"We like to leave it up to the imagination," Burke, 27, told PEOPLE backstage after the performances, adding that she and Levy have no plans to kiss.
But unlike judge Carrie Ann Inaba, Levy, 31, and Burke don't worry about whether an actual lip-lock was too much for the dance.
"I don't know," they both said at the same time. "They can do whatever they want."
Added Burke with a laugh, "I kissed [Levy's] nose. Is that good enough?"
Meanwhile, Hough told PEOPLE that he normally agrees that passion should be implied in dance – rather than actually acted out – he has no regrets about Monday's routine, which landed the couple a second-place spot with a solid score of 27 points.
"There was a place in the music where there was such a big build, we thought we needed to do something fun," he says. "And since we didn't [actually kiss] during the rumba, we thought, 'Why don't we actually do it [for our salsa]?' "
Calling the dance "sexy," Hough goes on to say, "Tonight it was fun. Tonight it called for it."
