This work kicks off with a senior's proposal to 'swap girlfriends,' starting as a game but taking an unexpected turn! The fair-skinned, droopy-eyed cutie 'Riko' is tossed around by a stud's relentless member, making hearts race. Her beautiful skin and well-toned lower body are flawless, and her exhausted expressions and poses after screaming are top-notch, offering great viewing value. Actual internal ejaculation would have been even better, but the direction by HiroA-sensei, known for clothed play and extended scenes, creates a unique atmosphere.

I initially expected more NTR elements, but the final scene with the boyfriend sleeping left me wanting. Adding another couple's sex scenes could have made the plot more dramatic. Still, the theme that a couple's longevity depends on the pleasure of H is profound, depicting the reality of losing due to compatibility gaps beyond just skills and personality. Riko's continuous moans, almost to the point of hoarseness, pulled me right in with her passionate performance.

The thrill of a seemingly innocent girlfriend cheating is perfect for NTR works, and I'm eager for more series. Overall, it has a typical Japanese AV style, but the acting where the actress demands internal ejaculation was a bit of a letdown. Learning from Korea's movie-like high-quality direction could elevate the work further. Even so, Riko's cuteness and HiroA-sensei's expertise make this piece worth watching. Definitely give it a look!
