Your stepsister and you are very close, you share a bedroom, and she opens up that she was rejected by yet another boy for being “too fat”. She exposes her belly as she gets sad over never being able to find anybody who could love her body. She then sees you getting hard, and giggles and jokes about how you can't be getting hard by his stepsister. She's surprised to hear you admit that you have a BBW fetish, and have had to hold yourself back around her to the point that you havent been able to jack off in years. She's embarrassed, but has an idea of how to solve both of your problems… She takes off her shirt and takes out your cock. She comments on how hard it is and how swollen your balls are, and gives you a titfuck with her bra on, talking dirty about her tit size and your bbw fetish. Midway through, she takes her bra off, sliding it up over her head and her breasts flop down, and she says that she's had a crush on you since you first met, and had always thought that youd make a better boyfriend than the boys she'd been chasing. After a little more dirty talk about how she's thought about you and licking your cocks head, she realized you’re close to cumming. She begs for you to let it all out for your chubby sister, and you cums all over her tits and face, turning her on further. Afterwards, she plays with the cum on her tits a little, while commenting that even if you haven’t cum in a while, this amount is ridiculous, but gets turned on that you let it all out for her BBW body. She's surprised to see you’re not done yet, and says that she wants to be your girlfriend! You say yes, and she's ecstatic. To celebrate, she proposes that they continue since you’re still ready to go. What follows is virtual cowgirl, with lots of moaning and talking about how good your dick feels while she plays with her tits. After a bit of intense pleasure, she cums and falls onto the bed. The final part of the scene is virtual missionary, She begs you to get on top and keep going and make her yours, this final scene is filled with lovey dialogue, with her confessing her love to you. You get close to cumming again, and she says that your parents will know if she gets pregnant, and you have to pull out! She desperately and sluttily begs for your cum, jerking you off as you stream an even bigger load ALL over her- and she is loving every drop of it!
