My younger sister, whose sexual desires are rampant when her parents are away, ravages me, her older brother, with her huge ass and pounding on me in a riding position. (MIDV-124)

While their parents were away, my younger sister, Hua, suddenly became a lewd woman and played with me. "Mom and Dad aren't home today..." Knowing how pleasurable sex is, even after I ejaculated, she still straddled me, using her large, white buttocks to bounce and thrust. "Does brother like my ass?" Even knowing it was wrong, I couldn't resist her bouncy, tender buttocks and her seductive whispers. Whispers in my ear about riding positions, swimming in a school swimsuit, seductive buttock penetration, and lewd tongue-licking sex. My sister has become so wanton without me even realizing it... I won't be able to masturbate anymore...
