Kourtney Kardashian Wore a Gucci G-String Bikini While Making Out with Travis Barker on a Boat

Kourtney Kardashian and Travis Barker's PDA tour around Italy is showing no signs of slowing down. After they were spotted making out over aperol spritzes, gelato, and lunch the other day, the couple seemingly kept the kisses going — this time, aboard a boat.

On Sunday, Kardashian shared a photo of the pair engaging in yet another steamy make-out session while touring Portofino by sea. In the picture, Kourtney is facing away from the camera, as she wraps her arms around Barker and leans in for a kiss. She wore nothing but a tiny black G-string bikini with a silver Gucci logo emblazoned on the back of her suit. Her hair was wet and left down in natural waves.

"That's Amore," Kourtney captioned the PDA-filled snapshot, to which Travis replied in the comments section with a black heart emoji.

Barker also posted his own snapshot of the couple sharing another smooch on the boat, coordinating in black hoodies and matching sunglasses. "Italy," he wrote alongside the sweet photo. Completing his sentence, Kardashian responded, "With you."

Their trip to Italy is the couple's second international vacation this month. They visited Cabo two weeks ago, and true to form, Kourtney and Travis documented nearly every moment of the romantic getaway on Instagram (PDA, included).
