I got home and my parents weren't there. I go to my stepsister's room and she gets excited. She starts to move in a sexy way, she takes off her clothes and shakes her big butt. I couldn't tolerate this desire and I started to eat her breasts, then she sucked my dick and we started fucking in missionary position. Watching her fat pussy up close. Then I put her in a doggy position and when she couldn't take it anymore, I cum on her ass. This chubby girl is a whore, I love fucking her. I hope our parents never find out.
