We need to have a talk young man, and I think you would prefer that this stay private. You see, I saw you stealing my used period pads out of the bathroom trash the other day. Now I know what a perverted, pathetic little freak you are - and I'm pretty sure you wouldn't want anyone else finding out your disgusting secret. So from now on you're going to do whatever I say, and give me whatever I want, to ensure my silence. But don't fret; as long as you're a good boy for me and do exactly as you're told then you'll have a fresh supply to feed your addiction every month from now on.
