After a full day of shopping, she has decided on the perfect outfit, guaranteed to make him want to screw her silly. It is a matching set with a sheer top that leaves her perky breasts and firm nipples easily on display. As she admires herself in the mirror, Margo wishes she could get a second opinion. Knowing that her parents aren't home, she gets a wicked idea. She calls her stepbrother in to get his opinion. Calling him into her room, she watches as his eyes grow wide and his mouth hangs up. Apparently he likes what he sees and his cock seems to like it even more. It grows quickly as she just stares at her. This is off to a good start. She turns around to give him a view from the back. When she faces him again, he can see him grabbing his meat through his pants. Clearly her outfit is perfect for what she has in mind with her boyfriends, but what to do about her stepbrother and his throbbing boner. They can't do anything together, that would be wrong. Perhaps they could just touch themselves without touching each other. He doesn't object at all, pulling out his dick and stroking it while watching her spread her legs and pull off her panties. Seeing his throbbing heat poking out from his hand makes her want to fuck, but she has to settle for fingers in her pussy while she waits for her man.
