CUBE-004 - A summer memory! Couple hot spring trip with beloved girlfriend but... dream-like tanned 3 sisters harem hot spring trip!?

They try to bring out each performer's personality through drama, but the acting is subpar. The plot is about predatory women devouring men, but the cast looks like innocent 'little sister' types. This content requires sexiness, which all three lack. It would have been better if the roles were reversed. Also, the drama parts are too long, which makes the actual sex scenes painfully short—and that's what I'm here for. The final 4P is just a frantic, repetitive mess; you can really feel how hard the male actor is working. Mukai Kokoro is the billed lead, but the screen time is split almost equally among the three. The good part, as others have mentioned, was Okamoto Nana's solo segment. She's supposed to be the predator, but it was filmed as if she were the one being devoured. Again, the roles should have been reversed.

An erotic rom-com starring 'Kokoro Mukai', 'Nana Okamoto', and 'Kurumi Kashiwagi', who made waves with their triple debut. One day, the heroine 'Kokoro' arrives at a mixed-bathing hot spring inn with her beloved boyfriend. After arriving, she starts with an affectionate fellatio leading to an internal ejaculation. The two, whose desires were ignited by a 'strip-off' in the changing room, find the two older sisters waiting for them at the open-air bath. Despite this, Kokoro sneaks off to have hot spring sex with her boyfriend behind her sisters' backs. Meanwhile, the eldest sister 'Kurumi', having been 'shown' the act by Kokoro, commits the outrageous act of 'stealing her sister's lover' while she sleeps. Then, the busty second sister 'Nana' joins the sex battle. The second half develops into a massive hot spring orgy involving all the sisters over Kokoro's boyfriend. The chemistry shown in the making-of footage makes them seem like 'real sisters'.

The premise looked good at a glance, so I gave it a try, but both the actress and actor were so bad at acting that I couldn't get into it at all... Like other reviews mentioned, the actor has no charm and the plot developments make no sense. I wanted something more stimulating.

It's a production where the girl makes the moves, but the guy acts like he's so reluctant. He keeps putting his hands in the way, and his constant 'no, stop it' whining is annoying. There's too much of the guy's face and voice, and for starters, don't wear a towel in the hot spring. If the girl is supposed to be coming onto him, they should have given the guy some actual appeal. There's no reason for a girl to cling to a guy like that. They should have just used an actor with a huge penis and had the girl, who was attracted to it, get off repeatedly. The thrusting is monotonous; this production really wastes the actress. It's such a shame, especially since the actresses are cute.

None of the three are as pretty as they look on the cover. The only one who's decent is Nana Okamoto, and even she is an acquired taste. There's nothing particularly new about the content either; you can just fast-forward through it.
