Nikki was a beautiful sight to watch, when she moaned, squirmed and panted, as she came closer and closer to orgasm. I took immense pleasure in knowing I was the cause for her state of mind; she was a pretty sex kitten. Since I was so involved in taking care of her, I didn't hear the door opening behind me. In fact, I only became aware of another person's presence in the room, when fingers started caressing my bare ass, again thanks to my small skirt. Not turning my head, I continued nibbling on Nikki's red pussy; she was multi-orgasmic, so as long as I continued my attention on her, she was on a constant high. The fingers, still foreign to me, persisted and the hands closed around my waist, pulling me up on my knees. They didn't stop there, but continued their journey in between my slightly spread legs. At the first contact against my clit, I shivered and turned my head to see to whom the hands belonged.
Kate had finally come in and she was drawing small circles on my clit slowly, completely focusing on what she had at hand. As her golden bikini had somehow disappeared, she knelt completely naked behind me. When she saw me looking at her, obviously distracted from my previous engagement, she pushed my face back into Nikki's pussy with her free hand. I didn't see or hear whether an inaudible conversation progressed between Nikki and Kate from over my head, but Nikki wrapped her legs around my head this time, showing me she wouldn't let me go easily. I felt the warm and wet fingers leaving my pussy, which was my cue to relax my legs and sit on my knees as I'd done before. I couldn't see what was coming, but I wasn't too worried at the time.
Kate came back after a minute or two. This time, her hands were more hesitant and didn't spread my legs immediately, but when they did, her fingers slid in me so easily. It wasn't just because of my wet pussy, she had lubed her hands. She made a come-hither gesture inside my pussy, rubbing my g-spot, which basically drove me crazy. I started pushing myself back on her fingers, enjoying the slippery penetration and moaned into Nikki's pussy, which was now red with arousal.
Nikki was on fire! Her sweet pussy was dripping and it smeared my face as she pushed her hips onto my face, begging to be fucked. At one point, she got more vocal than just moaning and asked me to fuck her hard. Kate stopped fingering me at that point and went away again. She handed me a silver vibrator when she returned, and Nikki finally allowed me some space to pull my head back. After fingering her a little, I pushed the head of the vibrator in. She spread her legs wide on the sofa and stretched, accommodating the toy inside her then I pushed it deeper. Before turning it on, I used the toy like a dildo, fucking her slowly but going deep each time. Her reaction was very high-pitched, when I turned the vibrator on; so this time, I used shorter and faster strokes, pulling it out completely at the end to make sure it hit her clit, as well.
After a short while, I had a steady rhythm on Nikki. I guess Kate was watching us in the meanwhile, later she decided to join in. Holding my hips up, she spread them a little and then I felt the push of a thick object at my pussy. She had good reasons for lubing me up before, because the toy which was slowly sliding into me was stretching me like there was no tomorrow. It was taking a while to get it all inside me and Kate wasn't that patient; she pushed it inside me. I let out a loud moan, for which she spanked my ass hard. Trying to distract myself from the pain, I concentrated on Nikki, who was eagerly riding the vibrator. The noises she made turned me on even more, making Kate's abuse more pleasurable.
Once I could ride the dildo at the rate Nikki was riding hers, things got better for me. My pressure on Nikki grew slowly, hitting her a little harder each time. Judging by the color of her pussy and her warmth, she looked close to exploding. I leaned in again and licked her clit in short strokes, which finally sent her over the edge. After her orgasm had come to an end, she slowly pulled the vibrator out of her pussy and lay on the couch, exhausted. My ride, on the other hand, was only getting started. Kate flipped me over and I sat on the carpet, facing her, watching what my mistress would do to me. She went to the chest by the wall; put the vibrator and dildo back in and took out a strap-on. Its size, although smaller than the previous dildo, was still big enough to frighten me, but resisting would do me no good, as she came onto me quite fast, pushing me onto my back on the floor. She knelt in front of me and adjusted the strap-on. I felt the entire fake dick inside me and all I could do was moan with a mixture of pain and pleasure. When my moans got louder, Kate leaned on me as if to lock me in a kiss to subdue my voice, but instead slapped me hard and told me to take it like the bitch I am. In order to prevent more violence on her part, I tried to be quieter and spread my legs more, hoping it would please her.
Smiling, Kate continued fucking me hard. When she no longer needed the support of both her hands to keep me in place, she used her right hand to play with my clit, making sure I would be wet a bit longer. I was almost going to close my eyes and let things go downhill from there, but Nikki snuggled up to Kate from behind, her white hands pinching Kate's pierced nipples in front of me, making her moan, as well. All I could do was lie on the floor, feel her pounding my pussy and try to keep quiet, but I couldn't do it anymore with a skilled finger flicking my clit and the sight of them. My toes at the end of my wide spread legs were starting to feel numb and I could feel the heat rising up in my body, especially in my crotch. With one last effort, I started moving my hips to Kate's movement and felt the strap-on hit me harder and deeper. It took about a minute before a giant orgasm rocked me, contracting my muscles so hard that Kate couldn't move the toy in or out anymore.
I took my time getting up; I had been alone in the room for 10 minutes, since the girls had left to do another show onstage. After pulling myself together, I walked back to the silver hallway and out the doors. It was only when I got home that I realized I had left my thongs there...
