So the scene opens up from a "spying" perspective of my step-brother (you) looking into my room. I’m despondent because my boyfriend dumped me for getting too heavy. I’m trying on a button up shirt, but my boobs end up bursting the buttons wide open. Then I notice my step-brother (you) and tell you what happened and it sucks, but I like the way my body looks. Lucky for me, you like it too, which is evident from the way you’re staring at my tits. I’m happy to find someone who appreciates my body as much as I do and crawl on top of your cock. I squeeze and rub my belly, pushing it into your face, telling you to kiss it. As you do, I toss aside the burst open shirt and slide your cock inside, it feels so good I just start bouncing until my tits pop out of my bra. I slow down and take it off, pushing one of my tits into your face, telling you to suck it and how good that feels. I bounce and ride my step-brother's dick, with lots of taboo dirty talk. That’s when I reveal I stopped taking my birth control because I wanted to get pregnant with my ex. But that's okay because now I can just get impregnated by my step-brother. I ride your cock harder and faster, begging for you to cum inside your step-sister's pussy and get me pregnant. I talk about how you think my belly and tits are big now, just think how big they'll get once I’m 9 months pregnant and how my step-brother will be able to fuck me every single day. I fuck you until you blow a big hot load deep inside of my pussy, exactly where it belongs.
