She wasn't doing it to be mean, the first time.
There was no evil punishment in mind for some misdeed. It was just happenstance.
One moment Mary Margaret had Emma pressed up against the kitchen counter as Mary Margaret knelt between her legs. Emma had been right on the edge, Mary Margaret's fingers shoved inside her, her mouth on Emma's clit, and Emma's phone had gone off. The official police dispatch tone that she couldn't ignore.
The poor sheriff had been forced to leave right then after answering, no time to cum and no excuse to linger. She'd returned hours later a needy mess just begging for anything Mary Margaret would give her.
That's when it became an idea.
That's when she used it against Emma.
When Emma was being a particular pain, intentionally annoying or disobeying a rule, Mary Margaret would make sure to get her worked up right before she had to leave for work or for any reason. Before long she didn't need an excuse, she'd just stop and watch, waiting for Emma to realize and apologize for her wrong doing.
Mary Margaret knew that Emma could just finish herself off easily given how close she'd get her before leaving.
But she also knew she wouldn't. Anything Emma could manage with her fingers wouldn't be near as good as her reward if she suffered her punishment like a good girl and apologized sufficiently.
Besides, every punishment was deserved.
Even if the rule broken was made up.
