He hears an odd sound. It was coming from his sisters room! He follows the sound and peeks in through the door to find her cumming all over her toy. After watching for a few moments, he speaks up about her being loud. She tries not-so-hard to cover herself and claims that she had no idea there was someone home. After inviting him into her room, she hits on him. She confesses that her best orgasms happen when she thinks of him.
