A/N: Because I can't get enough of Voight. :) AU set within season 5.
Adam Ruzek regretted going into the station that night. Looking back, he should have stayed home. His new girlfriend had encouraged him to curl up on the couch with her and he desperately wished he had.
Two hours earlier ...
Adam strolled into the empty bullpen and straight to his desk when he heard sounds coming from the sergeant's office. He looked up to see the door slightly ajar and spotted his fellow Intelligence Unit teammate Cali McDermott in Hank Voight's lap.
"That's odd" was his first fleeting thought followed by the horrifying realization thought of "Oh my god, she's riding him!"
Like witnessing a wreck on the highway, Adam couldn't force himself to look away. His mind was whirring as he questioned why the young detective would jeopardize her career by sleeping with the boss.
Adam heard Cali whine something to Hank, and he lifted her off only to spin her around to face the desk and re-enter her from behind. Cali's face contorted in pleasure as Hank pounded into her.
Slapping his hand over his eyes, Adam stealthily backed away from his desk and silently cursed. He would never unsee that, damn it.
He lifted his hand long enough to turn around to flee down the stairs, but not before locking eyes with Hank.
The next day Adam contemplated calling in sick. The thought of facing Hank was nearly making him ill anyway.
But he also knew Hank would know he was feigning it, so he took a deep breath and went to work anyway.
When he arrived at the station, the team was assembling as Hank barked orders.
"Ruzek, you're with me," Hank instructed as everyone dispersed.
Adam internally groaned but nodded, "Sure thing, boss."
Hank didn't say much other than what was related to the case until they were staked outside waiting for the target to show.
"Did you find what you were looking for last night?" Hank nonchalantly asked. Adam swallowed and uncomfortably shifted in his seat.
"Yes, sir," he choked out. A silence fell between them for a few minutes before Hank spoke again.
"I don't make it a habit of having sex at the office, but sometimes things won't wait until my wife can get home," he casually said.
Adam felt like he was having the birds and bees talk with his father again and cringed. It was definitely not a topic he wanted to discuss with his boss, especially Voight.
Then it suddenly dawned on him.
"You and Cali … married?" Adam stuttered in disbelief.
Hank merely grinned—which actually bothered Adam more than witnessing the sexcapade—before slipping back into his dark and scary cop mode as the target appeared on the scene.
Back at the bullpen Adam just sat in shock as he processed the news. How did he not know that Sarge was married to Cali?
He glanced at the detective in question who was perched on the edge of her partner's desk, laughing at something Jay had just said. He noticed for the first time that she had a slim wedding band on her ring finger.
Adam tried to remember if he'd seen Cali and Hank interacting or touching or being together at off-duty functions or at Molly's. He had known that Erin Lindsay and Cali had met in training and that Erin had recommended Cali as her replacement but …
"Something on your mind, kid?" Al Olinsky asked his partner, snapping Adam's attention to the present.
"Voight and McDermott?" Adam questioned.
Al nodded as he looked at his oldest friend standing in his office discussing matters with Desk Sergeant Trudy Platt.
"Two years and counting," Al replied. Antonio Dawson overheard them and slapped Adam on the shoulder. "It was a small beautiful wedding and Erin came back to Chicago to be Cali's maid of honor."
Adam's jaw dropped. "Am I the only one who didn't know they were a thing?"
Cali sighed and stretched as she slid off Hank before curling into his side, still breathless. Despite the fact he was older than her by 15 years, her husband's stamina rivaled men her own age.
Hank absently stroked the arm that rested on his chest and kissed the top of her head.
"We need to be more discreet at the office in the future," he gently recommended after they had lay in bed a while.
Cali lifted her head to look at him, puzzled.
"I thought we were. What brought that to mind?" she asked.
"Ruzek," Hank said as if that answered her question. She raised an eyebrow and patiently waited for him to elaborate.
"He accidentally saw us last night when he came in late to pick up a case file," Hank replied. Cali stared at him without blinking before a slight smile broke out.
"So what you're saying is you didn't get your door closed all the way?" she teasingly accused him.
"I'm saying you were awful needy, sweetheart, thus rendering me forgetful in my old age," he responded with a chuckle.
This time Cali outright laughed before playfully slapping him on the shoulder and resting against him again.
They were sound asleep when Hank's phone rang in the early morning hours. He growled before reaching for it. Cali rolled to her side away from him and burrowed deeper under the covers.
"Voight," he gruffly answered. When he heard the voice on the other end, he became more alert and sat up.
"What's wrong, kiddo?" Hank asked immediately concerned. Cali stirred next to him, rubbing the sleep from her eyes.
"Nothing's wrong," Erin's voice softly said. "Just wanted to hear a friendly voice. Sorry to call so early."
"You know you can call me anytime," Hank tenderly told his adopted daughter. They chatted about nothing for a minute before she asked to talk to Cali.
Cali extended her hand to take the phone. Hank handed it to her before crawling out of bed and heading for the bathroom. Cali waited for him to disappear before speaking.
"Ok, babe, spill. What's going on?" she said.
Erin shared how frustrated she was among other things to the point Cali offered to come visit. Erin waved her off, but her voice belied how she really felt.
By the time Hank returned, Cali gave him a look that told him they were going to New York.
After the third day of sightseeing and briefly popping into Manhattan to say hi to the Special Victim Unit, Hank and Cali had nearly convinced Erin to come back to Chicago with them.
"What would I even do? I can't return to District 21," Erin lamented with a sad smile.
"Roman's security company is looking for good people," Hank said. "That would keep you in the game without you having to cross paths with Internal Affairs."
Erin reached out to her old friend Kim Burgess to see whether Sean Roman would even be interested in taking her on. Kim immediately put her partner (and husband) on the phone and he wholeheartedly agreed without a second thought.
"When can you start?" Sean asked.
