I watched the 6th installment of the first collaboration with 'Dasu!', featuring exclusive actress Akane Mitani, and the plot where she seduces a couple before their wedding as an esthetician is truly masterful. The scene where the couple drinks aphrodisiac-laced tea, their bodies heating up, and the woman is brought to climax by a male esthetician through a magic mirror, vividly portrays their descent into forbidden pleasure under temptation. Particularly, the boyfriend's inability to resist Mitani's exceptional techniques creates a tension that grips viewers.

Both actors exude incredible sex appeal, and as one comment noted, it's impossible to hold back once seduced by Mitani—her devilish charm shines throughout. The male esthetician having a larger penis than the client is a great touch, adding excitement through size contrast. While some wish there were more verbal teasing from the female esthetician, the current amount is already highly stimulating. The concept is top-notch, with no complaints about the situation, actress performances, or cowgirl positions, though suggestions to separate rooms and use more realistic windows for better authenticity are understandable.

This series holds great promise for the future, especially as skilled actresses in piston-style cowgirl positions are becoming rarer. Fans eagerly hope to see actresses like Ayaka Konami, Nozomi Ishihara, Sumire Kurokawa, Alice Nanase, Mei Itsukaichi, and Ayaka Yamagishi in upcoming works. The next installment is highly anticipated to refine things further. Overall, the dramatic flow of a couple succumbing to temptation before their peak of happiness expertly blends sensual excitement with psychological interplay, making it a standout masterpiece.
