"Shit!" Casey screams as she starts to squirt.

"Take it bitch!" Riot laughs as the people around her boo.

Riot then starts to fist Casey faster and harder until Casey screams, as her head feels like it on fire from the beating she got, her body starts to shake and she inadvertently starts to tap her hand on the pavement which signals to everyone she was tapping out, while she squirts again.

She gets on her motorcycle and flips the people the bird again with the hand that dripping with Casey's pussy juices, "See ya suckers!"

And then drives as Casey lies there panting, she then looks at her shaken hand, "Traitor."
