[ As is the case with all things Sion, Naoto is going to eventually want to kiss places.

... So he does! He kisses Sion's shoulders and neck and then just wanders down, kissing across his collarbones, then between them and below them, moving past Sion's chest and down to his stomach to kiss just above (and then just below) his navel—

—And of course he does this all in the usual way— gentle, careful, waiting for a reaction between each and every one. Godspeed Sion. Godspeed. ]
