You’re washing dishes when your stepsister Cassie says she’s going out with some guy. You’re concerned she might drink, do drugs, or get into trouble, so you warn her. A couple hours later she returns and showers with the door cracked. You peek at her sexy body and start gooning and she catches you immediately and gets pissed, slamming the door. The next morning she confronts you, but instead of staying mad, she’s super turned on. She admits she’s always extremely horny and wants sex constantly. She says you can definitely help her out whenever she’s in the mood.
