3RD Experience

This happened on a camping trip with school in Year 9 I think (You've probably gathered by now that my memory for dates is abysmal, bear with me.); we'd walk with groups of friends during the day to the next campsite and then pitch up for the night, all with teachers supervising us. One of the days was shocking; torrential rain, hail, wind, thunder, you name it, we had it. We all got to the camp and we're all grumpy as fuck and pitch the tent as quick as possible. I ended up sharing with only 1 other lad, so it was just me and him in the tent, trying to get warm and dry. This of course involved getting naked to put warm clothes on, which was fine in its self, because we both did it in our sleeping bags. Of course, in the process, I got hard. Like really hard, and REALLY horny. I started up a conversation about porn, reminding him of how he'd said he'd bring some porn for us to look at, which he hadn't brought. So I say "Shit, I'm already hard haha".
Him: "Hah, me too a bit" - This is where impulse and lust took over for me. I say something along the lines of "Show me then.". He kinda laughs nervously, I put my hand on his groin area through his sleeping bag and drag it back teasingly. He does the same. I unzip my sleeping bag and pull my pants down and my erection is like a fucking steel pipe, and grab his groin again, and then unzip his bag. I cop a feel through his pants, he's not hard, but I'm not deterred. I give him a rub and massage on his dick, and he cops a quick feel at mine before retreating again. I pull his pants down and go down on him trying to make him hard. He doesn't get hard. He says "You won't get me hard" halfway through me sucking him off. (Ouch.) So I give up and pull off. I then ask him whether I can try fucking him. He kinda just smiles like a dork, but doesn't say no when I turn him over on his front and lifts his arse up. All this time, people were walking past the tent and chatting in their own tents a few metres away, it was hot thinking of that, the prospect of getting caught.
So I give my dick a few yanks with a spit-lubed hand and then line myself up and push myself just through his arsecrack and I get paranoid, thinking I can feel I'm pushing myself into some shit so I pull out sharpish saying I couldn't do it. Thinking back it was probably just sweat from being in a warm sleeping bag in a now warm tent but this didn't occur to me at the time. So I lie back down on my sleeping back, and he cops another quick feel before completley hibernating in his sleeping bag for the night, leaving me with a massive boner and nothing to get me off. A few beatings and I was finished all over my chest. Cleaned up with a wet-wipe, put it in a baggie to bin tomorrow, zipped up and went to sleep. Next day was surprisingly not awkward. I texted him about it a couple of days later when we were back at school and he told me to forget about it. That's how we left it.
