Sleeper Agent

“Hermione, when I say ‘go’, you will fall asleep and forget everything about tonight. You will wake up tomorrow morning and behave and feel as you normally do, and will not have any clue that you’ve been Imperiused. Every time you hear the phrase ‘points to Gryffindor’, you will become aroused, with the severity increasing by a percentage equal to 10 times the number of points you or your classmate has received. When you hear someone say ‘X points from Gryffindor’, you will orgasm X times 10 percent harder than you have ever orgasmed before. Do you understand?”

Hermione stares blankly, but nods.

“Good. Now lie down, and go to sleep!”

Hermione instantly collapses on her bed, snoring like she had never woken up. Luna ducks away and returns to her own bed, eagerly awaiting the morning.
