My wife is a very attractive lady. One night, a client of hers, a handsome black man, came to the house with documents for her to sign. We had a few glasses of wine and during the conversation; it transpired that he and my wife flirt. I suggested that they take it a little further and to my pleasure, they started kissing. He exposed her panties. This was a real turn on as I adore women's underwear. He stroked her pussy gently over her panties for a while, until he began to perform oral. My wife then undid his belt and fly and took out his huge black cock and began sucking him. She was now frantic with lust; she asked me if he could fuck to her, which I agreed to. I watched as he spread her legs and buried his thick black shaft deep inside her pussy and began fucking her. This was a fantastic time to see my wife so excited. It has been a tremendous boost to our sex lives. Perhaps one day we will do it again.
