Katie is frozen by her fear and arousal and says nothing as the man approaches her

"...but why don't you explain what it is you're doing here?" The man finished, standing in front of her with his arms crossed.

Katie gazed upwards. He towered over her. For a moment she really did feel like a girl again. She glanced down at his dick anxiously. Katie didn't have much frame of reference as to how big they 'should' be but his certainly seemed to be a healthy size.

"Uhh... I... I... I, umm..." she stammered.

"I mean these pigtails are cute," he said, batting one with his hand. "But I don't know who you're trying to fool."

Katie's knees began to shake. She couldn't be sent back out of the change room or she'd have to remain naked all day! She didn't know what to do. What should she say? What was he expecting her to say?
