Yes. Time to be aggresive with this girl.

Dr. Rossin was taken over by lust looking at this sexy blonde before him. Just the mere mention of those tits had given him a huge erection. The kind of erection he hadn't had in years.
"Betty... I want to give you this job... but I have to say I'm not convinced that you'd be enthusiastic enough to work here. I need the people who work here to show a certain dedication and desire"
Betty's giggles disappeared and she looked like she was about to cry,
"But Dr. Rossin... I swear I'll work real hard.. and I'll do anything that's asked of me"
Dr Rossin glanced at her beautiful mouth as she spoke the words,
"Anything my dear?"
"Yes Yes!! Anything! I'll be the best nurse on your staff"
"Very well then Betty to prove you'll be the best on my staff why don't you show me how to use that mouth on the staff I have right here"
Betty looked at the old doctor dumbly for a few seconds,
"You mean suck your... cock sir?"
He smiled and started to rub his erection through his dress pants,
"Yes my dear, if you suck this cock I'll give you the job."
Betty smiled sweetly and shook her head giggling,
"oh ok Dr. Rossin, I am willing to do anything to your staff hehe"
Betty stood up and moved behind to desk to where the doctor was sitting. She licked her nice full lips and slowly unzipped his pants. In one smooth motion she pulled his fat cock from his pants and into the open air of this office.
Dr. Rossin moaned as she slowly stroked it and kissed the tip getting a feel for his mature piece of meat. A tiny drop of spit landed on the purple head of his cock just before he entered her warm mouth. She immediately pushed his cock all the way to the back of her throat and sucked lovingly on the shaft causing the doctor to thrust into her mouth.
Betty did her best to handle Dr. Rossin's cock as he grabbed her head and roughly pushed in and out of her wet hole, sending spit and drool all over Betty's white blouse. Not wanting to ruin her shirt Betty quickly pulled it off so her spit would run onto her bare skin.
Dr. Rossin looked down to see Betty's huge boobs bouncing back and forth in a bra that looked 2 sizes too small. It was all too much for the old man and he exploded into her mouth.
Betty gagged and pulled back causing the rest of his cum to hit her neck and run down into her tight cleavage. Dr. Rossin quickly pushed Betty's mouth back onto his cock and she cleaned up every last bit of cum from the man she had met only 20 minutes ago.
Betty sat back on her heels and looked up at her new boss.
"Well Betty I'm a man of my word and you have this job young lady... however any word of this and you won't be working in this country. Understand?"
Betty smiled, "Oh yes sir! I promise I'll be the most loyal nurse you've got! And if you ever need me to prove it again... well I'll be here quite a bit"
Betty cleaned up and put her shirt back on. Dr. Rossin smiled to himself and wondered what kind of hospital this was going to turn into.
