When it comes to sex I've found it's impossible to second guess what or who turns people on so the best idea is to take a chance and now and then you'll get a pleasant surprise, which is what happened to me about five years ago. I was doing some electrical work for a very attractive young professional couple, I'll call them Mr and Mrs P. She was dark, almost Spanish looking like Penelope Cruz, very slim and fit with a firm bum and smallish tits which meant she often didn't bother with a bra and her cheeky nipples got a public outing. He was fair, tall and looked well muscled with his tailored suit trousers showing an impressive bulge that he liked to adjust while he was chatting on his mobile. I'm bi so I looked them both over whenever I got the chance but I'm also Mr Average in looks and build and sexually they were way out of my league. Also as people, they were a nightmare. Rude, arrogant, never happy with anything and they mostly behaved as if I was invisible. But I needed the money and even worked weekends so I could get it all done and move on. One Saturday I was there and they came back from the gym, both in fitness gear that left little to the imagination and glowing from a work out and shower. They' d had a row in the car and carried on indoors, ignoring the fact I was there. Apparently Mrs P was upset that Mr P had been paying too much attention to some young thing on the running machine. He soon had enough and sped off again in his new Merc with her shouting behind him, 'Fuck off back to your little whore then you stupid cunt, see if she'll take it up the arse twice a day !' Charming I thought and busied myself with some wiring. But Mrs P hung around the kitchen where I was working and for the first time ever got quite friendly and chatty with me and I twigged there was a bit of revenge flirting going on. Normally I'm sure she wouldn't have given me a second glance but maybe I was going to be the right man in the right place at the right time. She made me a coffee, then asked if I could check one of her electrical appliances which wasn't working properly and I said sure, lets have a look. A few minutes later Mrs P came back, she'd changed into a short black dress and carried a large black vibrator which she placed in front of me with a straight face. 'What's the problem with it?' I asked. 'It stops and starts. At all the wrong moments' 'Could you show me ?' I said, as innocently as I could manage. She sat at the kitchen table facing me, opened her legs, lifted her skirt to reveal no knickers and a neatly trimmed, jet black bush, turned on the toy and started working it into her pussy. She leaned her head back and closed her eyes as it gradually disappeared inside her and the smell of her cunt juice hit my nostrils. Then the vibrator stopped and she cooly said, 'See what I mean. Very unreliable. What would you suggest ?' I didn't need to be asked twice as I took off my jeans and pants in a world record time and moved towards here with a hard on like a stick of Blackpool rock. Then the vibe started once more. 'Done it again ! So frustrating', she said but now turned around with one leg on the chair, one on the ground, the vibe in her pussy and her amazing bare arse towards me. I went to press my cock against her bum but she put a stop to that. 'Sorry, no main course before you've eaten up all your starter'. I guessed what she meant and parted her cheeks with both hands and began teasing her sweet hole, circling around then sticking my tongue into it which twitched as I did so. I know some people don't like rimming but if it's clean and smooth then a woman's arsehole can be a wonderful thing, believe me. It wasn't long before the combination of my tongue and her vibrator gave Mrs P a lovely strong orgasm and I grabbed her while it ran through her body and she slowly withdrew the toy. I thought this was a good time to take control and she had no objections as I turned her around and sat her on the kitchen table, taking her dress off over her head as I did so, then spreading her thighs as she lay back and began to play with her own erect nipples. Again I took my cock to work it inside her but again she stopped me, putting one hand over her pussy until I knelt on the chair and moved my head towards it which she kindly allowed. I soon got over my disappointment by working my tongue over, around and against her surprisingly large clit while also lapping up a good taste of her cunt which was still very wet and easy to penetrate with my fingers. I held the top of her legs to stop her sliding back on the table and she pushed against me so we soon got a nice rhythm going and it wasn't long before she came again, more noisily this time, calling me a 'fucking dirty bastard' several times and even squirting a little against my face, which was an unexpected bonus. By now I had an erection that could have opened a coconut and wasn't going to take no for an answer. I slid her off the table, turned her around and told her to hold on to the table edge while I firmly took her hips and moved her to a position where I could slide into her from behind, which I did with absolutely no resistance from her wet cunt to my raging hard on. Despite its wetness her pussy was still tight enough to make for a really good grip on my cock and I resisted the urge to bang away but took my time while straining very hard not to come. I told her to move back and forward onto me while I stood still and admired the view and let her control the fucking for a while, then teased her by pulling out and rubbing by knob head around her arse and her clit before sliding all the way back into her. After about ten minutes of this it was obvious we both couldn't hold back any longer so I roughly grabbed the back of her long black hair and held onto it as I pushed deeper and harder than before. I came first with a great rush of spunk inside her and just as this was coming to an end she began to tense up and with one hand reached around and held my arse to stop me pulling out. She had a long, drawn out orgasm, saying nothing this time but making small noises of pleasure and relief. Once we'd got our breath back we quickly put our clothes back on in the knowledge that Mr P might return any minute. She went off to shower and change and I finished up my work so I could make an exit. The job only lasted another week and I worked when they were out so I never saw her again. But when they left me an envelope of cash on my last day I noticed that some of the notes had a familiar, musky smell to them, and a couple of black pubic hairs fell out when I removed the money.
