A man who keeps his eyes on Sae, a young wife who happily frolics with a man who seems to be a husband who is aged away, while fluttering long well-maintained black hair, and tails as if drawn to his plump body・ Sonoda. The next morning, the couple invaded the room aiming for a chance to leave the house together to see off the husband who went to work. Sae who came back alone is vainly resisted and is violated by Sonoda. Sae is sadistically violated by Sonoda, and sometimes forced to obey.
