He never meant to leave you behind. That much, he convinced himself of. When Sōsuke Aizen turned his back on the Soul Society, when he abandoned all the familiar corridors and ancient rules of Seireitei, it was strategy. Power. Ascension. You were the only variable he didn’t account for—an ember he expected to extinguish with time, only to find it glowing brighter in the deepest recesses of his mind.
He thought of you often. Every day, in fact. At first, in idle passing, your voice when you scolded him for staying up too late, your eyes narrowing whenever he made a comment too smooth to be innocent. But soon, the recollections became consuming. Your laughter haunted the silence of Hueco Mundo. Your scent lingered in phantom moments. And at night, when solitude pressed upon his mind like a curse, Aizen would sit alone in his throne, eyes half-lidded, hand wrapped tightly around the painfully hard member sitting between his legs— breathless and murmuring your name like a sacred mantra.
He sent Ulquiorra to watch you. Of all the Espada, he trusted him to be emotionless, clinical. He didn’t want your life disturbed, only documented. What you wore. Who you smiled at. Who you visited. How often you laughed. And when the Fourth returned one day with a quiet, “there’s another man present,” Aizen didn’t blink. He didn’t speak. But the temperature in Las Noches plummeted, and the throne room fell into silence. His knuckles went white around the armrest. That night, he didn’t touch himself. He couldn’t. The thought of someone else having your smile, your time, your body, it was blasphemy.
So he sent Ulquiorra one last time. Not to watch. To seize. “Do not harm her,” he said, voice low and calm, but filled with a promise of torment should that order be disobeyed. And when you awakened, dazed in the sterile white void of Hueco Mundo, he stood waiting—still pristine, still polished—but something in his gaze was… fractured.
You didn’t run to him. You didn’t even speak. You just looked at him distain—like all the warmth you once held for him had rotted into something bitter. “You betrayed us,” you said, your voice steady. “You betrayed me.” That was your answer. And it destroyed him.
But Aizen didn’t falter, at least not fully. Not in front of the Espada, not in front of Gin and Tosen. He remained composed, commanding, ever the god ascending. But when it was just you… when the doors closed and you stood across the room refusing to flinch under his gaze… he shattered. Not visibly, not yet. “I think of you,” he whispered, walking closer. “I thought of you every day. I touched myself to the thought of you—every inch of you, every sound you make.” And then, impossibly, he sank to his knees before you, his emotions no longer an abstract concept. They spilled from him, heavy and undeniable.
“Lie if you must— say it, even if you hate me. Say you belong to me, say it was always me.”
Your silence was the cruelest cut. So he rose again, and this time, his voice turned velvet— dangerous and irresistible. “You will,” he said. “You will remember how it felt to be mine.”
He didn’t need Kyōka Suigetsu to manipulate you. No illusions. No lies. He would give you the truth instead. Every fevered thought, every unspoken craving—he would pour them into you. His lips would find yours with the precision of a man who’d memorized exactly what you craved, drinking in your breath like it belonged to him. His hands, used for control and conquest, now trembled as they traced the curves he worships. He would take his time, relearning your body like scripture, whispering your name against your skin as though it could summon the past. And when you trembled beneath him, when your voice cracked in that familiar way, he would take you—over and over—until your body surrendered underneath him, until it betrayed you, until it remembered the man your mind swore it forgot. He wouldn’t stop until your walls broke, moaning for him to consume you, until desire eclipsed reason and all that remained was the truth: you were always his.
Because Sōsuke Aizen does not yearn often. But when he does, it is absolute. And he only ever yearns for you.
Just a little more guilty pleasure until i finish the kissing game for my bleach boys <3
