SLAP-043 - High school girl's insane masturbation: rubbing with a rope in tight gym shorts

As the title suggests, I'm one of those who were disappointed by that. The theme of gym bloomers and rope masturbation is good, and the model isn't bad either. But from the start, you can see these 'stain' marks, and sometimes they are even placed in awkward, misaligned spots. It would have been attractive enough without them, which is a shame. It would have been better if they just left it to chance—like, 'if a natural stain happens, that's a bonus!'
