I look forward to this director's future work. I felt that a slightly more delicate balance would have been better. In the first work, even within the businesslike atmosphere, I wanted a bit more emotional response. For the second and third works, it was a shame that the promising setups weren't utilized, ending up as very ordinary play. As for the final work, given how far the scenario progressed, I couldn't help but want to see her showing more signs of arousal with vocal reactions. That said, all the works shared a common flow of "initially handling things matter-of-factly as part of the job, but eventually succumbing to pleasure," and I strongly hope to see this pattern in more works.
There is no pleasure-induced downfall, but the level of completion is high. The three actresses each exude different charms, and I felt this was a very good work.
At the beginning, a scene is inserted where a man and woman, presumably new employees, are being explained that "this company has such duties," giving off a strange sense of realism. After an idling-like handjob for the male new employee, a sex verification is conducted by researcher Kudo-san and a mid-level male employee. Kudo-san remains calm throughout, maintaining a businesslike atmosphere while subtly exuding eroticism, which left an impression.
Next, in the sex verification between the department head and the male new employee, the man's gradual arousal feels realistic. The department head lets out a few sounds toward the end, but there is no kissing at all. Meanwhile, in the sex between the new employees (likely peers), they kiss and deliberately proceed with a lover-like atmosphere as initially discussed. After finishing, the man forcefully initiates a follow-up kiss, and only this pair continues kissing even during the subsequent 5P.
The final 5P also maintains the setting of "rubber quality verification," emphasizing a realistic feel that doesn't lean too much into typical AV tropes. It might be a bit lacking for those who prefer pleasure-induced submission, but the way each character breaks down according to their role is well-acted and directed. It may be coincidental, but I felt a high level of completion.
However, perhaps due to the setting requiring many fixed cameras, the angles are quite poor. The scenes with the peer pair are especially bad, with angles opposite to what I wanted to see, which was disappointing. That said, while it wasn't to my taste, the work's overall quality is high, and I rate it 4 stars for that. Honestly, I would have liked to see a few more scenes of them succumbing to pleasure.
