This work starring Satsuki Nanao, with the setting 'When I visited my girlfriend's house, I met her busty younger sister for the first time,' I actually watched it, and it was a huge hit!

Starting with Nanao's looks, she has an incredibly cute face and a beautiful body, with natural large breasts that sway perfectly. The visuals of her fair skin with larger areolas peeking out are top-notch quality, and the many subjective scenes are a great touch. Especially the line 'Your dick is hard' early on gets you excited just hearing it. The way she talks gives off a vibe like she's with a younger guy, and although she's set as the 'younger sister,' it feels more like a younger brother, which is refreshing.

The content follows the usual cheating pattern, but the development of sneaking sex all the time—while cooking, bathing, or after the older sister falls asleep—without getting caught, makes it impossible to stay rational with Nanao tempting with her exposed chest. The jiggly breasts and well-shaped butt are frequently highlighted, making you want to burst each time. With soft breasts and butt, no pubic hair, tall and fair-skinned, her body is perfect and ideal for this series.

The only downside is that in the ejaculation scenes, the semen doesn't shoot out forcefully, so the pleasure isn't fully expressed, ending a bit blandly. Still, the scenes where he cums multiple times on Nanao's cute face are satisfying just for her looks. Many bought it based on the cover, but the actress's quality is high, leading to no complaints. I first bought it during a Satsuki Nanao sale, and with full subjective views and some clothed play, it's highly satisfying. The swaying breasts are never boring—I could watch them forever!
