I was in Colorado with my younger cousin, I intended to go skiing with him and my uncle. We would go skiiing for the day, then come back and get into the hot tub that was outside my uncles house.
That day in the hot tub, me and my cousin went into the hot tub while my uncle was getting something from inside. He turned round to me and said that I should try sticking my penis in the things that shot out pressure, because it feels good. I looked at him, and he already had his cock whipped out and in the hole.
So I turned round to the one behind my back, and I stuck my penis in. I started to hump it, having done this before. My uncle then walked in to the hot tub, and saw what we were doing. He didn't say a word, but then did the same thing that we were. My cousin started moaning first, and then started to talk about how good that felt. I looked behind me and saw that his bathing suit was still off. I looked at my uncle, and we smiled at each other. Then I came, and my uncle came next.
Then my cousin said he wanted to do it again, and so he put it into the hole. Then I stopped him, and said that I would do it to him instead. He looked at me funny, and I reached over and wrapped my hand around his cock. He moaned once, then shut up. While I was jacking my cousin off, my uncle reached under me and started to pump my cock up and down. My cousin and I came at the same time, and it was great. My cousin and I looked at each other, smiled, and reached for my uncle at the same time.
He gasped, and I grabbed his shaft while my cousin took his balls. He massaged them while I jacked off my uncle. He moaned really loud when he came, and we just sat there, holding each others cocks in hand. We had many more experiences like this, and I might share them later.
