Shopping for an athletic cup is probably something a shy guy should do online, not with the hottest female trainer at his gym. Especially one with an appetite for busting balls and embarrassing weaklings. When scrawny Sammy timidly asks if any male instructors are on duty femdom fitness expert Penny smells an opportunity for humiliation. When she makes him admit that he is looking for crotch protection Penny knows this wuss is about to give her a very entertaining work day. He tries to just grab a random jock strap and slink away but Penny easily stops him and then just as easily strips him naked for a few ‘test’ shots. She makes him try on every athletic cup they have and each one gets tested with multiple kicks to the balls. While she is literally busting his balls, Penny makes sure to figuratively bust his balls with constant jokes about his small penis and overall weakness. After she has attacked his balls in every piece of equipment she can find, Penny brazenly teases his cock to an embarrassing erection and mockingly apologizes for only carrying Men’s athletic cups not Boy size small enough for him. Penny leaves him with a special message about the importance of cups for sensitive little crotches.
