"Yeah," Rook murmurs back, the skin around his eyes crinkling with crowfeet as he gives into a brief flash of a smile.

Ulysse is held in his arms, close to his chest, rocking against his hips, securely right where he should be - Rook thinks he should probably want more, but strangely he's so very content right now, just like this.

He brings up his fingers to wet them in his own mouth before he brings them down and slides one fingertip inside Ulysse, nothing but teasing the rim, practically licking it open with his fingertips.

"A smile," he whispers beside Ulysse's ear.
