I'd be breathing heavy, letting him know how 'good it feels' and just getting off knowing my penis is in another man's mouth. My orgasm, though, would be fairly loud. And I'd prefer no hands during oral. If you're good at giving head, you can get me off hands-free. Oh, one other thing, no leaking my cum. Take it in your mouth and swallow it, all of it. I'd do the same for you.
