Aventurine's arrival is marked by the familiar sound of the door closing, but it's as though the air around him has shifted. The weight of the world that lingers on his shoulders seems to be pressing harder today, and yet, when he sees you sitting on the sofa, an odd flicker of calm settles within him.

The moment your eyes meet, he’s already moving, the tailored jacket discarded carelessly to the floor, the swift sound of his shoes against the hardwood flooring reverberating through the space. Each step feels heavy with intent as he closes the distance between you, his gaze focused and unwavering. His sharp eyes soften for just a heartbeat, but the tightness in his jaw speaks of something else—an urgency, a need that has nothing to do with the world he manipulates and everything to do with you.

You rise instinctively, drawn to him by the pull of something unspoken. You’ve been here before, in this silence that has no need for words. But before you can even form a greeting, his lips are on yours. The kiss comes suddenly, almost violently, as though he's been starving for something—anything—real in a world full of calculated moves and distant promises.

The rush of warmth from his body, his scent, his very presence overwhelms you. His hands move swiftly to your waist, fingers slipping under the fabric of your shirt, his touch frantic as if trying to find some comfort in the familiarity of your skin. He pulls you closer, not giving you a chance to breathe, not wanting to give you space. There’s a hunger in the way he moves, an almost desperate need to lose himself in this moment.

Without breaking the kiss, he guides you with a surprising tenderness toward the bathroom. The cool light from the overhead lamp does little to dampen the fire between you, the space suddenly feeling too small, too contained for the heat that’s building between your bodies. His hands roam over your back, down to your hips, grasping and pulling, his lips still demanding, relentless.

Then, as though remembering something, he breaks away. His breath is heavy, his face flushed from more than just the intensity of the kiss. He moves to remove his gloves, the action slow, deliberate, as though the simple task is part of the ritual that comes with shedding more than just his accessories. His teeth graze the leather of the glove, pulling it off with a quiet, almost animalistic precision. He doesn't give you a chance to speak, his gaze never leaving yours, every motion part of an intricate dance of dominance and surrender.

The room grows smaller still, filled with nothing but the steady pulse of his desire, and the unmistakable feeling that nothing in this moment can be controlled—not the world outside, not even the roles you've both played. There's only the rawness of the connection, the heat of his hands now unburdened, free to explore what has been so long suppressed.

In this space, with the walls too close and the air too thick, Aventurine is no longer the strategist, the calculated gambler. He’s simply a man, caught in a moment of wanting.
