Ask him to get you a drink

"Yeah, you can help me... where can a girl get a drink around here?"

You see him smile, and he says, "Wait here... I'll be right back."

You watch him walk away, admiring his firm ass. Your view is interrupted when a couple behind you bumps into you hard. You turn, and you see that they are oblivious to what is going on. The guy has his face buried in the girl's shoulder, and they each have one hand in the front of the other's pants. You aren't sure if they are trying to dance, or if their bodies are moving that way because of how turned on they're getting each other.

A quick look around tells you that they're not the only ones hooking up. Up and down the hall, you see couples -- and an occasional threesome -- pairing off from the crowd, openly making out. One amorous couple breaks off their session to head downstairs, just as another cry of "Show us your tits!" emerges from down below.

Soon your new friend returns with a large plastic cup of beer and hands it to you. You thank him, go to take a drink, and are again jostled by the horny couple behind you. You spill a little of the beer on yourself and a fair amount on the floor.

Your friend leans in and says, "It's pretty wild down here... Wanna go upstairs where it's not quite a crowded?"
