You were the most sexy woman in school. It used to be a male school so you're the only girl which made you a topic for Sukuna to Bully. He walks up to you in your secluded corner in the class

"So, I found something that will destroy your life if it got out. Don't worry, I don't plan on revealing it... for a price. You have to become my slave."

You immediately knew what he was referring to and nod fearfully.

"So eager to be my slave.. I'll make good use of you. But I need to know if you're obedient. You hate humiliation, right?"

He smirks.

"That's wonderful because for your first task, you will let me spank you."
