>>2169079Some women use pole dancing as a means to exercise, while simultaneously learning how to dance seductively for their husbands/boyfriends. There's probably no lewd intentions from the girls themselves, this being DOA. But I can see it as a somewhat interesting activity they were (reluctantly) willing to try once.
That was in X2, of course, where it was made clear the casino was empty and they wouldn't have ever attempted it if there were other people present. In X3 (and VV eventually?), the implication is that it's a 'Private Dance' for Owner-san, and the sexual innuendo is far stronger.
