I Will Run You Like A Thread (Fem!Stiles x Derek)

Don't you ever tame your demons (but always keep 'em on a leash)

Stiles had expected things to be different in some way after Derek finally claimed her, like really claimed her, because it would have been ridiculously naive of her not to expect that. She's a human, sure, but her werewolf fiance decidedly wasn't, and with the insane amount of unknown alpha-magicky power flowing through his veins, the bite he'd given her surely had to mean something. But of course, it's not like she got any cool powers or anything, no. Instead, she was just really, really, really horny. Like a ridiculous level of horny, even for her, which was saying something. Which on the one hand, awesome, on the other -- incredibly, torturously inconvenient. Like right now when she's at her desk outside her father's office, curling her toes in her shoes and drumming her fingernails tap-tap-tap against the hardwood and trying not to remember exactly what Derek was doing to her only a few hours prior.

"Why is this happening to me?" Stiles gasps, clinging to the strong pair of arms trying to hold her squirming form in place against the mattress. "Am I in fucking heat or something? Am I dying? Are you dying? Are we both dying?"

Derek groans, rolling his hips in a way that makes Stiles's entire body shake because it rubs his cock right up against her clit, but it's just not enough, and somehow makes her want to die and scream and sing his praises all at the same time. Bastard. "You're not dying," he murmurs against her throat (since he'd bitten her last night, he'd barely been able to pull away from her neck for more than a few minutes), "and you're not in heat, because that's not a thing for us, Stiles. You're a human, not a wild animal."

"Not technically," Stiles murmurs, Derek chuffing a wry laugh against her lips before silencing her with his tongue, thrusting it into her mouth in a dirty, bruising kiss.

"It's just part of the bonding. I can feel it -- can feel you," Derek says, pulling away with a gasp before licking intently at her pulse point like it's a totally and completely normal thing for him to do. Like he's analyzing the taste of her or something as if he's some kind of werewolf supercomputer and he's calculating the best way to get her off.

"Didn't Joshua warn you this would happen?"

"Didn't Astrid?" Derek asks, eyebrow raised pointedly.

Which, okay fair she might've walked right into that one, but still. Surely they would've thought to tell her that it'd feel like her entire being was on fire and Derek was somehow the only one that could put it out.

"Besides," Derek adds, bucking his hips again until the head of his cock just barely teases its way inside her, dragging a particularly sharp whine out of her throat along with it, "I think not telling us might have been their fucked up idea of a wedding present."

"So this is some kind of fucked up werewolf idea of a joke? We have to bang until we pass out from dehydration?" Stiles gasps, digging her nails hard enough into Derek's back that she's pretty sure she might be drawing blood for real. "Because I'm not laughing. I'm dying, seriously. I think I'm really going to die if you don't hurry up and fuck me."

"And here I thought you couldn't get any needier," Derek snorts, grinding against her in a way that is absolutely driving her crazy because it's not enough. He's right there, teasing her, but she's pinned underneath him, helpless.

"Well," Stiles snaps, "you were wrong." As if she needs to illustrate her point, she sinks her teeth into Derek's shoulder because she knows exactly how that affects him, and she's not above using that weakness to get what she wants right now. Not when not having him feels like it physically hurts.

Derek snarls, and thank god that seems to do it, because he's suddenly ruthless now, thrusting into her until he's buried to the hilt where he belongs. Stiles locks her legs around him as if that could even keep him there, but she can try, goddamnit. She can try.
