Crush

Well, you really are impatient. You've waited such a long time to test your creation, why not go all out? And so, with a devilish grin, you take the control and give a single command, "Crush."

The man stares, confused, until you step aside and the robot surges forward. In one quick motion a fist comes forward and takes the unprotected sac in hand. The man gasps in surprise, than shrieks as the metallic hand closes.

The man thrashes in his bindings, even begins sobbing and pleading, but it is all for naught. You aren't letting him go until both his balls are busted.

His balls are swelling in the fist, turning bright red and trembling under the pressure. You move closer, so that your face is only few inches from the abused sac. Your cock is straining in your pants but you are too transfixed on the sight before you to look away, even for a second.

The man is screaming but has stopped fighting. Now he just withers in agony as your machine brutally castrates him. As YOU brutally castrate him.

His sac is turning purple now and the two nuts are nearly at an end. You laugh, excited for the big finale, and don't even realize what has happened until the back of your head hits the floor.
