STSK-182 Corner masturbation fetishism I just want to defile a slender high school girl as my desire dictates.. “Corner masturbation” is the most embarrassing type of masturbation and you don’t want anyone to see. It’s a different kind of masturbation from other people. My own secret. My sexual preference. The corner and me. The most erotic and daring type of masturbation. I observed four slender girls masturbating with a corner at home, cumming defenselessly. And I just wanted to devour those girls as I pleased. I wanted to defile them.
