There is only one thing left to do before she leaves. She has to see if her sexy step brother shares the naughty and forbidden feelings she has kept hidden for a long time. As she finishes her packing, she puts on one of her sluttiest outfits and goes into his room while he is playing video games. It takes a few moments for him to notice her but as soon as he does, the look in his eyes tells her that he likes what he sees. She tells him that she is just about ready to leave and that she will really miss him while she is away at college. Then she confesses that she has always had a crush on him and thinks about him often when she masturbates in her room. He is uncomfortable but clearly getting turned on as she bends over and shows off her long legs and tight ass. By the time she slips her top off, her nipples are stiff and she really needs some sexual relief. As her stepbrother watches, Penny shows him how she likes to pleasure herself. It feels good to let her secret out and she finds it to be a huge turn on to touch her pussy with him watching. She spreads her legs and rubs her clit, clenching her body and moaning as she climaxes for the first time with an audience. Yes, she will masturbate thinking about him while off at college, but she knows he will be home stroking his cock waiting for her to return home.
