Disclaimer: I, very sadly, own nothing.

Thunder roars, the rain hitting the glass windows as the door creaks open, Jason making a mental note to inform Alfred about oiling the hinges as he steps into the library of the manor. He kicks the door shut with his foot, jamming his fists into the pockets of his jeans before he stutters forward.

He peers from the corner of a book case, a smirk lifting the ends of his lips. "How's the report coming?"

Blue eyes move upwards, meeting deep green ones and Jason frowns because dark circles are present beneath the blonde's eyes. Kate, however, cracks a tired grin, shuffling a bit on the tiled floor to make space for him.

"Just six more chapters and we're good." She informs as he crouches down beside her, carefully avoiding the history books scattered around them.

A scowl graces his features as he notices the pages lying at her side, "I told you not to do my part of work."

"Yeah, so we get a low grade again," She rolls her eyes, then stifles a yawn. "And anyway, I don't mind doing your work too. I mean, it's hard being a superhero when you've got school work to complete."

Jason glares at the books, "But you're tiring yourself out by staying up late." He grumbles, and Kate pinches the bridge of her nose, sighing.

"I'm totally okay working for both of us."

He attempts to argue, "Yeah, bu—"

She quickly cuts him off, folding her legs beneath herself. "Where's Mr. Wayne?" She inquires, looking around cautiously.

Jason rolls his green eyes, swaying his hand in the air. "The Joker broke out of Arkham today," He tells, grimacing. "Bruce and Dick are kinda busy tracking him down." He looks at her amusingly as she digs the heel of her palms into her eyes in a weak attempt to get rid of the sleepiness.

"So they're not here, right?"

Jason scoffs, "Yeah! I'm not stupid to make you come at the manor when Bruce or dickface are here." A grin tugs his lips then, and he cocks his head to the side, kneeling infront of her.

Kate arches a blonde brow, confused as he flashes a smug smirk. "You're not scared of the big 'ol Batman, are you, Rapunzel?" He inquires, humor in his voice.

Blue eyes narrow angrily at him, "I'm not afraid of Batman, Jason." Kate scowls, glaring and not catching that playful smirk on his face. "And I'm especially not afraid of a guy who dresses up as a freaky winged mouse in the nigh—"

But she pauses instantly, blinking with surprise because he cups her face and before she knows it, he's kissing her. For some reason, his mouth is a bit rough and it's hard to keep up with his sudden movements so she grips his shoulders, pulling him down.

Jason grins against her lips as she wraps her arms around his neck while his move downwards to her waist.

"Stop being such a tease, boy wonder." She growls, irritated, nails biting into his shoulders.

The tips of his ears burn a little red on hearing her call him that, and he responds by sliding his tongue over her mouth. She lets out a small squeak as he leans forward, pressing more into her and suddenly, her back is flat against the cool, pale library tiles, causing goosebumps to scatter over her skin.

"So now you're gonna call me boy wonder, huh?" He inquires, cheeks warm as he shifts back slightly.

He's answered with a heady noise as she pulls her lips away from him to catch her breath before Kate offers a cocky smirk, "I can totally go for bird brain or wonder bread if you want," She suggests, fingers digging into his black locks and pulling him back.

She tilts her head, tongue stroking his bottom lip but he trails kisses down from her lips to her neck, propping an elbow on the floor so he can balance himself as his teeth nip at the soft skin of her collar bone.

"I know I made a promise to you, Rapunzel." His voice is almost muffled, unclear and making her thoughts swirl crazily. "But I might leave a hickey—"

Kate quickly shushes him, "Less talking," she tugs at his hair, breathless. "more kissing."

Jason releases a small laugh, "If Alfred catches us, I am so getting grounded for patrol."

Her hold tightens more onto him, and to his surprise, she locks her leg over his to make sure he won't get off.

"You're not doing this 'cause you're sleepy, are you?" He sighs, frowning as he leans back a bit.

But soft fingers grasp his jaw, guiding his face back to hers. "You're more than welcome to stay at my house, Robin." Kate offers, fisting the back of his shirt and he almost falls on top of her.

He lets her press his mouth against hers roughly a few times, her tongue invading his mouth, leaving him breathless, until she's satisfied and exhausted, her tight hold loosening on him. The boy wonder pulls away, sitting upright to offer her an amused smile.

"You seriously need to sleep,"

"You're such a mood killer," Kate blows out a gust of air, blowing at the locks falling on her eyes.

An arm slides behind her back, helping her to sit and she doesn't bother to pull at the hem of her shirt that's riding up a little on her stomach. But she blinks, gasping with surprise when another arm is beneath her knees. Suddenly, she's up from the ground and Jason's carrying her towards the door.

"Where are we going?" She questions as soon as they are out of the library.

The sound of the rain outside becomes audible to her and she begins again, "What about the history report?"

"Why do you ask so many questions?" Jason asks sarcastically, quickly jogging up the stairs.

He bites back a smile when Kate clings onto him, as if afraid he's going to drop her down. Kicking a door open, he enters the room, surprising the blonde as he drops her onto the bed, crossing his arms and settling her with a stern glare.

"Sleep," He orders, then turns around to leave.

But a hand shoots out, clasping around his wrist, pulling him back and he loses his balance, planting face first into the mattress. His teeth grit together in anger, a scowl framing his features and just as he's going to spew out some curses that he needs to complete that damn report and how sleep is necessary, Kate clutches onto him arm, burying her face beneath his chin.

"Stay," she mumbles softly.

The anger melts somewhere inside him as he releases a heavy, deep sigh, shifting onto his side over the mattress, shoes still on his feet. He drapes an arm over her, patting her back.

There's a beat of silence, then: "You're not gonna leave me, right?" Kate murmurs sleepily.

A smile slipping on his lips, Jason drops his chin on her head. "No, Kate." He assures as she snuggles closer.

"I'm never going to leave you."
