I remember catching live sex show in NYC just before the tight asses shut it down. Still some in Spain and Netherlands. But, I miss the days were the couples walked though the audience to get to the stage to perform. You were close enough to smell the sex.
I've been looking for scenes like this: live sex show with guys in the booths jacking off. Hot stuff. I found a couple from Europe, but the guys are just passively watching, not actively yanking their dicks. This takes me back to the good old days of porn theatres and adult bookstores, dropping a few bucks and watching my favorite pornstars fuck and suck--and leaving a mess on the TV screen and floor. Such fun!
I was not in the market to enjoy that but it reminds me swinger clubs that don't have financial transactions except the entrance fee or extras like private rooms
