Barcus may have to think about that one. Friendship plus attraction seems like perfectly reasonable criteria to him, but he is more restrained than that, himself. Mostly because he knows he inevitably gets attached and there's a limit to how many hurt feelings he cares to endure. He hums thoughtfully and takes one last sip of his brandy, letting it linger on his tongue with he full knowledge that he's about to be kissed.

In the end, he decides, what matters most is that Bel thinks of him as a friend. Maybe a friend and something else.

He lets Bel lead, sensing he's being cautious, but once they're together, he takes over willingly, arms slipping around his shoulders to hold him close enough to deepen the kiss. In spite of the urge to bite, he's gentle, but he is very thorough, eventually standing on the rung of his stool again in order to press closer against him.

Eventually, breathing becomes necessary, and he breaks off with a little sigh, nuzzles under the drow's chin, and nips the side of his throat with a soft mmmm.
