Mio Kanai, a teen schoolgirl with fat boobs, sneaks back home to give her stepdad a dirty bj while he sees TV in his study. She frees his ginormous manmeat and commences deep-throating it like... a pro, using all of her skills learned from observing Japanese xxx flicks online. As she deep-throats him, she imagines herself being banged by a muscular dude with a massive spear who treats her like a real slut. Her fantasy gets even hotter when she thinks about how her mummy neighbor might catch them in the action and join in for some three way action. With her tasty cooch still dribbling moist from her last orgasm, she plays with various romp fucktoys until she eventually jizzes again, squealing like a porno star.
