[Forbidden sex between wet skin] Megumi is a newly-wed wife who is having trouble building a relationship with her husband's stepchild. One day, her husband goes on a business trip and she is left alone with her stepson for the first time. Feeling sexually frustrated, she indulges in shower masturbation in the bathroom when her stepson peeks in... She is aroused by the sight of his rock hard cock, and seduces him with a close-up breast wash, a titty fuck, and a sweaty creampie, turning her into a lustful beast who demands ejaculation over and over again.
