to swell unexpectedly. to have my belly round out slowly enough to not be noticed in the hours i spend working, travelling, keeping busy… to finally have a chance to sit down and notice that all my balance has tipped forward. to sit on my bed, legs spread and back arched— arching, actually— since noticing the swell has made it faster.

my hand traces the stretching skin and i whine at the sensitivity. my skin reddens and blossoms with fresh stretch marks. my belly button pushes and pushes and pushes out until— it pops. innie to outie. the sensation makes me moan but my focus drops to my hips widening out to support the swell, ass filling out to protect the swell, thighs rubbing together to bear the new weight.

it hurts so good. i can’t tell how much more i’ve changed. i can’t see over my belly, and i can’t reach around it. i can’t touch myself and douse the heat that’s making my pussy throb.

i’m forced backwards. as my back touches my mattress, my legs tremble and i feel myself leak between my thighs, making a mess. i want to cum. i want to get even bigger. i want more and more and more.

"Oh fuck-" I groaned when I sat up my belly sloshing audibly when I shifted my weight. I felt like a huge water balloon. My gravid middle still very- not as full as it probably should be? Which was bizarre in its own right because I looked overdue with heavy twins or full term with triplets. I was heavy but it was sloshing whatever it was- amniotic fluid? That's it right? What pregnant people have in their wombs? I'd long since dismissed the idea I was anything but spontaneous and severely pregnant. My belly button popping and the dark pregnancy line were bit hints. My pecs spraying milk down my now thickening middle was what sealed that conclusion for me.

I was pregnant. With something- things? Maybe it was a slime? Slimes? It was liquid mostly or again a lot of amniotic fluid. I shifted and my heavy gut sloshed audibly once more. I'm huffing trying to stay calm because surely - surely - whatever it is must be done growing soon.

But then my still growing hangs over my knees rounding still so heavy- and thats when I barely start to feel flutters. I gasp at it because that couldn't- possibly be just the start of movement- no. My belly doesn't respond it only groans when its forced to go through another centimeter of growth. Forced to grow to keep growing whatever offspring I have in me. I laugh nervously, the fluttering still so very very light.

I wasn't a quitter! And city sized monster be damned I was going to have his baby! It would do humanity good anyway what with him rampaging during what would be mating season. So I was taking one for humanity! I'm doing this for no other reasons at all! Totally... with that in mind I actually got permission from a local monster breeding ranch to use their artifical insemination room since I was doing this for the good of humanity and all that. So they hooked me to the biggest breeder bench they had with a hole in the middle for any belly growth and get a tube pushed right against my cervix. With that they start pumping that gallon drum directly into my unsuspecting womb while I can barely keep still from anticipation.

The first pump already has me shaking against the breeder bar I'm gripping. The second happens and I can feel my womb is already full and forced to stretch further when the third pump happens. The longer it pumps kaiju cum into my hole the further my belly starts to slowly push out. Eventually hot raw pleasure shoots right up my spine and I arch, my chest sprays milk and I can only laugh when I realize I definitely just got pregnant from that last pump. And more and more thick monster spunk is only further dumped into my womb.

I'm huffing and taunt unable to tell when the groan addicting session of being bred further will happen again. I'm caught off guard everytime it happens and arching hard against the pump thats still stuffing my hole full. My belly groans and gurgles as my cum drowning womb is unable to do anything else but complain about the weight I'm forcing it to take and be bred by. My belly only grows heavier and heavier as it's spread wider by whats growing under it. My belly had long passed the expected sight of an expecting pregnancy look. I'd passed a quad carrying womb five minutes ago!

By the time the machine makes the noise that it's done pumping the cum drum. My new cum drum that's my belly is swaying softly where it's barely still suspended in the air. The bottom of my fat popped belly button almost brushing up against the floor. I looked like I'd somehow swallowed a full sized exercise ball. But even that wouldn't compare with how taunt my belly was against gravity. You could clearly see how heavy the semen stuffed into me was. The gravid weight of my middle dragging down badly wanting to rest on something.
