Monday seemed to go on forever for Nina. It was tough to concentrate on her studies with Miss Pye's note not leaving her thoughts. The note, however, had lifted a huge weight off her mind. Much as she had enjoyed getting pied, tickled and gunged on Friday night, she was dreading her next lesson with Miss Pye, as it would be really awkward with just the two of them knowing what went on. Now that the teacher had addressed the matter first and apologised, though, it all just felt like fun. Best of all, Nina was being given the opportunity to exact some revenge!

Finally, 4pm came, and Nina made her way to the Geography Room buzzing with excitement and anticipation. Having looked forward to it all day, she bizarrely become a little apprehensive as she got near to the room. What if the note was fake? Or was it possible that it was a bluff and she would get punished again for having the audacity to confront Miss Pye? She was certainly an unpredictable teacher, after all. Nina decided that she might as well go for it; if she did get punished, it might not be a bad thing if Friday was anything to go by!

Nina stood at the door and peered at Miss Pye. She looked gorgeous. Her blonde curly hair had been let down again and it fell over her shoulders. She was wearing a sexy red dress and long, heeled boots. She was rubbing something off the blackboard when she turned and noticed Nina at the door.

"Ah, Cartwright," she said, "so you got my note?"

"Yes, I did, miss," Nina replied.

"Good! Come in, and close the door behind you."

Nina slinked her way into the room and shut the door. Surprisingly, she was rather nervous, even though she wasn't the one about to be on the receiving end this time. Again, there was just one lone desk in the middle of the room.

Miss Pye leant on the blackboard and crossed her ankles. "I just wanted to say sorry for what I put you through on Friday," she said. "I went way over the line, and I feel terrible."

Nina laughed. "It's alright miss, I thought it was quite a good punishment. I deserved it."

A smile flickered onto Miss Pye's face. "Well, maybe you did just a little bit, but I thought I should let you even the scores. I'll get into position."

Miss Pye headed over to the desk, pulled back the chair and took her seat. She crossed her legs and extended them under the table, then she leant forward and put her arms on the desk. It looked strange, not to mention sexy, seeing a teacher sat at a classroom desk like this, waiting to be disciplined.

Miss Pye pulled at her own hair, straightening a few strands then letting them curl back naturally. "The duct tape is in the draw on the right of my desk," she said. "Feel free to strap me up!"

"I just might do that!" Nina chuckled. She got hold of the tape and pulled off an enormous length. Miss Pye breathed in as her student wrapped the tape several times around her chest. Then, Nina pulled the teacher's soft, manicured hands behind her back and bound them together with the black tape.

"Well, I'm not going anywhere!" said Miss Pye, pretending to struggle to break free. Everything was now set for the revenge pieing of Miss Pye!

Nina put her hands onto Miss Pye's shoulders and teased her. "Oh, how the tables have turned!" she said with a cackle, while the teacher giggled somewhat nervously. Being the pie dealer was as fun and sexy as being the recipient, Nina thought to herself, as she seized the first couple of pies from the cool boxes.

"You would not dare hit me in the face with those pies, Cartwright!" said Miss Pye with pantomime sternness.

"Oh, I just might, you know!" Nina taunted in singsong style.

"I'll make you write 10,000 lines!" Miss Pye spluttered. "I'll get you to clean every desk in this building. I'll.ooooh!"

Her ranting was interrupted as a blackcurrant cream pie crashed down on top of her head. As the runny purple gloop dribbled down, Nina put a hand behind Miss Pye's head and smushed a lovely gungy custard pie all over her face.

"Mmmmpph, ohohohohoh!" groaned Miss Pye as she took the facial. That noise sounded almost like a turned-on moan, thought Nina. Could it be that Miss Pye found all of this arousing too? Was that why she'd messed her up on Friday, and why she was offering to play the victim now?

"You deserved that, miss!" said Nina.
The teacher licked her lips and laughed, "too right I did, Cartwright!" she replied. Nina suddenly realised that, even though she was now the one in control, they were still addressing each other in very formal teacher and pupil terms. This was getting kinkier and kinkier!

"Well, there's plenty more coming your way!" continued Nina. "Starting with a sandwich!"

"Well, I am hungry!" replied the custard-faced teacher. "What type of sandwich?"

"Chocolate cream!" said Nina cheerfully.

"Oh, that sounds strange!" said Miss Pye, before her head was enveloped by a pair of enormous, gooey chocolate pies. Nina smeared the filling all over the teacher's hair and face, punishing her good and proper!

"Now, what was that other thing you did to me to teach me a lesson?" Nina said ponderously. "Oh yes, that's right, you tickled my feet, didn't you?"

"Now don't you dare mess with my feet, Cartwright! I had a pedicure last night," the teacher pretended to protest.

"I'm sorry, miss," Nina replied as she lifted Miss Pye's legs onto the desk, "but I'm afraid you don't have a say in the matter. I'll decide how much punishment is enough for you." She had no idea where she was getting this assertiveness from, but it was great fun playing this role.
Nina undid the zips on both Miss Pye's boots and slipped them off simultaneously. Miss Pye wasn't wearing socks, so her feet were now bare. They were soft, smooth and just waiting to be tickled. Nina applied another length of duct tape to the ankles and dug her wriggling fingers underneath the teacher's toes.

"Ohoh, haha, aahhhahaha, heeheehee, oh my god stop hahahaha," said Miss Pye as she fidgeted with mirth. She was a very ticklish lady. Nina ran her fingers down the soles and heels of her victim, increasing the anguished chuckles.

"Right, more pies in the face for you!" barked Nina.

"But.mmpphhh!" Miss Pye protested, before copping a facefull of cream pie. Nina then gently tugged at the teacher's hair to get her to look up, and nailed her with a banana cream pie from above. Miss Pye stuck her tongue out and let the filling fall off her chin and down the inside of her dress.

Nina then held a pie in front of Miss Pye, "dunk your face into it!" she ordered.

"Why should I?" snapped Miss Pye.

"Because if you don't, I'm gonna smash you with it anyway!" Nina laughed. "And tickle your feet!"

Miss Pye sighed, bent her neck back, then slammed her face obediently into the green pie, sportingly nuzzling it right in. A few seconds later, she lifted her head up, her face covered in lime goo, and circled her tongue around her lips.

"Mmm tangy!" she said. "Oh no Hahahahahahahaha!"

The tickling had started again. As Nina brushed the fingers of one hand against Miss Pye's quivering feet, she used the other to chuck a coconut cream pie square in the face. The base was like a pancake and it clung to the helpless teacher's face as she giggled, before eventually falling onto her lap.

"Just a couple more pieings, miss, then we'll see what's left from school dinner today," said Nina. She ran at Miss Pye, plastering her hard with a chocolate cream pie.

"You're a natural, Cartwright!" said the teacher, blinking exaggeratedly. "I give you an A+ in pie to the face delivery!"

"Why, thank you, miss," she replied, as she grabbed a clump of the older woman's messy blonde hair and gently pushed a final custard pie into the face, circling it around and wiping it into her hair.

That was the end of the pies, but there was still a bucketful of something to treat Miss Pye to. Nina lifted the lid expecting to see rice pudding like on Friday night, but it wasn't it was something thick, sloppy and pink.

"Ha ha, strawberry mousse?" Nina chuckled. "I like your style."

Miss Pye laughed, still tied up, splattered with pies and with her bare feet resting on the table. Nina was getting positively wet between the legs with the thought of what she was about to do.

She stood above Miss Pye and sighed, as though sad to gunge her. Then she tipped the bucket up and slowly emptied the slop onto the teacher's head.

"Oh, Cartwright!" she groaned as she got covered. She looked up and took it in the face for a few seconds, gurgling as the mousse went into her mouth. The texture was thick, but runny. Nina then deliberately aimed her pouring down the front of Miss Pye's top, dousing her cleavage with the pudding. When only about a quarter of the bucket was left, she threw the remainder into her victim's face.

"Well, how was that?" Nina laughed, as she untied the teacher's hands. "Wanna call it a truce?"

Miss Pye didn't answer, and was just gasping and moaning sexily. It was then that Nina noticed that Miss Pye had a hand up her own skirt and was moving it back and forth.

"Miss Pye, are youpleasuring yourself?" Nina asked. Suddenly, she could see the embarrassment sweep over the teacher. She pulled her hand away and bowed her head.

"I'm so sorry, Cartwright!" said the ashamed woman. "I'm such a kinky little slut! I shouldn't have dragged you into all this."

Nina was quiet for a few seconds, but then knew what to say. "It's alright, I thought maybe you might like a bit of help?"

Nina untied Miss Pye fully and whispered "I bet you've got a great body, why don't you get naked for me?"

Miss Pye was now clearly relaxed, and stripping naked in front on an 18-year-old student now obviously felt right to her. She pulled her dress over her head and allowed Nina to enjoy the sight of her in her underwear. Then, off came the bra as she bared two wonderfully rounded breasts, and the knickers to reveal her blonde, soaking wet cunt."

"You're one hot teacher!" Nina said. "Lie on your back in the gunge and let me lick you out!"

"Why should I get all the fun?" replied Miss Pye as she lowered herself into the pool of mousse and pie filling all over the floor. "Get that uniform off and we'll 69!"

Nina eagerly ripped off her blouse, skirt, shoes, socks, bra and knickers and dived onto Miss Pye's pussy. As she kissed and licked her clit, she felt the teacher pull on her legs as her own cunt came closer to Miss Pye's mouth. A soft, slobbery tongue delicately stimulated her clitoris.
The feeling was fantastic and Nina moaned deeply as she kept licking Miss Pye out. She started rolling about in all the gunge with her, getting covered in it herself. She grabbed handfuls of it and dumped it over Miss Pye's vagina, then enjoyed licking it all off as the teacher did the same to her.

"Ohhhoohhoh I'm coming, Cartwright!" screamed Miss Pye as she orgasmed forcefully.

"Fuck yeeeeaaahhh! Me too, miss!" said Nina, also unleashing her pussy juice.
Breathless, the two women claimed off each other and sat side by side, naked, in a messy embrace.

"My god, I've been missing out!" Nina panted. "Sex and desserts are the hottest combo out there!"

"I'm so pleased you enjoyed it!" Miss Pye smiled. "It could all have gone so wrong, but you've made my dreams come true!" She kissed Nina on the cheek. Nina realised this could be a pretty special relationship with her teacher.

Just then, somebody started yanking at the handle of the door, which made them both jump.

"It's OK, I've locked it," said Nina, but then they heard the turning of a key and the click of the door unlocking.

"Shit! The master key!" Miss Pye whispered frantically. "Somebody must have it!"

The girls shot to their feet and looked desperately for somewhere to hide, but it was too late the door was opening and the imposing figure of Mrs. Green, the headmistress, was stood in front of them, clothed in a traditional mortar board hat and cloak. Her mouth was agape in horror at what she was seeing.

"Miss Pye? Cartwright?" she cried in disbelief as she slammed the door shut. "Explain yourselves at once!"

That nervousness and dread had come straight back to Nina in an instant. She tried hopelessly to shield her nakedness by crossing her left arm across both her breasts and cupping her right hand over her vagina, but it was a waste of time as the head had seen all she needed to see.

It was completely the wrong time for Nina to be thinking like this, but Mrs. Green was fit too, in a milfy sort of way. She was probably in her forties, about 5'2, with thick glasses, neatly tied black hair and rounded, prominent breasts.

"Er Nina and I just decided to have a pie fight," said Miss Pye. What else could she say?

"In the nude?" the head fumed, "this is a prestigious college, not some theatre of sexual perversion!"

"Mrs. Green, this was all my idea," said Miss Pye. "Please leave Nina out of this, I accept full responsibility."

"SILENCE!" the head yelled. "I will not have the proud name of Wamsthorpe besmirched by this sort of debauchery. Miss Pye, your contract here is terminated with immediate effect! And Cartwright, you are expelled!"

"Is there nothing we can do to make you reconsider?" Miss Pye pleaded.

"Certainly not!" snapped Mrs. Green.

"Nothing at all?" asked Nina.

"Nothing!" the head confirmed.

"Well, if that's the case." said Miss Pye, as she opened another of the red boxes and produced a custard pie, "take that!"

She threw the pie overarm. As it sped towards Mrs. Green, she put her hands in front of her chest and closed her eyes. The pie hit her straight in her bespectacled face, knocked off her mortar board and splattered all over the blackboard.

"Ooooohgosh!" squealed Mrs. Green as she dropped to her knees in slapstick fashion. Suddenly, the mood had changed and Nina had gone from ashamed and dejected to excited once more. As soon as the mess started flowing, nothing else seemed of any significance.

Nina picked up a chocolate cream pie herself and closed in on the headmistress. She pulled off the glasses, leaving two clean circles around her eyes on her otherwise custard-covered face.

"And take this too!" said Nina, smushing the pie into Mrs. Green's face and grinding chocolate cream and crust into her features and hair. Mrs. Green gasped and licked her lips. If she wasn't enjoying being pied, she wasn't exactly offering much resistance.

"Shall we sandwich her!" Miss Pye asked Nina with a wink.

"I think so," replied Nina. Mrs. Green was still down on her knees, clearing her eyes and puffing and panting. The two women smashed the sides of her head with gloopy whipped cream pies.

"Any strawberry mousse left, Miss Pye?" asked Nina sweetly.

"Should be, Cartwright!" replied the teacher. "Check the box behind you!"

There was indeed a full bucket of pink slime in the coolbox. It was freezing cold, and Nina started to pour it over Mrs. Green's head. She gave a shrill, almost voiceless cry and looked up, totally voluntarily, to take most of the mousse in the face. As the bucket was running out, Miss Pye filled up the mortar board hat with mousse and slammed it back onto Mrs. Green's head to complete the messy humiliation.

"Well, we might as well go out in style!" laughed Miss Pye, slapping a high five with Nina. The headmistress was still on her knees looking shellshocked. Then she started to giggle, and it grew louder, eventually turning into a boisterous cackle at her own misfortune.

"See? It's funny!" said Nina. "Miss Pye and I are just having harmless fun together. Is that so bad?"

The head cleared her eyes and looked up at her two tormentors. "Well, maybe you've won me over, ladies!" she said. "Hand me a towel and let me use the gym showers first, and I'll let this go."

"So I can keep my job?" asked Miss Pye, handing her a towel.

"You can, Miss Pye. You're too good a teacher to lose over a silly matter like this."

"And can I stay in the college?" asked Nina.

"Of course you can, Cartwright," said Mrs. Green softly.

"And can Nina and I use this room every Monday evening to mess each other up?" Miss Pye quizzed, pushing her luck a bit.

"Er well, I don't see why not," said the head reluctantly. "But I know nothing of it, OK?"

"Oh thank you, miss!" said Nina to the headmistress.

"That's OK, ladies. Now, if you'll excuse me, I'm going to make an inconspicuous dash to the showers."

The head left the room and Nina and Miss Pye looked at each other, delighted with how everything had turned out.

"That's the power of pies!" said Miss Pye.

Still naked, Nina and Miss Pye put their arms around each other's messybodies and kissed passionately on the lips.
