Rock

Rock is always a SOLID choice right? Your pun makes you have confidence in your decision and you throw rock.

Unfortunately so does he

"So what happens if we tie?" you ask "Is that just a redo or-"

You get cut off by your opponent suddenly grabbing your sack

"We both get a 10-second grab" he says with a smirk

"Well, shit. Who would of thought a tie would be worse than a loss" you reply

You grab him by the crotch as well

"On 3" he says

"1....2...."

Before he says three you already feel his grip tighten immensely around your balls.

You reflexively do the same to him, but although you find yourself straining to not cry or vomit you feel him getting hard which actually causes you to lose your grip
