My wife is 38, with runners legs and bum, pert c cup breasts and a reasonably taught body despite giving birth. She's generally quite conservative, and more attractive for the fact that she is generally unaware that men would like to shag her when she walk's past in a dress and heels. Generally conservative, she can, on occasions become a willing slut, and this is one such time - its such a turn on. My wife had an interview and really wanted the job, and I suggested that she should improve her chances by adopting her sexy secretary look, which is really hot. She doubted my judgement, but on the day, decided to try it. The interview was late afternoon, and I agreed to drop her off and pick her up, doing some early Christmas shopping in between. She was wearing a crisp white blouse, and white push up bra, tight pencil skirt with a slit to ease movement, and stockings and suspenders, the clips of which showed through the fabric of the skirt. High patent heels completed the outfit, but to add to the look she had her normally bobbed hair up and wore glasses that complimented the look. As she swayed into the offices, I noticed blokes stopping to follow her taught firm arse and legs. About 90 minutes and a text later I collected her and she came out full of herself. Apparently the interview had been by the Divisional director, and he had made no secret of the fact that he liked her outfit. She had spent most of the time trying to subtly let the skirt show more leg (not easy and the one disadvantage of the pencil cut) and part way through had undone a button of the blouse to reveal far more cleavage than was decent. We stopped for food and a drink on the way home, and felt and caressed each other throughout. I was turned on because of how she looked and kept pointing out to my wife the various men that were watching her. Before we left the restaurant, she went to the loo and came back and handed me her knickers, which were damp. AS we drove home I took a meandering route, and pulled into a secluded layby that I had sussed out previously in the hope of one day using it with my wife. We started kissing, and I was teasing her erect nipples through the fabric of the blouse, when I suggested we get out of the car for some fresh air. She was quite nervous about someone else pulling into the layby, but agreed that the chances were small and the risk was itself a turn on. I slowly removed her blouse and bra and took her nipples in my mouth sucking and nibbling as she likes, her hips were moving involuntarily, and she desperately wanted to be fucked. I undid the zip on her skirt and it made that magic rustling noise as it fell to the floor. She stood, naked apart from heels, stockings and suspenders and I wanted to take her immediately, however, I sank to me knees, and began licking her. As I did she closed her eyes and began groaning louder and louder, approaching orgasm. Just then, she obviously heard a car slow down and froze, as headlights turned into the layby. I grasped my wifes hips and kept licking as we heard a car door open and shut, and then steps approaching. My wife, was unsure but desperately close to an orgasm, and unwilling to abandon it. She started groaning again, as a young British Gas fitter in uniform, approached and started stroking his crotch. My wife saw him grow in front of her and being watched and licked into a frenzy she went over the edge and came with a scream and a shudder. Next thing she was on her knees and pulling my cock out, and licking the head, as the guy walked closer. Soon she was taking me all the way into her mouth, and the guy was literally only inches away, he looked enquiringly at me and I nodded, and he reached forward and stroked her breast, lightly teasing her nipple. My wife groaned and I felt the sensation on the tip of my cock. She carried on sucking me, and he rightly judged that he could touch some more. He started to explore her body, and the then ran his hands down he perfect arse, and under teasing her pussy and she groaned again. Suddenly, she changed position, while still sucking me, but giving him easier access to her pussy. Without any warning, he took his 7 inch knob and entered her, and she squealed, then carried on sucking. She was now obviously incredibly horny and I was about to blow my load watching my wife be a wanton slut. The guy started ramming her rapidly, with her trying meet his thrusts with her own, and me feeling the impacts transmitted to my cock through her mouth. I then exploded in her mouth and she drank it all. I started teasing her breasts as she took this gas fitters pipe, and I could tell she was soon to cum again! I leaned over and sucked her nipples, flicking my tongue from one to the other and felt her shudder as she orgasmed. Then I saw the guy stiffen and cum into my wife. He then zipped up and left to call his girlfriend. I wouldn't let my wife get dressed, and as we drove home, I switched on the interior light every time we went past a tall vehicle. Many lorries tooter their horn at her that night. When we got home, I parked a little way away from our house, and my wife had to sprint to the door in just her stockings feet and suspenders - but sadly no neighbours were around. We spent the rest of that night fucking, and she was awesome. Hope you enjoyed the story, please give me constructive feedback, as I'd like to improve.
