MRXD-025 The most lewd and cute little sister, Kokuhana Yura, and my lovey-dovey masochistic incestuous life.

My sister got a job as a nurse and decided to move to Tokyo to live with me. She's always been attached to me… well, to be honest, her first time was with me. Three years ago she said "... the first person has to be my brother or I won't do it..." and gave me her virginity. Back then, we'd sneak away from our parents' watchful eyes and have sex all the time, transforming her into a masochist to my liking. My sister, whom I haven't seen in about two years, seems more mature somehow…
