Kanon, who had been living with just her father, now has to deal with her father's new wife and stepbrother moving in. She was in a rebellious phase and found the situation intolerable, feeling irritated by their presence every day. Driven by her age and hormones, she was caught masturbating in her room by her stepbrother, who then blackmailed her. Kanon had no choice but to keep quiet and obey him. She was forced to take his bare penis, and despite the humiliation, the intense pleasure pushed her over the edge into orgasm. For the next three days, she was continuously penetrated and filled with semen.
