Not too detailed but one I've loved doing. A while back took a friend out on a trail after she broke up with her bf. She was pretty pissed so she wanted to drink and get her mind off things. I suggested we go on a hike when it was warm as hell and it was fun. Drinks, music and company kept her mind off things. Until we got to a part where it was dimly lit and the trail was the only place well lit, we discussed how people could fuck off trail and no one would see. That gave us ideas and we walked off trail.

She told me she'd wanna try but her ex was pretty vanilla and I being someone who loves to try, told her I'd do it. So she gave me a look and we both agreed. Making out came first before she was very into it and asked me to fuck her bending over. We tried for a bit and finally I finished inside her(she had an iud) and got back on the trail like nothing happened. This went on for a few weeks and it was just a friendly and fun way to let off steam
