I own nothing but the plot

So I should work on my crossover, my one-shot series, or my reunion fic, but this plot struck my brain like a bolt of lighting! I know it's short, like really short, I'm sorry.

Minerva McGonagall was a difficult woman to shock. Nothing got to her. She was fully confident that she could cope with walking in on anything- after all, she did teach a bunch of teenage witches and wizards for a living. She had walked into every classroom in the school and seen students doing everything from shagging to dueling.

And that room that dissappeared.

That was weird.

But it didn't shock her.

The one time Minerva McGonagall was truly shocked was an incident that happened to occur one Halloween which involved two 'eighth years'(students who had returned to redo the year they had missed during the war). Two she had never expected to be involved in this way.

She was walking down a corridor coming back from the Halloween feast when it happened. She heard a noise coming from her left and, inwardly cursing the founders or Hogwarts for putting so many secret rooms and passages in a place that was meant to be for learning only.

As if teenagers wouldn't think of something... else... to do with those rooms.

She pushed aside a tapestry and strolled down the short passage that led to the corridor on the other side of the wall. She heard the sound again. Minerva had a decent idea what the sounds meant she was about to interrupt, but she had to get the students to bed now matter how awkward it was.

Her ears, perceptive due to years of practice dealing with this kind of shit, picked up on the sound coming from the repaired secret passage behind a large mirror.

She pushed aside the mirror and saw something she never forgot.

It wasn't like it was unusual for students to be found like this: one of his hands in her long hair, the other under her skirt and Merlin knows what he was doing , her hands undoing the buttons of his shirt, lips locked, her back pressed against the wall...

It was common, in fact...

It was more about the students themselves.

Draco Malfoy and Hermione Granger were the last people she would expect to find like this.

A pureblood and a muggle born.

The Slytherin prince and the Gryffindor princess.

Making out in a secret passage behind a mirror on the 7th floor.

Minerva weakly cleared her throat, awkwardly interrupting the passionately kissing couple.

They practically jumped apart in alarm and embarrassment.

As Minerva stuttered that they ought to get back to their dorms, only one thought went through her head

She was utterly shocked.
