Doctor's came out with a new drug that would decrease the duration of pregnancy and needed volunteers. You were warned that the growth would be rapid and signed the waiver, only as you swallowed the pill you remembered that you family had a history of multiples during pregnancy. Twins were common but all of your sisters had triplets the last time. The pleasure was sudden and intense, as they place the ultrasound wand on you panic erupts in the room. Catching a glimpse of the screen you count 4 rapidly growing babies.
"um i forgot to mention– ohhhh," you try to explain as a growth spurt hits, your belly pushing through the cloth gown they gave you for the trial. your hands fly to your stomach, in awe of the rapid transformation as a wave of pleasure and pain shoots through you. your boobs ache as they grow alongside your expanding belly, straining against the bra you left on. your fingers shake as you work to unclip the tight fabric, and you remove your bra just in time for your boobs to plump up another cup size.
"my family has a history of multiples," you finally manage to get out, laying back on the hospital bed trying to catch your breath.
"i'll say," one of the nurses mutters, saying something about running to get more medicines for the IV drip attached to your arm, injecting you with nutrients as well as the rapid growth serum.
you moan as your belly expands, your hips cutting into the lining of your panties. everything is growing rapidly, from your ass to your tits to your ballooning belly.
"feeling okay?" a doctor asks, holding a clipboard.
you nod as you feel a gush of wetness flow south. you've never felt so horny in your life.
"the serum also has an aphrodisiac element to curb the pain of the rapid growth. we just increased your formula considering you're growing multiples, so you might start feeling those side effects," the doctor says. "pushing into the second trimester now."
only the second trimester? you look eight months pregnant with a single baby currently. the heft of your belly is weighing you down, and you struggle to try and sit up, letting the continuously expanding bulge rest between your stretched out legs.
you huff from the effort, resting your hands on your back to stretch. as you arch your back, you look down, noticing just how large your midsection has become.
"you'll start to feel some movement in a moment," a nurse says, and you watch in morbid fascination as your belly begins contorting, the offspring inside you beginning to jostle for room as they grow.
"oh god," you touch each little movement with your hands, feeling another rush of pleasure hit you in your core. you try to reach down, but between your expansive belly and fat thighs you can't make contact with your clit or anything for that matter. "ugh, i'm so full"
"nearly at the third trimester, this is when the babies grow the most, and they look like they are measuring in a higher percentile than most," says a doctor.
god. you're so full of so many babies and they are all so large. leave it up to you to be the biggest trial of this experiment.
the room is a buzz with anticipation as you groan through another growth spurt, getting impossibly bigger.
your boobs rest on your shelf of a belly, pushed up into your face. they ache like hell and you hear a nurse mention lactation starting soon.
the movement is insane. you feel so full of babies, so transformed within just the last thirty minutes. the children in your womb jostle against each over and your belly is so big it seems to move on its own, leaving you moaning as you move with it.
you can't reach your arms around yourself anymore but you can feel your belly button straining against the occupants within you.
"alright that's time," a doctor informs you, "you should be full term. now we just have to wait for your water to break."
"how long until that?" as much as you're uncomfortable and fuller than ever, you're also immensely enjoying the feeling of creating life and letting it grow within you.
"hmm anywhere between two hours and two weeks. part of the trial."
"what?!" you were fine with this when it was only a brief pregnancy but the idea that you might be stuck this big for so long makes you realize just how immobile you've become. you probably can't even walk at the moment. your belly towers in front of you, full of movement and life. your boobs have finally started to leak. you couldn't even lean back without being crushed by your own body if you wanted to.
"it's all part of the trial! will be interesting to see how long it takes with multiples. i'll be back."
and with that, the doctors move out of the room, leaving you and your massive brood to wait it out.
