A/N. Ok, so obviously neither Don nor Adam are likely to visit an underground club, but for the purposes of this fic (and my own twisted imagination) I'm saying they would.
This fic does contain some mild BDSM/kinky content. If that bothers you, kindly leave the fic and don't yell at me for it. There will be some Danny/Mac in later chapters, and the M rating it just for good measure.

Adam took in a shaky breath and looked around. It was almost too dark to see, and the pounding music made him feel disoriented. It wasn't a good idea to be here. He should just go home; go to bed. He didn't know what had possessed him to come to this place. He was about to turn and leave when his path was blocked by a well built man. Adam smile politely and tried to sidestep the man, but he moved to stop the lab tech.

"Excuse me," Adam said quietly. When he didn't move, Adam assumed the man probably didn't hear him. The man smiled.

"Let me buy you a drink." Adam shook his head, becoming increasingly worried.

"I was just leaving."

"But you just got here," The man replied with a smirk. "I saw you come in."

"I'm sorry, but I have to go." The man grabbed Adam's arm when he tried to leave again.

"It's just one drink. It won't take long." Adam looked around, beginning to panic. He didn't know what to do to make this guy leave him alone. He turned back in time to see someone tap the man on the shoulder.

"Hey pal," A voice Adam vaguely remembered. The man turned from Adam to the person who had tapped him.

"Take a walk." As soon as he saw the man addressing him – all six-foot-something of him, Adam's arm was released.

"Hey, sorry," The man smiled apologetically. "I thought he was alone."

"Well he aint," Adam closed his eyes; trying to place the familiar voice in unfamiliar settings. When he opened them again, the man who'd been talking to him was gone and his arm was being taken by the other man. Looking up, Adam could just make out the features of the other man. Immediately he realised who it was.

"Flack?" Adam barely whispered, but apparently he was heard, as Flack's grip tightened on the younger man's arm.

Adam was led to a quiet back room. This room was lit better than the main floor, and Adam quickly registered the look of irritation on Flack's face. It was so close to anger that it almost made him flinch.

"What the fuck are you doing here?" The question was posed in a calm tone, and Adam got the distinct feeling this is how it felt to be interrogated by the detective.

"A-a friend of mine told me about it. I wasn't gonna come, but then I decided I may as well try, but now I wish I hadn't. What are you doing here?"

"What made you think coming here would be a good idea?" Adam sighed, knowing Flack was ignoring his question on purpose.

"I… Do we have to do this here?" Adam looked around worriedly. Flack sighed heavily. When Adam looked back, the detective could see the look of fear in the younger man's eyes.

"Ok, c'mon," Flack said softly, holding Adam's shoulder gently. "Let's get outta here." Adam smiled gratefully and followed along as Flack led him from the back room and out through the club.
