Yes

As she jerks quicker and quicker, you sense that you are about to cum. However you managed to gasp the word "Yes" before...

...before she stops completely.

"You are a liar." She gave you a sadistic smile "and this cannot go unpunished!" She reached over and grab a surgical knife that was on the trolley with one hand and grabbed your whole package with another. "I would have given you your final release if you told me the truth." She grinned "Your average sized cock is boring. Let me make it exciting for you."

Without hesitation she yanked your dick as hard as she could and sliced through it just below the crown. She has taken the head clean off

You are less of a man.
