The Experiment (Combo)
When you came home and told me about the paid research trial that you wanted to participate in, I had to admit that I was skeptical at first. Something about a breeding experiment (for science!) that tested the limits of human fertility, only resulting in inert eggs rather than actual babies… the whole thing did seem a bit farfetched. But it looked safe, you were excited, and the money was good, so who was I to discourage you?
And that’s how we started a couple of the weirdest, hottest months of our relationship to date.
It took about a week for the treatments to kick in and start to make your belly swell. It was subtle at first, your abdomen growing firm and starting to bulge out in the cutest way. I can’t tell you how often I’d catch you sneaking glances in the mirror with your shirt tugged up, turning this way and that to see it from all angles. Sometimes I’d come up behind you and wrap my arms around your middle, splaying my fingers over the bump and rubbing gently. You’d blush and mumble something under your breath, a little embarrassed but in no hurry to push me away.
It didn’t take me long to find out why.
I’d known that you had a thing for pregnancy, because you weren’t ashamed of admitting the kind of stuff you jerked off to. But we’d never really discussed getting you pregnant, or that the thought of growing new life in your womb really turned you on. Hell, maybe you hadn’t even known yourself before it’d actually happened. There was no way for you to deny it now, though, not when all it took was a little attention paid to your growing belly to make your dick hard and leave you dripping.
Needless to say, our sex life grew a lot more active.
It wasn’t all about sex, though. The research trial had to be carefully documented and your progress and symptoms regularly logged for you to receive compensation. We discovered quite quickly that this odd artificial pregnancy affected your body much like a regular pregnancy would– fatigue, morning sickness, mood swings, weird cravings, tenderness, the whole shebang. You grew pretty needy, too, though I wouldn’t tell you that to your face because then you’d probably tear up and break my heart.
Strangely enough, I didn’t mind any of it. It’s like my paternal instincts kicked in or something, demanding that I take care of you even if there wasn’t really a baby in your womb. I gladly supported you in any way I could, even on those days when your body really rebelled and you felt so shitty that you questioned whether or not you even wanted to keep going with the trial. As stressful as those days could be, being by your side left me feeling like a proud provider, a loving partner, and on a more primal level, a good mate.
So yeah. Weird but good.
Since it was an experimental pseudo-pregnancy, the whole process accelerated a lot faster than a real one would, and it only took a couple of months for your belly to reach the size of a full-term pregnancy. And boy did you get big– I don’t think that the scientists expected you to react so well to the treatments, or maybe you were just super fertile, but your womb had swollen so large that it looked like you were carrying twins. The huge, fecund mound of your belly jutted out prominently from your torso, so tight from the pressure within that even your navel had popped. Not only that, but you’d even begun to lactate, your chest growing puffy and increasingly filled with milk that tended to leak when you least expected it.
It was a real struggle for you to find clothes that covered you well without looking like a tent or constantly revealing your dripping nipples, so eventually you mostly just resigned yourself to staying home where you didn’t have to worry about such things. That and the fact that your massive belly drew all sorts of curious stares that left you uncomfortable.
It wouldn’t be long until the eggs ‘worked their way out’ anyway, though the scientists kept their description of the actual process pretty vague, probably because they weren’t sure themselves. I guess we’d find out when it happened.
Of course, my usual routines didn’t change, and I continued to work as I always did while you kept to your role as a test subject.
It was after a boring day on the job that I came home one night to find the house quiet, the living room where you usually waited for me empty of your increasingly sedentary presence. I peeked into the kitchen to find it empty too, as well as the bathroom, leaving our bedroom as the next stop.
I’ll never forget the sight that greeted me there.
You lay sprawled out on the bed without a scrap of clothing covering your gorgeous body, your face red and your bottom lip caught between your teeth as you touched yourself - one hand slathered a prescription lotion the doctors had given you over your enormous belly while the other massaged your engorged chest. You had a towel tucked over your protruding stomach to catch the milk that trickled down as the pressure within eased, and you were so focused on your tasks that you didn’t even notice me.
“Hey,” I said, chuckling when you gasped and jerked, your pregnant curves bouncing in the most attractive way.
“Hey,” you bashfully replied, your hand stilling against your swollen body. “I didn’t hear you come in.”
“It’s okay; looks like you’ve been busy.” I gestured towards you with a gentle smile. “No need to stop on my account.”
You grunted and hesitantly returned to your rubbing while I crossed the room, stripping off my shirt and slacks and tossing them to the hamper before joining you on the bed. “How are you doing, sweetheart?” Scooting closer, I slicked my hand in some of the lotion before adding my own hand to your tummy. “You’re looking as wonderful as always.”
“No, I’m not,” you grumbled, shooting me a disbelieving glare. “I’m huge.”
“You are positively massive,” I agreed with a crooked smile, my fingers splaying across the glistening surface of your gravid womb. “But in the best of ways. I never realized that you’d be so gorgeous when you were this round.”
Your already pink face grew darker, and you halfheartedly slapped at my hand. “I can’t believe I got this big. How can anybody find this attractive?”
“You do,” I reminded you, my hand briefly sliding down to cup your mound before returning to more innocent caresses. “All of those cloud drives full of pregnant porn are proof enough of that. And I do too.” I leaned close, my breath warm against your ear when I whispered, “Why else would we be fucking like bunnies almost every night?”
I felt you shudder beneath my touch at the reminder. “...Pregnancy hormones?”
“I’m sure that’s part of it, but they’re not the only reason,” I replied. You’re so warm and soft at my side, and I couldn’t keep my hands off of you any more than I could on any other day since you’d started to show. I rubbed gentle circles into the dome of your belly before sliding farther up to fondle your chest, spreading lotion over the tight skin while milk dribbled between my fingers. “I love how big you’ve gotten, to be honest. So full and absolutely bulging thanks to your packed womb. I never realized how much of a turn-on seeing you crammed full of eggs could be.”
Your only response was a faint whimper when my questing hand returned to your belly, kneading firmly against your swollen flesh. The scientists told us that the eggs were soft-shelled, and the eggs themselves were surrounded by a thin but flexible membrane housing fluids similar to normal amniotic fluid, so I couldn’t really feel any individual lumps beneath your skin, but it was still fun to ‘check’.
“Don’t push too hard,” you warned, catching my hand and holding it still.
“Why not?” I asked. “Does the pressure hurt?”
You avoided my gaze as you shook your head. “No. It’s just… it’s getting hard to keep them in, and if you push down, I might…”
Fuck. I felt a sudden rush of blood throb through my cock at the implication of your words. But I wanted to hear you say it. “You might what?”
Your throat bobbed as you swallowed heavily, shame and nerves and maybe something more momentarily stealing your ability to speak. “I– I might not be able to hold them in. They might… they might come out.”
There’s no stopping the groan that passed my lips as I kissed your cheek, the thought of those eggs slipping free of your pretty cunt only making me harder. Leaning back so we could look each other in the eye, I settled my hand just above your navel and slowly, carefully pressed down.
I gave you time to tell me to stop, if that’s what you really wanted. But you didn’t, so I didn’t.
Your lips parted in a faint moan as you clutched your thighs together, as though it would only take a little pressure to force your womb to disgorge its contents. Your eyes were wide and round, the colour high in your cheeks, and I’d bet a lot of money that if I reached between your legs right now, I’d find your pussy absolutely drenched.
“Hey, relax.” I rubbed another slow, firm circle into your abdomen, feeling the taut flesh give ever so slightly under my touch and knowing I very well could be coaxing some eggs free of your womb. “Just think of it as another part of the experiment, and let’s see what happens.”
You swallowed again, your eyes softening with trust and heat, and slowly drew your knees apart for me. So beautiful.
So I pushed down again.
“Oooaaahh…” you moaned so loudly I was almost startled. A gush of fluid splashed out onto the mattress.
“Your water broke,” I remarked, “no point in keeping them in now.”
With flushed red cheeks and deep breathing from that arousing water breaking, you whimpered, “Why did that feel so good?” The scientists did mention possible heightened sensations and extra fluids during the birth, but oh boy was this unexpected.
Immensely intrigued, I pushed on your gravid belly once again, a bit harder than the first.
“Aah!” You cried, with another small gush of fluids shooting out of your opening. “I think you just pushed one through my cervix.”
I slid a hand into your wet vagina and found my way upwards. Your breathing hastened as I reached just below the top of your birth canal. There, I felt a small ball of liquid held in a thin film with tiny lines indenting its surface. It was the first of many eggs to come.
I retracted my hand, accidentally hitting your G-spot on the way out. You jolted with pleasure, and yet more juices dripped out of your opening.
“Rub me off, please!” You begged, as a contraction seemed to take place, your belly tensed and squeezed in visibly.
In your vulnerable state, your gravid beauty was amplified a hundredfold. I waited no time to oblige, my juice-soaked fingers sensually circled your clitoris.
“Mmmnnn, mmmmnnn” the sounds you made were so unbearably arousing. Each contraction pushed the egg further down your birth canal.
As the egg neared the opening, your gaping pussy opened to a cute teardrop, and then a nice fat oval shape. Your moans grew ever louder, a sweet-sounding cry accompanied every contraction. These contractions don’t seem to be painful at all, perhaps your body knows full-strength contractions for human babies would squash the soft and delicate eggs.
Soon after, the egg came to a crown. After some ten minutes of pleasuring from me and the unexpected aphrodisiac effects of your birth, the sounds you made were as incomprehensible as they sounded ecstatic. With a loud scream of absolute pleasure, the egg plopped out to an arm’s length followed by more fluids drizzling out. There was a small blue “core” near the center of the spherical egg, surrounded by clear transparent liquid, and all wrapped around a thin membrane with tiny millimeter-sized twisting lines like the mazes on the surface of coral. The egg was about the size of a fist.
“It’s born,” I remarked, carefully picking up the egg and bringing it to beside your head.
“The first of its siblings,” you replied before you were startled by a contraction that seized your belly. Another egg was on its way out.
A stream of liquid suddenly dripped from your chest. Milk.
If this were a human pregnancy, it would be vital not to waste much of this baby food, but given we’re not having human babies…
“I hope you don’t mind if I help myself…” I whispered into your ear as I caressed your breasts.
“Aaahh…mmmnnn” You whimpered as the egg travels down your birth canal, and I fondled your breast.
Feeling naughty, I aimed your nipple at my open mouth and squeezed. You squealed in pleasure, as did my insides when I heard your cries as sweet as your candied milk.
I could hold back no more, and put my mouth on your supple breasts with its puffy nipple, and suckled.
“Oaahh!” You yelped in pleasure, and another egg plopped out of your gaping vagina.
As I continued to suckle your honeyed breast milk, I played with your other breast. In your pleasured whimpers, I brought the nipple to your mouth and you suckled just as I did, perhaps even more sensually than I am with wet slurping sounds emanating from your mouth.
In this haze of pleasure, another egg was born without us noticing, then another!
Once your breast was sucked dry, I finally noticed the eggs between your legs and was instantly annoyed. I was supposed to see each and every birth, not have it be skimped over when we were having fun elsewhere!
As another contraction squeezed your belly, I helped out and pushed on your belly like before. The egg rushed down much quicker than the others, and in no time it was at your opening, only to meet an immovable wall of my hand…
"Please, I can't--"
"Aw, of course you can," I purred patronizingly, relishing in your whimpers as my hand came to rest where the egg was making your lips bulge out. "Besides, doesn't it feel good?"
Your cheeks flushed scarlet, but instead of protesting like I expected, what came out was a low, shaky moan. Slowly but surely, I carefully pushed the egg back up inside you, past my lips and threatening to pass back up into your cervix. The only thing stopping it was the rest of the clutch that was trying to descend, but either way, I’ve undone almost all of your progress.
You let out a frustrated sob, groaning softly as both of us felt another contraction coming on. This time I kept your hand over your cunt, pressing firmly as I gazed intensely at you and vice versa.
"Ah, ah, ah, not yet...just a little longer, I want to see how long you can hold out for me, then I'll let you push." I chided, running a finger through your drenched folds, ready to intercept if any of the eggs started to move again.
Not having much choice you simply nodded, bracing yourself and doing everything you could to resist pushing. I licked my lips devilishly, watching as you struggled, reducing you to a sweaty, whining mess.
"Oh, you poor thing, I've been too rough on you, haven't I?" Chuckling darkly I moved closer, draping myself possessively over you. One hand splayed over your belly, the other still stroking and teasing your pussy, and when I felt the telltale tensing of your body under my hands I leaned in close, whispering directly in your ear:
"Push."
Your eyes snapped open, and you acted quickly before I could take back what I just said. Grasping at the sheets under you, you grit your teeth and bore down as hard as you could, almost wailing from the effort. I was taken aback as your body seemed to act in overdrive in order to make up for all the progress I stole from you, and you panted harshly as you birthed several of the eggs one after the other. After which they were placed near their siblings close by.
Your belly was much more deflated now. Feeling around, there seemed to be only one egg left in your womb. Taking advantage of your temporary drowsiness from birthing so many eggs in quick succession, I slid my member, already hard since an hour ago, straight into your pussy. Your soaked walls allowed instant entry for my entire cock.
Your shocked face was absolutely priceless.
You tried to protest but when I started thrusting back and forth, you could do nothing be indulge in the immense pleasure.
“Babe, this is the last egg, you know I’ve wanted to do this,” I uttered.
“Oh, fuck y—,” you sneered but were briefly interrupted by a contraction.
As the contractions continued, the egg dropped further into your birth canal, and eventually met the tip of my cock.
I had thrust comparatively slowly in fear of hurting the egg. This already sensual kind of sex coupled with your orgasmic birth has done nothing but spur on our lust. Wanting nothing but pleasure right now, I thrust deep into you and pushed the egg back through the cervix.
You gasped in intense sensation as the egg returned to its womb and I started to thrust faster given the cervix was a barrier for my ramming dick.
I was getting close to releasing and so were you, both of our grunts and moans grew louder than ever before. To make this an unforgettable experience, I guided your hands to your breasts, then moved down to squeeze hard on both of your ass cheeks as you did so to your breasts. You jolted in pleasure, and I started to feel rhythmic squeezes on my dick. I removed one of my hands from your pulp ass and instead rubbed your clit with it. You screamed with an avalanche of pleasure.
My naughtiness seemed to catch on as you seemed to crave even more despite the intensity of the ongoing pleasure.
You brought one of your breasts to my mouth and commanded, “Suck it!” I gladly obliged. I sucked as best as I can, making it as close to a vacuum as I can manage just as you did yourself. Your vaginal squeezes were so frequent now, even matching my thrusting rhythm. My dick was throbbing hard, each thrust, each squeeze, and each suck bringing us closer to the climax to end all climaxes.
In a flash of white, both of us spewed out all of our juices along with our most primal cries of infinite pleasure. Your gaping pussy was filled to the brim with my white, hot cum, and our mouths were spewed with fresh milk. It was heavenly.
After a few minutes of post-orgasmic haze. A contraction squeezed on your womb. I removed my cock from your vagina and allowed you to birth your final egg unimpeded, after which, we put all of the eggs in a large pot of water and left them to grow on their own as advised by the scientists.
At long last, we cuddled together in intense love until we both fell asleep.
This, was quite the experiment.

Anon gym says they’ve had this in the works for a bit, and when writing it, they weren’t aware that @hush-writes-preg has written a series on this. I think it’s an interesting continuation compared to hush’s part 2, with the partner plugging the carrier. The “Push” part feels a bit rushed though.
