This is actually a true story from my kinky youth. I was reminded of it by a conversation I had with a friend here recently, so I thought it might be worth sharing:

Sometime around when I was 15-16 my friends and I used to go swimming in a secluded pond that had a VERY muddy bottom. You could get to it by walking about 2 miles down the railroad track that went through our small town.

Anyway, one time when about 5 of us were swimming there I decided to take a break and just lie down in the dry area next to the pond. Next thing I knew the guys started picking up handfuls of mud and throwing them toward me. So I said something like "OK you can do that but you need to back off into the pond about 20 yards away". They did that and I lied face down and started to get plastered in mud, all over my back. So then one of the guys said that I needed to roll over face up, which I did. But when the mud looked like it was about to hit my face I would put my hands up to fend it off. Of course they didn't like this and said I needed to keep my hands away from my face. I tried to do that, but I couldn't resist covering my face when the mud balls got too close. Then one of the guys said something like "we should stake him out so he can't cover his face". At which point I just said "Ha ha, you don't have any stakes or rope to do that", which was true so I was off the hook. But somebody said "next time we come here I'll be sure to bring along stakes and rope". I honestly never thought that would happen and that they would quickly forget about it, so I just said that if somebody brought along the means to do it they could stake me out on the side of the pond and have at it.

So the next time we went down to the pond, about 2-3 weeks later, the guy who said he'd bring along stakes and rope was not with us, and indeed nobody was carrying anything like that with them. To be honest I wasn't sure whether to be relieved or disappointed, because the thought of being staked about and plastered with mud sounded rather exciting. Nobody said anything about the stake-out dare, including me, so I really thought they had forgotten about it.

Anyway, after we had been swimming in the pond for about 15-20 minutes, lo and behold the guy who said he'd bring along stakes and rope showed up -- wearing a backpack which turned out to be filled with stakes, rope, and a hammer!! Apparently this was all planned out because all 4 of the guys quickly jumped me, dragged me to the dry area beside the pond, removed my swimming trunks so I was now totally naked, and proceeded to hold me down, attach my wrists and ankles to the 4 stakes, and then pound the stakes into the ground spreading me out into a classic spread-eagle. Each of the stakes had a short section of rope pre attached with a tight noose knot at the end, so this had been well thought out for them to quickly overpower me and stake me out!!

I really could NOT move in this position, and I was feeling amazingly vulnerable and a bit scared. I had played kinky games with these guys before, but they were usually more like one-on-one, and I was NEVER the sole victim to be tormented by 4 guys before. As they had done 2-3 weeks before they all backed out into the pond and started to pick up handfuls of mud and heave them at me. But this time I couldn't block the mud from hitting my face, or my cock and balls, and indeed I got plastered quite mercilessly. It's hard to explain how vulnerable this made me feel, knowing that I was totally defenseless to getting covered head to toe in mud!! The first few mud balls that hit my face DID sting a bit, but after a while I guess my face got a thick enough layer of mud that it didn't sting much anymore. The mud balls hitting my cock and balls always stung however!! Although I couldn't really see them, the guys apparently gradually moved in closer and closer, and eventually just stood around me trying to bury me in as much mud as possible. At some point it got hard for me to breath, but I was able to blow out hard enough through my mouth to keep a sufficient pathway open.

When they decided that I was sufficiently covered in mud, they went back to swimming and just left me lying there tied up for what seemed like an eternity, but maybe was only about 30 minutes. Eventually they untied me and I could go into the pond and try to clean all the mud off.

This was a MOST memorable experience for me!! We never repeated it, although I would not have been opposed to doing it again. I never SUGGESTED doing it again. Back then I felt that these things just needed to happen organically, and for sure I didn't want them to know that I secretly enjoyed it.
