Rock

The pain throbbing between your legs clouds your judgement and your sister’s eagerness to quickly move on with the game despite your clearly agonizing ball pain angers you causing your fist to clench and play rock… again.

"Wow! You're so dumb. I can't believe you played rock again," she says as she holds her hand out flat like a piece of paper, steady and motionless. You can already feel your stomach churning from the assault your manhood is about to endure.

"I'm gonna enjoy every bit of watching your bits go flying from this..." Kathy says as she eyes your naked plums with an evil look in her eye. As her foot rockets toward your crotch you prepare for impact, but the bridge of her foot catches both of your balls dead center with a loud smack! Immediately, you curl up in a ball and wallow in self pity over your battered pride and joy while your sister stands over you laughing with her legs slightly spread and her hands on her hips, in less pain now than she was moments ago.

It takes you several minutes to recover. All the while she's jumping up and down, boobs bouncing and hair flying all over saying, "Again! Again!"
