Her sister was a famous gravure idol! She's the complete opposite of her, with a crazy figure and lewd aura! And she's super lewd! Hey! Big sister! What are you doing?! She shows off her perverted, busty swimsuit and provokes me, a shy girl! She doesn't care that my girlfriend is right next to me, she seduces me and acts like a slut! While my girlfriend is sleeping, she straddles my dick and sways her hips with a lewd look on her face, cumming like crazy! This girl... might be a dangerous person... The whole video is from a subjective point of view! Binaural recording!
