You lift up her skirt.

You take her panties off your face and drop them on the floor. She watches you do this while laughing hysterically. You quickly reach out and lift up her skirt exposing her shaved pussy. She stops laughing, and clamps up her mouth tightly. Her eyes are open very wide and she has a look of shock and surprise on her face.

"Hey!," she says knocking her skirt down with her right hand. She stares intensely at you with a serious look on her face.

"I can't believe you did that," she says, "What are you some kind of pervert?"

"Hey," you respond, "You did the same thing to me."

"That's different, silly," she answers, "I'm a girl."
