Turn the restroom into a 'relief'-room.

I tapped my chin. Deciding to play around just a while longer, I had an idea.

On a twisted notion I adapted the purpose of the restroom into a more pleasant kind of relief, letting everyone know it without really making a big deal about it. Watching as Tessa walked past the other girl and out the door I made it so she too would mostly ignore my presence and stood with folded arms against the sink.

The girl walked in and found a stall. I waited. At first nothing appeared out of the ordinary. And then I heard rustling and squeaks against the toilet seat. I left the sinks, leaning my head down in front of her stall. At a simple glance it was hard to tell, and the angle wasn't optimal; the rest of her body was cut off. But then I saw her legs shifting and clamming together and her flats pressed against the tiled floor toe-first as her calf muscles tensed and relaxed, and so on. Then her panties fell carelessly over the top of her feet. I smiled as I heard a relinquishing moan echo past. Dead giveaway there.

Conceiving another idea, I compelled all girls who used this restroom to leave their panties in the new 'panty receptacle', and write their names on it with an attached marker. These panties would then be picked up by the janitors -- no, the president of the student body, and distributed to the girl's male classmates to sniff and smell and do as they please with it, which of course they wouldn't mind permitting.

A new sleek metal box appeared on the side of each stall interior that wasn't there before. Some with three panties, others with none, and others with the same number of fingers I had on both hands.

As harried breaths came audibly through the stall door. I stood up. I quietly reviewed my work.
