When i was 19 an older work colleague of 38 used to do dirty things to me in her car. She would often stay late at work just to give me a lift home.
It was bloody lovely right up until the point that i went to a new girlfriends house to meet her parents and it turned out to be her mum.
All i kept on thinking was, as i shook her dad's hand, was that i've shagged your wife and daughter.
I carried on seeing both for a while but it started getting weird when the mum would buy the daughter sexy underwear as 'that's what he would like to see you in'.
Still...she was very good.
