Katie gets even by ripping off Cat's skirt . . . who is wearing panties -- a tiny thong

Katie's cheek flushed red as everyone could see her pussy. But she wasn't going to stand for the humiliation this time. Quickly she jumped off of Samantha and Cat. She was behind them. Before Cat could turn around Katie grabbed onto her miniskirt and yanked it down, revealing her tiny pink thong.

Katie didn't bother to try and cover her body. She was focused on Cat, along with everyone else.

How does Cat feel?
