A protective cup is an almost triangular piece of equiptment that boys wear over their balls to protect them. They are sometimes used in bondage for girls (or gay guys) to feel and stuff.
I was the target of an attack of these assholes in gym class. He took off his protective cup, gave me a stinkface and then made me wear his protective cup over my face. He taped it there and then he spanked me. The cup was over my mouth so i couldnt scream.
