The second Sea stepped into the empty music room, he knew he was in trouble.
Boss was already there. Sitting on the edge of the grand piano like a king on his throne—legs spread, shirt half unbuttoned, jaw clenched. The moment he saw Sea, something wild flashed in his eyes.
"You made me wait," Boss said coldly.
Sea opened his mouth to speak but didn't even get the chance. Boss was on him—slamming the door, dragging Sea by his waist, shoving him onto the piano. Keys groaned under Sea's back, a loud clang echoing through the room.
"You're mine, Sea," Boss growled into his neck. "You don't walk away from me. You don't smile at anyone else. And you definitely don't let anyone touch what belongs to me."
His hands were rough. Desperate. Tracing every inch of Sea's skin like he was memorizing it. He ripped open his shirt—not unbuttoned, ripped. Buttons flew.
Sea gasped, back arching when Boss's mouth found his chest, biting hard before soothing with his tongue. Every touch was a war between punishment and worship. And Sea was losing his mind.
"Look at me," Boss demanded, fingers gripping Sea's chin. "Look. At. Me."
Sea whimpered, eyes locked to Boss's as his trousers were yanked down. Cold air. Then hot skin. Then Boss.
No mercy.
Boss thrusted into him in one brutal push. No warning. No hesitation.
Sea screamed. Not from pain—but because Boss filled him completely, stretching him like no one ever had. Tears gathered at the corners of his eyes, but his mouth curled into a wicked smile.
"Again."
That was all Boss needed.
He began pounding into him, hard enough to rock the entire piano. Keys smashed under Sea's hands as he gripped them for balance, every thrust forcing a broken sound from his lips. Gasps. Cries. Moans that echoed.
Glass behind them fogged. Then cracked.
Boss slammed Sea against it, lifting one leg high to thrust deeper. Harder.
Crack.
"Beg for me, baby boy," Boss rasped, licking sweat off Sea's jaw. "Tell me who you belong to."
"You!" Sea cried, nails dragging down Boss's back. "Only you. Always you—fuck—don't stop!"
And Boss didn't. Not until the glass shattered behind them. Not until Sea screamed so loud the entire school probably heard. Not until Sea collapsed on the piano, trembling, panting, ruined.
Boss kissed his forehead gently, contrasting the violence of before. Then whispered, "Mine. Forever."
