brother/sister. POV style. "Hey bro, how was work? That's good. I just want to tell you again how much I appreciate you letting me stay with you. I was wanting to talk with you about something. I borrowed your computer today and I stumbled across some porn on it. But it wasn't just porn. It was pregnant porn. I don't think it is a coincidence that your very pregnant sister is staying with you and you have pregnant porn on your computer. Since you obviously have a pregnancy fetish I think I have a good way to show my appreciation for you letting me stay with you. *take off shirt and show off your belly to him, rub it, turn to the side to show how far it sticks out etc...* You like my pregnant belly bro? You like how far it sticks out when I turn to the side? *take off pants* Do you like seeing your pregnant sister strip for you? *take off bra* How about my big swollen pregnant tits? Mmm I know you like it. *take off panties* Why don't you take your cock out? I want to see how hard you are for me. Oh wow you are really hard. Let me take care of that for you. *blowjob using dildo* You like that bro? You like your sister's mouth on your cock? (that would go on for a bit) Mmm bro, I saw the porn you've been watching. I know what turns you on. Let me get on the bed for you. *Get on bed in doggy position* You like that? You like seeing my big pregnant belly hanging down? Mmm bro I am so wet for you. How do you want to fuck me? Missionary? Let's do it. *switch to camera view in missionary from waist up. Just simulated sex, no toy. Some eye contact would be hot* Mmm come on bro give it to me. Put your cock inside your sisters pussy. Oh yes fuck me bro. (that would go on for a bit, various dirty talk like that) Oh bro you're gonna make me cum! I am gonna cum all over your big cock! Are you close? Cum for me bro! Fill up your pregnant sisters pussy with all your cum! Oh yes I feel it! I feel your cum shooting deep inside me! Oh my god bro, that was great. I came so hard. I love you bro."
