I’m 12 years old and I suck my stepbrother‘s cock he’s 16. He has a really big penis. I don’t even have hair on my cock. He’s got a nice pubic hair around his dick and it’s long and thick. Mine isn’t very big I guess cause I’m 12 years old. I hope it gets bigger. He’s twice the size of me longer and much bigger around I like the girth about four months ago. I had asked him if I could suck it. He said sure he didn’t hesitate.
