Her skin seemed to dance in the light from the moon as it rippled through the room, the patterns matching the clouds as they rolled across the sky. Tied face down to the bed, her buttocks seemed to shine in the soft light, although I have to acknowledge that the post winter white of her skin probably had something to do with it. Not that I minded, with skin like that she marked quickly and easily. I quite liked the way her bum almost glowed after a spanking.
Right now however, her squirming was almost hypnotic as her body constantly shifted within the confines allowed by the rope tying her to the bed, her buttocks seemingly in continual motion as the vibrator inside her continued unyielding rhythm. Cycling through random program, the intensity of its motion shifted on a regular basis. It might not make her cum, but it would certainly keep her aroused.
Helping that process were the nipple clamps currently squeezing her nipples, marginally on the inside edge of being just too painful, and the occasional soft caress I gave her whenever I wandered past. Maybe most women would have found the pleasure / pain ratio a little too one sided, but I knew I had the mix about right for her.
She had been in this position for a good 40 minutes. I figured I would keep her there for at least another 20 just to round out the hour. To mess with her head I had already whispered gently in her ear that only 15 minutes had elapsed since I tied her to the bed and inserted the vibrator inside her. Knowing how wet she got in these situations I had taken the liberty of strapping it to her, there was no possibility of it coming out by accident.
After a defined period I would usually release her, then fuck her hard, biting and scratching her body, until I came deep inside her. That would usually trigger a similar response from her, although if I was brutally honest that was just a bonus, she was here for my pleasure.
The last time I took her in this manner she'd cum like a banshee, screaming obscenities in my ear and digging her nails into my skin as the pleasure and pain pushed her over the edge.
Tonight though I had something different planned.
Standing by the edge of the bed I reached out to lightly stroke my fingers down her back. She jumped at the touch of my fingers, then pushed her bum as high her bound limbs would allow as if yearning for me to have access to her body. I reached down to her bum and into her partially open thighs, feeling the wetness of her juices that had spread across her groin and down her legs, almost to her knees.
After smearing her own scent across her mouth and eyes I reached back down to the vibrator and pushed it in as far as it would easily go, generating a moan followed by a plea to fuck her. "Hmm" I whispered in her ear, "you want me do you" I queried softly.
Her reply, whilst positive, didn't really meet expectations so I slapped her ass hard, three times, and left the room, leaving her to her own devices, well really a device in this case.
After about 10 minutes I came back to the doorway. I could see my handprint on her ass moving back and forth as her body continued to gyrate on the bed. Moving back to her I ran my fingers along the outside of cunt, getting them thoroughly wet. I then teased her ass with my fingers as I slowly inserted my index finger into her ass, with only her excretions as lubricant.
As I suspected that was enough, suddenly my finger was deep inside her. Inserting two fingers inside her started to open her up; at the same time she started pushing back in time with my thrusts. I continued this until the ring of my cell distracted me. Withdrawing my fingers, I positioned them in from of her mouth waiting for her to suck them clean. I was gratified to see that she did so almost immediately.
I left the room to answer my phone, as I suspected it was to announce the delivery of my surprise. Buzzing open the access door for the apartment complex, I waited for the knock on the door. I opened the door to see an attractive blonde in brown boots and a shirtdress, obviously trying for corporate chic. Tall, well endowed, with long hair, she looked very "fit".
"Excellent", I thought, she was exactly what I had requested. In essence she was the opposite of my slut tied to the bed who was a brunette, had small breasts and was medium height only in heels.
She smiled as I opened the door, trying to be coy, despite the hardness of her eyes. "Do I meet your expectations?" she queried, "Absolutely" I responded as I let her in to the unit. Having a prior history and credit with her agency meant that we didn't need to go through the usual administrative arrangements of cost and ground rules.
I turned around after closing the door to see she had already unbuttoned her shirtdress. Her body was athletic rather then model skinny, nicely toned and tanned. She stood approx 6' and the boots only contributed a couple of inches to that total. She was wearing Italian style lingerie and looked damm good! Her crowning glory was undoubtedly the impressive cock she appeared to have tucked into her panties. I smiled to myself as she asked "are you my bitch?".
"Not me darling" I replied, "but follow me". I led her to the bedroom were my slut was still in her seemingly perpetual squirming motion. I knew she had a long held fantasy of sex with another woman, albeit from a more dominant position. Too bad, I thought, this was my fantasy.
"She's yours for the next hour" I whispered in her ear. "I don't care what you do to her as long as she gets to cum hard at least once every 20 minutes and she doesn't need to go to hospital afterwards. The only other things you need to know is that she likes pain and has no idea you are here".
A half smile flashed across her face as she contemplated the situation and its inherent possibilities. It was a smile that promised both pain and pleasure for my slut and hinted at the depths of her depravity.
"Will you be joining us?" she whispered back. "Almost certainly" I advised, "but not immediately". "Understood" she replied, "why don't you sit on the Ottoman and watch until you want to play".
The Ottoman was in the corner diagonally facing the bed. As a result it had a perfect view of both the bed and the mirrored built in cupboards at the end of the room. I sat down in anticipation of a good show. I was eager to see if she was able to meet my expectations as articulated to her agency, specifically I wanted an attractive experienced dominatrix with defined physical attributes i.e. big tits and a bigger cock to transform my slut into mindless quivering trannie's whore, desperate for her next orgasm.
Standing behind the bed, looking down on my slut, my hired Dom seemed to freeze for a time as she absorbed the image of my slut tied face down to the bed, still squirming against the vibrator. In reality it was probably only a couple of seconds, but for some reason it seemed longer. The slowly and very deliberately she reached out and gently ran her fingernails over my slut's lower back, causing her to jump.
"Master" she queried slowly as if she wasn't sure if it was my touch. Motioning me to stay silent, the blonde Dom stepped out of her shirtdress and straddled my slut's legs. In the mirrored cupboards behind the bed I could see her panties stretched tight against her ass. She leaned forward draping her large breasts across my slut's back and whispered in her ear "your master has given you to me to play with, I think we should begin".
My slut lay still underneath the blonde Dom, motionless for the first time in almost an hour. Her mind was no doubt racing, whilst we had played some rather intense BDSM games previously, it had always been limited to the two of us. "Master" she called out again, uncertainty throughout her voice.
Her query was interrupted by the blonde Dom abruptly shifting position so she was sitting behind my slut and commencing to spank my slut's ass. I watched with interest as she varied the impact of her hand until her ass was bright red. Every once in a while she landed directly on the base of the vibrator, causing it to thrust even deeper inside. Thirty seconds and maybe 60 spanks later she ceased, the reached forward to grab my slut's hair and pulled her head back so her neck was fully extended.
