I learned to suck cock in my younger years and had sucked many before getting married. I had forgotten the pleasures of sucking a man's hard cock when it happened again.
My wife had a guy over who she would fuck from time to time, and I would normally watch them and then get my sloppy seconds once he would leave. I was always nervous about what my wife's reaction would be if she saw me with another man. Then one evening, they were playing around and he told me to come over to see how wet my wife's pussy was. When I was looking at her pussy he moved in front of me and told me to suck his cock for him while he ate my wife out. I did not know what to do, but he grabbed the back of my head and I took his cock into my mouth.
He looked up from eating my wife and I will never forget his words, "Damn, you give an amazing blowjob, this is definitely not your first time sucking a dick." A few minutes later I felt him begin to cum and I continued and swallowed every drop he had. As his semi-limp cock slipped from my lips a feeling of fear raced through my body, but to my relief, my wife was looking and smiling at me.
"Fuck that was hot baby!" was her words to me.
