A few years back I had an office affair with my secretary. She was 10 years older than me, but my goodness our affair was fun. It was without doubt some of the most passionate, loving and completely satisfying sex I have ever enjoyed. It lasted about 3 years.
We had a computer system in the office and she would use this to 'chat' to me in private. It was really difficult keeping a straight face when she described what she would like to do to me, or what she had done to herself whilst alone in the office. Occasionaly, a colleague would rush over and try to see what I was typing - I guess my face was a bit of a giveaway and I think a couple of them knew that there was something going on between us. She would delight in describing on the 'chat' how she had used her new vibrator whilst sitting in my chair when I was out of the office and she had the place to herself.
We would describe to each other how we would masturbate each other as soon as the office cleared. She knew just how to turn me on both in words and in practice. By the time the office was empty, I was rock hard and she was dripping wet. She always shaved her pussy and wore stockings and it was a real thrill to sit opposite and play with my cock while she got to work with her vibrator.
She would often masturbate me and she knew exactly how hard to hold my cock for my maximum pleasure. She would pull my foreskin back so slowly then gradually build up speed. Sometimes if she sucked my cock first, my foreskin would be especially slippy - it was dreamy. She could control my urge to cum so easily, yet could keep me going for ages. Crucially, when I finally came she would stretch my skin tight back whilst my spunk flew. So many girls carry on wanking hard whilst you come - I find that really uncomfortable and it sort of hurts!
I liked to return the favour too. She had quite a prominent clit which I could easily stretch out from under it's hood by pulling the top of her shaven pussy with my thumb. Oral sex was a particular favourate of hers, but I liked to wet my pointer finger with her juices and circle her clit by stretching her hood so it peeked out from underneath. In this way I could enjoy the show! She would quiver her legs with excitement on approaching a 'Big O' then quietly moan in contentment as her pussy throbbed post climax.
Our record 'Big O's' as we called them was 10 each in an afternoon session of about 3 hours. I was absolutely spent after that and was having very modest ejaculations, but god, was it good!
I still have wank fantasies over our fun times.
