It was a lazy Sunday afternoon in the Gryffindor common room, with most students off enjoying the rare sunshine on the grounds. You, however, had other plans. Sitting cross-legged on the couch, you rummaged through your bag and pulled out a tube of lipstick in your favorite bold shade. Sirius, lounging beside you with his head tilted back and arms draped casually along the couch, raised an eyebrow.

“What’s this then?” He asked, a teasing smirk playing on his lips.

You twisted the lipstick open and leaned forward, carefully applying it to your lips. Sirius watched you, his grey eyes alight with curiosity and mischief.

“Planning on making me swoon with those lips, darling?” He drawled, tilting his head toward you. You capped the lipstick and grinned nodding.

Without warning, you leaned in and planted a firm kiss on his cheek, leaving a bright lipstick mark behind. Sirius blinked in surprise, his smirk widening into a full grin.

“Oh, so that’s how it is?” He chuckled, but before he could say anything else, you kissed him again—this time on the other cheek.

“Hold still.” You said playfully, cupping his face to keep him in place as you pressed kiss after kiss across his cheeks, his forehead, and even the tip of his nose. Sirius, always one to enjoy attention, laughed softly, completely surrendering to your antics.

“You’re going to ruin my reputation, you know.” He teased, though his voice betrayed nothing but amusement.

Not satisfied with just his face, you tilted his collar open and kissed along the curve of his jawline, leaving smudged lipstick marks down to his collarbones. Sirius shivered under your touch, his laughter fading into something softer, more intimate.

“Careful, love...” He murmured, his voice low and teasing. “You’re making it hard for me to focus.”
