Something happened a few weeks ago, which will probably change my wife’s life forever! Pam is a very attractive woman, petite, size 10 and a blonde. She’s always been a bit of a flirt and dresses quite sexily, much to many men’s delight! But that’s where it has always stopped….just a bit of harmless flirting. A mate of mine, John, has always had the hots for her. There have been times at parties where he has danced with her and his hands have wandered a little, but she never objected and just put it down to a bit of drunken fun. Like her, I could see no harm in him showing his feelings for her. John’s wife left him for another man a few months ago and since then his sex life has been non-existent and for that matter nor has his social life. In order to cheer him up Pam suggested that we invite him out with us to drown his sorrows. He was delighted and took up our offer straight away! On the Friday night in question, she was clearly feeling a little mischievous and she dressed in the most revealing clothes imaginable, explaining that it was to cheer John up. She wore her long boots, just above her knees and the shortest of mini skirts, topped off by a very tight clingy vest, which showed off her bra-less cleavage wonderfully. The thick, deep red lipstick put the finishing touches to her very tarty image! She may have looked a bit tarty, but I went along with it because she looked so horny. I had to agree with her that John would love it! We met up with him in town and had a few beers and all really let our hair down. It was an incredible night and judging by John’s roaming hands, he appreciated Pam’s outfit. Come 11.30, rather than say goodbye to John, Pam suggested he came back to ours to have a few more beers and crash out. One taxi ride later, we were all back home with a beer each, chatting and listening to a bit of music in our lounge. I’m not sure how the conversation got onto the subject, but we found ourselves discussing John’s sex life, or lack of it! And then, Pam, being rather drunk by now, asked him when he had last had it! "Last week actually!" he surprised us! "Who with?", Pam asked. His answer was a shock! "I paid a prostitute £75!" he answered, looking really embarrassed! "I would have done it for £50!" Pam laughed. John reached for his wallet and took out £50 and handed it to her, calling her bluff. I joined in for a laugh and told her she was all talk! That was like a red rag to a bull. She took the notes off him and climbed onto the floor, the money still grasped in her hand! "Come on then John. I’m your whore for the night!" she said in a slightly slurred voice, but all of a sudden looking quite serious. Despite her teasing him, I assumed that she was about to admit that she was winding him up, so I encouraged him, wondering at what stage she would stop! "Go on John. Fuck the bitch. You’ve paid for it!" I joked. With that, he got down on the floor next to her and simply pulled her tight little vest up over her shoulders, leaving her naked from her mini skirt up! It all happened so quickly I had no time to react. The next thing his hands were all over her tits as I just sat there open mouthed and watched in total disbelief! He squeezed them gently at first, rolling the nipples between his fingers, then his head went down and he began sucking them, alternating from tit to tit! She was sitting up, leaning back on her arms and still holding his money! He reached down to her tan leather mini skirt and lifted it right up to her waist, revealing her little lace thong. Wasting no time one of his hands moved down to between her thighs and began stroking the lace covering her pussy! She started to moan. Her eyes were closed and her head rolled backwards. I was mesmerised and totally speechless! Why I didn’t stop them I don’t know. He pulled the thin gusset of her thong to one side and I could clearly see my wife’s swollen lips. His fingers slipped deep into her wet pussy and began working away at it. She screamed out loud, blatantly enjoying it! Pouting her lips at me as her hand reached for his zip and expertly pulled out his hard cock! She started to wank it, slowly at first, but then more frantically as he increased the pace at which he was fingering her! "Just fuck me you bastard. You’ve paid for it. Just fuck me!" she cried out. He pushed her back onto the floor and pulled down her thong and then he opened her legs wide and climbed between them, his cock eager for action! With one sudden, hard thrust he was inside her, his arse pounding desperately up and down, driving his cock hard and deep into my wife’s cunt! Her arms were wrapped around his back and I could see that she was still clenching the £50 she was earning! As he fucked her through her first orgasm, he grunted away "You dirty fucking whore! Slut! You’re nothing but a prostitute!" "I know. I know!" she screamed! Within a couple of minutes she was climaxing again. This time louder and so intense, different to anything I had experienced with her! He fucked her and fucked her until eventually his pace quickened and his breathing turned to frantic panting. "I’m fucking cumming you whore!" he groaned as he made his last deep thrust into my wife. His face flinched as he emptied his balls into her unprotected hole! I watched him slowly pull out and as he did, a trickle of cum dripped from her cunt onto the carpet! I wondered whether she would give him the money back, but she didn’t. She simply reached for her handbag and pushed the notes in, like a real whore! John looked over at me nervously expecting an angry reaction, but it wasn’t disgust the feeling I had, it was more like excitement. I realised that I had enjoyed watching her acting like a whore! She’d obviously liked it too and it had been easy money for her. John apologised, but I just grinned and he appeared to relax again. I couldn’t wait to get Pam to bed and we had the most incredible sex ever. I could still feel his cum oozing out of her onto the bed as we fucked. John has fucked her a few times since and has always paid her for her services! She has also brought a couple of guys back from our local in the afternoons when I am at work. One thing I have insisted on though is that she uses condoms when she is working and that she describes to me in detail everything they have done with her! Her life is totally different now and, if anything, it has brought us closer together! She has extra spending money, but that is nothing compared to the excitement it has brought into our own sex life!
