After a long day of fetching rations, Levi told everyone to go out and make a fire, there was a bit of meat he could get and they were dying to cook and eat it.

When Eren was about to leave, Levi stopped him. "Oi, brat, go to the basement. You don't get that meat."

Confused and sad, Eren heads to the basement. As he reaches the bottom, Levi shoves him in a cell. Eren falls back onto the small uncomfortable bed and looks at the captain. More specifically, the prominent bulge in his pants.

"C-captain Levi.. why am I in a cell?" Eren manages to get out before gulping as he tries to size the bulge. got to be at least 7 inches..

Levi smirks, standing at the opening of the cell. "You're getting a punishment for not cleaning well enough." He sees Eren staring at his crotch and scowls. "Brat stop staring and start sucking."

Eren turns bright red when he says that, "b-but Captain that's what a g-girl does. I'm not a girl." He tries to cover his face but Levi goes over and grabs his arms, chaining them to the wall like they were so long ago. 

"Are you refusing an order?" He raises an eyebrow and stares into Erens beautiful sea blue eyes. "Now suck."

Eren reluctantly starts to take off Levi's pants, difficult since he still had his straps on and his hands were chained. But he uses his teeth to obey his order, pulling on his zipper and seductively pulling his pants down. Levi groaned at merely the sight of it, but wasn't near satisfied. His large 9 inch cock sprung out of his pants and hit Eren's cheek making him bright red.

Sure Eren wasn't lacking in that department, but he wasn't nearly as long or thick as his superior.

Eren slowly kisses the tip, making small light kisses up and down his shaft on all sides, he reaches his balls and starts sucking on one. Levi groans again, delighted at the feeling, he sets a hand on Eren's head and grips a bit at his hair. Eren moans softly at the feeling and goes back to the tip of his captain's long cock. He slowly starts to bring it into his mouth, he gets halfway and almost gags on him. But that just sent vibrations all the way up Levi, he moaned slightly and starts to slowly thrust into his mouth, only half of it getting in his mouth before he gags and sends that wonderful vibration again. Eren moans the next time it hits the back of his throat, and he tries to go deeper onto his cock, taking the whole thing in now it went into his throat deeper. He began to swirl his tongue around his shaft, pulling off to breath before going just as deep again. Levi keeps moaning at this and begins to feel himself getting close. 

He bends down and pulls his dick out of Eren's mouth, whispering hot breath into his ear. "Do you want to taste my cum brat? Or would you rather it be somewhere else?"

Eren looks confused, "w-where else would it be Captain? I'm not a girl and don't have the right hole for it."

Levi scoffs, "who said it was wrong or right? You have a hole made to fit my cock and be filled with my cum. Do you want it there or would you like to taste your captain?"

"I think you are mistaken, I have no hole for-" but before he could finish Levi shoved him down on the bed. Climbing over him he begins to pulls his pants off, no care for the gear he is wearing. Levi stares down at the titan, he grabs the front strap of his upper gear and lifts Eren's lower body off the bed.

As he lines up to the younger's asshole he looks at him, "this might hurt a bit." And he slowly starts to enter him.

Eren winces in pain at the foreign feeling, he looks down to see the Captain not even halfway in, how is he in so much pain and not even endured half of it! 

Levi groans and slams the rest of his cock in, Eren screams in pain. Levi hates the sound and stops, whispering seductively into his ear, "tell me when I can move brat." He waits there while Eren shifts around, wanting to move his hands and cover himself or to cover his mouth at least, but that is no use. He moans every time he moves a bit in one direction and Levi takes the hit that he's more sensitive there. He slowly starts to move his hips so he'll start thrusting directly there, but he has to wait until Eren says,
"Move Captain~" 

And immediately Levi pulls his cock almost all the way out, and slams into that sensitive area making Eren's eyes roll back and he moans loudly, "Captain~! Wh-what are you doing?!" But Levi doesn't answer, he just grabs Eren's hips and keeps slamming in and out at that spot. "Captain~!!!" he moans over and over again.

Levi slaps his ass and whispers to him, "It's Daddy or Master from now on brat." And he slaps his ass again, slowly creating a red mark.

"Master~ I feel weird~" as Eren says this his own cock starts to swell, but before cum can erupt from his dick, Levi holds his thumb over his tip, squeezing him. Eren whines and starts to whimper, "Master what.. what are yoU~!!!" He moans loudly as Levi slams deeper than before.

Levi whispers to him, "Beg to cum, slut~" Eren's eyes widen at the name, unintentionally squeezing his ass tighter around Levi's cock. Levi moans at the feeling, "fuck squeeze me again slut!" He yells and slaps his ass again.

Eren does so and looks at him, "Master let me cum~ I'll be your little brat and bitch~ you can fuck me whenever your fat cock wants~ just let me cum Master~!" He moans as Levi removes his thumb and starts pumping his cock.

"You were always going to be my cock whore~" He slams into him and cums deep against his sensitive area.

Eren cums immediately at the feeling, so many white ribbons of cum flow out of his cock, the feeling of his cum swishing around in his ass is too much to handle. Levi doesn't stop thrusting in and out of him, already rock hard again.

Eren feels overstimulated and starts shaking, "Master I can't... I can't take more~" But Levi doesn't stop, he slaps his ass.

"You're my little cum slut and you can't even take another round? Useless brat." He grips Eren's neck rather than his cock, getting an even better angle to slam into him deeper, squeezing his neck.

"Ma.. Master!!" Eren's breathing gets weak, trying to reach for Levi's hand to pull it off, but he pulls against the chains. His wrists hurt, but it just makes Eren moan louder, it's such a good feeling, the cold metal against his skin, how beautiful a sight. "so good~" he moans through his short breath.

Levi smirks and starts to speed up his thrusts, "struggle Brat, struggle against it all you want~" and so Eren did, he kept yanking on the chains, and moaning, Levi loosens his grip on his neck and lets him breathe more.

Eren looks at Levi and immediately starts squeezing around him again. Levi groans and glares at him. "What a good slut~"

"Only for you Master~" he moans and Levi takes his hand away from his neck, he whimpers a bit at the lack of feeling. But immediately starts to feel so good when Levi begins to shove Eren's leg up more. he puts the leg over his shoulder and he keeps pounding into him mercilessly. "Fuck! Master so good~!!!" Levi smirks and goes even faster. His thrusts became a bit sloppy but he kept going.

Eren cums again all over his shirt, Levi smirks and whispers, "You got a bit dirty Brat, I don't like dirt." Eren gulps, but immediately shivers at the feeling of Levi pulling his shirt off, ripping it off around his chest. Levi slows his thrusts and reaches a hand up to his nipple. Squeezing and pinching at it, Eren moans louder. 

Confused, "Master nothing will come out, why do that?"

Levi smirks, looking at him, "because you're slutty hole isn't squeezing enough, so I thought I'd show you what it means when you squeeze." He squeezes his nipple and flicks it, messing with the erect pink bud. 

Eren moans at the feeling, shivering every time Levi's cold hand brushes against a new part of his hot chest. "Master fuck me harder~ I'll squeeze you like the bitch I am~" 

Immediately after hearing that, Levi slams into him deeper than before, slamming into his tight ass. Eren squeezing him tightly as promised and Levi moans at how it feels. "Brat you're so good at this~" He leans down and starts sucking on Eren's nipple. Biting at it, Eren screams in pleasure.

Cumming again, Eren hits Levi's shirt and chin with his white ribbons, Levi pulls off his nipple and looks down, "Slut you got me dirty." He wipes the bottom of his chin and smears the cum against his cock, "You're a dirty pig, Eren~" He squeezes the remaining cum out of Eren's cock and goes even deeper than before and cums in him.

Pulling out, he pumps his own cock, trying to get the rest out and in Eren, but it starts dripping out of his ass either way. Eren's body starts shaking from the overstimulating activity, and Levi watches him as he gets up, wiping off his dirty cock and zipping up his pants. "I'll be back down, Eren. Keep your ass nice and tight for Master~" 

Eren, helplessly chained up, sprawled against the uncomfortable bed and covered in his own cum, nods and lays down, squeezing his ass to keep the cum in. He mutters sweet nothings to himself, "i finally got master... I love him so much..." and many more. 

 Levi, however, goes upstairs and sees a few smirks and winking faces. Especially some coming from his friend. Hanji looks at him and smirks, "So Levi, How did the shifter react to pleasure? Was he any different from anyone else you've done this.. activity with?"

He scoffs, "Oi, study him later, I'm not done with him." Mikasa starts to rage in the corner, quietly cursing the captain out, but Armin just looks worried for his friend. Levi walks to his room and grabs a bag of supplies and starts heading to the basement again.

Mikasa shouts after him, "I'll kill you if you hurt him!"

Levi looks back before closing the door to the basement, "then why aren't I dead yet?"

So... I wrote that on discord, because a truth or dare bot made me write a 300 word thing, but that wound up being almost 2000 words. 

Anyway, that was interesting... 

If there are more smut ones, they'll have the warning in the title and a blank space so skip it if you're uncomfortable. That's it. Have a good day.
