Sir sat me down on the settee.

“Tell me your thoughts about Susan, Evelyn?" He asked me.

“What do you want to know, Sir?"I asked, a bit puzzled.

“Do you trust her, Evelyn?" He now asked me, being unusually serious.

“I don't know her too well, Sir. But I could see she was very inquisitive about me being a whore." I told him honestly.

“Hmmmm, I just got from first impressions that it's you she really wants, Evelyn, just from things she said.” Then, she continued “, And she will struggle to be a whore in demand if she can’t suffer pain. She’s the first Whore I've had who's used the safe word that quickly."

He then laughed, “Nothing I have done to you has brought you close to using the safe word, you have been the biggest pain whore I've had. Complete opposite from Susan," as he now hugged me.

“Evelyn, please be careful of Susan and tell me immediately if she tries to dominate you as she did at the weekend when I was away.”

I looked at Sir, seeing real concern in his face, “Yes, Sir, I will be careful."

Over the next couple of days, I received a few texts from Susan, seemingly excited about Friday, asking if I knew what Sir had planned, which I didn't.

Sir was out on business on Thursday when my phone rang. It was Susan.

Answering “Hi, Susan honey, how are you?"

"Hey, Evelyn. I'm good, excited and horny, wondering what is in store for us tomorrow night. Do you have any idea what it is?" she asked.

"Sorry, no, Susan, Sir hasn't spoken about it, but whatever it is, it will be amazing." I tried to reassure her.

“Is he around now?" she asked.

“No, he went out to attend to some business, he said"

"Ah, okay. Part of my excitement is seeing you, my sexy little bitch, in action. I so loved having you as my bitch the other weekend, Evelyn." Susan now said.

“I'm Sir Whore Susan, so that can’t happen again," I told her, remembering what Sir had told me.

“Did you enjoy being my bitch though, honey?" Susan asked in a friendly voice.

I wondered how to reply, as I had enjoyed Susan leading me around the house on all fours, using my collar and leash.

“Y. Yes, I D. Did." I kind of stuttered a response.

“Good, my bitch." as Susan laughed on the phone.

“Okay, I'd better go, glad I spoke to you, Evelyn, and I so look forward to being your sister whore tomorrow night," Susan said.

Giggling, I said, “Bye, sister whore," as our call ended.

Sir arrived home about an hour later.

Giving me a hug and a kiss, “What has my gorgeous whore been up to?"

“I spoke to Susan on the phone," I told him.

“Oh, and what did the little whore want?" he enquired.

"Oh, she's just excited about tomorrow night, Sir, and wondered if I knew what you had in store for us." I just replied, not wanting to get Susan into more trouble with Sir, as it was nothing really.

“Oh, you will both find out tomorrow, my whore." Sir smiled now.

“Well, she was excited she would get to see her sister whore in action again." I giggled now.

Sir just hummed “Hhhmmmmm,” as he went through to the bedroom to change out of his business suit.

On Friday evening, Sir took me to the hotel around 6.45 pm, so that we would be there when Susan arrived.

The lift pinged at 7 pm, and Sir let Susan into the penthouse.

She looked at the room, “Oh God, this is amazing," as she came across and hugged and kissed me first. “Mmmmmmm Evelyn, my sister whore."

Oh, dear, that wouldn't please Sir. I was thinking to myself. After all, she was his whore now.

She then went and greeted Sir, but not as excitedly as she'd greeted me.

I saw Sir raise his eyebrows.

“Okay whores, time to get changed,” as he took us into the main bedroom, where two sexy maids' outfits were laid out on the bed.

“I will be back in 15 mins to collect you both,” Sir said, then headed to the lift of the penthouse, leaving Susan and me alone now.

Both outfits were very short PVC dresses with a high neck and cut-out holes where our breasts sat through, together with a white satin apron.

A black 6-strap suspender belt with black fishnet stockings. On the floor at each side were 6" high-heeled, open-toed, black shoes with an ankle strap which closed with a small padlock on the strap.

Susan came over to me and hugged me, whispering in my ear as she did so.

“Oh, you look so sexy, my little bitch, in that outfit.” She then gave me a quick kiss.

"We both look such whores for Sir, in these outfits, Susan, as that's what we are," I told her.

Susan just smiled as we then finished getting dressed.

Susan did look very sexy in her outfit. Her breasts were sticking through firm and pert, the hem of the skirt barely covering her ass. Her cunt will definitely show if she bends over.

Again, Susan came over to me, “God, Evelyn, you look so sexy," as she pinched each of my nipples in her fingers.

Again whispering in my ear, “I so hope I get to play with my bitch afterwards," smiling at me.

We then headed out into the lounge to await Sir's return, which was only a few minutes later.

“Mmmmmmmmm such perfect whores," as he looked us both all over.

He then came to me and clipped a leather collar around my neck. He then did the same to Susan. I could see that the collar had 'WHORE' written along the front, the O being a ring attached to the collar.

Sir then clipped a leash to our respective collars and led us by our leashes towards the lift.

“Time to head to the restaurant," Sir said.

Susan looked at me, puzzled, but I just smiled knowingly as we headed into the lift.

As we arrived at the restaurant, I could see that Susan was puzzled, wondering why Sir had brought us here.

As Sir helped us from the car, he walked in front, pulling both of us along behind him, by our leashes, as we entered the front door.

"Good evening, Sir, your table is ready and awaits you all," as we were greeted at the door.

Sir led us through the restaurant towards his normal table. When we reached the table, he told us both to kneel at the side, which we did immediately.

The restaurant now began to fill up, and I recognised some people from my previous visits here.

I saw Mistress Fiona take her seat beside another beautiful woman. She was wearing a black leather catsuit with red knee-high boots.

I had hoped that perhaps Sabrina would be here, but realised that Mistress Fiona was sitting at the table with other Doms/Dommes.

Once everyone was seated, Sir stood and spoke.

“Ladies and Gentlemen, thank you for coming tonight. As you are aware, this is a charity night, so please dig deep into your table's pockets." He paused while everyone clapped.

I noticed the table of young gentlemen who had used me on my first visit was present again. There was a table of women, and the Doms/Dommes table, where Mistress Fiona sat. Another table held several black men, but I didn't see any sign of Dan, which disappointed me for some reason.

Susan looked at me now, and I could see there was a mixture of both fear and excitement on her face.

I whispered to her, “It's okay, Susan, you will enjoy."

However, I knew that if the table of Doms/Dommes got Susan, then she might struggle to survive it.

Sir spoke to Susan, “Stand up whore." Susan did as she was ordered to and stood up in front of the room in her sexy maid's outfit.

“Ladies and Gentlemen, we have two whores tonight. Evelyn, you already know, and this here is Susan, my new whore" Sir told the audience.

“I will auction Susan first. Who will give me an offer for this delectable whore?" as Sir now started the auction.

Offers started to come from the tables, up to £5000 now. Susan's eyes widened at the amount to be paid for her.

Bids kept coming until Sir spoke.

“Do we have any other offers? We are now at £10,000, going once, twice, sold to table 8.”

I looked over Table 8. This was the table of females. I'm not sure this is what Susan expected, though.

“Okay, now for my other whore, Evelyn, who most of you know from here previously. Who will start the bids?" Sir asked the crowd.

“£20,000,” a shout came from one of the tables.

Susan looked at me in amazement.

Bids were now coming in fast.

“Okay, final chance, going once, going twice, sold to Table 3 for £ 45,000."

I couldn't believe it, and Susan just looked at me in shock.

Looking up, I could see that table three was Mistress Fiona's table.

It seems I was to be punished and probably severely. Maybe it was better for me than for Susan, I thought.

“Come and collect your whores." Sir announced to all.

 A member from each of the winning tables now approached and took hold of our leashes.
