With the family away, lesbian couple Mizuna and Yua are caught in the act by Yua's twin sister, Yui. Though shocked, Yui finds herself strangely aroused by the sight. Sensing Yui's hidden potential, Mizuna decides to pull her into their intimate world.




















Even with the body-swap concept, it's just Mizuki and Yua having sex, so there's no real novelty to it.
If you're going to use the 'she hasn't showered' trope, you shouldn't have him smell her and say 'it smells good.' You need to have him say 'it stinks' for the premise to actually work.
Mizuna Wakatsuki... she's quite tall when standing next to the other girls. Having Yua Imai play twins in a dual role was a good idea. I was looking forward to seeing Yua Imai's range, with the older sister being a perverted lesbian and the younger sister being a super serious girl in glasses, but once the sex scenes started, they were exactly the same. It was a bit disappointing—the setup felt pointless.
I watched this because I like Wakatsuki—she's a talented actress with plenty of experience in lesbian films—but personally, I found Imai Yua to be the highlight here. She has that 'possessed' acting style that doesn't feel like she's just 'doing a job,' and her passionate performance is very appealing. As for the twin concept (swapping sisters), it seems younger users who aren't familiar with the old U&K 'Lesbian' series don't quite get it (lol). For those who know the source material, the twin-setting direction was actually quite elaborate and well-done. Strictly speaking, it's not a direct swap, but since the packaging spoils it anyway, I guess some naive viewers might feel misled.
I bought this based on the title, but the story is forced and the only thing emphasizing the 'twins' aspect is a pair of glasses. They never even appear on screen together, so it's totally unsatisfying. Also, the 'body swap' premise is a lie—there isn't a single scene where they actually swap. Watch it if you really want to, but don't say I didn't warn you.
