Freshman Hazing! (Patreon)

Girls stand in a circle looking upon the transparent blue, makeshift wrestling mat. Within the blow-up colosseum, heaving and yowling, each girl fights for dominance over the other. The goal of the game is to completely immobilize your target with an atomic wedgie - an immediate out for the one stuck in it. The prize?

To enter the ranks of the prestigious sorority.

The pool serves duel purpose; it contains the girls and stops the baby oil from running all over the University's gym floor (reducing the risk of their hazing ritual getting discovered the next day). 

The sorority girls didn't want to make it easy on them, for only the best can join their ranks.

As motivation for the girls waiting to prove their worth, the losers who had their chance in the ring have their underwear tied to rope looped around the gym rafters. There, they dangle limply as their sore behinds work as bright red warnings to any potential losers.
