About 3 years ago, me and the wife had a family friend over. He was black. We were drinking and I went to get more beer; they stayed at the house. I came back and looked through the window and saw my wife bottomless with her legs spread getting fingered by our black friend. I watched as he fingered her snd caressed her thigh; she was squirming in pleasure. I got immediately rock hard watching! I pulled my cock out and started stroking until he made her orgasm. I never said a word about it to her.
