I put my arm down, glowing with pride. I'd correctly answered a question posed by the delectable Dr Cooper, and she had rewarded me with a faint smile—at least I think she did.

There was a nudge from the guy next to me. I turned to face him.

“You do know you called her ‘Miss’, don't you?” he whispered, suppressing a snigger.

I felt my face redden. “No, I didn't do that!” I hissed, trying to keep my voice down.

“Yes, you did! What were you thinking?”

Was he right? Had I? “I can't have done,” I nervously replied, but with growing doubt.

“Yes! You did, you idiot!”

“I heard you as well,” chimed in my neighbour on the other side.

“Shit!” I observed, a little louder than I'd intended.

A silence descended on the lecture theatre. I sensed I was its cause.

“You! In the second row! Stand up!” boomed Dr Cooper.

Nervously, I did so. My legs were quivering.

“What's your name?”

God! What was my name? She'd got me flustered. “Er... it's... erm.. it's Harry Lloyd,” I mumbled.

“Are you here to study, Mr Lloyd, or gossip with your neighbours?”

I looked up, my cheeks burning. “Er... sorry, Dr Cooper,” I replied.

She stared at me. She was twenty years my senior but exceedingly fuckable, although I was yet to fuck anyone, let alone her.

A MILF would be a good description. She was blonde, tall, slim and well-proportioned. She stood for no nonsense, and her withering way with words sent a shiver down my spine. While she was undoubtedly a MILF, another term that sprang into my mind was dominatrix. Her tone of voice and the provocative way she dressed screamed domination—or at least it did when I was wanking, thinking of her.

Did she know what effect she was having on male students? Or was it just on me? Did others notice how often one too many of her buttons was undone to reveal the top edge of her bra? Did they, like me, find themselves focusing on her long, slender legs, hoping for a glimpse of her panties as she crossed and uncrossed her legs while perching on the desk in a short skirt? It had only taken me ten minutes in this lecture to spot that she was wearing black panties with a black bra—last week it had been matching powder blue. Were others seeing what I was seeing? Or was it just me?

“Are you here to waste my time?” she enquired, speaking with her refined upper-class accent which oozed authority.

“No... no, sorry, I'm not...” I muttered, just stopping myself from calling her “Miss” again.

“Then what was I saying before you talked over me?”

Oh, God! What had she been saying?

“Erm... it... it was about high copy numbers in plasmid replication in prokaryotic cells... wasn't it?”

“I've mentioned something else since then. You'd better see me afterwards! We need to have words, Mr Lloyd.”

I felt my penis stirring inside my boxers. I'd lost the ability to speak, except in grunts, so a nod was the best response.

oooOOooo

I stood in front of Dr Cooper. The rest of the class had gone, and she and I were alone in the lecture theatre.

She dropped down from the desk. Her sensual perfume wafted in my direction, and I was aware of a further stirring down below. Do not get an erection and make an utter fool of yourself, I told myself.

“How old are you?” she asked, glaring at me.

“I'm nineteen,” I murmured, feeling overwhelmed by her presence. Only now had I become aware that she was four inches taller than me. I felt insignificant, positioned in front of her, like a worm—I even sensed I was wriggling like a worm. She bore an air of authority which was both intimidating and exciting.

“This is a university, Mr Lloyd. We expect our students to be mature and behave responsibly. Do you understand?”

I nodded and impulsively lowered my eyes, only to realise that another button had come undone on her shirt. My eyes widened, and my willy gave a thump.

“Will you stop staring at my damn chest?!” she screeched, as she scrabbled to do up two buttons.

I flicked my eyes upwards. “Sorry, Miss!” I exclaimed. “Sorry... I... I didn't mean to call you ‘Miss’, Miss—Argh! Sorry!”

She impatiently rolled her eyes and expired loudly. “Come and see me in my office at seven o'clock. And do something about that before you come!” She pointed down at my groin—at the tent pole that was pushing its way forward.

oooOOooo

I spent the rest of the day thinking about her and about the meeting we were due to have that evening. I couldn't get her out of my mind, and I was in a state of permanent semi-arousal, meaning I was having to walk around the campus covering my embarrassment with my rucksack.

“A problem with the straps, Hannah,” I muttered when the prettiest student in my year had asked me why it wasn't on my back.

“They look fine to me,” she'd answered, compounding my shame. She gave me a knowing wink, causing me to blush.

oooOOooo

I skipped the final lecture of the day and returned to my flat, taking Dr Cooper's advice to deal with my arousal.

As I stroked my boner, I was thinking about nothing but her. I couldn't get it out of my head how attractive she was... and how authoritarian she sounded. I'd watched some videos where dominant females of Dr Cooper's age put young men like me over their knees and spanked them. In those videos, the women were sometimes sexily dressed in black undies, the same colour as Dr Cooper was wearing that day. Was it too much to hope that she would put me over her knees that evening, stripped down to her bra and panties?

I paused my stroking. Pull yourself together, Harry! She's an eminent scientist at a prestigious university. There's no way that she spends her evenings administering corporal punishment to wayward students. But that image remained with me as I resumed my rubbing. Seconds later, I ejaculated, sending a powerful stream of seminal fluid into the bunched-up tissues in my hand.

Reality returned as I descended from my climax. She was going to tell me off that evening... nothing more, nothing less.

oooOOooo

At 7 PM on the dot, I tapped on the door of her office. “Come!” she beckoned.

She was sitting behind her desk, her legs out of view, and her blouse buttoned up. I looked her in the eyes, determined not to let my gaze drift downwards but knowing that with her shirt being fully buttoned, the fabric would be stretched tightly over her breasts. And they were divine boobs—there was no question about it because I had spent a few lectures fixated on them.

“Well?” she asked.

I stood dumbfounded, unsure what she was asking. She stared at me, and had no intention of clarifying her enquiry.

“I've... I've dealt with it.”

“What?” she squealed. “What are you talking about?” The bewildered expression on her face told me that I'd misinterpreted the question.

I felt myself redden. “Sorry... that's not what you were asking, was it?” Could I possibly make a bigger fool of myself?

Her eyes now bore a glint of understanding, and she slightly nodded her head. “Yes! It needed dealing with. But what do you have to say about your behaviour in my lecture this morning?”

“I'm very sorry, Miss! Sorry! I didn't mean that... I mean, I'm sorry about my behaviour, but I didn't intend to call you ‘Miss’.”

“At least that term shows respect, while talking in my class does not. Understood?”

“Erm... yes... Dr Cooper.”

She nodded, apparently satisfied that I was showing sufficient reverence. “Go and stand facing the wall, Mr Lloyd,” she announced, pointing at a blank area to my right.

“Sorry?” Had I heard right?

“You heard me, Mr Lloyd, so I'm not going to repeat myself.”

“But—”

“Mr Lloyd!”

Is this how domintrixes treat their submissives? Despite my recent relief, I felt my penis thickening and lengthening. Not again, I thought! Get a grip, Harry!

A tent pole was forming. What she wanted me to do was humiliating, but so was standing in front of her with a partial erection. I walked over to the wall and turned around to glance at her, seeking confirmation I was doing what she wanted.

“Put your hands on your head and your nose against the wall. Use the time to think of an appropriate penance for talking during my lecture.”

Feeling mortified but powerless, I did what she required, and I stood motionless, wondering how long she wanted me to remain there. The longer the better, perhaps—I was willing my erection to subside, but the more I thought about it, the stiffer it became.

It seemed like an eternity before she called me, but still the erection persisted. “Mr Lloyd! Come back over here. You may put your arms down.”

I did so, clasping my hands in front of me in a most unnatural pose. My face must have resembled a beetroot as I waited to see what she would say next. I felt beads of perspiration forming across my forehead.

She was still behind her desk, and her eyes were focused on my groin. It was obvious to her what I was covering up.

She peered up, expressionless. “Well?” she asked, for a second time that evening.

What did she want to know this time? I had no idea. “Sorry, but what was the question, Dr Cooper?” I timidly enquired.

With a look of exasperation, she replied, “You have the memory of a gnat, Mr Lloyd. I told you to spend the time facing the wall thinking of an appropriate penance for talking in my class?”

“Oh... Erm?” Did she want to spank me, I wondered. Surely not, but I felt my penis give a jolt, and I pulled my hands closer to my jeans. My penis was throbbing. I could spontaneously ejaculate at any moment.

“Well?” she impatiently repeated.

“Er... a spanking,” I quietly replied, with instant regret. What had I said? What was I thinking? That can't be what she had in mind.

“What? Speak up, Mr Lloyd. I don't have the hearing of a barn owl.”

“Nothing... I said nothing.”

“You said something! Tell me what you said, Mr Lloyd! I'm not prepared to put up with this nonsense.”

“Hmm... I was suggesting a spanking, Dr Cooper,” I ventured. “Sorry... it just came out. I shouldn't have suggested it.”

“Who do you think I am? Your mistress? A lady of the night? A strumpet?”

I shook my head. “No! Sorry... When you said penance, I just thought of a spanking.”

“The first thing that came into your silly little head, I suppose. I was thinking more of a handwritten letter of apology.”

I nodded. “Sorry.”

“I'm not impressed with your inability to control your... er... hormones,” she remarked, looking down again at my groin.

She's a biologist, I thought, so she must know willpower can't control hormones.

She reached into a desk drawer and pulled out something pink and plasticky. “You might wish to put this on and return here tomorrow evening at the same time. Then we might be able to have a sensible conversation without you embarrassing the pair of us.”

She flung the object across the desk, and I caught it before it flew off. I recognised what it was—a chastity cage with a padlock but no key. How the hell did she come to possess such a thing?

“Really?” I asked, unsure what was happening.

“Your decision, Mr Lloyd. We can carry on tonight with you in that state, or we can continue tomorrow.”

oooOOooo

I returned to my flat, the chastity device in my pocket, gripped in my hand. I needed to hold it to confirm it was real and I hadn't been dreaming.

Part of me couldn't believe my luck. But was it good luck or bad luck? The thought of being dominated by the luscious Dr Cooper, giving her control of my orgasms, was arousing, but wearing the cage would make those arousals painful. The cage was a double-edged sword. Common sense said I should not wear it, but my penile brain told me otherwise.

A second wank of the day was called for. I thought that relieving myself would allow sanity to return. Except it didn't. Afterwards, I still felt an urge to slip on the cage.

It fitted, and it was a snug fit. But I still had to push the padlock shut. Was that a sensible thing to do?

I thought about it for a few minutes, wavering one way and then the other. Then, with a firm press, I closed the clasp.

oooOOooo

I spent a difficult night, with my willy desperately trying to expand into a limited space. Twice I had to get up to apply ice. Clearly, what I'd done was stupid, but... but if it pleased Dr Cooper, perhaps it was worth it.

Not surprisingly, I was awake early, before any of my flatmates, so I chose to spend an hour handwriting an obsequious letter of apology to Dr Cooper. This seemed to be what she wanted. Pleased with my letter, I sealed it in an envelope which I slipped into my rucksack. At least that day I could carry the rucksack on my back.

“Oh, you've repaired the straps,” opined Hannah, the pretty student who had teased me the day before. “Don't look any different to me,” she added with a mischievous grin and a playful sparkle in her eyes. She was very fuckable, but she had a reputation for being hard to get. Sure, she was happy to rib me, but did her interest in me extend beyond that? I was too shy to ask, so I could only dream.

I spent the day tent-free, but in some distress. Another visit to Dr Cooper was never far from my thoughts.

oooOOooo

“Come!” Dr Cooper instructed in response to my knocking on her door.

“Good... good evening... Dr Cooper,” I babbled as she stared up at me from behind her desk.

With trembling hands, I passed her the letter. “It's... it's an apology, Dr Cooper,” I stammered.

Picking up a paperknife, she slit the envelope open. She removed the contents and quickly scanned it before looking up at me again.

“Well, it's an apology of sorts, I suppose. Your handwriting is atrocious, and there are a couple of grammatical errors and—”

“Sorry.”

“Do not talk over me, Mr Lloyd. Isn't that exactly why you're here?”

I nodded.

She was quiet for a minute or so, observing me closely. “You were right yesterday...”

“Pardon?”

“You were right, Mr Lloyd. A spanking is called for. Don't you agree? It might teach you a proper lesson.”

I winced as my penis struggled to expand into its tube. Had I heard right? She was going to spank me!

“Should I spank you, Mr Lloyd? Is that a fitting punishment for immature behaviour?”

I nodded vigorously, my mouth suddenly too dry to speak.

She stood up and moved to the door, locking it and pulling down the blind above the glazing in the door. She then pulled down the blind over the main window. “What are you waiting for, Mr Lloyd? You should be undressed by now.”

My penis continued its desperate bid to thicken and lengthen, but its efforts continued to be thwarted. With trepidation, I began to remove my clothes, suddenly feeling self-conscious as she remained fully dressed, staring at me.

“Quickly,” she urged. “I don't have all night.”

I was now down to my boxers and, with a final glance into her eyes, I lowered them and stepped out of them. Instinctively, I placed my hands over my cage. The expression on her face changed from neutral to irritated. I guessed that Dr Cooper wanted my hands to be moved and, without being told, I placed them on the top of my head.

She pulled out a large hard-backed chair from the side of her office and positioned it in the centre of the room.

“Come on,” she ordered, sitting down and patting her thighs. She had pulled up her short skirt, revealing more of her legs, which were bare and bronzed from the summer sun. They were weirdly inviting, and I lowered myself down. I felt the sensual warmth of her flesh, and my willy attempted another protest.

Dr Cooper tenderly caressed my buttocks, and I thought it strange that someone so authoritarian would display such gentleness. But then the spanking began as she rhythmically slapped alternate sides. The first minute or so was quite pleasurable, but any sense of eroticism quickly wore off as the punishment progressed.

“This is what you deserve, Mr Lloyd. Don't you agree?”

“Yes... Dr Cooper,” I spluttered, as my bottom heated up under the relentless pounding. My penis, only minutes ago a willing participant, had beat a hasty retreat. The spanking seemed to go on forever.

“Have you anything to say to me?” she eventually asked.

“Yes!! Please stop!” I breathlessly replied.

“Isn't there something else you need to say first, Mr Lloyd?” she enquired, as she continued my punishment.

My brain was spinning. What on earth did she expect me to say? Then the penny dropped. “Yes! I'm really sorry for talking in your lecture yesterday.”

“Good boy!” And instantly she ceased the pummeling. “Up you get. No rubbing!”

With a red face and a red bottom, I eased myself off her lap. I gazed at her, and I could see her face was flushed, and she looked excited.

Exertion? Possibly, but despite my sexual inexperience, I sensed it was something else.

“Now I've put in the time and effort to correct you, I'm wondering if you would do something for me?” she asked, looking up at me.

I nodded, but was clueless as to what she wanted.

“Get down on your knees in front of me.”

I did, and I found myself staring straight up her skirt. I could see a white triangle, which contrasted sharply with the dark blue of her skirt. My willy didn't know whether it was coming or going as it once more attempted to swell, causing considerable discomfort.

She eased herself up from the chair, pulled her skirt even further up and slipped down her silk panties. With a finger on either side, she parted her vulva, and I was staring at her glistening pussy. It was framed by crisply trimmed light brown hair.

“Is this your first time, Mr Lloyd?”

“Yes,” I croaked.

“Everyone has to start somewhere,” she remarked, in a surprisingly sympathetic tone. “I understand you did a module last term on human anatomy, which might help.”

Tentatively, I moved closer to her and was rewarded by the adorable scent of pheromones tantalising my nasal membranes. My willy struggled inside its prison, but I was determined to plough on.

“Lips and tongue—no teeth!” she advised.

Using my tongue, I explored her vulva, tasting her sweet nectar and quickly discovering her labia minora. As gently as I could, I sucked one with my lips, and she responded with a little wriggle. I continued my ventures, moving around, sensing the topography. At the top, I found a small bud which had to be her clitoris. It was firm and engorged, and just the subtlest touch of my tongue caused her to moan.

Moving down, I discovered her vaginal opening and carefully pushed my tongue inside, making her squirm.

“Good boy...” she remarked. “You're... doing well. Keep going.”

I continued my servicing, moving around from vagina to labia to clit to vagina, all the while aware of her growing arousal. Increasing amounts of her secretions kept my mouth lubricated. Her whimpers grew louder, giving me the confidence to continue.

“Ooo-OOO-ooh!” she shrieked several times. “Keep... keep going!”

She began wriggling, moving her hips and grabbing my hair to grind my face into her pussy. Her vocalisations rose by the second, and then, suddenly, she screamed a string of expletives that appeared totally out of character. Her whole body shook and arched as she bucked up and down in the chair. It went on for ages, and all the time my mouth remained in contact—no way was she letting go.

Then it was all over. Her body went limp, and she released her grip on me. I pulled back and waited for her to say something, but she had lost the power of speech. Her eyes were tightly shut as she processed the ride she had taken.

It was several minutes before her eyes popped open, and a smile crossed her face. “Well... done, Mr Lloyd,” she stated. “I... I can't believe how good you were—for a beginner,” she breathlessly added. “With more practice... you... will more than please... any woman.”

I returned her smile, wallowing in her praise.

A couple of minutes of silence followed, and then she straightened her back, saying, “I'm guessing you want the key to your cage? I imagine there's something that needs attending to.”

There was! She passed me the key, and I unlocked the padlock and painfully yanked off the device, which was reluctant to release my swollen organ.

I began to fondle myself. “Let me,” she softly commented. “Lie on your back.”

She took over from me, gently holding my penis and repeatedly drawing her fingers up and down the rigid shaft, stopping for a few moments at the top to tease the sensitive nerve endings in my glans.

For several minutes she continued her manipulations, easing off each time I came close to cumming.

“Please, Dr Cooper,” I urged. “Let me shoot.”

“Patience, Mr Lloyd,” she softly replied, before bending down and taking my hard-on into her mouth.

“Oh, God,” I shrieked. Never had I experienced anything like that. It was heavenly, and the sensations she was creating with her lips and tongue were unbelievable.

Still she played with me, edging me slowly to an inevitable eruption. Without warning, she increased the pace, and I reached the point of no return, exploding into her mouth.

It took me a while to catch my breath. “Thank you,” I said. “You're... you're no longer angry with me?”

She smiled, and I could see she was still swallowing, trying to remove the last traces of my jism from her mouth. “How could I remain angry with you, given your oral talents, Mr Lloyd,” she eventually remarked. “But in future do try not to talk over me in lectures.”

I stood up and tried to give her back the cage. “You keep it, Mr Lloyd, with the key. It might spare you some embarrassment on campus. Hmm?”

“Understood... But can we... can we do this again, sometime, Dr Cooper?”

“No, Mr Lloyd. Consider it a one-off—a practical lesson in biology. You have to find someone your own age. Seek out that pretty girl I noticed you talking to yesterday. I'm sure she would welcome your skills. I can't imagine any of the cave dwellers in your year would put her needs first, but that's what girls want, Mr Lloyd.”

“Er... you mean Hannah... okay. I'll try,” I firmly replied. “I will talk to her. Thank you.”

She had emboldened me, implying I had something to offer that my fellow students didn't. I just needed to work out how to chat up Hannah!

THE END
