Fucking my girlfriend on top of a mountain [M21/F21]

I’m going to give a bit of context, so if you want to skip that and get down to the juicy stuff, look for the row of asterisks (********).

I’ve been together with my girlfriend Rebecca for about five and a half years now, we got together about halfway through our final year at high school and immediately formed a connection so strong that we decided it was worth the risk to go to the same university and move in together once we graduated. Neither of us had been in a particularly serious relationship before; I had had three previous girlfriends, none of whom lasted more than a couple of months, whereas she had one that went nearly a year, but at any rate, we were both virgins when we got together (second base was as far as I had ever gotten, third for her). That didn’t last long.
