The power of the completed gauntlet burned down the veins of Banner's arm. All six infinity stones, the power of a god, was already tearing his hulking body apart.

He had to focus. He just needed one moment to focus his mind and will everything back to how it should be. Stark was shouting something at him but it was hard to hear over the roar of his own pained scream.

"Just bring everyone back," Stark was saying. "We just need you to repopulate the earth."

... repopulate...

With all his will, Banner brought his fingers together and...

*snap*

The pain vanished, replaced by the pleasure of the tender caresses of Black Bride and Thordis Odindottir. Hulk blinked in the light of this new world. He was seated upon his throne in the Avengers Headquarters, his harem. The norse goddess, Thordis Odindottir, was teasing his mighty balls with her tongue, while Black Bride's red head bobbed away in his lap as she struggled to take even half his shaft into her mouth. She slurped hungrily but he urged her lips away before he came - his seed was far too valuable for her to consume.

After all, his harem covered the world, and there were 3 billion women in desperate need of his sperm.

Iron Womb was staring around at the throne room as if seeing it for the first time. As a fertility robot, she had the honor of collecting his seed, and often took the brunt of his loads, which dripped down her chassis and oozed into her joints and circuitry, making her act strangely.

"Banner, what did you do?!" Iron Womb gasped, clutching her steel, milk-dispensing breasts. She looked lower to the transparent glass aperture of her belly. There were no organs within - she was, after all, just a machine. There was just the clear fluid of her artificial womb, exposed to the world so that all could see the wonder of his progeny gestating within her. The only organic part was the reservoir of donor ova stored within her.

"Black Widow? Thor?" Iron Womb gasped, stepping closer to the throne. "Banner, whatever you've done to reality, you need to undo it right now. You've made me a... a... goddamn sex robot."

"You could have stopped at 'you made me' and still have been correct," Hulk sighed, staring at his favourite invention that was clearly malfunctioning. "Come here and let master take care of you."

The machine shook its head. "'Master'?! Oh, I don't think so, pal. What have you done with the stones?"

Hulk snapped a finger at the glitching servitor. "Iron Womb, return to original presets. Purge erroneous programming."

"No, wait-!" It froze. The lights flickered it in its eyes. Then in a sweet, electronic voice it said, "apologies, master. I was... confused."

With a wave of his hand, Black Bride and Thordis departed. Riding her repulsors, Iron Womb levitated towards the throne, landing upon his lap with her legs all ready spread in preparation, her armor plates and hip joints spreading apart as her machine body adopted a new configuration to readily accept his girth. As her vaginal aperture opened, he plunged his monstrous cock deep within her artificial womb, admiring through her abdominal window as it stirred the fertile gel inside.

She bounced eagerly on his lap, moving with machine precision to milk the life-giving essence from him. She was almost too good at it - certainly he'd never programmed her with a sense of foreplay, only the urge to breed as often as possible.

"Perhaps after I'm done with you I'll pay Pepper a visit," he mused idly. The businesswoman loved Iron Womb, and could spend hours watching the goo swirling in its midsection like a lava lamp. "She's been begging me to give Morgan a brother."

The machine paused mid-bounce. Seizing it about the waist, he drove it back down, mounting it fully around his three-foot cock, the hermetic seals of its pussy tightening around him so not to waste a single drop as a torrent of glowing green cum began to fill her belly in spurts.

Operating in an orgasmic standby-mode, Iron Womb went limp like the doll it was as he slipped it off his cock. He graced his hand over its belly, infusing it with a little of the time stone energy within him. The goo swirled faster inside her belly, and he smiled as her gestation period was shortened from 9 months to just weeks.

At this rate, he would soon have earth repopulated.
