Yumi's peaceful life with her husband Akira is shattered when his younger sister, Yuna, moves in after running away from home. As Akira grows dangerously close to his sister, Yumi's jealousy spirals out of control. Her resentment only pushes her husband further away, leading him straight into the arms of his sister for a forbidden affair.








Kazama Yumi lacks delicate acting, which makes the whole production feel rough. Her overwhelming presence actually works against her here, and this film is a textbook example of that. If a more subtle and reserved actress had been cast, it would have left a completely different impression. Mizumoto Yuuna is perfectly cast, though.
I feel like the intense sibling incest between Yuna Mizumoto and Jitta Hanaoka is the only thing this work has going for it. Yumi Kazama isn't bad, but the premise is cliché and clearly lacks fresh ideas. It feels like they couldn't write a good script, so they just rehashed the same old tropes to fill the runtime. I didn't feel any of that 'new' eroticism that comes from chemistry with a co-star. Since Yuna Mizumoto doesn't do many incest works, it has some value, but for Yumi Kazama fans, it's just a standard, unoriginal affair.
With a star-studded cast featuring the mature Yumi Kazama and the in-her-prime Yuna Mizumoto, I expected a complex plot. Instead, it was structured as incest in the first half and sticky sex between two abandoned people in the second. While both gave great performances, I was let down by the lack of the revenge plot I expected from Yumi Kazama against Yuna Mizumoto. I was looking forward to seeing how Kazama would take revenge after her husband was stolen by his sister, but she just seduced the man the sister had already discarded, and there wasn't even a scene where the sister felt regret. I rewatched it several times to make sure I didn't miss anything, but it wasn't there. Mizumoto is excellent at playing submissive roles, and Kazama can play both dominant and submissive, so I was hoping for a revenge plot involving lesbian elements. Overall, it was a disappointment.
I had high expectations given the star-studded cast: the incredibly sexy mature actress Yumi Kazama, veteran actor Jitta Hanaoka, and Yuna Mizumoto. However, the plot involves Hanaoka's younger sister (Mizumoto) moving in with the couple. The first half features Kazama and Hanaoka engaging in sex, cunnilingus, fingering, and fellatio, followed by Mizumoto's masturbation and an incestuous encounter ending in a stomach shot. The second half focuses on Kazama seducing Mizumoto's husband (Tsuyoshi) under the guise of revenge; this segment alone lasts about 60 minutes, which felt a bit dragged out. Since all three were in the film, it would have been better to see a 3P or 4P scene.
The plot involves the husband's sister running away from home and suddenly having an incestuous affair with him. The wife, having witnessed it, ends up sleeping with the sister's husband. I bought this for Yumi Kazama, so I skipped the Yuna Mizumoto scenes. Yumi, after seeing her husband with his sister, seduces the sister's husband and engages in a jealous, frantic sex scene—it's incredibly erotic. They do so much deep kissing. The partner is an actor who frequently works with her; he doesn't do anything unnecessary and is skilled, fitting perfectly with Yumi's lead. From forcing him to suck her breasts to kissing while moving between rooms and grinding hard in the cowgirl position, the scene is long and features various positions. The way she wipes the cum from her mouth onto the sister's clothes at the end is just too lewd. Yumi's technique is masterful. Sorry to Yuna Mizumoto fans, but she's in a different league.
