Yes

You stop off on the way home to buy a few big boxes full of condoms, seeing as it seems you won't be able to stop Steve and his friends from fucking Katy and you didn't want her pregnant with someone else's baby on your wedding day. You get several boxes of large and extra large, judging that to be the most appropriate sizes based on what you saw at lunch. It costs you over fifty dollars in total, a good chunk of your leftover spending money for the month. You stash them away in your bag and head home.

The next day you're up early to get ready for morning band practice. You arrive with plenty of time to get set up, and Katy arrives shortly afterwards, dressed in her usual conservative outfit. You breathe a sigh of relief, at least she would be properly covered for band.

"Here, look after these," she says, putting her bag and clarinet case down next to you and pulling out a small bundle of clothes, "I need to get changed into these so I don't get in trouble from Steve."

"He just said you had to bring them, not wear them!"

"Oh did he? Well I don't want to get in trouble, so I better put them on just in case."

"I really don't think that's necessary, and what about the butt plug?"

"I've got that as well," she said, pulling it out of the bundle and rolling her eyes at you, "now where should I get changed?"

"I don't know, the toilets aren't open yet."

"How about in here," she said, reaching her hand toward the door of a practice room in which five of your fellow brass players were warming up.

"What? You can't get changed in front of them!"

"Well I can't exactly get changed out here in front of my future husband!" With that she opened the door and ducked inside, locking it behind her.

Her voice carried clearly through the door as she began talking to the occupants, but you couldn't here anything of what the boys were saying. "Sorry guys, I just need to get changed quickly --- Oh no, that's alright, it should only take a second --- Haha, thanks! You're too kind! --- Ah yeah, I guess that's fine, as long as you don't show anyone else --- I guess a quick video is fine --- Oh yeah, what sort of poses? --- Fine, but just for the video, don't push it in all the way --- Hay I said... Unnghh --- Quick pull out! You can cum on my tits --- Oh yes, that's it, cover them in cum! --- Ok, but after you I need to get dressed or we'll be late for band --- I know he got to go all the way in, but you're twice his size! --- Fine then, but make sure you pull out before you cum --- Mmm oh fuck, quick, pull out! --- Oh yeah that's it, cover my butt --- Actually, can you guys give me a hand with this --- No, it goes in my butt --- Yeah, you might need to help me stretch it out first. --- No sorry, I didn't bring any lube with me --- Oh yeah, that's a great idea, that should work great as lube, but you'll need to help me make more of it --- Yeah that's it, if you pinch my nipple and put the rest of your fingers in I'll make even more! --- Oh yeah, oh yeah, that's it! --- Ok, now get as much on your hand as you can and shove it in my butt --- Yeah, your whole hand --- Quickly, just shove it all in! --- Oh yeah! Oh! Mmm --- Ok, now shove the plug in --- Fuck! --- Yeah, I'm fine! Sorry, my legs just got a little wobbly there. Thanks for all the help guys, you're absolute lifesavers! And please don't share that video around, I'd do anything to stop it getting out!" You quickly jump away from the door and busy yourself setting up your trumpet as you hear her approach the door.

Katy emerges wearing the tiny, thin skirt and top from yesterday, made even more transparent by the cum on her tits and arse. She bends over to get her clarinet out of her case and you can see the absurdly large butt plug shoved up her butt. She made her way into the band room and quickly drew the attention of everyone already in there. You quickly followed her in. As she sits down there is an obvious clink as the butt plug hits the chair, and Katy lets a moan slip out as it is pushed deeper into her.

Throughout band Katy shifts uncomfortably in her seat, occasionally letting out a low moan. The cum dries on her clothes, which makes them less transparent, but also leaves pretty clear stains.

The bell rings and everyone rushes about putting instruments away and getting to their first class and Katy gets away without saying goodbye in the pandemonium. When you meet her for recess you can't help but notice several new cum stains on her clothes, as well as what looks like dried cum on her hair and face, and dripping down her thighs. When she sees you looking worriedly at them she looks apologetically at you. "Sorry hun, I had Maths with Steve and a few of his mates and the teacher was out of the classroom for most the lesson..."

"But they didn't..." you begin, trailing of nervously.

"Didn't what?"

"Ah didn't, you know, squirt anything inside?"

"Oh no!" she said, giggling a little with relief, "they only came in my butt, that's what is dribbling down my legs."

You breath a half sigh of relief.

"But Steve said I need to go see him now to get a new outfit, and that you'd better bring the condoms if you bought them."

The blood drains from you face and you follow her to Steve's usual spot. You hear loud squelching noises coming from Katy with every step, and more and more cum flows down her legs. The sight of her attracts the eyes of everyone you pass, and the noises attract the looks of everyone who didn't immediately see her.

When Steve sees you arrive he calls out to Katy. "Good thing we brought you a new outfit, cos that things more cum than cloth right now! Also," he says, turning to you, "I hope you brought some condoms, because I'm not sure how many people are going to be willing to fuck her in the butt with all that cum in there."

"Ah yep, they're just here!" you say quickly, hurriedly grabbing the boxes out of your bag and handing them to him. He grabs them and tosses them to his gang before turning back to Katy.

"Now why don't you get out of that outfit and then we can give you your new one."

Katy quickly stripped off her scant clothing, seemingly forgetting that you were still watching.

"But let's have a little fun first," Steve said with a menacing grin, tearing open a condom packet. "Now get over here!"

Katy nervously sidles over to him and Steve grabs her around the throat with one hand while freeing his erect cock with his other hand and barely managing to slide the extra large condom onto it. He then grabs her neck with both hands and pins her against the wall. He then thrusts into her in one smooth motion as her eyes roll back into her head. He begins violently thrusting his hips black and forward, pounding her against the bricks of the wall. Soon Katy convulses uncontrollably and lets out a high pitched moan through her constricted throat. Steve finishes quickly this time, pushed forward extra hard, before pulling out. He pulled off the condom with what looked like cup of cum in it and empties its contents onto Katy's head. He then hands her off to the next two boys.

They continued to violently fuck her for the rest of recess, emptying all their condoms onto her, leaving her completely covered in cum. They fuck her throat and pussy, shoving the emptied condoms up her arse. When the bell rings Steve hands her her new outfit. It consists of a tiny pleated skirt barely wider than a belt that covered basically none of her butt and just came to the top of her slit when pulled as low on her hips as it could go, and a tiny, thin blouse with barely enough material to be tied just below her tits. The top became even more transparent when it soaks up some of the cum covering her tits, clearly displaying her rock hard nipples. One of the boys shoves the butt plug back into her arse to hold all the condoms in.

"We'll see you back here at lunch, and make sure you come here straight away, because for every minute you're late I'll fuck you for one minute without a condom."

Katy nodded to Steve, looking over at you and giving you a quick wave before grabbing her bag and hurrying off to her next class.
