I'm looking for a yaoi, do basically this black haired guy went to a club to sell his body and he gets banged by multiple people and they used toys, and then another guy comes and he is blonder and turns out they are classmates in the same university and he also sold his body cause he also failed a subject in their university. ++They dressed up as kuromi and my melody and the men took pics of them
