Mamiya Shinichi, the tracer of Mamiya Hospital, and Megumi, the father’s remarriage partner, were close brothers and sisters. However, Shinichi had a problem. He was bullied by Kazu and Teru. He is required to bring her Megumi’s underwear for sale to the Brucella shop, and gradually the bully even asks to scalate and take a naked photo of Yuki Megumi. Shinichi mixes her sleeping pills with Megumi’s coffee. He takes off his sleeping clothes and takes a picture of her naked. In awe, he puts his body on his sister-in-law, but the moment the cock touches the secret part, it ends. Shinichi falls into self-loathing and slams his camera and destroys it
