“Kneel.”

Erwin obeys. His strong body falls like a mountain before Levi, both knees hitting the ground with a soft thump on the pillow, eyes cast downward to the floor. Levi runs his finger along Erwin’s spine, nail leaving a red scratch mark. Erwin groans like a chained beast, his back bucking up, wild shudders shaking him all throughout his being. Levi smiles.

“There’s my good boy. Open your mouth.”

Erwin obeys, again, and when Levi grabs his collar and tilts Erwin’s head back, his lips are parted and tongue sticking out, desperate moans spilling from his bobbing throat where he’s swallowing, hard. Wanting, desiring his man. Then Levi’s slinging one leg around his neck. Erwin instinctively holds it in place, fingers reverently dancing to his Dom’s ankle, wrapping around it like it’s precious silver.

“Give it to me, nice and slow.” Levi’s voice is quiet thunder.

Erwin closes his eyes and nods, whispering “yes Sir” with a wide smile on his lips before his mouth opens and he licks fire between Levi’s legs, pushes inside, feels him tight and hot and twitching on his tongue, and hears his Dom moan when the grip on his collar tightens and Levi rocks his ass right into his wet greedy mouth.

“Good – ah, fuck. Shit, just like that, you’re so g-good…”

Levi’s voice breaks, and Erwin feels his cock pulse, heavy and swollen between his legs. He’s not allowed to touch, doesn’t even want to. Not when Levi’s ass tightens around his tongue, presses down, how that leg around his neck goes heavy and suddenly Erwin’s holding his Dom upright, hears him groan and feels fingers rip at his hair, his collar with the silver ring on it.

Erwin loves how Levi pulls back just before he comes, and he’s closing his eyes and leaning in when warm, milky cum drips over his face and into his open mouth. Levi’s still panting. His leg slides off Erwin’s neck, both feet firmly on the ground again. Erwin swallows. Everything. His cock’s still hard but he doesn’t care. He doesn’t care until he hears Levi sink down and kiss his dirty mouth.

“Thank you,” Levi whispers as their foreheads touch, and the collar slides off Erwin’s neck when Levi opens the lock. Erwin opens his eyes, notices Levi’s watching him, unspoken question in his eyes. “Are you okay?”

“I’m the one who has to thank you,” is all Erwin says before he wraps himself around Levi, curls in his lap and feels Levi card fingers through his hair. He smiles when kisses are being pressed to his head, and thumbs trace where his collar was moments ago.

“You were perfect,” Levi whispers. “My good boy.” Erwin makes a dark noise at the nickname and then closes his eyes, trusting Levi to take care of him.

He always does.
