"Hey, Kimmy, let her go a sec."
The red-head's grip slackens as Tina continues, "I want to see her do it herself... That's right, loser. We all know what a dirty little shame-slut you really are, so work those panties!"
Kimmy abruptly yanks on your hair, snapping your head back and forcing a startled cry from your throat. "Better do it," she growls, "or I'll shove my whole fist up your peach."
With trembling hands, you grip your panties.
[Begin rhythmically tugging the front of your panties.]
"Look at you go! Why don't you stroke your flower for us? You know you want to."
[While jerking your panties, begin stroking with your free hand. Press the fabric deeper between your lips.]
