Sir and I had a fight. Well more of an argument really. He had made plans for us to spend the whole weekend together, but I had arranged to go out with the girls on Saturday night. I was adamant that I had told him about it a couple of weeks ago, and he was equally sure I hadn't.

Anyway, I did go out and we all had a great time, drinking, dancing, singing along (badly) to a few songs and generally just catching up. Of course a few guys tried their luck, but that's only to be expected and nothing like that happened. Ok, so maybe one girl I'll call Jenna had a bit of a kiss and cuddle with a guy, but that doesn't really count and we all left together at the end of the night.

I slept in late the next morning, so it wasn't until late afternoon on Sunday that Sir came to visit. He has his own key now, so I wasn't too surprised to hear him calling out me while I was still in the shower.

"Give me five minutes!" I yelled back to him as I finished rinsing myself off.

It was more like three when I turned off the shower and towelled myself dry. I reached for the robe hanging from the door, then hesitated. Sir had been gracious in allowing me to enjoy my night out, so why not surprise him?

I stepped out of the bathroom completely naked, and saw him in the kitchen, working the cork from a bottle of wine - which he very nearly dropped when he saw me. He hurriedly put it down and closed the distance between us in two quick steps, taking my hands in his.

"Emily, I need to apologise. You probably did tell me about last night, but I've just been so busy lately..."

I kissed him before he could finish the sentence and launched into my own apology. "It was a couple of weeks ago. It's my fault for not reminding you nearer the time."

After that everything returned to normal between us, and we settled down to watch a film together and drink wine. Me completely naked, and Sir still fully dressed. I loved how vulnerable I felt doing such normal everyday things with my body in full view for him. Knowing he could see my nipples harden when I looked his way, see the dew drops of moisture glistening on my pussy as I thought about the evening ahead.

Naturally I played into the situation, sitting with my thighs parted just enough, bending at the waist to pick up something from the floor, letting my bare breast brush across his arm as I leant across him. I could see the outline of his hard cock through his trousers and I knew I was having an effect on him, but still I was surprised by his response.

Sir is normally a thoughtful lover, every action designed to enhance - or deliberately deny - my pleasure but not this time. With a growl, he pushed me down on my back on the sofa and followed me down, pinning me in place with the weight of hid body.

There was no teasing, no foreplay, not even a word spoken, just the sudden hard thrust of his cock as he buried himself in me. I cried out, more from surprise than any pain, but Sir didn't hesitate. He fucked me with an animalistic frenzy, his cock driving into me like a piston, hard and fast. This wasn't about me any more, but only Sir. Using my body for his pleasure. I was nothing but a vessel for him to use. I loved every second.

I wrapped my legs around him, my nails digging into his back through his shirt, unable to speak, my moans the only encouragement I could provide. In what seemed only minutes, I felt his body tensing as he came. I kept my legs locked around his waist, pulling him into me, wanting his hot seed to fill me, with not a drop wasted.

It was as if his orgasm brought Sir out of a trance. He raised himself up on his arms and tenderly kissed my lips. Without speaking, he picked me up and carried me through to the bedroom, laying me down on the fresh sheets. He kissed me again, then picked up a blindfold from the side table and helped me put it on.

I felt him place leather manacles on my wrists and ankles, and attach them to something. My legs were held spread wide, my hands locked beside my feet. I quickly realised what it was of course, but I didn't know we even owned a spreader bar!

Its hard for me to describe how deliciously vulnerable and exposed I felt in that position. Its Its something you really need to experience. Try laying on your back and holding on to your ankles, then pull your legs wide apart. Now close your eyes and imagine yourself being locked helplessly in that pose.

I heard Sir moving around the room but couldn't make out what he was doing. Eventually he spoke. "You've been such a good girl for me, I'm going to reward you."

With that, I heard the buzzing sound of a vibrator coming closer. I knew Sir would tease me and make me work for my reward and I braced myself as best as I could for the ordeal, so I was doubly surprised when he pressed the toy directly onto my clit running at full power. I cried out at the intensity of the sensation and writhed in my shackles, wanting to escape the torment, yet wanting to prolong the ecstasy too.

"Sir...Please! I'm going to...to..."

He pulled the vibrator away, leaving me with an aching emptiness between my thighs. I sobbed at the loss, feeling my body pulsing and trembling with need. As the feeling slowly subsided, I registered the whine of the vibrator switch to a lower hum as Sir reduced the power level. I bit my lip, knowing what was to come.

After being so close to orgasm, my pussy was even more sensitive than usual, so when he pressed the toy to my clit once more I felt it every bit as powerfully as the first time. In seconds I was reduced to a quivering ball of sensation. I could feel my orgasm there, a web of heat and need spreading through my body.

"Please...please" I gasped out between moans, so consumed with longing that I was unable to form coherent sentences.

Building, building... gone. Sir pulled the vibrator away and I screamed in frustration. I heard Sir chuckle softly and felt his fingertips trail over my cheek. "Patience my pet. Patience" He murmured to me.

Again he turned down the vibrator, the motor barely more than a whisper and all but inaudible through my panting sobs. Again he pressed the toy to my tender clit, and again he drove me to the brink of orgasm. I tried to ask Sir for permission to cum, tried to beg him for it, but the pure pleasure radiating from my core drove away my ability to speak. I dont know if I was moaning, crying or some combination of the two, but Sir read my body like a book and pulled away once more to leave me hovering on the brink.

As I drifted slowly down from the peak of bliss, I felt Sir's lips brush my forehead and he whispered in my ear. "This time my dear. This time I won't stop"

There was a faint click and I waited to feel the touch of the vibrator again, longing for it, but there was nothing. Then, the faintest of touches. Not just on my clit this time, but my whole pussy, my inner thighs, even my ass cheeks. It was barely there, but in my state of heightened awareness it was enough. I bucked my hips against the ghostly caress, moving as much as I was able in my bonds, feeling myself reach the edge of orgasm once more.

"Cum for me. Cum Emily"

Hearing my name fall from his lips was the final trigger and I shattered into a million pieces and became a being of pure sensation.

The next thing I was aware of was Sir lifting the blindfold from my eyes. My wrists and ankles were already unbound and I was safe in his arms. I blinked my eyes against the sudden light and my gaze fell on the vibrator lying discarded on the bed. I both hated and loved it at that moment as the source of my torment and of my pleasure.

It took me several seconds to notice that the vibrator wasn't alone on the bed. Beside it, the blades still spinning, lay a small battery powered fan. Through the treacle that clouded my mind the realisation dawned slowly - that fan, or rather the breeze it created - had been the source of that all-pervasive caress which had brought me the blissful release of orgasm.
