I remember reading some hentai online a long time ago that I need help finding again. The setting was in the future, and there was a heavy emphasis on sports. They were all basically naked, so the ground was designed to not hurt anyone who falls, and everyone rubbed a special cream on their tits to keep them perky. The two main characters were girls, might have been only girls in the story, and I remember it being in full color, being very well drawn, and the story being lengthy.
If you find what I'm looking for, I will post nudes. Pic unrelated.
