Michael pins Lucifer's wings beneath his own first. They beat back against him, but Michael will teach Lucifer this lesson a thousand times if necessary. He forces his wings into the ground, each struggle only punished with a harsher shove until his brother's wings are trapped and spread flat. Lucifer snarls, trying to arch back against Michael, but with his wings useless, Michael has the upper hand and doesn't plan to relinquish it. He smothers Lucifer's body with his own, chest to back as he wraps an arm around Lucifer's throat tight enough to choke.

Lucifer bucks beneath him. Michael catches his legs between his own to keep him from kicking. He claws at Michael behind him, raising red welts on Michael's sides, but Michael drives him down to the ground. He feels Lucifer's chest jumping as he tries to suck air past Michael's arm. He flails more desperately, his whole body convulsing in a final escape attempt as he runs out of time. And slowly, inevitably, his strength leaves him. He beats a fist weakly back against Michael's side, mouth gaping soundlessly as his eyes glaze over.

Michael presses a kiss to the back of his neck. "We don't have to go through this every time. Submit, little brother." He grinds into the curve of Lucifer's ass as he goes limp beneath Michael. His eyes shut, his face going slack as Michael pushes him to the edge of unconsciousness. "Doesn't that feel good?"

Michael loosens his arm to let Lucifer suck in a breath. His wings raise a little, allowing Lucifer room. He's won.

Lucifer's eyes snap open. His wings lash out beneath Michael. Michael rears back on instinct, exactly what Lucifer wants. It gives him the freedom to twist, to launch himself back into Michael. Michael's hand goes right back to Lucifer's throat, squeezing tight, but Lucifer wraps his around the joint of Michael's wing, pressing down until Michael feels his bones shift uncomfortably. "I'll break your wing, Michael," Lucifer hisses out of his constricted throat. "Try me." Michael squeezes harder, but Lucifer looks wild, eager to tear into Michael in any way that he can.

Glaring up at him, Michael releases his throat. Lucifer's cock twitches.

"You always have it twisted around, brother," he says. He squeezes Michael's wing again, refusing to give up his leverage. Michael grimaces at the pain that shoots through him. "I don't belong to you. I don't submit to you." Lucifer leans forward to nuzzle at Michael's cheek, and when Michael growls, he sinks his teeth into Michael's chest instead, right over his heart. "I'm yours," Lucifer emphasizes. "I'm yours, your world revolves around me, I'm all you'll ever need." He settles back until Michael's cock presses against his hole and takes him down to the root. Michael can't help the way he groans, caught between his brother's tight heat and the hand still threatening to snap his wingbones.

"Say it," Lucifer demands as he rides Michael. If Michael can't fight to win, he can at least fuck Lucifer harder. He meets Lucifer's hips with thrusts of his own. "Say I'm yours."

"You're mine," Michael agrees. It feels like defeat. Lucifer chases it, a constant stream of, say it, Michael, admit it, tell me, tell me, tell me, until Michael can't help but give him what he wants. Buried inside Lucifer, he says, "Mine, my little brother, my everything."

Lucifer's wings rise with pride as he wraps his other hand around his cock and marks Michael's chest with his come. It mixes into the blood of the bitemark he left. He slows for a moment to enjoy the sight before he keeps riding Michael, never satisfied.
