A massive, knotted, double-headed black peen

As your essence ascends from the underworld, purple and black sparks rage through the air above the Demonstone until they reveal your steaming figure. You watch your worshipers fall on their knees in reverence to your power. With a light nod, you call the priestess to your engraved pedestal. The female Gryphon moves swiftly, with countless clanking bones decorating her mortal body, kneels between your legs and extends her arms towards you. You allow your gargantuan penis to extend from its shaft and flop into her cupped hands. Ceremoniously, she stands up, firmly gripping your heavy length that towers up to her head with both arms. She shouts to her followers and they respond with an eerie chant, locking their elbows while kneeling and performing a circling movement from their hips. You remember the first time a mortal had summoned you. At first, you were surprised, puzzled to be able to walk the sacred grounds you had been banished from. It turned out that the priestess had sold her soul in exchange for an ancient artifact, a shard of the Tainted Orb itself. With the sacrifice of a living creature, you and your kind could enter this world once again. But you were always the only one who was summoned, up to this day. "John!", she shouted, the crowd echoing your ancient name aggressively. You know that, if the cult's plans should succeed, you will be highly regarded among your kind, praised by demons and living creatures, perhaps even by the Fallen herself. You let out a guttural grumble as the priestess licks across your erect length, rubbing her silky body against the sensitive skin. Most of the elected die during the brutal intercourse. The few who survive having sex with a demon, sacrifice their bodies later, when your sons and daughters, Succubi and Incubi, tear out of their husks. The priestess rubs her pussy against your slick penis, moaning while the chant of the congregation grows in intensity. Three loud moans, a growling from your throat, and a name suddenly break the gloomy ceremonial sounds as the priestess reaches her climax.

"Dhal-Akhar!"
