I was 25 and randy, but I was also curious. Well, they say curiosity killed the cat, but in my case curiosity got me the cat. I'd better explain.
It was about five years ago and I was just coming off a torrid affair with a lovely colleague, who had dumped me for a much older man, the bastard! The older man, not the lovely colleague.
Sandra said that while my eight inches of uncut cock was very nice, she needed more maturity. Pity, because at 30 she was the type of woman I've always fancied - a mature, big-busted blonde. I go, you see, for older women - not that much older, but at least five years, preferably 10.
I'd picked up one of those glossy magazines that feature ladies in lovely lingerie, mainly for the pictures but also for the words - the words in the massive section of adult advertisements in the back section.
One really caught my eye. It was of a pretty blonde wearing glasses, and a black latex outfit, which showed she had a full, fabulous figure. It proclaimed: "Visit the headmistress. She'll correct all your mistakes, you naughty boy, you!" And there was one of those mobile phone numbers.
Well, I was flush, as they say at poker games. I'd had a big win on the football pools - closer to 40,000 pounds than 35,000 - and I was in one of those "money's no object" moods.
I put the magazine down on my bedside table and stopped whacking off and used my mobile to dial the headmistress's number. It rang only two or three times, then a deep, husky and extremely sexy voice answered.
"Hello, this is the headmistress - more mistress than head. Leave a number, I'll call you back. Honest, you can trust me, I'm a dominatrix!"
And since I always do as I'm told, I left my mobile number, thinking at the time "That's the last I'll hear of the headmistress", and opened the magazine up to resume wanking at pictures of a mature, 40-year-old pornstar.
Ten minutes later, as I was nearing the big O with Mrs 40-Year-Old, my mobile rang. "Hi, this is Lee."
And then the headmistress's sexy voice replied! "Hi Lee, this is the headmistress returning your call. How can I help you?"
I thought you can offer to sit on my face, that's how, but then thought better of it and asked: "I've seen your advert, you look lovely and I'd like to know about your services and charges."
There was a pause, and then the headmistress spoke again, only somewhat warily. "You sound nice Lee, but you also sound young. I don't do young."
"I'm 25," I called out, afraid she was going to hang up.
"OK, you scrape into the age parameters," she said. "Well, I'm a dominatrix, I don't fuck. You can perform body worship, I may give you a golden shower if I like you. And it's a headmistress scenario. You're the schoolboy, you attend class naked and I give you a test.
"Fail the test - and you will fail, promise me, you will fail - and I punish you."
I was hooked. Then she spoke again: "The charge is 200 pounds for an hour and a half, 300 pounds if I use the head girl as part of the scenario. Oh, and from her you will get head."
I was doubly hooked. "How old is she - and how old are you, headmistress?" I asked, adding quickly: "You see I'm into older women."
There was a chuckle. "Most naughty boys are," she replied. "I'm 40 and my head girl is 35. You'll like her, great body, huge tease."
The upshot was that at 10am the following morning - it was a Saturday - I was standing on the doorstep of a rather fancy address not far from Berkeley Square, in Mayfair, with an envelope containing 300 quid.
The door opened slightly and I sneaked in through the small gap to be confronted with a hard-faced woman in her mid-30s. She had long red hair, and sported two ponytails, one of each side, which was obviously an attempt to make her look a lot younger. The smock she was wearing, though, could not hide the fact that she was stacked!
"You must be Lee, the naughty pupil here for his lesson," she smiled, holding out a strong hand, then pocketing the envelope containing the fee. "I'm Raewyn. Follow me and we'll get you ready for the headmistress."
She took me to a small changing room and ordered me to strip. As I did, Raewyn removed the smock to reveal an outfit which would soon have me harder than a length of lead piping.
Her breasts - lovely, lush 36-inch jobs, I later found - were pushed up into mouth-watering uplift in a black satin half cup bra, which did not cover her nipples. Jutting just above the cup line, they were erect.
On her hips was a matching black satin garter belt, which held up shiny black stockings. Her pussy hair was confined to a heart-shaped thatch of redness over her mons. Her shoes were so high heeled it was a wonder she could walk!
When I was nude and stiff-pricked before her, she opened a door on the inside of the changing room and admitted me to the "classroom". In the middle was a desk and chair, all in one, just as in a school. In front of it stood a blackboard. On it the numbers 1 to 10 had been written in chalk.
"Sit at the desk," Raewyn told me, and I obeyed. Then, before I had hardly settled into the seat, she snapped: "Stand up for the headmistress!"
A side door opened and as I stood to attention, prick swaying before me, the bespectacled headmistress entered. She was a superb sight. Blonde hair pulled back into a severe pony tail, she wore glasses and I can tell you Dorothy Parker got it wrong. Men do make passes at girls who wear glasses. At least, girls, or women, I should say, like the headmistress.
She was wearing a black see-through shirt, and her glorious breasts were revealed in it, with big nipples pressing against the material. Her lush hips and glorious bum were covered by a gleaming black leather miniskirt. She carried a cane, wore high heels, but no stockings.
"Good morning, Lee," she announced, standing by the blackboard.
"Good morning, headmistress," I chanted, in schoolboy sing song.
"Nice erection," she smiled, waving the tip of her cane at me. Then, she snapped into business: "Be seated!
"Right, you've got 10 questions to answer, Lee. The questions are each worth 10 strokes. Get them all right and you won't receive a stroke, it'll just be body worship and teasing from the head girl, Raewyn, here.
"For every incorrect answer it's 10 strokes. Understood?"
I nodded and she smiled.
"Good, then we'll begin. What is 'gooch' a slang term for? Raewyn, give him a hint."
And with that the hard-faced redhead stood in front of my desk, turned her back on me and bent over, feet wide apart, clasping her ankles.
Her hairless quim peeped back at me. Gooch? I'd never heard of it. "Er, I don't know, headmistress," I muttered.
"It's the area between the cunt and the anus, you ignorant little boy, you," she informed me. She could have told me it was the slang term for the Horn of Africa and I'd have accepted it.
The headmistress turned, giving me a magnificent view of her great arse as she circled the number "1".
"What is macrophallia?" she asked, glaring at me once more.
"Erm, fucking corpses?" I guessed, which drew a snigger from Raewyn.
The headmistress circled the number "2". "It's the condition of having a large penis," she told me, "and judging by that piece of meat you seem so proud of, I'm surprised you didn't know."
The next question was what does the acronym DATY stand for. I didn't even know what an acronym was, let alone that it was short for "Dining at the Y". The third number on the board was circled.
"Who did Linda Susan Boreman become famous as?" snapped the headmistress. By now my head was reeling, and I should have guessed, of course. "Linda Lovelace," said the lovely "school" head after I had guessed Pamela Anderson. The figure "4" was circled.
And so it went, until I was gulping and contemplating the 10th question. Already nine figures on the blackboard had been ringed.
The headmistress eyed me sternly: "And get this wrong and I'm adding 20 strokes for you being the thickest, dumbest, most stupid student all week." I swallowed at the thought of 120 strokes!
"Who is the president of Ethiopia?" she grinned.
"I haven't the faintest idea, headmistress," I answered, completely truthfully.
"Neither have I," she beamed, "but it's going to cost you 120 strokes!"
"Raewyn, get him into the frame," the headmistress snapped, "while I get ready."
"Yes, madam," said the hard-faced redhead, who then took me by the hand and led me into another room adjoining the classroom. This room was definitely nothing like anything I had come across at my grammar school!
The focal point of the room was a sturdy steel triangle, bolted to the floor and hanging from a length of chain suspended from the ceiling. Straps were at the top where the two side beams joined. Raewyn stood on a chair and with her quim delightfully close to my face, hooked my wrists into the upper straps.
Then she strapped my ankles to the bottoms of the beams, a move which drew my thighs apart and left me totally vulnerable. A broad strip of leather hung across the beams half-way up them and Raewyn pulled my cock and balls through the aperture in its centre, before lacing cords around the aperture tightly around my shaft and scrotal sac, thus enhancing my erection.
She then pulled up a large leather stool and sat in front of me, her face inches from my jutting hard-on. She had no sooner settled than the door opened and in walked the headmistress, carrying two implements, although I hardly noticed them.
She was now naked, save for gleaming black leather boots which came to half-way up her lovely thighs. Her pussy was shaved, her piss flaps peeping out in their pinkness. She had removed the glasses.
Stepping behind me, the headmistress put her face up to my cheek and began to tell me what was in store for me.
"Now, my darling Lee," she said, her voice a whisper against my cheek, "I'm going to give you 10 strokes across your shoulder blades with this cat o' nine tails."
And with that she traced the flogging device's nine lashes across my bare back.
