You're sitting and watching TV and your stepmommy walks in and tries to crawl over you to get on the couch. You catch a glimpse of her panties and get hard. Your stepmommy notices and starts teasing you with her panties and encourages you to stroke for her. You can tell she thinks it's just silly fun at first, but she gets more excited the longer you do it. Your stepmommy found the whole thing incredibly hot and sneaks away to masturbate, thinking about how hot it would be to fuck her stepson. Soon enough she starts teasing you without her panties on and encouraging you to cum to stepmommy's pussy. Your stepfather has no idea that this is going on and you both sneak around behind his back until you both can't stop yourself and you fuck stepmommy's pussy and fill it up with cum over and over again. It's so risky but you both are hoping you don't get caught.
