Tongue


It's the summer after Derek and Casey's second year at Queens. It's August, and Lizzie, Edwin and a few of their friends are at the mall, Marti is at a friend's house and Nora and George are at work.

That's how Casey ended up here. She's sitting on the island countertop in the kitchen, her legs wrapped tightly around Derek's waist and her fingers threaded through his hair, her lips on his.

Casey slips one hand down from his hair, down his chest, coming to a rest over the bulge in the front of his jeans.

Derek groans, his fingers digging harder into Casey's lower back, pulling her closer against him.

"Maybe we should go upstairs," Casey whispers between kisses, her voice breathless.

Derek laughs lightly, smirking against her lips.

"We could," he replies, his voice low and gravelly. "Or, we could stay right here."

Derek unzips his step-sister's sweatshirt, guiding the fabric down and off, leaving it in a pile on the counter.

"Oh, come on, D," Casey laughs, palming him through his jeans. "Not in the kitchen. That's just unsanitary."

Derek laughs in return, his fingers inching up the fabric of Casey's t-shirt slowly. He's about to pull it off of her when the front door slams shut.

"Oh, gross," Edwin groans, dropping his backpack by the front door.

Derek and Casey pull apart, and she tries to hide where her hand had just been by fixing her shirt.

Casey bites her lip, uncrossing her legs from around her step-brother.

"Nah, definitely not gross," Derek laughs in response to his brother, stepping back from the counter, winking at Casey.

Lizzie snorts, rolling her eyes at her step-brother.

"I agree with Edwin. I could've gone my whole life without seeing your tongue rammed down my sister's throat," Lizzie hisses, her voice slightly sarcastic.

Derek shrugs, giving Casey a hand to help her down from the counter.

"It's not the worst place my tongue could've been when you walked in."

Casey's eyes widen and her mouth falls open in surprise.

"Der-ek!" she shrieks, not believing that he just said something so vulgar in front of their younger siblings.

Derek laughs, amusing himself thoroughly, reaching behind Casey to grab her sweatshirt from the counter and handing it to her.

"What? You're usually a very big fan of my tongue," Derek states, now just trying to get a rise out of his step-sister.

Derek and Casey have been technically in a relationship for over a year, closer to two if you count the first ten months. But Derek Venturi will never tire of causing Casey frustration. It's like a sport to him— like hockey, and he loves both.

Casey shakes her head, her cheeks pinking up as she crosses her arms over her chest.

Lizzie rolls her eyes and Edwin snorts to hide his laughter. Lizzie notices the exact moment Casey's demeanor changes. Lizzie knows her sister very well. And Casey knows Derek very well, ergo, she knows that sometimes, the best course of action is to stun him into silence. He doesn't always know when to shut up otherwise.

"That's true, D," Casey responds, sauntering slowly towards the stairs, her eyes locked with his. "So, why don't you put your money where your mouth is. Or, more appropriately, put your mouth where your mouth is."

Casey punctuates her statement by bolting up the stairs, not even bothering to see if Derek had followed her, knowing he'd be right on her tail once his mind registers what she said.

Lizzie could swear she hears Derek almost growl before he takes off after Casey, following her up the stairs.

"Well, I'm willing to bet we should stay down here for a while," Edwin laughs, elbowing his best friend lightly.

"I think you're right."


"And you say I'm a bad influence on the kids," Derek laughs, closing his bedroom door behind him, eyeing the brunette girl in his bed.

"I was just trying to keep you from saying anything else inappropriate in front of Lizzie and Edwin," Casey replies, lying down on her side in her step-brother's bed.

Derek's eyes rake over Casey's curves.

"Oh, please," Derek scoffs, crossing his arms over his chest. "They're sixteen. You can pretend all you want, but I know for a fact that Edwin isn't a virgin anymore. So, I don't think I'm corrupting anyone."

Casey's eyes widen. That was news to her.

"What? Did he tell you who?" Casey questions, admittedly a little shocked.

Edwin is a sweet kid and he's grown into a fine young man, but Casey definitely wasn't expecting to learn that he'd been following in his older brother's footsteps. At least, she hopes he's not.

"Nah," Derek answers, taking a seat beside Casey. "But he said she's really important to him. So, at least he's not doing half the girls in his grade."

Casey rolls her eyes.

"You mean like his brother?" Casey points out, playfully nudging his shoulder.

Derek laughs lightly, leaning down, over her, pushing her down onto her back.

"Like his brother used to."

Casey smiles up at him, leaning up and pressing her lips to his, suddenly remembering their earlier time in the kitchen and the effect Derek has on her body.

"But enough talking about Edwin's sex life," Derek laughs, leaning down and sucking gently into the skin of her neck. "I seem to remember someone telling me to put my mouth where my mouth is."

Casey's eyes flutter closed and her teeth dig into her bottom lip.

"And you said it yourself, you are a big fan of my tongue," Derek drawls, his voice dropping low as he kneels back, his hands immediately going for the waistband of Casey's leggings.

"Derek," Casey moans softly, lifting her hips to help him remove the leggings, which he shoves down to the end of the bed.

Derek smirks down at her, licking his lips before his head disappears down between her thighs.

Casey fists one hand into the sheets beside her and the other into her step-brother's hair, tugging hard on both.

"Oh, my—"

Casey's legs are locked over Derek's shoulders, and his fingernails are biting into her hips and his tongue— Derek was right. Casey is a very big fan of his tongue.


Hello, friends. SO. Funny story. I'm considering this one-shot as part of the "Red-Handed" series, however, there isn't really anything specific that points to this being in that series. Either way, this idea came to me and, well, here we are.

Thanks for reading, as always.
