Custom clip request ''You are a teacher who likes kneeing men in the balls. You are dressed in a smart business suit with slit up the middle of the skirt, nylons and high heels. You practice kneeing at first - jabbing your knee up into the air leaving it there for a few seconds as you talk about your knee crushing mens balls and smiling as the collapse at your feet. you do this a few times before you notice that I have an erection from watching you. "I think your balls need crushing by my knee", you say. You approach me menacingly and then knee me several times in the balls''
