Kalli is wearing a tight shirt and she is ripping it with her muscles! This is the video you have all been waiting for. Kalli has huge bicep peaks and the shirt is so tight that even bending her arm will rip it. She starts off not flexing, just moving her arms which is stretching the sleeves. She then flexes HARD to rip the shirt, which you will see and hear the shirt rip. after some more HARD flexing, Kalli rips the shirt to shreds, and tears it into pieces!
