Erwin's hands are down Levi's pants before they even reach their room.
"You're eager, aren't you?"
"Of course I am," Erwin says, opening the door to their room and pushing Levi gently inside. "I've been waiting for this for a long time."
Levi swallows, "How long?"
"Very long," Erwin replies.
Levi desperately wants to ask how long – the idea that Erwin has been interested in him for a while seems absurd - but decides to let it go. They can leave that conversation later, because right now he wants to be with his Alpha.
Erwin slowly pushes Levi's jacket to the ground, followed by the unbuttoning of his shirt and unzipping of his pants. Levi has to bite his tongue in order to stop himself from whining impatiently.
"You're so beautiful," Erwin breathes.
Considering Erwin's perfect body, Levi knows he's not anywhere near the definition of beautiful. He turns his head away so that Erwin doesn't see the insecurity in his eyes.
"Hey," Erwin whispers, soft and concerned. His fingers run lightly down Levi's cheek. "Are you okay?"
Levi nods, "I'm fine." There's no point in letting his stupid insecurities ruin this moment for them.
"You'll tell me if something's wrong, won't you?"
"I will." Levi leans forward to start taking off Erwin's clothes. "As long as you stop worrying about me so much. I'm fine. I'm not going to break. I want this."
The rest of their clothes are quickly shed, leaving a trail on the ground leading up to their bed. Levi pushes Erwin onto the bed, moving quickly to pin him down, legs straddling his hips tightly.
"Levi," Erwin mutters breathlessly.
"I may be the Omega, but that doesn't make me the bottom," Levi purrs into Erwin's mouth, capturing his lips in a kiss, full of teeth and tongue.
Levi rocks forward, trapping Erwin's hard cock beneath him. Erwin moans shamelessly as slick drips from Levi's hole onto his body, further fuelling both their lust.
"Fuck," Erwin cries when their lips part for air.
Levi gets a sick sense satisfaction from having an Alpha so willingly stay bellow him, raking his fingers down Erwin's rock hard abs.
Erwin grabs one of Levi's hands, entwining their fingers. "Whenever you're ready, Levi." He's fully prepared to go at Levi's pace, and Levi couldn't feel more affection for the man than in this moment. But he wants – needs – to be fucked, and the slow pace is killing him at this point.
Levi bites on his lip hard as he sinks down onto Erwin's length without warning, who graces him with a surprised groan.
Levi whimpers as he bottoms out, the feeling of Erwin inside of him is far better than what he remembered. Quite suddenly, he feels his whole body warm up and fall weak. Any strength he once had to hold Erwin down is now gone, replaced by a shaking, writhing mess.
Erwin's fingers dig into Levi's hips, lifting his body slightly and dropping him back down. It feels so good, but it's still not enough, and soon Levi is desperately moving his hips up and down with whatever strength he has left.
"Shit," Levi chokes, "Shit, Erwin."
He can feel his Omega senses take over, and the need to dominated and claimed by his Alpha pulses through his veins. He wants Erwin to hold him down and pound into him ruthlessly with no mercy until his knot fills him up and he comes inside.
God, he wants it.
Erwin dives forward to scoop Levi up and pin him down on the bed. He growls like an animal and Levi shivers at the Alpha's display.
"Take me," Levi gasps, bearing his neck and scent gland for Erwin. "Erwin, take me."
Head buried in Levi's neck, Erwin starts thrusting forward in earnest. Levi can't help but let the moans and screams fall from his lips as they mix in with Erwin's grunts and growls.
It's not too long before Levi feels Erwin swell inside of him and completely loses it at the feeling.
"Oh fuck, Erwin!" Levi shouts, coming hard. "Fuck, fuck, fuck."
Levi's body falls limp as Erwin continues to thrust forward, but he doesn't stop making noises as he Erwin's cock swells even further inside of him. It feels fucking fantastic, but it's so much – almost too much – and Levi considers trying to push Erwin away, but he knows it's too late now and Erwin's going to come at any moment.
Erwin's hold on Levi tightens, teeth sinking into his shoulder as he comes with a large grunt. Levi squeals at the feeling of Erwin's cum, arms and limbs flailing due to sensitivity.
"Ah," Levi pants, feeling himself grow hard again, "Alpha… Your knot…"
Erwin slowly clears the haze of his orgasm and reaches down to lazily jerk Levi off. "Feel good?" He pants into Levi's ear.
Levi can't do anything but hold onto his Alpha and frantically nod. Erwin's knot has stopped growing and is now firmly anchored itself inside of him. It makes his entire body heat up, desperate for release.
"Come, Levi," Erwin commands into his ear. "Come for your Alpha."
Erwin's words push Levi over the edge again and his weak body trembles in aftershocks over Erwin's cock. Erwin holds him through the whole thing, pressing light kisses over any skin that he can reach.
"Are you okay?" Erwin asks, pulling Levi onto his chest after he stops writhing.
"Stop worrying about me," Levi says, voice soft from overuse. "I'm fine… More than fine, really…" Levi bites his lip and snuggles further into Erwin. "Your knot feels really good."
Erwin smiles and presses a kiss to Levi's forehead. The two stay embraced until Erwin's cock slowly returns to normal state. When he pulls out, thick globs of cum and slick start dripping out of Levi's hole.
"Ugh, fucking disgusting," Levi mutters. "The sheets are getting dirty."
"I'll clean them in the morning," Erwin replies.
Erwin spends the rest of their night wiping down a very sleepy Levi with a wet towel, stopping every now and then to place a soft kiss onto his body while Levi internally thanks every God imaginable for gifting him with such an amazing, considerate lover.
