This is a true recollection of my first time with a woman (not a fumble in the dark with a girl of my own age lol) and how it came about. The lady in question was a friend's stepmum and although I'd known her a few years I never thought anything would happen but a bit of background to set the scene. My friend, Andre, and I often used to look at his Dad's porno mags when we at sixth form - the usual Fiesta, Razzle and that type of soft porn mag. One day we were reading the stories, perving the girls and both wanking which was something we'd started doing recently thinking that we were alone in the house. However, a voice from the doorway startled me and his stepmum called out "Andre make sure to put them back as you found them when you've both finished or your Dad will know." I was mortified and embarrassed but Andre said not to worry as his stepmum was really laid back about it. Needless to say I couldn't concentrate any more and made my excuses and left. A few month's later, with the embarrassing memory fading, I called round to see if Andre was about but only his stepmum was at home. She explained that he was playing golf with his Dad but asked me to come in anyway. Nervously I said yes and she poured me a cold drink and we chatted in the kitchen. She was charming and put me at ease and explained that I shouldn't have been embarrassed about what happened - "all young men do it" she laughed and I felt much more relaxed. As I relaxed I started to take more notice of her and realised how sexy, in a mum next door type of way, she was. Taller than me and willowy; long brown hair; wearing a camisole type top and long flowing skirt completed with strappy sandals. I started to feel aroused as we chatted and I kept glancing over at her and smiling awkwardly. "I know you enjoyed the magazines Mike but did Andre show you any pictures of me?" she asked. "No Mrs Ashcroft" I replied trying to take in the fact that my friend's stepmum might have be in a porno shoot. "It's Petra" she laughed "and if you're going to see pictures of me naked that's what you'll call me". "Yes Petra" I replied blushing. "Wait her and I'll get some" and a few moments later she was back with several magazines. "Come here and sit next to me" and moved to the sofa in the adjoining conservatory. Putting most of the magazines on the table she kept hold of a Fiesta and, going to the Readers' wives at the end she showed me pictures of her stripping and ending up with her naked apart from some black sussies and stockings showing off her taut pick nipples and her pussy topped by a very thin strip of hair. I felt like my cock was going to burst out of my trousers as I looked first at the pictures, then at Petra, then back to the pictures - "god you're gorgeous in those Petra." "Thank you Mike. Here's some more I know you won't have seen as we keep these somewhere that Andre doesn't know about" . With that she picked up a copy of Private (I'd seen the occasional one so I knew they were more hardcore) and opening it up she showed me a picture of her knelt down with a semi hard cock nuzzling her lips then another with a dildo just into her, now shaven, pussy. "I bet you'd love to wank over these Mike?" "Yes" I blurted out "but I wouldn't last long". "Show me" Petra whispered "I liked what I saw last time so don't be shy" and with that she unbuckled my belt, flipped the button open and eased my zip down. "Take them off and your pants and let me have a proper look at you". In a trance I stood up and eased my trousers and pants down and my cock sprang up as hard as I'd ever felt it. "Stay there Mike - that's so sexy" and in a flurry of hands her camisole top was discarded and her skirt was up round her hips showing off black lacy undies which were soon discarded too. "Have you ever been with a woman Mike ?" she asked softly all the time looking at me and smiling kindly. "No Petra" I stammered - "then we will both enjoy this" she said and with that she dipped her head forward and started to kiss my cock. Precum was oozing out and dripping like a tap and she licked and sucked it off my throbbing head. As one hand cupped my balls her mouth slid further down my cock and I could feel my balls tightening as she sucked gently and my body began to stiffen. Petra knew, like any woman would, that I was about to cum and she sucked and squeezed as she drained every drop from my cock and I began to soften. Blushing brightly I apologised and Petra sweetly smiled back and said " I expected nothing less for your first blow job. Now let's go to the bedroom and you can taste your first pussy and I can teach you some things that will stand you in good stead with girls your own age later on" Once in the bedroom we both stripped and she lay back, parted her thighs and invited me to get my face between her thighs. The musky aroma of her pussy was intoxicating and she deftly guided my fingers and tongue to the right spots to pleasure her. Under her expert guidance I was able to make her come by squeezing her mound together from above with one hand, fingering her slowly with the other and licking what I hoped was her clit. By now my cock was rock hard again and, after Petra's orgasm had subsided she urged me upwards and guided my cock into her blissfully sodden pussy. Despite my urge to pound away she talked me through a more enjoyable rhythm and then some equally enjoyable positions. As she straddled me cowgirl guiding my fingers to her nipples as she rubbed her clit I felt her pussy grip me hard as she moaned loudly which was enough to make me cum again. As we lay cuddling on the bed she explained that this was good fun as a one off but unlikely to be repeated. Petra explained that she enjoyed one offs - that was the thrill for her but she did say I was now quite well equipped to find myself, as she put it, "a horny young minx who would fuck my brains out". After showering, finishing off my drink and leaving I was left puzzling to myself what had just happened. A great introduction to sex and yes Petra's tuition has stood me in good stead.
