Head closer to the stage

You make your way over to the stage where a large group is already standing. Itzy continues to rock out. You spot a small door near the stage that appears unguarded, you realize you could easily slipped in if you wanted and perhaps get a backstage look. On the other hand now that you are closer to the stage you notice this doesn't appear to be anything like a normal kpop concert. For one the clothing Itzy is wearing is much sluttier than normal. They are all wearing clothes with their boobs clearly on display. But that is not all. You notice, oddly enough, that the crowd isn't watching the sexy Itzy band dance and sing their hearts out. No, instead they are watching a couple fuck right in front of the stage. You have no idea who they are but you notice a couple of the guys already have their dicks out and look ready to join in.
