"Excellent, let's take them for a test." Luthor grinned as he brought up a map of Gotham. Mercy turned to leave when Lex stopped her. "Oh and Miss Graves, we have a martian problem, you'll find your new work uniform in you locker, I trust you can handle him."

"Yes sir," She said before turning on her spiky heel and exiting.

Over the map of Gotham three pictures flashed. One was the Huntress in her black and purple spandex costume as she investigated the mob. One  was Robin as he watched Poison Ivy. The last one was Oracle, it had taken him weeks to hack into her clocktower but now he had all the information he needed.

Superman flew off with the pimp in hand leaving the girls to their own devices. Lo-Lo set her toy back into her purse with disappointment. She would have loved to screw with Clark after everything she had had to put up with, but it was better this way. Lex wanted to pull the wool over Superman's eye personally.

All of the whores walked back to their corners giggling, their pimp would be out soon to take care of them. Lo-Lo walked out to the street looking for some cock. Her pussy was dripping with anticipation at fulfilling her role as a whore.

Mercy Graves looked at her assigned outfit. It was a rubber black mini dress with matching opera gloves and thigh high boots. She had been given a whip and a cigarette holder along with a lighter to deal with Martian Manhunter.

Meanwhile Lex examined his new conquest Mary Marvel. He had been surprised at how readily the training had taken to her young mind. After hours of soft core porn and brainwashing she had turned into quite the conniving slut. She was currently sucking off a married man while his wife watched on horrified. 

"Are you ready dear?" Lex asked looking at the new Marvel. Mary moaned around her man's dick before it came in her throat.

"Oh yes Mr. Luthor!" She said as cum dribbled down her chin. "SHAZAM!"

Where the young Mary had kneeled Mary Marvel stood. Her new outfit looked like a combination of her old uniform and a school girl outfit. The lightning bolt only remained as a necklace that dangled in her supple young cleavage. Her skirt was shorter too but still innocent and her blouse was short enough to expose her bare stomach and belly button piercing. This was phase 2 of the plan, while Lex began to corrupt heroines Mary Marvel would go out and seduce all the heroes in a relationship isolating the rest. Where Lois Lane had been surgically enhanced to ooze sex and sluttiness Mary Marvel had been made to look like the picture of innocent temptation.
