Raju's teeth are around Francis' left nipple a little after that keening noise starts, eager to take all the noise Francis is making and make them louder, more, take the pleasure he should have been giving Francis before and give it to him all at once. He isn't biting down at all but holding Francis' sensitive skin firmly enough in his mouth to gently pull, experimentally, then Francis chokes and Raju lets go and looks up at him, waiting to make sure he's alright. Francis hiccups once, and it's confirmation enough that the choking wasn't anything serious; Raju smiles warmly, softly, and then his free hand goes back to twisting Francis' nipple between its fingers.

"Is this alright?" That keening, delicious as it is, isn't a noise he hears from Francis often; the pause to be sure of Francis' even breathing has Raju thinking he'd better make sure, though not without one more lingering moment to suck Francis' nipple in his mouth. His lips pop back off again with a wet noise and his voice comes out rough, he speaks in the same moment he grinds his hips in the same lingering way into Francis' again. The sensation of it has his fingers tightening around Francis' other nipple; he doesn't mean to, but he doesn't mind that it's happening, either. "Too much?"
