This was tacky and extremely vulgar and had absolutely no relevance except to extend the scenes. Could you not have done that by showing a more appropriate song played in the background with lots of flashbacks ? This what you normally do when you don't have any original ideas to extend scenes and we are quite used to it.
If you want to screen such garbage then I think you should stop making family serials and go into producing po*n because that is where this dance sequence (minus a few clothes) belonged!
