Last winter I was doing a tiling job for a friend, I knew his missus worked overseas she was a part owner to a administration company. Kev had briefed me on his job plan and I got stuck in , he told me his wife would be back . She arrived early afternoon Sherrie was a looker , she was happy with the plan , the job was to be finished but there was a delivery delay with there tiles . I worked until Kev got home I left sharpish leaving the love birds to get reacquainted , they knew I was leaving , they wanted me to join them but I made an excuse and left . The next few days the job started taking shape , Kev messaged me saying he had to go to Birmingham for a meeting and would be back late he asked would I stay and keep Sherrie company , as I live by myself I said ok . He spoke to her and Sherrie teased me saying I was her dinner date , I cleaned up , steak and chips with a nice bottle of wine , the food was good and conversation was very topical . The wine was going down well , I asked if she had anything stronger , 2 large whiskeys followed . She was getting typsy and said I know you left early the other day so me and Kev could catch up , she said you should have stayed , Kev went to bed early alone. She said they had a open relationship , she would pick up men or escorts , it good for us both. She started flirting with me , I felt a bit uncomfortable as she’s married , she went to the loo and on returning said I’ve just been given the green light from Kev , if your up for it it’s all ok . I couldn’t believe it , we kissed , groped then into the bedroom we stripped off and got in bed , she was vocal telling me what she likes and what to do , she loved me licking her pussy and nibbling her nipples , she wasn’t a stranger to sucking cock , then she got on all 4s and ordered me to fuck her deep , she reached under to rub her clit as I banged her , a few arse slaps and she wanted more . We changed positions her on her back she had hold of her legs as I fucked her , she was loving it , she ordered me to lick and frig her pussy and clit as she worked her nipples with her eyes closed , she wanted to see me tongue on her clit as I sucked . She grabbed my head and controlled me until she came with a arched back , I dived straight in fucking her , I knew I was going to cum she said I want it on my tits , I pulled out wanking and I shot my load . She said I needed that we sorted ourselves out and went down stairs for another drink , when Kev came home I was a bit sheepish, they kissed and he said he was going to change out of his working clothes. Then Sherrie hit me with a bombshell she said Kev didn’t give me the ok for you to fuck me but I’m glad you did. I was not happy , she said I won’t say anything but I want more. Kev thanked me entertaining his wife , she said he’s got a few hidden talents, and then she offered me more work in their house. I left saying my goodbyes , the next day finishing off the job and she treated me to a sloppy BJ.
