Hi, my name is Emily and I'm 23. My sex life is... Complicated. I'm bisexual and normally extremely submissive with male partners and dominant with female ones. It's not cast in stone, or even a rule; for example there was Claire.

I met Claire when my family bought me a professional photo shoot for my birthday. It was my first one, so I wasn't sure what to expect. I prepared for it like I was going on a date; after all I wanted to look my best in the photos. The day before my session, I had a haircut followed by getting my eyebrows done, then a facial and finally a full wax.

On the day itself I wore a pristine white lingerie set under a tight, dark blue satin off the shoulder formal dress. I also took a couple of outfit changes with me - the classic little black dress (with an emphasis on little), plus a short skirt and white blouse I use for "schoolgirl" dress-up sessions.

When I arrived, the reception desk was empty and I stood there self consciously for several minutes before I noticed the bell tucked away in the corner. I rang it, and seconds later Claire appeared. She was young, barely older than me, and she was hot!

She wasn't wearing anything that you'd call sexy, just a pair of black cargo trousers and a light grey t-shirt, but somehow she made those clothes look good. The t-shirt was tight across her chest, the trousers equally were gripping her hips, but that wasn't it. It was something about the way she stood, the slight tilt of her head as she smiled at me.

I realised I'd been staring at her silently for far too long.

"Hi, I'm Emily. I've got a 2pm appointment Do you work here?" She let out a short laugh and replied "Work here? I am here!" another quick laugh "I'm Claire and I'll be your photographer today" Even her voice was attractive - and she was clearly talented too. I know how hard it is to run your own business, let alone one as competitive as photography. I was so embarrassed to have misunderstood, but she quickly waved my apologies away and led me through to her studio.

It was a windowless white room, and at first glance it seemed to be overly cluttered with furniture and strange equipment but as Claire pointed various things out, I realised it was an organised chaos. One side held a chair, bed and other furniture to pose on, another side held a curtain rail to quickly change backgrounds, while a third had a screen to get changed behind and rails to hang clothes on. Scattered throughout were lights and reflective umbrellas, and in the very centre stood a stepladder of all things. Claire saw me looking at it and quickly explained "sometimes it helps to look from a different angle".

She led me over to the curtain rail and quickly sorted through before choosing a creamy yellow. Claire picked up a camera and said "the most important thing is for you to be comfortable. I'll get the best shots when you're relaxed. I'll just start with a few warmup pictures" and before I knew it I was dazzled by a flash that seemed to come from everywhere all at once.

She kept talking and taking pictures and I did feel myself start to relax. I got so accustomed to the flash that I quickly stopped noticing it at all. When she started suggesting I hold my arms in a certain position, or look in a particular direction I obeyed without a second's thought, until she suggested a pose I couldn't seem to get just right.

She put the camera down and walked up to me asking "may I?" I just nodded, secretly a little relieved. She moved my arms with the faintest of pressures, her fingertips barely brushing my chin as she tilted my head to just the right angle. When she stood behind me and brushed her hands across my stomach and thighs to straighten out my dress, it felt almost sensual and I had to concentrate not to move from how she had placed me.

A few more pictures later, she commented "I saw you brought some other outfits, do you want to change into one of those?" I agreed and stepped behind the screen to change. I don't know why, but I chose the faux schoolgirl costume, and as usual when I wore it, I tied the bottom together to expose my midriff and left the top two buttons undone.

When I stepped out from behind the screen, Claire took one look and said "There's only one setting for clothes like that" and pointed to the bed. I nodded. For some reason my mouth suddenly felt dry and I wasn't sure I could speak. Did I mention how hot she was?

To start with, she had me sitting on the edge of the bed, knees pressed together and hands primly in my lap, but as she kept giving instructions and taking photos, it wasn't long before I was laying sprawled out on the bed. I knew the short skirt was riding even further up my thighs but I was so caught up in the moment I didn't give it a second's thought.

It wasn't until I was halfway through undoing the last buttons on my blouse when realisation hit me, and I paused. I'd brought this outfit to have some risqué pictures taken, but did I really want to go that far? Claire noticed my hesitation and smiled reassuringly. "Would it help if I took mine off?" I must have nodded, because the next thing I knew she was standing in front of me topless apart from a black lace bra. She nodded in encouragement and I returned to undoing the buttons, my fingers fumbling slightly as the camera continued to flash.

Claire looked meaningfully at my skirt and I blushed. A part of me was scared, but there was a bigger, more vocal part of me that was enjoying it. "you first" I said, barely above a whisper. She laughed "I don't usually do this for my clients, but you? I like you!" Claire kicked off her shoes and the socks and trousers quickly followed. For some reason I fixated on the fact that her pale pink panties didn't match her bra. "Your turn" she said, and I realised I'd been staring again. Before I could think twice, I stood up, pulled the zip and let the skirt fall to the floor. Another series of pictures followed, with Claire putting me in some very compromising positions. I felt myself growing steadily more aroused as I all but exposed myself to a virtual stranger.

At the end, she was laying on the bed with me, kneeling above my head and taking point of view shots of my body. I looked at her and a wicked smile came to her lips as she said "and what about this?" while plucking at my bra. I paused for a moment, then nodded. Both of us took them off at the same time. Her breasts were... Magnificent doesn't do them justice. Perfectly rounded, with bright pink areolas and topped with cute little nipples.

I was staring again, but Claire didn't seem to mind, particularly since she was looking at me in just the same way. Eventually, after what felt like hours but was probably only seconds, she broke the silence "wow! They're perfect! May I?" I tried to speak. I wanted to speak, to tell her that her breasts were far more wondrous than mine, but when I opened my mouth, nothing came out.

Instead, I reached across and cupped her breasts with my hands, feeling the softness of her skin, the firmness that lay just beneath. I ran my thumbs lightly over her nipples and heard her gasp, whether in surprise or pleasure I couldn't say, but she leant forward into me in response, and then her hands were on me. Caressing and stroking as she guided me down onto my back with a gentle but insistent pressure.

Claire took my hands from her breasts, moving them up above my head and holding them in place as her lips dropped closer and closer to my nipple. The touch of her tongue sent a shiver running through me and I couldn't help moaning as she licked and sucked first one and then the other.

I realised my hips were thrusting upwards in time with her licks, my pussy searching for the contact and release she so desperately craved. It seemed that Claire had noticed too. She let go of my hands and ran her fingertips lightly down my sides.

She rested her hand against my wet panties and my body took over, my hips rising to grind my clit against her palm. I was moaning nearly constantly and felt my orgasm building rapidly. I'd never before cum so quickly and from so little stimulation. And I still didn't. Moments before I reached my peak, Claire pulled her hand away!

I was whimpering in frustration, my hips still thrusting wildly into thin air seeking the final contact that would push me over the edge. "Patience my sweet" Claire said with a laugh. To my complete shock, she actually got up from the bed and picked up her camera "let me see how hungry you really are"

I wasn't thinking clearly by this stage. I pulled my panties to one side, exposing my pussy to her and her camera and reached down with my other hand to rub myself to completion. "No touching!" Claire ordered. I whimpered again, but the idea of disobeying never even entered my head. Claire had me pose for her, displaying myself from every angle and finishing on my knees facing away from her with my knees spread wide.

I felt her fingers brush my clit and pushed back onto her. Immediately she took them away again. Again she touched me, again I responded and again she pulled away. The third time, I tensed myself and held still as she stroked me. "Good" she said, gradually increasing speed. I felt my orgasm building to a crescendo again and tried my best to keep still, but at the last moment my body betrayed me, and her touch was gone.

I felt Claire gently roll me onto my back, and through the tears of frustration that had sprung to my eyes I saw that she had removed her panties at some point. She wasn't completely waxed like me, but had a little triangle of public hair, pointing downwards, as if giving directions. I honestly think that at that moment I would have done literally anything to be allowed to cum, so when she knelt astride me I didn't hesitate.

I sent my tongue over her clit, into her tight wet hole, I even licked her ass when she pushed herself forward. I heard her calling me a "greedy little slut" and I didn't mind at all. In fact it seemed like the perfect description for my behaviour. I heard her moans grow louder as she continued to grind against my face and I continued to lick and suck any part of her my mouth could reach.

Then the most wonderful thing happened - I felt her fingers rubbing over my clit. My cries of ecstacy were muted by her pussy as I squired for the first time ever. My orgasm was more intense than any I'd experienced before and I may even have blacked out for a few seconds. The next I remember is Claire kneeling over me, her pussy pressed against my lips while she rubbed her clit with fingers dripping with my juices. It wasn't long before my tongue and her fingers did their magic and she reached a shuddering orgasm of her own.

After we came back to earth and got dressed, in between kisses, cuddles and random small talk, Claire handed me a slip of paper with her home address on it. "Why don't you come see me tomorrow night? I'll have your photos saved and ready to pick up by then." That was the start of an incredible 6 month relationship, that taught me so much about lust, desire and submission. But perhaps that's a story for another time?
