I was asked to lead a group of 9 young girls (11-12) and their teacher on a hike up a mountain in North Wales. About 2/3 of the way up, the teacher slipped and broke her ankle. Mountain rescue were very quick to come and take her off the mountain. The rest of the girls wanted to carry on to the top, so I said I would take them - it was a lovely summer day. We got to the top an hour later and sat down to take in the view. After a few minutes, one of the girls approached me and said; "Excuse me, sir but I need a pee!" I was about to say, 'go behind the nearest tree', when I suddenly realised... no trees, not even a sizeable rock for miles! I was about to tell her to go as best as she could right here, when I realised that this might make her the laughing stock of the other girls, so I said to all of them: "Is there anyone one who needs a pee?" No-one answered. "Is there anyone who will need a pee before we get back down the mountain in three hours time?" There was a certain amount of giggling... and half a dozen hands went up! "OK, girls, there's nowhere to pee but here, so you'd better all go here, now, together!" One impish little cutie piped up, "Are you going to go too, sir?" I blushed.. "Well, if you all do, so will I... OK now, all together, pull your pants down..." I found myself looking at 9 cute little pussies, squatting against the mountain top. One by one they started to pee, and I realised I had a huge hard on... "Come on sir", said the impish one, so I pulled it out and let rip, arcing my pee off the cliff in front of us... Impish one came up to me and took my dick in her mouth .... no, no, no! just getting carried away - she didn't do that! We all just got zipped up and went back down the mountain, but not before everyone agreed that what had happened would remain between us ... until now!
