Me 40[M] and my wife went out for dinner in a weekend away from home. During dinner we started to sexually provoke each other until the point we rush to pay and wanted to get back to the hotel. On our way back we took a cab and we started kissing and touching each other a lot. At one point she laid with her face on my lap and I started to touch her all over her body. She was wearing a nice black dress and I started to caress her legs more and more until I reach her panties. Once in a while I was checking if the driver was watching but he was always looking forward (good driver ?) Then I start to rub her pussy over her panties and asked her if she wanted me to stop, on what she answered with a clear “please don´t”. I was so turn on as she was. At this point her panties were completely wet and I slightly slided aside and started to finger her with one finger. She was loving it and trying to control herself not to moan. For the first time during the trip, I notice the driver looking at us by the mirror and she notice that too but we didn´t stop. On the opposite we went a little bit further. I then pull her paints slightly down and her dress slightly up showing her perfect landing strip pussy (at this time the driver was more looking to the mirror checking us then to the road) I then, start to finger her harder, with one, then 2 and then 3 fingers until she cums hard. After that we arrived at the hotel minutes after and continue an excellent night of sex which started in a completely new way for us.
