandering the brief chance that fate had given me, but I couldn't leave yet: I still hadn't given Chuck my number.
In the meantime, my fertile body was quickly growing less worried that one of the other guys would claim me, and more worried that I wouldn’t get claimed at all. All of the bulging, naked physiques around me, glistening with their unique, captivating scents, kept me drooling from both ends as my body continued to ready itself for another bout of exciting reproductive intercourse. I couldn’t wait, and I refocused my attention on getting Chuck to cum as soon as possible.
As I did so, however, I felt a something brush against my arm, breaking my concentration on Chuck. A veritable mountain of thick, virile muscle had walked past me, searching for a fresh, unclaimed female to inseminate. My sensitive nose immediately picked out the spicy note in the musk miasma that corresponded to this new concupiscent male, and my scientific mind once again marveled at how effective the human body was at making more copies of itself.
My scientific mind clearly wasn't prepared for my body's reaction to this new potential mate, though. I'd been unknowingly marinating in his pheromones for a while now, and so what happened next was entirely predictable.
This new male's throbbing, erect cock looked practically irresistible all of a sudden as it hung there, inches from my forearm, and without even thinking about it, I reached out my hand and gently stroked it.
That was all it took. His eyes locked onto my breasts and hips, his nostrils flared, and then he grabbed me and unceremoniously pushed me facedown on the table beside Cherry.
His other hand ripped down my workout tights and underwear, leaving my puffy, soaked entrance glistening in the humid air of the gym.
Immediately I felt his swollen cockhead nestle into my labia, but before I had the opportunity to appreciate the sensation, he fully shoved himself inside me with a practiced thrust, stretching me out with the size of his artificially enhanced phallus. His large glans pressed painfully against my cervix as he bottomed out and sat there for a second, reveling in the sensation.
Despite the pain, my brainwashed, submissive body rejoiced at finally being held down and penetrated so forcefully. It was what I was designed for. I forgot about Chuck entirely - this was my man, my destiny.
As this new lover forced my head down onto the table and began pounding me from behind, I realized how wrong I had been about a few simple thrusts into my needy pussy being enough to satisfy the intense artificial lust burning in my core. It now became painfully obvious to me that my body was just telling me anything it could to get a cock into my baby box, and now that one was, I was only growing hornier and more submissive with each thrust. Now that I was so close to getting myself bred, my formula was going to make it all but impossible for me to avoid getting filled up with all of that dangerous cum churning in my lover's enormous balls.
I knew that I needed to get him to stop somehow, that I had to keep him from cumming inside me at all costs or I'd suffer the same fate I had the year before. In spite of my brilliant logical mind and immense will power, however, thanks to my formula my weak female body had become so meek, submissive and incredibly sexually receptive that I just continued to lay there, silently urging my perfect picture of masculinity to keep stretching me out with that wonderful cock, making me feel so wonderfully full as his orgasm grew nearer and nearer. It briefly occurred to me that since my gaze hadn't even made it above his massive pectorals, I didn't even know what my mystery lover looked like, but I giddily reasoned that I'd learn plenty about him from the phenotype of the product of our bodies in about nine months, and so in the end it didn't really matter.
Dazed at the intensity of the satisfying pleasure and pain coursing through my body, I gazed over at Cherry on the table next to me. Unlike me, she was face-up and staring adoringly into her lover's face, wincing slightly each time his big cock pounded into her pussy. Someone had pulled up her sports bra - whether it was Cherry or Chuck, I couldn't tell - and so I was finally treated to the sight of the seductive redhead's plump breasts, large and pale and topped with stiff little pink nipples, bouncing violently as her horny mate continued to lay pipe. Her bare legs were wrapped around his torso, locked against his chiseled ass as he plunged himself into the hole between her thighs over and over again.
My cute little friend looked so feminine and receptive and fertile in that moment - I couldn't wait to watch her become a mom in just a few short seconds.
Speaking of which, my lover apparently had a shorter fuse than Chuck did, and my eyes and Cherry's both widened as we simultaneously felt our men stiffening even further and pressing themselves as deeply inside our soft torsos as they could.
I was so turned on that I couldn't help but reach my head across and lock lips with the lovely Cherry once more as our men simultaneously groaned and began pumping huge loads of cum into our wombs, drowning our eggs in an avalanche of their relentless, unstoppable sperm.
I started to feel all sluggish as their spurts continued, like my thoughts were pushing through molasses, and my kiss with Cherry faltered as our muscles relaxed and our bodies began producing that special blend of powerful maternal hormones I'd designed to accompany insemination. My face was left lying motionless inches from Cherry's, in perfect position to watch the intelligence in my blue eyes dim in the reflection of Cherry’s equally glassy green irises. I remembered the sensation all too well from my tryst with DT the year before: we were being conditioned into breedsluts for our respective males, and as a result a bit of the bright light of our independent free will was being permanently dimmed as my formula tied us to our mates in body and mind.
The spent cocks finally withdrew themselves from our thoroughly inseminated pussies, and we continued to lay there motionless on the table, recovering and taking a moment to slowly internalize our new roles, our shared purpose as carriers and nourishers of our men’s powerful seed.
Just then, however, before Cherry and I had a chance to fully come to terms with our new realities, our overflowing vaginas were suddenly and unexpectedly stretched out again. Our men had switched places. With the refractory period shorteners I had been instructed to include, it should have been no surprise that our bulls were raring to go again so quickly, and between their priapic phalluses and their bulging seed sacks our virile mates were more than ready to mix their genes with a new partner.
I was still incredibly submissive and receptive, of course, and immediately felt my engine revving up again at the prospect of being held down and used a second time. My attraction to Chuck came back with a vengeance as his cock bottomed out deep inside my core, squeezing out enormous globs of his competitor's thick spunk in the process. Now this was the man for me. A perfect specimen of aggressive masculinity who would also surely cherish me and treat me right. Apparently I was still a bit dazed from the powerful maternal hormones wreaking havoc with my mental state as well, as I also found that I couldn't wait to give Chuck lots of babies, and he hadn't even cum in me yet.
Cherry and I held hands, united in solidarity, staring deep into each other's eyes as our tight pussies drove our mates to orgasm again, and then our hands fell apart and our eyes glazed once more with a second flood of hormones, custom-tailored to our new mates. Seconds later we were even closer, having become sister-broodmares bound to the same two sexy studs.
Even though Chuck and not-Chuck had successfully fathered children with us, their balls quickly began to fill back up with their extra-effective babymaking sauce, and the two men who now essentially controlled our lives abandoned us without a second thought to search out more pussies to mindlessly inseminate and unknowingly add to their growing harems.
I wasn't too worried though, both because I had a deep, instinctive conviction that we were destined to be together, and because I was beginning to realize that there were several other males in the room that I needed to breed with just as urgently.
I still knew that I should just leave, of course, and cut my losses now that I'd become a breedslut to these two additional perfect specimens of masculinity, but by this point I had been exposed to such a diverse cocktail of male pheromones for so long that I couldn’t consciously keep track of all the men I suddenly needed to fuck, and the simplest option for someone as passive and submissive as I had become was to just stay put and wait for them to come to me.
So, I continued to just lay there on the table beside my dear Cherry, our legs spread wide in open invitation as we oozed spent seed onto the thick mats covering the floor. As I'd known would happen, it wasn’t long before I felt another horny bull press himself against my tempting ass and thighs, ram his cock inside me, and use my body to relieve that incessant, all-encompassing urge I'd programmed into all of the men in the gym.
And, minutes later, I was a brainwashed breedslut to a third brawny beefcake (not including my beloved DT, of course).
And then a fourth.
And a fifth.
It never seemed to end. It was like I’d reached nirvana, only instead of being freed from desire I was consumed by it, my brain reinforcing the simultaneous commands to submit and to fuck fifteen slightly different ways, each tuned to the irresistible genetic signature of one of the males, all of whom were brimming with cum and overwhelmed with the desire to spread it, ensuring that they’d all get to me eventually.
It was so easy to lay back and embrace my destiny as just another slutty, knocked-up gym bunny, over and over again as my bulls ran a train on me, shoving a wide array of cocks into my sore pussy and filling me with their unique, potent, wonderful cum. And every single time they came I got to feel that glorious sensation of my mind locking down, permanently indenturing me to the life of a breedslut to yet another man. Again and again. They just kept coming, and my brainwashed body's ability to embrace sexual and reproductive slavery seemed equally limitless.
It pained me that only one of my wonderful studs could actually impregnate me, but such was the inherent inefficiency and imperfection of my human body. If I’d been in charge of the design, I’d ensure that women could be bred by as many men simultaneously as possible. Or, the eleven specific men whose cum I’d been exposed to, at least. I couldn’t care less about the others.
Still, that just ensured that I’d be all the more compelled to seek them all out again in nine months to try again. I couldn’t wait. I lay there passively, rubbing my hand along the side of my definitely impregnated belly as the latest gorgeous hunk of man-meat mindlessly had his way with me. He instinctively asserted his masculinity, at first roughly, and then ultimately gently as he massaged my tender vagina walls with the soft, rhythmic pulsing that let me know that he too was filling me with his thick baby batter. I wanted him to be the one.
I wanted them all to be the one.
Twelve.
It took another hour or so for each the jocks to mindlessly inseminate most of the submissive gym bunnies, after which their relentless need to get their rocks off inside soft, fertile pussies quickly drove them outside, through the front door that I had unwisely left unlocked in my mindless need to find Chuck, and out into a town full of both fertile, impregnable women and men waiting to realize their full potential as insatiable, cum-filled studs themselves, all of them finely-tuned breeding machines that would be helpless to resist the effects of my formula.
As mentioned, I had accounted for this possibility, and had specifically chosen a town that was geographically isolated in case anything went wrong, so that the effects would inevitably wear off before any affected person could make it far enough outside of town to affect the wider world. Even so, after my little stunt I knew that practically every woman of reproductive age within fifty miles would be thoroughly impregnated and brainwashed into breeders for a potentially enormous number of virile males.
Eventually, each of the affected men would collapse from sexual exhaustion, and would wake up back to normal, as though nothing had happened. Each of the women they inseminated in their reproductive frenzy, however, would now be irreversibly conditioned to breed herself with any of the men who had cum inside her while the formula was still active in her bloodstream.
That included me, of course, and once again, thanks to the damnable maternal hormones I'd designed into my formula, I couldn’t be happier.
I learned much later that the town had essentially become a free love commune after that. Every woman had been exposed to an effectively random subset of the town's guys, and the men quickly got used to the idea of sharing their wives, as it meant they each had a veritable herd of women desperate for them to cum inside their pussies unprotected. The birth rate skyrocketed, of course, but instead of an impossibly complex system of paternity tests and child support, the town just decided to collectively raise the children, with the perpetually impregnated women of the town sharing the work.
Back in the gym, having no desire whatsoever to seek out new men, the other soon-to-be moms and I rested for the next several hours, slowly recovering from our soreness and exhaustion as the town around us descended into sexual chaos. Luckily, the gym was far enough out of the way that no infected men stumbled upon us while we were there, giving us plenty of time to recover from being used so roughly, and allowing our exhausted bodies to lay soaking in pools of semen while our shackled minds soaked in our new infatuation with our wonderful mates. I felt a warm surge of artificial affection knowing that they were still out there, performing their masculine duty and fathering countless bastard children on the women of the small rural town.
Thanks to my formula our bodies continued to pump out our modified pheromones for the next few hours, which prevented us from leaving and slowly drew us into a cuddle-puddle of fruity-smelling, cum-coated feminine flesh. We were all still incredibly horny, of course, and so it didn't take long for our affectionate touching to become overtly sexual, starting another orgy in the wet heat of the gym.
This time, however, it was a much gentler, more egalitarian sexual experience, with plenty of satisfying orgasms to go around. Stale cum flooded out of softly licked and stimulated vaginas, but I knew the damage had already been done, and that plenty of the hundreds of millions of potent swimmers we had each been exposed to had already swarmed each of our vulnerable eggs and fertilized us.
And we couldn't be happier about it. The sentiment in the girl pile was surprisingly uplifting and optimistic after what had just happened. This was because, as sore as we were, we were all still under that permanent, artificial infatuation with each of our men, and we couldn't wait to swell and give birth to their babies.
The gym, on the other hand, was a complete wreck. More than half of the machines were knocked over, ripped men's and women's clothing lay all around the room, and the vending machines were shattered and completely empty from the jocks raiding them, desperately trying to replace the enormous amount of calories, fluids, and electrolytes they were losing from constantly cumming inside so many different women. The entire room was coated in a thick layer of semen, with large pools of it standing on the floor, and, even with all of the licking that had gone on, even more of it still dripping out of our sore, stretched, impregnated cunts.
When the formula finally began to wear off and we found ourselves capable of separating from each other again, I bid all of my sisters farewell and traded contact info with Cherry, promising to keep in touch.
Field test 2 a complete success, I noted once I was safely at home that evening, wondering which of my forceful lovers' sperm had won the race and fertilized my demure little honeypot this time. I rubbed my trim tummy expectantly, before the painful swelling in my lactating breasts reminded me that I needed to go nurse DT Junior. Formula ready for mass production.
