Title: Whatever We Started

Disclaimer: This is a work of fanfiction using characters from the Atypical Universe. I do not own Casey or Izzie, they belong to each other.

Ratings/Warning: Casey and Izzie are both minors (16 or17 years old) consenting to a sexual relationship. Not recommended for people who have a problem with that or young kids.

Summary: "Yeah, I'm a bad boy." But what happened after the camera cut?

"Is that a tattoo?" Izzie asks, grabbing Casey's arm.

"Yeah, I'm a bad boy," Casey tells Izzie before Izzie straddles her girlfriend's lap, leaning down to kiss her as they fall back into the bed. Casey's hands move to Izzie's hips. Izzie grinds against her girlfriend, still kissing her.

Izzie adjusts her body so that she is just straddling one of Casey's legs. She moves her hips, rubbing herself against Casey's leg. Casey looks up at her, both have pure desire and love in their eyes. Casey grabs Izzie's shirt, trying to pull it off. Izzie sits up enough to help her pull it off, tossing it to the floor then moves to get Casey's off as well.

Casey bites her bottom lip, a little nervous but she's ready for this. Izzie nudges her back to lay down again before placing kisses on Casey's neck while cupping Casey's breast through her bra. Casey arches her hips against Izzie's.

"Someone's eager," Izzie giggles.

"Only because I love you," Casey says, being all serious. Not just saying it because they're about to have sex, but genuinely means it.

"And I love you, Casey. So much." Izzie pulls her hair to the side again, starts kissing Casey again, moving back down her neck and across her chest, along her bra line. She pulls back, Casey sits up a little, letting Izzie pull her sports bra off. Izzie pulls her own off, both winding up in the pile of clothes on the floor.

Izzie slowly makes her way down Casey's body, placing loving but hungry kisses down Casey's body further and further until she's at the top of Casey's jeans.

"Still have way too many clothes on," Izzie comments. Casey just nods, sitting up again, making quick work of her pants, tossing them to the floor, along with her underwear. "Much better," Izzie smiles as she's throwing her own pants in the pile, leaving her underwear on for now. She turns to look Casey right in the eyes.

"You still ready?" Casey just nods, she's never been so sure of anything in her life. Her first time (or even her second first time) with Evan didn't feel like this. She instinctively spreads her legs a little, giving Izzie full access to her. Izzie kisses her on the lips before sliding her hand down Casey's body, immediately finding Casey's arousal.

"Fuck, you are so wet," Izzie comments.

"Always for you," Casey whispers.

Izzie looks Casey in the eyes as she slowly pushes two fingers inside her. Casey's eyes flutter shut as she lets out a moan. Izzie takes her time, exploring and experimenting to see what her girlfriend likes. She spends a long time letting her fingers explore, never stopping kissing Casey. When Izzie knows that Casey is close to orgasm, she stops her hand and slowly slides down in the bed, kissing Casey's inner thigh.

Casey pushes herself up on her elbows, looks down at Izzie. "Iz?"

Izzie looks up at her, "shhh, I love you, enjoy yourself," she assures Casey before slowly using her tongue on Casey's clit. Izzie is in no rush, she wants Casey to enjoy this. A little awkward at first, but Izzie finally gets into it. Izzie spends a lot of time using her tongue and fingers discovering Casey's body and what illeticts the best reactions. Using the perfect combination of two fingers and a gentle sucking on her clit is enough to push Casey over to an intense orgasm.

Izzie moves to lay next to Casey, watching her come down. Casey finally opens her eyes and looks over at her girlfriend. She never felt like that after sex with Evan. "Just wow."

Izzie smiles then kisses her, "you are so sexy."

"Come here," Casey climbs on top of her, one of her legs between Izzie's. Izzie pushes her hips up, wanting some relief. She starts moving her hips against Casey's thigh, moaning as she does. Casey reaches down, her fingers finding Izzie's arousal. She looks back to Izzie's face.

"I'm ready," she assures her.

Casey slowly pushes one finger into Izzie, watching for her reactions. Izzie moves her hips to adjust. Casey then shows Izzie the same love, finding what works best on Izzie, varying between speeds and pressures until she is in that sweet spot. Almost immediately after finding that spot, Izzie has her first orgasm, taking Caesy by surprise that it happened that quick.

Izzie buries her face in her hands after she finishes, "that was embarrassing."

"No, it was totally adorable." Casey kisses her. "Don't you ever apologize for your needs being met." Casey kisses her again, starts moving her hand slowly again. Izzie bites her bottom lip, nodding, letting Casey know she's ready to keep going. The second time Casey brings her to orgasm that night was more intense than the first and Izzie is more than satisfied.

The girls are laying in bed, facing each other.

"That was definitely worth the wait," Casey says quietly.

"It was." Izzie moves closer, bringing her arm around Casey. "And I couldn't have asked for a better first time."

"Is it bad that I'm already looking forward to our second time?"

"I'm looking forward to a lot more sex with you. Whatever we have is beautiful." Izzie touches Casey's face before kissing her.

Casey slides out of bed, picking her clothes up off the floor.

"You going home?" Izzie sits up, pulling the blanket over her body.

"Not yet. I just don't want your mom to find me in here naked."

"She won't be home until at least tomorrow afternoon, if you want to stay."

"You sure?" Izzie nods."I'll text my mom to let her know."

Casey sits on the bed, next to Izzie after getting her phone from her jacket. She's messaging her mom back and forth when Izzie slides her naked body onto Casey's lap, straddling her hips.

"You up to go again?"

Casey tosses her phone to the side, "Yeah," she looks at her girlfriend, putting her hands on her hips. "Always ready for you."
