After actually watching this work, it's truly the definitive edition of dick training! The concept of three luxurious actresses—Kurata Mao, Konno Hikaru, and Amano Miyu—playing sex instructors to thoroughly train the viewer's di●k is outstanding. Kurata Mao's enlargement training using her beautiful buttocks showcases her whole body moving gracefully, stimulating the dick to its limits. In the intense collisions with Konno Hikaru, her slender figure intertwines flexibly, giving a sense of rapidly increasing endurance. Amano Miyu's continuous ejaculation scenes, fully utilizing her large breasts, are the pinnacle of stamina enhancement.

The harem play with the three in competitive swimsuits by the poolside provides the best aftercare and relaxation. The video quality is very clear, capturing the actresses' beautiful skin textures and subtle expression changes in detail, offering high visual satisfaction. On the other hand, the audio quality has some issues, with voices sounding muffled in certain scenes and noticeable indoor reverberation in some parts. This is particularly evident in Kurata Mao and Amano Miyu's segments, and compared to other companies' works, the clarity feels somewhat inferior.

However, the actresses' looks, proportions, and acting skills are flawless in every aspect, and with three actual sex scenes included, the cost-performance is exceptional. Konno Hikaru's cuteness and no-holds-barred passionate performance especially shine. The final foursome scene explodes with eroticism, fully demonstrating the actresses' high level and keeping viewers engaged till the end. Although it's a bit disappointing that the instructor outfits are removed early on, the depth of content and value for money are overwhelming. You won't regret buying this—it's a masterpiece with a masturbation score of 100!
