Kendall Jenner and Devin Booker are full steam ahead as they try to make out on every stretch of sea in Italy ... and this time the PDA is going down off the Amalfi Coast.
The supermodel and the NBA star took their yacht to Positano to kick off the weekend, with Kendall showing off her curves in a skimpy black bikini to work on her tan.
Kendall made sure to avoid tan lines on her back, going topless as Devin kept a close eye on her as she lay face down.
