The Slytherin common room was unusually quiet, with only the crackling fire and the soft rustle of pages turning from the scattered students filling the silence. Y/N lounged on the armrest of a couch, her legs stretched out in front of her as she casually read through a book, though her mind wasn't fully on the pages. Her attention kept drifting back to Theo, who had made himself comfortable and fallen asleep on the couch near the fire.

Y/N smirked to herself. Theo had a habit of falling into deep, peaceful naps at the most inopportune times, and today, it was a perfect opportunity to pull off one of her favorite pranks. She had been waiting for this exact moment. Theo, completely unaware of her intentions, was sprawled out on his back with his arms behind his head, snoring softly.

With the boys distracted by their own conversations—Mattheo and Enzo quietly talking about a recent Quidditch match, Draco and Blaise in the corner discussing some new potions—Y/N knew she had just enough time to carry out her plan. She had picked up something from Hogsmeade recently: Inferno Plump, a lip plumper that promised to give a tingling, fuller look to lips but came with an intense, burning sensation. She'd tested it once and knew it was the perfect choice for her prank.

Her fingers slid into her bag, pulling out the small tube with a mischievous glint in her eyes. The rest of the boys were so absorbed in their own conversations that they didn't even notice her creeping over to Theo's side. She leaned down close to him, her breath soft as she carefully applied the lip plumper to his lips, coating them generously with the sticky gel. She grinned at her work, making sure to avoid making any noise as she tiptoed back to her seat, pretending to be completely engrossed in her book.

Not even a minute later, Theo's eyes fluttered open, and he let out a groggy groan as he wiped his face. He slowly sat up, blinking rapidly, then froze, his hand immediately flying to his lips. His eyes widened in alarm, and his voice was thick with confusion.

"What the hell?" Theo muttered, rubbing his lips as if something was wrong.

Mattheo glanced up from his conversation. "What's wrong with you?" he asked, raising an eyebrow.

Theo's hands were frantically running over his lips, his confusion growing into full-blown panic. "My lips!" he exclaimed. "They're burning! What the hell did I—"

Enzo tilted his head, eyeing Theo curiously as the redness on his lips became more apparent. "Theo, what's going on? Why do your lips look... bigger?" he asked, raising an eyebrow, clearly puzzled.

Theo didn't answer right away. He stared at his reflection in the mirror from across the room, and his panic grew. "They're burning! Seriously, what the hell is going on?" He continued to rub at his lips, hoping to relieve the painful sensation, but it didn't help. If anything, it made it worse. He looked back at his friends, his face flushed, now visibly irritated. "I don't know what happened! It's like someone set my lips on fire!"

Blaise chuckled, clearly finding this situation a bit amusing, but he was still trying to figure out what exactly was happening. "You look like you kissed a dragon, Theo. What did you do?"

"No, seriously, this is burning!" Theo's voice was now a little more frantic, his hand clutching his lips in a futile attempt to stop the intense heat. "It feels like they're on fire!"

Draco took a few steps toward him, inspecting Theo's lips with a suspicious look. "Theo, mate, you're looking a bit... fuller than usual," he noted, his tone laced with disbelief. "Did you eat something strange? Or is it a potion gone wrong?"

"I swear to Merlin, I haven't eaten anything strange! It's like my lips are about to explode!" Theo nearly shouted, turning to Y/N, who was still pretending to read, hiding a smirk behind her book. "Y/N! Did you do this?"

Y/N looked up innocently, her face the perfect picture of calm. "What? I didn't do anything, Theo. I'm just reading." She could barely keep a straight face, but she was determined to maintain her cover. Her gaze flickered quickly over to the other boys, who were looking from Theo to her with growing suspicion.

"I'm telling you, something's wrong," Theo continued, practically panicking now. "What the hell is happening to me? It feels like my lips are on fire! This is not normal!"

Enzo eyed him more closely, stepping forward as he analyzed the situation. "Theo... wait a second." He squinted. "Your lips... they look bigger, like really full. Oh my god," he gasped, his eyes widening in realization. "Y/N, did you use lip plumper on Theo?"

Y/N's eyes widened in mock surprise, though she was practically bursting with laughter inside. "Lip plumper? Me? I have no idea what you're talking about," she said sweetly, feigning innocence, even though her smirk was impossible to hide now.

"You did it, didn't you?" Enzo shot her a knowing look, and the rest of the boys were starting to catch on. "Y/N, did you put lip plumper on him while he was sleeping?"

Y/N bit her lip to keep from laughing outright. "I have no idea what you're talking about, Enzo. Theo just looks... extra today, I guess."

Theo's face was a mix of disbelief and frustration. "This is insane! I'm going to look like a freak if this doesn't stop! I swear to Merlin, if my lips don't stop burning, I'm going to—"

"Okay, okay," Mattheo interjected, his face the perfect picture of calmness, though there was a slight grin playing at the corner of his lips. He crossed his arms and looked at Y/N. "You've had your fun, Y/N. Admit it."

Y/N finally let out a soft giggle, her shoulders shaking with laughter as she put the book down. "Alright, fine. You got me. It's Inferno Plump. It's a lip plumper," she admitted with a mischievous smile. "I couldn't resist."

The boys all stared at her for a moment, Theo now staring at his lips in horror as the sensation continued to build. Enzo burst out laughing, shaking his head. "You're evil, Y/N," he said, still chuckling. "Theo, I'm sorry, mate, but this is all on you for napping in the middle of the common room."

Theo just groaned, flopping onto the couch dramatically. "I'm never taking another nap here again. I swear, next time I fall asleep, I'm locking the door."

Y/N, finally satisfied with the chaos she had caused, just shrugged innocently. "Lesson learned, Theo. Never sleep near me again."

The boys continued to laugh, with Mattheo giving Theo a sympathetic pat on the shoulder. "You'll be alright, mate. Just don't expect any sympathy from me. You're looking... extra today."

Theo shot him a glare, but even he couldn't suppress a reluctant smile.
