You Make It So Good I Don't Want to Leave (гет)

It's late at night on the Tuesday before the big Potions exam and Draco can't find his textbook. When the Head Boy goes to the Head Girl's door to ask if she's seen his book, he hears the most intoxicating sounds from behind her door.
“Oh yes, please. Yes, right there, Draco…”
Wait. Was he hallucinating? He must be.
“Fuck, yes, Draco, please…”
No, that was definitely his name that time. He looked down at himself, stupidly wondering if it was possible that he could actually be inside her room instead of, frustratingly, outside of it.

Classic Heads trope. Smutty goodness.
