He's thrilled. Nadia tries to upsell.

Nadia realised that at some point while she was blowing him, Mr. Simmons had pulled over and parked. He was leaning back on the seat, gasping as she lapped and licked at his cock, cleaning him off before looking up at him with mischievous grin.

"That's what I like to do for fun Mr. Simmons! Did you have fun?"

"Holy Fuck! Yes! You're incredible!"

"Mmmmmm I like being a nasty little slut Mr. Simmons...I like sucking a big fat hard cock...so good...I love being a bad girl..."

"You're not nasty, you're very sweet," he said, "Don't say that about yourself."

"But you loved when I sucked your big fat cock with my nasty slutty mouth," she giggled, squirming up and nuzzling his throat. "I could feel you get harder when I started to gag on you." As she squirmed she squeezed his cock with one hand, working it's flaccid length. "Can you get hard for me again Mr. Simmons? My teenage pussy needs filling, it needs it so bad."

"Christ...I don't know...it's been years...and besides I'd have to pay double if we did it again, right? Isn't that how it works?"

His question took Nadia by surprise. She had thought the deal was two hundred to satisfy him, and sucking him off had made her wet and horny, but if he was willing to pay extra for fucking her, she wasn't going to say no.

"Well...normally....but maybe we can work something out...I am pretty horny...what if you paid another hundred and fucked me silly with this...I can feel you getting harder Mr. Simmons...I know you want to fuck my tight wet pussy."
