You walk in your step-Mom while she's changing into a new bra. You just love her big, round tits and it gets you hot looking at them. I notice the bulge in your pants and tell you that we should do something about it. I tell you to whip out your cock for me. I know you masturbate regularly -I found your porn next to your dirty socks under the bed. Why would you want to look at those sluts when you could jerk off to me? You're shy at first, but you decide that your step-Mom knows best, so you do as she says. I tell you to grip it tight as you look at my breasts. I also tell you to move slowly for now, I know how young men like you can get too excited and cum too fast. You imagine your cock sliding between my round tits as you grip your cock tighter. I tell you all about how I'd like to take your fat cock in my mouth and suck on it. I count to three and beg you to cum all over my face and titties. I love the feel and taste of my handsome step-son's cum on me. Once you've shot your load I tell you to clean up -wouldn't want your step-father to see this
