I've recorded literally thousands of blowjobs over the years so when I call this chick a "Hoover Mouth" I don't use the term lightly. I'm sure part of the guy's soul leaves his body and goes with his load as she's sucking out every last drop. The last guy she blew today pretty much summed it up with his parting words.
What makes her technique so effective is the constant suction and once she starts working on a dick, she doesn't stop until the guy taps out. She wants to be a blowjob instructor but until that becomes a recognized profession, she'll just have to settle with servicing strangers at blowjob parties and at the local video arcade.
