Taylor Swift and Travis Kelce got hot and heavy in the Bahamas last week -- making out in the water while they were stripped down to their bathing suits ... and it's a familiar sight.
The couple got into the ocean Thursday while enjoying Harbour Island -- and they were ready to make out and get cozy on their vacation ... 'cause that's exactly what they did, not just among the waves but on the actual beach as well.
Take a look at the hot pics for yourself -- Taylor was all over Travis while he held her as they took a dip .
