Puncture, then suck.
It's really easy if it's a jugular vein...because all the blood spurts out by itself....
Don't ask how I know

Depends on the kind of vampire. Nosferatu suck through their teeth, the "classic" Romanian/West European vampire bites and then licks or sucks the wounds. And those are just the two more famous types.

I don't know if this matters or not but I posted this 2 weeks ago, just so you know

"Dracula no bite and suck, he scrapes and licks"

Vampire don't suck, vampire scrape and lick

I wanna kno too xD
