Watch the experiment unfold

At first the Eels seem to have the upper hand.

As the ball pops back and forth across the net, the Sharks begin to notice an uncomfortable tightness in their nether regions. Bubble squirms as her shorts slither between her buttocks, baring more and more of her pert, round posterior. You can see her ass flex as she leaps across the court to spike the ball into the air.

The Eels send the ball flying back, and the girl with the dark blue ponytail scrambles to get it. A hit is followed by a squeal as her shorts contract a little more, reducing the lower half of her uniform to little more than a thong. You can tell the Sharks are growing more and more self-conscious, picking at their clothes, and letting their hands rest behind them, trying to conceal their cheeks without drawing attention to themselves.

It's not working. You let your eyes drift across half a dozen beautiful girl bottoms, now almost bare to the world. Bubble's is especially lovely. You hear a few wolf-whistles from the crowd, as some of the bolder men in the audience draw attention to the spectacle.

It hasn't slipped by the Eels, either. Meadow's eyes narrow, and she aims a shot to the left of Bubble, making the girl reach to get it. The sudden motion almost causes her breasts to pop out of her rapidly shrinking sports bra, which is baring more and more cleavage to the world. Bubble, furious, just manages to tap it back over the net.

Meadow smirks, watching the nervous Sharks pull at their tops. "What's the matter, girls?" she teases. "Having a little wardrobe malfunction?"

Then her shorts drop down around her knees.
