A/N: Hey all! I know it's been a while since chapter 1 of this but I've always known I had more in store for this fic. I know I'm toeing the line of what can safely be called a T rating, but I don't think it's quite to the point of needing the M rating. Also, I'm not sure how long this will be now that I've picked it up again but I know where it's going, so here goes! I hope you all enjoy chapter 2!
It all goes well for one month and then two. They're both experts at undercover, so keeping their life undercovers separate from their lives at work is relatively simple. They soon develop a pattern of staying the night at one apartment or the other and going their separate ways in the morning, pretending nothing's different at work, and no one's the wiser. Jay's starting to wonder why he ever worried about his and Erin's relationship affecting their jobs.
Two and a half months into their relationship, the catch a case that requires under cover work at a sex club. He leans against his desk, arms crossed across his chest as he watches as all of his coworkers' hands fly in the air to volunteer. His joins them eagerly. Who would he be to turn down that assignment?
Erin focuses in on her computer, clearly uninterested.
Voight scans the room before choosing. "It's gotta be a couple. Halstead and Lindsay."
Jay takes a long breath to keep his cool. Out of the corner of his eye, he sees Erin's grasp on her pen falter the slightest bit. Voight wasn't on to them was he?
Their unspoken question is answered a second later when their boss crosses the bullpen to stand immediately in front of them. "You two can handle this, right?"
"Yes, sir," Jay replies with a curt nod. "Whatever we have to do to come across convincingly in there, I'm prepared."
"So noble," Erin comments with a convincingly uninterested eye roll before turning to Voight. "We'll be fine, Hank."
He barely nods to acknowledge her, further encroaching on Halstead's space instead. "Just make damn sure you two only do what's required for your cover. I want every detail in your report when you return. Got it?"
He's trying to think of what to say to keep the sergeant off his back when Erin comes to his rescue. "He's my partner, Hank, not one of the boys I snuck out with as a teenager. You have nothing to worry about."
"Right," Jay seconds. "Only professionalism here, Sarge."
"We need to go change if we're going to get there in time to locate our suspect. Let's get out of here," she says, standing and heading for the exit.
Jay hastily turns to follow her.
"Every detail!" Voight calls after them, but neither of them acknowledge that they hear him.
"Did you see that? Did you see what's happening there?" Jay asks her as they pass a group of women taking turns sucking the cock of a man who was laid out on the bar.
"I thought you were excited to take this assignment," she teases, scanning the club for their suspect.
"Now that we're here, I'm kinda tripping out. I didn't think the sex would be quite so out in the open."
She laughs at him. "I'll do the talking."
They approach the bar and Erin gets the bartender's attention. Jay swallows his jealousy watching her. He knows she's acting, but that doesn't make it any easier, especially not when she invites the man to play with her. He chokes out an encouraging statement and follows them into a private room.
"Hey," Erin soothes, making her way over to him after Brad leaves the room.
He pulls her into his lap, immediately relishing her warmth against him.
She wraps herself around him, planting a kiss firmly on his lips.
"That was harder than it should have been," he admits. "I know it was all pretend but I don't like the idea of sharing you."
"I'm all yours now," she purrs.
"We have to report back to Voight."
"Not until we get some information… I doubt Brad will have that any time soon."
He moans at the feel of her lips against his ear.
"Please, Jay," she pleads, her voice barely above a whisper. "I want you to play with me."
He can't refuse her. He fuses his lips to hers, snaking his hands into her hair.
It's not long before their clothes land in a pile on the floor and he claims her as his.
The green monster quickly retreats as their moans and cries intermingle. Erin takes his mind off of the mission and he soon forgets he'd been jealous at all.
She holds him close even after they finish, peppering kisses around his face, neck, and shoulders. "I love you," she whispers over and over and over. "You're the only one for me." Normally, she might not be so sappy, but right now, she knows he needs the reassurance. She'll give it to him in any and every way he wants.
A few months later, Jay stares at the desk across from him, trying to be subtle about how much he's watching the stairs, waiting for Erin. She always cuts it close getting in to work on time, but this is late even by her standards.
Maybe she just got stuck in traffic.
When lunch time rolls around and Erin's still not there, he starts to get worried.
"Linds coming in today?" Atwater asks. "It's weird we haven't heard anything from her."
Jay shrugs. "I haven't seen her since work yesterday." It's the truth. Normally, he would have gone to her place or her to his, but she told him last night before leaving work that she just wanted a night alone. He missed her, but really couldn't blame her. They were spending nearly all of their time together.
"Sick day," Al says. "She texted Hank this morning. Says she hopes to be back tomorrow."
Jay nods and turns back to his computer. When he's sure no one is watching, he sneaks a text to Erin: "How are you feeling? Anything I can bring you after work?"
Her response comes a few minutes later: "Just you… or I can meet you at yours."
He texts back that he'll come to her. No need for her to drag herself around the city if she's not feeling well.
The rest of the day passes at a snail's pace. He can't wait to get to Erin.
He buys her daisies and chocolates on his way to her place. He knows it'll brighten her day.
He knocks on the door and is shocked when it swings open almost immediately.
She pulls him inside and wastes no time wrapping her arms around him. She presses him back against the door, kissing him hungrily.
He responds in kind, wrapping his arms around her as best he can with his hands full.
"I guess you're feeling better," he remarks when they finally break for air.
"Take me to bed," she commands.
He sets the daisies and the chocolates on the coffee table as they pass it on the way to the bedroom.
There, she takes control, quickly ridding both of them of their clothes. She pushes him onto her bed and takes him into her hand at a decidedly slower pace.
It takes a lot longer than usual before they're both worked into a frenzy, panting and grasping for every bit of each other they can get.
She cries her release, falling down on top of him. A couple more thrusts and he's right behind her, her name tumbling off of his lips.
He holds her close, not caring that he's still buried inside her.
"I love you," he whispers, stroking her hair gently. "You are so beautiful. I love you so so so much."
She says nothing in return but buries her face in the crook of his neck.
Jay repeats his soft praises, just relishing the feel of her against him. . . until he notices her shaking.
"Erin?" he asks quietly. "Er, are you okay?"
A sob escapes and she starts shaking harder.
"Hey, talk to me," he tries again.
There's still no response, just her sobs wracking through her body. She's really got him worried now. He holds her tightly against him, hoping that'll help somehow.
She nestles against him, her tears dropping onto his shoulder.
"I'm here, babe. I'm always here," he soothes. "I've got you."
He doesn't know if she's listening, but he doesn't know what's wrong. He just holds her. That's all he can do until she decides she wants to talk.
