MMR-AA163 - Yamazaki Mia: My Little Sister

This is my first time watching her work; she's cute, has a decent figure, and only shows a little skin, so shouldn't this have been released as a standard title? I feel like there have been more extreme standard releases before. I wish they'd watch more of her work before deciding on the rating. If it were a standard release, I'd give it full marks, but as it stands, I have to be harsh with my rating.
