i thought you were seduced by the unprotected milky sister, virgin boy and son who is being scolded by a super supremacist brother... don't tell me, reversal!
Chitose, who worked at an apparel shop in Tokyo, used her consecutive holidays to leave her home. However, when Yota, his younger brother who did not show up, was worried about him and asked his parents, they said that he didn't go to school because of the girl. In that case, Chitose tried to revitalize Yota by showing her Nobra milk to get her interest again, but she woke up the unusual desire for sex in Yota's sleep, and was chased around by a super-extermination younger brother who wanted to be like a monkey.
