He is confused but she casually asks what he thinks about her new outfit. New at their college, she has no friends and acts like the two of them are best friends and can share everything. All she can talk about lately is her new boyfriend, but the last thing he expected was to see her in a sheer bra and panty set with a smile on her face. She does want to talk about her boyfriend, but what she really needs is your opinion on this new outfit. Do you think her man will like it? She wants to turn him on because lately, they haven't been fucking as often. The look on his face is a good start. She has his attention and turns around to show off the way the outfit makes her ass stick out. Yes, he will like it for sure. It is the sort of outfit that would make any man want to fuck her. She can tell that is true even of her stepbrother. He shouldn't be thinking that way about his own stepsister. How naughty. Since he likes it so far, maybe a little more? Maybe a little strip tease? OK, but only if he takes out his cock and play with it. It's OK, it will be a special secret. Such a big hard dick. It's making her wet. Making her want to fuck her fingers like she is fucking him fist. Faster, harder, that's it. Just don't tell her boyfriend that they made each other cum.
