Dean pulled back slowly, their bodies still joined as the last tremors faded, his forehead resting against Castiel's while their breaths mingled in the humid air. "God, baby, you're everything," he murmured, the pet name slipping out raw and tender as he pressed soft kisses along Castiel's jaw. Castiel's fingers threaded through Dean's damp hair, holding him close. "My hunter, my Dean," he whispered back, voice husky with lingering pleasure and centuries of devotion.

Their legs shaky but hearts racing with renewed hunger, Dean eased Castiel down from the sink and guided him toward the bunker's narrow hallway, their slick skin brushing with every step. Without warning, Dean spun him around and pressed him firmly against the cool concrete wall, the sudden chill contrasting the heat radiating from their flushed bodies. Castiel gasped, his cock already twitching back to life against the hard surface as Dean's hands roamed possessively over his hips and ass, spreading him open once more. "Need you again, angel—right here, just like this," Dean growled, his own erection hardening against Castiel's thigh, the thick length dragging teasingly along sensitive skin.

He lined up and thrust in deep with one fluid motion, burying himself in Castiel's still-wet heat, the tight clench drawing a shared moan that echoed off the bunker walls. Their bodies moved in urgent sync, Dean's hips snapping forward in a relentless rhythm that pinned Castiel in place, skin slapping with each powerful stroke while his hand reached around to stroke Castiel's cock in time. Sweat-slicked chests pressed together, nipples brushing, the friction building an electric charge that made every nerve sing. Castiel arched back into him, fingers clawing at the wall as waves of pleasure crested again, their bond pulsing hotter with each whispered vow of forever amid the raw, gasping thrusts.
