I usually have most of my encounters with my partner Sarah, but this was a spur of the moment encounter and one of those that just happen I had met Kay when she asked me to call to her house to discuss some work she needed done in her home, she is in her forties, married with four kids. She is just an ordinary mother and wife that works and also takes care of her home, and like most married couples life becomes routine and a little bit dull. Kay is very good looking and has a lovely toned and slim body, the first thing I noticed was how good her arse looked in her tight jeans, she has small pert tits and massive big nipples that always seem to be erect. We seem to have a chemistry going between us and over the course of a few meetings to finalise her project we got on really well. Kay took time off work to be in the house when I was doing the work, the first day she was buzzing around delighted to be getting her improvements done, I found it hard to concentrate as she bent over to give me lovely views of her arse. The weather was sweltering and that didn't help, the cool breeze through the open window had her nipples poking through her t-shirt. As the day went on the flirting and double meanings got more raunchy and I was really getting turned on. The next day went much the same, but this time something happened, we just met in a door way and as I tried to squeeze by our eyes met, suddenly I found myself leaning in to kiss her, and she responded by putting her hands on my head and kissing me back. It was intense and frantic, my hand went under her t-shirt to feel her tits, her nipples were just amazing, long and hard. Nothing was said as we made our way to a bedroom just down the hall, I undid her jeans and slipped my hand inside her panties, her pussy was natural and very very wet. I slipped a finger inside and she let out a soft moan, then we both just got naked quickly, both sweating from the heat of the sun as well as the passion building between us. It was all happening so quickly, our hearts pounded as I backed her on to the bed, kissing deeply as we did and still nothing being said. She lay back on the bed and opened her legs for me, an open invitation to claim my prize. Even though her pussy was very hairy and natural, her wetness had the hair matted and her lips were visible, glistening and open ready to be fucked. I climbed on to the bed and moved over her, she lay there silent as I moved into position and rubbed the head of my throbbing cock along her slit. I gently eased into, a little at a time, our eyes were locked together as I kept pushing into her amazing pussy until finally I was completely inside her. I kissed and sucked her nipples, they are amazing and she moaned as I did so. The heat inside her pussy was having an amazing effect on my cock, I started kissing her again and screwed her slowly as I did. She started to push her pussy against my thrusts and pulled me towards her, trying to get me to increase my pace. Suddenly she started to moan and said softly " Oh God, I'm coming", that sent me over the edge and I started to fuck her has hard as I could, my balls slapping her with every stroke. The only thought in my head was pleasing myself, I fucked her hard and fast and very soon I felt my balls tighten as I neared coming. I looked her in the eye as I started to come deep in her pussy, It was only the second cock ever to fuck her and I was filling her with my seed. We said nothing as we just looked at each other, my cock twitching as I pulled out of her well fucked pussy. Suddenly the realisation of what we did hit us, the chance some could have walked in!. We dressed quickly and talked about it over a cup of tea, she was naturally feeling guilty but didn't regret it as her husband is not interested in sex as much as he should. Next morning when I arrived she met me at the door dressed in a gown, hair wet from the shower, I pulled it open and kissed her again and we went to the bedroom to repeat it all over again. This time I went down to eat her pussy, the first time anyone had tasted it and it was perfect. I got her to suck my cock and we tried various positions before I came inside her again, this time doggy style as I admired her beautiful arse. I finished the work that day but we have made plans to meet up to continue our adventure, and I hope to get to take her anal virginity and fuck that amazing arse, I'll let you all know when it happens.
