Old movie with a pool scene

Hi! I’m looking for a movie, but I can only remember one scene - there is girl hiding in a pool or a bathtub, underwater, and another girl leans in and kinda breathes iar into her mouth… One of them or both may be asian, but I am not sure. I am positive it wasn’t porn, cause I’ve seen on TV come 20 years ago or more) I know it’s not much, but if you have any suggestions, please, help!
