I did a similar thing in Vegas but I've always felt guilty for it.

I was at a club with four other women and two guys, and we ended up being approached later in the night by a man who asked us if we wanted to go to a VIP table. We joined him and his friends and were all having a great time. Free booze, plenty of space. The guy with the table was hitting on my friend pretty hardcore, but he seemed fine so we all left her alone. Well, when it comes time for us to leave, the man grabs my friend's hand and we all file out of the club to go back to our hotel rooms. VIP Guy joins us. We walk out into the light of the casino and all the women notice it at the same time -- VIP Guy is covered in cocaine, all over his nose, clothes, and mouth. His eyes are bloodshot and he's got stains all down his shirt. I look down and he's got blood caked on his hands (seriously) and his fly is unzipped. He pulls out his wallet and I see him pull out a bag of pills, which he tries to discretely shove back into his pocket. I make eye contact with my friend who had been talking to him in the dark all night, and she's clearly losing her shit. This cat was shady, shady, shaddddyy.

During the walk back to the casino, I watch my friend struggle to say something. It's clear we need to ditch this guy, but she's not saying anything, and the two guys we were with were keeping quiet -- in retrospect, out of intimidation. This was not someone you wanted to mess with, and we began to realize just how high and fucked up he was as we were walking.

By the time we got to the hotel room, he was getting aggressive -- with my friend, with the guys. And yet no one said anything; it almost felt like we had gotten in too deep. I was getting nervous, and so was my friend, but no one stepped up. When we sat down on the couch to smoke and unwind, VIP was groping my friend and whispering in her ear. I didn't know what else to do, so I yelled, "Let's play truth or dare!" I thought I'd get shut down, but the game started, and after a few actions, it got to me.

"VIP Guy!" I said, with faux enthusiasm. He turned his attention away from my friend for the first time, looked at me, and my whole body was on edge. Please, I thought, Pick Dare.

And he did. And I faked thinking for a moment before saying, "Go out into the hallway and drop your pants." He looked at me, said, "Oh, so you want to see what I got, baby?" and I nodded eagerly. He stood up, walked to the door, and I followed. He walks into the hallway, pulls his pants down, and I see his peen wagging in the breeze right before I slam and lock the door.

I turned back around and all of my friends are staring, open-mouthed, at me. They started to slow clap. I still feel guilty to this day. He might have been a good guy, I don't know. He might have had fine intentions and was just having a good time. But my gut was telling me otherwise, and my friend was more than relieved that someone had handled it.
