Cory is obsessed with Halloween. She loves dressing up every year and going to parties, but the only problem is that her husband doesn’t let her wear any slutty outfits because he is a very jealous guy. Yet this year is different as Cory’s husband is out of town, and she can be as slutty as she wants. The only obstacle to Cory’s dream of dressing up slutty, is her stepson Anthony, who catches her wearing those little costumes and threatens her of accusing her with her husband. Cory is aware that her stepson is a virgin nerd and can’t really resist his stepmom’s slutty costumes, so she makes a deal with him: she will fulfill his sexual fantasies and he won’t tell on her.
