Vex sighed softly, inhaling Isaac's scent and glad to have him close. Liking that they had one another, that they had this time to come together. Whether sexually or otherwise, though he wasn't sure he would ever want to, or could ever, give up that madness that was intimacy between them.

"Promise. If I die, it won't be in front of you," he admitted, meaning it. He'd find a way for it to happen when Isaac wasn't there.

"Yeah, I am betting you love that," he said, grinning. He took a breath and then, a moment, he started to whistle. It was still there. He still had the siren's voice. Whistling in a voice that was supernatural and not human. Not in the least.

And it was meant to make him feel good. Not even sexual, but relaxed and content and happy.
