We have just got in and Michelles pussy has been finger fucked by a taxi driver! We went out to a family do and had a long taxi drive home. We had fell out and Michelle sat in the front and I sat behind the driver. As the journey was going to be some time I fell asleep but woke up after some time to hear a little moaning and as my eyes adjusted to the light I could see the taxi drivers hand reaching well over and my wifes legs wide open with them resting on the dashboard in front of her. I still pretended to be asleep but got an immediate huge hard on as Michelle was obviously near to coming as this guys hand was rubbing her clit furiously and her hands were wanking his cock as he drove. Michelle began to moan that she was coming and his hand rubbed harder at her clit as she rubbed his cock in his pants. She moved a hand to her cunt and pushed several fingers up her pussy as she convulsed with an orgasm hard. She came and her pussy will have shot jets of cum onto the seat as I heard the taxi driver grunt with satisfaction as he obviously shot onto his pants whilst she was wanking him as he was driving, saying she was a dirty slut and that the other drivers were right about her and that she should let him fuck her next time and not just let him finger her pussy whilst she wanked his cock! My cock was so fucking hard in my pants and when we got home and got in bed I pushed her on her back and fucked her hard and fast and then went down on her pussy until she came. Now I am not sure what I am supposed to do, do I confront her with what I saw, especially since the taxi driver had some previous information about my wife, or do I wait until the next night out and pretend to fall asleep and see what happens? She goes into town frequently and when we have fucked before when she gets home I have found her cunt to be very wet, which she has always said before is because he has been dancing with guys who have got her horny and wet. I found this extremely exciting and is it possible that my wife whom I thought very straight laced might be a bit of a dirty bitch? What should I do? What would you do to my wife?
