A lewd older sister corrupts her innocent younger sister behind their mother's back. What starts as a game quickly turns into an intense lesbian affair. From deep tongue kissing and fingering to 69 positions and strap-on play, the older sister takes complete control of her sister's first sexual experience.










The acting is naturally childlike, so I don't think it's bad at all. But is that breast size really appropriate for a little girl character? Some might like that, but if she's supposed to be a little girl, I wish they'd cast someone flatter-chested. Or maybe cast a busty actress as the older sister for a sister dynamic. That's the only disappointing part. That said, the interaction itself was a perfect blend of 'innocence and lewdness,' so I have no complaints there.
Irie-san is quite chubby, and since Shinomiya-san is so petite, she looks even bigger. Visually, I think the roles should have been reversed. The actual play felt a bit monotonous. Janes' loli-themed costumes are always a letdown because they try too hard to look childish, which just ends up looking tacky. Things like patterned sneaker socks—no matter how much the actress fits the loli type—just look out of place and unappealing. The lolita outfit and frilly socks in the first chapter were really cute, so I wish they’d stick to that kind of simple loli style.
Manami is a little bit chubby, so it depends on your taste. There's a bit more focus on her being on the receiving end of the yuri action, which makes for a pretty good performance. I wish there was more movement with the double-headed vibe, and the order should have been swapped—pen-ban play should come after the double-headed vibe.
