Rape!? In my Harry Potter?!

Oh yes, another Harry Potter thread, but whatever. Someone earlier mentioned there had been rape in Harry Potter, it's been a while since I read the books (except for 7, which I finished yesterday) and other than the whole "SOMETHING TERRIBLE HAPPENED TO ARIANA NOBODY TALKS ABOUT LOL" I can't think of any other scenes that might've suggested rape.
Enlighten me.

Also, ITT, we pay our respects to the fallen characters. And if you're on 4chan, you're bound to bump into spoilers. So if you don't want spoilers, GTFO the interwebz.

Professor Snape furiously ripped away Hermoine's undergarments and hosed her down with yellow and musky warlock piss. The imperious curse kept Dobby to the busy work of stuffing his green goblin ass with a splintered bedpost. Snape twirled his wand and hexed her little tits to produce troll's milk, in which the professor fed most hungrily, filling himself like a tick.
