Just take it a bit easy, try and see what she wants.

"Umm... Thank you, I guess..." The girl smiled at my compliment, with that cute blush rising on her cheeks again.

"And how about you?" I asked, still chuckling a bit. "You always walk up to people doing strange things and ask them what they're doing?"

"No, not at all!" She giggled nervously while glancing down at the still obvious bulge in front of my pants. "I... I don't know why really... I was just so surprised, and then I... got curious, I guess..."

"Heh, nothing strange about that!" I grinned at her. "But it's damn brave of you to come up to me like this, after what I did I mean!"

"You think...?" She wondered, still blushing while looking both surprised and a bit proud of herself for doing what she'd done. "I... Noone has ever said that about me before..."

"But you are!" I assured her, looking back into her beautiful dark eyes as she gave me a shy little smile. "You sure you never did anything crazy like this before?"

"Well, no..." She said, biting her lip and then nervously looking around in the car as if worried that someone might be listening. As she spoke again, her voice was even lower than before and full of tension. "But... I don't know why... But I always wanted to..."

"Do crazy things?" I smiled back at her, watching her face go red again as I didn't care to lower my own speak. "Like what?"

"Well..." She started, again glancing around while letting out another nervous little giggle. "Like... flashing my tits at someone...?"

Finally I realized why she'd sought me out in the first place, wether conciously or not, and immediately felt that I was getting on more familliar type of ground. Now all I needed to do, was to just hum along and wait for the right moment...

"I... I don't know why really..." She continued her confession, barely daring to meet my eyes as she spoke. "It's just this strange idea I got... Like I want to... show people what I got...!"
