Entering Mr. Barton's office, I knew exactly why he had summoned me. I had fallen behind with my studies.

As my heels clicked across the floor, I felt his bright green eyes following me. Reaching his large desk, he smiled and nodded toward the empty red leather cushioned chair. Sitting down, I felt my knee-length skirt rise up my thighs, presenting my teacher with more than I had intended.

This close-up view afforded me another opportunity to appraise the married, thirty-something, tall handsome man, with dark salt and pepper hair.

For the past two terms I had sat in his class, ignoring the fanciful rumours that inevitably associate themselves with popular teachers, and their female students.

"Well, Catherine, here we are again," he said, his tone suggesting that this meeting came as no surprise to him.

I proffered a weak smile.

Sir continued, "You are capable of passing this course, your earlier promise and application proved that. But your last three pieces of work were below the expected standard.

"Last time we met you promised to turn things around, and explained that several external problems were interfering with your ability to deliver."

As my tutor spoke, his eyes flicked across my thighs and briefly alighted on my ample breasts, their shape accentuated by my tight blouse.

"What am I to do with you, Catherine? At the moment you are going to fail spectacularly and miss out on a much-needed bursary."

As he finished speaking his eyes took a more deliberate peek at my body. I shifted uncomfortably. My eyes met his as they levelled again with mine, and there was a telling recognition on his face that I had noted his voyeuristic lapse.

I began to explain, "Sir."

At which point he immediately interrupted, "Call me Stu, after all, it isn't as if we are strangers."

I nodded my assent. "Sir, I mean Stu, things are very difficult back home. My parents are divorcing and I now don’t get much money. I have taken bar work in the evenings to make ends meet, and subsequently, my studies have suffered."

His eyes again fell to my thighs, but he quickly recovered and said, "I do sympathise with you, Catherine."

Which was my turn to interrupt, "Call me Cat, Stu; everyone does."

"Yes Cat, I like that, I have always had a liking for pussies," he grinned pleased with his cheeky inference. I returned a knowing smile, at which his eyes widened appreciatively.
Stu made a steeple with his hands as he pondered his next words. My hands fidgeted nervously in my lap. I stared pleadingly, biting my lower lip. I desperately needed that bursary.

Again, his eyes flitted over my body but this time he didn’t attempt to disguise his interest.

Taking a breath he said, "Cat, you are a beautiful young woman, and without a doubt talented academically." He smiled as if enjoying my vulnerability. "I wonder Cat, do you have other talents that might rescue you from this unfortunate predicament?"

I smiled quizzically at Stu's suggestion, but, before I could respond, he continued, "How badly do you want this Cat? I really want to help you, but my hands are tied academically speaking. Unless we can come to some arrangement. You know what I mean; I help you, and you do something for me."

Although a little shocked by the suggestion, I couldn't stop myself blurting out, "I will do anything!"

At that moment I noticed Stu smile, and his eyebrows rise briefly.

Twirling a pencil between his fingers his emerald eyes observed me. I could tell that he was carefully considering his next statement, as if everything hinged on it. But I knew he had me where he wanted me.

"I am prepared to help you, Cat, but it must be our secret. The grade you wish to achieve, and the subsequent bursary size, will very much come down to your willingness and obedience."

l nodded dumbly, feeling as if I had unwittingly stumbled into a game. I realised that the rumours about 'that cute Mr. Barton' being a player, must be true after all.

I felt my cheeks blush, and I crossed my legs, which Stu duly observed.
His voice woke me from my thoughts, "A favour for a favour Cat, that is all this will be. As I alluded to earlier, you really are an attractive young woman. Your obvious charms would certainly help you pass this course."

As Sir's words struck home, my mind was busily imagining what lay ahead.

Grinning, Sir brusquely said, "Meet me after school, Cat. I will be in my photo lab where I run extracurricular activities. No one will be there but us. You can begin working on a special assignment I have, for gifted students such as you."

Standing to leave, I tugged the hem of my skirt lower and looked him in the eyes, nervously asking, "What is it you want me to do for you?"

Stu came around the desk, placed an arm around my waist, and walked me toward the door, replying, "A couple of photographs for my private collection, and afterward, see what develops." He laughed as he said this, in this age of digital photography his in-joke was lost on me. He gently patted my tightly packed bottom whispering, "Not a word to anyone."

Later that day I entered the photography classroom, my heart pounding nervously in my chest. Photographs adorned the walls, everything from portraits, to bowls of fruit, and even wildlife.

Stu startled me; I hadn't noticed him standing at the door to the lab. "Come through," he said, beckoning with his hand. I followed him into a room containing all kinds of photographic aids.

He surveyed the classroom checking no one else was around, and closed the door. My heart beat a little faster now that we were alone.

Stu looked at me smiling. "No one will disturb us, Cat, once we move into there."

I followed his gaze toward another door. "Why, what's in there?" I asked nervously.

"It's my darkroom, where photos and negative film is developed. I still teach students the old ways."

I noticed a sign on the door which read, 'When Red Light Is On Keep Out!' Above the darkroom door was a red lightbulb, currently unlit.

"I take it that you are happy to continue with our arrangement, Cat?"

I returned an uncertain smile, replying, "I don't know yet. But I'm here and really need to pass this course."

"Well Cat, depending on how far you want to go, will boost your end of year mark."

I looked questioningly at him.

"You need at least a C to qualify for a bursary. For that you could pose for a few photos and help me get off. A blow job would reward you with a B. A straight-A speaks for itself, does it not?"

Hearing Sir laying it on the line sent me a little dizzy. The realisation of the deal I was being offered hit home.

Stu smiled coolly as he watched my reaction. "I assume with your figure you are sexually active, Cat?"

"B b boyfriends, yes," I stammered, unprepared for the question.

"Quite the little slut, are you?"

"No Sir!" I replied resolutely.

"I think I will be the judge of that, now be a good slut and take off your clothes."

"Slut?" I questioned shocked. Things were accelerating quickly, and I stood unmoving.

Stu picked up a digital camera from a shelf and said, "Come on slut, the sooner we get done the quicker your marks improve."

I began to undress awkwardly; I pulled the tight top over my head, as my bra clad C cups jutted into view. I threw a glance at Sir whose eyes had widened appreciatively, taking in every detail of my black semi-transparent bra.

Next, I unfastened my tight skirt, struggling ungainly to work it down my shapely hips. My matching panties rolled down with the skirt, the gusset eventually springing free like an afterthought.

Stepping out of the clothing, I looked at my teacher, who was now visibly nursing a sizeable bulge in his Chino's.

"Lovely slut, I do prefer a clean-shaven pussy, now the bra," he ordered.
Seeing Stu's obvious excitement, I began to relax. Reaching behind to unclasp my bra, I locked eyes with his. I very slowly allowed my straps to fall loose, my fingers spreading teasingly over the soft cups delaying the big reveal.

Stu licked his lips, his eyes burning into mine, silently imploring me to let him see my beauties. Finally, I let the bra fall, my large breasts spilling out, revealing my firm dark-tipped nipples.

Stu's jaw hung open, as his left hand slid unconsciously to his straining erection. I watched transfixed as he gripped himself through the fabric, revealing himself to be a very well-endowed man.

My pulse raced and I felt a pang of arousal.

Recovering his demeanour, he let his excited penis loose and barked, "Stand still slut, let me capture this."

He hurriedly raised the small digital camera and repeatedly pressed the take button. I noticed that his hands were shaking. "Turn around slut," he directed.

I slowly turned my back to him, hearing him gasp, "Oh fuck!" as I presented my large round bottom.

The camera fired off more shots. I turned to look at Stu who was already placing the camera back on the shelf.

Placing a warm hand on the small of my back, he urged me toward the darkroom. "In there slut, it's your decision time."

Opening the door, Stu reached up and pulled the corded toggle switch, which bathed the room crimson. In that same instant, I felt his hardness brush against my naked rump making my nipples firm and pussy tingle.

The darkroom was tiny, the eerie red light giving everything a surreal glow. My eyes adjusted and I could see chemical bottles, trays, a small basin, and behind me a cushioned stool.

I turned to face Stu as the door to the tiny room closed, snuffing out the last natural light.

My mind raced and my heart thudded, as I found myself becoming more excited. I could suddenly smell my sweet arousal, and wondered if Stu could too.

Stu promptly unfastened his shirt to reveal neat hairy pecs and a flat stomach. His thumbs hooked into the waistband of his Chino's, as I stared keenly through the crimson hue. Wasting no time, he dragged his Chino's and boxers down over his straining manhood, which sprang free.

Pointing at me was the biggest cock I had ever seen, with its impressive ball-sac and neat hairy crotch. Huge and menacing, it danced as if celebrating its freedom. Now it was my jaw which hung open, as I croaked, "Oh fuck!"

Though less than two metres between us, I could already feel its heat. Stu broke the spell as he ordered, "Sit slut!"

Backing myself onto the stool, my soaked pussy kissed and smeared the vinyl covering.

I checked my posture, noting how the rouge light accentuated the shape of my plump mound, deep cleavage, and the darkness of my saucer-like areolas; my long thick nipples made to look more prominent than ever!

Stu moved toward me, his erection proud, the strange light-enhancing his thick veiny shaft, and coating his crowning glossy glans a deep maroon colour.

My eyes pulled away from his gorgeous cock when Stu asked, "Slut, have you decided which grade you wish to achieve, do I need to repeat your options?"

I looked at his rampant cock, and heard myself croak, "I want a C, Sir."

His cock visibly jumped, as I confirmed my choice. Stu slowly began stroking his straining member, his foreskin drawn back exposing its large glistening head. It was as beautiful as it was impressive.

My hand reached toward his hardness, eager to touch it and play my part. Stu anticipated the move and slapped my hand aside saying sharply, "No slut, you don't get to touch me, you must touch yourself."

My heart sank, I so wanted to feel his flagrant erection.

Stu rubbed his shaft steadily, working the foreskin back and forth. "Touch yourself, slut," he barked.

Unable to tear my eyes from the salacious activity before me, I settled into the seat and squeezed my breasts with both hands, my erect nipples protruding between my small fingers. It felt thrilling, touching and massaging my firm tits.

Breathlessly, Stu said, "Yes that's it slut, touch yourself."

Smiling I needed no second invitation. I ran my hands over the sides of my breasts, my back arching as I pinched my nipples. I opened my legs a shoulder-width, affording Stu his first sight of my glistening wonderland.

As I ran my fingers over my smooth mound, Stu groaned and moved closer, his hand vigorously stroking his steely cock.

I licked my lips seductively, as I watched his silky foreskin glide effortlessly around his cock’s huge girth. His dark purple knob appearing more threatening, with every downstroke.

Glancing at my mentor's tortured face, I saw his eyes riveted to my wet pussy. My eyes returned to his raging hard-on, my desire to touch it frustratingly irresistible.

I pinched each nipple in turn, as I slid v-shaped fingers around my engorged clit, rubbing my clitoral shaft back and scissoring my sensitive pearl. I was panting heavily. My pungent aroma filling our tiny space.

The sound of our laboured breathing was interrupted, when Stu groaned, "You are such a beautiful and sexy slut. I won't last much longer."

On saying that, he stepped closer, his throbbing cock only inches from my breasts. Fuck I wanted him. Opening my legs wider, my pussy wet with lust, I rubbed my slippery clit faster, closing in on my orgasm.

Stu's engorged shaft pulsed, as he pumped frantically. Precum drooled from his tip. Our moans reached a crescendo.

His hips thrust forward, jerking his foreskin hard back. With eyes ablaze, his body stiffened, and his fist continually slammed the ridge of his pulsing helmet, his climax imminent.

My fingers plundered my throbbing sex, plunging deeply into my velvety cunt, as I strummed wildly at my needy pearl, finally pinching her.

I shook violently as my orgasm hit. My euphoric cries, wide eyes and upturned face, were all it took to trigger Stu's tumultuous climax.

With a climatic grunt, glassy pink cum shot like a bullet from his rearing manhood. The first deluge smacking my nose, mouth, and chin. The essence of chlorine saturated my senses. 

Almost instantaneously, a second scalding rope lashed my wanton breasts. Another powerful spurt followed close behind, drowning my busy fingers and clenching pussy.

I watched delightedly, as his excited cock ejaculated relentlessly, drenching my climax wracked body. 

Finally spent, and in a breathless voice, Stu asked, "Did you enjoy that slut?"

As I sat with my cum spattered body prostrate and heaving, I grinned and pleaded, "Please can I try for a straight-A tomorrow Sir?
