Wow! What a difficult question. Not sure I could choose. I like different parts for different reasons. I love the horny feeling I get when a guy opens his pants and I’m staring at a nice bulge in a pair of shorts

It sets my mind racing, teases me.. I’ve not quite got what I want yet, but it’s close.. I like to rub it a little, denying myself for a little longer..
Then there’s the moment when he finally takes it out, wow ! Especially if it’s a nice cock. I love to lay eyes on it, it’s like I’m already sucking it with my eyes before I even put in in my mouth
Finally getting my mouth on it, yes. If I’m lucky enough to get it semi flaccid, then I can feel it harden to full in my mouth, that’s always a good feeling.. slowly at first, but then speeding up as I go. If it’s big enough, I like to wank it and suck it at the same time. Feeling the rock hard shaft in my hand while sucking and licking the tasty tip.
Then there’s the excitement when you can just tell it’s about to blow.. the pulsating feeling just as he’s about to cum.. I love the overwhelming feeling of a good load filling my mouth as I try to swallow it all, struggling to keep up with it as his cock is already filling my mouth up. Starting to feel the drips trying to escape out of the side of my mouth.. I’ll get those in a moment..
Then the feeling of accomplishment when I’ve swallowed it all, a proud moment

So.. to answer to this question, I don’t actually have a favourite moment.. I love it all
