Justin & Selena -- The Maui Make-Out Sessions

Teen lovers Justin Bieber and Selena Gomez didn't let jet skiing or parasailing get in the way of theirvery public displays of face sucking in Hawaii this week.

Justin got frisky grabbing Selena's ass and kissing her every chance he got while on vacation in Maui.

They've come a long way since their first public peck at the Billboard Music Awards just this past Sunday.
