Hello, after insertion just press and hold on girl's face or plevis and move up down until she climaxes (the heart icon above becomes full). Repeat this again afterwards to unlock cloths menu. Mind break the girl (fill the pink circle around the heart) to unlock new features.
UI can be toggled on-off via top left corner button.
If the issue persists please record the screen and send the video to my email nymphokyun@gmail.com.
I hope this helps,
