This experience was towards the end of a business trip to see a client in the south with a work colleague who I had been having an affair with for some time.
The day had an air of expectation as we had talked about having some fun on our return but before going to our respective homes.
Jane had previously said that she would take her bra and knickers off in the car but I took this with a pinch of salt.
As we got out of the city and hit the motorway I jokingly reminded her of this and she proceeded to do exactly as she had promised. This wasn't an easy task but as she was wearing a blouse and skirt she managed to take her bra off without removing her blouse and slipped her knickers off as I drove.
I asked her to show me her tits and so she undid her blouse so that I could look across and see them. I reached over and put my hand inside and felt the weight of them and her erect nipples. Then I asked her to show me her pussy and to my pleasant surprise she pulled her skirt up so that I could see her dark bush. This got me very turned on, not least because she was obviously in a dirty, playful mood.
I then reached over and she opened her legs so I could touch her pussy. Keeping my eyes on the road I slid my fingers down between her legs, gently easing them between her pussy lips. I soon felt her wetness and she was clearly very turned on. I told her so and started to gently massage her clit.
I love playing with her as she does get deliciously wet and has a very tight pussy.
I continued to masturbate her, slipping a finger inside now and again. After a minute or two I asked her if she was going to cum, and she replied that she was nearly there. This surprised me as I hadn't been playing with her for very long and so she clearly was enjoying the excitement of the situation; the experience of being played with as we drove along a public highway.
Sure enough, after a little more stimulation she gasped and I felt her pussy contract and her body spasm as she had an orgasm. It was a strong one and I continued to rub her as she came down from it.
This had made my cock very hard and I needed some release but unfortunately there was no opportunity to stop for some time and Jane refused to wank me as I drove, in retrospect quite sensibly but at the time I wanted her to. Eventually we came across a service area and pulled in, finding a quiet spot.
It was now dark and so we climbed in to the back seat. Expecting to be able to have sex I had some condoms with us but this had now been ruled out as we were running late, and so desperate to cum I eased my trousers down a little and got my cock out and rolled one on.
Jane began to wank me and it felt incredible as my cock was very sensitive from being turned on for what must have been a couple of hours by now.
I groaned as she pulled my foreskin tight and I could tell that it was going to be a good cum.
Within only a few minutes I could feel the orgasm approaching and I let myself go and my cock began to pump cum in to the condom. I wasn't disappointed and it was a very powerful orgasm and Jane carried on slowly pulling on me until I had finished.
We then went in for a coffee and a clean up before heading home. There was no further sex that day but it is an experience that I shall always remember.
There have been plenty of other experiences with Jane that I may share as several were masturbation themed.
