Hinako Matsui rapes a high school girl by dousing her jealously talented sister-in-law with sleeping pills and raping her underdeveloped pussy every night.

A sleep rape that continues to violate Imouto's immature body as he sleeps soundly. Every night, her brother's semen is poured into her non-resisting body... A body that is developed night after night and squirts with non-REM climax. A schoolgirl's vagina is filled with semen without her realizing it. An unresponsive, soft and warm surreal masturbator. While we're awake, we're good friends, brother and sister. While sleeping, sleep sex with cruel meat hole. A sleep rape in which only the sounds of sleeping breath and the screwing of a cock can be heard... “Produced and written by KM Produce Co., Ltd.”
