“I will give you an heir, and in return you will spare all remaining Asgardians.”
Thor would need Heimdall in the upcoming battle, and Valkyrie and Korg should be a safe distance away from the Statesman and Sanctuary II in the escape pods, filled with as many Asgardian refugees as that they had managed to bring along before the Black Order had boarded them. He hated the very thought of willingly put himself through what was to come, but their people needed to live.
Their people. Loki would always see himself as one of them, despite being something else entirely. Something which ironcially enough could save Thor and Heimdall’s lives.
Thanos mulled over Loki’s request for a moment. His intention had never been to wipe out the entire race, as easy as it should be considering they no longer had a home world of their own, but he supposed the few that still remained could be given the chance to settle somewhere. He’d just wipe out even more of whatever race they had to share resources with. An heir of his own was defintiely worth that, with his own race of Titans being almost extinct. A child combined of his own strength and Loki’s sorcery would undoubtedly become a worthy successor.
Thanos grinned, wide and dangerously.
“It seems we’ve finally reached an understanding,” he said and reached out his large hand to stroke Loki’s body, anticipating how it would grow with his seed inside it.
“Loki?!” Thor yelled from where he was being held by the heavy metal shackles Maw had telekinetically put on him. “Don’t do this…!”
Loki looked back at him.
“I assure you brother, the sun will shine on us again,” he said with a weak smile before turning back to Thanos. “Shall we depart for your ship, then?”
“I’d find it more interesting to consummate our union here,” Thanos said, making Loki’s heart grow cold. “To have my Children see their brother or sister being concieved. And after all, should your noble sacrifice not be witnessed by the people you’re trying so desperately to save?”
“I’d much rather not,” Loki bit out through clenched teeth but Thanos had already made up his mind.
The Titan sat down on the steps leading up to the platform where Thor’s throne had once stood. He motioned for Loki to come over and he forced himself to obey. He could hear Heimdall’s rattling breaths as he passed his body, fearing that his end would come before Thor could get him the help needed.
“Strip.”
Loki slowly removed his clothes, dropping them in a heap on the floor. He could hear Thor’s sob as he watched the large wounds on Loki’s back and chest where he’d been stabbed by Kurse, something which even Loki himself at the time had believed had been enough to kill him. Thanos stroked the wound on his chest, knowing the fatality of such things on any lesser beings.
“You weren’t much of a fighter or conquerer but you’re strong and resiliant in your own way. Our child will be a force to be reckoned with. Prepare yourself, sorcerer.”
Loki kept his eyes steady on Thanos as he shifted into a female form. He could only grow slightly bigger to aid himself with taking Thanos’ length, anything more would only be an illusion and wouldn’t make a difference for himself at all.
Thanos tutted as he shook his head.
“Even as beautiful as you look in this form, I want you.”
Loki blinked.
“I, I’m not–“
“We both know you don’t have to be in a female form to get pregnant. It’ll bring me more pleasure to see you as I know you Loki, not this new form of yours.”
It’d be easier for Thanos to be rough on him with the form he was already familiar with than with an unknown woman.
Loki hesitated before he changed back into his male form. He contemplated changing into his Jötun skin but this would be difficult enough for himself without having Thor witness it for the first time in these conditions.
Thanos patted his knee and Loki moved to sit astride the large thigh, accepting Thanos touches and kisses and trying to ignore the sounds of Thor struggling to get free to save him, his shouts for them to stop.
A thick finger prodded his entrance and Loki murmured a spell to slicken himself up and loosen his muscles even more as the finger kept jabbing into him. It was large and uncomfortable inside of him and he broke away from Thanos kiss.
“Open up for me, little one,” Thanos growled as he tried to insert another finger.
Loki panted harshly from the pain already and started doubting himself. He knew he could take someone of a large size, to get pregnant. And during his years posing as Odin he’d studied more about Jötnar and their biology as his head had still brimmed with the thoughts of Thanos’ first offer to him, to have Loki carry his offspring in exchange for a seat by his side, and learned that even runts like Loki could get mated by giants far larger than themselves. He should be able to take Thanos. He needed to. Once it had happened, Thor and Heimdall and the others would be saved.
He used all the spells he could think of to make it easier for himself, and soon three fingers slid into him without resistance, preparing him for something much bigger.
Thanos used his other hand to open up his trousers and take his erect dick out. Loki took one look at the dark purple head and turned away with a shudder.
“Go ahead and touch it. Get yourself acquainted with it.”
Loki took a deep breath before he reached out a hand to feel the soft skin, wet already from the pre-cum. Thanos was incredibly large. Loki didn’t think even both his hands would be enough to completely wrap around the girth of it.
Thanos hummed appreciatevly at Loki’s weak attempts at stroking him and he shoved the three fingers harder inside of him, which almost made Loki fall down from where he sat astride Thanos’ thigh and he had to reach out to grab a hold on Thanos to keep his balance.
“Are you ready for me, Asgardian?”
No.
Definitely not.
He never would be.
Despite his own rising panic, he nodded his head.
Thanos removed his fingers.
“Turn around.”
Loki shifted in his seat, to sit astride Thanos’ leg with his back against the Titan’s chest. He kept his eyes closed to not look at the carnage around them. Having to listen to Thor call for him was hard enough.
Thanos suddenly grabbed him by the neck and Loki’s eyes opened wide as he gasped for air. His hands came up to try and pry Thanos’ large hand away from him but he was no match for the Titan. Thanos lifted him by the neck and positioned him over his cock. The other hand, still inside the fearsome Gauntlet, grabbed a hold of Loki’s thigh to lift it and spread it to help open him up.
And then he pushed Loki down, down, until the head of his cock was forced inside. Loki would’ve cried out in pain if he had enough air to do so. Thanos kept choking him, making the blood that was unable to go up to his head fill out his dick instead, making it harden.
Once it was erect, Thanos eased up on his hold with a laugh.
“I though it would be a shame if you weren’t enjoying our union as well,” he chuckled as he remained still inside of Loki, who was too busy coughing and gasping for air to do anything else.
Once Loki had regained his breath, Thanos gently pushed up into him with small thrusts until half of him was inside.
“You’re extraordinary, little godling. I knew you would be.”
He lifted Loki’s leg higher to make sure their audience would get a good look of where they connected.
“Touch yourself, Loki. Take as much pleasure from this as I’m taking from you.” He nuzzled the back of Loki’s head and huffed out a breath. “It’ll be good for the concieving.”
Loki wrapped a hand around himself, but his stroking only kept himself hard as he didn’t recieve any pleasure that could overtake the pain of being penetrated by something so incredibly big that even made his belly bulge slightly.
Thanos used his grip on Loki’s leg and neck to move him up and down. Loki placed his free foot on Thanos’ thigh to aid himself in the movement and to not have all of his considerate weight dangling from his neck.
Thanos leaned down over him and Loki turned his head as much as he was able to, to accept his kisses. He still kept stroking himself, made a few tricks of adding vibrations to his touches, anything to make it easier on himself, to not break apart in front of Thor. Eventually the pleasure started to reach through to him and he moaned into Thanos’ mouth as he forced himself closer to a climax to please Thanos.
The Titan increased the speed and ferocity of his thrusts and Loki broke the kiss to gasp for air as Thanos kept fucking him harder and harder.
“Wait, stop…”
The hold around his neck tightened and he once again found himself trying grab onto Thanos’ hand to get it off and be able to breathe. Thanos held him tighter than before and Loki was almost certain his neck would snap at any moment.
A sudden spasm ran through him and before he even realised what had happened, his body forced out an ejaculation. Thanos chuckled lightly as he slowly eased his hold on Loki’s neck, letting him suck in a breath of air.
“So you did find it pleasurable,” he groaned as he fucked into the hole that had tightened with Loki’s climax. “Keep squeezing me like that, I’m almost there myself.”
Loki’s body already did so on its own accord without him being aware of it, his Jötun instincts wanting to milk every last drop greedily into himself as he’d reached his peak. Thanos suddenly changed his hold, the hand around his neck had now moved down to encircle Loki’s entire waist, making Loki flop back against Thanos like a ragdoll as Thanos used his new hold to move Loki up and down in sync with his almost brutal thrusts.
Thanos came with a guttural groan, holding Loki steadfast as he pushed in as far as he could go as he filled him up. Loki bit his lip to try and stop a whine escape from him as he felt his body repeatedly squeeze around the Titan, trying to take all it could get from him into himself.
