A/N: Smut, and lots of it.

It takes her a second to realize what it is she's watching, but even after she does, Annie doesn't think to look away. His body is blurred by the frosted glass of the shower door, but there is no mistaking the pumping of his hand. She's never seen him do this before. Annie wishes the glass between them would disappear so she could catalogue the differences between how she touches him and she touches himself. It is so easy to imagine the water beating down against his neck and shoulders before tracing the contours of his chest and down towards…

Finnick moans, and Annie is torn away from her fantasy. Only then does she realize that he probably hasn't yet noticed her presence. He has his head turned away from her, allowing the water to hit his cheek, and with the noise of their beast of a shower all around him, it would have been more if surprising if he had heard her come in. The thought makes her sick to her stomach. She's no better than any of them. No, she's worse, because he trusts her, and all she does is go and betray him.

Annie wants nothing more than to take the coward's way out, slip away and pretend nothing ever happened, but that wouldn't be honest. "Finnick?"

Immediately, his hand drops to his side, and he swivels towards her so quickly that she's certain he's going to fall. He opens the shower door just enough to pop his head out. "Sorry about that. Give me just a sec to clean up, and I'll be right out." Though his tone is even, it's impossible to miss the flush that extends from his neck all the way up to his temples.

"You don't have to stop for me." This is her chance, she'd better grab it. "I-I'd like to watch, if it's okay." Did that sound too pushy? She doesn't want to pressure him into anything he isn't comfortable with. "Or I'll just wait for you to be done, if that's better."

He thinks it over for a moment before opening the shower door a bit further. "Come on, you're not going to be able to see much from over there."

She moves to lean against the vanity. He's right – the view is much better from this angle. Finnick only lightly strokes himself as he waits for her to get settled, and once he sees that she's ready, his motions become more pronounced. Annie wants to drink in the sight. The shower is still on, and the steam drifts out around his body, providing the perfect, misty backdrop. Finnick alternates between keeping his eyes locked on hers and closing his eyes and tilting his head back when something feels particularly good. She knows much of it is a show for her benefit – his motions are exaggerated from what they were before, and his reactions are more extreme than when they are together, but that only adds to the appeal. When she murmurs encouragement, Finnick grins out at her and speeds up, moaning and groaning along with the motion of his hand and hips. The desire she feels curling through her abdomen is delicious, and Annie considers hitching up her nightgown and fingering herself, but she decides against it. Any distraction from this show is a sin.

He's close. Finnick's given up on the performance now. His eyes are shut tight, and he bites down his lower lip during those last few powerful strokes. Annie can't help but lean in, holding her breath until… there. His jaw tenses as he orgasms, and it's so strange to see the expression she's so familiar with from so far away, but it leaves her entire body tingling.

Finnick takes a few shuddering breaths before he opens his eyes again to smile at her. "C'mon, Annie, don't be a stranger." Add a wink on the end, and she's melting.

It's two steps from where she was sitting to the shower, and after the first, Finnick grabs her wrist and pulls her in, nightgown and all. Immediately, her clothes are plastered against her skin, and Finnick wastes no time in pulling her up against him. Annie drags him down for a long, open-mouthed kiss. She enjoys the varying textures of skin she can feel under her fingers. Where the water hits him, it is soft and smooth, with just a bit more slip than she is used to, and goosebumps dot his arms and chest, where she blocks the stream. With a moan against her lips, Finnick begins his own explorations: cupping her bottom, trailing up her spine, pushing the curtain of hair away from her face. The combination of the steady stream of warm water pounding against her back and Finnick's lips and wandering hands is almost too much to handle. When they finally separate – not far from one another, their lips still only a whisper apart, she has reached the limits of her patience. "Finnick, no teasing."

"Not even a little bit?" His hand starts to creep up towards her breast, and she doesn't have the heart to swat it away.

"None. I need this now."

He's toying with her nipple now, and her attempt to frown up at him is spoiled by a moan he coaxes out of her. Damn this man. Finnick shakes his head. "You're no fun."

"Really? It seems like you're having a lot of fun right now." Good, she'd managed to sound curt. He deserves it.

He tugs the nightgown over her head and tosses the soggy fabric over the shower door. Annie hears the splat of the wet cloth hitting the ground, but now that they're kissing again and his hand is so close to where she wants it, she can't bring herself to care about the puddle they'll have to clean up later.

Her knees buckle when he finally brushes against her clit, and not for the first time, Annie wants to commend whoever it was that came up with non-slip shower mats. Finnick wraps an arm around her waist. "No falling down on me." She frowns up at him, but his smile is infectious. "Come on now." He turns her so that she faces the showerhead and her back is against his front. As soon as she's settled into the new position, he resumes his ministrations, this time rougher and faster against her clit. She wraps her arms around him from behind and relies on him to keep her upright because she can't be bothered to keep her legs straight when he's doing such clever things with his hand.

A part of Annie wants to make it last, but she was already so wired from watching Finnick earlier that she knows that's not a real possibility. His constant kisses against her temple and whispered encouragement aren't helping her last any longer. It takes only a brief few minutes for Finnick to turn her into a moaning mess, and even when she comes down from that high, she doesn't want it to end.

Her first sensible thought afterwards is how freezing cold it's gotten in here. How did she not notice that the water had turned icy?

Teamwork is her turning off the water while he grabs a towel from the rack to wrap around both of them. Annie kisses his chest as she snuggles close. Yes, she has a busy day ahead of her, and yes, she should have been ready to go twenty minutes ago, but there's no reason everything can't wait a few minutes more.

A/N: For Lucy [Estoma] on her birthday. Hope it's a great one!
