Tracey was late for the next session, so Amy and I started work without her. I left my old painting shirt on, just in case she eventually turned up, but that was starting to look very unlikely. We had finally come to the conclusion that Tracey didn't want to do any more nude modelling, even though it was a golden opportunity for her to get close to Amy with no clothes on, when in she walked.
"Sorry I'm late," she said. "Do you still want me?"
"Of course", I replied, "we're glad you could make it."
She stood in the doorway, not quite sure what to do next. She didn't have Amy's easy confidence about being nude in front of strangers, and Amy sensed this. She had been lying on her back on the dais, but she quickly swung her feet to the floor and walked naked over to the doorway, taking Tracey by the hand and leading her into the studio.
"You can put your bag down, you know. We won't steal it", said Amy.
Tracey had been clutching the strap of her shoulder bag very tightly, but she smiled and put the bag down beside the dais. Without asking her permission, Amy undid the buttons of Tracey's coat, slipped it off her shoulders, and handed it to me. I put it on the coat rack near the door, while Amy undid Tracey's jeans. Tracey was now helping the undressing process and lifted her top up and over her head, tossing it behind her. When Amy squatted on her haunches to pull Tracey's jeans down to her ankles, Tracey slipped her hands inside her thong panties and pushed them down, too. Her pussy was now as bald as Amy's, and Amy whistled when she saw it.
"When did that happen, Trace? Nice looking job", she said appreciatively.
"That's why I'm late. It took longer than I thought it would."
"I would have helped you," said Amy, sounding a little disappointed. "That was the plan."
"I know, but I felt more comfortable doing it myself. It's a very personal thing to do, you know."
"Oh, I know," said Amy, "That's what makes it so much fun when someone else does it for you."
"Yeah, well. I wanted to do it on my own," said Tracey. "At least the first time."
"May I?" said Amy, not waiting for permission, but reaching out immediately and feeling the skin all round Tracey's pussy. At first it was obvious she was checking the smoothness of the shave, but her fingers lingered as she felt for stray hairs round the opening to Tracey's vagina, and when her middle finger disappeared and she murmured "Nice", it was no longer clear whether she was still referring to the quality of the shave, or the feel of what had just been shaved.
I cleared my throat, to get Amy's attention. "Are you two ready to do some work?"
Tracey had been engrossed in what Amy's fingers were doing, but jumped at the sound of my voice, like I had caught her with her hand in the cookie jar. Amy shot me a dirty look, to let me know that she didn't think I needed to be such a killjoy, then, for Tracey's benefit, tried to sound enthusiastic.
"Sure. What do you want us to do?"
"I think it would be nice to get the two of you lying down, entwined, all tangled up in each other so I can't see whose arms and legs are which. Can you do that?"
It took a minute or so to get some big cushions onto the dais, and to throw a brightly coloured piece of African fabric over the whole thing. I wanted them to get comfortable, because I thought that what I had asked for would be visually very interesting, and I was prepared to spend a bit of time trying to get a decent result from it.
I had imagined them cuddling somehow face to face, with their legs wrapped up and round each other's body, but when Tracey swung herself onto the dais, Amy walked round to the opposite side and laid herself down in the opposite direction, so her legs would be up and around Tracey's shoulders, and vice versa. OK, I thought, this could be even better.
Amy lifted Tracey's leg over her shoulder as she lay down, resting her head on the inner thigh of Tracey's lower leg, her face only about a foot away from the light pink pussy. She wrapped one of her legs over and around Tracey, whose hand was now resting on Amy's buttock, her trunk twisted and leaning back. Tracey's head and shoulders were a little further away from Amy's pussy, but she was still able to look straight at it, and it was still very accessible to her.
"That looks... interesting," I said, taking a piece of thick vine charcoal and quickly blocking out the main shapes the two young women made.
"It looks pretty good from here," said Amy, looking straight at Tracey's open crotch.
"The view's not bad from this end either," said Tracey, obviously starting to relax and lose what was left of her inhibitions.
I had a feeling that neither of them would be able to hold this pose for long, and I was right. It wasn't that it was awkward, on the contrary, they were both nestled in very comfortable positions over and around the big cushions. But I knew from what Amy had said about her preference for women that Tracey would surely be getting very turned on by the closeness of her naked friend, and I knew that Amy's bisexual curiosity and her love of exposing herself would be having a similar effect on her. It seemed that every time I made some marks with the charcoal, and then glanced up from the paper at my models, Amy's head looked like it was just a fraction closer to Tracey's pussy, and Tracey's hand looked like it was sliding slowly down Amy's ass crack towards Amy's. I quickly realised that it was not my imagination and the two models were not holding themselves as still as I wanted them to be. I tried to draw more rapidly while I still had a chance, but I would have had to be a lightning sketch artist to have captured the pose before it completely disintegrated. Within minutes, Amy's face was within a tongue's length from her friend's pink and glistening pussy, and she was breathing in deeply through her nose, savouring the scent of its slippery wetness.
"Hang on, Amy, I'm not finished drawing yet," I said.
"Sorry, Sam, your needs aren't my highest priority at the moment. And I think you should know that this cunt smells sinfully tasty."
"That's more than I needed to know, girl, I'm trying to concentrate here."
"Me too," said Amy, as she closed her eyes and moved her head the last few millimetres towards the source of the olfactory stimulation. Just before her open mouth locked itself onto Tracey's pubic mound, I caught a glimpse of Amy's pointed tongue sliding into the already wet vaginal opening.
