Having actually watched this work that starts with a brother's impulsive act of assault driven by excitement over his overly defenseless sister's beautiful buttocks, it fully showcases the charm of Ms. Miyazawa Suzuki, who excels in beauty of face, breasts, and buttocks. The way the sister, initially resistant, gradually falls into pleasure is highly sensual, enhanced by her sexy moans, with the buttocks-focused scenes particularly arousing. However, it's disappointing that while the introduction and some scenes are shot normally, the main action features an abnormally high number of close-up shots of body parts, which even evokes frustration given the good setting—it feels like a collection of close-ups from old multi-angle shoots.

Still, in a word, it's 'quite delightful,' and among the recent trend of two-round works, the cleverness of the sister setting shines. The first round has a sudden insertion, so more creativity would have been welcome, but the second round, where the sister turns the tables and assaults almost like a reverse scenario, is thrillingly exciting. It's understandable to get excited when such a cute and defenseless sister is being bothered, making the plot convincing, and Ms. Suzuki is an actress I'd love to see in solo works. Overall, it's a good piece that leverages the setting and the actress's appeal, though the excessive close-ups are a slight flaw.
