Tickle Test

"Are you ready for your test, little guy?"
Oh my god, there's more? You thought this was the test! How else could they possibly make this worse? You're going to regret asking that.
"Here are the rules: Jill here is going to tickle your armpits for an amount of time that only I know. You will not know when she will stop. If you fall to the ground or put your arms down, you will have failed the test and there will be a punishment. Hopefully you won't have to find out what that punishment is, but it's going to be worse than all these girls seeing you like this, so you can just imagine that while she scratches at your wide open pits... Oh, and she just got her nails done so they're nice and long and sharp. Good luck. Girls?"
Jill gets in position, which is unfortunately behind you so everyone can still see your little tiny bulge after she starts.
"3..."
She places her nails on your triceps and you are already squirming in anticipation.
"2..."
The nails start to spider down and you can't hold in little bursts of laughter, she hasn't even reached your most ticklish spot yet. Did they know your armpits were your most ticklish spot?
1!"

"HAHAHHAHHSHAHHAHA OH HAHAHAH FUCKD NOOOOOOO HAAHHAHAA PLEASEEEEEEE STAHPPPPP HAHAHAH"
