Most of our recent change in our sex life has come about by alcohol and spontaneous liaison. Nothing planned which my wife enjoys. She finds the planning a little tacky as she calls it. Our recent experience however was something very new and totally unplanned, at least part of it. It started one evening when i was horny as hell but my wife was not, so she promised that in the morning she would make up for it. We were both up quite early and showered and waiting for the water meter man to install our new smart meter. He was due at 9.40 so I came down stairs to let him in while Susie was choosing what to wear. (she knows I'm a sucker for stockings) 10.40 and still no caller so we started our time together. Susie was in great form and knows that using her nails gently on my balls by my arse is a real turn on. For my part i was finger fucking her and she was very wet and soon straddled my cock which she loves. In no time at all she had her first orgasm and was rocking away for more when the doorbell rang. Our first reaction was bollocks to it but after a repeating ringing and knocking I said hang on I will go. Susie just turned over and looked so fuckable with high cut satin pants stockings and a very low cut bra holding her c cup in, just. I answered the door and it was the water meter man who apologised for being late but said it will only take about 20 mins to fit. I said ok and went up to see Susie and explain but at the same time tell her it was a big black guy about 45 or so. The guy was a miserable sod and hardly spoke a word other that he would need access to the meter and boiler and power. The meter is in the garage behind all sorts of crap so off i trots to sort that out and get rid of him asap. 10 minutes later i return and susie is in the kitchen in a white dressing gown and her black stockings showing she was dressing or undressing. She still had lipstick on and looked like she was preparing for an evening out which of course was almost the truth. As i took the guy out to show him the access point he asked if I could move more stuff. Bollocks. I went back inside and Susie was on a stool in the kitchen and you could clearly see her stocking tops via her opened dressing gown and plenty of lace bra through the gown. The guy was now talking and had clearly noticed her underwear, which she made no attempt to hide. For my part i'm now back in the garage yanking stuff out the way. About 5 minutes passed and I returned to the kitchen and now he was leaning against the worktop talking to Susie and it was clear he must have been wearing boxer shorts as there was a clear long semi in his trousers. He knew that it was showing and Susie had very definitely noticed and had moved slightly to let more cleavage show. She even moved slightly to let more leg and suspender show. I had walked back in to an electric atmosphere and he looked back to judge my reaction and in turn I looked at Susie who blurted out that we were just about to have some fun when he arrived. The guy said well don't let me stop you and run his hand down his cock which looked thick and long. To ease the situation and let it take a course i said give me 2 minutes to finish the garage and sneakily went upstairs to switch on a go pro camera on the window sill and retreated back to the garage for about 10 mins. Susie took this cue to have fun and took him upstairs and took off her dressing gown to reveal a stunning fuck puppet of a woman. He took off his top and dropped his trousers and unleashed a good long solid black cock, Susie's first. She dropped to her knees and just played with it and got him very hard and by know she was sucking and licking it and using her nails on his balls. He lifted her up and plonked her on the bed and inserted his cock into her slowly. Susie was fucking loving it and soon had her 2nd orgasm of the day and he was still only half way in. She lay on the bed and asked him to let her ride him with he duly did and boy did she ride him and still he was not all the way in side her. At this point I joined the action and whilst i have a good hard cock he was simply much bigger rounder and harder. Susie asked me to help her take it all and would i fuck her arse as well (a first) I bent her forward slightly to access her from behind and loved the sight of this cock and as she leant forward I scrapped his balls as Susie could no longer reach, soon I had his shaft in my hand and bent over to lick and lube her bum and she moved to much and it came out and was right there in my face and it just seemed so natural to lick it and suck it and Susie came again while watching me. I was now enjoying my first cock and could taste Susie on his cock but she wanted more so soon she said just fuck me hard to which he turned her to missionary and fucked her with it all inside her and me holding his cock as he withdrew each time. This was too much and he came in less than a minute. He rolled over and Susie lay there with spunk oozing out and I licked her out like a dog licks a bone. At this point Mr chatty dresses and fishes his job in record time whilst we fucked again. The funniest part was the following day another guy came around to inspect the job and was clearly well informed of our previous day but alas he was not in luck.
