My girlfriend's younger sister has an ideal, beautiful butt... During the two days my girlfriend was away, I focused on licking and raping her huge buttocks. Kasumi Riko SSIS-502

My girlfriend's younger sister has a beautiful butt that's totally my fetish. Taking advantage of my girlfriend being away from work, I forcibly licked and violated her ass. At first, she felt disgusted, but with my tongue skills and intense thrusting, she started to enjoy it, eventually experiencing multiple orgasms with her ass trembling. Riko's vagina and my penis are really perfectly matched. I repeatedly slapped her ass with my penis in the living room, bathroom, and even my girlfriend's room. I absolutely can't tell her sister.
