Paper

You choose paper. And your sister plays rock. Paper beats rock, and your pride begins to well up inside as a devilish smile spreads across your face.

“Oh, ain’t that too bad little sis,” you begin to taunt her. “Go ahead and assume the position while I get a running start. Just remember, this game was YOUR idea.”

You take a few steps back while your sister spreads her legs for you. You take a few steps forward and swing your leg hard bringing your foot up between her legs to collide into her pussy. You feel a bit of a squishy resistance between your foot and her pelvis, but she doesn’t seem to be in much pain aside from her wincing and groaning while rubbing herself.

“Okay,” she says moving on to round two, “you’ll be the one crying after this round.”
