A son invites his mother on a trip. When he suggests sharing a family bath he reserved, his mother hesitates, embarrassed about her aging body being seen. After their bath, the son finds himself lusting after her. Seeing his mother bathe is a new experience for him since he became an adult. Her breasts and buttocks seem to have sagged with age, adding to her allure. The son's eyes are naturally drawn to his mother's body, and he can't help but pounce on her.
