Lovely capture!
Weird that a couple would do this in a place were there is minimal privacy. But
I guess they were feeling horny, so...
I went on a one-day 13-mile hike in Surrey, England with my ex once. At one point,
just off the path, there was old tree with branches that almost touched the ground
and surrounded the trunk in a kind of a dome-like shape.
So we got under the tree and took a short break while watching other walkers on the path,
a few metres away (they couldn't see us). Then we started messing about a bit, having a
kiss and a cuddle. Then my girlfriend pulled up her top and I had a quick suck of her titties
(she loved this), but nothing more than that. She tasted salty due to the sweat.
We got strange looks from a family when we got back on to the path. I saw one guy
peering into where we had come from, probably wondering what was so interesting
about the place we made into our temporary love nest.
