AN: Today, I stumbled across the 30 Lemons community on LiveJournal. This is going to be a series of one-shots featuring Scorpius Malfoy and Rose Weasley. Prompt 4 - The thrill of the forbidden, or "no, you must not!... Here, let me help you."

I don't own the characters, I just play with them.

They stumbled, giggling wildly, through a doorway. Clutching each other and pulling frantically at clothes, they knew just how close they'd come to jumping each other in front of the prefects. That wouldn't have looked good at all - the sensible Ravenclaw Head Boy and Girl acting like a pair of hormonal teenagers. But hormonal teenagers was exactly what Scorpius Malfoy and Rose Weasley were. Instructed by their parents at the beginning of first year to compete with each other and become lifelong enemies, they'd become firm friends instead. It was rare that the inhabitants of Hogwarts saw one of them without the other - they were very nearly inseparable. In sixth year, friendship had turned into something more, though they hadn't yet worked up the courage to declare it publicly. Word would undoubtedly get back to their parents, who would certainly disapprove.

The room they'd ended up in was little bigger than a broom closet, but that didn't matter. It was almost time for their next lesson, Potions, but right now the classroom in the dungeons was the last thing on their minds. Scorpius slid one hand under Rose's skirt, practised fingers removing her knickers. The scrap of fabric slipped down to her ankles, where she stepped out of them. An insistent stroking made her breath catch in her throat as she struggled to undo Scorpius's belt.

"We shouldn't be doing this, Scorp. Not here, not now." The words were right, but the breathless, lust-filled voice held no conviction.

"You're right, Rosie. We're going to be in so much trouble... here, let me help you with that." Scorpius unfastened his belt and trousers easily, then used Rose's thick hair to muffle a moan as her fingers closed tightly around his cock. "Harder, Rosie. Harder."

Rose had always found it a turn on when Scorpius gave her instructions, and his husky voice combined with his fingers between her legs pushed her over the edge. Scorpius watched her face, listened to the soft noises she made, and it didn't take long before he followed her into ecstasy.

Licking his fingers clean, he grinned wickedly at Rose. "Just you wait, Rose Weasley. I'm going to make you scream, I'm going to give you a night you'll never forget."

Rose smirked, a very Malfoy-like expression. "I'm looking forward to it."

They were very late indeed to Potions. They walked in together, only to be asked, "What in Merlin's name has kept you, Mr Malfoy and Miss Weasley?"

Rose and Scorpius glanced at each other, then back at the teacher. "Heads' business, sir," they chorused innocently.

Technically, of course, it wasn't a lie. They'd been occupied with matters involving the Head Girl and Boy, but not matters that they wanted to share.
