edit: someone asked for an ID, so heres the one they wrote (plus some extra edits by me):
[ID: Digital Magnus Archives fanart of Jon and Martin kissing in an archive’s closet. Martin holds Jon, one hand on Jon’s neck and the other holding his waist, bending Jon backwards a bit. Jon has one hand cupping Martin's jaw/cheek and one on his chest. The closet is small and dim, but a single green lightbulb above them emits a starburst glow and casts them in green light. A little bit of light emits from the door through the shades down to the ground. End ID]
