It's a special excitement to fuck a bottom who's cock is bigger than mine ... it's as if I'm animating his cock and it becomes an extension of mine ... it's a great fantasy-come-true, especially if I can make him cum hands-free!
I'm from the Before Times when people didn't self-sort into tops and bottoms. I love a guy/enby with a big dick and I love doing all kinds of things with him/them. Skinny is nice because then his/their dick looks even bigger.
