Cousins Large Dick

As a kid, I baby sat my cousin from time to time. Puberty was hitting me pretty hard and I constantly I was horny. Up to that age 13, I never thought about gay stuff or was attracted to guys at all. I watched nothing but straight porn. I forget exactly what got us in this situation. I think maybe a water balloon fight or water guns. But we both were soaked and we went inside to get dry clothes. I had none with me cause I was at my aunts. I took my shorts and underwear off and put them in the dryer for a bit. I did find a dry shirt, and I wrapped the bottom half of myself and I went to change my cousin. He comes running out in just a shirt. He found a clean shirt, but still needed underwear. But when he came out half naked something caught my eye... his dick, and how big it was for his age, even limp (his dad was black so.. lol) I remember I got instantly turned on and honestly, I didn't like it but I couldn't deny how horny I was.

Needless to say I told him that I'll find him some more dry clothes in a sec, I wanted to play COD. As I played I tried to think of a safe way to get him hard because I just had to see that thing of his at the biggest. This is what I did. Went to bathroom, got myself hard, put the towel back on me, walked like 2 feet from him and "accidentally" dropped the towel. His eyes went straight to my hard dick... he asked what was wrong with it and thought it was broke. (To that point in his life I don't think he had seen a man's dick) he couldn't stop staring. Then I took a chance and asked him if he wanted to wrestle around. He liked that idea (innocently) I remember picking him up and flipping him over. Kind of like a standing 69. With his head way down by my stomach, he couldn't see me sucking his dick... as soon as I put it in my mouth he giggled big time! I remember getting soooo turned on at the time. Sucking him maybe lasted 5ish seconds but I put him down and he asked "why did I tickle his wiener?" I just responded like "oh, it just got in the way and rubbed on my shoulder." He instantly dropped it. I finished by having him bend over the edge of the could so I can put one more wrestling move on you. I remember quickly licking his butthole (at 13, that was my biggest fantasy was to lick a girls asshole. Crazily, it was the most erotic point in my life at the time... I only had my tongue in his butt for about 5 sec and I finished by sort of dry humping his bare butt. I remember how good it felt. Just picture a hotdog in a bun. That's what we did that day, and about another 10xs at least that summer. I kept it simple and had him thinking we were doing something else. Like wrestling, etc. He is fully gay now and I'm bisexual.
