Call her name

“Simon” Wham!! Before you can finish calling for her she kicks you full force in the balls from behind. You fall down holding your balls while on your side and see your sister furious but with a slight smirk standing behind the door.

“Fucking bitch! This isn’t the first time you have done perverted shit with me but it sure will be the last!”

She then proceeds to try and pry your hands away from your balls
