Author's Note: This story is based off a 30 NSFW Challenge on tumblr, which you can check out on my blog, at pumpkinlessidjit dot tumblr dot com. Also, this is shamelessly named after The Killers song of the same name because I've had it on repeat for days and it seems vaguely relevant. Unless you listen to the lyrics, then you might get a little sad.

Also this is genderswap. I don't know if I need to specify, but it is definitely fem!Dean and fem!Cas.

They're in the middle of a diner.

Really, that's about all Castiel can focus on, that and Deanna's hand creeping slowly up her thigh. It's all she's been able to think about since Deanna pushed Castiel down into a chair at a square table in the back and scooted as close to her as she could.

This won't be the first time Castiel has gotten off with other people so close around her, and she's already getting wet anticipating it.

Deanna's hand inches higher as a waitress takes their orders, swinging around with her pony tail waving behind her to place the order. Deanna teases the inside of Castiel's thigh while she does something on her phone.

"You wearin' panties today, Cas?" she murmurs, drawl dipping deeper into her Southern accent than she usually lets show, just because she knows it makes Castiel squirm in pleasure.

"No." Well, not anymore, Castiel thinks, shifting at the sudden discomfort of not wearing underwear.

Deanna takes a slow sip of her water, eyes heavy on Castiel as her lips turn into a little smirk. "You're kind of a slut, huh, baby?"

Castiel whimpers as Deanna's fingers finally make it up to her cunt, still too light and teasing to provide any actual stimulation. She hates to imagine the mess she's making of her skirt and her chair, considering how slick she is.

"Can you spread your legs for me?" Deanna asks. "Show me how much you like this."

The long table cloth hides her thighs parting farther as Castiel slouches slightly in her seat. The vinyl sticks unpleasantly to the backs of her thighs as her skirt rides up. Castiel stares at Deanna, waiting. There's something like amusement in her eyes, surrounded by and drenched in arousal.

Deanna breathes, "Good girl," and then the tips of her fingers are brushing through slick wetness, slipping up to rub at Castiel's clit. Castiel bites her lip, eyes falling to the table as her breath rushes out in a huff. "Fuck, sweetheart. You really want this, huh?"

Castiel closes her eyes and nods jerkily, stomach muscles contracting. She flexes her toes—anything for an outlet. She's always been expressive in bed, loud and responsive and Deanna fucking loves it, but she loves it more when Castiel has to be quiet, has to force herself to keep her noises in and her movements stilled. Later, she'll probably push Castiel to her knees and tell her to get to work between Deanna's legs.

Castiel has to hunch in over herself at the wave of arousal that accompanies the thought.

"What're you thinking about, baby?"

"You," Castiel gasps. She doesn't want to say anything—has to catch herself on the beginning of a moan now that her mouth is open—but Deanna will stop touching her if she refuses to answer. Castiel understands the rules of this game.

Deanna hmms in acknowledgement, pressing the tip of one finger inside Castiel. Castiel curls her hands on the edge of the table, eyes squeezed shut and a moan trapped in her throat. It gets better, Deanna casually opening her up with two fingers in the middle of a restaurant,

Already, it's almost too much as Deanna crooks her fingers up, drags them right over that spot and makes Cas' head snap up as she inhales sharply.

"Think that guy over there suspects something, Cas?" Deanna asks. "He keeps lookin' over here, probably sees the way your face is red and thinks somethin' funny's happening. What do you think about that:? Someone else seeing what a slut you are that you have to get off with all these people around."

"He's not—" Castiel protests weakly, because she's staring the man in the eyes right now, and he looks positively smug as he watches.

Castiel's orgasm hits her just as the man winks and the heel of Deanna's hand grinds into her clit. Desperately, Castiel bites into her fists and ducks her head down, entire body shaking for what feels like forever.

Deanna pulls her fingers out slowly while Castiel catches her breath, unable to look up in case she catches that man looking at her.

"You did so good, sweetheart," Deanna says proudly. "My good baby girl, keepin' quiet like that, hmm?"

"Yes," Castiel pants, eyes flicking up to look at Deanna. Her pupils are huge, face flushed, and she grins wickedly at Castiel.

"Got one more thing I wanna do," she says, and she turns her head very deliberately to the man watching them. Castiel can't help but follow her gaze, but his eyes are fixed on Deanna as she slides two wet fingers in her mouth to clean them off. Groaning pathetically, Castiel can't look away either, staring as Deanna's tongue peeks out between her fingers.

The waitress turns up then, two giant burgers tucked into baskets for them, and Castiel can't help but stare hungrily at hers as she reflects on the fact that it's a bit of a miracle that no one else saw them.

"And Cas?" Dean says quietly. "I don't want you to mojo your panties back on for the rest of dinner." She winks lavishiously at Castiel and gives the man one more sly glance from the corner of her vision.

Castiel blinks in alarm, even as she feels her body wanting eagerly. This is going to be an interesting night.
