Eureka!

Zack opened his eyes and looked for his glasses to see Power Girl cuddled up next to him, her legs wrapped around his waist. Long gone were the days of waking up alone and sad in his empty house. When he tried to wake the hero, he heard Poison Ivy, and she energetically jumped into the room.

"Eureka...Eureka...I've got him!"

The joy that overflowed from the supervillain was so great that it seemed like she had just taken over the world. Of course, her screams made the Kryptonian wake up somewhat startled.

"Something bad has happened," Karen said, putting herself on guard.

"Quite the opposite, Mistress. I'll finally be able to finish my experiments to increase Owner Sex-Man's powers...look," Pam spoke to her, throwing herself onto the bed.

"That's what you have?" Power Girl said expectantly.

In her hands, she held a sophisticated device similar to an injection gun or a pistol with a red liquid at the end of the needle.

“Seriously, ****… What will she do to me?” Zack asked curiously.

The redhead’s eyes shone, and a proud smile appeared on her face. She was excited and happy to demonstrate her usefulness to her man, to make up for her crimes against him.

With her usual sensuality, Poison Ivy crawled toward Zack, staring at his half-erect cock. She didn't hide her eagerness to receive her white reward.

“I’m not going to confuse you with technical details… but I will say that it will be a catalyst that will amplify the fabulous powers of Super F three times over…”

In one agile movement, she placed her green hand on her Owner’s cock and slowly masturbated him while looking at his face, seeking his approval. Her skills were such that she could easily get him hard with just one hand.

“…your incredible pheromones will be more potent, making it easier for you to captivate your future slaves without having to use the red smoke…”

Taking her time between her explanations, Pam dragged her green melons down her lover's chest, her lips a millimeter from his.

“...your vigor and libido will also increase considerably. You'll be even more unstoppable in bed than you are now…”

She increased her manual labor while simultaneously beginning to sniff him like a bitch, all without losing the thread of the conversation.

“...of course your incomparable semen...Sniff...will be much, MUCH more addictive to females...Sniff...what's more, you'll gain a new power, my beautiful Owner.”

Her words and her masturbation had Zack on the verge of insanity. All this time, Karen had watched them, excited; her jealousy long since replaced by voyeurism and a hint of envy.

The desire to eat Poison Ivy was fierce, but he had to maintain order to show his whores who was in control.

"Okay... Pam, but stop right now," he said sternly.

"But... but Owner... I..."

“Stop... that's an order. If your experiments work, you'll have your reward,” he said more firmly now.

Despite her sadness, Pamela obeyed, separating from Zack and releasing his penis. She clearly wanted to fuck, but she knew she had to follow orders. Our protagonist liked the level of submission that had reached the once threatening villain; the continuous hours of unbridled sex had paid off.

“Not bad, you know how things are... Owner first, and lord later...”

“... the **** whores,” they both said in unison.

“Okay, let's see if it works. You did the work.”

Zack confidently extended his right arm so Pamela could administer the liquid.

“Are you ready, Owner? You'll feel a little pain,” the redhead said.

He felt a sharp sting at the injection. He saw how the red liquid quickly disappeared as its contents reached his veins. Expectantly, he felt a warmth in his arm that spread to the rest of his body....
