Making wife a whore

My name is Brian I’m 57 so is my wife Val. This story happened when we were 46. Val is small about 4ft 10 tall fat but has great tits 38dd and a nice ass short hair and hairy pussy. Our sex life was very poor and not exciting but I was going to change that. I planned in my head to let other men use her, the idea turned me on, she had one weakness and it was if you bet her or dared her something she go out off her way to win. On the night in question I was joking I bet she wouldn’t let my mate grope her, she didn’t like him much and I knew she thought he was a dirty old man, Sam was 66 always talked dirty and was wild groper. She agreed bet he was allowed to touch her and she couldn’t abject for an hour. He arrived and we had drinks. Val dressed in tee shirt I noticed she had no bra on and a pair off tight leggings. Every time she got us a drink he grope her ass she cringed at this but done nothing. The sex talk got dirty as the drink flowed and he said I suck her tits dry if I could. I joked well you can if I want to, she looked at me with daggers in her eyes but decided to teach me a lesson, she stood up and removed her top, her tits looked awesome, she walked over to Sam and leaned over putting them in his face. Sam took advantage of this sucking them hard. I noticed Sam’s hand was between her legs rubbing her pussy through her leggings. I heard her groaning got louder, she lost control, I watched Sam drag her leggings and pants roughly down to her knees and finger her soaking pussy to she cum all over them he called a dirty little slut and pushed to the ground. I shouted fuck the slut, we dragged her leggings off her and I watched Sam shove 8 inches of cock deep inside her, he was giving her no mercy as he fucked her hard and heard him scream I’m cumming. Then he filled her soaking hairy twat, he climbed off her, it was my turn I was so hard and fucked her like a whore to I explored as well I told Sam he could fuck her anytime he wanted to. Val said I’m not a whore, yes you are I reported as we lay in bed. Later she told me she enjoyed it but I said I wanted to make her a proper whore, she looked shocked and disappeared into bathroom and returned completely shaved. I fucked her hard and then I fucked her in her ass, it was first time she was in pain but I was happy, the next 4 days and nights sex was fabulous, Sam was fucking her during the day and me at night then one day Sam give me a lot of money. I said what’s that for, he said he was prostituting Val to guys he knew and got paid. I was shocked but happy, when I saw her I told her I loved her and I wanted to invite world to fuck her. I even made her have sex with woman but that’s another story.
