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 little man." 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 "Besides, your small cock gene must not be passed on"

Without hesitation she yanked your sac as hard as she could and sliced it at the base with ease. Your balls drop out and she severed the cords with a flick of her knife.

You are no longer a man.
