Sebastian's hand slid down Kai's chest, slow and deliberate, trailing over the ink and sweat until his fingers wrapped around Kai's cock. Kai's breath stuttered, his hips jerking forward before he could stop them, chasing the grip like an animal seeking heat. The cold glass pressed into his back, the mirror cool against his flushed skin, and he saw himself in it — lips swollen, eyes dark, body already surrendered to Sebastian's rhythm.
Sebastian's other hand flattened against Kai's chest, holding him still against the glass. His thumb found Kai's nipple, a casual torment, while his fist worked a steady, unhurried pace. Kai's hips rocked in counterpoint, the slide of his cock through Sebastian's grip wet and slick with precum. He hated the sound of it, the wetness spreading over his own thigh, the way his body kept pushing forward like it had a mind of its own.
Sebastian slowed. Just a fraction, just enough to make Kai's rhythm stutter. Kai's hips kept rocking against nothing, seeking friction that wasn't there, and the loss was a white-hot ache. His mouth opened, but the word stuck in his throat — please — he could taste it, bitter and sweet, but it wouldn't come out.
Sebastian's grip tightened, then slowed further, a punishment for the hesitation. His thumb dragged across the head, spreading slick, and Kai's whole body trembled, a broken sound escaping his lips. Sebastian's eyes met his in the mirror — gray-blue, patient, waiting.
"Yours," Kai heard himself say, the word rasped and raw. Sebastian's hand stilled, and the silence stretched, unbearable. "I'm yours."
The admission cracked something open in Kai's chest — a door he'd kept locked, bars he'd held against his own ribs. It hurt, a sharp, clean pain, and he felt tears prick at his eyes again. But he didn't look away from that reflection — his own face, stripped of everything but this truth.
Sebastian's hand moved again, faster, rougher, the grip tightening as he stroked Kai toward the edge. The friction was too much, not enough, and Kai's hips bucked into it, his hands pressed flat against the glass. The cool surface bit into his palms, grounding him even as the heat built low in his belly, coiling tight and relentless.
The orgasm hit like a fall — not relief, not release, but a brand searing through his veins. Sebastian's fist worked him through it, not letting go until Kai's body had nothing left, until the aftershocks faded to trembling, and the room went quiet except for his ragged breathing.
Sebastian let him go. Kai slumped against the mirror, his forehead resting against the glass, the cold sharp against his flushed skin. He watched his reflection — cock softening, cum dripping down his thigh, a mess he couldn't clean. Sebastian's hand returned to his chest, palm flat over his heart, and Kai felt its heat through the lingering tremor.
"Good boy." Sebastian's voice was low, almost gentle. He said nothing else, but his thumb traced a slow circle over Kai's sternum, and Kai's eyes stayed on their reflection — tangled, broken, branded.
