Looking for a story

[harrgo461945]

I remember reading a story about a wife who disliked a particular male co-worker. He had a reputation with the ladies but was too confident for her liking. Anyway, one days she decided to give in to his advances for whatever reason. They end up in a car and he performs oral on her. I think her husband has arrived unexpectedly and he watches. They then drive to a remote spot and she returns the favour. He however wants full sex so they end up doing that.
I have tried lots of searches - co-worker, player, car, husband watches etc but although I find many interetsing stories I can't locate this one.
Can anyone help please?
