I was 17 years old when this happened. P.S. the age of consent in UK is 16. I was working part time in a grocers store for pocket money before starting full time work. It was hard work, but also fun. A lot of the women shoppers and some of the daughters would flirt with me and the under manager Roger. Also one of the other staff members Eileen would also flirt with the male customers and with Roger. It was late June and the days and nights were hot. Lots of skimpy clothing, I really enjoyed the ladies. It was a Friday early evening and I was about to finish up and go home. Eileen was at the till having her shopping totaled up and getting her 10% discount. Roger was on the till and was flirting with Eileen. Nothing new there. She had 4 very large bags and as I was about to leave she called over to me asking for my help. Now Eileen was in her early forties, Long black hair, a little too much makeup long shapely legs and a hell of a chest. She had a older, but pretty face. . I went to see what Eileen wanted me to help with when she asked could I carry two of the bags for her to her house. She lived very close to the shop, so it was no real imposition, and I agreed. As I picked up the bags Roger winked at me and nodded his head. I was confused and wondered what he meant. A few minutes later Eileen opened the front door and instructed me to go through to the kitchen and put the bags on the work surface. I did and as I turned Eileen was on her knees right in front of me and in one swift lunge she pulled both my shorts and under pants down past my knees. Like a vacuum pipe she latched onto my cock with her mouth sucking my soft cock into her mouth. This was only the second time that I had my cock sucked. I was stiff as an iron bar in seconds. I was no virgin, Maria was the first girl to suck me, Debora was the first girl that let me touch her tits and fanny and Sandra and Julia were the first two girls to let me fuck them. At this time I had never sucked fanny, or have any sexual interaction with a Voluptuous woman. At first I could not believe that a woman like this would want a lad my age, after all she had a 15 year old daughter. The thought of the daughter or her husband walking in on me had my dick starting to wilt. She asked what the problem was. I told her I was worried about her family catching us. She laughed and told me that they were both away for the weekend. My dick sprang back to life and promptly spewed a load of love juice down her throat. Once she had dispatched my load she dragged me by my dick up stairs and into a bedroom. there she pushed me backwards onto the bed and straddled me pinning me to the bed. Within seconds she had her pink blouse off and was reaching behind to unfasten her bra. Out fell a pair of 40DD's and they were now covering and smothering my face. I lay there thinking what a way to die. She moved cupping one giant orb and directing the nipple to my mouth. I knew what she wanted and licked and sucked the nipple and breast before moving on to the other one. It was like going to heaven. Unbeknown to me she had undone her skirt and stood up and took the skirt off. he hadn't any panties and her thick bush of black hair was on full view. I thought, well the curtains and carpets matched and she's not a bottled black haired woman, it's all real. As I mused over this she had settled back on top of me and was slowly sinking down my stiff pole. She was hot not just down there, but in the way she was behaving. Having blown one load I was able to lasted a long time. Eileen rode like a maniac trying to rip my cock and balls from me with her pussy. She moaned and groaned so loud I thought the neighbors would hear. Eventually with a final groan she stiffened and then fell forwards onto me with those giant orbs across my face. As she recovered she realized that I hadn't and was still hard inside her. She told me what a good boy I had been and now I was to screw her from behind. She was quickly up on all fours on the bed waiting for me to mount her. I had never fucked in doggy position before, but I knew what was to be done. I mounted her and slammed into her hard. She told me that was how she wanted it hard and fast. It was not the tightest fanny I had ever had and I slipped out several times to load groans. The oooohs and aaahs came again once back inside her. We fucked for what seemed hours before I came. I suddenly realized what the time was, my mum would be expecting me home for tea. Eileen told me to come back after tea and let myself in the back door. On my return she was naked except for a flimsy negligee that hid nothing. I went to grab her. She pushed me away telling me that I had to agree to some ground rules before anything else would happen. the rules were:- 1) I must never tell anyone about what had and would happen. 2) After this weekend It would never happen again. 3) I must act natural with her so not to give anything away. 4) I must do everything she asked. I immediately agreed. She escorted me back to the bedroom. As she lay down on the bed she instructed me how she wanted me to lick her clit and fanny. This was new to me and she had to give me guidance and even pull and push my head to where she wanted attention. It tasted good. Then she rolled over onto all fours and I thought she wanted more doggy fucking, but no she instructed me to rim her arse hole. From all the moans and groans and occasional squeals I must have been getting it right. Then she moved again and ended with her on top of me and told me how to 69 with her. It was terrific. I almost cum. She then got us into the spoon position and we made slow passionate love for ages until I came deep inside of her. She had me lick her out and clean her up. By this time I was hard again, and this time she did want more in the doggy position. I pounded her with slow hard and deep thrusts. I felt and heard her come several times. Then I emptied my balls again in her hot wet slippery fanny. We lay for ages cooling down and talking. I was pleased with myself when she told me that I was one of the best she had ever had. By this time it was late and although I protested about going home she reminded me that there was two more days to the weekend and if is was going to last the weekend I would need to recover my strength. Over the weekend she showed me so many things. From liking fanny and arse holes, to loads of different positions. For a woman more than double my age she had stamina and was very flexible. We did anal which was another first for me. By the end of the weekend I was shattered. I really thought I was in love with this woman. She reminded me that it would never happen again and then sent me home. My mom thought I was going down with something. Back at work, Roger just kept grinning at me. Did he know? Had it happened to him? I will never know. What I do know that I now loved women and girls of all ages.
