Incest [silent] Incest - my dad is next to me...

Aki is a second wife who lives a happy life with her husband and her son Hiroshi. However, the incident occurred last year when my husband went on a business trip for six months. With her husband absent, she is alone with her step-son... unable to endure the loneliness, Aki makes one night's mistake with her son. This one-time mistake caused the son to lose his rationality, and the two began to greet carnal desires regardless of time or place, and even after his father returned from a business trip, he began to sought out violently.
