Yes. Years ago now though. She had an affair with someone at work who was fucking other women from there and from elsewhere too. His wife had left him. Wonder why.
I got the details from her bit by bit over the course of time. She went to his house a few times. Sucked him off in the bath; fucked in and on his bed and even fucked behind a Cathedral wall one evening! He was spunking in her regularly and I was fucking her too. And I was licking her cunt. I didn't know all this at the time. Gets me off while wanking even now!
