GVG-494 - My son suddenly changed? The dangerous temptation of a darkened son

It's about a mother who has an affair with her son, who is confused by his own jealousy toward his girlfriend. But then the mother gets flustered as the son, having tasted her, starts pursuing her. While it touches on the emotional turmoil between mother and son, it lacks depth. The highlight is Mizuki-san; as a former S-class actress, her body is in its prime and absolutely exquisite. Her fuller, voluptuous figure alone is a great treat.
