There were too many thoughts spinning through Anakin’s head. The Chancellor- a red blade- Sith- Padme- their child- flashes of heat- fire- death- pain-
A voice, promising life. That of his wife, that of his child. Anakin tried to hold back tears as his feet led him to the Senate building, to the Chancellor’s- the Sith Master’s- office. Already he could feel the Force thrashing about above him, caught in a battle between Light and Dark, and sweat dripped down Anakin’s spine as goosebumps erupted on his arms.
He entered the room, Windu’s purple saber a bright blur in his vision, his figure and that of Palpatine’s even more so. Windu was saying something and Palpatine turned to him, but their words were covered by the sounds of blood rushing in his ears. Anakin swayed on his feet, his mind telling him to pay attention, to intervene, while his instincts hissed at him to run away and hide, to find a dark corner and stay there.
Lightning erupted before him, from Palpatine’s fingers, but Windu caught it on his blade. They were both shouting at him but Anakin could only make out a few words- “I have the power to save the one you love”- and both his heart and mind cried out in agony. A keen was ripped from Anakin’s throat as he thought of her, his wife, his alpha, carrying their children even though the risks were much greater for her than they would have been for him.
“I am too weak… I can’t hold on any longer…” Palpatine was begging, and Anakin barely paid any attention to the words coming out of his throat as he pleaded for Windu not to kill the man before him.
It was useless.
Windu couldn’t be convinced, and Palpatine would die, and Padme would die, and their child would die- “No!” Anakin shouted, snarled, and he wasn’t sure who it was directed at. His lightsaber flashed out of its holder, swung upwards to knock Windu’s saber out of his hands, but he must have misjudged because it chopped them off instead. Anakin had barely a second to feel shocked as Palpatine sprung up to fling lightning at Windu and push him over the edge.
“What have I done,” Anakin whispered to himself, collapsing to the floor. His legs weren’t enough to hold him up anymore, trembling from exertion. He shuddered, from exhaustion or the cold or disgust, he wasn’t sure.
“You are fulfilling your destiny, Anakin,” Palpatine croaked. His face was still blurred but Anakin could see how it had changed, the once-kind visage of his mentor becoming something twisted. Something evil. “Become my apprentice. Learn to use the dark side of the Force.”
Tears burned Anakin’s eyes as he responded. “I will do whatever you ask- just help me save Padme's life. I can't live without her, I won't let her die, I can’t…”
Palpatine laughed, the sound so much more sinister than Anakin had ever heard it. He shuddered, a bead of sweat dripping down his face, as his mentor’s– master’s?– presence seemed to unfold before Anakin’s very eyes and envelop him. “To cheat death is a power only one has achieved, but if we work together, I know we can discover the secret.”
Anakin nodded shakily and shifted into a kneeling position before Palpatine. It took more effort than it should have but Anakin pushed through his weakness. He needed to do this, he needed the power of the Sith and the Dark Side, or his wife and children would be lost to him forever. Anakin’s instinct howled at him at the thought of his mate dying, the oft-forgotten omegan instinct to fight and protect surging within him. Whatever it takes.
“I pledge myself to your teachings. To the ways of the Sith.”
“Good, good,” Palpatine said, one hand coming down to tilt Anakin’s chin up to look him in the eye. Anakin felt a wave of… something travel through him at the contact, leaning into the touch as his eyes started to slide shut. “The Force is strong with you. A powerful Sith you will become. Henceforth, you shall be known as Darth Vader.”
Palpatine’s grip became much stronger at his last few words. A small sound escaped Anakin’s mouth as his eyes flew back open. Palpatine was still staring into his eyes, dark emotions now clouding them, the likes of which Anakin– Vader– had never seen before. Anger, hate, possessiveness, victory… Palpatine’s fingernails began to dig into Vader’s skin as he squeezed even more, gazing on him dispassionately at the pain he was causing.
Vader realized what Palpatine wanted a moment later. “Thank you, my Master,” he said, and Palpatine’s grip loosened immediately. He pulled away and Anakin wanted to follow it and beg for more contact, to bury himself in the older Sith’s scent. He only held back out of the thought of Palpatine glaring at him again, disappointed in his reaction.
“Rise, Darth Vader.”
Vader tried to push himself up, but his legs were far too weak. Every time he tried he collapsed again, until he was a heaving, sweaty mess on the floor. He felt like wading through syrup every time he tried to think, leaving it far easier to give into his baser instincts. Vader shivered against the cold stone as he tried to burrow deeper in his cloaks. He needed warmth, the safety of comfort and familiarity, not this cold, unfeeling place.
“You are no good to my plans like this,” Palpatine said with a sneer. Vader wanted to sob.
“No, master, please,” he begged, thighs clenching to try and relieve some of the aching emptiness growing in his cunt. A wave of understanding washed through him– his heat, weeks ahead of schedule, most likely triggered from the stress of the past few hours. Vader shuddered again and curled up, trying to keep from touching himself. “I can do whatever you ask, master-”
“No, you cannot.” Vader did cry at that, tears slipping down his cheeks. How was he supposed to save Padme from death if he couldn’t even stand? “However, there are ways to stave off such demeaning biological imperatives.”
Vader tilted his head to look up at his master through the tears. With surprising strength Palpatine hauled Anakin up and bent him over his desk. Anakin didn’t resist at all but didn’t help either, leaving Palpating to be the one to ruck up his tunics and pull down his leggings. Vader blushed red as he felt slick stick to his underwear, connecting to his thighs and cunt. He whined and hid his head in his arms, even as he naturally shifted to present.
Palpatine didn’t react besides a derisive snort. He kicked Vader’s legs further apart, leaving the omega to lean more heavily against the desk and push his hips into the edge, and shoved two dry fingers into Vader’s hole.
“Ah-” Vader grunted, the suddenness of stretch painful at first before it warmed into pleasure. He clenched down on the digits and rocked back against them in time with Palpatine’s thrusts, already needing more to fill him.
Almost as if he could hear the thought– and maybe he could, Vader’s shields weren’t at their best currently– Palpatine pulled out his fingers. With a hand on Vader’s lower back keeping him still he couldn’t thrust back to find them again, he only had the pleas falling from his lips.
“Quiet,” Palpatine hissed, digging his fingers into the meat of Vader’s ass nearly hard enough to break the skin. Vader bit his mechno arm instead of moaning at the roush contact, knowing that it would only delay them longer. Still, he couldn’t stop himself from squirming, his heat making him antsy.
Vader nearly dented the metal of his hand, the nerve interface sending the sensation of muted pain back to him, as Palpatine buried his cock in Vader’s hole in one sharp move. He was thicker than Padme though slightly shorter, and Vader keened at the pain of the stretch. His heat had done a lot to loosen his hole and prepare it to be taken, but it didn’t mean that there was no preparation needed either.
Palpatine didn’t give him a moment to adjust either, pulling back out and thrusting in at a rough pace. Vader’s back arched as he was taken, instincts going haywire at the pleasure of finally having a cock in him while recognizing that it wasn’t his mate’s. At one point Vader tried to claw back at Palpatine, either to get him to stop or to urge him on faster, but the sith grabbed Vader’s arm easily and held it behind his back.
Vader could feel his orgasm rising up in him, powerful and all-consuming. He tried resisting for a moment, wishing for the soft and sweet moments with Padme, but Palpatine only grew more insistent. His growing knot rubbed against all the right places within him, making Vader feel shaky and loose and needy.
When Palpatine pushed past Vader’s rim and knotted him he arched his back, eyes rolling toward the ceiling and moaning as he came. Palpatine didn’t stop grinding against Anakin afterwards, his hips rolling in smooth circles that made Vader feel overstimulated. He was too out of it to ask what was happening when Palpatine forced him to stand up, back pressed against Palpatine’s front with a hand placed on his lower stomach. Vader could feel his master manipulating the Force inside him, but to do what he had no idea.
Palpatine let Vader collapse carelessly against the desk when he finished whatever it was he was doing, and they stayed attached for a few more silent minutes. When Palpatine’s knot finally went down Vader had to stop himself from begging for it again, already knowing what that reaction would get him.
“Rise, Darth Vader,” Palpatine said again, repeating his earlier words, and this time, Vader obeyed. He was still shaky on his weak legs but he did, not missing Palpatine’s pleased smirk. Vader rearranged his robes to how they appeared earlier, clenching his teeth and cunt and ignoring the way Palpatine’s come dripped down his thigh as he awaited his master’s orders.
