Mysterious Blue Drink Makes My Ass Shake on Its Own in Doggy Pose

Description: I took a sip of that weird blue drink again, and this time it didn’t just mess with my chest—something hit my lower body. i got on all fours and suddenly my ass started moving on its own. i wasn’t even trying. it just kept shaking and bouncing like it had a mind of its own. i couldn’t stop it… and honestly, i didn’t want to.
