The next Monday afternoon came round at Wamsthorpe Sixth Form College, and 18-year-old hottie Nina was on detention again. The only difference was that this time, she knew it was all an act. Miss Pye had deliberately 'spotted' her talking during her lesson the previous Thursday. To anyone not in on what was happening, it was a completely unfair detention, and some of her classmates had told Nina that they felt she was being picked on by the teacher. Only she and Miss Pye (and, to an extent, the headmistress) knew, however, that 'detention' was merely a code word for 'WAM session' between the two of them.

There was still an element of the unknown though. Would she be the one getting messed up this evening, or would it be Miss Pye? Or maybe both of them? What type of gunge would be used? What would Miss Pye be wearing? Would there be any role play? All these questions yet to be answered made the experience all the more exciting.

Nina stood at the door to the Geography Room as she had become used to doing and waited for Miss Pye to catch her glance. As usual, the teacher looked stunning. She'd adopted quite a sporty look today, with a tight-fitting white T-shirt and sexy denim jeans. The only non-athletic part of her outfit was a pair of black high heels.

"Aha, Cartwright!" she said, raising her eyebrows. "In you get, you naughty student!"

Nina energetically entered the room, shutting and locking the door behind her.

"Disgraceful behaviour from you again last week, young lady!" tutted Miss Pye.

"But I wasn't even talking, miss!" Nina protested. "You're as blind as a bat!" Her relationship with Miss Pye was now good enough for her to get away with this sort of banter, but the teacher still gasped, feigning shock.

"How dare you answer back like that?" Miss Pye seethed. "I'm really going to punish you, Cartwright!"

"Oh, I'll answer back alright!" retorted Nina. "With 20 pies in your face!"

Miss Pye broke character, relaxed and started laughing. "Well, I can see neither of us are going to back down here!" she said, as Nina laughed too and shook her head. Miss Pye reached for her handbag.
"Tell you what," said the teacher. "How about we toss a coin? Heads, I pie you. Tails, you pie me."

"Deal!" Nina said. She honestly wasn't sure which scenario she was hoping for. Either would be really sexy, and great fun. Miss Pye was about to toss the 10p coin in her hand, but then the phone on her desk rang. Most classrooms in Wamsthorpe had those phones on the desks, but they were only used internally and didn't often receive calls.

"Oh, fuck off!" she scoffed, which made Nina laugh. It was pretty funny hearing Miss Pye swear. To her classmates, Miss Pye was stuffy and strict, but Nina had seen a human and very sexy side to her. Despite the unwelcome interruption, Miss Pye answered the call.

"Hello?" said Miss Pye into the phone. "Hello?yes, yes I amyes, Cartwright is with mewe are, yesright?Right, OK then, if you think so OK, we'll be there in a moment."

Then she put the phone down, her expression changing from playful to serious and worried.

"That was Mrs Green," Miss Pye explained. "She wants us both in her office immediately."

--

As she and Miss Pye made their way wordlessly to the head's office, Nina once more was consumed by that feeling of nervousness and dread that had become all too common since after-class girl-on-girl WAM had become part of her life. But what was the problem now? It seemed like they had got away with it last week, but maybe the head had had a rethink and decided that what they were doing was unacceptable.

The walk to the office seemed long and tense. Finally, they reached the mahogany door of the head's office, which was decorated with a rather grand looking sign reading MRS. L. GREEN HEADMISTRESS. Miss Pye knocked timidly on the door.

"Come in!" boomed Mrs Green. Miss Pye walked through first, with Nina slinking in behind her.

"I'm a little confused, Mrs Green," said Miss Pye. "My understanding from last week was that you were happy with what we were doing?"

"Oh, I've no problem with it at all!" said Mrs Green, then she smirked menacingly, "but after that little dressing down you gave me last week, I just thought I needed to even up the scores a bit!"

Nina and Miss Pye turned to each other and gave nervous smiles, as if saying "uh-oh", then turned back to the headteacher.

"Strip to your underwear," Mrs Green ordered. "Both of you."

"Now?" Miss Pye asked.

"Now," Mrs Green confirmed.

Nina's heart beat faster as she realised she was going to get messed up by the head while semi-naked. Miss Pye had already kicked off her heels and was in her bare feet. Nina opted to start undressing by lifting her blouse over her head, showing off a brand new blue bra she was wearing. Nina couldn't help glancing over at Miss Pye and her gorgeous body. The teacher had now removed the T-shirt and was in a wine-coloured silk bra. Then she unzipped her jeans and stepped out of them, revealing herself to be wearing knickers that matched the bra. "God, she's fit!" thought Nina, but she looked great in her underwear herself. Indeed, Mrs. Green, who clearly had something of a queer eye, must have struggled to decide which one of them to leer at first.

Nina unbuttoned her skirt and finally removed her shoes and stockings. She stood in front of the head in her new blue undergarments, with her toenails painted blue as well, and waited for the next step. It was nerve wracking, but that was all part of the fun of getting pied and gunged, she decided.

"Looking good, ladies!" said a clearly impressed Mrs. Green, nodding. "So, now that you're in your skimpies, I've got a little messy challenge for you both. You're the teacher, Miss Pye, so you can go first. Cartwright, take a seat for now, I shall deal with you later!"

Nina sat down on a leather chair and crossed her legs. Her messy time would come but, for now, there was an opportunity to sit back, relax and be treated to the spectacle of the scantily clad Miss Pye getting a good messy session.

"OK, here's the deal, Miss Pye," explained the head. "All you have to do is guess what the gunge is in the bucket!" She held a bucket aloft, but kept the colour and consistency of what was in it guarded from Miss Pye's eyes.

"Oh, that will be easy!" scoffed Miss Pye, "I'll know as soon as I see it."

"Oh, did I not mention" said Mrs Green sarcastically, as she held up a blindfold. She walked behind the half-naked teacher and tied the blindfold tightly across her eyes, cackling as she did so. "You don't get to see, and if you get it wrong, I'm going to pelt you in the face with pies and cover you in gunge!"

"Well, then I suppose I have to feel the gunge?" asked Miss Pye.

"Well, in a way, yes," said Mrs Green, "but there's a reason I've got you in your bra and knickers."

"And what would that be?" Miss Pye asked naively.

Mrs Green stood in front of the blindfolded Miss Pye and turned and winked at Nina. Then she pulled at Miss Pye's bra, peered down at her bare breasts and poured the contents of the bucket over them."

"Ohhhhhhhhohohohoh!" moaned Miss Pye. It sounded cold, Nina thought, and from the runny yellowness of it, it was obviously custard. Miss Pye tilted her neck back, opened her mouth wide and gasped as the custard ran between her tits, down her chest and towards her knickers.

"No idea, Miss Pye?" teased the head. "Let's try down here instead!"

Nina saw Mrs Green tug at the front of Miss Pye's knickers, then dump another helping of custard down them. Miss Pye gasped even shriller, and Nina started to get really turned on. It was a cool thought that Miss Pye was getting custard all over her cunt, and that the same thing would soon be happening to her.

Mrs Green let go of the knickers and let them snap against Miss Pye's waist. The custard spurted out of them, dripping down her legs and towards her feet.

"OK, Miss Pye, it's time for you to have a guess!" said the head.

"Er, I'm gonna guess strawberry mousse?" said Miss Pye hopefully. She was going with the predictable option following the gunging she got at the hands of Nina last Monday.

"Well, take off the blindfold and see if you're right!" said Mrs Green.

Miss Pye eased off the blindfold and saw the thick yellow slop all over her tits, belly and legs. "Custard was going to be my second guess!" she protested.

"Not good enough, Miss Pye," she said, picking up a chocolate cream pie. "You got it wrong, and what did I say would happen if you were wrong?"

"Er, I'd get pied in the face?" said Miss Pye, hands on hips.

Mrs Green sighed, and slammed the pie hard into the face of Miss Pye. The chocolate cream splattered all over the blackboard behind her. Nina laughed and applauded watching Miss Pye get pied was fun and sexy.

"And what else?" prompted Mrs Green.

"Erm, do I get gunged as well?" Miss Pye asked.

"You sure do," said the head, and swiftly dumped the remainder of the bucket over Miss Pye's head. Miss Pye closed her eyes and opened her mouth into a gleeful smile as the custard glooped down her face.

"Ha ha, that's what you get, miss!" Nina found herself shouting.

"OK Miss Pye, I'll finish you off later, but take a seat for now. It's Cartwright's turn!" said Mrs Green.

Nina sprang to her feet and now it was Miss Pye's opportunity to gloat. "Yes, get her good! She deserves it!" taunted the teacher.

This back-and-forth banter really got Nina horny. Watching Miss Pye get messed up was great fun, but being on the receiving end was just as enjoyable. Here she was, in the headmistress' office, in her underwear and about to get gunged in front of her taunting teacher. This was so hot!

It was also, when Nina thought about it, very kinky and taboo. There were three levels of hierarchy here and it was such an inappropriate setting. At a traditional college like this, all hell would break loose if knowledge of this were ever to be made public.

But what, really, was so wrong with it? Nobody was doing this against their wishes, they were all over 18, they would clean up after themselves and they were just having some sexy fun. What harm was that to anybody else?

As Nina was thinking this, Mrs Green was securing the blindfold around her head. "It's going to happen!" Nina thought to herself, "I'm about to get the gunge down the bra and knickers treatment!"

"Same rules for you, Cartwright!" she heard Mrs Green say, "guess the gunge, or face the punishment!"

Nina felt her bra get pulled at and a healthy dollop of gunge get plonked onto each tit. The first surprise was that her gunge was warm. Warm and stodgy. A good tipping of it then went down the front of her knickers, giving her a gloriously warm and slimy feeling around her nether regions. Nina gasped and laughed.

"Cartwright! I need an answer, young lady!" Mrs Green barked.

"Umrice pudding?" guessed Nina. What the hell, she hoped she was wrong. She didn't want to weasel her way out of more messiness.

"Final answer?" asked the head. "OK, remove your blindfold!"

Nina took it off and looked down. It didn't look like rice pudding. It was thicker and oatier. Porridge, it had to be!

"Oh, bad luck!" mocked the head. On the word 'luck', she hit Nina hard in the face with a sloppy custard pie. Nina opened her mouth at just the right/wrong time and copped a big, delicious mouthful of the filling. Now it was Miss Pye's turn to clap and whoop.

"Let's not waste the rest of this porridge either!" said the head, dumping the rest of it onto Nina. Nina groaned and looked up, sportingly getting the gooey oats all over her face.

"Right, get back over here, Miss Pye!" said Mrs Green. "It's time for you both to get punished together!"

Miss Pye skipped back over to the centre of the office. Mrs Green had the pair of them totally under her control, and they were enjoying every submissive second.

"So, where shall we start?" said Mrs Green, with a huge cream pie in each of her hands. "I know get your tits out, girls!"

Nina slid her hands towards her back and unclipped her bra. Miss Pye did the same and the two of them let their bras fall to the ground in unison as their breasts bounced in front of them.

"Very nice!" grinned Miss Pye. "But which knockers shall I pie first?" She eyed Nina, then Miss Pye, then Nina again, then Miss Pye again, then SPLAT! A pair of creamy pies smashed and rubbed all over Miss Pye's big tits.

"Oooohhhh, that's good!" panted Miss Pye, as the head smeared the pies across her norks. Nina was really looking forward to the same thing happening to her and, sure enough, SPLAT. Nina's bare nipples hardened as the head ground the cream pies across both her beautiful breasts.

Before she knew it. Miss Pye was behind Nina and had a hand on the back of her knickers. "Yoink!" she said, and pulled down the knickers of both her and Miss Pye. Both women were now naked, and received a custard pie to the bare arse for their troubles.

"Aaaaaahhh hahahaha!" said Nina. It was a surprise, but a sexy and funny one. While she was she making that noise, Mrs Green planted a banana cream pie into her face.

"How was that, Cartwright?" asked Mrs Green.

"Delicious!" said Nina. It was too! She licked up the banana cream around her mouth and cleared her eyes just in time to see Miss Pye get a facial as well, only hers was gooey purple blackcurrant.

"Now pie each other!" the head commanded, handing each of them a custard pie. Nina and Miss Pye grinned at each other menacingly before thrusting out their arms and delivering pies to each other's faces.

"Oh, this is too much fun!" laughed Mrs Green. "Now get down on your knees both of you!" she said sternly.
Obediently, both women sank to their knees and waited to find out what they were to be subjected to next. Miss Green produced another two buckets of gunge, this time green cake batter, and placed one in front of each of her victims.

"Let me explain, girls!" said Mrs Green, pushing her spectacles further up her nose. "We're going to have a competition now. After three, both of you are to dunk your head into the bucket in front of you and hold your breath for as long as you can. The first one to surface will be subjected to a pie and gunge bombardment."

Nina licked her lips in anticipation. She loved a bit of competition, a bit of tension.

"Ready? 1, 2, 3.dunk!" called out the head.

Both girls took a deep breath, launched forward and weren't shy about dunking their whole head into the slop. Nina shut her eyes tight and heard all the sounds around her become muffled as the thick, sweet-tasting slime flowed all around her. Up her nose, into her eyes and deep into her hair.

She had no idea how long she had been in the bucket, but she was going to need to surface for air soon. She was a bit smaller than Miss Pye, so the teacher probably had a bit of a lung capacity advantage. She pulled out, took a few deep breaths and cleared here eyes of the gunk. She wasn't surprised to see that Miss Pye had outlasted her and still had her head in the bucket.

"You lose, Cartwright!" said the head, just as Miss Pye emerged from the bucket herself. Dripping with green gunge, the teacher cleared her eyes, spotted Nina already out of the bucket and pointed and laughed at her.

"Care to join me in splattering this ill-disciplined girl, Miss Pye?" asked the head.

"Well, there's an offer I can't refuse!" replied Miss Pye. Both women picked up a bucket of the green gloop and emptied it over Nina. Still on her knees, Nina felt the gunge splash into her face, cascade down her shoulders and coat her tits, chest and legs.

"My face!" shrieked Nina, "I spent hours on my make-up this morning!"

"Aw, you poor thing!" said Miss Pye. "Here's a nice facial to make up for it!"

She pied Nina hard in the face with a runny cream pie, and Miss Green followed it up with a gungy lime pie with a floppy, pancake-type based.

"Eurghh!" moaned Nina, acting as though she didn't like it. She stuck her tongue out and lolled it from side to side, then she got pelted with chocolate, custard and banana cream pies, with about 15 of them dished out by the two teachers and smothering her face and tits. When the ambush was over, she collapsed onto her back, a pie-smashed, naked mess.

"She looks a real treat!" said a very horny Miss Pie. "I'm going to have a taste!"

Just like last week, Miss Pye climbed on top of Nina in the 69 position, and the two hot WAM-lovers felt their clits teased by each other's tongues. Nina, who was already soaking wet down there, was determined to make Miss Pye come first this time. She gently sucked the teacher's clit, curling her tongue into a U-shape underneath it and sliding a couple of fingers up her vagina. As well as Miss Pye's panting, Nina was sure she could hear Miss Green moaning as well.

"God, Cartwright! I fuckin' love it!!" she screamed. The teachers pussy juice squirted all over Nina's face, and the excitement of it all caused orgasms to rocket through Nina's body too. Totally out of breath, Nina and Miss Pye plonked themselves into the pool of mess that had been created.

"Excellent show, girls!" remarked the head, with a smile on her face. "Class dismissed!"

"Er, no I don't think so!" Nina replied. "I'm not sure we're quite finished in this office!"

"Whatever do you mean, Cartwright?" snapped Mrs Green.

"Oh, I think you know!" taunted Nina, then she turned to Miss Pye. "Shall we strip her naked?"

"Oh yeah, I think we should!" said Miss Pye slyly.

Mrs Green took a step back and turned her head back and forth between the pair of them. "No, you would not DARE!" she blurted, with pantomime sternness.

"Try us!" laughed Nina. She grabbed Mrs Green's gown and yanked it off, then hoisted her shirt over her head, leaving her in just her bra. Miss Pye then grabbed the head's feet and the pair of them lift her onto her desk. Miss Pye pulled off Mrs Green's heels and trousers, leaving the head in her underwear. Just like with the splattering she took last week, Mrs Green was huffing and puffing as if outraged, but was doing nothing to resist the treatment at all. The head was wearing really sexy leopard-skin underwear, but tragically, that was going to have to come off too.

"I've got the bra, you get the knickers," Nina said to Miss Pye. Simultaneously, they pulled the garments off, exposing Mrs Green's gorgeous naked body.

"Looking sexy, Mrs Green!" said Miss Pye. "Now flip onto your stomach!"

Mrs Green harrumphed, but did as she was told, kicking her legs up above her curvy backside.

"Are you thinking what I'm thinking, Cartwright?" asked Miss Pye.

"I reckon so," said Nina. "Let's hog-tie the head!"

Nina rummaged in the draw in the desk and managed to find a big roll of Sellotape. She had found something else in there too, which she was sure would come in useful later. She pulled off a huge length of the tape, held Mrs Green's wrists against her ankles and wound the tape generously and tightly, sticking her hands and feet together.

"We could make a game of this too, Cartwright!" said Miss Pye. "I'll tickle her feet, and if she laughs, you can pie her in the face!"

"An excellent suggestion!" nodded Nina. Straightaway, Miss Pye flurried her hands across the head's wrinkled soles. Mrs Green puffed her cheeks, closed her eyes and tried desperately not to giggle.

"Go on, let it out!" Nina teased, as the head managed to just about keep the laughter at bay. Miss Pye worked her way up to the toes, digging her fingers deep underneath them and teasing Mrs Green's most ticklish areas. Finally, it was too much for her.

"Hahaha HAHAHAHAHAHHAHAHAHA! GLUMPH!"

Mrs Green copped a massive, sticky chocolate cream pie in the face. Nina lost all control as she smashed banana cream, blackcurrant and custard puddings into the head's face and on top of her head. All the while, the head giggled incessantly, clearly both enjoying getting pied and affected by the ticklishness of her bare feet.

"I want a go at pieing her!" said Miss Pye. "You get her feet!"

Nina swapped places with Miss Pye, smashing a custard pie into Mrs Greens upturned arse as she made her way to her legs. She pulled at the head's toes, making her soles flat and fully exposed, then tickled around the balls of the feet. The head's continued tittering was stifled by a barrage of pies to the face from Miss Pye. Then, Miss Pye lifted up another bucket of green cake batter from beneath the desk."

"What d'you think?" she asked. "Time to turn Mrs Green green?"

"Hold on for a sec!" replied Nina, remembering what was in the drawer. "I've got another treat for her first!"

Nina opened the drawer and produced a huge, ribbed dildo. "Fancy having one of these in your office, miss!" said Nina with mock disappointment.

Mrs Green turned her head, barely able to see past all the pie in her face, but clearly knowing what Nina had in her hands. Nina gently parted the head's legs and gently slid the dildo up Mrs Green's wet vagina.

"Oooohhhhohohohoh!" moaned the head. She liked it! Nina thrust the toy rhymetically back and forth, while Miss Pye held the bucket of gunge in front of Mrs Green's face, just waiting for the instruction from Nina. What a kinky so and so this headmistress was, Nina thought! No way would she ever see her as an imposing authoritarian again.

"Oh, oh god, oh yes! Yes!" shrieked Mrs Green, as Nina saw her body tense up.

"Right, gunge her!" Nina yelled. Miss Pye did what she had been waiting for and chucked half the bucket into Mrs Green's face, emptying the rest of it onto the head, back and bum. Mrs Green yelped silently and drew deep breaths, thoroughly enjoying an amazing messy orgasm.

Nina and Miss Pye untied Mrs Green and climbed up onto the desk with her. The three naked, messy women embraced in a broad, gungy hug. "So, have we converted you, Mrs Green?" asked Miss Pye. "It's sexy as well as funny, isn't it!"

"It sure is, girls!" gasped Mrs Green. "Thanks for the best feeling I've had in years!"

"Well, we'll be doing it every Monday evening for the rest of the year!" said Nina. "Feel free to drop by the Geography Room any time you like!"

"Maybe I will, when you least expect it!" said Mrs Green, wiping her face and raising an eyebrow deviously. "After all, I can't just leave you two to it without instilling a bit of discipline into things now and again!"

The three of them cleaned up, which was much less fun than making the mess to start with, but Nina felt a warm glow inside all the while, knowing that college was no longer about exams, textbooks and keeping quiet, but red-hot lesbian WAM with two stunning older women.
