A dark hallway

You enter by yourself into a dimly lit hallway where a woman in a red dress greets you. She hands you a small earbud like the kind you see in spy movies, and you put it in your ear. The woman motions for you to move forward into another door.

You enter and the door closes behind you. It's a small room with a door on the opposite end. It's also poorly lit. You look around wondering what to do when you hear a voice in your ear.

"Good evening sir. How may I address you?" It's a female with a very strong British accent.

"Uh, John," you say.

"Great. Nice to meet you John. I presume this is your first time?"

"Yes."

"No worries. I'll be your guide for the evening. My name is Theresa. The earbud also transmits back to me and I can hear you even if you just whisper. Each guest here has one of these earbuds and they each have a personal guide just like me."

"Okay..."

"Once you enter the main part of this building, it will be pitch black and you won't be able to see. Rest assured, we have state of the art technology and cameras in there, and I'll be watching you the whole time, serving as your eyes."

What kind of party is this? You're starting to wonder if you should leave.

"So what do I do in there?" you ask.

"John, as you probably know, this is a sex party. Once you're inside, you can choose to engage in any sexual activity you want to as long as the other person or persons consent," Theresa says.

"Interesting. Go on..."

"Sure. If you would, please remove your clothes and mask and put them in the box to your right. They will be brought to you when you're ready to leave in a room similar to this."

You go ahead and remove your clothes, wondering if Theresa can see you right now. The box retracts into the wall when you're done and you wait for Theresa's instructions.

"Thank you, John. Please step forward." The door in front of you opens and you step walk in. It's completely dark and it takes a few steps for you to get used to it. The floor is lined with gym mats.

"Don't worry, I'll make sure you don't injure yourself or step on someone," Theresa says, as though she sensed your unease.

"Okay. What now?"

"There are multiple areas. A buffet, pool, lounge, and others. Since this is your first time, I suggest going to the lounge where I can find a suitable guest for you to copulate with."

"Sure, let's do that."
