Every time I've put on my lingerie lately it's had sticky cum on it. I know its my stepson jerking off and leaving his cum for me to find. I finally have to confront him about it, but that just gets him all excited seeing me in my see thru underwear trying to act like I don't see his hard on. Maybe the best thing to do is just let him jerk off with me from now on. I play with my pussy as he watches and to my surprise he comes to me and pops his load on my tits and bra. I have to confess I even sneaked a little taste of his cock in the process....Hope his dad doesn't find out!
