A son invites his mother on a trip and takes her to a family bath they had reserved. When the son asks if she would like to join him in the bath, the mother feels embarrassed because he might see her aged body. After getting out of the bath, the mother becomes aroused by her son's lustful gaze upon seeing her naked for the first time since becoming an adult. Her breasts and buttocks were sagging, making them appear erotic. The son's eyes naturally wander towards her body, leading him to attack her instinctively. *Note that the recording contents may vary depending on the distribution method.
