I walk into the room, my step-son's room, wearing a robe, and you can see my lingerie poking out.  I saw the way you've been looking at me, and I always like to help my step-son's friends out, giving them a guiding hand, you must have so much built up tension inside of you, it's not healthy, I've seen you staring, hiding your hard-on, now I've sent my step-son to look for something, we've got a few minutes, I'd get that cock out if I were you, and get stroking, a chance to de-stress, over me, how horny, stroking your dick in your friends room, with his step-mom teasing and stripping in front of you, until you cum on his floor. And just on time too ;)
