It Happened I Don't Know Is I Should Have Allowed It

So this weekend that's passed my cousin was leaving to another city and if you read my other confessions its about my wife and my thick cocked cousin. Before he could leave to another city I called him over for a BBQ. While we were outside I would call my wife to sit on me and I would kiss her grab her ass and try and do forward things with her to make him horny.. After the BBQ my wife went into the bathroom now this is when things got hot cause I seen his thick fat cock before so while she was showering I told him, that while having sex with my wife I mansioned to her the size of your cock! and she wants to see it. She finished in the bathroom and she was wearing a skin tight leather pants a white top that has a v in the middle which exposed her red bra on the inside. Thru the pants you could see the lacey red hot shots she had inside it was sexy. But she was in for a shocker as she got to the entrance of the room my cousin and I were in, she froze cause there in that room was my cousin and I pants down to the floor I demanded her to come in and hold both of them touch them feel the difference thickness and lengths to feel the difference in sizes she was tennis no lie she was scared but boy when she got started she was wanking the both of us like she knew exactly what to do. Then she started sucking his fat cock I've never experienced something like this so I really didn't know what to expect. But watching her suck his cock up and down side to side licking the pole of his thick cock licking his larger head then mine watching her open her small little mouth as wide as she could to see how much she can get in.. This happened about 10 minutes or so I could see he was started to get close he busted a nut all over our titled floor about 7 shots of sperm as my wife lust fully looked over she went straight into the bathroom I was to scared to go on so I got him in the car and now his gone far far away from us.
