I had done it many times by guys around my age but the first time by an older gentleman was when I was about 19, back then I was maybe 120lbs dripping wet and about 6 feet tall, he was probably in his 40s maybe 50s.
I was in Laguna Beach on a somewhat deserted part of the beach laying out wearing a red g-string.
A guy approached me and asked if I needed lotion on my back, without looking at him I instinctively said yes.
He spent a lot of time on my legs and ass and even slipped in finger every now and then right up against my hole.
He Introduces himself and that's when I get a good look at him and he's wearing an almost similar g-string I was, he was so much bigger, it couldn't contain him and his balls were hanging out, he was ripped and very good looking man.
He says, lay there for a bit and when you're ready I'll lotion up your front side, so about 30 minutes later he comes back and says okay flip over, so I did and he took a very slow long time rubbing lotion on me and when he got to my cock and balls he just teased me. Now this suit barely fit me, so with a hard on I was definitely popping out of it.
About another half hour passes and he comes back and says would you like to come back to my place? I live in trailer park adjacent to the beach it's just a short walk. So being the exhibitionist I am, I put everything in my backpack and just walk over to his place wearing only my g-string. He was walking ahead of me and when I turned around and saw that I was only wearing my G so he also dropped his shorts and walk along me wearing his G.
Thinking about it at the time I really didn't know what was going to happen I just thought maybe he wanted look at me or watch me play with myself, he asked if I wanted to shower and get all the lotion off and I figured I'm done at the beach so yeah.
He's joins in about halfway and it's just gently caressing me and I figured I should do the same back.
When we're done he says let's go outside I have a private patio so we both walk out there totally nude and it is private with outdoor futon looking bed.
I sit on the edge of the bed then he pushes me fully onto the bed, now I'm laying down face down he dives his tongue into my ass and begins to eat my hole for what was probably a good 30 minutes while fingerings me, playing with my cock and balls. I get a little scared and I think he's going to fuck me I don't have a condom.
He's then rolls off and looks at me and says it's your turn now, now this guy was ripped and had a good 8incher with really big and low hangers. He takes charge of me and tells me what to do, how to do it, he asks if he could be rough and I said let's try it.
He begins with lights slaps witch increase in intensity and is forcing me down on his cock, holding my head and not let me come up. It got to a point when I was come up he would slap me across the face and push me back down almost every time.
He's says I need to take a break and put this on and he has me put on a pair of white stockings.
When I go back to sucking he now has me take my time and work it and lick it every way I can.
After he was so aggressive he then says tell me when it's okay to cum.
He shot his load and I someone swallowed all of it but not quite.
We both shower again had a really nice conversation, he asked if I would like to get together with him again and I agreed I saw him several more times.
