Supposedly, my current ATF's mother dances with ATF once in a while, but I've never caught mom there. ATF has said her mom used to be a dancer and other dancers have mentioned the idea of ATF's mother dancing with ATF, not to mention some freaky shit they apparently do together. At the least, all I'll say is mom probably dances with daughter occasionally, but anything above that I refuse to speculate.
I have experienced a mom and daughter together in the same club, though not in a threesome, of course. I liked mom much more than daughter, who seemed entirely mechanical. However, on a different visit to this exact club, I found out that mom was a bartender (naturally, an ex-dancer) and daughter was a dancer and mom was teaching daughter how to pole dance. The good news is she didn't have to teach daughter how to do a lap dance.
