The angels Zedekiah (white wings) and Baraqiel (gold wings) may be on a holy mission to protect humanity from the dark influence of the Abyss' demonic forces but that doesn't mean they don't make time for the occasional rendezvous...
Their fellow angels would be shocked if they found out, of course, so they are forced to meet in secret. Usually angels don't succumb to something so base as pure lust outside of the breeding chambers but Zedekiah and Baraqiel have long since given up trying to resist the draw they feel to one another and the pleasure they find in each other's touch.
