Metallo

At first, Lois Lane thought a metal skeleton had walked through the door. Then she saw the servos and motors around the arms and legs, the strange artificial eyes, the broad metallic chest that had some sort of door set in the middle...and her blood ran cold as she knew she was looking at Metallo, the Kryptonite-powered cyborg. One of Superman's deadliest foes.

And he had a cock.

The naked reporter shivered as she saw the ribbed metal beast sprouting from between those legs. It didn't look like a human penis at all...something closer to a high-end rabbit vibrator, a little prong jutting forward like a scorpion's stinger to attack the clit...and yet it was covered by little waving silicone fronds, like a sea anemone.

Lois clenched her pussy instinctively, the shattered remains of the dildo crunching as they were broken by the power of her pussy.

"I see the treatment has taken effect," Metallo's electronic voice was an ugly, artificial thing, like snippets of a real human voice patched together and mapped onto other frequencies. It was less refined than the voice of a car's navigation system.

"What treatment?" Lois said, feeling her muscles bunch as the villain clanked closer. "What are you doing here?"

"We are field-testing the effects of Kryptonite on Kryptonians," the metallic voice had some underlying frequency that made it grate on the reporter's ears. "Under controlled, laboratory conditions. All kinds of Kryptonite. Green...Red..."

The doors on his chest opened, and a pale silver light spilled out from a metallic mineral held where the cyborg's heart should have been. Lois shrank back from the light, feeling her skin tingle with a pins and needles sensation...

"...and Silver. Do you know what silver Kryptonite does, Lois?"

Fear ran through Lois, acute panic freezing her in place.

"On Kryptonians, the effect is similar to cannabis...only without needing to wait for inhalation or ingestion to take effect. No, the effects are much more immediate, cannabinoid-analogues produced directly in the blood stream."

Parts of the dildo began to spin and rotate.

"The immediate effects are psychoactive. Increased anxiety, euphoria...and libido."

He was standing over her now, the mechanical cock pulsating and rotating, strange anemone-arms flailing. He reached down with one cold mechanical hand to tug the broken remnants of the dildo from her pussy.

"Can you feel it, Lois? Be honest, please," he leaned down, face hovering only inches from hers, strange electronic eyes boring into her own, the silver light hot and bright on her skin. "This is for science."
