Scene Description:

Slytherin slut Draven Star has some filthy study tricks to drill into Ramon, who's slacking hard on his O.W.L.s and wasting time on lame transfigurations instead of brewing up something potent. Since he's not in the mood to study, she hits him with a throbbing boner spell that makes his cock pulse and strain, then drops to her knees to choke it down her greedy throat before spreading her soaked muff wide and swallowing every inch like the filthy Hogwarts Headmistress she is. She rides that twitching magic wand balls-deep, grinding and clenching until they're both guaranteed to pass with explosive, dripping colors.
