Night watch

I'd been working with Sue for about 18 months, we'd always been friendly, laughing and joking. Both married but in the military. Back when this happened you could get kicked out for having an affair.
I lived in married quarters with my sexually conservative wife, she in the single accommodation as she was on an unaccompanied posting.
As I said we got along well. We'd been informed they'd be a Squadron photo, best uniform etc. Well Sue was a Wren, so she turned up in her best naval uniform, me in my best Army one.
She kept getting asked if she had service issue stockings and suspenders on, which she ignored. Then one guy stepped over the line and tried to feel! He wouldn't take no for an answer, so being the gentleman I am, I stepped in told him to behave. I thought nothing more about it. I later found out she had and had wanted me to find out!
One evening, I was on a night watch taking over from Sue and she'd forgotten to get the evenings rations from the cookhouse but said she'd bring them up later.
She turned up around 9pm, in jeans and a tight fitting t-shirt, hair down and looking stunning. I'd always had a soft spot for her, but she was out of bounds, or so I thought.
The evening watch was always quiet, and we watched TV together for a while. The she said she'd best get off, as she was relieving me in the morning. We got up and there was that moment that happens, we brushed past each other felt that tingle of excitement and both stopped dead still.
What happened next was the beginning of a 9 month affair.
We just fell into each other's arms, kissed passionately, broke away and again stood dead still.
I broke the silence, Sue we shouldn't do this,we should be sensible, you should leave but I don't want you to. I've fantasised about this since I joined the unit. She said that she'd done the same. But we had to be so careful.
We sat down, started to discuss everything, she telling me she'd think of me while she played with herself, making herself wet, finger fucking herself to orgasm thinking of me. I told her how I'd jerk myself off thinking of being with her in the very office we were in.
We kissed again, she then stood and said "fuck me, make me cum, I need to feel you inside me". We dropped our trousers and pants, she sat on the corner of one of the desks, I rubbed her wet pussy, inserted one then two fingers, and made her cum. I dropped to my knees and licked her sweet love juices. She came again. I stood, rubbing her clit with my rock hard cock. It slipped inside her, and I fucked her hard and furiously. As she asked for more. I didn't stop, I shot my load and carried on until my cock fell out of her pussy. Now it was my turn to sit on the desk, she put my soft cock in her mouth, expertly made me hard again then led me to the office sofa where she sat on me and rode me like nothing I'd had before or ever had since. She came again, and when I did it was the most powerful orgasm I can remember.
We stayed in that position for a long time, recovering, talking softly, kissing gently. When she finally got off me we realised 90minutes had passed and she was late for block curfew. We made up the story that I was so busy she'd have to stay most of the shift. She left around 3am but not before we'd made love again.

I never got to undress her fully that night, but if you want to know how that happened leave a comment.
