I watched the mother-son hot spring drama starring Kato Ayano, where the actresses shone brightly, but the casting of the male actor left room for improvement.

Kato Ayano boasts a pure face and excellent figure, with ample breast volume, and her mature, seductive acting shines throughout. The initial kiss scene at the inn, with its moist, emotional lip-lock, and the transition from a yukata to red and black lingerie are visually stunning. In the bath scene, from breast fondling and drooling nipple attacks to handjobs while sucking breasts and penetration, the subtle shaking of breasts in the cowgirl position highlights the eroticism, and from fellatio in black lace lingerie in the changing room to chest ejaculation, Kato's sexiness is fully displayed.

In terms of story, the setup of a mother troubled by a sexless marriage deepening her relationship with her college son at a hot spring feels realistic, and Kato's careful portrayal of emotional changes showcases her skills as a top mature actress. The mother-led flow typical of mother-son themes is well-received, offering charm that makes viewers want to watch repeatedly.

However, the male actor playing the son faced concentrated criticism like 'pathetic,' 'too old,' and 'should remove the glasses.' Some viewers found the slow-paced intimate scenes not to their taste, calling for a quicker tempo. When the same male actor is involved throughout, the ease of emotional immersion affects the work's quality, so future improvements are hoped for.

Overall, Kato Ayano's beauty and acting make it well worth watching, but the male actor's lack of skill seems to underutilize the film's potential. The hot spring incest scenario is praised, but many fans wish for a recast and another attempt.
