Your stepmother is in the kitchen doing dishes when you not only notice how big her ass has gotten from her pregnancy, but she also has a whole in her see through white leggings and you can’t help but stare. Eventually you get caught with a big boner and your stepmother doesn’t seem phased at all, she even invites you to rub your boner against her ass while she finishes the dishes. Aroused by feeling your hard on pressed against her she offers you a blow job. After sucking your cock and pulling her leggings down a bit she invites you to her room, undresses completely, encourages you to stroke for her and then asks you to fuck her tight little ass and fill it full of cum.
