She starts to strip and tease you by finally lifting up her dress so you can see the ass you have been dreaming about. She says that you should take out your dick and stroke it for her. She slips out of her dress and begins to remove her bra as well. She says that since she’s your step-mom, you should call her step-mommy. She laughs saying that she knows it’s fucked up, but it kind of makes this even hotter. Your dick agrees. She strips down to completely nude and shakes her fat ass right in your face. She bends over the counter and rubs her pussy while telling you to stroke harder. You blow a massive load as she cums hard. She says that you have to keep this a secret, but maybe you guys can fool around again in the future.
