Steamy incest mother and child bathing copulation

Wataru has recently become concerned about his mother's body, and has gotten into the habit of peeking at Ryoko while she is taking a bath. Ryoko was aware of her son's behavior, but pretended not to know. One day, when Ryoko saw Wataru peeking into the bathroom as usual, she suddenly called out to him, saying, ``Come in, I'll wash you.'' Although Wataru looked surprised for a moment, he obediently entered the bathroom. Ryoko, feeling love for her son, gently guides and accepts Wataru, whose penis is erect.
