A niece who ran away from home. Ojisan, please punish me... Riona Minami

Riona visited her uncle's house in uniform. She is deeply interested in sex and can't concentrate on her studies because she masturbates every day. "I'm a bad boy. I have to be punished..." A childhood memory comes back. My uncle who scolded me at that time. The only one who can punish me is my uncle... And then the masochistic training began. Her immature body is tied up and her uncle's dick is thrown into her naive pussy. Pain and shame turn into pleasure and wake up to masochistic habits...
