That said, he romanticizes the idea of murder specifically in the context of Astarion's teeth against his neck. Sometimes, he thinks that it might be nice if, instead of dying of old age, he let Astarion feed on him until there was nothing left.

Morbid. Weird freak thoughts that are bad pillow talk topics. Instead of "I think I would be happy if you killed me", Iorveth cranes back to let Astarion gnaw harder if he wants. ]

You're sweet, when relaxed and blood-drunk. [ Maybe it helps Astarion feel less dead; maybe he feels more sensation that way. Iorveth combs through Astarion's hair, playing with stray flyaways. ] Makes me want to swallow you whole, I think.

[ In many ways. Cute aggression. ]
