Okay. That was definitely okay. It was still very experimental - not that Lucifer didn't know how to sin, but this was still his brother, still Gabriel. So he took it slowly, asking for Gabriel to open his mouth, sliding their tongues together, a catch of teeth on teeth.

Always gentle, because those were the rules he'd laid down, and he didn't expect Gabriel to release him from them. This was the reunion he'd been hoping for; not deceit and betrayal.
