When I Taught Her Big Ass Sister, Who Was Not Satisfied With Her Classmate's Boyfriend, The Sexual Spot By Mutual Masturbation, She Grew Up To Be A Big Cumshot Pussy, So I Couldn't Resist To Cum Inside Her Again And Again By Adult Big Dick Piston. Yui Tenma

The first time I went to my girlfriend's house, her little sister, who was introduced to me as a JK, was super cute! With a bit of ulterior motive, I peeked into her room and saw her squirming and masturbating alone! When she noticed me peeping, she turned bright red and told me why she was masturbating. She confessed that sex with her boyfriend wasn't going well... To cheer her up, we ended up mutually masturbating, and with her first public masturbation, she came instantly, and I thrust right into her pussy!
