This is another episode with Karen. I am Paul And this story is completely factual. Our sex life was fantastic. Loads of threesomes and moresomes. Bi guy action and some light spanking. We always discussed our fantasies and if possible acted them out. One such fantasy was for Karen to be deprived of sight and restrained and have someone come in and fuck her , leave and she would not have seen him at all. This was to be arranged without her knowledge. I decided to throw in something else. She liked being used and treated as a slut and called one. I found a likely candidate on the Swinging site and arranged a meeting with me. I was looking for a Bi guy and someone that I could get on with. Had the meeting and the guy , another Dave, was just right. Personable , Bi and a nice cock. The meet was arranged. Karen was over and I had told her before that she would be blindfolded and restrained and I told her that I would fuck every hole. She is as horny as fuck!!! Karen is sexily dressed as usual. She knows how to turn me on with what she wears. Today , is stockings , suspenders under her coat and nothing else. She told me she wanted to get out of the car without the coat , but chickened out in case my neighbours saw her. She should have done it. We make the usual small talk. Funnily enough we don’t talk about sex, just general stuff. A glass of wine or two is consumed. I tell Karen that she must do everything I say if she wants to be fucked. She readily agrees, compliant girl that she is. First I tell her to suck my cock. She goes down on me and really goes to work. She is a great cock sucker and attempts to deep throat me. Can’t quite do it but feels wonderful. I am enjoying this but am mindful of the time because I want her tied and blindfolded before Dave arrives. I can’t resist (weak willed bastard) and tell her to sit on my cock. My cock slides into her cunt so easily. She is wet and tight. She gets a short , sharp fuck with my cock deep in her. I finger fuck her arse and she orgasms . That will do for the moment. Karen moves to the sofa bed and I tell her to play with herself whilst I take some photos. She brings herself off in quick time. I swear she must be the most orgasmic woman I have ever fucked. Time to restrain her. The restraints are black leather and are basically two loops joined by a small chain. The smaller loop goes on the wrist and the larger one round the top of the thigh. She now has her restraints on and she has her arms down by her thighs. She has little movement of her arms and can’t even play with her cunt. Two blindfolds are involved. One a black silky one to cover her eyes and the other a black leather one which goes on top. She can’t see. Perfect. There is a knock at the door. Karen says ‘Fuck, just what we don’t want’. I tell her from now on she can’t say anything unless I tell her to speak. Karen senses that something is going on but complies and says nothing. I let Dave in and show him to the living room where Karen is laying on her back. She looks like the perfect slut. I ask him what he thinks and he answers that she looks perfect and deserves fucking. She is mega excited but can’t speak. I wish I had gagged her but reflect that then we would not be able to use her mouth and that would be no good. Dave strips off ; he’s got a decent body and as I said before a nice cock. Dave starts to play with my cock getting it nice and hard before going down and taking it in his mouth. All this time as he is sucking me I am talking to Karen telling her what is going on. He’s good and sucks me all the way whilst fingering my arse. I have to tell him to stop before I come. I return the favour and suck his cock. It’s about six inches long but pretty thick and I manage to get it all in , which is something I am not very good at. Karen is very excited and is desperately trying to get a hand to her cunt, with no success. I say to Dave that he can fuck her whenever he wants and as arranged he says that she can wait. We both have a glass of wine and of course I have a smoke. I tell Karen to open her legs so that we can see her cunt. Fucking hell she is wet. I move over to her and go down on her. She tastes wonderful as I part her cunt and delve deep. And then switch to her arsehole. She loves it. Dave comes over and sticks his cock in her mouth. I decide to leave her cunt and join her in sucking him. Heaven for him and us. I tell Dave he should fuck her. Anyway he wants except her arse as I will be fucking that later. Dave wastes no time and enters her with no foreplay all the way in. I tell him to fuck her hard as she loves it. She is on her back with her legs wide open as he pounds into her. I position myself so that Karen can suck my balls and lick my arsehole. Fuck me I love that. Having my arse licked and fingered turns me on immensely. I tell her what a slut and a whore she is. Dave has slowed down now to an easy rhythm so that he does not come. That’s good as it means he can suck my cock. Again I describe to Karen what he is doing. She is shaking. We turn her over and as she can’t use her arms she is face down on her knees with her arse in the air. I give her couple of smacks , harder than usual and she moans with pleasure. Dave resumes fucking her from behind. He’s not going to last much longer and I tell him to come on her face. He pulls out and removes the condom. I turn her over so that Dave can wank over her. He does and comes a huge amount (honestly the most I have ever seen). Some goes in her mouth , over the mask , in her hair. She is plastered. Dave pushes his cock in her mouth so that she can lick it clean, which of course she does. I undo the restraints so that she can have a drink and relax , if that is possible , but do not take off the blindfold. Dave cleans himself up , has a drink and I ask him what he thinks. He says she was a great fuck and a real slut. Dave leaves and I take off the blindfold. The only sound she has made in the last hour or so is from sex. I ask her what she thinks of what happened. Perfect!!! She found the whole experience one of the horniest things she had ever done. The fact that she had not seen him was the most erotic thing. Being restrained and in essence used was great but the blindfold set it off perfectly. I found the whole thing very , very horny. Watching her being fucked, sucking cock and having mine sucked; her being used. I was extra hard just talking about it , so Karen went down on me and produced one of he best blow jobs. Why so good? Well she managed to make me come without using her hands to wank me. Only three or four women have managed that. I came in her mouth and she swallowed it all not releasing my cock until the last drops had gone. That feeling is fantastic. It almost makes me scream with pleasure , almost like pain it is so intense. I did fuck her arse later. Not hard. One of those long, slow and deep arse fucks. I come buried in her arse and just stay in there until my cock goes soft. We had both had what we wanted. Her fantasy about being used , blindfolded and restrained and treated like a slut and a whore had been done. What the fuck would we do next?
