It took a moment, but eventually Marie came forward to where I could see her fully. I gasped in my gag, and moaned when I realized that Julie's other sub was actually Gwyn, my wife, and that she was wearing a large strapon and was about to fuck me the way I had been asking her to do for far too long.
"Thank you, Dave.", Gwyn said. "I didn't understand what you needed, and I had a chance to reconnect with Julie, and for that alone I can never repay you. I hope that you feel ok about everything we set up for you. I know that you never had a chance, as I told Julie everything about you - all your kinks, fetishes, desires, even that you love to lick my asshole and that you always wanted me to shave. Julie took charge and made everything happen for me - and she really is great at solving people's problems. I promise to talk about how this all came to be at some point in the future, but just believe me when I say how much I love you, and always have and always will. I want Julie to be in charge, and I will do anything for either of you, just in different ways."
Then my wife leaned over me and caressed me, and kissed my head, and rested with her exposed breast resting on my head.
"Enough" said Julie. "Gwyn has a job to do, and I'm going to make sure it gets done well - in fact I may take a turn myself.
Gwyn stood up, and Julie kissed her deeply before she moved back towards my outstretched ass. I heard the squirt of the lube bottle just before I felt her fingers playing around my asshole. Gwyn took her time tugging on the plug, and reaching under me to play with my rock-hard tool, even adding a little extra lube so that while I was rubbing myself on the leather of the bench, it was more slippery and smooth. Eventually she took a firm hold of the plug and pulled more steadily until she could work it most of the way out of me, and let it pop right back in. She played this game for until she gave the plug one last little tug and it popped right out of me and I flinched. She stood back, I assume watching my gaping asshole close up slowly, and then she brought the buttplug forward and put it in front of my face. It was larger than anything I had ever played with, and I was amazed at how thick the base was. It was the kind of training plug that was designed to stretch me, and make it easier to fuck my ass.
I felt Gwyn position herself between my legs, and centre herself behind me. She squirted another dollop of lube between my cheeks, and proceeded to slowly work two fingers, then three, then four into my gaping hole. I moaned with each extra finger, knowing that she was stretching me and preparing me for the purple silicone cock she wore in her harness. I knew it was time when all the fingers withdrew, and she shifted herself so that the head of the purple monster was resting on my hole.
I had been asking for years for Gwyn to buy a strapon and fuck me, just like this. I had fantasized about her dominating me, using me, tormenting me, stretching me, and eventually taking me with a fake cock, but when Gwyn started pushing herself into me, the reality of the fantasy struck home a little to hard. When I started to moan too loudly, Gwyn backed off because she was nervous. I knew that she didn't want to hurt me, but I wanted this more than she could possibly imagine. She would get started pushing and make it almost to the point where she could push further, and then back off again. It felt like she was teasing me, but I suspected she was just afraid to finish the job. Julie walked back and whispered in her ear. I could hear them talking, and then Gwyn slowly pushed forward, and moved in and out a little at a time, before finally thrusting her hips and fully lodging the purple cock deep in my ass. She stopped there and held her position for a moment, breathing deeply and pressing gently on by back. It wasn't long before I started trying to rock my hips further back and ride her in and out of me, all the way to the hilt. I strained, and it hurt at moments, but as I relaxed, she relaxed, and she started to work the dildo in and out of me, fucking harder and harder as Julie commanded her. I noticed that Gwyn was starting to moan as well, and then the moaning stopped when Julie moved to stand in front of me.
Julie unhooked my gag and pulled it out of my mouth, but my jaw didn't get much time to rest before Julie filled my mouth with the pink strapon that she had harnessed around her hips. Julie and Gwyn rocked back and forth, spitroasting me, fucking me everywhere, and every way that they could. I was in heaven, and hurting everywhere, and lost to all thought. When I finally came, after a day of intentionally arousing myself, and an afternoon of sexual torment at the hands of a dominatrix and my wife, I had lost all control. I shot my cream on the leather bench underneath me as my mistresses fucked and fucked and fucked. At some point I completely stopped moving, and the two of them backed out of me, and checked in to make sure that I was OK. They were both very caring and got me some water to drink. While I was resting, relaxing in the afterglow of orgasm, and feeling my ass contracting, and my jaw softening, Julie started to take command again.
