My step mother is so attractive, fit and horny, I want to fuck her so much. It doesn't help my dad and her hardly if ever have sex, and it also doesn't help that she knows I have a big cock. She's even begun to tease me, saying things like "You'd make a woman hapy with that thing between your legs". Or like last week "I'd orgasm like a freight train sat on that monster". The thing is, she's my dads wife, yet he doesn't fuck her and hasn't for some time. I just wish I didn't find her so damn attractive, but I do.
