Katie gets even by ripping off Samantha's skirt . . . Samantha isn't wearing panties

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 Samantha could turn around Katie grabbed onto her miniskirt and yanked it down, revealing her pussy.

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

How does Samantha feel?
