CW- mpreg, sex, language, Step-Son X Step-Dad storyline

I always fancied my step-dad since i met him i thought he was hot, hes a classic himbo, hes tall, muscly, blonde and stupid as can be.

I never knew if he was purposefully flirting with me of was just too stupid to understand it was wrong, but it being wrong made me so horny, id often wank off after he’d compare our hand sizes, snuggle up to me or even bend over to empty the dishwasher, anything and everything he did turned me on so hard! he always wore clothes that left nothing to the imagination, short-shorts, crop-tops or no tops! My actual dad loved this about him and it made me so jealous seeing them cuddle and kiss and then one day… my dad went on a business trip. it was now or never.

i came downstairs in my dressing-gown and boxers showing off my abs and mediocre pecs i walked into the living room to my step-dad half asleep on the couch only in his briefs and white running socks, sweating and scratching his perfect body when he saw me he woke up a little and pushed a finger into his underwear suggestively “oh… hey man” he said in a gruff half awake voice “h-hey” i stammered taken aback by how horny he already seemed my cock visibly swelled in my already tight boxers. he glanced down to it quickly and blushed “come here pal i have something to show you” he said gesturing for me to walk over- i follow his orders and sit next to him, he places his hand on the back of my head and pulls me in for a deep long kiss. i rest my hand on his groin and feel his cock twitch and harden through his pants i then slowly kiss his neck, then his chest, then his abs until his beautiful totem-pole of a cock is in-front of my face. i confidently slip it all into my throat in one go and he lets out a little moan.

i suck him off for what feels like an hour before he pulls me up by my armpits and spins me around, he lifts my dressing gown up and squeezes my ass before bending me over the couch as he teases my underwear down making my cock twitch due to the prolonged friction, he then rubs the head of his penis along the outside of my un-used hole while i beg for his cock i then moan loudly as he slides it all in at once. he grabs the hair on the back of my head and holds my cock in the other one of his massive veiny hands his expert technique instantly turns me into a worthless hole only purpose is to please him, after a few hours of fucking and cumming we fall asleep on the couch naked together.

after a few more days of constant fucking, sucking and cumming my real dad comes home and we have to start being discrete, doing it in one of our cars or while hes away or even just quietly under the kitchen table, the closer he is, the hotter we find it.

after months of this i notice a small ball in the centre of my stomach while getting dressed i think nothing of it and carry on and on until its too obvious to hide under baggy clothes, i tell people im just bulking cause i want to build mass, i wanted to believe it but me and my step dad knew it was more.

his cum must be super-human i quickly became the biggest pregnant person id ever seen i stuck to my story but less and less people believed it that was when my dad confronted me “hey buddy!” he said putting his head around my door into my room as i lay weighted down by my planet-belly, “ive noticed that your clearly pregnant” i try to sit up and defend myself but it takes me far to long to even start bending my mid-section “you dont need to deny it i know what it looks like-you where one hell of a baby! anyway i was just wondering who the daddy was and if hes in the picture” i knew he was asking because my other dad was never in the picture “well erm he kind of is” i finally admit rubbing my tight taught skin “its m-my step dad” i say defeated. “no fucking way!” my dad says more surprised than angry he finally steps fully in my room without a shirt on revealing his own pretty-large pregnant belly…

Brain rotting to this mpreg thing,

Twink is possibly pregnant, so he goes to the doc to confirm. He flirts with him the whole time, getting hot and bothered on the table, and eventually the doc gives in and fucks him outright, then and there. If he wasn't pregnant before, he is now.

When he shows up next, he acts naive and unaware. As though he has no idea who the doc is or what they did together. The doc seems surprised at first, until the twink exclaims that he gets super horny sometimes and forgets everything that happens afterwards once he is.

"I'm just such a forgetful bunny," he exclaims, "it's a wonder how I've only been knocked up with one!"

Soon enough, the doc figures out his secret. He learns what shuts off his brain, and what makes him a horny, forgetful mess. He uses it to his advantage, ravishing him in the doctors office each time he shows up, and putting another baby in that fertile womb of his. Every time he comes back for another scheduled "check-up", he's a little rounder, full of his doctor's growing spawn.

pretty rude that there isn't a heavily pregnant boy writhing and crying prettily from unbearably painful contractions on my floor rn

I want to be round and swollen, skin stretching and hips widening. I want to feel your baby kicking inside my belly, gentle at first and then stronger and stronger. I want you to run your hands over my pregnant bulge and feel the life you put in me move.

Getting some good belly rubs 😏🎈
