Wifey dreams about sex with someone else

My wife (F27) and me (M30) have been married for few years now. One day few months back, when both of us were drunk and horny, we were discussing fantasies. She told about her fantasies like getting gang bang. I could not hold myself and confessed to her how I get hard imagining her with other guys. Over time she started teasing me during sex saying things like ‘do you want see you wife being a whore’. That makes me so hard and almost makes me cum immediately. Yesterday she told she told me she dreamt about being fucked by strangers while I was watching. It turned me on much. She said she doesn’t understand why she is having these dreams. She had these dreams two days in a row. Although we only do this online and do not want to do it in life. But this turns me on so much.
