Chapter Text
William's back hit the sparring floor, hard.
With a grunt, he tried rolling on his side to get up, but Mark punched his sternum and pinned him down with only his fist on his chest. "You're dead," He stated, staring down at William.
He speaks up, never leaving William's gaze but averting his attention to the other humans in the crowd who are next to be sparring with him. "If you don't want your whole lives to be spent in someone's cage as a slave, you need to be strong enough to last against a viltrumite for more than 7 seconds." Finally, he released William, standing straight and looking to his students. "This human didn't last 2. Making him the quickest to die. If you don't want to be like him and forced into servitude, then I suggest you all take soldier training seriously."
Mark tried not to look down when he heard William groan in pain when he stumbled getting up. Once William stood up, he quickly grabbed his arm. "Don't leave once training is over, because your training isn't over."
Weakly, William nodded. "Yes, sir."
Mark shoved him away, turning to the next in the group. "Next!"
When William walked to the sideling, he tried his best to hide his smile.

Kiss. "'Mark," Kiss. "Mark, let me breath!" William laughed as Mark showered his face in kisses. Williams against the wall in a secluded park of the training gym, cornered by Mark.
"I'm sorry, it's just-" He keeps pressing his lips into his jaw up to his eyes. "I'm sorry for being rough today in training." He presses one firm kiss on his lips.
"You don't have to apologize, I get it." William kisses him back. "You have to sell it. Aaaand it would be embarrassing if I managed to beat up to Viltrum Empires soon to be emperor." he jokes while flexing his lean arms.
Mark smiles down on him, bringing his hand up to hold his face and kisses him deeply. "I just wish I could keep you safe, not have to play these charades."
"Hey, when I go up for auction since I can't cut it as a soldier, then we can be ourselves. No charades, no worrying about if I might get beaten by a viltrumite for being funny." Mark frowns. "You can protect me, it's fucked up that we have to do it like this but, it's the best way you can keep me safe.
Mark's frown doesn't go away, but he does reach to hold William's hand. He brings his hand up and kisses his palm. "I wish I could take you away."
In this empire, where he killed his dad but couldn't defeat the viltrumites, he had to surrender in order to keep his loved ones from being killed. In the end, when the empire touched down on Earth, they took every human they didn't kill into custody. William is only alive because they figured implementing a program to train them would be useful to sort from who they could make soldiers in their fodder army or as slaves. Most of whom may end up just as target practice for viltrumites who want to get a kick out of playing with their kills.
His mom was already dead, Amber was killed in the streets when she fought against the viltrumites as a resistance member. Eve died along with the other guardians. William was the only one who managed to squirm his way to survival. His only link to humanity and the only one who he could trust to love him for who he is, not what he is.
Now Mark only wished buying him wasn't the only way he could keep him from being killed for being weak. It's the only way he can get away with keeping William out of the camps, out of the army, and into a space he carved out just for the two of them.
"Well, you have me now." William wraps his arms around Marks neck and leans up to bring his face up to his. "I need some training done, remember? So, what was the great, oh mighty Mark Grayson have in store for lil ol human me?"
Mark hums, pretending to think. He places his hands on Williams hips and rubs circles in his sides with his thumbs. "I'm thinking, back in training. Your endurance was... lackluster." William was quick to tsk, but was quick to get quite when Mark tugged the waistline of his white uniform down and off, leaving only the white skirt part of his uniform to cover. "Also, your legs," Mark picks him up, holds him against the wall, and lifts his legs up to fold them, making his knees almost touch his shoulders. "I think some flexibility might help in your ability to run."
"Oh please," William tries to keep his cool, hard to do so when his face is as flushed as it is. "I know you get off on the chase. I can practically feel your hard on when you catch me."
"And now I've caught you," he plays along. "You're all mine." He kisses him sweetly on the cheek. Kissing him down his neck, he whispers to his skin, "Mine." He keeps going down till he moves his legs over his shoulders and he's on his knees, still holding William against the wall.
Mark looks up from in-between William's thighs around his head. "You ready for your extra training lessons?"
William tangles his fingers in Marks hair and nods excitedly. Smirking, Mark moves the white covering out of the way to get to his dick. He looks up to look William in the eyes when he sticks his tongue out to lick the tip into his mouth. Quickly, he sinks down to touch his lips to the base. William tries to cover his mouth when he nearly cries out from pleasure. Gripping Marks hair helps him control his volume. He can feel Mark wrap his tongue around his shaft as he sucks greedily. As if it's coated with sugar. The more Mark bobs his head, the more Williams whimpers start to slip through his palm.
"Fuck- Mark!" He tugs on his hair while he bucks his hips into his mouth, making Marks grip on his thighs tighten. His fingers start to dig into his flesh like he can't bring William close enough to him. One hand lets go to reach up to William's face. He pushes in his fingers past his lips. For a moment, he lifts his head to speak. "Can you get them wet for me?"
Quickly, William takes his fingers in his mouth.
"Good boy," Mark smirks as he takes his cock back into his mouth while he keeps his fingers in his mouth. William holds onto his arm while he sucks on his fingers. Trying to get as much spit as he can on them.
Mark sucks hard, making William bite his fingers on accident. Mark stops, lifting his mouth off to speak. William was about to apologize until he saw the wide grin on his face.
"I like that," he pulls his hand back to lick some of the spit. "When I fuck you, I want you to bite me like that again, okay?"
Again, William just nods his head yes eagerly. "God, I need to bite something if you keep making me moan this loud."
Mark stands up keeping William against the wall with both legs folding against him. He moves one leg to his hip and holds the other to stay on his shoulder, William's ankle next to his ear. "You have no idea what it does to me when I hear you though." He sneaks his hand under William and touches his entrance with his slick fingers, making William shiver. "If anyone was to try and get me off you when I hear you cry my name out like this under me," He pushes his first finger in, starting to pump it in and out. "I'd kill them in a heartbeat." He pushes in a second finger, reaching deeper this time as he fingers him open.
Mark leans in, pressing his chest against Williams as he leans down to whisper into his ear. "If I could keep you like this, whining for more under me, I would." He adds a third finger, hooking his fingers trying to find his g spot. "I would love to keep teasing you, just to hear you more. Hear you cry for me to make you cum."
He feels it, William jerks his head back when Mark presses into his g spot, massaging it. Mark takes this an invitation to lick and kiss his neck. He sucks hickie's into his neck and collarbone as he scissors his fingers inside William.
"Mark-" William chokes out. "I'm cl-" Mark speeds up his fingers, pressing in deeper on his g spot. William is close to tears as he can feel his climax build. Then, he feels Marks fingers leave his ass. He huffs, pouting. "C'mon, I was soo close."
Mark simply tsks and gives William a peck on the lips. "Endurance training, remember?" His smile is sweet, but William's stare is sour.
"Maaaark," he squirms in his hold. "You already owe me for being rough with me." Mark is only half listening as he readjusts his hold on William as he takes his cock out. "Stop being a tease and-" He lines up his cock to his ass and pushes the tip in, making William suck in his breath. Mark moans into his shoulder as he slowly pushes more or his length in.
"God, you're so warm," Mark practically whines, mouthing at his neck.
William tries to pull himself up against marks body. Hard to do when one leg is practically folded up in-between him and Mark while the other is around Marks hip trying to hold on for dear life.
Mark starts to pull out just to shove his cock back in. William wraps his arms around his neck just as he starts to pick up speed, gripping William by his hips and fucking him against the wall.
Trying to keep himself quiet, he bits down on Marks shoulder through the viltrumite fabric and mark moans. "Just like that," he groans into his ear.
The more Mark pounds him into the wall, the more William bites him. The more he scratches his nails against his back. The more he sobs his moans into Mark as he hits his sweet spot over and over again.
"Am I making you feel good?" He licks the shell of his ear as he grunts. "Tell me."
He doesn't let up on his thrust as he lifts his head to look William in the eyes, waiting for his answer. He grabs his chin to make him look at him. Williams eyes are glazed over in pleasure and Mark smirks.
"Mark-" William manages to moan out. He tries to speak more but all that passes his lips are whimpers and moans. Satisfied, Mark leans forward to kiss William. His hand that once held his chin moves down to wrap around his neck as he licks into his mouth.
William sucks on his tongue, gasping for breath every chance he gets while Mark takes his fill of his mouth all pounding him. Finally, William can feel his climax coming back to reach its peak. He double taps his shoulder to single him that he's close and Mark takes that his sign to bend his legs further against him. Making his knee touch his shoulder again while having the other hiked up his hip.
"Please-" William whimpers.
Mark lifts his head to listen to William. "Say that again."
Close to the brink of tears, William moans out again, "Please."
Mark dives in, kissing him hard. He picks up force in his thrust, probably bruising Williams hips and ass. He pulls back, teeth catching his bottom lip and he bites it a little and drawing blood. "You're so addictive." He licks up the blood from Williams lips. "You taste so good, feel so good. Can't wait till you're home with me and I can treat you like this every day."
"God, please-" William whines out just as he cum's in-between him and Mark. His arms wrapped around Mark's neck pull him in and he bites his shoulder again to muffle himself. Mark abandons holding William and grips the wall hard enough to break the concrete, digging his fingers in and he thrusts into William against the wall. With a few last thrusts, he finally cums inside William.
William moans low as he feels himself get warmer from the inside as Mark fills him up. Mark keeps his cock inside, even pushing further in to try to get deeper. They both still as they catch their breath. William's legs around Mark start to loosen though, making Mark let go of the wall to hold him. He kneels to sit down and sit cross legged, with William on top of him still impaled on his dick.
William slumps against his chest. Mark wraps his arms around him, cradling him against him. One hand is petting his head, threading his fingers through William's hair.
He can feel William lift his head off his chest and he looks down to see his face. His cheeks are flushes, eyes hooded, and his lips are parted still trying to catch his breath in soft moans. Still deep inside him, Mark bucks his hips up to get a reaction and he is not disappointed. He quickly shuts his eyes and grips the fabric of Marks uniform as he yelps.
Mark laughs lightly while William hits his shoulder. "Still... Sensitive." William scorns in labored breaths.
"I'm sorry," He kisses his forehead. "You're just too cute not to tease. Sorry, not Sorry."
"That's my line"
"And you're mine. So, what's mine is yours."
William starts to frown but his lips crack into a smile. He giggles as he pulls Mark's face down to kiss him. "You're so corny." Mark simply smiles as he holds him close in response and kisses his lips, his cheeks, his eyes and nose. He tries to lift his hips to start to buck into him again, but a loud bell rings out outside. Mark almost growls in annoyance from being interrupted until he hears William.
"Ugh," William groans. "We have to get back before they start searching for us." He tries to sit up but his legs ache. Mark helps him up off his cock and they can hear the cum slip out. As they stand up, William can help but smile from the humor of the scene. The wall doesn't have a William-shape cut out, but it does have holes where Marks fingers went into the wall. His hips certainly feel the force of Marks fingers as well.
"I'll..." Mark looks to the wall and the cum that spilled on the floor, "...clean this up. I wouldn't want you to be late in check ins." He picks up Williams uniform pants and hands them to him.
William carefully put's his pants back on, leaning on Mark for support as he puts one leg in after the other. Lifting his legs up aches from being stretched like that. Once they both got dressed, William kissed Mark. "Bye Mark. I love you."
Mark hugs him tightly as he kisses his neck. "I love you more."
William pecks him on the cheek before leaning back. "Love you most."
Mark waves him off as William limps away. He almost wanted to help walk him to the sleeping quarters but if he was spotted helping a human, things would have been difficult to explain. Besides, it helps sell his story of "training" if William looks like he actually went through training.
He focuses on cleaning up while he hums, wishing the day he can take William home as his was tomorrow.
______________________________________
It's been 2 weeks since Mark has been on Earth. He missed William dearly but was glad the "training session" was the last time he saw him. He was tasked with a mission to check in on a few viltrumites with their own conquering missions on other planets. As he lands from flying from space, he has to hold himself back from continuing to fly to the human sector where William is kept away with the other humans.
"You're home, Grayson." Kregg greets him from inside the main building. "I read your report that you sent in, the other viltrumites are still in order?"
Mark nods his head. "Yes, sir." His responses are quick and simple. He never speaks more than what is necessary when it comes to other viltrumites.
"Since you have been gone, we made changes to the human resourcing program." He turned to walk, expecting Mark to follow.
He does, concerned. "Changes?"
"Yes, we were wasting too much food on them, so we just reallocated the soldier candidates to be sold off. The human q-"
"What about the slave candidates?" Mark asked, now standing in the way of Kreggs path.
Kregg, confused as to why Mark cares, looked him up and down. "We killed them, no sense in keeping them aliv-"
Mark drove his fist through his mouth, puncturing his skull. The other Viltrumites turned their heads and raised their fist's, surprised. None of them moved when they realized it was Mark.
His eyes were wide with anger. He could taste blood, either from biting his own jaw down so hard or from Kregg's blood spattering on his face.
He swings his arm down, flinging Kregg's pierced head off his arm. He looks down, unsatisfied with the damage and slams his foot down on his skull. Again, and again. Until not even bone fragments remain.
Shocked, the other surrounding viltrumites look on, some even just look down and walk away as Mark obliterates Kreggs corpse.
Once his head turned to mush, Mark turned to the nearest viltrumite. "You."
He straitened up his posture. "Yes sir?"
"Clean this filth off the floor. And let Thragg know there's a job opening in his chain of command," he ordered. He blasts into the air, sending a shockwave into the air. Flying to the retired human quarters he looks to where the corpses could be.
He sees it. Far off in the fields.
A fenced off area labeled "Compost".
When he lands and covers his nose, he can't see William amongst the bodies. He doesn't know if he's glad he can't see William or not. He recognizes some of the faces he trained and were sure they couldn't make the cut to be soldiers.
If William is dead, he would be here. Rotting away.
He starts to turn away and fly off, as far as he can.
He sees the shoreline and he land, rather crashes into the sand as he stumbles. When he screams, the waves deafen. The tears in his eyes distract him from feeling his lungs hurting. His body feels hollow, like his guts plummeted.
He doesn't stop screaming
______________________________________
It's been 6 months since he lost William. He has never skipped a day in training since the day he lost him. Thragg is still alive, not for long though. He made it his goal to kill him and once he's killed him, he'll kill every viltrumite as their emperor. That was the only thing pushing him.
Until a green portal opened up.
