After actually watching this work, the revolutionary high definition from AI mosaic and 6K filming immediately caught my eye. The heroine played by Melody・Hina・Markus, who is stressed about an upcoming big test and seeks stress relief from her smart brother-in-law instead of studying, has an excellent setup. The scene where she starts flirting with the protagonist and his privates suddenly enlarge is full of impact, and the deep-throat blowjob while kneeling conveys an intensity as if she's venting her stress. In the intense sex scenes, the role as a secret partner shines, with emotional highs overflowing from the screen.

However, as a fan, the teeth braces stand out too much in the VR work, detracting from the immersion, which is regrettable. With such high definition, the details become noticeable, making it hard to give a perfect score. Additionally, I could only understand fragments of the non-Japanese dialogue, missing some of the nuances in the lines. While the work's quality is high, the language barrier and minor details leave room for improvement. Overall, it's enjoyable for its high definition and passionate performances, but it didn't achieve complete immersion.
