My Special Gift

New at their college, she has no friends and acts like the two of you are best friends. All she can talk about lately is her new boyfriend. It is driving you crazy so you cringe when you hear her knock on your door. The last thing you want is another two hour whine fest about her guy. The last thing you expected was to have her come into the room 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 your face is a good start. She has your 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 you. You shouldn't be thinking that way about your own stepsister. How naughty. Since you like it so far, maybe a little more? Maybe a little strip tease? OK, but only if you take out your 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 you're fucking your fist. Faster, harder, that's it. Just don't tell her boyfriend that you made each other cum.
