A light yuri SM story.

Gyaru is bought for one night, the rich girl works her over completely. She ends up going back every three days for more (no more money exchanging hands), and it ends with the gyaru declaring total submission. There's some light pee drinking.

Pretty good, looks like orgasm denial as well though I haven't translated any text.
