Kirishima Sakura married a man who was much older than her and had a son. Taishi, who became her stepson, couldn't help but be troubled by Sakura's defenseless appearance as she did housework every day. Taishi's gaze was fixed on Sakura's protruding nipples due to not wearing a bra, and the ample cleavage peeking out from her clothes. Unable to resist any longer, Taishi gave in to his desires and had sex with Sakura. Both of them then sank deeper into a forbidden relationship.
