The Minster's wife

Our local minister (57) is a real conservative type and a hail and brimstone preacher. Says he is strong and fit and ready to fight the devil's horde. But he isn't up to fucking his wife, if he's fucking anyone it's not his wife 49. How do I know because I'm fucking her, and I don't go to church at all. I (51) run a small shop near the church, my wife died of cancer in 2019 and my children are grown and have started their own families. Being close to the church and having adjoining gardens makes it easy for me and the minister's wife to get together. My garden is directly behind the minister's house which is beside the church and with fruit trees in the back garden blocking the view of the fence. I installed a gate, and she comes down after lunch and we have sex in a shed in my yard looks like a potting shed, but only has a bed in it. My shop is closed on Sundays not because of religious reasons, very few customers and not worth opening is main reason. Also, I get to fuck the minister's wife neither of us are anything special.
