I discovered a new world of gadgetry at Christmas. Years ago I used to get my wife to turn on a small memo recorder, the type used by estate agents or professional people making notes for use later back at the office. It gave a new dimension to my desire to be involve in a remote way when she was playing with another guy. We had varying degrees of success and I did get to eavesdrop on their activities after the event so to speak. However the technology was limited and only good for a maximum of half an hour. The present systems are infinitely better and after a bit of exploring on the net, found some very sophisticated and far better gadgets to revisit the scenario of my wife carrying a device on one of her jaunts to have sex with another guy. A friend who was better informed on how to disguise a small device to enable crystal clear conversation from both parties. l Liz knew I liked her talking dirty and he showed me some speakers which could pick up a mouse farting. A disadvantage was that music or television noise would also be picked up, so a quiet room was required for best results and the device ran to a mobile {bluetooth}. The device was cunningly concealed in a locket around her neck but was extremely well concealed, Bond would have been proud. My friend also proudly boasted that cameras were available in the same size at a price. but i said knowing my luck it would finish up recording a view of a pillow and it swinging to and fro while she got fucked from behind, so I opted for the audio recording. A few days later it arrived, unbelievably neat and invisible in a lovely locket which had a man and woman in the throes of fun etched into the gold. A Christmas present which I gave on the morning before the family and grandkids turned up and the house descended into mayhem. She wore it on Christmas night and the quality was great. Running it on the laptop next morning, the gasps and whispers as we fucked were perfect. She had a date with a friend on boxing Day afternoon and I asked if she was happy to wear it. She said it would be fun and the lover was a chatty type so it might be a fun night when she returned. I saw her off as she drove to West Yorkshire for her meet at the north side of Leeds. Now back to my familiar role of remote cuckoldry, me wanking gently at home behind closed curtains while I explore in my mind what state of dress she is in, what he might be doing to her and she to him. Are they naked? Is he fucking her? filling her with spunk, or shooting it over her breasts. It was after eleven when she got back home. Walking in with a huge grin on her face, hair and clothing not quite as pristine as when she left, but that smell of recent sex as we kissed, the hint of saltiness in her mouth, a wet thong and stains on her stockings. Fantastic. I asked her to reveal all about her exploits. They had met at his local and had a nice light meal, sitting in a corner where they could whisper to each other. He was very vocal, the recording picked up the cutlery but also his voice saying he was going to fuck her brains out when he got her home. Liz asked how he was going to do that, goading him to turn her on even more. He boasted his cock was capable of multiple fucking and she would be well filled by each fuck. She told him she was looking forward to sucking his prick and letting him do what he wanted to her, her body was his for a whole afternoon and evening. They finished their meal and left in his car, leaving hers in the pub car park and driving the half mile to his house on the edge of the village. Overlooking fields and hills it was beautiful. The house was a climb down in size due to a divorce, but he was happy with his lot and said he felt it was a perfect shagging den. They went into his lounge and the conversation was stilted due to a long kissing session where he began to fondle her 34DD breasts, eventually removing both top and bra within five minutes. The sound of bristling clothing added authenticity as I listened and Liz obligingly stripped to keep her mode of dress up to the pace of the meeting. I listened again as he was clearly running his hand up her skirt and found her stockings and suspenders. 'Brilliant' he said, 'You have a wonderful body, I am going to fuck you so much, you are a dirty girl' Music to my ears and she took off her skirt, her panties were missing 'He kept them I am afraid' she said as I took in the matted tangle of pubic hair which carried heavy evidence of spunk. The half hour drive had more or less erradicated the taste of his come from her pussy, but it sort of lingered as I licked her as I listened to the conversation, Liz saying how nice it was being naked with him and how nice his foreskin felt, all smooth and his cock tasted lovely. He took her onto the end of his sofa and I caught Him asking her to turn round and suck him and then let him fuck her from behind. I marvelled at the clarity of sound even though she was stooped over his cock and sucking him, being told how good she was at sucking his cock and Liz replying that it was a nice cock to suck as she temporarily stopped sucking to let him know her enjoyment. She told me he sixty nined her for a while and then fucked her doggy style, most of the conversation descended into grunts and gasps as they satisfied each other and then when he was ready he told her to bend over the sofa arm and he fucked her hard and fast, spunking deep in her cunt for the first of four super orgasms. They went up to bed and she said, this wa where a recorder would have been useless but with the locket betwee both their voices, apart from when he got too close and the breathing distorted all else, it was fine. She adopted the sitting on cock approach, so keeping him at a reasonable distance and he was able to play with her hard nipples and breasts as she fucked him, him eventually coming for the second time after around an hour. They rested and he took some photos of her and they talked a bit before he got over her and fucked her missionary, giving her a long slow fuck. More talking and him asking if she would like to meet again and then she said they went back downstairs and he lit a log fire and they fucked in front of that. He came a fourth time but she said he was a bit weak by then and his come dribbled over her trimmed hair rather than exploding. But she said he had been a really nice guy and she would be happy having him fuck her again. I gave her my blessing and said her locket had been worth every penny.
