Time stop

With time frozen, you strip Savannah, then stand off to the side and restart time.

Your timing is perfect, as she snaps a selfie before realizing she's naked. Before she sees you, you stop time again. You pick her up and put her out into the hall. You take her phone then close and lock her door. You restart time.

You hear a cute yelp then the sounds of someone frantically trying to turn the door knob. You ignore that and go through Savannah's contacts, and find a group chat for the cheer squad. You post the nude selfie on it with the caption Who wants to cheer naked?!

You then hide her phone in a drawer and unlock the door.

Savannah rushes in, and you stop time again as she closes the door behind her and before she sees you. She is blushing deeply. You look at her naked, taut body.
