Boarding School Piss Slave

(All characters in this story are 18 or over)

I have just joined a boarding school in the south of England, on scholarship of course, my parents could never afford to send me here, and I had joined at the beginning of the Autumn term. I didn't know anyone here, and I was really worried as I had spent my whole life being homeschooled by my mum, but after she got her new job she didn't have the time, so I enrolled for the final year at Oakwood College. I had been put in an all girls sixth form boarding house but everyone already knew each other from the years before so my first day was pretty rough but people were welcoming enough.

We all have to eat supper together in the house dining room, and it was pretty clear from the start that there was a pretty strict hierarchy in the year. Out of the ten of us in the upper sixth, four girls seemed to be the most popular. Ottelie was tall and pale, with dark hair that ran halfway down her back and piercing blue eyes, Bella was an athletic tanned blonde, with her hair almost always in a ponytail, Georgia had curly red hair and freckles across her face and arms and Mei was an international student from Hong Kong and had a petite figure and shoulder length black hair. They all shared a dorm that I would be moving into that night, and I was pretty nervous as to if they'd like me or not.

After the meal had ended, I took my bags from downstairs up to the dorm and started unpacking. There were five beds in the room, each with a desk and a large wooden cupboard next to them. They each had a pinboard decorated with posters and photos on the walls above their beds. After a few minutes, I heard the four girls coming down the corridor and soon enough they came in, giggling at something on Georgia's phone but they stopped after seeing me. 'Hi new girl.' cooed Ottelie, eying me up and down. 'What school did you come from?'

'I w-was um.. homeschooled.' I tentatively replied. Mei and Bella exchanged a glance and Bella whispered something in Georgia's ear. There was a dead silence in the air for a moment, before the girls went to sit down on their beds and whipped out their phones. I did the same, but kept watching them, noticing that Ottelie and Mei seemed to be texting each other as they kept looking over each other, glancing at me and then going back to typing. I felt awful. They already seemed to not like me, I could only imagine how bad the next year was going to be.

After a while, the house staff came to turn our lights out, but as soon as they were gone, Bella switched them back on. 'Here's the cinch new girl,' she purred, walking over to the foot of my bed, followed by the other girls. 'We could make or break your time here. We just have one thing we want you to do. If you do this, we'll make you so popular and the whole year will like you, maybe we'll even find you a fit boyfriend, but if you don't, then you're going to have a pretty bad time.' I gulped. This seemed like an offer I couldn't really refuse. 'What d-do you want?' I stammered. Georgia cut in. 'Let's just say, the walk to the bathrooms is pretty long, and those porcelain seats get quite cold on our arses in the winter, don't they?' The other girls nodded in agreement. 'So we were wondering if maybe, you could be our dorm toilet?' I was shocked but they seemed dead serious. Was this what girls at boarding schools were like? I didn't know what to say. 'If it helps you decide,' said Ottelie, 'Mei did this job when she first joined and look at her, she's one of the most popular girls in the year now, and you can be too.' I gulped. It seemed like I had to, it wasn't like I could change schools and I didn't want to spend the next year in total misery. 'Ok.' I mumbled.

All the girls beamed. 'Here are the rules then new girl,' said Bella. 'Whenever one of us needs a wee while we're in the dorm, you have to drop what you're doing and, well, service us. Don't worry, we won't use you if we need a shit, we're not that cruel. Once we've finished our piss, you lick us clean and then you're free to go.'

'One question,' I asked, 'what would have happened if I had said no?' Mei sniggered.

'We would have forced you to anyway.' I gulped.

'Well that settles it!' exclaimed Ottelie. 'Truth be told I'm dying for a wee. Get on the floor new girl.' As I did as I was told, Ottelie pulled down her stripey pyjama bottoms, revealing a set of black silk panties which she removed as well, revealing a totally smooth mound. Her pussy was neat, with her inner labia neatly peeking out of her outer lips. A pang of fear of what was to come ran through me 'Open wide!' she sung, squatting over my face. Staring with shock at her pussy, I wasn't ready for the stream to begin so when she released her muscles and started pissing, it shot onto my face before I adjusted and opened my mouth. I almost gagged at the taste of the foul liquid but I managed to swallow most of it, the pee I didn't catch dribbling down my face and into my hair. Her stream slowed to a dribble, and she sighed in relief. 'Clean me up then, toilet girl!' she ordered. I winced and licked the leftover urine off of her slit, the bitter taste of piss mixing with the sweet tangy flavour of her pussy. Laying there on the floor as she slowly stood up, I felt so used. Sure, I would get to be popular like them, but I'd have to be their toilet slave until someone new came along. She didn't have to do this, she got to be popular simply from being rich and pretty. It wasn't fair.

The other girls had been watching but had returned to their beds and continued scrolling on their phones. I got up, left the room and walked to the bathroom, the cold hardwood floors creaking under my footsteps. They were right, it was a long way to get there and after giving my hair a rinse and washing my mouth out, I finally sat down on the loo and got my phone out, ready to take a piss of my own. As soon as my arse touched the seat, a text from Mei came through: 'Come back to the dorms within the next 30 seconds or else, I need to go.' I wouldn't have time to have a wee and walk all the way back to the dorms in 30 seconds so I pulled my pyjamas up and hurried out of the bathroom back to the dorms. 'Took you long enough,' sneered Mei as I pushed open the door. 'By the way,' chimed in Georgia, 'from now on if we're in here after supper, you're not allowed to leave. We thought we'd let you rinse off the piss on your face, but from here on out, you have to always be ready for us to use you, otherwise the deal's off.'

'B-but I still really need to pee' I stammered. Mei walked over to me and leaned in close to my ear. 'New girl,' she whispered. 'You know how long I waited for this, how many hours I spent in here, desperate to relieve myself, how much of their piss I had to drink. But look at me now, I'm one of the most popular girls in the school and you are in what was my position. It's all worth it in the end. But for now, you will swallow my waste, you won't complain or leave and you will love it. Now get on your knees.' I nodded and obliged as she pulled her pyjama bottoms down to her knees, revealing a neat black bush of pubic hair and her brown pussy. She grabbed the back of my head with her left hand and pushed it into her crotch. As soon as my mouth formed a seal around her peehole, she released her muscles and piss began gushing out into my mouth. I had got the hang of swallowing piss now, and I managed to gulp it all down without spilling any. I gave Mei a lick, before pulling my head out from between her legs and pulling her pyjama bottoms back up.

I got back into bed and about half an hour went by, with them occasionally asking me questions about my life. The weird thing was, they seemed pretty normal, despite them all being quite posh, making me more confused as to why they were making me do this. I was starting to get desperate for a a wee by now, but Bella calling me from across the room signified that I couldn't abandon my duties. Without even looking up from her phone, she stripped off the onesie she was wearing, leaving her fully naked. Her perky boobs looked to be about a C-cup and her body was slim and toned, with long legs and tan lines that were evidence of hours spent lying in the tropical sunshine a a tiny bikini. She sat herself down on one of the two office chairs under her desk, this one being made of cast plastic, similar to a classic school chair. I realised after a couple of seconds that a square hole had been cut out of the flat base of the chair, and I quickly lay down and shuffled under it. Her shaven pink pussy and a sliver of her arsehole was all I could see, so I pressed my mouth into it, forming another seal over her urethra. Her piss, which came out slower than the other girls', was saltier and bitter, indicating she was more dehydrated. It was disgusting, but I got it down and sucked the droplets of urine and spit off of her vulva. She got up, giving me a full view of her whole crotch area through the hole, and zipped herself back into her onesie. I got up and tucked the chair back under her desk. It baffled me how she was so used to using another person as her toilet that she had made a special chair just to make the act of relieving herself in someone's mouth that little bit easier.

I climbed back into bed, the taste of stale urine still lingering in my mouth. I would probably have to get used to that. Another half an hour passed, and I was on the borderline of having an accident. My hand was pressed firmly against my pussy and my crossed legs squirmed to keep the boiling pee in my bladder from bursting out. 'Please can I go to the loo, I really need to go.' I whimpered.

'No,' replied Georgia, getting up from her bed. 'Because my need is greater than yours. You can go in the morning.' I was almost certain it wasn't, but I got up anyway and shuffled over to her bedside. She lifted up the oversized t-shirt she was wearing to reveal her pale freckled legs and her pussy, absolutely covered by a full messy ginger bush. Kneeling down, hand still pressed to my crotch, she turned around and stuck her bum out towards my face, arching her back and leaning on her bed like she was about to get taken from behind. She spread her arsecheeks apart, revealing her pussy. I put my mouth over her vulva, and she released.

The loud hiss of her wee escaping her peehole, combined with her sigh of relief was too much for me, and my muscles involuntarily relaxed, letting a violent jet of piss out of my bladder and immediately soaking my grey sweatpants I was wearing. I didn't dare let my mouth leave Georgia's pussy, as she was still peeing so I grabbed the plastic bin under her desk and frantically squatted over it, pulling my sweatpants and panties down as I pissed. 'She's having an accident!' giggled Ottelie as Georgia's wee subsided. I was still squatting over the bin and violently pissing into it, and drew my face from out between Georgia's arsecheeks. I realised with horror that Ottelie had filmed the whole thing. Fuck. This was my life for the next year- a life of bladder torture and toilet slavery to these spoiled bitches. Still pissing into the bin, I burst into tears.
