Koki smells smoke and sweat and cologne and perfume and alcohol and Jin's breath panting on his neck.

Jin went to the very bottom of his wardrobe for this outfit. Jeans he hasn't worn since last summer, frayed at the cuffs and artfully slashed above the knees and below the ass. Koki hooks his index finger through the denim and prints a crescent with his nail into the bare skin of Jin's thigh.

Jin opens his mouth on Koki's neck with a laugh. His tongue drags up to Koki's ear, and his voice is thick and drunk when he whispers, "Go higher."

Apparently there aren't boxers at the bottom of Jin's wardrobe.
