"Muahahahaha!"

In the middle of the Old Quad, a large glass dome suddenly materialises. The floor of the dome is made from a soft, stretchy purple fabric, comfortable to lie on. Dildos, vibrators, feathers and other sex toys lie around inside, attracting the attention of the thousands of curious students who throng across the lawn at every hour of the day.

Two film students glance at each other, and begin to set up a live camera feed. They don’t expect to be disappointed.

There’s a flash of light, and a puff of smoke.

“Muahahahaha!” crows a demonic voice from nowhere, as a dozen or so beautiful, naked and very startled women materialise inside the dome. It’s obvious that they’ve all been caught in the middle of furiously playing with themselves.

Alice, caught two seconds from orgasm, squeals adorably and cups both hands over her wet pussy. Parvati and Fiona roll over each other in a confused tangle and scramble to their feet, hands flying to conceal their jiggling tits. The rest of the girls gasp, squirm, blush, try to hide behind each other. The audience reliably cheers.

“Masturbators!” booms the evil voice, to a rumble of applause. “Naughty, dirty, wicked, evil masturbators! Don’t try to hide it, girls! You’ve been exposed and you must be punished!”

There’s a chorus of shrieks from inside the dome as hundreds of jets of freezing cold water shoot up from underneath the fabric floor, unerringly aimed at the tits, pussies and asses of the unlucky nude captives. Parvati almost trips over Alice as she tries to get out of the way. It’s no use. Evading one jet of water only puts her in the way of another.

“Now,” croons the voice, as a big digital counter appears in midair above the dome. It reads 100, and looks like it’s been holographically projected from somewhere. The girls can see it if they look up. “You owe me tribute, girls. None of you leaves this dome until I get one hundred.”

“One… one hundred what?” Fiona, one arm cupped across her freckled tits, scans the leering crowd and bangs fruitlessly against the walls of the dome. They don’t give way. “Damn it! Let us out of here!”

“One hundred orgasms! Muahahahaha!”

“But… we can’t… but… what do you mean?”

The jets have stopped spraying. Fiona glances at Parvati. They both look down at Alice, whose eyes are wide as saucers as she huddles in a little ball on the floor.

Parvati nods.

They grab Alice. Pin her down on the soft fabric and **** her legs apart, baring her pussy to the cheering masses. Alice squeals with complete mortification, unable to fight back as Fiona licks her fingers and slides them expertly between the Korean girl’s soaking wet lower lips. Parvati licks her breasts, tongue tracing circles over her nipples as she wrestles with the girl to keep her in place.

She’s already on the edge. It’s not long before Alice’s whole body bucks in screaming orgasm, convulsing in mortified pleasure before the rolling camera and hundreds of ogling eyes. The other women in the dome are watching with fear, eyeing each other nervously, wondering who’s going to make the first move.

The digital counter clicks down to 99.

Parvati pauses, breathing heavily. Looks down at panting Alice. Takes a moment to think about just how long it might take to reach a hundred orgasms between a dozen girls.

Offers Fiona a sardonic smile. Then shuffles over, sits on Alice’s face and plunges her tongue into the Korean girl’s supersensitive pussy. Alice writhes in blissful **** as Parvarti’s expert tongue spirals around her clit, already on its way to forcing another explosion of pleasure out of her helples body.

Fiona’s on her way to help when two strong women, a Brazilian exchange student and a dazzling blonde from the women’s football team, grab her and haul her backward. One of them’s holding a big pink dildo. It’s going to be a long afternoon.
