I actually watched this AV work, which focuses on the cowgirl position, highlighting large and round buttocks, and initially, it built up high expectations. However, perhaps due to overemphasis on camera angles, the crucial hip movement scenes felt somewhat lacking. From start to finish, it was dominated by squatting positions with similar motions, lacking variety. I had hoped to see more cowgirl positions where the actress embraces the male actor and immerses herself in hip movements, but these were scarce, which might leave fans seeking high-quality hip action rather than just buttock size a bit dissatisfied.

The cast of five actresses is luxurious, each shining with their unique traits. Kyoko Misaki, unusually for this series, actively requested cunnilingus during the main scenes, fully showcasing her erotic appeal. Meisa Kurokawa had a rich variety of positions and angles, with the most refined hip movements, making it highly watchable. Rin Misaki used dirty talk to hype up the mood, but the voyeuristic camera work and the male actor's voice were somewhat annoying. Particularly, the male actor Ryo Sawai constantly made sounds and breaths, which was a major drawback since this series is known for its silent norm. If the male actor had been different, it might have earned a five-star rating.

In my personal 'ranking of who I'd want to be ridden like this,' first place goes to Kyoko Misaki, whose hip rotations while inserted were incredibly sexy. Second place, Reika Saijo, had fast piston-like movements that were full of impact. Third place, Minako Uchida, also had captivating hip sways, while fourth place, Rin Misaki, had a unique peeping setup but issues with camera work. Fifth place, Meisa Kurokawa, had good hip movements but felt slightly lacking in overall balance. Overall, the concept of focusing on buttocks is interesting, but the quality of hip movements and male actor's performance need improvement, making it a work worth checking out for fans.
