What's a step-mom to do when she finds out that her step-daughter is smoking while pregnant? When I realize I did the same thing, I light up a cigarette and join her. The conversation turns to how horny I got when pregnant, so I show her how I masturbated--step-by-step. A good step-mom will teach her pregnant step-daughter teaches how to rub her pussy and pinch her tits until she finally cums.
