Step Mommy's Fertility Problem

Step mommy is trying to get pregnant, but there's a problem. technically, it's not her problem - it's your step dad's! he's infertile! the doctor says his sperm is just too old to be any good. you, on the other hand, have fresh, young sperm - just what the doctor ordered! won't you be a good boy and help your step mommy out? she'll even lick your cock first to get you nice and hard, then ride you while talking about how her body will change when she's pregnant, before laying on her back so you can squirt your cummies into her.
