I'd made friends with Chas at the gym. We'd worked out and sauna'd together several times, and a few times we'd had drinks in the bar afterwards. Carole would wait in there to pick me up. I could tell that she found Chas interesting, especially after I told her - in bed, while we were screwing, to add something extra - about how fit and well hung he was. She asked me if we three couldn't get together sometime. As he was at that time unattached, I invited him around for dinner on the following Saturday evening. While Carole and I screwed that morning I asked her if she really fancied having a session with him. She shyly admitted that she found him attractive and wouldn't mind as long as I was there as well. I asked her if she fancied feeling his big prick right up inside her, as mine was at that moment; she said that she did, and then started to come. Later on, we tried to think of a novel way to introduce the idea. I suppose we could have just gone for it but that did not seem subtle enough, and what’s more, it might frighten Chas off. In any case, despite her enthusiasm Carole was quite reticent when it came to making sexual advances. Even after three years of marriage I usually had to start off our lovemaking, although once she got going she was totally uninhibited. I suggested that we talk about hypnotism. I had been interested enough to read some books on the subject a couple of years earlier so I knew a fair bit about the theory. I'd actually tried it on Carole but had only succeeded in putting her into a very light trance, after which we stopped as she'd been worried about taking it any further. We worked out that I would pretend to hypnotise her and she could practice her acting skills by being convincing as a subject. After all, she couldn't be blamed for anything she might do or say whilst hypnotised, so she could do whatever I suggested when she was supposed to be under, then we could see what happened. Dinner and wine came and went. Over the empty plates I worked the subject of hypnotism into the conversation. Chas was sceptical but I told him that we had tried it and I could get it to work on Carole. There was some more discussion during which we got Chas to ask for a demonstration. After a convincing amount of demurring Carole said she didn't mind so they moved to the settee with me on a dining chair facing her. I performed the usual relaxing talk and passes, and Carole soon seemed to be asleep as I had commanded. I told Carole that she would not hear anything until I said the words "Listen to me" - I'm a fan of "The Ipcress File". I then told Chas that I would try to make Carole do something uncharacteristically daring, and also try to make her very suggestible for the rest of the evening. I asked him if he minded me making her do something sexy and he was very enthusiastic in his reply. Because of her sensual nature, I said, she should not be averse to doing almost anything I suggested even though she wouldn't dream of doing so in front of a virtual stranger under normal circumstances, so why didn't we see how far we could go before she reached her limit? He liked this idea. I said to Carole "Listen to me" and told her to open her eyes, which she did. I first tried a few simple commands - "Raise your right hand," "Stand up", and so on. I got her to sit and then told her that she was a sensual woman with a lovely body (all true), that she liked her body, was proud of her body; she was especially proud of her lovely breasts and sexy vagina. She enjoyed showing her body to men. I asked her "What do you like to do?" And she replied in a masterly impersonation of someone who is hypnotised "I like to show men my lovely breasts and vagina." I carried on like this for a minute or two, telling her that she liked to feel and squeeze her breasts, and getting her to do so. She made a really good job of massaging her boobs, even undoing the buttons of her top and slipping one hand under her bra to play with her nipples. Then she slipped her straps down and got her tits out to be able to play with them properly. While she was doing this she started to breathe heavily and shut her eyes. I suggested that she could masturbate; one hand came off of her breast, pulled up her skirt, went down into her panties and started playing with her clitty. Chas was enjoying every moment of this display. After a couple of minutes, with her panties to one side and her cunt fully exposed as she seemed on the point of coming, I told her to stop playing, relax and listen. I then suggested that when I woke her she would feel hot and sticky and in need of a shower. I said she would have to take a shower and afterwards want to prepare her body with perfume and anything else she liked, and then dress in something sexier to show off her lovely body. I suggested a short skirt and her black see-through blouse and nothing else except shoes. I went on to tell her that for the rest of the evening she would want to do whatever Chas or I suggested, whenever we started a sentence with the words "It would be very nice if you...." Finally, I told her that she would forget everything when she went to sleep for the night. All through this she played her part to perfection. Chas seemed totally convinced that she was under, and suitably aroused by her activities. I told her to put herself away and do up the buttons. When that was done, I told her to close her eyes, and wake when I reached five. I slowly counted to five. At that point Carole opened her eyes, looked a little confused, and asked me if the hypnotism had worked. I told her the demonstration went fine, returned my chair to the dining room and poured some more drinks. As I was doing this, Carole said that cooking and serving dinner had made her hot and she would pop upstairs for a shower and a change of clothes. I sat on the settee next to Chas to watch TV and talk about what Carole had just done. He was very impressed by her body. Twenty minutes later she reappeared dressed just as I had said. The blouse was see-through but not totally transparent, so her 40DD's showed tantalisingly with her nipples standing out like two gooseberries stuck onto her breasts. She stood in front of us and asked if we liked her outfit. I could see Chas appreciating it. We both said yes, and I asked her what knickers she was wearing, at which she lifted the front of her skirt and said "none". There, in front of our eyes, was her perfectly bald pussy. She liked to keep herself trimmed, but earlier she'd given herself a close shave to ensure that she was completely smooth with not a trace of stubble. The view was lovely, with the front of her slit glistening moistly. I said to her "It would be very nice if you could pour us all another drink" whereupon she went and did just that. Chas and I grinned at each other knowingly - he was thinking how well the hypnotism had worked. As we sat with our drinks I gave Chas the nod. He said to Carole "It would be very nice if you would undo some buttons" and without comment she undid all the buttons of her blouse. Next came "It would be very nice if you would take your blouse off" which she did straight away. After allowing her to walk around getting nibbles, and as she was standing in front of us with her breasts proudly pointing at us, I said "It would be very nice if you would show us your bottom." Without a word Carole put down her drink, turned round and with her legs a little apart bent forward at the waist. She lifted her skirt over the small of her back, thus exposing her lovely round arse and, in between, the soft pouting lips of her cunt. "It would be very nice if you would let us stroke your bottom" said Chas, to which she replied "You can stroke it if you like." We both started running our hands over her bum-cheeks, and then I gently moved a finger in between her labia while Chas used a hand to caress her heavy tits, which were hanging down and gently swinging. I soon slipped my finger right inside, and then I placed my hand back on her arse and Chas slid his finger in. Then we stopped, said thank you, and Carole resumed her seat wearing just her skirt as if nothing had happened and she did this all the time. After a minute I said "It would be very nice if you would take off our clothes." Carole came over and, dealing with an item from each of us in turn, removed our shirts, then our socks, trousers and finally underpants. She then sat between us on the settee; we both had hard-ons. My erect prick is a fairly standard six and a half inches, but Chas had nine inches and the girth was in proportion - a whopper. I knew it was big, from the gym, but I'd not seen it erect before. I said "It would be very nice if you would hold our pricks and give us a wank" and she immediately took a penis in each hand although her thumb and middle finger did not meet by at least an inch round his monster. She started rubbing both of them, which was fine for me as I'd been getting it regularly, but Chas obviously had not because very soon he was moaning, and after another minute or so shot an enormous load of spunk. The first jet hit his chin, the next his chest, then his stomach, and the dregs trickled out over Carole's hand and down his shaft onto his balls. "It would be very nice if you would lick that semen up for Chas" I said, and off she went, licking it all clean and swallowing every drop. This really surprised me, as Carole was not often keen to swallow whenever we had oral sex. The dirty bitch, thought I. While she was carrying out her cleaning duties leaning forward over Chas' body with her bum in the air I stripped off her skirt and got stuck in from behind. It was very erotic, shafting my wife as she was licking spunk from another man's body, and it was not long before I planted my seed deep inside her. By then Chas was clean of spunk and she had taken his limp tool in her mouth and sucked it to attention. She could only just get the helmet into her mouth. As I withdrew she gave his prick a couple of strokes to attain full rigidity. She moved forward and straddled him, and just as she was gently lowering herself to take his mass of meat into her I saw some of my spunk drooling down from her cunt onto his glans, which would provide added lubrication. Just as well, as his tool was significantly bigger than what she was used to, both in length and girth. She lowered herself until two or three inches had forced its way into her. She then raised herself until only the tip was in place, and lowered herself again on his lubricated tool to take a little extra. She repeated this several times until the entire edifice was up inside her, although she must have been stretched in every direction far more than ever before. Then she ground slowly up and down, giving a little gasp each time the top of his knob pushed up into the extremities of her guts. She gradually increased her pace. Chas helped by moving his pelvis up and down to her rhythm. This time he gave a much better account of himself. Carole came three or four times before he shot his second load. As he came to climax, and his prick swelled that last bit in readiness, she was groaning with a mixture of pain and pleasure, and she cried out as his member pulsed with his orgasm. She continued to work him until the orgasm had run its course. While this was going on I had been tossing myself off and by now I was more than ready again, so she remained straddling Chas and twisted round to give me a blow-job. She had to lift her fanny clear of Chas to do this and I could see his almost flaccid but still impressive prick covered in love juices with more dripping down from her cunt. I put my fingers on her clitoris and gave her some more orgasms while she wanked me off into her mouth, and Chas stuck three fingers up inside her cunt to help. When I came in her mouth, she again swallowed all the spunk without wasting a drop. After a rest with liquid refreshment we indulged in some more sex-play with both of us managing another shag. Then Chas had to get going; we were exhausted and went straight to bed to fall instantly asleep. ---------------------- The next morning we awoke and as we lay there Carole said "What's this?" She pulled back the sheet and where she had been laying was a mess of dried semen and cunt-juice. "Where did that come from?" she asked. "Inside you, of course" I said. She looked a little confused and told me that she wished that I'd wake her up if I were going to screw her during the night. She got up to go to the toilet and complained that her fanny was tender and that I'd been too rough. When she came back I asked her if she could remember much about the previous evening. She thought for a while and said no, nothing after me trying to hypnotise her. She said that she must have dozed off, and that it was very unkind of me to leave her asleep all evening, without even waking her to say goodbye to Chas. So now what should I do? Tell her what happened, and probably cause all sorts of marital discord? Leave it unsaid and warn Chas of an alternative story? And if so, could I repeat the hypnotism as successfully another time? I decided to go for the easy option and say nothing. I invited Chas to dinner again the following Saturday but warned him to act as if nothing had happened. Before Saturday came I purchased a tube of sexual lubricant. He turned up at around six thirty. This time he had an overnight bag as I'd suggested he might like to stay, and he'd jumped at the chance. I poured us a beer then Carole came in from the kitchen. When she saw Chas she seemed a little abashed and went a bit pink. I asked if she was all right, thinking that maybe she had remembered Chas' previous visit. She said she was, and after a bit of wheedling by us said that she'd dreamt about Chas last week. When we pressed her she went coy and admitted that it was a bit rude, but would say no more. She had a drink and went to change out of the clothes she'd been in all day while we laid the table and opened the wine. She came back into the room wearing the short skirt, but with a soft dark red silk top with a deep neckline and buttoned front. The movement underneath as she walked showed us quite clearly that she was again wearing no bra. Even better was when she bent forward to serve us dinner. The cleavage was tantalising. As dinner progressed and the drink went down she "absent-mindedly" undid the top button, allowing the top inch of the material to fall away from her breast. A little later she undid the next, exposing even more of her tits. As she moved now, each breast threatened to escape but did not quite succeed. Over coffee the third button undid spontaneously, due no doubt to the pressure, and shortly afterwards her aureolae were peeking out. Finally, as she reached out for her glass of Tia Maria her right breast popped out completely. Chas and I said nothing, just stared; she smiled and carried on as though nothing had happened. Then I could stand it no longer. I went behind her chair, reached round her and took her boob in my hand, bouncing it gently up and down. Chas came around and took the other, while Carole sat there with an even bigger smile on her face. "That's the sort of thing I've been dreaming about" she said. So I had no need to hypnotise her again. It seems that the post-hypnotic suggestion was still working. We went on to another evening of sexual excess, but this time Chas did not have to leave halfway through, and Carole remembered every detail afterwards. The lubricant came in very useful, assisting both Chas and I in forcing entry at the same time - but not in the same orifice. This time she was not only as willing to give head and swallow as before but also to take it up the arse although my prick was the only one that would fit in there. Chas stayed in our bed overnight and twice during the night I awoke to find them copulating. The first time I joined in, but on the second I was too shagged out and let them get on with it, going back to sleep. Carole got up for her morning pee, and when she returned she told us that her fanny and insides felt the same as the previous week, and asked us to explain why that should be. We had no option but to confess what had happened. Although she had difficulty believing it she had to accept that she must have had Chas inside her and just not remembered it as this would certainly have awoken her had she just been asleep. She didn't complain all that much, though, but insisted that if I hypnotised her again I would not make her forget it. Then we showered, had some breakfast and got back to shagging. By the time Chas left after lunch Carole was hardly able to stand having been penetrated at least a dozen times in eighteen hours. Chas now visits every month or so, despite having a regular girlfriend.
