I am a husband and father of two wonderful kids. Looks wise I'm more Johnny Depp than Johnny Vegas, I keep myself fit with regular gym trips and swimming. I never once cheated on my wife...until this past Christmas. It all started when we started hiring au-pairs, the first few were quiet efficient girls of 20-21 years of age. But our latest aupair, her name is Anna, comes from Poland. She is a real looker but thankfully, she is very conservative and religious and dresses modestly in jeans and plain jumpers etc. This Chirstmas my wife decided to take the kids away to her parents and as I was busy with work I would fly up to them for a couple of days while they spent the next two weeks with her folks. The night my wife and kids left something unusual happened, Anna said she was going on a date, she had never gone out before, nor had she ever mentioned a boyfriend, but I guessed it was her first chance to go out as my wife had taken the kids. I told her to go enjoy herself and settled down to watch the tv. Anna was upstairs getting ready for her 'night out' some time later the door opened and in walk Anna to say goodbye before she left for her date. What stood before me was an utter transformation, she looked incredible, her hair was up and her make-up and perfume only added to her desirability, I couldn't help but look her up and down appreciating every lucious curve of that taut body. Her bare tanned shoulders, her breasts barly contained in a red corset top. Down my eyes travelled, her soft-leather pencil skirt was black, almost blue-black, through it I could clearly see she had on a suspender-belt, the straps straining to hold up those seamed stockings, by the time I noticed how shiny and high her heels were I realised I had been staring silently at her for way too long. I looked sheepishly at her face, she was beaming, 'You like how I look?' she asked in that sexy accent, I tried to act cool and replied, 'yes, you look very cute.' She left, and I returned to watch tv, eventually I headed to my lonely bed and began to fall asleep. About 1am I heard the front door open and heard Anna return home, alone. She immediatly climbed up the stairs and I heard her heels clicking down the landing, they stopped outside my door and I could see her shadow hesitate outside before a gentle knocking on my door....'John, are you awake....may I come in?' 'Of course Anna, I am still awake...come in'. She entered the room, she seemed to be a little tipsy, although I could not smell any alcohol from her and her eyes seemed clear and sober. She giggled a little and began to tell me what a good guy I was, she sat on the bed, close to where I was, from where she was sitting I was treated to a great view of her breasts and she drew her stokinged legs up onto the bed which caused her skirt to rise high up her thighs. We chatted and giggled and she kept touching my bare chest tenderly, I was glad she was sitting so close to me, because behind her back I noticed a large bulge forming in the sheet I had covering me, I wished I had pulled a duvet over myself or indeed that I had left on my tight Calvin Kleins instead of sleeping naked but it was all too late now. As we spoke I tried to take my mind off my arousal in the hopes it would subside. The more I fought it the greater it seemed to swell, it felt like I had overdosed on Viagra. Much to my embarassment Anna turned around to see what was distracting me and stared at the large pole tenting underneath the sheet. She whispered something in Polish, then she turned to me and gave me the sexiest stare. 'I just knew you would be my kind of man, now I know what I can give you for Christmas,' her hand slowly pulled down the sheet and revealled my now rigid cock in all its swollen glory. I must admit I haven't seen it so engorged in many years, I have always been what my wife calls, 'built like a porn star' so Anna was more than impressed by my over-sized endowment. For what seemed like an eternity we just sat looking at each other, eventually I tried to speak, Anna put her finger to my lips and said 'hush' her left had slid down my chest then past my abs the she gently grasped my erection. 'We really shouldn't do this I said without any real conviction, 'maybe so' she replied while her index finger traced along the length of a bulging vein on my shaft. She began to slowly ease back my foreskin, I was so excited it slid back quickly over my glans. 'I have always dreamed about this night' Anna purred, and to be honest so had I. This is no good, this is not working, Anna said, I pretended to agree, yes, you are right we should stop here...but I had misunderstood her, she had no intention of stopping, she merely felt too restricted by her tight skirt, which she now hitched up over her thighs, I now was treated to the sight of those beautiful long legs, encased in stockings and black suspenders, the flesh at the tops of her thighs looked so soft, I could also she she had chosen not to wear knickers and that she had shaved herself, not so demure after all I thought. Things began to accelerate, before I knew it she moved her luscious red lipsticked lips onto my glans, she opened her mouth and took my head inside, she was obviously no stranger to this and her tongue expertly teased and touched me. She then went down as far as she could, but I had never expected she would be able to take all of me, but half-way down my length felt wonderful. Her moans vibrated down my shaft and I could feel myself begining to reach a pre-ejaculatory state. I grabbed her head, and pulled her to my lips to kiss her for the first time, our tongues probed each others mouths, she tasted of mint but not a hint of alcohol, I knew she was faking being drunk, but one thing was sure she would not need to fake anthing else this evening. Anna, spread her legs either side of my torso and lowered her hot firm body down onto my aching dick, slowly she travelled down the shaft, as if testing to see if it would fit, she left out a long deep moan and to my amazment she began to orgasm, no need to worry about coming too soon, she had already had her first and I was now begining to feel in total control. She bagan to move faster and faster on top of me, determined to make me come, but I thought why end this too soon, I flip her onto her back and began to thrust deep into her, she was very tight but really so wet it was as if she had used a lubricant. Before long she orgasmed again, I felt that maybe it was about time I did too when I noticed the bedside clock reading 5 am, however I had no idea if she had taken any precautions and as I didn't want any accidents I pulled out of her. She stared into my eyes with a wanton, almost drunken gaze, I went down on her and once again I had barely started with my tongue before she bagan another screaming orgasm. Enough was enough, I lay back on the bed and she instintivly understood that it was time to finish the job, this time she hurredly went down on me with her mouth tightening and loosening, her blond hair was flying as she quickened her feversish pace. She used on of her hands to pump my shaft with the other she squeezed and released first my left testicle then my right, over and over again. I began to feel the hot cum rise from deep inside my balls, maybe I should warn her that I haven't had an ejaculation in two weeks...maybe not... Anna's moans turned to a muffled scream as the excitment of blowing my giant dick overcame her and she began to have multiple orgasms, I tried to hold back but it was now good I left out a loud gutteral gasp and began to flood semen into her beautiful mouth. I could see her swallow each large spurt but it was too much volume at once and she needed to open her mouth and I watched her let some dribble down her chin and drip onto her cleavage. She swallowed what was in her mouth and hungrily licked up the spillage from my cock and balls and stomach. We both flopped down on my marital bed and held each other as our breathing returned to normal and we gathered our thoughts..... Soon Anna was deep asleep on my chest, my mind was racing, what had I done? I had never been unfaithful before, this au pair was in my home and under my care and I end up fucking her brains out, what is wrong with me. Dawn was breaking and Anna sighed and hugged me close to her soft skin, my guilt was running around in my mind, but my mornings have always been the time I am at my most horney, I hoped that last night would have taken the usual urge away from me but oh-oh, I could feel myself slowly but surely swelling down my thigh, I hoped I could keep the growing down to a semi but the more I attempted to distract my thoughts the faster my dick seemed to grown. I prayed Anna would not awake to the sight of my erection as it began to really stretch and swell down against my leg, no good a sudden memory of how great last night was cause my dick to spring viciously into the upright postition, it slapped against my stomach, and in doing so hit Anna's cheek which was resting against my chest. She awoke, and let out a long lazy groan, her hand went directly to my member and started to milk me, slowly at first but then as she became more awake faster and faster, squeezing and releasing as her hand attempted to grasp around my swollen shaft. I wondered what she wanted to do but she seemed satisfied to continue like this and never moved her face from the line of fire, occasionally she turned her head into me and gently bit my skin, my breathing quickened my abs tensed and I moaned, 'my darling' then I came hard into her fresh, young face, she moaned with pleasure. Wow, thank you for that I gasped, your welcome my lover, now I must go shower and freshen up, you can join me if you would like...I didn't need to be asked twice.
