So the wife and I have been married for over ten years and for the most part it’s been great. She’s very hot and takes care of herself. I have had a fantasy of watching her with another guy, preferably a black guy. My buddy at work is always talking about how hot she is and how he would love to have her. I’ve shared pictures of her with him and he is crazy about the idea of having her. I’ve mentioned him to her while we fuck and in the past she just brushes me off and that’s it. The other night I mentioned it again to her and she snapped at me and said look you’re lucky I give it to you so just shut up about it, I thought you stuck up bitch you think you’re all that. Fast forward a couple of weeks she had knee surgery and the doctor prescribed pain meds and knowing that she is very sensitive to them he told her not to plan any activity because they would knock her out. He wasn’t kidding the first time she took them she was out for eight straight hours. Then it hit me what a great opportunity to make my fantasy happen. That night she took her meds and 30 minutes later she was out, I tried to wake her up and no response. I called my buddy and told him it was a go to come over. A little later he was at the door I let him in and we went to the bedroom. She was laying on her back wearing just a pair of shorts on. I told him to enjoy and he smiled and said you sure she’s not gonna wake up? I shook her and she just laid there. He said oh shit she’s out. He pulled the blanket back and looked at her he said wow she’s so beautiful. He started rubbing her tits and kissed her. He then slowly pulled her shorts off and started rubbing her pussy. He got up and took his clothes off, his black cock was hard and ready. I got a bottle of baby oil off the nightstand and said here buddy by the size of your cock you’re gonna need this. He laughed and said yeah. He rubbed some on her pussy and his cock. He slowly spread her legs open and got between her legs took his cock in his hand and slowly began to push inside her. When he was about halfway in her she let out a little sigh but didn’t move. He slid all the way in her and looked at me and said shit man this is awesome. I said enjoy man. He then started to fuck her slow and steady after a while he started going faster and faster he looked at me and said I’m gonna cum where do you want it? I said fill her full. He let out a groan tensed up and buried his cock deep inside her, I saw his cock pulsation and pumping cum inside her tight pussy. He laid inside her for a few minutes then pulled his big black cock out. He got up put on his clothes and said that was fantastic thanks man you’re the greatest and left. I sat on the bed and watched his cum running out of her. I got a wet wipe cleaned her up and put her shorts back on covered her up and went to sleep. The next morning she woke me up horny and fucked my brains out. She had no idea what had happened. I love it when a plan comes together lol.
