Staying late for work[MF][Cheating]

So I had been talking to a co workers wife for some time. We had started talking at a work gathering, and had ended up with each others cell phone numbers that night. Fast forward about three weeks…
We agreed we would tell our significant others that we were working late, and met up near one of the stores on base(We were both Marines). She climbed into my jeep, and we headed for the beach on base. Once there, I put the jeep into four wheel drive, and took one of the Dune sand roads to a little hidden parking spot on the water(land side), and surrounded by trees. I had fished here before, and knew that you could, and usually did, go all day without anyone bothering you. The entire drive there we made small talk, nor really letting the conversation get too dirty.
Once parked, we moved to the back seat of the Jeep and kept talking. After a few minutes, she looked at me and said “So, why are our clothes still on?” That was all I needed to hear, to quickly take my boots, pants, and top(s) off. She did the same, finishing before me, and while I was taking my undershirt off(last article of clothing) she reached over, and grabbed my already hard shaft and started stroking.
Once I joined her being naked, she straddled my lap, and started making out. I’m 6’1, and about 190 pounds at this point. She was about 5’4, maybe 110 pounds. We are Marines, so we were both very fit. She took this opportunity to grind her pussy into my shaft, getting noticeably wetter with every slide. Her perky B cup breasts were right in my face, and I had no problem slowly licking, then sucking, then nibbling on her nipples, as she brought her hips up high, and finally lowered herself down onto me. She rocked her hips back and forth, and I could feel her stretching to take my length. She was so tight and wet and withing a few minutes, I felt her lips quiver, and her torso start to tighten as she came. She didn’t stop, only slowed down, and kept grinding. After another 5 or so minutes, she said she wanted me to bend her over, and, seeing there being no way to do it in the back of the Jeep, I opened the door, and slid out, pulling her out, then bending her over, so her torso was in the back seat, and started fucking her there. Her hips popping back was such a tight, and massaging position to my shaft, that after a few minutes, I already felt myself swelling, getting ready to cum. I said I was about to cum, and she looked back at me, smiled, and said “Deep, fill me with your cum Sergeant.” A few thrusts later, and I slammed my hips against her ass, and let out a large, long load, filling her squirt after squirt,until I stopped throbbing. We took a minute to catch our breath, then got our uniforms back on, and started to head back to the parking lot she left her car. On the way there, still on the back roads between the beach and main side, she leaned over, and pulled me out, sucking all my cum and her pussy juices off of my shaft. We got to the parking lot, shared a quick kiss, then she got in her car and left.
We carried on a affair for about 9 months, before stopping seeing each other. A year later, we started again for a few months, then stopped for good. I still talk to her a few times a week, but she is happily married now.
