Yells at him

"What the fuck, you pervert!" the girl screams at him. She is waving her finger right in his face. "First you follow me around the mall, now you're creeping outside by my car playing with yourself? What kind of sicko are you?"

"I'm...I'm sorry...I, uh...."

He knew he should be concerned about this, but that was when he realized she wasn't wearing a bra under her white tshirts. He could make out her nipples and the curve of her small but perky boobs through the fabric. They bounced every time she waved her finger at him.

"I'm up here, asshole!" she yells and he pulls his eyes away from her breasts. "Is this what you do? You think just cause you have a big cock you get to expose yourself to defenseless young women?"

"I'm sorry, I didnt...I promise...I didn't realize you were parked here," he stuttered.

"Don't lie to me," the girl said. "I saw you walking around the mall with a hardon, staring at my ass. Now you're at my car, jerking off?"
