Hit

You finally decide you want to see how swollen they can get. With a malicious grin you let his balls go and step back from him. He gives you a hopeful look but it disappears as your machine springs to life.

Without hesitance, a first forms from your robot and it adjusts to the appropriate height. The man is watching with wary eyes and they widen as your machine surges forward. In a split second, the fist pumps forward and nails him right in his nuts.

He chokes on a scream of pain and the fist pulls back and allows you to assess the damage. After his balls stop swinging you notice that they are already bruising.

"Powerful, right? You took quite the hit. Let's see how many more you can take."

You enter a command and your robot obeys. The fist pumps back and forth like a piston, hitting his balls with deadly accuracy. The meaty thud of an impact is accompanied by his screams and cries of pain. His tender balls flop and swing but they won't escape your lab intact.

You allow a moment of rest for the man, so you can pull up and chair and get more comfortable. Undoing your pants, you let your hard cock free and the man notices. His face is as red as his balls and is tear stained, "You sick fuck, you're enjoying this?"

You only grin as you enter a command, telling your robot to continue. "Yes, I am."

The fist begins pumping again and the man is screaming once more. His balls are swollen and red, bruising horribly. The two orbs are so ugly now, mishapen with the **** they've suffered.

Really, to leave them intact at this point would just be...cruel. You laugh and the man is thrashing in his constraints.

"Please!" He down right sobs, "Please stop!"

The heat in your stomach is coiling and becoming tighter, you are so close to climax.

You give a small, reassuring smile. The man gives you a hopeful look. His face is red and tear stained, his balls are so swollen and bruised they barely resemble balls at all.

You pick up the remote and enter the final command. "Say bye-bye to your balls."

In an instant his face contorts to rage. "You sick fuck! Fuck yo-!"

He stops speaking and his screams come back in full ****. Your robot is downright beserk now, hitting with effortless ****. The balls are swinging with each impact, the smack of flesh meeting metal barely heard over the man's shrieks.

You find yourself cumming just as your robot gives the final, devastating blow. A swift upper cut that forces his balls against his pelvis, trapping them and only allowing the pressure to build. His shrieks are the highest they've been and are accompanied by two loud POPS.

His eyes roll into the back of his head and he passes out. Your robot, with its task complete, dutifully returns to your side and rests. The man's sac drops, but the balls have turned to mush. You let out a breathless laugh. You SO have to do a second test.
