Katsu has always peeked at his mother Natsuko bathing whenever his father is away on business. He's obsessed with her mature body, but one day, Natsuko catches him and invites him into the bath. Overwhelmed by shame and arousal, Katsu is led into a forbidden encounter as his mother whispers, 'Just this once...'




















This is a staple series for this studio, but while I can forgive the sagging breasts due to her age, that 'prostitute-style' pubic hair trim is a major turn-off. Maybe that's just Kayama-san's usual line of work, but it kills the mood. On top of that, the dialogue and scenarios feel way too condescending. Her loose body isn't exactly something a son would want to peek at. The reviews aren't great, but I personally didn't mind the scenes where she wears hair rollers. Still, I wish they'd cast a younger, more modern actress next time; the contrast might actually be interesting.
That body is just too erotic. It looks like a body made for sex. It makes me want to rip her underwear off without thinking.
*Even big actresses can't beat their age. Those magnificent breasts are sagging. The story is about my son who was peeping at me while taking a bath. The content is that they are dragged into the bathroom and tangled with each other. I also give my son a titty fuck and a buttjob when he comes to watch me take a bath.
The shape, size, and weight are flawless. It's a dream for ass lovers. The bathroom scene was great, too. That said, I wish the male actor had been younger. As others have mentioned, the 'son-only' dynamic is good, but I would've liked more scenes of them going at it repeatedly. Also, it would've been perfect if there was a raw shot during the doggy-style scene.
As the title suggests, this work focuses on scenes in the bathroom. While there are plenty of titles featuring oral sex in the bath, there are surprisingly few that actually show full intercourse, so this really hit the spot for me since I'm a fan of bathroom scenes. With her naturally suggestive expressions, fair skin, and voluptuous, curvy figure, Kayama-san is the perfect actress for a film centered on bathroom scenes. I honestly think the story would have been perfectly fine with just the son, so I'm not sure why they felt the need to include the son's friend in the mix.
