[ He's always hated the feeling of someone on top of him; it makes him feel pinned down, trapped. Iorveth doesn't make him feel that way. Astarion finds that he actually likes the feeling of Iorveth's body atop his (and beside it, and under it). He never puts enough weight on Astarion to make him panic, and his body is a pleasant warmth enveloping Astarion's. Like many things Iorveth does, it makes him feel cherished. Something he would've considered an impossible concept months ago.

Astarion cranes his neck, both to allow Iorveth access and to signal that he does, in fact, like it. Anything surrounding his neck was once controversial, too. The feeling of Cazador's fangs in his throat wasn't just unpleasant because of the outcome; it had hurt, and he'd felt so scared, so cold. Iorveth's mouth on his neck is nothing like that. He wishes he could replace the marks Cazador gave him with the indentations of Iorveth's teeth instead. ]

My little vampire, [ he coos, amused at the reversal of roles, and less amused at the prospect of Iorveth's immortality not working out, ] you're ridiculous if you think I could ever care for anyone after you.

[ He never cared for anyone before Iorveth. It doesn't seem possible to care for someone after him. ]

My life was endless darkness until I met you. [ And it will be endless darkness after him, he can only assume. Very healthy. ]
