GDW-007 - Wife's Secret Request 07

Since the quality of 'Kaburitsukitakunaru~' and 'Hazukashii~' was so high, my evaluation of this work inevitably suffers. Those two works felt erotic, as if they had forgotten the camera and were truly immersed in sex, but this one feels a bit too much like 'just a job.' Has the freshness worn off as her filmography grows? If this were my first time seeing her, I'd give it 5 stars, but compared to the others, 4 stars is the limit.
