Science Doesn't Explain

Twelve: Casual Intimacy

A/N: Contrary to what's implied in the title, we here at Jay's desire to not humiliate themself decided not to write smut. Enjoy the chapter!

Lena adjusted her dress, her eyebrows stitched together as she studied herself in the mirror. Her hair, though in a messy ponytail, reached halfway down her back. She sighed as she managed to tug down the zipper. She returned to her closet and sifted through the clothes, sighing to herself. Her black dress? Too much cleavage. Her red one? Too short. Pink, too girly, blue didn't even belong in her closet. Her phone buzzed loudly, then began playing "Mine" by Taylor Swift, which was her ringtone for Kara. The blonde had set it the same day Lena had allowed her to put her fingerprint into Lena's phone.

"Dia duit, grá," Lena chimed, pressing the phone to her ear with her shoulder.

"Hey. Are you freaking yourself out yet?" Kara teased. Lena allowed a smile to find its place on her lips as she stared at the disaster that her room had become.

"Only a little." The brunette squeaked, obviously lying through her teeth.

"Okay, whatever you say." The wind whistled through Kara's end of the line.

"Are you talking and flying? I swear, Kara, I will send Alex after you." Lena insisted.

"Oh, what am I going to do, forget I'm flying?" Kara groaned, rolling her eyes.

"Land on my balcony, you idiot. I can see you from here." Lena laughed, hanging up the phone to open the sliding glass door to her balcony.

"Sorry. I was just listening to your heartbeat, and I wanted to call you, so I did, and.." Kara rambled on, then realized the mess before her. "Oh, Rao, you're a mess." Lena wore a halfway unzipped dress that barely covered her shoulders, and there was a mountain of clothes atop her bed.

"Help?" Lena murmured, her head tilted to the side as she smiled innocently.

"Where's that red one?" Kara sighed, beginning to sift through the pile. Lena picked a dress up off the ground, holding it out to Kara with a light blush spreading over her cheeks.

"This one's cute, and Eliza will not care what you wear, so put it on." Kara insisted. Lena sighed, turning and pulling her hair out of the way so that Kara could finish unzipping the dress she already had on, which the blonde did, without a second of hesitation. They helped each other get ready for events countless times before, so Kara was used to zipping and unzipping dresses for Lena. What she wasn't used to was Lena allowing the fabric to fall to the floor, revealing her bare back, shoulders, and oh Rao...Kara couldn't handle it. She turned her head to the side, trying to calm herself down as Lena turned around, chuckling at the sight of Kara's bright red cheeks.

"What, the ass is too much for the girl of steel?" Lena teased, cocking her head to one side.

"Lena, no," Kara muttered, her cheeks turning impossibly redder. The blonde shuddered as hands found their way to her hips, taking handfuls of her cape to pull her in. Lips were less than an inch away from her ear as Lena stood on her toes.

"What's wrong? Don't you like the view?" Lena's tone was low and sultry and her breath hot against Kara's skin. Kara wasn't used to this. She wasn't used to wanting this so much. After Krypton, and growing up on a planed where sex didn't even exist anymore, Kara had never wanted this. But Lena was pressed flush against her front, and Kara couldn't think about anything else. Kara closed her eyes, squirming under Lena's grip.

"Lee, no," Kara whimpered, pushing Lena away. Her cheeks were on fire, and her heart was racing.

"Are you okay?" Lena murmured, stepping back.

"Yes. No. I'm not sure." Kara mumbled, burying her face in her hands.

"We don't have to if you don't want to." Lena cupped Kara's cheeks, gently placing her forehead against the super's.

"It's not that I don't want it, I do, it's just...On Krypton, we weren't supposed to want sex, or have it. It wasn't...it wasn't how things worked." Kara explained quickly. It felt...awkward, explaining this element of her home planet. She'd never told Alex, because how was she supposed to bring that up? 'Hey, Alex, cool fact about me, my parents literally never had sex, and neither did anyone else on Krypton. I have intimacy issues!' And it wasn't exactly a conversation she'd liked to have with Kal.

"You don't have to explain if you don't want to, you know?" Lena asked, running her thumb over Kara's cheek.

Kara shook her head, pulling away, "Yeah, but I kind of want to. I mean, this is part of Krypton no one but knows about, and I think you'd find it fascinating. Well, scientist Lee will."

"You wanna sit down on the couch and let me put on clothes?" Kara nodded, placing a gentle kiss on Lena's forehead.

"You're my favorite."
