I went round on the Saturday afternoon to see my mate Carl. On arriving at his house this wife Debra opened the door. She invited me in and we walked through to the back garden. Carl was lounging on a lounger catching some sun. Debra went back inside to get some more beers. I was just about to ask Carl about using his van, when his phone rang. He didn't look happy as he saw who it was. He apologized saying it was work. Then he said sorry mate I'm going to have to go. Debra had just returned to the garden and handed me a beer. "Sorry luv," he told Debra, "Got to go, I'll need my go bag." Then he was gone and we heard his car drive away. I know Carl is not able to talk about his work so I didn't ask, but Debra offered that Carl would most likely be away at least one night having taken his bag. Debra had brought two bottles each and we lay on the loungers drinking and talking. The sun had shifted, so Debra got up to move her lounger back into the sun. As she did so it was the first time that she was the sun side of me, and as she moved I could see right through her thin summery dress. There was no doubt in my mind that she was not wearing a bra or panties As she settled on her lounger again I told her that I could see through her dress. She laughed and said, "I hope you enjoyed what you saw." I told her that I definitely did. Debra is 5' 10" tall. She had long blond hair that almost reaches to her belly button, a gorgeous peachy bum and C tending towards D sized tits. All that and a pretty face that always smiled. It wasn't long before she was moving her lounger again. I thought it was before she needed to. Again I had a great view of her body through her dress. "You doing that to tease me?" I asked. Might be was all she said. Then she stood and went indoors for two more beers. She spent longer than necessary bending down to hand me a beer. I had a great view down her dress at her tits dangling as she bent forward. As she straightened she asked, "Like that did you?" My cock could have answered for me, but I replied that I had. After the beers the sun had moved beyond where we could place the loungers, Debra suggested that we went inside. She also asked did I want to stay for my tea. Debra got out some stuff to make sandwiches, and while she made some tea, I buttered some bread and filled the slices with some ham. Their kitchen isn't very wide but long. As I went to pass Debra she stepped back and we collided and I grabbed her to stop myself from falling. I found that I had a hand on her hips and my other hand on a nice large tit. As soon as my balance was stable I let go and stood apologizing. Debra just laughed and said, "You enjoyed that. You have been wanting to get your hands on my tits all afternoon. I could feel my cock hard against my trousers as I told her that I had enjoyed holding her but it was an accident. Then with no warning Debra pulled the two straps off her shoulders and the front of the dress fell to her waist. "Well you could get a better feel now," Debra informed me. Now my cock was getting uncomfortable. She took a step towards me and were were just inches apart. I was torn, this was my best mates wife, yet I wanted to grab those tits and rub my face between them. Debra made the decision for me by grabbing my hand and putting it on her breast. It was big, warm, smooth and wonderful. The nipple was hard against my hand. "Now you have got it what do you want to do with it," she asked. I was beyond worrying about Carl and dipped my head and rubbed it between her tits before sucking one and then the other nipples in my mouth. The nipples seemed to grow like my cock had grown. Debra had her hands in my hair holding it to her breasts. I had my hands on her arse, feeling it through the thin material. Debra groaned as I kneaded her arse cheek like you would a ball of dough. I knew her hands had left my head, but didn't know what she was doing. She must have undone the thin belt at the waist of her dress, because as her hands returned to my head the dress slid down and rucked up on my hands that were still on her arse.. I let go for a few seconds and the dress fell to the floor. Now I was holding her totally naked body. All thoughts of tea had vanished as my fingers on one hand slipped between her arse cheeks towards her pussy. My other hand was now between us and sliding down her stomach towards her pussy. I felt a tuft of pubic hair as my hand went lower and then her pussy. It was hot and wet already as I slipped two fingers into her pussy. Debra moaned as my fingers penetrated her pussy. Then her hips were thrusting at my fingers. My face was still glued to her tits whilst I played down below. Then Debra was pushing me away. I was worried for a few seconds wondering if this was going to spoil my relationship with Carl. I needn't have worried as Debra told me she wanted to get more comfortable. She led me upstairs to their bedroom and lay down on the bed. I now had my first look at her pussy and quickly noted that the collars and cuffs matched. Her pubes were just a shade gingery than her head hair. I stooped down and put my face between Debra's legs and took in the musk of her pussy. Then I probed it with my tongue. It tasted good and I was soon lapping and sucking her as she wriggled about on the bed due to the sensations my tongue was having on her pussy and clit. I was still fully dressed and my cock was giving me serious discomfort so with one hand on her tits, my tongue in her pussy, I was undoing my clothes with my one hand. I managed to take my shoes, sock, trousers and boxers off with just one hand whilst I continued to suck Debra's pussy and play with her tits. But now I needed more than just a muff dive, so I crawled up Debra's body and lined my cock up to her pussy. Debra took charge and grabbed my cock and steered and stuffed it into her own pussy, using own her feet, on my arse, to aid the process. Now fully deep, Debra was thrusting harder than I was to facilitate the pounding of her pussy. Her feet had now locked together behind me, trapping me in this state of heaven. We came pretty much at the same time and after disentanglement we were laid quietly kissing. It must have been twenty minutes or more and I could feel my cock beginning to stir again. I knew from earlier that Debra loved a good tongue lashing , so I pulled away and slipped back down her body and attacked her pussy again with my tongue. Debra was moaning long and loud. My cock was ready to go and I was in the throws of crawling back up her when she turned over. Seeing her peachy arse, I gave it a playful slap. The Oooh that left Debra's lips told me that she liked it, so I slapped the other cheek. "Aaaah. I'll give you two weeks to stop that," she said. Clearly she loved it. Instead of climbing on top I pulled her across my legs and rained three slaps, in quick succession, two on one cheek and the third on the other. Debra was rubbing and grinding her pussy against my legs as she gasped out more Oooohs and Aaaahs. This was causing my cock to throb with impatience to get back into her pussy. But I still landed four more slaps before pushing her off me. She was still on her front, so I straddled her legs and arse, lined up and thrust right up to my balls. Debra gave out a loud squeal as my cock penetrated her followed by a long sexy Ooooh. Then we were doing the dance of love again. Debra came twice to my once before we collapsed into a heap. It was some time before we disengaged and lay cuddling. We had been like this for just a few minutes when the phone rang and Debra reached for it and answered, "Hello dear. Yes. Yes. I understand. I know. Yes were in bed. OK," she said. I lay there and it suddenly hit me she had just said WE are in bed, not I am in bed. Then Debra handed me the phone. "Hi, sorry I had to rush, but I guess you were after the use of my van." Carl said. I told him I was. "If you look to your left on my night stand you will see the keys." he instructed and then asked to speak to Debra again. I looked to my left, after handing Debra the phone. He was right there was the van keys on the night stand. Then It dawned on me, how did he know it was to my right. Debra had blown a kiss and put the phone back on it's cradle. "Did you tell him we were in bed?" I asked. Debra laughed then told me she had, but he already knew as he was watching us on a security camera. Debra pointed to what I thought was just a fire detector, and next to a flashing red LED was a small black thing. "That's the camera," she informed me, "There's at least one in every room." I questioned every room and she nodded before telling me and two in the back garden and one in the front. I knew Carl was into his security as he had often told me that I should install some. The other thing that hit me was that I recognized the drone in the background on the call, Carl was on a plane. Debra confirmed that when she told me that Carl would be in Holland for at least three days. Was this an invitation for three nights of unfettered adultery I wondered. I didn't have ant time to think about it any more as Debra pulled me under the duvet and snuggled up tight to me. In the morning Debra dragged me into the shower room. As she turned on the water I suddenly became conscious of what she had told me about cameras the night before, and was looking directly at the fire detector. Debra saw me looking and told me not to worry and it was not on as the LED wasn't flashing. We lathered each other, then we were both so excited that we ended up on the floor fucking our brains out. Afterwards and when we were dry we went back to the bedroom. Debra slipped into a fresh dress, again no bra or panties. I dressed in my clothes from yesterday. Then in the hall we were kissing before I left with the van. I could see that the LED on the detector was flashing. Carl must be watching I thought. Later that afternoon I returned having finished with the van. Having given Debra the keys she invited me in and we lay on the loungers in the afternoon sun. Debra got totally naked and I was in just my shorts. I had scoped out and found the two cameras and one had a flashing LED. Was he watching? As we lay there I told Debra that the LED was flashing. She laughed and said that he could not only see, but also hear us. I asked wasn't she worried that he had seen us in bed. She was laughing again as she slid off her lounger and pulled my shorts down and took my cock into her mouth. Clearly by her actions she wasn't. As soon as my cock was hard enough she pulled me into the house and upstairs to the bedroom. She had me fuck her doggy style and slap her arse telling her she was a bad girl. I noticed that the LED was off. Debra loved it and besides being loud she thrust wildly back onto my cock as I thrust into her. We didn't last long. The rest of the day we fucked twice more. That night in bed we just kissed and cuddled. The next morning I had to be up early as I needed to go home before work. After fucking Debra and finally pulling away from her she told me that she would see me later as I dressed and left. I went to Debra's after work and took her out for a meal and on our return she fucked me as she pinned me down on the sofa. Laying there I noted that the detector wasn't flashing. We fucked again in bed before sleeping. I was up early as I had work and wanted to go home and change first. Debra was still asleep. I crept down stairs not wanting to wake her. I got to the bottom of the stairs when a voice asked, "Got the move done with the van?" I almost jumped out of my skin. There sat on the sofa, the very sofa Debra had fucked me on last night, was Carl. I told him I had done the move OK. Good he told me before thanking me for looking after Debra. I couldn't get out of there quick enough. Carl rang, later that day, to go for a few beers on Friday night. On Friday over beers he again thanked me for looking after Debra. He also said I was welcome to stay over whenever he was away. He had just given me permission to fuck his wife when he was away. It was strange drinking with a mate that I knew not only knew I had fucked his wife, but had watched and listened to us. It was nearly three weeks after that Debra rang me to say that Carl was away for at least four night and what was I doing.
