It's certainly not the strangest thing Chris has ever told him. It feels like it might be bad to injure the siren's gills, but he seems to be taking to this well. And if it helps to soothe Chris' worried and fractured mind? It seems worth it to indulge. Even if it's strange.

How did he end up with a masochist? And a sadist. Jon is hyperaware of the claws straining not to stab into him and tries not to let it pull his fear to the forefront too much.

"Mm..." Biting. He's been given leave to bite and that's something he likes doing. Maybe there's a part of him that's just a tiny bit sadistic. Jon bites into the place he's just been kissing, careful to angle it so he avoids anything that might actually tear at the gills. But maybe a bit of bruising? He doesn't hold back in strength for the first bite, but eases off quickly to lick and kiss the spot.
