"No men?"

"Nope, no men."

"No cocks?"

"None!"

I sat cross-legged on my sister's bed as she lay propped up on a massive mound of pillows, looking gorgeous even at this time of the morning.

"What about the cameraman?"

"Woman."

"And who will tell me what to do?"

"That will be Justyna. She's the director, and often she's behind the camera too."

My sister is called Helen and works as a glamour model and has been in lots of sexy videos and photoshoots. She calls herself Olivia North. That's her stage name, and she only works with other women making lesbian videos.

"And you get to travel to wonderful places and stay in beautiful hotels," Helen said.

"But you are much better looking than me, and cute and a lovely figure and everything... "

"Don't be silly, darling. You've got a terrific bod!"

Perhaps I should tell you that my sister and I have sex with each other. There I've said it. When she's home, we sleep together and do everything that lovers do. Please don't be shocked. I'm sure it happens a lot.

Our mum knows and is quite relaxed about it. Dad left here when he found out she was having an affair with another woman. There's a lot more to tell, but I don't know you well enough to put in writing here!

"And you get to keep the clothes and shoes, and the money is perfect too."

I feel myself warming to the idea. I have seen all of Helen's videos, and they are very gentle and loving, and everyone looks fabulous. 

"It can be a bit boring," Helen said. "There's a lot of waiting around between takes, but the other girls are fun, and we have a lot of laughs."

"Do I have to memorise a script? I would be hopeless at that."

Helen beckoned me, and I lay beside her, and she put her arms around me and kissed my ear.

"Let me tell you how this works, Kate." (That's my name, by the way. Not 'Katie', just Kate.)

And as big Sis cuddled me, she described how everything was done. It all sounded like the most incredible sexy fun. Justyna chose the models based on an idea she has in her head. Then everyone gets together, and the story is worked out collaboratively. That way, everyone is involved and has a distinct role to play.

At this point, I freed myself from her arms and took off my PJs and slipped into bed beside her. 

"Go on... "

"Once everyone is happy, then we rehearse. It's all improvised. Justyna wants it to appear spontaneous and natural."

"Does Justyna just make lesbian vids?"

"Yes. She trained as a filmmaker back home in the Czech Republic. She knows just about everything about films. She takes a few of us to the cinema sometimes to see films that she likes. They are usually very mysterious and very Russian!"

Helen was older than me. Three years older. I was just eighteen, so now I was legally allowed to appear in porn films.

"Okay! Sold," I said, and I felt Helen's hand cupping my pussy, and there were no more questions. No actual words were spoken for quite a while, but we were far from silent.

Downstairs, our mother smiled to herself and, seemingly absentmindedly, slid a hand down the front of her sweatpants as she recalled her sessions with her elder daughter.

Helen pressed the buzzer, and there was a loud click, and the door opened. We are in a part of London called Soho. It is the home of filmmaking and all the crafts and businesses that go with it. A shabby staircase as we climb up to the second floor. Another door and another buzzer, and at last, we are in Justyna's tiny office.

"Hi, Helen, and this must be your lovely sister!" 

Justyna was ever so nice. She had a lovely Eastern European accent and was very beautiful with shoulder-length blonde hair, and she was tall and slim and everything.

We all sat down on squashy beanbags. They seemed to be the only furniture in the room. I guessed that this was where the group discussions happened.

Justyna explained the purpose of the meeting. If I were willing, I would be given a screen test. A short video would be made, which would help Justyna see if I would be suitable.

Helen smiled at me as Justyna took my hand, and led me from the meeting room and down a corridor and into a room with all lights and cameras, a funny looking chair, and it was very bright and clean. And there was another girl there.

"Kate, this is Zoe. She edits all our films."

"Okay, Zoe... off you go, and Kate darling, let me explain what we are going to do."

Busy with her phone and all comfy on her beanbag, Helen had lost all track of time, so when I returned, dressed in nothing but a scanty little silk kimono, Helen was lost for a moment. Then she saw my flushed face and neck and my overall 'glow'. Justyna was also kimono-clad and a little breathless.

"Helen, darling. Your sister passed with all her colours flying." She said.

"But now we wait for Zoe to make the edit, and then we watch."

I was still flying, all my colours and everything! I have NEVER come like that before. I have always got off on being watched but being filmed took everything to another level. Justyna made me feel so relaxed and praised me until I didn't need encouragement anymore and began taking bigger and bigger risks.

I never expected to cum as quickly and efficiently as that. Justyna filmed me undressing. She said she didn't want a strip-tease. I was to undress as if YOU were watching. Then I was to sit in the weird-looking chair. It was actually very comfortable, and I could spread my legs, and Justyna could see everything down there. I masturbated, but Justyna stopped me before I came, and she put down the camera and undressed and licked me and then I came almost at once.

Then Justyna filmed me as I went down on her. She was lovely, and I could have gone on all day, but it was time for the film to be edited once she'd had her climax.

Babicka is a vodka made in the Czech Republic. It is infused with wormwood, it said on the bottle. We are doing shots. The edited video is here, and we are all drinking, and Justyna teaches us how to say  Na zdraví before every shot, and now the video is starting.

Helen came and sat with me. And as I watched, she was touching me, and I looked so beautiful, and I had never seen myself so close up before. 

I mean my pussy, my vulva, my cunt and my face. Fuck, I never knew how I looked when I was in orgasm.

Justyna was incredible, how she moved her body and how she let me do things to her too.

Now Zoe was back, and she quickly settled into the rhythm of what was going on and soon, the meeting room was a fragrant turmoil of bare bodies and the lovely liquid sounds of women loving each other.

I have no idea how we made it home. The vodka was powerful stuff, and I was so excited, and Helen was too, cos Justyna had decided to cast us together, and she wanted to film it in our own home so that it was completely natural and everything.
