Make her beg for it

Francis stops in his tracks and the blonde woman is spun about. She looks confused. She just promised him head, after all.

The blonde woman looks paniced.

"Please!" she cried. "I really want to blow you! Just come to my car and I'll let you do whatever you want to me!"

"I don't know..." said Francis. "You were pretty rude to me before. I don't know if I trust you."

"But...but..." the woman stammers. "I NEED it! I NEED your cock!"

She falls to her knees.

"Please! Please! I'll do anything! I'll pay you! I'll be your ****! Just let me touch it! Taste it! Serve it! PLEASE!"

Francis grinned down at her. He'd never expected to have a woman say that to him before--certainly not in public. He was about to give the poor woman a break and let her suck him off before she started crying when he heard a voice from behind him.
