I'd been looking forward to this day for some time now. Meticulous planning, collection of the precise items I'd sought, all done discretely without her knowledge, in preparation for pleasure.
Pure selfish pleasure, hers and mine, but in very different ways.
I heard her key turning in the lock of the front door, and the everyday sound of it closing behind her as she arrived in the flat.
"Hey, honey," her soft, gentle voice called from the hall.
"Hey, you," I replied, my usual greeting in a carefully neutral voice. "How was the office?"
She sighed as she appeared in the doorway, her uniform blue skirt and jacket, her lilac blouse, all sitting nicely on her curvy frame. "Another day of boring routine crap broken up by occasional bits of interesting gossip," she replied, shaking her hair out of the tight ponytail.
I stood up. "Follow me," I said simply, heading for our bedroom.
I held the door open for her as she entered, looking at me curiously as I closed it behind her.
I folded my arms and turned my cold look on her, my eyes flat. It was a look she knew all too well.
"Take your clothes off. All of them."
She regarded me for a moment, and saw the look in my eyes. She knew it would be pointless arguing with me when I was in this mood, the same as she knew that if she didn't do as she was told right there and then, I'd tear the clothes right off her, work uniform or not.
"Strip!" I snarled at her, and she jumped, startled, and began to quickly shed her clothes. Her jacket and blouse fell to the floor, quickly followed by her skirt. She kicked off her shoes, and took off her tights, then panties, and lastly her bra.
I passed my eyes over her naked form, seeing the lines from her underwear and skirt on her body, seeing her pussy that needed shaving again, that slight stubble that I knew she hated.
I looked her in the eyes, and I could see the curiosity and fear there. The two sides of that mystery and desire within her, wanting to know what was coming but scared to find out.
"Bed," I said, motioning with my head as I dropped to my knees at the foot of it. She got on all fours on the bed, and I positioned her with her head at the foot of the bed, on her back.
"Give me your hands," I ordered, pulling them through the wrought-iron bars of the footboard. As soon as they were through I lifted the newly-purchased stainless steel spreader bar, complete with wrist and ankle restraints.
She gasped as she saw it, her eyes widening.
"Shut the fuck up," I told her sternly, not wanting to hear a word from her.
I opened the two central restraints and fastened her wrists in, locking them tight on the outside of the bed frame, securing her to the bed.
I rose to my feet and prowled, slowly walking around the bed, eyeing her naked form.
"Who's my personal slut?" I growled.
She swallowed, watching me carefully. "I am, Master," she whispered softly. I cast my eyes down to her pussy, unsurprised to see it glistening with moisture. I knew this turned her on, made her horny.
"Pull your legs up, slut," I ordered.
She tried to lift them both up over her head, but she couldn't quite manage to get them under the headboard on her own.
I moved to the foot of the bed and opened the two ankle restraints, then grasped her ankles and paused, looking at her, watching as she licked her lips, her breath already coming in nervous gasps.
I yanked her legs hard, pushing her feet through the narrow gaps in the frame, and hauling her hips up off the bed by a couple of feet. Within seconds I had her ankles secured, and I ran my cold eyes over her once more.
Her shoulders and upper back were on the bed, but her pussy was pointing almost straight upwards. Her buttocks were spread wide open, exposing her little tight hole, and her legs were framing her face.
"Uncomfortable?" I asked unemotionally.
She opened her mouth to answer, then quickly bit her lip, knowing she shouldn't reply unless I addressed her directly, unless I called her 'slut'."
I landed a hard, almost vicious, open handed slap right on her buttock, feeling the tingle in my fingers as I watched the red hand print surface on her ass.
I barely registered her sharp intake of breath, or her high-pitched squeal of surprise. I wasn't interested in her reaction at that point. I was fascinated, as always, with the way her skin reacted to certain stimulus, and at that, I smacked her other buttock just as hard.
The ring of the slap of flesh on flesh echoed around the room, and I grinned in satisfaction at that beloved noise.
"Do you want to please your Master, my slut?" I whispered softly.
"Yes, Master," she replied quietly, her voice quivering slightly.
I nodded approvingly, and dropped to my knees and removed a small holdall from under the bed, dropping it under her buttocks, where I knew she wouldn't be able to see the contents.
"That's my slut," I said in low, menacing words as I took the first of the new toys from the bag.
The vibrator I had removed from the bag was pretty average in size, pretty normal in shape, but was made of stainless steel, and up until five minutes ago, it had been in the fridge, and was still freezing cold to the touch.
I touched it briefly against her asshole, making her flinch at the coldness, but my intent for this new toy wasn't in her ass. I positioned it at the entrance to her pussy, and without ceremony, as if sliding a tool into its holder, I pushed it into her cunt. She gasped as the cold steel entered her warm hole, the temperature as big a stimulus as the penetration, and I turned a warning gaze upon her. She knew the rules, and the consequences of breaking them.
