A/N: Thanks to all the people who take the time to review and favourite! I love you, you guys are the best. I have been posting so much smut lately, but it's not on purpose, pure coincidence there.

I hope you don't mind!

Prompt #9: Surveillance van. She always considered surveillance boring. Until he joined the unit.

Word count: 1,546

"Nothing is happening," she whines after hour four of their surveillance. They've already gone through most of the snacks, and they're not even half-way through the night. He suppresses a chuckle, earning a glare from Erin.

"It's night, people sleep at night. What did Voight think was gonna happen at night?" She is in a foul mood. Surveillance is tedious on its own, but surveillance at night, when nothing is happening, feels like a special part of hell.

"Actually, I'm pretty sure this is some sort of punishment for me," he replies, apologizing. She smirks. She knew it.

"Fine, then you be punished! But why me?"

"Maybe it'll pick up," says with hope and shrugs.

She scoffs in reply, fuming. Unlikely. But it does.

Minutes later the screen picture changes, and Natalie Stevens−the woman they're watching−gets a text, and then a visit.

"Well, that's not her husband." She remarks, and Jay laughs, but he has to admit she is right. The tall man who just walked into the bedroom is, without a doubt, not Natalie's husband. They put his face through the face recognition software and they listen with care, but the two lovebirds skip most of the talking, and get right to action.

"Oh, just great. Lovely," she mutters under her breath. She's sure she can see a slight blush on his cheeks, and for some reason she finds that attractive. He even looks away from the camera for a moment.

"She's not even into it. And his seduction technique could use some improvement. The guy has never heard of foreplay." He doesn't answer that. He's not sure his voice would work, even if he knew what to say.

"I'll bet you drinks at Molly's that she fakes it." She might as well get something out of this situation.

"Why would she fake it?"

"Uh, because he's not even trying?"

"Have you faked one?" That earns him a pause after which she replies with honesty.

"A few."

There is a brief moment, when all they hear is the sound of lovemaking, and he decides that talking about sex with his partner, is still less weird than watching that in silence. She smirks when he opens his mouth.

"I bet you wouldn't have to fake it with me." He intends that sentence to sound teasing, but it comes out wrong. So wrong. Maybe he's mistaken, but he thinks her voice is lower when she replies. Huskier.

"Would you be better than he is?"

"Wouldn't you like to know."

She swallows hard, her fingers finding a way to the back of her neck. It's just because it's a small space, she tells herself, and because he's too close, and they're talking about sex, and she hasn't had any in too damn long, but in that moment, Erin would very much like to know.

She takes her lower lip between her teeth to stop her thoughts from going into the direction they're going, but it's too late. She can imagine his strong arms on her all too well. And despite her earlier comment, she doesn't believe he's ever left a woman unsatisfied.

There is a beep on the scanner, and she's grateful for the interruption.

"Anything yet?"

They both jump a little at hearing Voight. She fills him in, and tries to ignore all the signs of arousal her body is sending her. It's going to be a long night, until she can go home and finally take a cold shower.

"Well she faked it, so drinks are on you," she teases when the noises stop. Now all she has to do is get the image of Jay out of her head.

"Here we are," he teases. "Back at it again."

"Good ol' surveillance," she yawns. "At night. Again. What did you do this time?"

"Maybe we'll get some action again," he says, cocking his eyebrow at her and promptly ignoring her question. A blush spreads across her cheeks. How did that happen? When did they switch roles, and she turned into a blushing idiot?

"Same bet?" She asks to recover.

"You're on."

A moment passes and she can see there is something bothering him, so she rolls her eyes, but asks anyway. "What?"

"Did you ever fake it?"

At first, she's not sure what exactly he's asking her, but then she sees the slightly unsure look in his eyes, masked with a cocky smile. It's hard to believe he even has to ask.

"What do you think?" He shrugs non-committedly, and she can't help but smile.

"I never had to." For a second they forget where they are, and there is only the two of them, while their eyes meet in a flash of sparks. His hand moves, brushing over hers casually, like it wasn't even intended, but he knows it was. They both do.

They get interrupted by the development on the surveillance camera. Coincidentally, Jay was right about the action. It's going to be another interesting night.

Erin still remembers that night in the van: the tension, the sparks, and the heat that spread over her body. She remembers how hard it was to breathe and swallow, and how long it took her to get the image of his body on top of hers out of her head. She remembers slipping her fingers between her legs that night after she got home, thinking of him.

But this is even worse. Because she knows now. She knows with perfect clarity how his body feels on hers, how skilled his tongue is, and how good he can make her feel. And the 'good' is so good, it dries her mouth in an instant. He looks at her, and she wonders if he can feel how much she wants him.

Of course, he can. He always can.

The woman on the video starts whimpering and begging for something, and Erin knows the feeling. Before she realizes it, Jay is next to her, his eyes piercing hers.

"Change of bet." She looks at him, wondering what bet he's referring to, because her mind is starting to get hazy, and she can't think straight. Then it dawns on her.

"I bet I can make you come before he makes her."

She breathes in sharply. If he keeps saying things to her in that deep voice, he won't even have to do anything, because she's already halfway there. She's about to say something about the professionalism, but he slides her a little forward, and her strong will evaporates.

"Don't forget to keep your eyes on the monitor," he orders, and she shoots him a look, but lets him slide his hands under her sweater, caressing the warm skin underneath. She's dressed in comfortable clothes, since she knew she'd have to spend the night in the van.

She shivers when Jay's slightly cold hands touch her skin. He leaves a trace of gentle kisses from the line of her jaw down to her neck. His teeth scrape the point where her pulse is, while his hand slips between her legs, rubbing her over the fabric.

She could stop him. She knows he would stop if she told him to, but her skin is already tingling with anticipation. She turns her gaze to the screen, seeing that nothing has changed, and allows herself to let out a suppressed moan.

He smirks at that, pressing harder against the fabric with his fingers. He knows he has her right where he wants her.

Her hips raise up to meet his hand, and he's aware he is not going to win the bet this way. He pulls at her leggings until they are low enough for him to slip his hand under. She moans at the touch.

His skilled fingers find her and start stroking. It's slow at first, then faster with every second that goes by. She pants against him with an aching need.

"Come for me, babe," he coaxes her. His voice is gentle−the complete opposite to his uncompromising fingers bringing her closer with every movement.

He captures her lips in a kiss, and it stifles the sob she lets out when she comes undone in his arms. She surrenders to him with reckless abandon, and he can't believe he ever doubted that her pleasure was genuine. You can't fake that.

He thinks of the time he asked her if she ever faked an orgasm, and she replied with "a few". Now, he feels sorry for the men who didn't know to bring her to this. Who didn't know how to touch her marvellous body, and instead only focused on their own pleasure. They never got to see the look in her eyes when she climaxes, or the strangled sound she makes when she's close.

His eyes flicker to the screen.

"I win," he murmurs, after seeing they still haven't finished, and she smiles. She feels so high, she doesn't even care that she's feeding his ego.

He loves the lazy smile that finds its way onto her face, and the dreamy look she gets right after. He loves that he's the only one who gets to see her like this.

"I think I win," she replies. And she did.

She won him.

And the best part is: that was just the foreplay.
