I always had quite a high sex drive and me and Rob had great sex until about 2 years ago when, how shall I put it, his ability to perform, started to wane. To put it bluntly more and more frequently he just couldn't get it up. We used to have sex nearly every night, if he wasn't away working, but over 18 months it got more and more infrequent until about 8 months ago it was down to once or twice a month. He refused to go to the doctor, to embarrassed I think. He's 11 years older than me at fifty four and shrugged off the problem. I tried to reassure him it wasn't a problem, though it was, and that I was happy masturbating, using my vibrators, or him using his fingers or tongue to give me the occasional orgasm. However, I liked to have sex most nights. No, like is the wrong word, craved , yearned, desired, needed to be fucked. I suppose that it was inevitable that when the opportunity presented itself, I didn't resist the temptation. It was early spring, a warm day and a chance to wear a suit with a skirt instead of trousers. I always wear stockings and suspenders with a skirt or dress, I find them more comfortable and hygienic than tights. With pretty matching panties and bra I felt quite sexy, looking at myself in the mirror in my underwear, wondering why my husband couldn't get it up, despite my decent figure, flat stomach, nice little bum, good legs and my tits, which after boob job are a firm 34dd. I looked at my face, OK a few lines around my eyes and mouth but with my make up on, I reckon I scrub up pretty well and am told I look younger than 43. Rob called out he was off, not even a kiss goodbye, even though he was going to be away for two nights. A quick cup of coffee then the 30 minute drive to the the office where I work as a PA. Peter, the executive I work for had arrived in January, a high flyer in his early thirties, divorced, good looking and tall, a bit of a workaholic. We got on well, and I was rather flattered that more than once I noticed him watching my reflection in the window, particularly my bum. More than once I masturbated at night, imagining him fucking me. I enjoyed the day, crossing my legs, letting the skirt ride up, flashing plenty of thigh when I sat in the chair opposite his desk taking notes. I wondered if he'd noticed the little tell tale bumps from the suspender clips and if he knew I was wearing stockings. I had to ask him to repeat one instruction after I started daydreaming, imagining him peeling my panties off and fucking me, which made my pussy wet. My panties felt so wet that afterwards I had to pop out to my car to fetch a clean pair I always keep in the glove box in the car. A quick visit to the loo to change, using the already soiled panties to wipe my wet pussy. On my return Peter called me into his office and as I passed my desk I dropped the used panties and keys in my desk drawer. At 5pm I finished my work, went to say goodnight, then walked to the nearby Tesco for a few things. I returned to my car in the staff car park, got to it and couldn't find my keys. I emptied my bag before remembering I’d come down to the car earlier and left the keys in my desk. The building was still open, and I took the lift up to the top floor, walked to my office and opened the door. My desk is off to one side, standing next to it, turned away from me was Peter. He jumped, turning towards me. I dropped my shopping, gasping “What are you doing?” though it was obvious. I'd thought momentarily that he was wiping his nose on a tissue, then recognised what he was holding to his face. My lace panties, over his nose sniffing, the gusset in his mouth sucking my pussy juices from them. His trousers and underwear were pushed down to the top of his thighs and in his hand, his impressive cock. A good 8 inches at least, fully erect as he wanked. I took all this in a seconds as he dropped my panties, tried to hide his prick and garbled an apology. I closed the door behind me twisting the lock and moved towards him staring at his lovely prick. He glanced up, looking worried. “Are you going to call security?” he asked. I had recovered more quickly than him. “Only if you put your cock way. You really are a bad boy” The worried look was replaced by a smile as he realised I was enjoying the situation. I thought I had the upper hand, how wrong that proved to be. He quickly recovered, reading my reaction perfectly, picked my panties up, pressing them back to his nose and inhaling my pussy odour. His hand moved back to his cock, stroking his erection, he sucked my panties then dropped them back on the desk. “I love the taste and smell of a woman’s cunt” he told me. “I love the taste and feel of a mans cock” I replied. By then I was standing next to him. I reached for his prick and wrapped my fingers around it, realising how thick it was when I couldn’t encircle it with my fingers. I started wanking him as he unbuttoned his shirt, pulling it off, his chest was almost hairless, I kissed his shoulder then his nipples. I pushed his trousers and underwear down and he moved to take them and his shoes and socks off. I unbuttoned my blouse, then reached behind me, unzipping my skirt. I let it fall to the floor, kicking it away as I removed my blouse, unclipped my bra and dropped them on the desk. Peters cock was standing up hard and proud, almost touching his belly button, he pushed me back over the desk. He started massaging my tits, teasing my nipples even more erect. I reached out searching for his cock, grabbing it, stroking his hardness. He sucked my nipples, I felt his hand on my tummy, fingers slipping inside my panties. I opened my legs, cursing myself for not shaving my pussy for a couple of days as I felt his fingers on my mound then touching my clitoris. I moaned as I felt his fingers touch my slit, rubbing along it, feeling my juices flowing, pussy opening as he pushed a couple of fingers in my hole. He moved his lips from my tits, his tongue on my tummy, his fingers moving from my pussy. His hands pulling the material on one side of my panties snapping the elastic, then the other side, ripping my panties off. His head dropped to my pussy his mouth, tongue and lips sending ripples of pleasure through my body. I couldn't stand it, “Stop! Stop! I want your cock in me. Fuck Me, Peter. Please fuck me now” I cried out desperate to feel his cock inside me. He stood. I spread my legs wider, could feel my juices running out. He held my hips, dragging my bum to the edge of the desk. I laid legs spread, cunt gaping open, ready to take him. He held his prick, ran it along my slit, rubbed it against my button. I lifted my hips trying to get his prick inside me, he moved, teasing me. “For gods sake put it in. Fuck me” I begged. He carried on teasing me, the tip of his cock rubbing my pussy. I sat up and tried to grab his cock. He caught my wrist, forcing me back, holding me down. “You're an evil bastard. Just fuck me. I want you to fuck me” I spat at him. He grinned down at me. “You sound desperate” he laughed. “I am. I'm fucking desperate. I haven't been fucked for weeks. Please fuck me” He slid an inch or two in. “Is this what you want?” “Yes don't stop. Fuck me” I practically begged. At last he eased his cock slowly inside me, my pussy stretching to take his girth, my cunt juices soaking his cock as he finally gave me his length. He released my wrists, and started to slowly fuck me. I reached down, frigging my clitoris, rubbing my hard little engorged bud, biting my lip, an orgasm already building as he steadily shafted me. He fucked me harder, ramming his cock in me faster. I was getting closer, wanted to feel him deep inside me. I wrapped my legs around his bum, preventing him pulling to far out, lifting my bum to meet his thrusts. He grabbed one of my tits, pinching the nipple. I started to cum, writhing on the desk as my cunt muscles contracted, rippling along his cock. He groaned, then slammed his prick in and out hard, grunting with each thrust, his cock spurting jets of spunk, splattering deep in my belly. He stood, his cock still buried in my cunt, as I lay sprawled on the desk, struggling to open the drawer to grab some tissues. Peter took a handful, commenting that he'd been looking for them when he discovered my used knickers. I felt his cock slide out, his spunk pouring from my hole pooling on the desk before I could stop it with the tissues. Even after I'd wiped my pussy when I stood more leaked out, running down my legs, soaking my stocking tops. I found my bra and put it on, picked up my ripped panties, dropped them in the bin, looking for the other pair he'd been sniffing. He held them up, then put them in his pocket “For later” We tidied ourselves up, he asked if my husband would be wondering where I was and I told him he was away for a couple of nights. I hoped he might invite me to dinner, but instead he just gave me a smack on the bum and said he'd see me in the morning. I drove home, sat on a plastic bag, his spunk leaking from my pussy soaking my dress, thinking what a “Bad Boy” he was and knowing I wanted more. The next morning I thought things might be a bit awkward. I was at my desk before him as usual, and he didn't arrive until mid morning, after attending a meeting. He came in, asked for his messages, checked his appointments were as planned and went through to his office as if nothing had happened. I took him coffee and stood waiting, until he looked up, and thanked me. I'd taken my time dressing that morning, a nice dress, not to short, which showed off my figure, hold up stockings, a lacy bra and silk panties covering my freshly shaved pussy. At 5pm I shut down my computer, returning some reports to the cabinet. I went to his office to say I was off. He looked up, “Before you go there's something I need you to do” “OK, what is it?” I asked still feeling peeved with him. “Take your dress off” he said. “Why?” I asked. “All day you've acted as if nothing happened last night” He shrugged, pointing out we were not paid to fuck in office time. “If you don't want to that’s up to you” I wanted it, my annoyance with him evaporating as I pulled my dress over my head. Reaching behind my back undoing my bra, removing it. I stood in front of the desk his eyes moving down my body, taking in my tits, nipples sticking out hard. He told me to go and lock the outer office door, watching me as I walked to and from the door, cupping my tits, tweaking the nipples as I slowly walked towards him. I was intently aware that my pussy was getting wet, wondering if a damp patch was visible. He pushed his chair back from behind his desk, he'd got his cock out, stroking his long, hard erection. I walked around the desk, standing in front of him, bum resting on the desk, parting my legs, I touched myself through my damp panties, desperate to feel his cock inside me again. “Is your cunt getting wet?“ I nodded in reply. He told me to continue rubbing my pussy though my panties. I did as he asked, my pussy opening, the material pushed in my hole absorbing my juices, my fingers feeling the wetness. He watched then told me to pull my panties to one side so he could see how wet my cunt was. “Take them off and give them to me” I pushed them down my legs and stepped out of them. Bending to pick them up, I could see his cock, wanted it inside me more than anything. I stood and handed my wet panties to him. He knew what I wanted but said “Play with yourself. Wank first then I might fuck you” He was deliberately tormenting me, making me masturbate when he knew full well I wanted his cock. I spread my legs wide, reaching down to touch my clit, running my fingers along my gash, wanting to please him, let him see my gaping pink hole, wet and ready for him to fuck, hoping he'd be unable to resist. He'd lifted my panties to his face drawing in the smell of my sex juices, licking my cunt secretions from the sodden gusset, stroking his prick, watching me masturbate. He inhaled again, sniffing my panties before wrapping the silk around his cock as he wanked “I love your cunt scent” he told me. He lent closer watching my fingers flashing in and out of my pussy as I masturbated. I was breathing heavily, close to cumming, eyes shut thinking of him as I started to climax. I shrieked I was cumming, forcing my fingers hard in and out of my pussy, when I heard him sigh. I felt something splash my face, my eyes shot open in time to see a second load of spunk hit my tits, then another jet land on my tummy and hand near my pussy. I hadn't been expecting it “What are you doing. You've wasted it. I wanted you to cum inside me” I cried, sitting up frustrated and disappointed, feeling his spunk running down my face and body. He wiped his prick on my panties before replying. “If you want me to fuck you. You'll have to get me hard again Won't you” “And how long will that take?” I asked. He pulled me off the desk, pushing me down on to my knees, his cock in my face telling me “Suck it and see” I took his cock in my mouth, I could taste his spunk, a hint of my pussy juices on the shaft were he'd held his prick wrapped in my panties. I used every trick I know to get him erect, sucking his balls, holding them and squeezing gently, wanking his cock while I sucked, taking his cock in my throat until his prick started to grow in my mouth. He began to stiffen, I stopped sucking for a moment, wetting a finger with saliva, popping his cock back in while I reached between his legs. I touched his bum, my wet finger finding his anus, circling it teasingly, pressing more firmly feeling the resistance give as I slid my finger in his arse. His prick twitched in my mouth, fully erect, my lips tight around his shaft. He had got hard again in only about 15 minutes, ready to fuck me, something Rob my husband couldn't have done even in his prime. Peter tried to start fucking my mouth, but I wasn't going to let this go to waste. I stood and took hold of his prick, then straddled him, guiding his lovely fat 8 inch cock to my pussy. I rode him, bouncing up and down on his prick, cumming twice before he lifted me off, bent me over his desk and took me from behind, fucking me hard until he eventually came inside me. Now, most days after we've finished work I suck him off or more usually he fucks me before sending me home to Rob with a pussy full of spunk. I even went on a business trip with him to meet clients in Hamburg, when he took me to a club, which was a real eye opener. More recently Rob was away and I went with Peter to a do at his Rugby Club. What happened at his flat afterwards, with him and several of his friends is another story!!!!
