Chapter Text
Shiro struggled against Sendak’s lackeys, grunting as one of them kicked the back of his knees. He went down, the force from the fall jarring his kneecaps. Still, he tried to pull away, to fight his way out, before a hand grabbed at the nape of his neck.
His body immediately relaxed, but his mind panicked. No one should know about that except for the Paladins. He'd had Allura implant a suppressor into him as soon as it had become obvious what he'd been turned into.
The same hand left his neck and grabbed onto a fistful of his hair, making Shiro look up.
“Sendak.” He growled the name, putting as much venom as he could into that single word.
Sendak laughed, grabbing Shiro’s jaw and tilting it up roughly. He pressed his fingers into the glands on either side of Shiro’s neck, grinning when Shiro melted. Heat burst through Shiro’s whole body, making him whimper and try to press his thighs together to try and stop the slick that he could feel forming between his legs.
“Oh, little omega. You're still so responsive,” Sendak cooed.
A torrent of memories tore through him, and he gasped, eyes going unfocused.
It was Sendak. It had all been Sendak. He'd been the one who’d taken Shiro, who had given him to the Druids to be experimented on, who had taken Shiro as a new omega. He could remember vividly how it felt to be under Sendak, the bigger Galra pressing into him, knotting him, making him beg and cry and moan.
“You did this to me.”
“Oh you're so right, my little omega. And now that I have you back, you're not going anywhere.”
Sendak's eyes shifted to Lance, face morphing into an expression of hunger. “And it looks like I'm getting a second omega too. Oh, how lucky for me.”
Shiro’s chest clenched. Not Lance. He struggled some more, renewed with energy. He had to protect Lance.
It didn't last long, though, because Sendak let him go, marching over to Lance’s prone body and placing a single clawed hand on his neck.
“Keep struggling and you'll get to see how this one looks as he's gasping his dying breath.”
Sendak lifted Lance off the ground as soon as Shiro stopped struggling, throwing him over his shoulder.
“You,” he pointed at a random drone and tossed it a communication device, “stay here. When I give the order, shut down the particle barrier. The rest of you, come with me.”
Sendak’s goons pulled Shiro up onto his feet, and Sendak walked calmly up to look over him.
“You're going to take us to the Black Lion, and you're going to get in it and take us wherever I tell you. You can say no if you truly don't want to, but if you don't, I'll make you watch as I devour this pretty little soon to be omega dry, and then I'll rip him open so you can hold him as he dies. Sound good?”
Shiro gulped, eyes on Lance’s prone form. “Okay. I'll take you.”
Under Shiro’s direction, they arrived at the hangar for the Black Lion quickly. Sendak grinned up at the sight of the Black Lion, large and majestic. Shiro knew without a doubt that it would be Sendak’s absolute delight to hand Black over to Zarkon, and with Black in Zarkon’s possession, Voltron would belong to the Galra in no time. There would be no stopping them.
He hoped with everything he had in him that Black would listen to him.
She let them all in, and Shiro could feel her discontent with the fact that some of Zarkon’s Galra were polluting her. Shiro ran his hand lovingly against her console, murmuring words on endearment to her.
Sendak settled himself behind Shiro, hands lightly grazing Shiro’s neck, and Shiro shivered. He let himself fall into their bond, eyes closed as he begged for Black to start up. She resisted, pushing back against him, until he reminded her that it was them or the Castle.
Finally, she relented, turning on and walking towards the closed hangar. Shiro vaguely heard Sendak order the drone he'd left behind to lower the particle barrier, and as it did, the hangar door opened.
Shiro led Black out easily, conversing with her silently, letting her in on the plan forming in his head. She didn't like it, he could tell. She hated it. But, she also conceded that it was their best option at this point. They were the leaders of their Prides, and they had to do what was best for the ones they cared for.
Sendak whispered in his ear as they flew away from the Castle, whispering directions in between threats and promises. Shiro shuddered, remembering just how insatiable Sendak had been before. No doubt it would be worse. As he drove, he promised to himself that he would do everything in his power to make sure that Sendak wouldn’t hurt Lance too much. He’d do anything that was asked of him if it meant keeping Lance safe.
Black rumbled in his head, both proud and worried. She gently reminded him that she wouldn’t be there to take care of him, and that he was going to need to make sure to keep the both of them safe until she could go back for him. He sent back reassurance. He wouldn’t do anything stupid, he promised. Black wasn’t shy in letting him know that he’d better not.
He smiled, running his hand along her console again. He would miss her so much. Still, she reminded him that she was never far.
All too soon, he could see a Galra ship. First, just a speck in the distance. Then, as they got closer, towering over them. Even though the ship seemed small compared to other Galra ships they’d seen, it was still considerably larger than Black. Still, the fact that it was smaller and likely had less troops gave them a slight advantage in their plan.
They docked, and the Galra on the ship wasted no time in tying Black down as Sendak’s right hand man dragged Shiro out with the rest of them. Something held him, though, and Black’s resounding roar made everyone pause.
“Please, let me say goodbye,” Shiro begged Sendak.
Sendak watched curiously, then motioned for Haxus to let Shiro get closer. “Fine. You know what will happen if something goes wrong.”
Shiro nodded, pulling himself out of Haxus’s grip and walking up to Black. He stared up at her, and as he watched, she leaned her head down, pressing her large forehead against him. He hugged her as best as he could, and he felt the sorrow emanate off of her, a silent apology for what she was leaving him to. He assured her that he knew what he was doing, that he would protect Lance with his life, and that the sooner she and Blue found new Paladins, the sooner she could come save him.
He pulled away, her determination ringing through him, and he followed Sendak willingly, leaving the hangar where they’d docked.
Strangely enough, Sendak didn’t keep them on the ship for very long, instead leaving most of his crew, except for Haxus, and leading them all to the personal ships. They all clambered into the hatch, where Haxus took the reins and sped the ship away.
Sendak set Lance down haphazardly on one of the seats, before turning towards Shiro with a predatory glance. Shiro gulped, backing away from him. He backed himself up into the wall, and with Sendak still approaching, he started up at the Galra, eyes defiant. He’d almost given himself up completely last time, he remembered. Sendak had taken him so often, taken so much from him. His eyes flicked over to Lance briefly. Now he had Lance, though. He’d teach him to survive, how to navigate Sendak, but he wouldn’t let either of them lose.
Still, that didn’t stop the shiver of disgust that wracked through his body as Sendak leaned down to kiss and nibble at the glands on the sides of his neck. He closed his eyes, tense as his body betrayed him, leaking slick, although thankfully not as much as if he hadn’t had the implant. He silently thanked the heavens for Altean technology as Sendak pulled him closer, removing his shirt and biting down hard enough on Shiro’s neck to almost break the skin. Shiro gasped loudly, trying to pull away from Sendak.
Sendak tsked at him, shaking his head. “That’s not allowed. You know that.”
He did know that. It was one of their first rules. He took anything and everything Sendak gave him. Refusing wasn’t allowed, because this wasn’t about Shiro’s pleasure. It was about Sendak’s. Still, he felt wrong, he felt used, and he shut his eyes and Sendak went back to marking him up.
Maybe, just maybe, if he closed his eyes and let his mind wander, it’d be easier.
Somehow, his mind found Black, and Black made a sorrowful noise in his head. He could feel her anger, her helplessness, and he could feel her break free. She had no problem causing destruction in her wake, away from the ship, and he couldn’t help but smile softly, even as Sendak shoved a hand down his pants.
“Sir,” Haxus cut in.
Sendak stopped feeling Shiro up to look at Haxus impatiently. “This had better be damn important, Haxus.”
“The Black Lion has escaped.”
Sendak’s head snapped to Shiro, who was still smiling softly. Sendak’s face was curious, and Shiro met it unflinchingly.
“Oh, you’re a sneaky one, aren’t you?” Sendak chuckled darkly. “Oh well. I won anyways. The fools on that ship are the ones who will pay for losing the Lion. Not me.”
Shiro shrugged.
Sendak chuckled again. “Oh, I’ve missed you, my feisty omega.”
He picked Shiro up, slamming him up against the wall and scenting his way up Shiro’s neck. Shiro whimpered against his will, turning his head away. He felt Sendak smile against his skin, and this time the bite did make it through Shiro’s skin. Shiro made a soft noise of pain, tears welling up in his eyes behind his eyelids.
Sendak made it a point to keep getting Shiro wet, until even with the implant his pants were soaked. Once it got to that point, Sendak let Shiro down onto the ground, pulling him onto his knees as he sat down in the ship.
“You know what I want, omega.”
Shiro set to it immediately, opening up Sendak’s pants and stroking him to full hardness. Sendak growled in pleasure, little praises escaping his mouth and making Shiro’s omega brain sigh with happiness. Pleasing an Alpha always made it do that. Sendak ran a hand through Shiro’s hair, tugging on it slightly, and Shiro went down easily enough, opening his mouth and taking Sendak’s cock into his mouth.
He swallowed down as much as he could, the heavy weight of it resting against his tongue. Shiro looked up at Sendak from underneath his lashes, mouth working softly against the skin of his cock.
“Not now, omega. I’ll knot your mouth later. Right now, just stay there.”
Shiro acquiesced. He remembered how much Sendak had liked it when he would warm his cock. It only made sense that that’s what he would have done right now.
Sendak and Haxus didn’t speak of anything substantial for the ride, although to be entirely honest, Shiro was focusing most of his attention on staying where he was and not upsetting Sendak, so he couldn’t be entirely certain. He was silently thankful that Lance stayed knocked out for the entire shuttle ride, although it was also worrying that he was so out of it.
By the time they reached the main ship, Sendak had almost gone flaccid at least three times, and Shiro had had to work him back to hardness each time. It was exhausting, and his jaw and tongue had actually started to go numb by the time the ship docked.
When Haxus gave Sendak the appropriate warning, Sendak eased his cock out of Shiro’s mouth, pumping it only a few times before coming all over Shiro’s face. Shiro flinched, disgusted at the feeling, before Sendak rubbed it thoroughly into his face, so that any Galra who smelled him would know who he belonged to.
“Grab him, Haxus.”
While Sendak tossed a still unconscious Lance over his shoulder, Haxus grabbed onto Shiro. Shiro could feel him lean in and sniff Shiro deeply, obviously enjoying the smell of turned on omega. It made him shift uncomfortably, and Sendak just laughed.
“One day, Haxus. Work hard, and then you might get your own omega some day.”
“I sure do hope so, sir. He smells absolutely delicious.”
“He’s as delicious as he smells. More so even.”
Haxus growled in his ear, and Shiro jerked, looking at Sendak questioningly. Sendak was still possessive, right? He wouldn’t… share them, would he?
“Careful, Haxus,” Sendak warned. “I’m not the sharing type.”
Shiro deflated in relief, just as Haxus did in disappointment. They followed Sendak from the ship, Haxus and Sendak nodding to the Galra who all stopped to stare at the very turned on and very claimed omega. Shiro could see the hunger in every single one of their eyes, and he was so happy that he wouldn’t have to worry about being given to any of them.
A Druid met them in the hangar and led them to a room, ushering them all in. The Druid left without another word, and Sendak sat down, setting Lance down while Haxus held onto Shiro. They didn’t wait long before Haggar herself walked into the room, stopping short when she saw Shiro and Lance, both in their Paladin armor.
“Ah, the Black and Blue Paladins. I assume this means that you also have their Lions?”
Sendak crossed his arms, leaning back. “I was successful in getting the Black Lion, and I left it at Outpost 5TH-6. However, it seems that the Black Lion was too strong for them, because we hadn’t even been gone for long when we received news that the Lion had escaped them.”
Haggar stared piercingly at Sendak and Shiro, searching both of their expressions, before nodding. “Then they will be dealt with for losing such a precious piece of technology. You, however, succeeded.” Her eyes fell on Lance. “I assume you want my Druids to turn this one into an omega as well?”
Sendak nodded, before nodding at Shiro. “If you could also look him over, I believe the Alteans tampered with your creation. He doesn’t respond in the same ways anymore.”
Shiro stiffened. So Sendak had noticed. He gulped. The last thing he wanted was for his implant to be taken from him. Then there would be nothing keeping him from getting pregnant.
Haggar smiled menacingly. “Based on his reaction, I would assume that he has been tampered with, yes. No worries, my Druids will have him fixed up in no time. Would you like anything else?”
Sendak tilted his chin towards Haxus. “Haxus was instrumental in securing the Black Lion. I feel he should be given recompense of some sort.”
Haggar nodded, sweeping out of the room. A few Druids swarmed into the room after her, one grabbing Lance, one grabbing Shiro, and the other leading a stunned Haxus out.
“They will be delivered to your quarters when we are done with them,” the Druid at Shiro’s side informed Sendak, who nodded.
“Vrepit sa.”
“Vrepit sa,” came the chorus of replies.
As the Druid led Shiro out, he heard a soft, “This will make everything easier for us,” before he felt a pinch in his neck. His eyes rolled back as he felt his body give way and his vision went black.
…
“Shiro? Shiro! Wake up please !”
Shiro groaned, feeling like his brain was rebooting. He felt tired, heavy, thirsty. He didn’t know what was going on.
Then he registered the voice and the panic in it, and his eyes snapped open. He sat up quickly, grabbing his head as the sudden movement made the room spin, and looked over to his side where Lance was sitting, wide eyed and obviously panicking.
He reached out slowly, grabbing Lance’s arm and getting his attention.
Lance’s head snapped up to meet his eyes, and Shiro could see the fear as he tried to figure out what was going on. “Shiro? What’s happening? Where are we?”
Shiro shifted more towards Lance, shushing him softly. “Let’s start from the beginning. What do you remember last?”
“Umm.” Lance groaned, grabbing his head and closing his eyes. “I remember seeing Rover coming into the room with the crystal, then an exploding noise and a bright light.”
He gasped. “Did the crystal of the Castle get blown up?”
Shiro nodded, placing his hands on Lance’s shoulders. “Come on, Lance. I need you to breathe with me. I won’t be able to fill you in in time if you’re panicking.”
“On time? Shiro, what do you mean in time? Is something going to happen?”
Lance’s voice was getting progressively more panicked. Shiro could understand. He’d been in much the same state when the Druids had just finished turning him.
Still, they didn’t have time.
“Not now, Lance. Deep breaths,” he reminded.
Lance nodded, following Shiro’s breathing, and Shiro ran a comforting hand through Lance’s hair.
“Okay. So here’s what happened. The Galra blew up the crystal that ran the Castle. You were pretty badly injured and unconscious. Hunk and Coran went to go get a new crystal, and Keith and Allura went to go help the Arusians who were being attacked. But it was all a diversion, and while you, me, and Pidge were in the Castle, Sendak and his remaining crew took over the Castle.”
Lance made a small noise of surprise, but stayed calm at Shiro’s glance, nodding. “What happened then?”
“I don’t know what happened to Pidge. She didn’t get spotted by the Galra, I don’t think. But we both got captured, and Sendak made me take them to Black. I had her take us to one of the Galra outpost ships, and then Sendak got us on a ship to transfer us here, to Zarkon’s main ship. While we were on our way, Black escaped. She going to go back to the Castle, she’s going to help them find us.”
“We’re on Zarkon’s main ship?”
Lance’s voice was small, scared, and Shiro’s heart ached for him.
He nodded. “Only temporarily. Sendak is still needed out on the front, so we’ll only be here until he gets a new ship. Then we’ll be transferred to that one with him.”
Lance was quiet, and Shiro rubbed his arm comfortingly, knowing that it was a lot to process. “I’m guessing that us getting transferred with him has to do with why I feel really funny and why we’re both dressed like strippers?”
Shiro bit his lip and then nodded very slowly.
“I didn’t remember this until Sendak took the Castle, but I was given to Sendak as a gift for some planet he conquered or something like that. I can’t remember. But the important part is that the Druids experimented on me and made me an omega. That’s why I went into heat that one time while we were at the Castle. It wasn’t that I’d always been an omega and my suppressants had finally worn off. It was that I hadn’t been an omega before Kerberos, and after Sendak, I was.”
Lance made a broken sound. “Is that…?”
Shiro nodded again, face apologetic. “Sendak asked Haggar to have the Druids change you too. You’re an omega now. Right now, we’re pretty much Sendak’s sex slaves.”
The tears in Lance’s eyes broke Shiro’s heart. He leaned forward, wiping his tears away with one hand and reaching out with his other to hold Lance’s hand.
“I know,” he whispered. “It’s terrifying. But I’ll walk you through it. It’s not going to be easy by any stretch of the imagination, but I remember what he likes. I’ll help you.”
“I don’t wanna do this, Shiro,” Lance cried softly. “I don’t know if I can.”
“I know. I know. It’s okay to cry, Lance. I’m here.”
Lance threw himself into Shiro’s arms, crying softly into his chest. Even now, freaking out the way he was, Shiro could tell that he was trying to keep himself quiet in case Sendak was nearby. Shiro shifted Lance to make him more comfortable, when Lance let out a tiny moan. Shiro pulled away a little bit, and Lance looked very confused, reaching back and feeling around, before his eyes widened in terror.
Shiro knew then that Lance had found the plug where it was nestled between his cheeks. Shiro himself had felt it as soon as he’d sat up. Sendak was partial to them because they meant that he’d be ready and open any time Sendak pleased. He pulled Lance in again, shushing him as his sobs got stronger.
He was only able to comfort Lance for a little longer when the door opened and Sendak strode in.
“Do what I do,” he whispered in Lance’s ear. “You can do this.”
Without another word, Shiro crawled off the bed they’d both been placed on, crawling up to Sendak and kneeling in front of him. He could feel and hear Lance timidly doing the same, and he prayed silently that Lance would be okay.
“Oh,” Sendak cooed sarcastically. “It seems one of my beautiful little omegas has been crying.”
He leaned down, cupping Lance’s face, and Shiro could see Lance holding his breath, not sure what to do. Sendak pulled Lance up a little by his jaw, making Lance grunt softly in pain, before licking away the tears that were still running down Lance’s face and dropping him.
“Are you unhappy, omega? Am I not enough for you?”
Lance looked at Shiro, obviously panicked, and Shiro shook his head slightly enough that he hoped Sendak didn’t catch it.
“O-of course you’re enough,” Lance whispered softly, voice shaky.
“I’m enough, what?”
Shiro could see Lance struggling with the words, having gone through life as a beta never thinking he’d have to say it.
“Of course you’re enough…” He hesitated again. “...Alpha.”
“So you are teachable, little omega. Good. I was concerned that I would have to toss you out as a plaything for my underlings.”
Lance whimpered, and Sendak turned to Shiro.
“Do you enjoy being back with me, omega?”
Shiro nodded, leaning in to nuzzle at Sendak’s thighs. “I’ve missed you, Alpha.”
“Very good, omega. Now, don’t you think that crying has spoiled the mood a little bit?”
Shiro bit his lip, opening and closing his mouth. Disagreeing with Sendak was bad, but he also didn’t want to throw Lance under the bus.
“Remember, omega, you’re my favorite, so I won’t hurt you too much. This little one here though, he still needs to be broken in. And I think that giving your punishments to him when you disobey will do a spectacular job of speeding up that process, don’t you?”
Shiro’s mouth opened and closed a few more times, and he looked over at Lance. He closed his eyes and looked down, unable to look at Lance. He knew that this was betrayal, but he would rather betray Lance and keep him a little bit safer than stay loyal and cause him unnecessary hurt.
“You’re right, Alpha.”
He clearly heard Lance’s intake of breath, and he screwed his eyes shut even tighter. There was no way to win this, he reminded himself. Black was going back to the Castle. She would be there. She would get new Paladins, and she would help them. She would bring them help and rescue. But until then, they needed to survive. Survival meant hard decisions.
Sendak made a pleased noise above him.
“Do you think I should give him a reason to cry, omega?”
Shiro’s heart ached, a physical pain that took his breath away. God, he hoped Lance could forgive him.
“Yes, Alpha.”
No sooner than Shiro had whispered those words, he heard a loud slap crack in his ears. His eyes shot open, and he saw Lance on the ground, clutching his face. Sendak moved to loom above Lance, who scurried back, propping himself on his elbows and using them in tandem with his legs to move away.
Shiro watched in slow motion as Sendak leaned down, grabbing Lance’s leg and pulling him hard enough that Lance’s arms gave out under him, letting his head fall with a loud thunk as it hit the ground. Lance looked confused, scared, hurt, those emotions magnifying on his face as Sendak straddled him on the ground.
“Please, Alpha,” Lance begged, tears beginning anew as Sendak’s metal hand grasped at his throat. He gasped, face turning red as pressure was applied and he began to lose the ability to breathe.
Shiro whined, soft and high in the back of his throat, crawling over to Sendak. This way, in this moment, he was scared that Sendak might actually kill Lance.
Reaching out with a shaking hand, he touched Sendak’s flesh and blood arm, leaning up to scent him. Sendak’s head immediately snapped towards him, hand loosening on Lance’s neck, who immediately began softly begging for mercy.
“Alpha,” Shiro murmured demurely. “You don’t want to dispose of your new omega so soon after you’ve gotten him. Take me instead. Fuck me, fill me with your seed. Breed me, Alpha, and let him go for tonight.”
Sendak licked his lips, letting go of Lance to grab Shiro’s jaw roughly. Shiro winced slightly, but let Sendak press the sides of his mouth to open it. He obediently sucked on the fingers Sendak shoved into his mouth, tongue caressing his skin and fur and claws.
Sendak growled, pleased, and pulled his fingers out to rub them down Shiro’s neck.
“Get on the bed,” he ordered. “Present yourself.”
Shiro obeyed, shucking off the little clothes that he had on as he made his way up to the bed. He kneeled on the mattress, lowering his face into the sheets as he brought his hands back to hold himself open.
He could hear Lance catching his breath, coughing and wheezing, in the corner, as Sendak got up. Shiro felt and heard his heavy footsteps as Sendak approached the bed. Just like before when he'd been Sendak’s plaything, he imagined a faceless Alpha, one who was kind and good and teased him in the right ways to make him gush.
Sendak purred as he placed a hand on the small of Shiro’s back, leaning down to bite his shoulder blade. The skin broke easily under his teeth, and Sendak lapped up the first wellings of the blood.
Shiro whimpered into the sheets, opening his mouth to get some more air and tilting his head to the side. He saw Lance, staring at him with wide eyes, bruises already bloomed on his delicate throat. Lance looked scared, and Shiro wanted so bad to comfort him.
Instead, he gasped as Sendak pulled out the plug. He could feel his slick dripping down his thighs, thick and clear. His eyes scrunched shut in disgust as Sendak licked it all up, purring into his skin. Still, as soon as Sendak’s tongue pressed against his hole, he forced himself to moan, to press back and act like he wanted it.
Sendak swatted Shiro’s hands away, holding him open himself, and Shiro brought his hands up to either side of his head, clenching and unclenching the sheets rhythmically.
“Oh, Alpha,” he gasped, arching his back beautifully. “ Yes . Thank you, Alpha. You make me feel so good.”
He babbled as Sendak kept eating him out, rolling his body up and pushing back onto his face. Sendak, for his part, was spurred on by the pleas, getting more enthusiastic until, even with the disgust Shiro was feeling, he was close to coming.
He gasped loudly, pushing himself up just a little. “Alpha, please. I'm gonna come. I want you to come first.”
Sendak pulled away, grabbing Shiro’s hair and tugging on it so Shiro’s back was curved tightly, almost pressing him in half. Sendak breathed heavily against Shiro’s ear, nibbling on his earlobe. “Do you want me to knot you, omega?”
Shiro moaned brokenly, licking his chapped lips and nodding as best as he could. “Please, Alpha. Split me open on your knot. Tie me to your bed and keep me all plugged up, open and ready for your cock all the time.”
“Oh, you're so tempting, my sweet little omega,” Sendak purred, pressing his hand against Shiro’s neck and dragging his claws lightly against the skin there.
“I have to admit, as lovely as you look split open on my knot, you took me away from my other omega before I got my fill of squeezing a pretty little neck. Can I do yours? Cut off your air while I fuck you and make you beg for my knot?”
Shiro swallowed hard, and he knew Sendak could feel it because the Galra chuckled darkly into his ear. “I can always go back to what I was doing before and then come knot you afterwards anyways.”
Shiro shook his head. “No, Alpha. I'm here for you. Whatever you want to do to me, you can.”
“Good.”
Shiro found himself being flipped over, legs hooked over Sendak’s shoulders. He felt the press of Sendak’s cock against his hole and he forced himself to relax. It was the only way he wouldn't feel like he was getting torn in two.
Sendak bottomed out in one quick movement, punching Shiro’s breath out of him. He wasted no time in pounding into him, chasing his own pleasure. Shiro moaned and whimpered and begged for more the way that Sendak expected from him.
Soon, Sendak’s warm hand pressed against his neck, putting pressure and slowly cutting off his air. Shiro gasped, trying to keep his breathing even, though it was hard with the way Sendak was fucking into him. The pressure increased gradually, until he was scrabbling at Sendak’s hand with his own, mouth opening and closing as he gasped for air that wasn't coming.
Sendak's face above his was pleased, taking joy in his fear, before letting go just enough to let him catch his breath. He gasped and coughed, whimpering. Still, he knew what was expected of him. “Please, Alpha. More.”
The cycle repeated, with Sendak cutting off his air slowly, only to let him breathe just long enough to beg for more. Each time his air cut off, his whole body tensed, and he could tell it brought more pleasure to Sendak, whose thrusts would become harder, deeper, rougher.
Eventually, he felt Sendak’s knot forming, pushing at the rim of his hole with every thrust until, with one solid push, it popped into him, locking them together. Shiro could tell that Sendak was close to coming, when suddenly, with no build up, all his air was cut off. He jerked in surprise, struggling under Sendak’s grip. Sendak, for his part, kept grinding softly into Shiro’s body, pushing himself closer and closer to coming.
Black spots started forming around Shiro’s vision, and his struggles got progressively weaker. Shiro was legitimately scared that he was going to pass out when, thankfully, Sendak finally came. He could feel Sendak’s knot pulsing, filling him with come. The hand around his throat pulled away, and Shiro coughed and wheezed, pulling precious air back into his lungs.
Sendak stayed there propped up above Shiro until his knot receded, biting and kissing all over Shiro’s skin until more skin was bruised and mottled than not.
No sooner than he had pulled out, Sendak grabbed the plug he had abandoned on the bed, rolling it in the slick and come that were leaking out of Shiro before pressing it in. Pleased with his work, Sendak got up off the bed and started fixing up his clothes, cleaning himself up to look presentable.
“I'm needed at a meeting soon,” he informed Shiro. “Clean the other one up. And make sure he knows what's expected of him. He won't last long otherwise.”
“Yes, Alpha.”
Shiro watched as Sendak left, and as soon as the door closed behind him, he bolted to Lance.
