MRXD-025 I live a loving, masochistic incestuous life with my super sexy and cute little sister, Kokoka Yura.

My younger sister got a job as a nurse and moved to Tokyo to live with me. She's always been attached to me, and I won't lie about it, but I was the one who had her first sexual experience. "I absolutely can't have my first experience with anyone other than my big brother," she said three years ago, and gave me her virginity. During that time, we'd sneak sex when our parents weren't looking, and she'd transformed into the masochistic woman I like. When I met her for the first time in about two years, she seemed somehow more mature...
