Your secret's safe with him - Alastor would never in a million years confess to being this ferocious and feral in such a crude, sexual way in his right mind. That Lucifer gets to live to tell the tale is a privilege! Many other Sinners were simply torn to shreds by the fangs currently careful not to do more than puncture to elicit those perfect moaning noises, pitched high and low and hitting almost song-like notes.

When the song was interrupted with speech, Alastor snorted and licked at Lucifer's face to hush it, pounding deeper and harder to get those pretty little moans back. Shush that sass!
