"Skinny dip. What's that?" he asked.
"It means swimming." I answered. "Naked"
"Naked?" he looked worried.
"Well, you can keep your undies on if you prefer, but I'm going to swim naked" I said while I got 2 big towels for us.
As soon as I had grabbed the towel, I opened the door, hang the towels on the door handle and asked "Are you coming?"
Then I walked to the lake. It was only 100 feet away and before I had taken 10 steps, Ras came running up to me laughing.
"Are you really going to swim naked?" he asked.
"Yes, I told you didn't I?"
"Yes, but usually it's only the kids swimming naked. I've never seen a grown up do it".
"Well, if you want it to stay that way, maybe you should close your eyes, because I sure am going to"
"Nah, it's ok. I don't mind" he laughed.
When we got to lake we found a big rock, quickly stripped off and threw our clothes on the rock. I tried not to make a fuzz about the naked thing, in the hope that Ras would then feel comfortable enough to go naked too. It really is much more pleasurable to swim naked.
He hesitated a bit taking his clothes off. Maybe he was nervous or wasn't sure if he should strip naked or not. Or maybe he was just uncomfortable with me looking at him, so I tried not to. I'd get my chances to look at him later in the water.
I quickly took off my tights like it was the most natural thing in the world (which it aught to be), turned around and ran out in the water, yelling "last in the water is a rotten egg!"
Ras protested "Hey, that's not fair I wasn't ready!"
"I know. Rotten eggs are so slow!"
I jumped in and under the water right away, without looking back at him. Giving him some privacy to decide what to do. Then I swam out and enjoyed the feeling of the cool perfect water on my naked body.
After half a minute, I looked back and swam towards the bank. Ras was in the water to his waist, and as hard as I tried I simply couldn't see whether or not he was still wearing his underwear.
When I reached him, he started splashing water at me. I dove under the water, and swam up to him, grabbed him and tossed up in the air, making sure he landed on his feet and butt. I was delighted to see his cute naked butt in the air. He was so perfect in every way. I also caught a glimpse of his dick, but only very briefly. I was sure I'd get the chance to see more of it while we played in the water.
Ras yelled and laughed as he splashed into the water. Then he too swam under the water to attack me. The little boy was actually a very good swimmer.
When he reached me, he grabbed my legs, obviously trying to trip me, to get me under the water as revenge. I fought it a little before I let him push me over, so I fell on my back. When I came up again we were both laughing.
"You swim well, Ras" I said. "You swim a lot in this lake?"
"Yes, in the summer I swim a lot with my friend."
"Great. Wanna race me?" I actually thought he had a chance to beat me.
"Sure" Ras said.
We stayed in the lake for almost an hour, before we got tired. I was a tiny bit faster than Ras, but he could keep his pace for longer than me. But most of the time, we were just talking or grabbing each other, fighting or splashing water on each other. He loved it when I picked him up and threw him high in the air, to make a big splash. And I loved it too, as it gave me a great view to his naked body and lovely dick. He was so beautiful, I sometimes started to get hard. But I kept it under control, and I don't think he noticed it, those few times I briefly had a semi-erection.
When we got out of the water, it was no longer awkward to be nude and Ras didn't seem to hesitate or try to hide. I walked past our clothes and went for the towels on the campers door handle.
"Hey, what about our clothes?" asked Ras.
"Yeah, we'll get them when we're dry. I don't want to get them all wet" I replied.
"Ok" Ras said and joined me walking back to the camper.
I thoroughly dried off my hair, then quickly my body and feet.
"You want some hot chocolate?" I asked.
"Sure" Ras said with a big smile.
"Just be sure to dry your feet before you enter" I said as I walked naked into the camper. I hoped Ras also was going to stay naked.
I tossed my towel on a chair and went in the kitchen department and prepared some hot water.
Ras entered the camper too.
