DVDPS-570 - Extreme slippery lotion soap experience with G and H-cup beauties

I'd been hesitant to buy anything featuring Kei Sugiyama because she looked a bit harsh in her cover photos. I happened to get this as a prize, so I watched it without expectations, but she's actually quite cute. The angles emphasizing her breasts are pretty erotic, too. However, I'm deducting points because I'm not a fan of Azusa Mizuki.
