After watching this work, the first thing I noticed was its unexpected approach to the theme of anal fetishism. The protagonist, Sanada, is humiliated at work when his sexual preferences are exposed by his boss, leading him to direct his anger towards the boss's wife, Rio. However, the story avoids anal sex or analingus, instead featuring extensive use of pinworm stickers, which stands out as a unique element. Initially, I was puzzled about how to interpret the 'anal lover' setup, but the continuous close-ups of Rio's beautiful anus, forced open while she resists and moans, created a distinct sensuality. Her anus, free from lesions, combined with her pudding-like buttocks, produced scenes that were both lewd and aesthetically pleasing.

Rio's anus is indeed very beautiful, and some viewers might have hoped for more direct anal stimulation rather than focus on the labia. The male actor's performance seemed to waver between emphasizing the anus or the labia, adding tension to the work. As a shaved actress, Rio strikes a perfect balance between cleanliness and eroticism, and I strongly hope to see her in more productions in the future. Overall, this work delves into the niche theme of anal fetishism from a different angle than conventional methods, leveraging the actress's acting skills and beautiful physique to create a compelling viewing experience.
