It was sure as hell working. He whimpered when Duo spoke, tipping his head back far enough that he could meet his lover's gaze, if only for a few seconds as those fingers slid free of his mouth. When Duo wondered about finding another, his ears twitched as he licked his lips.

"I'd settle for--" but then Duo did the thing he was going to suggest, his eyes sliding closed as he rocked back against the fingers. It might not have been the best lube, but it hardly seemed to matter to him, a low moan rumbling through him. "Fuck," his thoughts dissolved to sensation, to pleasure and desire, heat and pressure and those fingers. He tipped his head forward, forehead thunking gently against the door as he shifted his legs farther apart.

Yours, the only coherent thought making its way through his mind, surging louder every time Duo's fingers eased a little deeper. He wanted so much that he didn't know how to express, so it just came across as a carnal hunger, not at all satisfied with mere fingers.
