My little sister Ai was obsessed with her club activities, working late every day for the upcoming tournament. As her brother, Iโve always cherished her, even if I don't show it much now that we're older. But this summer, she got seduced by that total playboy in my class, and behind my back, heโs been slowly breaking her in and turning her innocent body into his personal toy.










The way she gradually gets more erotic feels so realistic, which is a huge turn-on. She really feels like someone you could encounter in real life.
This is a film about an innocent younger sister gradually becoming a slave to pleasure. I was turned on by watching her, knowing nothing, just going with the flow and falling into depravity. There was a moment where the brother's obsession with her peeked through, but unfortunately(?) he held back. It would have been even better if they had used that scene as foreshadowing later on.
I don't really get the content. I watch this studio's works often, but the Takemaru-senpai series was better. I'd really like to see that Mukai Ai one.
I had high hopes since it's JET's first 'stealing the sister' plot, but the buildup to the actual affair feels a bit rushed. As mentioned in other reviews, it might have worked better if the guy had been Takemaru-senpai. Giving it a generous 3 stars in hopes of better future releases.
