It was circa 2008, middle of the week, a dark, drizzly January day. I had met up with my ex, and we drove to a large regional park. We found a deserted dirt parking lot under the canopy of some large trees. There were a few parked cars, but we had our own area away from everyone.

I had a camper shell on my truck, and my bed was lined with plywood, carpet pad, and a berber rug. I had a couple of blankets and a pillow that I kept in a box, as I would sometimes nap, during my lunch hour. Anyway, it wasn't long until we were in the back and making out...and making good use of the pillow.

We were both married, but not to each other. This was a 'for old times' sake' type of reunion.

The berber wasn't something you'd want to fuck on, so the blanket wound up beneath us. There wasn't much headroom, so I was on top, missionary style.

At some point I either heard or sensed something, and I turned my head and looked behind me. There was a fucking perv standing next to my truck, totally staring in the window. I just yelled 'what the fuck?!' at him, and he ran off, in embarrassment. My ex kinda sat up and saw him run away.

She didn't mind too much, and we just went back at it! She had two massive, panting, squeezing her tits until her nipples were long enough to poke my eyes out, orgasms.
