Chapter 1

Disclaimer: I own nothing but my share of air

"Are you sure?"
"Positive!"
"Where are we?"
"Shhh"
From afar, you could see nothing moving the the quiet second floor corridor of the famous school of witchcraft and wizardry-Hogwarts. But when you close in and open up your ears, you can hear tiny whisperings bouncing off the walls, not the loud whooping made by the peeves, but the silent whispers of a boy and a girl, actually, a Head Boy and Girl.
A red haired girl and a boy with jet black hair is walking side by side, both under the invisibility cloak, they stole through the castle silently, in search of nothing.
Lily opened the door to an empty classroom, stepped in it, and looked around.
"Maybe this will do..." Lily whispered silently,
"It'll have to," James replied and grabbed her by the waist, inclining his head to meet his lips with hers,

"BOO," Sirius jumped from his hiding place behind the teacher's desk and sprang upon James,
"Out of bed, tut tut tut," Sirius slowly shook his head while looking at both of them, "and head boy and girl too!"
"What are you doing here?" James accused,
"And not to mention is suck a...compromising position,"
At this, James and Lily both blushed scarlet and avoided each other's eyes. Sirius chuckled lightly and looked at both of them sternly,
"Just make sure to use protection," And he bolted out the door after this,
If possible, James and Lily grew even redder and James was seriously considering chasing after him when he felt a light tug at his sleeves,
"Don't," Lily said with a un-Lily like gleam in her eyes, "Let's both have the fun, but tomorrow,"
They returned to their "compromising" position but much to their surprise, Peeves came barging in,
"Ohhhh! Head boy and girl out of bed!" Peeves glowed in joy and started to sing a song rather too...inappropriate for readers of all ages.
James's left eye twitched, Lily's red face and red hair made her look like she's on fire, and they caught each other's eyes,
"One, two, three," They mouthed to each other and together they lunged out the door, deciding that they couldn't wait until tomorrow for Sirius to pay for this.

This didn't turn out as good as I hoped, tell me if you want me to continue, I originally wanted a series of James and Lily caught red handed but I don't know now.
