Watching my wife suck another man's dick, let alone a black one. But it did happen after 25 years of marriage. M y wife's best friend was sharing her experiences with a black man and over time my wife was very curious and asked if she could meet the man at her place but not for sex just to see if she was comfortable around him. We had agreed that after 25 years of just each other maybe it was time to expand our sex life. So I said ok.
After work I asked her how it went. She admitted things got out of hand. After a 1/2 hour or so of good conversation her friend excused herself from the room and my wife said within 5 minutes his cock was in her mouth. She admitted she didn't resist much and let him finish in her mouth but wouldn't let him fuck her. She was amazed at his size (she only had my 5" for years) and his strength. I was upset that I had missed it and that he took advantage of her like that.
She then called him and invited him over on Friday to have a good time together with me there hoping this would calm me.. He agreed and so it happened. To say he took advantage would be an understatement. He came in and after exchanging pleasantries stripped her naked and had her kneel and fish his huge cock from his pants. She sucked him so eagerly and like a slut I was appalled and actually very excited too. It was a blow job like I never experienced. He cock slapped her called her names, fucked her mouth like a pussy, gagging her at times. She sucked his balls like I imagined a whore would. It wasn't long until he held her head and shot a load in her mouth and on her face and tits too. While still kneeling and holding his cock she looked at me smiling and said honey I told you I liked him! She sure loved that big cock many times after that. Meanwhile I was standing there embarrassed with a big wet spot on my trousers. He fucked her three times that night and she blew him again in the morning.
And that was our introduction into the lifestyle over 10 years ago. She has had many black cocks since and I have enjoyed watching her please them. I missed her first black blow job but have witnessed hundreds since then, so it's all good!
