Halo Infinite spoilers, you've been warned!

Unfortunately, 343 doesn't provide an early copy to smut writers to make sure the early stories are accurate. It's a shame, really.

This was a fun little story to do in celebration of the Halo Infinite final release. I hope you enjoy it, and that I didn't get too much lore wrong! I plan on playing the game, so maybe I'll edit the chapter to be more fitting after that and write another one with more fun between the two characters! :D

After the countless missions across Zeta Halo, there was finally hope of changing the tide of battle. The Banished were relentless in their pursuit, each one of the apes eager to take the glory of killing the most dangerous Demon to live. None succeeded, and none would anytime soon—for there was still a battle to win. As long as there was a single UNSC soldier left, the fight would go on. Humanity's spirit would remain unbroken, and Chief was the living example of that. His armor was made from the blood and sweat of miners, soldiers, and researchers, all working towards a common goal, united in the last stand against the alien threat.

Master Chief was more than a capable soldier, but there was only so much he could do against the entire Brute armada. For every fuel station he destroyed, for every team of marines he rescued, the Banished advanced to their goal. He needed help. The monitor of this installation was the only hope and crucial to their success.

Luck wasn't on his side this time. Just as he found the monitor called Despondent Pyre, unknown assailants attacked it. Small flying species that were an annoyance in small numbers, and only a real threat if they were overwhelming. Nothing his rifle couldn't handle.

The installation's caretaker was still captured despite his hardest attempts, and all John could hear were the robotic screams while an unfamiliar voice was trying to get information out of the monitor.

"Chief? I'm reading some very strong readings just about... there," his new companion, the Weapon, said. She pinged his visor to the metallic vault. Various pillars spun around a central point, rotating with increasing momentum, as if guarding it against outside harm. At the very middle, there was a brilliant light, too strong to show what the ancient technology had in store.

"Show yourself. I know you have been following me," a feminine voice called out to the Spartan. A single sentence, but it held an incredible amount of authority. A less experienced marine might just listen to such a request and surrender. Chief knew better, aiming the barrel of his bulldog shotgun towards the source.

The Harbinger. Her body was more akin to a machine than a living being, covered in dark red armor that looked surprisingly light for a figure of this importance. There was a burning core at her chest, likely the source of the light that was covering the entire chamber just moments ago. The alien levitated in the air, looking straight at her newest visitor. The newest thorn in her side. It didn't have to be this way. If only he had known the entire truth, if only he shared her vision. She would make him see. He was too useful of an asset to destroy.

"We are not enemies." Instead of attacking him and destroying him in a single strike, The Harbinger had different plans. This was an act of mercy, and with enough luck, the Reclaimer would see it as such.

"Despondent Pyre?" This had to be the alien John heard torturing the monitor not so long ago. The fate of that machine was now unknown, and the target floating before him was the only clue of finding out what exactly happened. A monitor is no easy foe to take down. Master Chief had the unfortunate luxury of finding that first hand.

The pillars spun again, pushing the spartan to be on full alert. Hardly the first time the mission didn't go according to the plan.

"She had something I required," the lady in crimson replied, showing a hologram of the real target he was after. An artifact of most importance, and it was floating between her hands as if it was a toy. Whoever she was, she was in control of the installation now, at least some of its systems. She slammed the hologram into the ground, releasing a blue shock wave that in an instant locked down Chief's armor.

The Harbinger was close to her goal. All that was needed was a Reclaimer. The timing couldn't have been better.

"I know of you, Reclaimer, but hear this..." Her body hovered right before his paralyzed armor, almost taunting him with how close she was. A round or two of shotgun bursts and this would all be over. If only he could move even a muscle. "You are not the future. Us, however?" Her gaze landed on the same hologram, which made its way back into her hand. "We just may stand a chance."

"You okay, Chief? I'm trying to get the armor—" the AI was cut short, along with any hope of the spartan getting out of the stasis.

"There. Now we shall remain uninterrupted. The Forerunner's lies are at the end. I am the Harbinger of the truth. And you? You shall be my Reclaimer." Her armored hand moved to the side of his helmet, making sure he stared right at her. Into the pair of dark red eyes that only held the vision of a far grander purpose.

John struggled against his powered-down armor, but it did little besides straining his muscles. Cut from the outside help, almost entirely on his own on this installation, there wouldn't be any help coming anytime soon. Perhaps the Weapon could get him free, but there was no way to know how long it would take. He was on his own for now and had to roll with the punches, just like always. Buying time until his chance was a priority.

Instead of going for a monologue or trying to finish the kill like the soldier expected, Harbinger's gaze continued to pierce through John's visor, never once looking elsewhere. The initially curious look on her face morphed into a frown.

"Lack of a reaction is only a reminder of what mindless beasts I have to work with. Having someone competent that can take orders without a snarl will be the most welcome change. Now, let us begin."

With a single motion of her hand, Chief's entire body felt weightless. Soon after, he floated, reaching a few meters above the ground before stopping. Just like a puppet on strings, his arms and legs were moved against his will. Harbinger had little trouble manipulating a suit of armor. His legs were spread out, the same went for his arms. Despite how weightless he felt, the steel grip she had proved unrelenting. John still could not move even a finger. The alien woman—pleased with her work if the smirk on her face was anything to go by—floated closer again. The key difference was the position of her head. Before it was face to face, but now she was a lot closer to John's legs.

The Harbinger tapped his belt, and just like that, the armor around his crotch digitalized. It was reminiscent of what Promethean weaponry did to one's body. John braced for pain, still wrestling against her hold, but none ever came. The black under-suit he had beneath the metal plating was now revealed to the alien woman. She leaned in closer with a hum, forgetting her manners for a second. This human was an incredible specimen.

"Worry not. This is only temporary. I would not damage the equipment of my new ally on a whim," she mused, softly tracing her four-fingered hand around John's covered length. The smallest touch through the under-suit was enough to spread warmth throughout the entire region. It's been far too long since she indulged herself like this. Nobody was worthy enough of her attention, but humanity's champion, the Reclaimer, might just fit the bill.

The touch only got more brazen as the time went on. The Harbinger was moving her fingers on the bulging shape, smirking at how quickly it grew. "It seems we both need this. Pleasures of the body are so easily forgotten when there are far more important matters pressing." The silence from her partner didn't bother the alien woman. Any weaker man would beg for her to stop, or needlessly struggle. It only proved that she was right in picking Master Chief.

A single tap on the glands, and the last defense against her advances, was gone. His erect cock was out in the open, showing the pent-up need. It was a wonderful view. Both the size and shape would work nicely for the alien's purposes. "There is no ill will between us and humanity. You are but yet another victim of the Forerunners and their schemes." Her hand wrapped around the base of the mast, moving up and down right away. A slow pace, but enough to feel good and keep him ready. "You of all the other humans should know their sins still affect the galaxy and pose a great danger. The Banished are but a tool for me to reach my goals. A necessity born from a lack of other options."

The tempo of her stroking grew faster. Lowering herself to cooperate with mindless beasts made the Harbinger furious, and it was as if she took out her frustrations by pleasuring that shaft. "You have seen them firsthand. Once this is over, peace will not be a possibility. They will eat themselves alive. Humanity, on the other hand, can be reasoned with. Can be…"

Just at that moment the Harbinger noticed the leaking tip of his cock. With a pleased hum, she moved her head close to that bead of pre-cum. John might remain silent, but this was all she needed to know humanity's champion was enjoying this. "… allied with."

Both of them had an incredible need, and the alien couldn't hold out any longer. With a leaking shaft right before her face, when it has been so long since the last time, even someone as mighty as her gave into the pleasure. Her own hand traced down her stomach, while her long slippery tongue moved over the slit, taking care of that drop of arousal. "How does it feel to have someone your species might as well worship doing this to you?" Harbinger said. She didn't expect an answer, not from someone stubborn enough to fight an entire army of the Banished on his own.

With her hand wrapped around the base to hold the erection steady, she then began her fun. Licking at the sensitive head, moving her tongue from the very base to the top. Her work was sloppy, and it took only a moment for the entire cock to be covered in spit. Such a bath wasn't one sided either. The human tasted good. A surprise, but a welcome one. His scent wasn't anything to scoff at either. Her own body responded to having a healthy mate just before her face and she met that arousal head-on with her free hand between her legs.

It was such a shame the time the two had was limited. The AI companion Reclaimer came with was persistent in trying to get through the barrier. This would have to be a taste of what she had to offer and an idea to put into her champion's mind.

Her unusual mouth might not have the lips human women had, but she made up for it with other features and experience. The Harbinger devoured the head of his cock, rolling her tongue around it while eagerly sucking. The organ was quick to release even more of the liquid arousal. Everything he gave, she swallowed while her piercing gaze was looking through his visor. He had to be watching. There was the temptation of letting his armor free to see what the Spartan would do, but that could wait for the next time.

She lowered her mouth further, dropping the eye contact to focus on the task. Besides the long tongue, she could manipulate the insides of her maw well. Tight around John when needed, loose when taking him in. Deeper and deeper, until that head was on the verge of entering her throat.

The chamber was full of the slobbery sounds of her working on Master Chief, but there was no gagging to be heard. The tight seal went even lower until the Harbinger kissed the base of his cock. For the first time, she heard him. A small groan. Easy to miss, but it was there.

The alien traced her hands behind his rump for a good grip and thrust him into her wet mouth, set on hearing her champion again. For a good while, there was nothing. He held out strong, sticking to his silent treatment. Then a throb. More leaking.

Another groan.

The Harbinger only intensified her work, face-fucking herself on his erect shaft. Her spit was running down her chin, and her throat vibrated with the rather unfitting moans. Even if he wasn't pent up, there was no way he could resist such pleasure. The fact he was simply made their fun a little shorter.

With a loud, proper groan the Spartan emptied himself into her hungry maw. White ropes shot down straight into her gullet, while the Harbinger kept her head buried in his crotch. Her mouth and throat were tightly hugging him, milking him and prolonging the orgasm until there was nothing left. Only after there was nothing left did she let go of his cock, giving the tip a last lick.

"We shall see each other again. Consider my offer, so that I may call you my champion," the alien woman said, lowering his body back onto the ground. When his feet made contact, the front of his armor re-appeared good as new.

"C-Chief? Can you hear me?" Weapon finally got through the static. John finally had control of his body back, but before he could do anything about the crimson woman, she already flew away. Only the offer was left.

Could he really say no when the times were this desperate?
