The final week of the term started with a mini-heatwave, resulting in large air conditioning units having to be set up in the sports hall to try and keep it at a comfortable temperature whilst exams were going on.

I had to oversee a few exams during the week, but on Thursday I was back in my classroom, completing end-of-year reports during a rare free period when I heard a soft knock at the door.

I turned my head and saw the beautiful smiling face of Abi through the tiny window.

She opened the door, walked in, closed it, and then locked it behind her, then stuck a piece of paper over the window, covering the small piece of glass.

"Hello you," she said, her hips swaying slightly as she approached me.

She looked amazing. Her hair was styled in two French plaits, falling down her slim, athletic body, the top button of her tight blouse was undone, her sleeves rolled up and her tie slightly loosened. Her purple plaid skirt was well above the knee, and her black socks were pulled right up over the knee, perfect.

Abi sat down on my desk, and crossed her beautiful elegant legs, resting her heels on the arm of my chair.

"Did you bring it?" she asked excitedly.

"Of course I did," I replied and reached under my desk for the small lunch bag I'd stashed in the staffroom fridge all day.

I opened it and took out the small champagne bottle and two glasses.

She giggled with glee and clapped her hands together as I set the glasses down, and started to tear off the gold foil wrapper from around the top of the bottle.

I popped the cork as quietly as I could, though there was still a muffled sound, and then filled both glasses.

We each picked up a glass, "To the future," I toasted her, looking directly into her eyes.

She smiled and looked down shyly, then brought her eyes back to mine, "To the future," she repeated and we clinked the glasses together.

The champagne was good, deliciously cold on such a warm day and to be drinking it in my classroom, let alone with Abi was thrilling.

Suddenly, perhaps emboldened by the alcohol, Abi said, "Do you remember when you said you fantasized about fucking me on your desk... Well...I'm on your desk, right now...aren't I?" a cheeky smile spread across her face.

I put my glass down on the desk, stood up, and took hold of her legs, opening them and stepping between them. I took Abi's glass from her and put it down next to mine. I held her face in my hand, leaned into her, and started to kiss her.

Abi wrapped her legs around my hips and her arms around my neck, pulling me closer and returning the kiss.

I could feel the heat between us rising and then Abi's hands started to unbutton my shirt. She broke off from the kiss, our foreheads rested against each other and we looked into each other's eyes.

"You know, it's so hot in here," she said and started to unbutton her blouse.

I finished unbuttoning my shirt and threw my tie to the ground, then helped to unbutton Abi's blouse and eased it off her shoulders. I kissed her shoulder delicately, moving along her collarbone and to her neck as she leaned her head back.

"Oh fuck Abi I want you so bad," I whispered into her ear.

I felt her hand reaching for my cock which was already hard and straining to be free of my boxers and trousers.

She undid my flies, reached in, pulled my cock out, and started to jerk me off gently. I pulled her off the desk and reached under her mini skirt, pulling at her panties, sliding them over her ass cheeks, and let them fall to the floor.

"I don't know why I wear underwear when you are around," she said with a smile as we kissed again passionately.

She raised her leg and I slid my hand up her thigh, edging closer to her most sensitive area.

Abi gasped as my fingertips grazed her labia, then she bit my lip as my fingers slid inside her pussy.

"Oh my God, you're not wasting any time are you?" she asked her voice faltering slightly as my fingers explored her moistening pussy.

Abi started to jerk my cock faster, closed her eyes, and kissed me again.

"Oh Sir, that's so good, keep doing that," she whispered, as my fingers explored, my thumb grazing her clit and index finger curling up just inside her pussy.

My fingers were now drenched in her juices, and my cock was leaking pre-cum all over Abi's hand, as I helped her back up on to desk.

I broke off from our kiss and knelt down, burying my head between her legs and feasting on the puffy lips of her labia and her swollen clit.

"Holy fuck," whispered Abi as my tongue danced across her soaking wet pleasure zone.

I looked up and watched Abi, her eyes on me. She reached behind her back and unfastened her bra, slowly removing it to expose her breasts, never taking her eyes off me. I pumped my cock hard as I looked at her as she started to caress her breasts and squeeze her nipples.

She reached for her champagne glass and downed it, put it back down again, then rested back on her elbows as I continued to gorge on her clit and jerk myself off.

I felt a sudden need to be inside her, I stood up and pulled her up upright by her tie hanging between her breasts and sucked on her nipples greedily before kissing her again.

My cock rubbed against her slick labia and clit and I felt Abi's hand guiding me in, the tip slowly disappearing inside her red hot core. I pushed against her and it slid in as we both gasped at the intense feeling.

"Ooooh Sir," she moaned.

I held myself deep inside her, trying not to cum as her tight pussy squeezed my cock.

The feeling passed and I started to slide in and out of her pussy slowly, drawing my cock all the way out and then rubbing the tip on her clit, before pushing it all the way back in until the tip of my cock hit Abis's cervix.

"Fuck, I'm getting close already," I whispered to Abi as I continued to fuck her.

"Let me suck your cock, I want to taste myself," said Abi.

I pulled my cock out of her and sat down on my chair, undid my trousers, and pulled them down.

Abi climbed off the desk and knelt down on my discarded clothes.

She pushed her plaits behind her back, took hold of my cock, and gently stroked it, then started to lick my balls before running her tongue up the underside of my cock.

I sat back in my chair and watched Abi continue to suck me, she ran her left hand over her bare breasts, cupping them and then squeezing her nipples before her hand plunged underneath her miniskirt and I heard her fingering her wet pussy.

Abi bobbed her head up and down in my groin, her right hand squeezing my cock, her tongue and mouth covering every inch of it.

She then deep-throated me, my toes curled and my hips rose up as my cock hit the back of her throat.

"Oh fuck Abi you're gonna make me cum," I gasped as I watched her looking up at me through watering eyes, my cock buried in her throat.

She rose back up, strings of saliva like a spider's web stretching from my cock into her mouth.

Abi spat on my cock and devoured it again, holding on to my thighs as she forces it to the back of her throat again.

My head snapped back as I tried not to blow my load just yet. I felt her slide off my cock again and looked down at her again.

I took hold of her tie and pulled her to her feet, turned her around, and bent her over the desk.

"Oh yeah," she whispered, "Fuck me on your desk, Sir".

Abi spread her legs slightly and I bent at the knees, held my cock and directed it to her swollen labia, and rubbed it on the wetness, teasing her.

"Fuck me now," begged Abi.

I lifted her miniskirt to expose her pert ass, then pushed my cock into her roughly and thrusted forward, causing her to gasp as my cock stretched her tight pussy.

I started to thrust in and out, holding onto her hips, my thighs slapping on her bare ass cheeks, the desk creaking with the sound echoing in the empty classroom.

She reached around with her arm and pulled my head towards her, turning it so we could kiss.

I slowed down to delay my orgasm, firmly but slowly sliding my cock in and out of her, my right hand groping at her bare breasts.

"Oh fuck I'm gonna cum," I whispered in Abi's ear breaking off the kiss.

"Cum inside me Sir," whispered Abi, "I wanna feel you cum inside me."

I kissed her passionately, my tongue dancing with hers, my hips thrusting faster and faster, then I came hard, shooting my load deep inside her tight young pussy.

I held her close and kept thrusting before finally stopping, my back dripping with sweat from the effort.

My cock slipped out of Abi, she turned around and we kissed again.

"You are so naughty Sir cumming inside me again," she whispered with a wicked grin on her face.

She looked down and put her fingers between her legs to catch some of the cum dribbling out, then licked it from her fingers, "Mmmmm tasty."

I just stood there open-mouthed. This girl was something else.
