An: Do I need a warning?

*** CoS

"… the Slut Olympics." Harry said, smirking at the turned on looking girls.

"It will be recorded and sold for a galleon. The 6 of you will participate in several games and the winner gets to wear a bra and panties tomorrow, the rest of you will be naked."

The girls looked extremely turned on, Daphne's hand was between her legs.

"First task…" Harry said, setting up the camera, "You will bring yourself to the edge, then deny your orgasm, then repeat, whoever can do it the most wins and gets 1 point, whoever gives in first, loses and gets a clit-clamp that will be worn through tomorrow."

The girls nodded and grimaced at the idea of wearing the clamp the entire day.

Harry produced a fearsome clit clamp and then charmed it to sting permanently and put it down in front of the kneeling girls.

All of the girls stuck their hands between their legs, stroking themselves, splayed out in front of the camera.

Astoria reached her edge the first, being the youngest and least experienced, after a minute she started again, this time barely going before stopping again, on the third time, she started slipping her finger in and just about managed to remove it, on her fourth go, she came almost immediately, squirting all over her fingers, and gasping, her little mounds heaving as she lay cutely on the ground.

Gabi reached her first edge last, but having just matured, she only managed to go three times before she started sticking her fingers in, she just about managed her fourth go and came loudly and impressively on her fifth, just about making it past Astoria's four.

Ginny managed to go 5 times as well, the fiery redhead going all out, sticking two fingers in and trying to stop herself coming on her fifth go but failing, squeezing down on her fingers.

Susan reached her first edge third, and started rubbing herself again after a minute, she managed to repeat 5 times, before sticking her fingers in and just about managing to pull them out before her orgasm, she failed on her 8th try, giving her 7.

Hermione managed 8, before coming, her breasts heaving.

Daphne won the first round, having masturbated like this many times, and going on till 12, before sticking in 2 fingers and coming into her hand.

Harry found it amusing that one Greengrass came first and one last.

Harry chalked down 1 point under Daphne's name on a conjured board and then called Astoria forward, who was looking extremely nervous and had her legs pressed together.

"Legs apart" Harry said as he focussed the wizarding camera on Astoria's puffy pink lower lips.

Harry picked up the clit-clamp and stuck it on Astoria's most private nub, squeezing it hard and getting a shriek of pain from Astoria as the hex took effect.

Harry tapped his wand against the clamp and it gave a wave of pain in her pussy.

"You have to keep that on until midnight tomorrow, at which point, your pussy will be spanked and the clit-clamp removed, Harry said, making Astoria even wetter.

"Next up, we have Who can cum the fastest, where I will give you a dildo and you have to come, whoever comes first gets a point and whoever comes last gets these," at this Harry held up two extremely short ropes, "tied around their breasts, it will remain there until midnight tomorrow."

Hermione came last, she had the least sexual frustration and she went for a full 3 minutes, furiously working the dildo into her pussy like the slut she was, legs far apart.

Gabi came second to last, going for 2 and a half minutes, she came wildly and sprayed all over the floor.

Astoria came fourth, coming loudly and thrashing a bit.

Ginny got third, going for only 40 seconds, her cum spilling all over the floor as well.

Daphne got second, going for just about 35ish seconds before thrusting upwards with her hips, hard and coming hard.

Susan got first, the biggest slut of them all, she didn't even ease the dildo in, she thrust it into her hard and full for an impressive and transfixing beautiful 30 seconds of wonderfulness and she came hard.

Hermione gulped, she had lost and she knew what was going to happen.

Harry chalked up 1 point to Susan and then gestured for Hermione to come up front and take her punishment.

Harry took the short rope and tied it around the base of her boobs, it wasn't even close enough to going around properly, in this way, Astoria who had small boobs would have been better off with this, Hermione's were the second biggest in the group, only a bit smaller than Susan's.

Harry pulled the rope tight and tied it, Hermione cried out in pain as her breasts were squeezed outward, making them seem bigger and bulgier.

Harry smiled wide, "Now for the third game, who can clean up the fastest, all of you have to lick all the cum that fell on the floor and on yourself, whoever can lick the most off gets a point, whoever licks the least gets an enema in their bum and a buttplug that makes sure you can't push it out. There is a spell that tells me how much cum you have swallowed."

Harry did the complicated spell which put a red ranking above the girls, before they started, they all had 0 above their head.

Gabi was the slowest, she didn't mind cum but unlike Susan and Daphne, she wasn't extremely cum-hungry, she licked off herself slowly, wasting valuable time trying to lick off her pussy before starting on the floor, which she was very nervous about licking, she came last by a huge amount.

Astoria was also really gingerly licking the ground with her small tongue and screwing up her face at the thought of the dirt on the ground that Harry had specifically placed there. (the pain potion also included immunity to illnesses)

Ginny came fourth, she too had reservations about the huge amount of mud on the ground but went at it, because she had done it before.

Hermione came third, she wasn't cum hungry but she had done this before and took to it efficiently and fast, miles ahead of Ginny.

Daphne may never have done this before but she was positively starving for cum, she went down immediately, sticking her bum high into the air, where Harry smacked it and dragging her tongue across the floor and licking every drop of cum that she saw.

Even Daphne was not able to match the monster eater that was Susan, licking the ground, lapping like an excited dog, getting cum all over her face and body.

Harry chalked down a second point next to Susan who looked to be the winner so far.

He called Gabi forward, who looked extremely nervous to have her perfect arse touched.

Harry cst the augumenti spell and cast it directly into Gabi's ass, filling her up before sticking a huge butt plug in.

Gabi winced at the slight pain of the enema and the more immediate pain of having her ass violated by the butt plug and dreaded having it in till midnight the next day.
