Young soldier

Being a young soldier, not yet 18, I was stationed near my father's family. Some weekends I'd leave my base and go and stay with one of my Dad's cousins, M. She would have been late 40's, widowed.
Having visited a couple of times we were becoming comfortable with each other. If we crossed on the landing while heading to the bathroom, she in a nighty, me in boxer shorts, it was normal, no attempt to cover up etc.
We'd been out on a Friday evening, to a working men's club, on the way home we grabbed a fish supper. While waiting in the cue, two girls started fighting, full on, punching, slapping, pulling hair. I was about to step in when M stopped me. Told me not to get involved.
We ate our fish and chips back in the house, poured a beer each and started chatting.
M told me about another of Dad's cousins, J, who was having an affair with a much younger guy. This wasn't a huge surprise, as she'd made a pass at me when I was 15!
M said J was telling her about this guy, how the sex was so good, how it made here feel alive again.
I asked M if she would start dating, having lost her husband 3 years ago. Yes, J made her pass at me at his funeral!
M said she would when the time was right but just now all she would like is some fun. I, full of bravado, said I'm sure that can arranged! You're an attractive lady, fit body, great arse. She was shocked, so was I really as I'd never thought of M as anything other than an Aunt. I could feel my cock starting to twitch.
We had the 'do you think so' conversation, where I told her she looked fantastic in her nighties. She stood up to get another beer and I did something I never thought I do, I tapped her bum, said there a beautiful peach of a bum. She turned and pretended to tell me off, saying you shouldn't touch what you can't afford. I replied, perhaps better take out a loan then!
She got the beers and sat down closer to me, I could sense something was going to happen. After a few minutes she asked if I really did find her attractive, I of course replied yes. She put her hand on my thigh, gave a little squeeze and then rubbed. My cock sprang to attention, impossible to hide, M smiled and said oh I've still got something if that's the affect I'm having.
I put my hand on her thigh, she parted her legs just enough for my to reach her inner thigh. I stroked my way up a little higher, turned to face her, we kissed gently then more passionately and then we slipped off the sofa onto the floor. One of my hands undid a couple of buttons on her blouse, the other lifting her skirt to reveal a pair of black lacey knickers, now with a growing wet patch! Her bra was a match but didn't stay on long. I held one of her tits while sucking on the other. Her nipples were rock hard, she was moaning telling me to suck harder, suck harder.
She realised I wasn't that experienced with sex and started to guide me. She slid out of her skirt, leaving her knickers on, helped me remove my clothes. I was laying there totally naked, M playing with my rock hard cock, licking the precum off her fingers. She then guided my hand between her thighs, showed me what to do, how to move. She told me to watch her, she found her clit, showed me how she liked to play with herself and that I should copy the movements. She then told me how to find her G spot, use two fingers, not to ram them in and out but to flex them up and down when inside her.
She let me play, let me practice, let me understand what a women needs. She came heavily, shuddering, squeezing my hand between her thighs making sure I didn't move. She relaxed, panting, sweating and wanting more. She instructed me on how to eat pussy. I went down on her, my first pussy session, it was wonderful. I tasted her for the first time, licking and sucking on her clit, I put two fingers inside her, played for a few minutes before she came again, this time pushing my head deeper into her pussy.
She then sat on me, rode my cock, came again, I came like never before. I held on to her making sure the moment lasted for as long as possible.
This was first of many sexual encounters with M, and then there J, but more about that later.

But what a way to lose you virginity! Yes, M was my first and never forgotten. Even now nearly 40 years on we still talk about our summer of sex.
