For as long as I can remember, my wife has wanted to be a model of some kind.. This dream passed her by in her teen years, and once she entered the "rat race" it looked as if her dream was set to become a thing of the past.. That was until one afternoon when we were out shopping, passed by an adult shop and popped in for a look. After picking out a new lacey bra & panty set, we set off to the till to pay - and there it was... A flyer asking for female models to take part in a glamour/adult photoshoot for an upcoming photographer's presentation. Kate didn't even pause for thought as she pawed inside her bag for her mobile phone and booked an interview with the photographer. That evening we took a few full length nude shots and emailed them off to him for his approval.. It was several days before we heard back from him, and to be honest we'd begun to think that we never would. Sure enough though, he was delighted with the pics we'd sent, and felt Kate was the perfect woman for his project. We agreed a time and place, along with a suggestion of cloths etc for Kate to model. The day of the shoot, my wife woke up extra early and spent a great deal of time and effort making sure her hair and make-up were just perfect. I must admit, when she finally came out of the bedroom ready to go, I was blown back by just how gorgeous she looked! It wasn't long before we'd reached the location of the shoot, and entered the studio for our first look at the modelling world. It certainly looked an expensive setup, with lights, multiple cameras and sitting in the middle of it all a very posh looking sofa.. Once we'd had the meet and great with the photographer, Kate disappeared into a side room to make the first of her costume changes.. The first 100 or so shots were pretty standard stuff..various clothes, various states of undress, various poses. It wasn't until we started the final set of shots that things really took off.. Kate came out dressed in her new lacey black bra and panties, along with some black matching stockings and the highest pair of "fuck me" heels I'd ever seen.. Instantly I knew this would be a set of photos I would want myself! We started off with the usual stuff - Kate in various poses, and finally her removing her bra throughout a series of shots..Then he asked her to remove her panties - something he'd not done in the previous sets. Kate didn't hasitate.. We'd known something like this might happen, as the advert had mentioned adult shots.. I was now rock hard as I sat quietly in the corner, watching my wifes legs spread wide for the camera to see her trimmed pussy. The camera continued to click away as he got her to tease herself with her fingers.. Without warning, in steps a young man and greats the photographer..Kate and I are shocked to learn that the youngman is infact a 19year old model called Christian who would be helping with the final few shots..While Christian pops off to change, Kate looks over at me in horror; not sure how i'll respond, or how she should respond herself..We talk it through, and its decided that we should push on, and stop only if it gets out of hand.. within minutes Christian walks back into the studio completely naked and sits down beside my wife..Its obvious why he's a model, the athlectic toned body, strong jaw, surfer style hair, and ample assets in the cock department.. which quickly grew to what I'd guess to be the thick end of eight inches as he eye'd up my sexy stocking clad wife. My cock was now straining hard against my jeans as each shot grow more and more intamate, with the two of them asked to hold each other in certain styles for each pose. Then the big shot came, Kate was asked to drop to her knees and take Christians cock in her hand...Kate looked at me, wondering what to do. I was still sitting several feet away in the corner as the action was unfolding.. I gave no reply to her look, so she did as requested.. Over the next few shots, she did as directed, and took his throbbing cock to her mouth and licked the tip and pumped his shaft several times. Next she was motioned back on to the sofa with her legs spread wide and her knees bent.. Even from my spot in the corner, I could see the moist drips from her pussy - this young guy was clearly getting to her... Then Christian was asked to move between he legs and position his cock at the entrance of her pussy. Once again Kate shot me a glance, expecting me to stop the whole thing. Instead she found me with my trousers down, furiously masterbating. The look in her eyes changed as she looked back at Christian, almost giving the young stud permission to use her..He knew exactly what she wanted, and began easing all 8 inches into her.. Kate let out a soft moan of pleasure as he filled her dripping hole, all the time the camera clicking away in the background. Christian began grinding away slowly, as his hand ran down my wife's face along the side of her neck, resting finally at her nice firm brests. Kates hands were grabbing away at the sofa wildly as she attempted to adjust her position and allow her new young stud to penatrate her deeper. Christians tempo changed, unable to hold back any longer..He grabbed the sofa firmly with both hands to anchor himself, and began pounding into Kate like a jackhammer! Kate responded by wrapping her beutiful stocking covered legs tightly around his back to hold his cock inside her as much as possible. I watched as the two bodies locked tightly together raised clear of the sofa, only to coming crashing back down with each powerful thrust.. Kates nails dug into his shoulders as she moaned and screemed between each piston like thrust.. OH FUCK......YES.....FUCK ME....YOU LITTLE BASTERD! Neither of them could take any more, and with a mixture of grunts and screams both Kate and Christian climaxed together..This was enough to send me over the edge as well, and I shot my load high into the air.. As Christian pulled his slowly softening cock from my wife, a huge amount of cum began leaking out and running down her leg..As the haze of what had just happened cleared, the relization that kate may have just been imregnated came apparent.... Thankyou for reading..
