To Sam, Bucky tastes like the crisp air of a beautiful winter night, like the promise of snow in the best way possible. He's like something refreshing, something that soothes you on a hot day. Like the first sip of water after a desert. The slide of their lips is beautiful, and Sam hums in pleasure when he feels Bucky relax, away from the erratic breathing.

And after, he just looks at his mate. Doesn't look down at himself, doesn't behold the way he's become radiant in a literal sense. Just looks at Bucky. And in the depth of Sam's brown eyes, flecked with gold, Bucky will see his own light shining back to him.

"That's all you, Bucky."

Takes Bucky's hand, places it on his skin. Lets him feel the warmth, the light. The glow of a sun who lifts up his moon instead of treating him like a shadow.

"See what you can do?"
