So your girlfriend has told you that she has to get to work, so you and your "boyfriend" (you know he is a perv at best) are left to spend the night having some quality time together like you used to when you first started dating. You think it might be fun because both of you look sexy and tight in your little girl dresses but then as the night goes on you notice something missing. Your girlfriend is getting fatter but she won't be able to go down on you because her new big boobs keep squeezing into her bra. Before you know what's happening you find yourself in bed with a horny stepmother who is about to teach your girlfriend a lesson she will never forget..
