My friend's sister is a bully who abuses her younger brother. While bullying her, she shows off her panties in front of me defenselessly. She knows I'm in the mood, so she purposely shows me her panties on the stairs and invites me to have sex with her. Even though the rest of the family is there, she wants to enjoy the thrill of sex. My overly erect penis goes deep into her throat and is covered in drool. In fact, my sister is a masochist, and when the family goes out, I immediately insert it, and she gets so excited that she wets herself.
