Last saturday evening we had the disappointement of not getting a couple in who we had asked round and had to cancel because of illness. I asked Mrs N if she would be happy if I invited the young fella we’d had round a few weeks previously. He’s a nice young man and seemed very willing to play out scenarios. Mrs N was to be my sex slave. Well the guy arrived. We've met him before. She was instructed to pour us a drink first. I did it in a way that was domineering and made told her to be quick about it. She duly did her duty and went off to the kitchen to get our drink. When she returned I told her that our guest had paid a lot of money for our services and that she must do everything she could to make him comfortable. I instructed her to sit down next to him and start feeling his thigh and see what he was packing in his trousers. Must admit she was very eager to do it. Too eager really. He is a nice young guy though and to be fair I could see she was very attracted to him. It was going to be no chore fucking this guy, that's for sure. Let me describe how we got round to the subject of doing this. We'd been trying to get a couple round but as usual it had gone pear shaped. We'd met this guy before and knew he quite liked role play. My first suggestion to Mrs N was to be our dominatrix. "Oh noooooo" she said. "I can't be bothered with that. I hate it. I'm too lazy to think of all the things a dom is supposed to do" "Soooooooo..... Right so you are happy to be our sub. How about you become my sex slave for the evening ?" She Shuffled uncomfortably in the chair. " but without too much hesitation she said "Yes". I'll be honest she is very very happy to be a sub. And I think she She loves being controlled and told what to do. I went back upstairs and Texted our guy and let him know about the scenario. His reaction naturally was one of great excitement. This was going to be a special night. Next I thought I'd better make sure we had a safe word in place so we agreed on that. I did forewarn her that I might be different. After all she is going to be my slave and would have to do our bidding. I might be a bit harsh but she was to remember it was just role playing and if I did anything uncomfortable she could say the safe word at any time. So that was how the scene unfolded which I am about to tell you about. So to return to the story. Mrs N had put a remote control love egg in her pants. I gave her new master the contol. " What's this he asked". Use it and you will find out. Mrs N jumped a little and a smile went across her face. That's a good start I thought. I told her to kiss her new master. He's a really good looking guy and she really really didn't hesitate. I love watching her when she is feeling horny with a guy. Lovely deep french kissing. tongues and all. making my cock hard now just thinking about it. so everyone was relaxing and the butterflies were subsiding. I asked the new master what he would like my slave to do. I reminded him he had paid good money for her servicing (not really by the way incase you are wondering) " I want her to kneel between my legs and service my cock and balls". " Help him out of his clothes immediately slave and make sure you fold them neatly". He sat back on our sofa and she knelt between his legs and started to give him a wonderful blow job. He's got a lovely big dick and I could tell she was loving it. As I said earlier this was no slave chore, she was his and would do absolutely anything he wanted anyway. I forgot to mention earlier that I had our whip in my hand just incase she was not satisfying her master enough. One of his fetishes is to have his nipples squeezed and pinched. If she didn't do it enough I gave her a few licks of the whip. I must admit I did do it quite hard and drew a few sharp breaths and an "ouch". I don't find it easy being a master tbh. I don't like to inflict pain but she seemed to be enjoying it so carried on a bit more. I must admit a tinge of envy she was enjoying his big cock so much. I thought I'd better take them upstairs. I had plans for her to be fucked this time in our bed. I asked. "Would you like to go upstairs and share our bed with the slave". "Do you mind if I have a drink of water" He asked. "Yes of course", I replied. I nearly forgot and was about to do it myself. " It was lovely to instruct her to fetch us a drink. " And be quick about it". We got up to the bedroom where I had set up a naughty chair. I told the slave to sit in it and I would blindfold her. Her task would be to service the 2 cocks in front of her. I told her she was to select the one she preferred for fucking. I stripped off my clothes and stood in front of our slave. Must admit I had gone down slightly and was semi flaccid so I knew she would want the young master more. It didn't take me long to rise to the occasion but he is a little bigger so really there was no competition. She sucked him deeply, indicating the choice had been made. I took the blindfold off and said that the slave can now look at the goods on offer. I did get a few licks and sucks but she really wanted him. Mrs N is a bit full of bull shit about not being keen to meet men but I know different and I know what she likes secretly. She pretends that she isn't that keen on meeting other men but when cock is offered to her on a plate she doesn't need that much persuasion. It is that which I find quite exciting in our relationship. So moving on a little I realised that the new master had successfully seduced my slave into wanting full sex with him. He'd been a perfect gentleman and had brought his own rubbers which had been placed on the bedside table. I said " Right it's time I left you too alone now. The new master should be allowed to have time alone with my slave to enjoy her without me hovering and faffing around. I am going to leave you alone and if you want to have a fuck feel free. I will be in the room next door and might peep in now and again." I left the door slightly Ajar. I do have a bit of a fetish about listening to her having sex with other men and we have done this scenario a few times. I love listening to the soft groans and what they say to each other. He kept telling her he was a good slave. The first thing he did for her was to lay her back gently and then get between her legs and licked and sucked her. She ooooo'd and moaned a lot. Next they changed positions and he asked her to suck his cock and get him ready to mount her. I didn't watch this part but guessed she was helping him to rubber up. I couldn't really see what they were doing as he was on our bed with his back to me as she pleasured him and got him ready. I sort of drifted back and forth between the room next door and the crack in the door I'd left. I was fascinated. He was very tender and loving and they did a lot of snogging. It was great that she was loving this new young lover. I hoped she was really taking a shine to him so that we could do it again sometime. She gasped as he entered her for the first time. Then came the glorious sound of her soaking wet piss flaps being banged and banged and banged. She was sooooooo noisy. I hoped the neighbours didn't hear. Bang Bang bang. He went on and on. Now mrs N isn't a spring chicken so I was a bit worried she might be over fucked. But what the hell, we had a safe word and she wasn't saying it so I left them to it. next time I peeped in she was in that position I know so well when a man has a big cock. Legs over his shoulders. Slut shoes round his ears. Giving her a dirty big banging." Fuck I thought." She's enjoying that. Probably too much but what the hell. A woman needs a good fucking now and again. it keeps you young. She was slapping his arse too to make him pump harder. That's always a good sign. I knelt on the bed next to them. She reached out and wanked my cock. Pulled me a bit closer so that she could take my cock in her mouth as he pounded away. By now she was shouting OMG OMG. as you do. I pushed my cock in her mouth hoping to shut her up. It was just so passionate. The master suggested that he wanted to do her doggy. OK I thought lets add an extra dimension to that. I would get underneath and 69 with Mrs N while he fucked her. His cock and balls would be in my face and I would have to service them both with my tongue. What a position. As he fucked her I grabbed his arse and used him like a fucking machine. Powering him in and out of her cunt. I have had the same done to me while I have been fucking and it's wonderful to be totally out of control and to be used as a piston being driven in and out of a wet pussy. Occasionally he'd withdraw and making me lick her juices off her cock. Each time she gushed all over my face. At one point there was more than I could handle and I was swoooshed with copious quantity of fanny juice. I'm afraid my tale is nearly over. The last thing slave did for her young master was to let him lay back and then wanked him to completion. I'd went in behind her as she did it and fucked her beautifully fucked pussy. All lovely and slippery. I just love entering her after she has been fucked. I call it a teflon coated fuck. Feels lovely. I then went and knelt next to the young master and put our cocks together so that she could gobble and wank them at the same time. That felt so nice and I’ll be honest I exploded all over him. Her final instruction was to pinch his nipples really hard again as he wanked himself to an explosion of cum and join my seed covering his belly. A beautiful cum tribute for a beautiful slave. I have emailed the guy since and spoken about what was said while I was out of the room. At one point he whispered in her ear that he was going to fuck her. Did the slave want that. She whispered back yessssssss. He also told me that they snogged alot too. I think this is a scenario we should explore further. Hope you enjoyed my new story.
