Wife fantasy comes true

Wife has had a fantasy since high school, one or one year anniversary I made it happen

My wife and I went out for six years ( high school & junior college) then married that summer. We always had a good sex life. One time in or third year of high school she told me a good friend of ours sexy as hell. The guy was black guy black as coal, running back on the football team. He was always hitting on her telling her if she had him she forget me. At our wedding he told her, he now knows she was off limits. She teases him saying never know, she haves a fantasy of fucking him. Him and I play softball together during the summer. The week before our anniversary I asked him if he wanted to fuck Becky. I told him it would be my anniversary present to her. That night I set it up for him to show up at 9:00pm. We went out for a nice dinner then home, after a couple beers we headed to bedroom. Once naked I tied her hands and legs to the big bed post, then blindfolded her. Then teased the hell out of her eating her out real good, sucked her tits as I fingered her. Telling her I had a special treat for her. Dave showed up right on time, got to bedroom as planned, stripped got on bed as I back out. She was begging me to fuck her, as he lined up his coal black cock to her pussy. Dave slowly pushed his cock into her, she raised her hips as he pushed into her. Two strokes he was balls deep in her, holding it deep in her as she moaned “god baby you super hard tonight”. Dave started to fuck her slowly at first then picked up the pace. After a few minutes she yelled “oh baby I’m going to cum, fuck me harder baby”. I reach up telling her “this is your present baby” as I removed the blindfold. She looked at him then me, as her fucked her faster and faster. I untied her hands first she reach up holding his big hands as soon as I released her legs she wrapped them around him locking her legs. They fucking like crazy for about five minutes until she told him to get on his back. She got on top telling him to lay back and enjoy. She would raised up until he was almost out of her then drop down on him and that went on a long time. She was working up a huge orgasm and then she dropped down holding it as she was shaking yelling “give me that sperm”. Once she came back to herself he got her on all fours telling her he was going to shoot a huge load inside her. He had a death grip on her hips as he pounded her like a dog in heat. She would look me in the eyes as he was giving her the fucking of her life, two times her eyes rolled into back of her head. He was fucking her hard, deep and fast. I knew it was not long before he filled my wife with millions of his black sperm. She was on the pill so I did not care, but still the pill not hundred percent. Finally he moaned “here cums my babies,” that lite a fire in her, she yelled out “ yes bred me I want your baby” as she had another orgasm. I could see his ball sack tighten then release then tighten and release, I knew he was filling her with his black sperm. After he was done he stayed inside her, telling her he wanted to do it again very soon. She told him her pussy was his anytime he wanted. She wanted me to fuck her, I got between her legs slide my cock into her. She was so wet I felt his warm cum as I fucked her. I did not l last very long add my sperm to her already filled pussy. Dave ended up staying the night fucking her in our bed as I sleep in spare bedroom next door. They were at it hot and heavy waking me up at three in the morning. I was little wild me next door as my sweet young wife was getting blackened. I can’t explain it but it was a huge turn on for me. All I could do was think about what if he does knock her up.
