Her sister has a butt that hits the mark with my sexual quirks. She took advantage of her absence at work to forcefully lick her butt. At first, she was reluctant, but she began to feel my tongue techniques and intense piston movements, eventually causing her butt to quiver with continuous orgasms. Riko-chan's pussy and my cock really are a perfect match. In the living room, the bathroom, and her room, I repeatedly pounded my dick against her butt. You absolutely can't tell your sister, okay? It's just our secret...
