Properly done....1- Get right to it. 2-Make no mess (Leave no residue behind. Most men I have to suck are married and they don't want their wives to find dried cum on their clothes.) This is the most difficult aspect for me because I always choke and gag on cum. All cum most be swallowed. Any leftovers to be lapped up and eaten. This is how I am trained and is the proper duty of a fag.
