Monkeyman-

For Pete's sake don't get caught around your stepmom with a hard-on, or worse yet masturbating! Unless your dad and stepmom are the wildest swingers I can imagine, you would be much better off by clamping down on your sexual urges in relationship to her. If your profile is accurate, you're old enough to manage that if you want to, after all, most normal adult males would end up in jail in our society if we tried to have sex with everyone we were turned on by.
