My best mate Gary, who I have known since school, went thru a messy divorce.It was mainly his fault not being able to keep his prick leashed.We are both 35 and Gary started dating a cute 23 year old, Ruth. Ruth is 5 foot 6 tall, a brunette and a nice pair of tits to go with her shapely body. Gary took her away for a dirty weekend to Amsterdam a couple of weekends ago. On his return he asked if I would do him a favour. I told him I would. He told me since he had taken Ruth to see a live sex show she had been desperate for someone to watch as she was fucked by him. They could only watch, no touching or getting involved. We agreed I would be that someone last Saturday night. I told my wife I was going out for a drink with Gary and would be home late. I met Gary down the pub at 8pm and had a couple of beers. Gary was on soft drinks as he said he wanted to be able to get keep an erection as Ruth was a bit of a nympho in bed. We left the pub at about 9.30pm and went to his house. Ruth met us at the door. She had a french maid outfit on. Her boobs were wobbling about and were near to falling out of her tight little outfit. Her legs looked great in black stockings. She escorted us into the lounge. She had laid it out like a small theatre. The settee and armchairs had been pushed to the side, the armchairs behind the settee, with a large blow up double bed mattress on the floor in front of them. Ther was music being played in the background. She offered me a drink. I sat on the settee and I had a good view of her wobbling boobs as she bent over to give me my drink, a large vodka and tonic. She then dimmed the lights as she and Gary left the room. After a couple of minutes they both came back into the room. Gary was wearing black shorts and a black singlet. They both got on the mattress in front of me. They started to dance and Gary eased Ruth's top down exposing her lovely boobs. I guess they were a good 36 inches. Ruth then pulled Gary's top off, then in time to the music he removed her top and unzipped her little skirt. She stepped out of it and kicked it away. She then stood in front of Gary and as she eased his shorts down she got on her knees and took his prick into her mouth. She sucked and licked his shaft and he became erect, his prick was about 7 inches long and was quite thick. Gary then pulled her up and slid her g-string off. She turned towards me as she kicked the g-string at me. I caught it and looked at her as she stood facing me, just in stocking and suspenders. She had a shaved smooth pussy with a lovely looking split. She parted her legs and Gary stood behind her. He put both arms around her and played with her boobs. He then moved his right hand down to her pussy and found her clit, which he began to rub. She was moaning with delight. Gary then manouvered her and she laid her down on her back and spread her legs, giving me a good view of her pussy which looked beautiful and moist. I now had my prick out slowly wanking it. Gary got on top of her in a 69 position and sucked away on her pussy. After 5 minutes she came with a loud shout. Gary the laid on his back, Ruth got up and straddled him and eased herself down on his prick, giving me a good view of her being fucked. She went up and down on him, squealing with delight. After 5 minutes she got off him and got on all fours. Gary then entered her from behind and fucked her. As he went in and out of her pussy, her tits went back and forth in time to her being fucked. After a couple of minutes he withdrew, Ruth got on her back and he got between her legs and wanked his prick. He then came in a burst and his spunk shot up, hit Ruth in the face, tits and belly. I stopped wanking, otherwise if I came my wife would wonder why I would not want my usual saturday night fuck and blow job. I am lucky as my wife Julie, likes to swallow my come. Ruth asked if I enjoyed the show. I told her she and Gary were great performers and her talent was wasted. She then asked if others would be interested in watching her being fucked. I told her I would make some discreet enquires down the pub and let them know. Hopefully next week she will perform with Gary, as I have got about 4 interested blokes who want to see her naked and get fucked. I will keep you posted.
