Your bratty teen 18+ step-daughter hates to study, she will make up any excuse not to!
You punish her to teach her a different kind of lesson.
She will need to finish studying if she wants to go out later with Step-Daddy and his girlfriend.
In the middle of studying, she asks to take a pee break.
She should have gone before!
If she wants to go now, she will have to use the chair as her toilet.
But Step-Daddy loves to see her in her nylon pantyhose, his sexy girl never wears them with panties.
So... She's not allowed to take them off - she must piss all over them ...

She has spent so much time during her pee break, and there's no time to clean up before going out.
She must stay home and finish up her studies in her soaked chair and clothes, a fitting punishment.
She complains and pouts, Step-Daddy is so mean!
