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."
