He is my work colleague, we have always been sexually attracted to each other! But he is married. I asked him to come over for tea until I convinced him, and we ended up in bed. He called his wife and lied, saying he had an important meeting and would be home late! After he hung up, he was unsure because he had never been unfaithful before. He told me we would do it, but he wouldn't look at me so he wouldn't feel guilty.
