In the past when this question has been asked; a typical TUSCLer response has been “hey I only have one dick”.
Having said this; I’ve only tried double-dances and it wasn’t worth it – kinda hard/awkward to be able to equally enjoy both dancers simultaneously – what I have done several-times in the past is get back-to-back dances where I’ll get a dance w/ a dancer while the other sits next to us, then as soon as the song ends the girls switch; depending on the song-price and dance-quality I’ve done a set of 4 to 6 dances in a row (2 or 3 with each), on rare-occasion more songs – I once did this round-robin-method in a black-club w/ a set or 4 different ebonies.
That I can recall I’ve never done double-VIP – for one I’m not a big-extras-guy although I did extras from time-to-time when I was SCing – but what has probably been the biggest reason is probably the much-higher expense/investment – I’m also not that big on the ”girl on girl thing”; it’s not a turn-off but not something I necessarily crave. It's also often the case, though not always, that one of the dancers is not at the same-level of performance/expertise as the other one.
As others have said; if it's something that intrigues a PL, then experience it and see if it's-for-you/worth-it or not.
