It's funny, Yoongi thinks, what things trigger which reactions. He's not the least bit embarrassed about what they did in the bathroom, but thinking of Jungkook in public, licking sugar from his fingers, brings a flush to his cheeks, as much because of how he reacted back in December as anything else. Thankfully, standing like this, Jungkook's back flush against his chest, it's easy to hide that.

"As long as I can lick it off," he teases, voice kept low. "But I like anything I can lick off your fingers." He tries not to let himself think about that too much, though, not when there's still plenty of this place he wants to see. There are children pressing up against the glass alongside them, and his gaze drops to a little boy trying to wave a toy at the fish through the window. He smiles, watching him wriggle the stuffed crocodile emphatically against the glass, trailing it up and down to catch the fishes' attention. It's enough to distract him from anything dirty-minded for the moment, too charmed by the innocence of the moment for that.
