meant to post this yesterday! hope this is good.

lactation, drugs/aphrodisiacs, breeding, held for experimental testing. pregnancy mentioned briefly but doesn't actually happen.

damien hadn't known what to expect upon signing up for a paid experimental trail. he needed the money, badly, and pretty much jumped on the opportunity when it was presented to him. the group running the trial sent him plenty of information packets about what he'd be expected to do, but he, admittedly, didn't really read them too far. two pages in and he just started skirting the page, getting the main details and forgoing everything else. he knew that it was a fertility test, so he figured it couldn't be too hard.

now he wishes he had read the fine print.

"vital signs are normal, besides a slightly elevated heart rate. test is a go; authorizing."

a voice speaks through a speaker, the only connection damien has to the area outside of the room he's been placed in. the room is sterile and white, with a viewing window on one wall that can't be looked out of. in the middle is a bed that damien is currently strapped onto. the bed is lightly elevated so that he's reclining instead of lying. his ankles and wrists are strapped down, and his tits, fat and engorged, are each strapped into a pumping device. his full tits are being milked, pump after pump of the sweet white liquid entering the clear ten gallon drum next to the bed.

damien couldn't move if he had hoped to. one of the things the trial runners have done is kept him on a steady injection schedule of experimental drugs. things to make him complacent, things to make him horny, and things to make his body produce milk at a high rate. so far, the experiments haven't gotten him pregnant yet— something they hope to change.

when the hidden door on one of the walls opens, damien's clouded eyes focus in on it, whimpering as he sees a strange man staring back at him. another trial participant, the man is fully naked as well, with a large, throbbing erection. he wastes no time entering the room and approaching damien, after which the speaker on the wall fizzles with a quick, "proceed."

the man settles between damien's legs, holds his thigh with one hand while the other rubs his cock over damien's cunt. damien is soaking wet, his juice leaving a wet spot on the mattress beneath him. when that cock touches him, his hips twitch upwards, and his mouth opens in a desperate moan. when this whole thing started, damien was reluctant, scared. with the drugs running through his veins now, he can barely gather his thoughts enough to care. all he knows is he's hot, unbearably so, and the only thing that gives him relief is a cock deep in his cunt.

the other participant teases him for only a little long, rubbing his cock over the whole of damien's pussy before pressing the tip to his whole. when the first few inches slip in, damien arches his back, whining. the other man groans as well, undoubtedly also influenced by a similar aphrodisiac. the man only has the patience to slip in halfway before he starts to thrust, pressing in more and more of his huge cock with each desperate stroke.

it feels wonderful. damien is beside himself, twitching his hips up to meet the man's every move. his cunt is fluttering around the man's cock, clenching and unclenching in a way that spurs the man into going harder, faster. the pump keeps working away in the meanwhile, and the relief of having his large tits milked in combination with the rough sex has him coming in moments.

there's no stopping the man, though. with a bruising grip on damien's waist, he starts to fuck faster, harder, panting openly as he enjoys damien's tight little body. he thrusts in deep, hitting damien's cervix over and over again. the pain-pleasure of it has damien shaking, his hips still moving towards those thrusts. within just moments, the man manages to get deeper, pressing into damien's womb once his cervix gives to the rough treatment. once inside the deepest, tightest part of damien, the man starts to come, copious amounts of it filling damien up.

being filled is so good. damien is panting, his wrists fighting against their bonds as the pleasure overwhelms him. he gives out loud, sensual moans, nearly crying as he comes again. it feels so good. it doesn't stop, though. the man is no less hard after coming, and continues to keep his hips moving, fucking damien without pause. cum is leaking out around his cock, making damien's cunt wet and sticky as he pounds into it.

the speaker crackles, but neither of them quite hear what it says. the two are stuck in a loop, focused only on receiving pleasure from each other. they don't know how long it goes on for. the man fucks and fucks and fucks, scratching his fingernails over damien's skin as he pushes in as deep as he can go. damien can only take it, trying to match his movements as best he can. it isn't until the man blows his fourth load into damien's cunt, spurring damien into his own orgasm, that things start to wind down.

damien is beside himself in pleasure. he's overstimulated, trembling deeply as that cock settles deep inside of him. neither of them are moving anymore, simply panting. the hidden door opens again, and a man in a white lab coat approaches their bed. he places a hand on the other man's shoulder, which makes him twitch.

"good work, 032 and 015."

the man is removed from damien— as his cock slides limply out of damien, thick ribbons of cum follow it. the scientist doesn't seem too concerned about it, most likely because of how stuffed damien's womb already is, a visible bump having formed on damien's otherwise flat stomach. the other participant is led out of the room, leaving damien to lie there, shaking and panting. the pumps on his tits are still working, and as they pull out more milk, damien finds himself overwhelmed and whining desperately. another scientist comes to check him out, but not before his stimulated tits lead him to come once more.

"you are doing well," the scientist says as he adjust damien's bindings. "your milk output is incredible. we just might have to keep you after all."

damien doesn't understand. his mind is like mush, and no words come to him. the scientist simply smiles at him as he cleans damien up and preps him for the next experiment.
