Damn, this was nice. Atomi Shuri is the sado-queen, and Hoshi Ameri is the maso bitch. There is no role swap. Atomi Shuri r3kts Ameri-chan non-stop. And that was a nice consistent touch that I liked.
Now the second girl, Hoshi Ameri, I barely knew who the hell she was. But as it turns out she is a pretty hot girl too. Atomi Shuri pounding her with a plastic dick was really nice.
