Lusting After Boss

My boss is a stunning 50-year-old woman. She is a former TV news reporter, who is lively and a lot of fun to be around. She also has a beautiful ass and what look to be 36C tits. I work closely with her, and there is definitely sexual chemistry between us. I’m close to ten years older, stay in good shape and dress well. I am also married. I get a hard on every time I am with my boss and she has to notice. Because she’s my boss and we are both married, I’m hesitant to make a move. But that, like my cock, is getting harder and harder every day. Really want her, and if she said the word, I would do anything she wanted . What should I do?
