Trekking in Nepal

This memory is from a couple of years ago, when I was a single man working abroad. I was trekking in Nepal, just me and my guide, for 1 week. After a couple of days in the nature, we stop for the night in a small hotel in the mountains. We arrived in the afternoon and we were the only ones, the guide took a small shared room at the ground floor, I took a small tiny room just for myself at the 2nd (and last) floor. The hotel was really a basic one, 1 toilet each floor and no hot water, almost no lamps in the bedrooms. After a coupe of hours arrived a big mixed group of noisy students from UK, around age 18. I spent the dinner in the kitchen with the owners, as I wanted to avoid the noisy talks from that young group (I think they were around 20 including the teachers). After dinner I went back to my room, as we had the plan to wake up really early. In the room beside me, there were a group of girls from UK, that was talking together. The boys were on the 1st floor, I think just to keep things safe from hormones. Though the thin wall, it seemed to me they were talking about their masturbation during this travel. Or so I thought, because it was hard to spend the whole day in the nature without any occasion to touch myself. Neverthelss, they were tired and said tonight each other, that's when I heard a little moan from the girl just on the other side of the wall, probably because of the cold sheets. During the night I woke up because I heard a clear sound of fast rubbing of the sheets of the bed just opposite the wall. I still remember today that sound. I start to get a boner and decide to masturbate - and I let her know from some noise. As soon as she realise I'm masturbating, she reaches an orgasm. Quite soon I also have a huge load of sperm in my boxers. We both continue to masturbate and letting the other person know by the soft noises of the sheets rubbed and by little moans.  We both had another orgasm and continue to rub. After a while, I put a foot on the wall to let her know that I'm close to her; this must get over excited as I hear the sound of something hitting the floor and waking up all the other girls in the room. It ends in this way, I hear her saying she moved because of the throat ache; after a while it's clear that the chemistry is gone because we don't have an opportunity to continue together. The next morning I didn't have the chance to see her, as we went in different directions; however I clearly remember passing by their room and sniffing a strong pussy flavour... I wish I could take her panties! In the next days I needed to touch myself every night. Even now, as I write here, I sense an urgency to touch myself. This was my first real experience where I heard a girl masturbating, but thankfully it was not the only one. I will share more of them in the future. Hope you enjoy my first submission!
