Wife taught me
Wife and I have done mmf for a while, and I love to watch her give head. She also likes me to eat her out after another man c*** in her.
After a couple of times she told me that she got turned on thinking about watching me orally service a guy while she watched. I told her that I was willing to give it a go for her. Afterwards I told her I like a man in my mouth more than watching her do him.
After I told her that, and she bought me a pair of panties and told me that it would turn her if I wore them for our next mmf. That turned out to be extra hot!
Then she got me a garter belt and stockings for our next mmf. I wore them under a suit and tie for dinner and drinks with our bi friend, then when we took the guy back home for our mmf, after I took off the suit, she pulled out a pair of high heels and told me to put them on and go down on him while she fingered herself and watched.
After a couple more times she told me that what she really wanted was for me to fully dress, including a wig, and have a guy give me a***. She said she would give me oral at the same time, so I told her I was game to try. Wow! Hot, hot, hot!
