I couldn't believe what I had just heard. Miss Rose was going to let me do whatever I wanted? Well, within reason, of course. I didn't expect to be given such freedom. Hell, I didn't expect to actually succeed in holding back my orgasm. I knew that she could have made me cum if she really wanted to. She had let me win, but that didn't dampen my excitement.
I thought about what I might want to try as Miss Rose released me from my bonds, unbuckling the straps around my wrists. I had already done so much in such a short window of time, and I was still so inexperienced that I didn't really know what else there was to try. As I pondered, my mind became distracted by the intense throbbing in my loins that refused to go away. It felt like I needed to cum, like nothing else mattered aside from my sexual release and I'd never felt that kind of hunger before. But I knew that whatever I decided to do next, Miss Rose wouldn't let me cum yet, so I would have to choose something that wouldn't be directly stimulating to me. That gave me an idea.
"Miss Rose, can I use the strap-on on you?" I asked as she unclipped my ankle restraints.
"No," came a quick reply from Miss Rose, unbuckling the straps around my ankles.
"But it doesn't have to be dominating," I said, trying to be persuasive. "You can tell me how to fuck you and still give me orders and stuff."
"I said no, kitten," Miss Rose repeated. "That privilege belongs to only one woman. Long ago, the last time I slept with Fräulein Chiara, she told me no one is allowed to fuck me with a strap until the next time we sleep together. Just like you shouldn't disobey me, I will not disobey her."
That put a wrench in my idea. I wasn't sure what else to do. The more I thought about it, the more appealing the idea of using the strap on someone else was. But I had to respect Miss Rose's obedience to her domme. Then it came to me. I was controlled by Miss Rose, and she was controlled by Fräulein Chiara. It was all about control, so maybe she could control me with the strap on a third woman. But how could I broach that subject? I couldn't just ask her to invite another woman over, could I? And who would she invite? Who would respond so late on a Sunday night?
No, that was a stupid idea. I shook my head, trying to dismiss it from my head.
"What's wrong, kitten?" Miss Rose asked. "You looked like you wanted to ask something. Out with it."
Well, I guess this is as good an opportunity as any.
"What if I didn't use it on you, but on someone else? And you could tell me how to fuck her," I suggested, half mumbling sheepishly.
Miss Rose looked ponderous for a moment, taking in my idea and letting it soak in her brain.
"That's a very bold request," she finally said with a smirk. "But I actually like it. It's been a good long while since I've had a threesome. I think I know who would be willing to join us too."
She went over to her chest of toys and pulled out the strap-on harness she had used with me the night before, and then grabbed a medium sized, seven inch dildo to attach to it. She put it together and handed it to me.
"Keep your outfit on, and put this on over it," she ordered. "I'll be back, I need to get my phone from downstairs."
With that, Miss Rose left the bedroom, leaving me alone to put the harness on and wait for her to return. When she came back a few minutes later, I was sitting on the bed with the harness on over my panties and garter belt. She came over and had me stand back up so she could check the straps and make sure it was on securely and wouldn't slip or fall down.
"Our guest will be here shortly," Miss Rose said. "She doesn't know you're here, so I want to give her a little surprise. I've put a blindfold and noise canceling ear muffs in the closet for her to wear, so she won't see what's happening, and she won't hear me giving you instructions."
Her idea sounded super hot, and actually made me want to try it instead, but I had to wonder how the other woman might feel about the trickery. Knowing how Miss Rose felt about consent, it seemed a little bit out of character for her to want to trick another woman into sex with someone she's not expecting.
"Wait, won't she be upset if she finds out she's being touched and fucked by a stranger?" I asked.
"Well you're not totally a stranger to her," Miss Rose explained. "You've met her before, and this is one of her kinks. She loves sensory deprivation and has told me that this is a fantasy of hers, to be blindfolded and fucked, only to find out the person who fucked her isn't who she thought. So don't worry, I assure you she wants this."
"Ok," I nodded, feeling a little better after that explanation.
Miss Rose reached over and cupped my cheek reassuringly.
"She trusts me, and you trust me, right?" She asked. "And you know that I would never do anything that might jeopardize that trust."
I nodded again, feeling confident that Miss Rose knew what she was doing. She was right. I put far more trust into her than I'd ever done for anyone else, so I had to believe that it was as sacred to her as it was for most normal people.
"Good, now go stand by the closet," Miss Rose ordered. "When she gets here, you'll need to guide her to the bed. Don't be timid. Act with confidence like I would. If you don't, she's gonna know something's not right."
Just then, the call box by the bed chimed, which I guessed meant someone had just entered the penthouse via the private elevator. It hadn't been very long since Miss Rose had contacted whoever it was, so she had to have been close by to get here so quickly.
"Come on upstairs, Melissa," Miss Rose said through the call box. "I have some things for you to wear in the closet. Put them on and knock three times on the inner door when you're ready. I'll be waiting patiently for you."
"Yes, Miss Rose, I'll be right up," the familiar voice replied through the speaker.
So it was her personal chef, Melissa, whom she had invited. No wonder it didn't take long, she must have been waiting on call in the building still. I had met Melissa only a brief handful of times over the past few days when she came up to cook the occasional meal for us. She was nice, and very attractive, but that's to be expected from a former auction prize, so I was actually relieved to find out she would be the third woman in our ménage e trios.
Even still, I nervously waited by the closet door for her to arrive. I felt kinda weird just standing there with the harness on, dildo sticking straight out in front of my crotch. Every time I moved, it wobbled awkwardly. Soon I heard the outer door open and close as Melissa entered the closet to undress. A few moments passed, and she knocked three times on the inner door. I looked over to Miss Rose, who gestured for me to open the door and lead her inside.
