You Keep A-Knockin'

A/N: Kurt is intrigued by the new guy who has moved into his building. However, some odd comings and goings lead Kurt to believe that the new neighbor might be in a rather unsavory profession.

Kurt was never happier than when the residents of 5B moved out. They were rude, loud, and had the absolute worst sense of fashion (if Kurt had seen the guy in socks and sandals one more time…). He was curious as to who the new tenant would be. Rumor had it that the apartment had been leased to a single man, early to mid-20's, and rather cute, if Mrs. Moskowitz in 3F was to be believed. She'd mentioned the cute part last, and had given Kurt a wink, adding in her usual, unsubtle way that perhaps he could be Kurt's new special man. Bless her heart, at 82 she was always trying to set Kurt up with one guy or another. Sometimes they were even gay.

Kurt had no time for such thoughts. No. After a string of unusually horrible first dates, he'd imposed a dating hiatus. He didn't care how cute or eligible 5B was. Now was the time to focus on himself. He was doing well at Vogue. He had moved to this apartment near Midtown, happy to be closer to work than when he'd been rooming with Rachel in Bushwick. As of three weeks ago, he started writing his first novel, working in the evenings when his creativity was at its peak. Yes, now was Kurt Hummel's time, and woe betide any hot young bachelor in 5B who tried to get in his way.

Knock knock knock

Kurt almost jumped up at the sound until he realized that the knocking was being done on the door across the hall – the infamous 5B. He glanced at the clock and saw that it was nearly 11:00 p.m. He raised an eyebrow at the hour, thinking it was rather late for a visitor, then he shook it off and went back to his writing. It was none of his concern what 5B did, after all.

He had gotten a couple of quick glimpses at the man (whom he still called 5B in his head because they hadn't spoken and he didn't know his name). He didn't know if Mrs. Moskowitz was right about him being single, but he certainly was cute. He was a little shorter than Kurt, but a little broader, too, weth well-toned arms that were muscular but not in a bulky way. He had dark, curly hair and the most adorable triangular eyebrows. Kurt hadn't gotten a very good look at his eyes, but they appeared to be hazel - maybe just a little brighter than that. He dressed well, too – the last time Kurt saw him, he was wearing a well-fitted black polo and tight red pants that hugged his…

Kurt shook his head and cleared his throat. No, he did not have time to spend mooning over the hot guy across the hall (yes, he'd moved from cute to hot at some point). 5B was off limits.

Kurt heard the door across the hall open and a quiet greeting being exchanged before the door closed again. He had become accustomed to the thin walls of the building and usually didn't notice the sounds from the hallway, but perhaps his thoughts about the new resident made him more aware than usual. With a shrug, he went back to writing. He could get another hour in at least before he absolutely had to stop and get to bed.

Just as he was closing down his laptop, he heard the door across the hall open again. Hmm. Apparently, the late-night visitor wasn't staying. He glanced at the clock and saw that it was now 12:15 a.m. – time for him to make his way to bed if he wanted to get any sleep. So long as his new neighbor didn't make too much noise, he could have all the late-night visitors he wanted, as far as Kurt was concerned.

Okay, so maybe Kurt changed his tune a little over the next couple of weeks regarding 5B's visitors. The late visits weren't the exception, they were the rule. Almost every night it was the same thing. A couple of knocks, some very quiet chatter, and then the door opening and closing a little over an hour later. On a few occasions, there were two separate visitors in one night – one around 10:30, and another around midnight.

Not that Kurt was keeping track.

His dating embargo meant that he was home alone most nights, which he told himself was just as it should be so that he could work on his novel. He was actually making some progress on that, but he was also finding himself paying an inordinate amount of attention to the noises across the hall. One night, he happened to be near his door when he heard the inevitable knocking. Without thinking twice about it, he rushed to the door and peered out the little peephole which gave him a perfect view of the door directly across the hall. Just as he looked, the door opened and he saw 5B smiling as he greeted a petite Asian woman with a hug and a kiss on the cheek. "Hey there, handsome," the woman drawled, squeezing 5B's bicep that was gloriously on display in the tight t-shirt he was wearing. 5B smirked and laughed, then guided the woman into his apartment with a light touch to the small of her back.

Of course, Kurt thought. Well, he'd have to tell Mrs. Moskowitz she got at least one part of her information wrong. It looked like the cute/hot guy across the hall wasn't playing for his team, after all.

But wait a minute, Kurt thought as he wandered away from the door and over to the kitchen to get a cup of tea. What kind of guy has his girlfriend come over at this time of night for an hour?

Oh, ew.

Trying to put the neighbor's apparent booty call out of his mind, he went back to work on his book. This – this was why he wasn't dating anymore, he reminded himself with a disbelieving shake of his head.

He ignored the sound of the door across the hall opening a little over an hour later. He really tried to ignore it when he thought about the times over the past few weeks when he'd heard a second knock on the door. He seriously didn't want to think about that at all.

Knock knock knock

There was no logical reason why Kurt should go to look out the peephole when the knock happened the next night. No reason whatsoever. He had seen what he needed to see yesterday, so he had no expectation of seeing anything different.

Therefore, imagine his surprise when (a) he looked out the peephole anyway, and (b) he was greeted by the sight of a tall blonde man instead of the young lady from the night before. "Wasn't expecting that," he muttered to himself, sending up an apology to Mrs. Moskowitz who was apparently only half wrong.

The door opened, and 5B emerged, smiling once again. He and the blonde man hugged briefly and then entered the apartment. The door remained open for a few seconds as 5B spoke to his visitor about something, and then it closed. In those few seconds, Kurt could have sworn that it looked like the apartment was dimly lit with a bit of flickering light, such as would be thrown off by candles.

Well. It looked like 5B got around.

Finishing up his most recent chapter, Kurt rubbed his eyes and closed his laptop. He stretched a bit, then rose to make his way to bed. He groaned when he realized he hadn't taken the trash out after dinner. Those takeout containers were going to smell awful in the morning. With a sigh, he closed up the bag and walked to the door. With his hand on the doorknob, he froze.

He glanced at the clock – it was just after midnight. Crap. The last thing he wanted to do was to run into 5B and his blonde boy toy in the hall. He waited a moment, trying to decide what to do. He was exhausted, and really didn't want to wait around to see when the festivities across the hall would be over. "Screw it," he said, opening the door.

He stuck his head out first, looking warily up and down the hall. No one was in sight. He slipped out the door and practically ran down the hallway to the trash chute. He deposited the bag, making as little noise as possible, and hurried back towards his apartment. Just as he put the key in the lock, the door of 5B opened.

He rushed inside, but was unable to avoid hearing the conversation of the two men as he did so.

"Again, that was awesome, man," the tall blonde said. "I know I'm gonna feel that tomorrow, but it was soooo good," he went on. Kurt wanted to die.

"Well, you said not to go easy on you. I just gave you what you asked for," the resident of the apartment replied. Kurt was caught between being appalled by the discussion and being entranced by the dreamy voice of 5B. Kurt wasn't a prude by any means, but there was just something creepy about listening to that type of conversation. It made him feel like he needed to bathe.

For the first time in weeks, he missed the guy with the socks and sandals.

The following week, things escalated.

One of the girls at work had a birthday party. It was nice to get out of the house for a change. He even forgot about 5B, and his variety of visitors. Kurt had fallen into the inexcusable habit of looking out every time someone knocked (disappointed when it was just the pizza or Chinese food delivery guy). So far, he'd seen no fewer than seven different men and women go in and out of 5B's apartment. Clearly, this guy was some kind of sex god, because they were almost literally lining up at his door and coming back repeatedly. It was disturbing.

The party had been fun, and Kurt was happy as he entered his apartment building that night. He stepped into the elevator and pressed the button for his floor. Just as the doors began to slide closed, a hand slipped in, followed by a tall man. He was attractive, with green eyes and chestnut brown hair that was a little too "boy band" for Kurt's liking, but still stylish. The man gave Kurt a smirk then leaned over to press a button. "Oh," he said with surprise, "looks like we're going the same way."

Kurt gave a polite but disinterested smile. Between the second and third floors, a terrible thought hit him. He checked his watch – it was just after 11:00 p.m.

Oh, crap.

The doors opened on the fifth floor and the other man gestured for Kurt to exit first. With a quiet "thank you," Kurt stepped forward and turned towards his apartment. He ventured a glance back and saw the man was right behind him.

Yep. Looked like 5B's visitor of the night had arrived.

For some reason, the whole thing made Kurt nervous. He fumbled for his keys as elevator guy knocked. Kurt dropped his keys altogether, sighing as he picked them up.

"You know, maybe you should go see Blaine," a voice behind him said in a sly tone. Kurt turned around slowly to see the green eyes surveying him with amusement. "He could help you work out some of that tension," he added with a salacious wink.

Kurt's mouth dropped open in shock. Before he could reply, 5B answered the door.

"Hey, Sebastian," the man said, hugging his visitor in his usual fashion. "Come on in."

"Hey, Killer. I was trying to drum up some new business for you," he said, jerking his head in Kurt's direction as Kurt stood there gaping with his keys in his hand. 5B, or, as Kurt had just learned, Blaine, looked past Sebastian at Kurt.

"Hi," he said, almost shyly, Kurt thought. When Kurt didn't respond, "Come on, Bas. Leave him alone or I'll count this as part of your time," he said, taking Sebastian by the arm and pulling him into the apartment. He gave one last seemingly apologetic smile to Kurt before turning to close the door.

"No way. I'm not paying for you to make heart eyes at the guy across the hall," Kurt heard Sebastian say just before the door shut with a quiet click.

Kurt remained motionless at his own door for a moment longer, then rushed to get inside. He walked over to the couch and practically fell down onto it. He stared at nothing in particular in front of him in the dimly-lit apartment, processing all that he had heard over the past few moments. Putting the pieces together and coming to what seemed to be the only logical conclusion, his heart began to pound. He pulled out his cell phone and dashed off a text message to his former roommate, Rachel, praying she was still awake. He needed to tell someone. Now.

To Rachel: I think the guy in 5B is a prostitute.

A/N: Uh oh! Is Blaine really a prostitute working out of the apartment across from Kurt's? Or has Kurt come to the wrong conclusion altogether? Stay tuned to find out! (The story will be three chapters, so you won't have to wait too long!)
