A buzz from the intercom. It's Jaan, down at the front door. (I will tell you more about my lovely Jaan a bit later.)

His voice is deep, resonant, respectful but with a twinkle of humour too.

"Sylvia, your guests have arrived."

"Thank you, Jaan. Would you please offer them a drink? I need ten minutes."

The guests are early, eager perhaps? I smooth my dress and check my make-up, and then I put on my mask. A face-covering is an essential feature of my work. I must never allow myself to be recognised.

The mask is black and lacey to match my lingerie. It's sufficient to conceal my identity but leaves my nose and mouth exposed. 

I take one last look around the room. I like to begin with the room brightly lit. Softer lighting comes later once everyone is settled.

A pee, a wipe, a wash of the hands, and now I am ready to receive my unknown visitors.

Interestingly, after all this time in Amsterdam, I still feel anxious at this point. I feel perfectly safe with Jaan close at hand, but it sometimes takes a while to relax inexperienced guests.

I press the buzzer, and Jaan picks up the phone immediately.

"Send 'em up, Jaan!"

"They are on their way, Madam!"

Now there will be a pause as the guests finish their drinks. Then Jaan will show them to the elevator, and I will hear the rattle of the ancient machinery as it clanks and squeals. 

My home consists of the top two floors of an ancient house on the Keizersgracht. Right at the top, under the eves, is where I sleep and live the everyday life of an Amsterdammer. There's a tiny kitchen, a good-sized bathroom, and my bedroom faces East and some mornings, the sun simply pours in.

In case you are wondering, I live alone here. But I do have girlfriends, no one 'special'. I know that will happen one day, and meanwhile, I am busy with my work.

I hear the elevator doors slam shut, and the cage ascends. I take a deep breath and let it out slowly. My kind of work is not for the faint-hearted.

There's a metallic clatter as the elevator arrives, and it's showtime!

I step out into the hallway in readiness. As the elevator grill slides back, I stand back a little, half-hidden by the lighting. It all adds to the 'moment'.

"Welcome. My name is Sylvia." I say brightly, holding out my hand. Two women emerge from the elevator. Both are wearing hooded gowns that conceal their faces in the semi-darkness.

The gowns are all part of the mystique of this place and the exclusive services I provide. Some regular guests possess their own, and newcomers are supplied with something suitable by Jaan as they arrive,

So, two women. one seems mature, the other young. The elder of the two takes my hand.

"My name is Elena. May I introduce my partner Sophia."

I take the younger girl's hand and give it an affectionate squeeze.

"Please come inside and make yourselves comfortable," I say.

 I stand aside and let them enter the room first.

It's a crucial moment. I must allow time for my guests to acclimatise to their surroundings. 

"It's so beautiful here," murmured Elena. 

"Thank you. It is an extraordinary place, is it not?"

I am trying to give the impression that I am just as much a stranger here as they are. Now the moment arrives where I must assume control.

 In a slow, deliberate voice, I say.

"If you wish, you may remove your gowns and reveal yourselves."

Elena is the first to throw back her hood and unfasten her gown. She lets it fall to the floor.

Elena is an attractive woman in her late forties but with a youthful spirit. Tall and shapely and beautifully dressed, confident and poised.

FUCK... it's my fucking MOTHER!

I turn away, gripped the edge of the table. Inside, I am screaming.

Struggling to compose myself, I turn back, relying on my mask to conceal my reaction. 

Now Sophia shrugs back her hood and, as her hands move to unfasten the gown, I realise 'Sophia' is my younger sister.

With alarm bells clamouring in my head, I say the first thing that comes into my head.

"Let's have some champagne?"

Without waiting for a response, I buzz down to Jaan.

As usual, he answered immediately. 

"Champagne Sylvia?"

"Thank you, Jaan."

"Is everything okay, Sylvia?"

"Oh yes, very okay thank you, Jaan."

Jaan had detected the tremor in my voice because I am still reeling from the shock of providing sexual services to my own family!

Jaan has been like a father to me. I feel safe and protected when he's around, and he has an instinct about my guests. My lovely Jaan will have checked over anyone entering that elevator. 

I need to fill in some details here. You see, I left home a long time ago to escape my father. I haven't seen any of my family for about twelve years.

So by now, my sister would be about eighteen, and here she is so lovely. Slim, leggy, and so pretty. And my mother? How she suffered. My father was brutal to her. My sister and I used to hide in the cupboard under the stairs while it was happening.

At last, a knock at the door. Jaan is here and brings me quickly back to the here and now.

He brings in two bottles of champagne, a giant ice bucket, and three glasses. Then, with a great show of dignity, he opens the bottle, fills our glasses, buries the bottle in the ice bucket, and leaves the room with a slight bow. 

Before closing the door, he pauses and looks directly at me and raises an eyebrow. I nod to acknowledge his unspoke question and to let him know that I have the situation just about under control.

My guests are settled now. I have overcome my shock and am now turning to my professionalism to sustain me through the next episode.

"So." There's a single word that is required at this point. It eloquently signifies when my clients need to reveal their desires, their reasons for investing so much money in my services.

And so, placing my hands on my knees and looking directly at 'Elena'

"So... "

There is no hesitation as my mother turns to her daughter and puts a hand on her shoulder.

"Sylvia, I want to watch you fuck Sophia's brains out."

And, without missing a beat, I reply, "It would be my pleasure. Elena." 

Now I need to check because every client's free consent is paramount here. I reach down to kiss my sister's lips.

"Sophia, is this what you had in mind too?" I whisper.

Sophia looks up at me, her brown eyes wide, her pupils dilated. 

"Yes, Sylvia, you can do whatever you want to me."

No more words are necessary. I smile reassuringly at my little sister and lead her into the bedroom and the candlelight.

Elena follows and settles herself on a pile of cushions.

And so it begins.

I lead the girl to a massive wall mirror, and now Sophia is facing her own reflection, barely a metre away. She is so lovely. Over the years, she has grown into a beautiful young woman.

Sophia stands perfectly and lets me unfastened the buttons at the back of her dress. The soft silk from her shoulders falls to her waist and drapes from her hips. Her petite breasts need no additional support, and now Sophia is topless.

I can see Sophia looking critically at herself. I note that her beautiful coral pink nipples are slightly inverted.

I slide her panties down, let her step out of them. Next, the hold-up stocking and heels and Sophia is utterly naked.

I look back at Elena. Her eyes are narrow slits as she gazes intensely at her daughter's naked body.

While the girl continues to stand facing the mirror, I caress her back, flanks, and, finally, her beautifully formed bottom. I feel her body respond as I reach round to touch the blonde tuft of pubic hair. I hear a gasp as I slide my hand between her legs and feel the heat of her sex and its wetness.

I turn Sophia around to face me, and I suck each nipple in turn, so each comes erect. They are so deliciously beautiful. Then, in a sudden and spontaneous gesture, Sophia put her arms around my neck and kisses me with shocking passion.

Now is the time to act. I lead my sister to the bed and position her to sit astride the corner of the bed. Piling pillows behind her back, I make sure she is comfortable. She watches as I strip. I don't make a song and dance about it. Quickly and efficiently, I take all my clothes off.

Kneeling now and with my hands on her knees, I smile up at Sophia, just to make sure this is really what she wants. The look on her face tells me everything, and so I bury my face between her legs and begin.

As a professional, I reveal no preference for whatever sex act I am requested to provide, but licking a fresh young pussy is definitely at the top of my list.

My sister's delicate velvety folds are deliciously warm and wet, and I love how she is pushing herself against my mouth. So I slip my hands under her bottom to bring her even closer to my tongue. God, the taste of her! 

Sophia's first orgasm comes surprisingly quickly. She stifles a scream, and her slim young body quivers in my arms. I move on to the bed and hold her close. 

Looking back at Elena, I see that she has pulled her dress up around her waist and is openly touching, her face flushed red.

Before Sophia has a chance to recover fully, I slide two fingers into her vagina and press them deep. She responds beautifully, pushing back against my hand. My thumb works her clitoris as I set up a gentle rhythm.

Now my little sister's journey has truly begun. Her uninhibited moaning is delightful as I pump my fingers into her, deep and hard.

The way I am circling Sophia's clit seems to be working for her. (I often use the same technique myself). 

Now we are working together beautifully. Sophia lifts her hips, and I work a third finger into her. God, she is hot! I don't always get to enjoy my professional encounters, but this time is different!

Sophia comes again, unexpectedly. A jolt of electricity. Her back arches, she clutches at her breasts and simply howls.

Without missing a beat, I withdraw my fingers. My sister looks at me in alarm. Then she sees me fold my thumb into the palm of my hand so that my fingers form a cone, and I push it slowly, gradually into her wet, open cunt, and she yields with a gasp.

Now we are working as one. Sophia is now entirely the possession of her own body, her own lust. She has no will of her own, and she must obey the demands of her sexuality.

As I pump, deep and hard, Sophia pushes back with equal force. Our rhythm quickly establishes itself, and now we are both lost in our lust for each other.

I know she is close now. Her arms are flung wide in a gesture of total surrender. With a deep-throated growl, Sophia reaches her climax. Although she is writhing and screaming, I do not relent. Mindful of Elena's brief, I press on.

There is another orgasm hiding behind this one, in all its torrid extravagance. I know this, and I pursue it with dogged determination.

Sliding my middle finger into her anus achieves my aim, and Sophia howls as her final orgasm rips through her.

As Sophia curls into a foetal position, I stroke her hair and whisper my praise and my thanks.

My job probably sounds sexy and exciting, but it carries enormous responsibilities. I work with my clients in extremis. They are often beyond reason in their exquisite ecstasy, and I have a duty of care.

Now I can turn my attention to Elena, to my mother. Her face is flushed, and she is very sexually aroused. Her panties have been discarded, and she is openly touching herself.

Our eyes meet. Something from my past triggers my feelings now.

"Sylvia, fuck her again!"

"I think she has had enough, Elena."

"I decide when she has had enough!" Elena snapped back.

"That's not how it works here, Elena."

"So, how does it work, Sylvia?" Elena replied aggressively.

"Please allow me to show you, Elena."

I looked at her directly. It was time for me to assert myself before things get tricky.

I saw the look on her face, and I knew what I had to do.

"Get undressed!"

I saw the look of surprise on her face. 

"Get undressed?" She asked as if this was an outrageous suggestion.

(It's often the case that clients assume they are the ones who are entitled to have control. Not on my watch!)

"That's right, Elena, take your clothes off!"

I saw her face change as she realised this was not a sex game in which she automatically held the upper hand.

"Kneel up on the bed and wait for me... "

I made sure that she had understood her instructions and had begun to undress, and I went into the adjoining room.

With Sophia fast asleep, safe in my bed, I can afford to take my time.

Opening the cupboard, I selected my favourite strap-on harness. In real life, it's all about comfort rather than style. I'm not making a porn movie. I am getting ready to fuck my own mother.

There is a shop near where I work, where they understand these things. It's pricey, but it matters. With a strap-on, I need to feel something too. So a secure location, nice and snug against my clit is so essential.

Actually, I'm not fond of realistic penis replicas. What I am about to do has nothing to do with men and the way they are made. I am a lesbian, and I fuck like a lesbian.

When I emerge from my room, I am fully equipped. The dildo I have chosen is all ridges, has nodules and a bulbous tip. 

I am pleased to see that Elena is naked and she is lying flat on her front. 

Elena knows what is about to happen, and as soon as I touch her, she lifts her bottom. 

Elena hides her face in the pillow. Is this her first time, I wonder?

I squeeze the lube over the dildo and then work some in and around her anus. Elena seems to be accepting this without response. She is in for a shock.

"Can you feel the pressure?" I ask as the dildo's tip pressed against her star. 

Now I push deep, and the response comes, loud and clear. A guttural scream as Elena feels each ridge make her anus flicker as I slowly slide deep into her bowels. 

The dildo is only about seven inches long, but it feels a lot longer once it's entirely inside. I like to enter fast but withdraw very slowly. I love seeing how the rim stretches and is released as each ridge and nodule passes through.

They say that the anus has just as many nerve endings as the clitoris. In other words, it also is designed for pleasure!

Back to business, and it clearly is NOT Elena's first time. The way she is pushing back against me and her moans and the way I can feel her tensing her muscles around the shaft.

I am beginning to wonder if she might even cum this way. But I see how she is reaching under and rubbing her clitoris. A genuine anal orgasm is rare, in my experience, but usually, there's so much going on down there that it doesn't really matter.

And so it was with Elena, my mother.

I had been fucking her hard. It brought me no pleasure, but her scream was unmistakable. I felt her pulsating contractions grip the dildo as I went as deep as I could.

Whilst I am relatively unaroused, I'm thrilled that I have brought Elena to her climax. It's what I do professionally, pretty much what people are paying me for.

As Elena's spasms diminish and her cries turn to whimpers, I slowly withdraw the dildo from her gaping anus. I love to watch the ring of muscle flicker as the dildo's ridges draw out that little collar of skin.

Elena, spent now, lays face down on my bed. I sit back on my haunches and unstrap the harness. I am pleased with my 'handiwork'. Now I am wondering what will come next.

I don't have to wait long. As I sat back, I felt something cool sliding down my back. I turn, and it is Sophia. She is holding one of my most prized possessions, a riding crop bound in red leather. The shaft is fiberglass, and it produces the most beautiful welts on tender young bottoms.

As our eyes meet, I understand what Sophia has in mind. We both look down at Elena's freshly fucked arse. So I slide back, and Sophia, still naked, brings the crop down hard on her mother's bare buttocks.

Elena, who up to now had been lying face-down quietly whimpering, screams out in shock and pain. I am shocked too, shocked by the force of Sophia's blow but shocked too by my own reaction.

I am instantly aroused, more so than I can ever remember. Trying to maintain my professional poise is hopeless. I look up at Sophia, and I see the naked lust in her eyes. She strikes again. Elena screams but makes no attempt to protect herself.

Still kneeling on the bed, I have one hand between my legs and the other clutching at my breasts.

Sophia strikes again and again, and the livid welts criss-cross Elena's bottom. Jaan can hear the screams, but as long as it's not me that's screaming, he will not intervene.

Sophia drops the crop, turns, and kisses me. I know that she knows; it was how we kissed when we were hiding from our horrible father, and my orgasm came straight away, just as it did then.

Now it was Elena's turn, her face flushed...
