Her name was Justine, and I had met her a few times during my badminton sessions at the sports club.

Quite young, I'd put her at between twenty and twenty-five, and certainly under thirty. She was of average height, with a slim waist, nicely rounded hips and a nice, firm, plump buttock, most of the time molded into a pair of smart leggings that showed her off perfectly. It was difficult to estimate the size of her breasts, as they were probably compressed by a sports bra, but it was certain that there was a minimum of material held in there.

Her wavy, rebellious chestnut hair, which she kept in a high ponytail, crowned a very pretty face which exuded innocence but which was regularly lit up by a mischievous and sometimes naughty look in her blue eyes.

She was a pretty girl, cute and friendly, and I found myself observing her as she sweated on the pitch, imagining her wearing far less clothes and sweating for many reasons other than club sport...

Up until then, our exchanges had been limited to a few tips on how to play and a few smiles punctuating the points of hard-fought games.

We were in a small town, and it was very common to bump into a friend or acquaintance on the road, in the supermarket or in the few shops in the town, and that day was no exception as I found pretty Justine stranded in the almost deserted supermarket car park.

The young woman seemed to be in a bad situation, with a boot full of shopping and a car that wouldn't start.

With no hidden motive and only my ideal of a knight in shining armor, I parked next to her car to offer my help. Although I wasn't a mechanic, I quickly identified a simple battery problem and started his car using the cables I kept in mine.

I then offered to escort her home to make sure she didn't break down again on the side of the road.

As I pulled up in front of her house, I rolled down my window to say goodbye when she asked me to come and have a drink with her to thank me for helping her.

At first, I refused, as I had not expected anything in return, but she was so insistent that I finally agreed and followed her car to the car park in front of her building.

After helping her upstairs with her shopping, I found myself standing in front of the bay window of her terrace, admiring the view of the city and the sea in the distance as I sipped a cold beer while she put her shopping away.

I was suddenly startled, almost spilling my beer, when Justine came up behind me quietly and put her hand on my crotch.

‘I think you deserve more than just a beer for coming to my rescue today,’ she said in a warm, naughty voice.

‘I, I... listen it's lovely and very tempting but I don't deserve so much and anyway, I'm married and faithful so I'll pass,’ I said as I turned to face her and took a step back.

She had taken off her clothes and was presenting herself to me in a ravishing set of blue lace lingerie, almost matching her eyes. With fevered eyes and quivering lips, she moved closer to me again and put her hand on my sex, which was slowly beginning to awaken under my shorts.

‘But you can't deny me that,’ she said, ’I'm all wet already and I just want to suck you off and feel your cock deep inside me!

I wasn't mistaken about that mischievous look, the little girl was as hot as embers and wanted nothing more than get fucked brainless, but there you go, faithfulness obliges, I couldn't give in.

There followed a confused melee during which I tried to push Justine away as she desperately tried to hold on to my cock while rubbing her breasts against my chest.

‘Justine, that's enough now get off me right now! Don't make me get angry!’

The ridiculousness of the situation and of my exclamation was not lost on me, but I had to raise my voice to reason with her.

She stopped suddenly, surprised by my outburst, her eyes wide and her mouth half-open.

‘Make you hungry?’ she said. ‘What's wrong with that? Would you be capable of spanking me perhaps?’ Surprise was quickly replaced by provocation. The desire and excitement had already returned to her eyes.

I looked at her dazed by this unexpected turn of events. My brain was on the verge of shutting down, sending me dozens of suggestions every second.

To this day, I'm still convinced that I chose the right one...

‘All right!’ I said. ‘You leave me no choice. Take off your panties and come here on my knees,’ I said, sitting down on the sofa.

She obeyed immediately, got rid of her lovely knickers and came to lie on my lap, her pelvis pressed against my right thigh, her hands and feet touching the floor on either side of my knees, her head lowered between her arms.

What a delicious view! Her buttocks looked magnificent in that position. She'd kept her legs together so I couldn't see her sex, but I could smell the arousal, which made my mouth water. I imagined her sweet, delicious pussy just waiting to be tasted and then taken with great strokes of my cock.

‘That's the perfect position to punish a wanton little slut who doesn't listen to her Master. From now on, I don't want to hear anything other than Yes Master, Thank You Master and the count of each strike on your arse. You've earned ten strikes on each buttock, and you'd better not get the count wrong or your punishment will be extended.’

‘Yes, Master. Thank you for punishing me, Master.’

Without waiting for her to finish her sentence, I struck the first blow on her right buttock. I'd raised my hand high and if I hadn't used all my strength, I still hadn't come very far.

Justine gasped and gave a stifled cry of surprise but soon started to count.

‘Ooh! One... thank you, Master.’

I wasted no time and treated the left buttock in the same way immediately.

 ‘Huuumpf... One, thank you, Master.’

I could already see the imprint of my hand in red on her right buttock, so I shifted my second and subsequent strokes to cover all the available fleshy surface.

By the time I'd made my fifth stroke, Justine's entire arse was peony red, and I thought I felt a sensation of moisture on my thigh where her lower abdomen rested.

So far Justine had shown exemplary control: she had hardly flinched at each blow and had mastered the countdown and the thanks perfectly. Having reached the halfway point of the punishment, was she going to be able to cope with the rest just as well?

Before resuming, I confess, I took the opportunity to run both my hands over these two superb buttocks offered up to my caresses. A brief moan escaped the penitent's lips, but I couldn't tell whether it was from pain or pleasure. Her ass was exquisitely soft and now radiated a pleasant warmth.

‘It's time to pick up where we left off, little slut. Are you ready?’

‘Yes Master, I'm all yours.'

She'd easily switched to being formal without me even asking. Our relationship had shifted into another dimension: what had started out as an attempt at seduction had become a sort of game, and finally evolved into a relationship of domination/submission as if by magic. I hadn't wanted it and I don't think she had either, but the mechanisms had worked themselves out with disconcerting ease.

I've always been what's known as a 'switch': I like to dominate as well as be dominated, even if I think that when faced with a woman I'd tend to prefer to be the submissive, but in this case and on that day, the positions were clear and perfectly defined, as the throbbing little arse under my hands could testify for it.

I sent the next salvo, taking it from approximately the same spot as the very first strike.

Justine couldn't hold back and let out a cry of pain.

‘I thought I said I didn't want to hear from you again, slut! We're going to have to retake the sixth stroke for your trouble. Get up this instant and fetch me your knickers!’

‘Yes Master, right away.’

She got up with some difficulty and went to get her knickers, which she had left a few feet away. Seeing her little red bottom wiggling in front of me was an unimaginable pleasure. I could see that the little bitch was indeed enjoying the situation, as she had thoroughly wet my thigh.

She came back to me and handed me her panties.

‘How dare you?’

She looked at me quizzically.

‘How dare you present yourself to me like that. That's not an acceptable position for a slave! On your knees! Legs apart, back arched, arse back, eyes down and you raise your arms to offer me your knickers! You've just earned yourself two more rounds of slaps, little slut!’

She complied immediately and waited wisely for me to take the knickers from her hands, which were outstretched like a display case above her head.

The word was out. It was accepted. The position was adopted. The transformation was complete: I was the Master, she was the slave without any discussion whatsoever.

I grabbed her panties and brought them up to my face to smell the delicious aroma. The little slut had wet herself long before she landed on my lap, no doubt about it!

‘Open your mouth!

I rolled her panties into a ball and shoved them into her mouth.

‘You can bite down on them to stop your screaming and anyway, even if you do, we shouldn't be able to hear you now. You won't be able to count any more, but I'll take care of it. Get back on my lap!

‘So I'll take the sixth stroke again.’

I brought my hand down on her right buttock again and announced with a smile, ‘Six!’ before moving on to her left buttock.

Poor Justine squirmed in my lap with each stroke and I could vaguely hear her moans muffled by her juicy gag.

Her ass was getting hotter by the blow, slowly turning a purplish red as I finally delivered the twelfth stroke on her left buttock.

I reached out to take the panties off her mouth and immediately heard her gasp and murmur:

‘Thank you for punishing me, Master. Can I cum now, please, Master?’

Unbelievable! I hadn't even ordered her not to cum, but my delicious slave with her ass on fire had restrained herself by her own will.

‘No, you'll have to wait a little longer, you greedy slut.’

A groan of frustration escaped her lips as I gently caressed her sore, burning bottom.

‘Spread your legs a little.’

She obeyed immediately and exposed her drenched sex, quivering with desire. I ran my thumb along the length of her slit to retrieve a little of her offering and brought it to my mouth. The smell was intoxicating and the taste was exactly as I'd imagined it: sweet and slightly tangy... a great vintage indeed!

I repeated the same manoeuvre with my thumb, but this time I inserted it between her shapely bums to deposit this natural lubricant on her throbbing anus.

I heard another moan, followed by a revealing ‘Oooh’.

I gently massaged her little hole, applying gradual pressure, pushing her sphincter to the limit of penetration.

My new slave was exemplary in her behaviour: she didn't move an inch, waiting for the inevitable moment when I would penetrate her.

There was no reason for me to rush things, so I made the pleasure last as I watched her pussy leak wetness in an uninterrupted stream. I could hear Justine gasping for breath, obviously gritting her teeth so as not to risk further punishment.

I held up my index and middle fingers and, in one swift movement, penetrated both her orifices, thrusting my thumb to the hilt into her tight arse and my other two fingers as far as I could into her flooded sex.

‘Aaah, yes, yes, yeees!’ she cried, savoring the delicious sensation that shot through her and the premises of her long-awaited orgasm.

‘Master, please, can I come? Please, Master, I can't take it anymore.’

‘No, still not, my little slut. Patience is the queen of virtues.’

Then I put my left hand on the small of her back to hold her firmly on my knees and began a powerful and rapid back-and-forth movement with my other hand, savagely fucking both her orifices with my fingers.

She screamed loud ‘Aahs’ every time my hand went deep, and her whole body contracted and relaxed to the rhythm of my frenzied penetrations. I had a feeling she wouldn't be able to keep control for much longer, and she'd deserved to come at last.

As my arm moved back to initiate one last liberating penetration, I finally let go:

'Come, my little slut, come now!’

And I pushed my fingers into her pussy and ass one last time, pushing as far as I could.

My words and my fingers triggered an immediate tidal wave. I felt a flood of wetness run over my hand as every muscle in her pussy and ass contracted and gripped my fingers in a velvet vice.

‘Yeees...’ The word came out of her mouth and went on for several long seconds until all the air in her lungs had been expelled.

She remained tetanized on my knees, not releasing my fingers while the orgasm that ran through her insinuated itself into each of her nerve endings and annihilated all other sensations, depriving her momentarily of all her senses.

This moment, which probably only lasted a few seconds, seemed interminable and I was about to get worried when I felt the pressure release on my fingers and her whole body slowly relax until she was like a disjointed puppet, abandoned in my lap.

She breathed slowly, no sound coming from her mouth and only a few shivers running through her strained body from time to time.

I gently withdrew my fingers from her satisfied orifices and stood up, carrying her in my arms. I went to her room, laid her on her bed and went to look for a moisturizer cream in her bathroom.

I then spread the cream on her still-warm bottom with the lightest, gentlest strokes possible.

She hardly reacted during this treatment, she was still lost in her world of extreme and liberating sensations.

I gently kissed her delicious ass, covered her body with the sheets and left her flat without saying a word, leaving her scent still present on my fingers and my shorts.
