When Pr0n is Actually Touching

Keywords the reviewer selected :

Another one of System A.'s that I liked. It's hard to make porn at all heartwarming, especially with a threesome, but somehow this seems to have been managed very well.

It starts with a funny walk-in scene, but basically it's about the love triangle between younger sister, older sister, and the younger sister's schoolmate. Each longs after one and is chased by the other, so at first it seems like a pretty unresolvable situation, but they do manage to find a solution and make it work quite well.

Fair warning: There is some brief peeing in this, but I was able to get over it, so it's not that bad. It doesn't really take away from anything.
