She starts to feel generous

"Snap, do you remember when I told you about the prize, Marchy?" Chels turns around suddenly just as you were about to take the stairs down to the second floor. The prize, oh the glow show one, huh? "Y-yeah, but I didn't Nick totally win it, I mean it was kind of cut short..." You blush as you remember Chels so horny then.

"That's right, she was supposed to get the prize, but technically she didn't win. I think the fact that the first person who got enough paint on the other that they got horny, wasn't the original plan, was it? Now, it's kind of sketchy, but doesn't that mean she didn't win?" She smiles kind of childishly and you can't help but get amused: "Ok, what do you mean?"

She taps her index finger on her cheek and points at you: "You helped me, I'll help you, fair huh? You get the prize, ta-da!" It sounds too random for her to be serious and you ask her perhaps a little too seriously as you get kind of nervous from remembering what happened in the showers: "Shouldn't we ask what Nick thinks first?" You are not sure what the prize even is and start sweating.

"March... uhh, I can tell why you don't have that many friends. You know, the way I do it is to not mix other people in other people's stuff. I can assure you that what she doesn't know, will not hurt her. She must be feeling sorry for me still anyway, and I don't want to act 'alright' with her yet, to let it play out. I just know it'll be alright." She crosses her arms and gives you a confident grin, which you dislike as you always think popular people tend to be arrogant.

"F-fine, but what is it?" You say and start getting uncomfortable just standing in the third floor hallway. "You will... ugh... I don't know, like it? It's just a little experiment. You will go to the one closet downstairs, just there next to the party room. It's really just a storage space for all the stuff we had to put away to make room for the dance floor. Well, it has that big door thing, so it looks like you can't get there or you are not supposed to get there, but here..." She stops her excited monologue to take a little key out of her purse.

"Here, you'll find the prize inside, oh, and watch out for the furniture, we packed them in tight. Have fun!" She drops the key in your hand and gets going while you wonder why Chels would hide the prize in there and not her room.

You go a floor down and actually see some girls dancing again to the place-holder music while Iris is setting up her stuff - you give her a smile which she returns with a wave. You feel kind of awkward by being all special and everything and wait for Iris to get her music backup and as everyone is focused on the DJ and not the busty wallflower with the Snow White costume, you open the sliding room dividing door and get in.

It's freaking dark as you quickly lock yourself inside thankfully the key still in hand - your phone becomes really useful with it's flashlight and you look around in the crowded space. There's chairs, tables and lamps and common stuff like that cramped in here. You are careful to walk around and look for the prize. Then your eyes catch something peculiar.

It's a paper with something written on it with a pink highlighter pen - the sheet of paper is crudely taped right in the wall at an awkward height. You have to squat down to read it: "Hello, lucky one! Behind me is a bit of a thin wall, it's the same wall that the WC has. What's also behind me is a hole, you are on this side so you must have something to put through that. Have fun ;)."

Your eyes get wide and your heartbeat slows down. You take the curious paper note off and sure enough there's a two inch thick wall beyond which ends in something metallic and loosely connected. You are sweating bullets and it's then when you clearly hear someone open and close the bathroom door. They lock it and sit just a feet away from you on the toilet you assume. You are so fucking nervous and horny that it's making your head hurt.

You shake it off and push on the metal plate which drops down after a good push, light pours in and there's a scream from the other side of the wall: "W-what the hell..." they say and get up after supposedly finishing their business. You are very nervous, but also sure that you could get away with it. You lower your panties and notice your cock is rock hard.
