After watching the 7th installment of this series, I was captivated by the chain-reaction plot where a young wife working at a cafe has her weakness exploited, dragging in colleagues and mom-friend customers. Sakino Mizuki's voluptuous breasts and butt, along with her expressions during manual stimulation and when feeling the remote vibrator insertion, were incredibly erotic, and the wetting scene was so stimulating that I rewatched it multiple times. The RPG-like element of one woman being thoroughly brought to climax and then used as a pawn to train new females was enjoyable; I bought it for Yuria, but the other performers were also outstanding. The selfishness of easily betraying others out of fear evokes a punitive feeling that 'she deserves punishment,' and when it's fulfilled, it brings an inexplicable thrill that's neither a sense of justice nor guilt. Though she should be a weak victim, she's a lewd wife who continues to climax even while spraying squirt and ruining a child's drawing, making it fitting that she gets thoroughly used, and this contradiction is amusing, allowing me to blame everything on her for enjoyment, hence the 5-star rating. Highlights like the scene where squirt drenches a child's portrait and the final remote vibrator moment are plentiful, fully immersing me in the three days of immorality unfolding in a daytime cafe.
