fwee, Sevikas mouth went. A whistle.

Your brain short circuited for a moment. Sevika used whistles while working for Silco to communicate with coworkers. Different ones with different meanings. Yet this soon carried over to your relationship with her. You started to catalog each one in your head and this one, it meant a warning. Not for real danger, a warning that you were testing her limits or being a brat.

She smirked, waiting, when your once bratty and sassy mouth went quiet.
