Power Sex Armor

Lex didn't look at the monitors as he disrobed, but the speakers brought Mercy's pants and moans loud and clear into the laboratory, as if she were right in the room next to him, getting her holes eaten out by the eager tongues who should be in the preparatory chamber for the next stage in the experiment right now.

Nude, he stood in front of a green and purple suit of metallic armor. A Kryptonite-powered exoskeleton, powerful enough to enhance his strength, speed, and durability to the levels of Superman...for a time. His penis throbbed as Mercy's moans struck a new tone. Lois must have inserted another finger.

"Open sesame," he said aloud, and the power armor cracked and swiveled along hidden seams. The interior was cushioned, like a personal coffin. A hard metallic prong rose up from the rear in a gentle arc. It began to secrete a clear lubricant, waiting for Lex's insertion.

Lex turned around, and using both hands spread his cheeks. He pushed gently against the synthetic prick, not wanting to injure himself, and sinking once again into the familiar fullness he always felt when in his battle suit. Easing down carefully, right to the hilt, the billionaire genius felt his ass press against the silky interior cushions. "Close sesame" he said aloud—and the suit began to close around him. He slipped his arms and legs into the waiting holes, the chest rose over and onto him, and the smooth, wet, warmth of the sheath slid over his raging cock. In seconds, he was sealed once more within his armor, and strode forward, clanking softly against the floor.

Learning to walk in the power suit, with its anal interface prong and the penis sheath, had been difficult. Ever step was like getting penetrated and penetrating at the same time. The constant sensation of the thing pressed against his prostate had driven him to distraction in its first few outings against Superman, and the alien had mistaken his sexual excitement for physical exertion. Now, however, Lex felt that he was in better control of it. The interface prong connected with his autonomous nervous system, allowed the armor to react to his instincts without delay. As he strode down the hallway and up the stairs, steps clanking all the way, he surveyed the suit status.

The original design had used green kryptonite as a power source, to take advantage of Superman's weakness; this version however used several separate kryptonite power sources, each with different colors and effects. The purpose of the retroviral experiment was to test what effects those different frequencies of radiation would have on Kryptonian anatomy, to avoid engaging with Superman or Supergirl directly until Lex knew exactly how to transform and overcome his enemy...

But now he had test subjects upstairs, still unsecured. It was time to make this a hand's on test.

"Tell security to lock the entrance to the bathroom. I don't want any interruptions." He began priming the suit's weapons. Crotch-mounted phalli-tentacles. Synthetic Kryptonian hormone aerosol bombs. Anti-spermicidal nanite sprays that could counter all known birth control methods in seconds. A retractable ultrasonic vibrator that even Power Girl couldn't withstand.

Yes. Lex thought to himself as he opened the maintenance door into the bathroom, and heard Mercy scream in pleasure. He was ready to fuck.
