My sister is a gamer girl and a shut-in. She doesn't go to school much and stays in her room playing games all the time, but her lower body is defenseless and full of openings. As long as I don't get in the way of her game, she'll let me fuck her anytime, so today I'm going to borrow her pussy as a sex toy! I don't care if she's streaming a game! I can use her pussy as much as I want when I want to jerk off! Her sensitivity and tightness are amazing, and she's in the heat of masturbating to an erotic game, so it's the best!
