The punisher becomes the punished

The League had a saying. 'Only a student has hope of defeating the master.' The intent was simple enough, one who learns all the techniques and skills of another will inevitably be able to surpass them. The way around that was for the teacher to learn as much from their student, to always be willing to learn.

Such was the lesson, and such was League tradition. Any mentor, should they make an error, was expected to acknowledge it, and so the student would become the teacher. It wasn't anything shameful, if anything it was something to be proud of, a willingness to always learn more.

An honor system kept the tradition in place, but honor was everything to the League.

One application would be... well, if a mentor put down a punishment for one they taught, and it was agreed that the punishment was disproportionate or unfair, even if unintentionally, then that would be cause for the mentor to learn. In practise, it meant the student would set a punishment to make up for the gap between what should have been, and what was.

"Do you think it was fair?" Sara said, playful.

Nyssa's cheeks warmed.

The worst part was, Sara was entirely justified. Half an hour of being naked, and worried, but likely not seen, was what she'd intended. Instead Sara had been exposed to dozens for a week. There was quite a gap between the two.

A gap that Nyssa would have to be punished for. Nyssa swallowed.

She could refuse, in theory. But she was Heir to the Demon, it was on her to lead by example, to hold to the League's rules and traditions, even when...

"No," Nyssa said weakly. "No, it wasn't."

"So, unless I'm very much mistaken, that means I get to set some suitably fitting recompense for you," Sara said.

"...Yes," Nyssa said, voice small.

Sara smirked.

"Proportionate to what happened," Nyssa said quickly.

"Oh, of course," Sara said. Her eyes glinted. "And if it's too much, I guess you'll have to take it out on me. Though if that goes wrong, ooh, it's your turn again..."

Nyssa's cheeks warmed. She still lay on the bed as Sara idly toyed with her sleepwear, a simple practical layer of fabric. She unwrapped it almost tenderly, exposing the familiar sight of Nyssa's naked body.

Somehow, Nyssa had the feeling her 'punishment' would involve nudity.

"Well?" Nyssa said, nervously. "What do you have in mind?"
