I was simply pushing a trolley around the aisles of the supermarket doing the usual weekly shop when I heard someone say " Hi Viv, how are you ? " I turned and saw Derek, an acquaintance rather than a friend, that I had not seen for ages . I used to go to classes with his wife, now ex wife , before she went off with another man. We started chatting, he asked about my husband so I explained that I was now separated, but my husband had turned nasty about the split. The fact is I was uncomfortable about chatting to Derek as I knew my husband was spying on me, sometimes following me, and often accusing me of having affairs that had never happened. For all I knew my husband could have been in the supermarket right then. Derek sensed me being ill at ease. I explained why, but said I would love to catch up and talk. He suggested that we finish our shopping then meet up at his house , if I was sure I was not being followed. An hour later we were in his lounge drinking coffee . I commented that he looked well. The last time I had seen him he had lost a lot of weight after being hospitalised , and looked pale and weak. Now he had good colour in his cheeks, looked fit and strong. He answered that I had lost some weight , which was true, but added the comment " luckily not where it matters " . He was nodding towards my breasts , which are large. Although I was secretly flattered and took it as a compliment, I still chided him . " You cheeky swine ! So you're a tits man are you, I never knew " . " Not really " he replied " but I always had a thing about yours. " " You never let on " I answered. " Well, what with you being a respectable married lady you would have taken offence, ." " I might not have " I said, " I might have liked the compliment . Even respectable married ladies like to be noticed . " " Yes but if you had not been offended, I would have tried to take it further, you would certainly have said no . " I knew I should have changed the subject , but my brain was saying ' he wanted to get you into bed ' and my hormones were saying ' he fancies you ' . I was also aware of a tingling in my nipples and a wetness in my pussy. I am a respectable lady, I don't have sex just like that , for quite a while I had not had sex at all. " I am saying yes , now " . That was it, we were kissing intimately, his hand was down inside my panties exploring my vagina while I was rubbing his erection through his trousers. He had got me so turned on I was grinding my pussy against his hand like a dog rubbing on someone's leg. As unladylike a sight as ever was seen, me urging him on , him using all his force to hold me in place. My orgasm was so intense I was out of control, I could feel my secretions trickling down my legs. When I was through it he undressed me with a passion, leaving me no time to be embarrassed about my tatty underwear. I was pulled to the floor, my legs lifted up, then his erection pushed in to the hilt. I do not like rough sex , usually , but I wanted it then. To be pounded , to be fucked into satisfaction. My second orgasm followed quickly, and I knew Derek was pumping his juice into me. He was limp on top of me , then rolled to one side. He was looking at me with warmth and desire, then kissing me gently, then touching me softly . His lips were playing my nipples, then kissing down to my belly button, across my belly, and down to my pussy. His tongue touched my clit and I was away again. I was forcing his head into my crotch, telling him to tongue me. Another overwhelming orgasm left me weak with pleasure. Derek was kissing my lips, his mouth and tongue tasted salty. I knew it was the flavour of his cum. I am a respectable lady, I do not let my man cum in my mouth , or not until that day. I dipped my fingers into my pussy , and put them into my mouth, then made him kiss me again. He put his fingers in my pussy, then into his mouth, then kissed me again. I could tell that his cock was starting to harden again so I took control. I pushed him onto his back and took his cock into my mouth, and no longer being a respectable lady, I licked and sucked him back to hardness. Next I mounted his erection and rode it for all I was worth while he played with my breasts, which he had so much wanted to do. I did not go back to my house that day, nor that night. I did not even get dressed . 24 hours of impromptu lust , as intimate as two adults could be. When eventually it was time to go I felt like a new person, I felt desirable , attractive and sexy. From that day I never again went to the supermarket in tatty underwear, now I always dress up, just in case.
