Lately because of the heat my step daughter, wife and I have all been sleeping in the basement. Its a big open room that we set up as a guest room. Ever since my step daughter walked in on me stroking my cock (see other post about details) I can't stop thinking about her. Last night I was so horny I started stroking during movie time. Wife was passed out and my daughter was laying on her mattress on the floor. She had on a tight see through tanktop and I couldn't help but stare at her perfect perky tits and stroke my cock. I came all over myself and just covered it up until after the movie when I went for a shower. I want my daughter so bad.
