Spit

You know you provably should give in to your reflexes but you can't stop yourself from reflecting on this situation. And while you did enjoy the taste if you're honest, you can't help but **** on the thought of having a man's cum in your mouth - the hot goo that your boss shot into you sticks to your uvula and your tongue - it's not a physical reaction, your body seems perfectly capable of handling his load, but a mental blockage. It makes you cough and you spit his semen out, it dribbles down your chin and on to expensive carpet between you and his desk. You look up at him.

“Sorry, Sir, I didn't mean to…”

He laughs.

“Don't worry, girl, the cleaning ladies are very skilled at getting cum out of my carpet. I’m not surprised you're not the most skilled cocksucker. Yet. But I see the potential. You’ll learn and put your skills into the service of the company."

You look up to him, happily and grateful for is understanding.

“Thank you very much, Sir, I’ll do my very best!”

“I’m sure you will.”

He puts his shrunk cock back into his pants, pats you head.

“I’ll see you tomorrow then!”

You stand up, straighten your clothes and leave his office.
