The grin never left his lips as he bit and licked at Kirei's neck and chin, not hard enough to leave any marks but just so Kirei could feel it. Gilgamesh slipped the fingers of his other hand into Kirei's collar, undoing the fabric and sliding his fingers in to spread them across his collarbone. Just touching lightly, smirking down at Kirei, before he started pulling his clothes open. Not completely, just enough to expose enough skin, flatten his hand over the space where the man's heart once beat.

He dug his fingers in, dragging his nails across the skin as he smirked, nipping at Kirei's chin. "It is always fascinating to see you like this, Kirei."

Honest for once, and then Gilgamesh pressed his lips to Kirei's, daring to slip his tongue along one lip.
