All Lucius could see was red when he happened upon a rumpled Narcissa stumbling out of an empty classroom with an equally rumpled Slytherin fourth year.
He'd been doing his nightly, head boy rounds in the dungeons when he'd heard shuffling and giggling coming from a classroom that shouldn't have been occupied so late at night.
Hoping to give out some unnecessary detentions to some mindless first years, he'd walked towards the door, only to be almost flattened by Narcissa and the boy that was currently clinging to her.
Now, she stood in front of Lucius, her hair tousled in a way that he found far too attractive, and her shirt half unbuttoned and hanging loosely off of one shoulder.
Lucius' nostrils flared, eyes darkening and hands curling into fists.
"If you're not out of my sight within the next three seconds, you'll wish four months of detention with Filch was the worst I did to you," Lucius hissed at the boy, even as his eyes remained on Narcissa.
The boy's eyes widened comically and he dashed down the hall, disappearing around a corner before Lucius could even blink.
"You ruin all the fun, Lucius," Narcissa drawled, her lips pushing into a delicious pout that Lucius wanted to devour.
"Just what the fuck do you think you're doing?" Lucius demanded, ignoring his desires as one hand lashed out to hold Narcissa's wrist in a vice-like grip.
Narcissa's eyes flashed briefly, red hot anger whipping him—burning him—before it was gone just like that.
"I was only playing," she replied, exasperated, as if Lucius should have known.
Lucius glared at her, his eyes narrowing at the swelling in her lips that could only come from kissing—or other intimate acts.
"You're mine," he growled, yanking her arm so that her body was pressed flush against his.
Narcissa's breath hitched, her eyelids fluttering and cheeks tinting with arousal.
"I wasn't aware that I belonged to anyone, let alone you, Malfoy," she hissed, but her flustered state betrayed her, as did the playful glint in her eyes.
"Did last night," Lucius breathed against her neck, "not make it clear for you? Or, what about all the previous nights before?"
Lucius emphasized his point with his tongue, dragging it up the side of her neck and curling it around her earlobe to bring it into his mouth, biting down hard enough to leave a bruise.
The shudder that ran through Narcissa sent pleasure shooting to Lucius' groin, and he couldn't suppress the groan that crawled up his throat when he heard her whimper.
"You're mine, Narcissa," he repeated. "Stop acting like you aren't."
Narcissa leaned back, looking up at Lucius through her thick lashes in a far too innocent manner.
"Are you going to punish me, Lucius?" She simpered, her heart beat quickening so much so that Lucius could feel it through their shirts.
"I did quite enjoy the feel of Tony's—no—Tobias' hands running up and down my—"
"Mine," Lucius snarled, pulling her even closer as his grip tightened.
Narcissa would have bruises come morning.
"Don't tell me," she said breathily, slowly turning to back him into the recently vacated classroom, "show me."
A/N: Thanks so much for reading! It didn't take me too long to update, right? I know these first two chapters have been a bit short, but don't worry, not all of them will be! Reviews are always appreciated :-)
