At a signal from my 'twin', the two slave girls who have been attending me release my chains, although when they do and after all the hours chained in that uncomfortable position, my legs are unable to support me and I end up falling face first to the floor.
“Don't get up;” my ‘twin’ tells me holding the leash with her hand, but without actually pulling on it to force me to move. “I like my slave girls to crawl on all fours behind me like the animals they are.”

For the next ten minutes, surely without needing to we walk through half a dozen rooms, where I can watch as some of the slave girls who have been sold at the same time as me are being tattooed, ringed or fucked by their new owners, though in none of the rooms do I see you or the red-haired slave girl you bought.
We finally go outside, and as I suspected at the beginning of the night, we are still in the same building, in the other penthouse of your property. It is raining heavily, and a naked slave girl approaches us with an umbrella to cover my 'twin', not bothering in any way to cover me, causing me to be completely soaked in a few moments.
We enter your attic and head to your bedroom, which causes me to start to feel a kind of nervousness again, thinking that it has all been a game and that you are waiting to release me and fuck me as soon as we meet. Unfortunately, it's all false hope again, when we enter the bedroom you are sitting on the edge of the bed, with the redheaded slave girl kneeling between your legs, sucking your cock while you hold her head.
“You couldn't wait to enjoy that sweet little mouth;” my ‘twin’ says to you releasing my leash to pull you close, lean in and give you a passionate kiss. “Let me show this slut how to suck a cock;” she adds kneeling at your feet next to the redhead.

Unlike what you were doing with the slave girl, at no time do you hold my 'twin's head, you keep your arms at your sides, closing your eyes letting yourself be carried away by the obvious pleasure you are feeling.
Despite the situation I find myself in, I can't help but begin to feel jealous of what I am witnessing, I didn't feel it when it was the slave girl sucking your cock, but I am feeling it watching my 'twin' doing something that I still have a hard time doing. If that jealousy wasn't enough of a problem, my arousal is growing again, I want to feel your cock in my pussy again, even if it's fucking me again as if I were a slave girl like you did a while ago.
“Go and play with Lady Katherine's slave girl;” you tell the redhead revealing the name of my ‘twin’. “And don't stop until she has cum twice.”
A wide grin appears on the redhead's face as she crawls onto the carpet and approaches me, standing on her knees in front of me, though I barely pay attention to her. I notice how tears begin to fall down my cheeks, instead of calling me by name you have referred to me as Lady Katherine's slave girl, making it clear what I am now to you.
To make it all worse, and without taking your eyes off me at any point, you lie down on the bed, helping Lady Katherine to position herself on top of you and slowly lower herself onto your body, impaling her pussy bit by bit on your cock, moaning in pleasure as she does so and exploding in a shattering orgasm.
“I'm sorry;” the redhead says grabbing my face to turn me towards her, seizing my lips in a passionate kiss.
I have never kissed a woman, even though you have asked me several times, I have always refused to participate in your games with the slave girls, now I don't want to either, but I'm not sure I can refuse. After a few seconds I respond to the kiss, thinking as I do so whether the 'I'm sorry' she has said to me is for having to watch you fucking, for now being a slave girl, or for having to kiss me without my permission
Without breaking the kiss, the redhead's hands begin to move down my body, paying attention to my hard nipples before moving down to my pussy to begin masturbating me. I open my mouth to let out a moan of pleasure, but all I get is that her tongue dives deeper into my mouth seeking mine, entwining in an ancestral dance.
Slowly she pushes her fingers deeper into my pussy, pushing me to the floor as she does so, when I am finally fully stretched out on the floor, she pulls her fingers out of my pussy and replaces them with hertongue, licking my insides and kissing and sucking my clit.
My moans mingle with those of my 'twin', whom you are now fucking on all fours on the bed, grabbing her arms and pulling them back, treating her as if she too were just another slave girl.
Between tears mixed with the pleasure that runs through my body and the disappointment that you have never fucked me like that, I reach my first orgasm thanks to a woman, surely since my mistress is a woman, the first of many. Despite my orgasm, the redhead doesn't stop, you've ordered her to bring me to two orgasms and she seems willing to do your bidding without hesitation.
Her initial two fingers have become first three and then four, stretching my pussy, opening it, exploring every nook and cranny. In addition to her fingers in my pussy, the redhead has introduced two of them in my virgin ass, provoking me by moving them a strange sensation that brings me to the second orgasm.
“You have done well to buy a lesbian slave girl;” I hear her tell you to my ‘twin’ standing on her feet in front of us, perfectly dressed, only her slightly tousled hair and ragged breathing revealing that you have fucked her and brought her to two intense orgasms. “I can't wait to see how she makes that prissy Patricia cum over and over in front of all her friends like the slut I've always known her to be.”
“Easy Kate;” I hear you tell her. “We don't know if Patricia is going to keep her bet and agree to be my slave girl for the next two weeks;” you add.
“Of course she will, she has given her word and cannot back out;” Lady Katherine replies. “As soon as she see you arrive leading by a leash that slut that looks so much like me and you show her the papers we have prepared for her to believe that I am your slave girl for the next two weeks, we will have her as our slave girl all that time, and before that time is up, we will make her permanent slavery;” she add smiling.
