Shiori Tsukada finally got her dream home, but since her stepdad helped fund the purchase, she had to move in with him. When her husband was suddenly transferred for work, Shiori found herself living alone with her stepdad and became increasingly uneasy. Her stepdad acted like a clueless, airheaded guy, making her stress build up even more. To cope, Shiori turned to masturbation as her only outlet. One day, after finishing her session, she fell asleep in a daze, completely exposed and vulnerable. Seeing her like that, her stepdad mistakenly thought she had feelings for him, lunged at her thighs, and before long... he took her completely, filling her with creampie after creampie.
