Once upstairs, Mistress Fiona told me to change into my maid's outfit, as Sir wishes me to serve both her and Mistress Sabrina whilst they remain here.

I will be keeping the house, cooking for them, and also will service them sexually if they wish me to.

I therefore change into my black PVC maid's dress, with a white PVC apron, fishnet stockings, suspenders, and my 6" high heel shoes. I then make them both dinner, which they eat, and both compliment me on my cooking skills. Well, Mistress Sabrina is well aware of my cooking skills.

Mistress Fiona then speaks more seriously about Susan.

“Evelyn, we intend to break her will until she becomes completely submissive and accepts that will be her place in life going forward," she tells me.

“What she attempted to do to you, Evelyn, was serious. She must have been incredibly jealous of you, to wish to prise you away from Sir with the intention of pimping you out as a cheap common prostitute," as she put her arm around me.

“You choose to let the slut and whore, who was definitely so much a part of your natural self, out, Evelyn. Something that Sabrina here knew, but was scared of losing you because of it.

However, Sabrina confided in me that she knew she couldn't stop you pursuing this part of you, and in fact, your strength in doing so gave her the courage to also pursue the female side that was strong within her." She now tells me, as Sabrina just nods her agreement.

“What I’m saying is that doing what you have done shows that you are a beautiful, bright, determined girl. And now we have seen that you are clever with it and strong-willed." She praises me.

Then she emphasises her point, saying.

“EVELYN, YOU WILL NEVER EVER BE A COMMON CHEAP PROSTITUTE"

Sabrina holds my hands as she now speaks to me: “Mistress Fiona is right, Evelyn, you are the whore you've become because it's what YOU want, not what anyone else says, darling."

Mistress Fiona tells me I don't need to watch what they will do with Susan if I don't wish, but if I do, I should stay in the background.

“I'd like to be present,” I tell Mistress Fiona.

So after clearing up the dinner plates, we all head down into the Dungeon once more. Hearing us enter, Susan begins pleading to be set free. You can hear the fear in her voice now.

Nothing is said in reply as Mistress Sabrina just unchains Susan and takes her back to the St Andrews cross. Again with her back to it. However, the hood over her head is left on.

I stand well in the background, as I have been told to, and just watch both Mistress Fiona and Mistress Sabrina now, as they both pick up canes.

Without warning Susan, they begin caning her in turn. A whoosh of Sabrina's cane over Susan's breasts is followed by a whoosh of Fiona's cane over her thighs. They continue caning her in turn, as lines of welts now appear alongside the marks Mistress Fiona made earlier with her whip.

Susan is screaming with the pain, and tears once again stream down her cheeks. However, neither Mistress Sabrina nor Mistress Fiona let up, only changing their target areas so that Sabrina is now hitting Susan across her stomach as Fiona moves up to hit across her pussy mound and then over Susan's clit area and cunt lips.

This makes her scream even louder and sob so much as she is trying to beg for them to stop now. “P, please please stop, I'm so sorry," she manages to get out between her sobs and further screams of pain.

I have taken some punishments so far, but nothing seems even close to the severity that both Mistresses are dishing out to Susan now.

Then suddenly they stop.

Susan slumps forward on the cross.

Mistress Sabrina then uncuffs her and turns her around on the cross so that her back and ass are exposed.

Mistress Fiona then goes to a drawer in the dungeon and pulls out a big butt plug. I also see her take out what seems to be an egg toy.

She hands them to Sabrina, who takes some lube and applies it to both the plug and also to Susan's ass.

The butt plug is then pushed against Susan's hole, as Mistress Sabrina pushes and twists the plug until, with a scream of pain from Susan, her hole opens up and swallows it deep in her bowels.

Sabrina then shoves the egg in Susan's cunt.
Mistress Fiona then presses a remote, and the egg starts vibrating in Susan's cunt, making her moan. I’m not quite sure if it is moans of pleasure or pain.

Suddenly, she turns it off again.

Sabrina now goes to a drawer and comes back with a metal chastity belt, which she attaches and secures around Susan, so that the toys will remain in place.

Sabrina then undoes the cuffs and takes her back over to the wall and chains her up again.

Again, they don't remove the hood, leaving her, once more, deprived of any sight.

“Try and get what sleep you can bitch." Mistress Fiona tells Susan, “We will be back in the morning.”

The three of us then exit the dungeon, leaving Susan all alone in the darkness once more. Her whole body must be stinging like hell, I think to myself.

Mistress Fiona and Mistress Sabrina take turns during the night watching Susan on a monitor, as I discover Sir has cameras in the dungeon.

I am told it is mainly for situations like this, if anyone is bound and left, so that we can check they are okay.

It seems to me from this that even in such severe circumstances, Sir, and other true dominants, still care for the submissive.

I don't know if Susan slept much. I know I struggled to sleep that night, but I know she will have been woken at times throughout the night as both Mistress Fiona and Sabrina set off the vibrating egg in her cunt.

Normally, this will please any woman, but in the circumstances Susan now finds herself in, it is more a drain on her already exhausted body.

As morning comes, I wake up from the short sleep I finally manage, shower, and put on another of my maids' uniforms. This one is short and made from soft silk.

I then head into the lounge, and Mistress Sabrina is sitting on the sofa. I realise that she has swapped over with Mistress Fiona sometime during the night while monitoring Susan in the Dungeon.

“Good morning, Evelyn." Sabrina greets me, standing up to give me a hug and a kiss on my forehead.

“Good morning, Mistress Sabrina." I reply, smiling as I say those words.”Can I get you a coffee?" I ask.

“Oh, that would be great. Thank you, Evelyn." Then asks, no was more of an order befitting her new status.

“After that, make some milky Weetabix so I can feed the bitch downstairs and a plastic cup with some water." The firmness in Mistress Sabrina's voice seems to trigger a tingly feeling in my body.

I therefore make up the cereal, as ordered, pour some water into a plastic cup, carry the tray, and follow Mistress Sabrina down into the dungeon.

Mistress Sabrina tells me to feed Susan, which I try to do; however, she struggles to swallow. I then allow her to drink some water through a straw.

Once she can’t take any more, we leave her again in the darkness as we head back upstairs.

Mistress Fiona is now up. “Good morning, Mistress Fiona," I say, greeting her warmly.

“Thank you, Evelyn. Good morning. Did you sleep?" she asks.

“Not much, Mistress Fiona. I seemed to toss and turn all night," I respond.

“Understandable in circumstances. Well, go make us all some breakfast as we need to keep up our strength," she tells me.

I busy myself making breakfast, which we eat together, all sitting around the kitchen table.

Mistress Fiona speaks mainly to Mistress Sabrina, but allows me to listen in.

“Susan will be allowed rest today, but remain chained up. She is heavily bruised and marked, so to inflict more punishment could cause permanent damage to her, and that isn't our objective." Asks if we understand that, which Mistresses Sabrina and I confirm we do.

“However, Sabrina, I want you to find the set of vibrating chains and clamps that Sir has in the dungeon; they will be in one of the drawers downstairs." Mistress Fiona says to her.

“Attach a clamp to both nipples and also to her clit. Today, whilst not being punished, she will be kept on the brink of an orgasm, but we always stop before she orgasms," she tells Sabrina.

Mistress Sabrina leaves to head down to the dungeon to carry out the instructions she has been given.

“Are you okay, Evelyn?" Mistress Fiona asks as she puts an arm around my shoulder.

“I know this will be hard on you, especially as you thought that Susan was a good friend."

“Yes, Mistress Fiona, I realise that we all have to know that there will be consequences to our actions, be they good or bad. Susan betrayed the trust I thought we had," I tell her.

Thursday will be a long day, I feel.

Susan is subjected to vibrations that run through her body from various items that are either inside or clamped to her body at regular intervals.

One minute she moans in pleasure, then the next squeals in pain.

This only stops to allow Susan to either eat or drink water.

Susan is kept hooded at all times and is completely disoriented, even unaware of what day it is.

After Susan is fed some dinner, in liquid form, she is again subjected to bouts of vibrations that shoot through her body throughout the evening.

However, late at night before bed, we all head back to the dungeon. Susan is taken and again strapped to the St Andrew's cross.

Both Mistress Fiona and Mistress Sabrina begin to whip Susan once more, across her back, her ass, and her thighs.

This goes on for a good half hour, leaving Susan with more marks on top of her existing marks.

Mistress Fiona speaks to Susan, “Who are you?"

“I'm Susan," she says defiantly.

I hear her scream as Mistress Fiona whips her back ferociously, “Wrong answer."

Again, Fiona asks, “Who are you?"

“I'm Susan," again she says

More screams as she feels the whip crack over her back.

“Who are you, what are you?" Mistress Fiona now asks.

“Bitch, I'm a Bitch." Susan shouts out loudly.

Mistress Fiona smiles, and Mistress Sabrina uncuffs Susan, taking her back and chaining her to the wall again, leaving her once more overnight in complete darkness.

I am exhausted from the lack of sleep the previous night, and as soon as I lie in bed, I fall asleep quickly.
