You take his hand and find yourself transported to another hellscape, at least that is what you must assume it was. A dark labyrinth with a void above as he guides you through the corridors you can see the people in cells and rooms and various open spaces being tortured in horrible ways. Their skin and body were taken apart only to be put back together, there were blood orgies and cannibalism and demons of various shapes and sizes. You weren't afraid though as you walked through the corridors you felt your own demonic form take hold as you grew and shifted, horns brandishing themselves as the beast of you followed after your boy. Eventually, your hand was replaced with a cock as he brings you to an open space where you can see around you several other demons. "What are we doing here?" You ask, the boy glancing back at you. There was that coldness in his eyes that you don't seem to notice again as he gestures to the symbol that had been emblazed upon your shoulder in cold blue fiery hues.
"You gave yourself to Niflheim, and now your here to gorge on more of hell." He stated as he let go of your cock and stepped back to watch. You were confused at first, but there was some kind of instinct that was guiding you now. As demons lept forward at you, you begin to fight back. Throwing them to the ground as well as catching them with your cock tentacles. They don't seem that interested in fighting though, more in sexually assaulting you. Some of them manage it when they are caught by your cocks, their dicks being pushed into the urethra openings, but it begins to go further than that. They are fully pushing their bodies into your cocks and you groan as you can feel them filling your urethras, the oversized cock tentacles beginning to suck them in as you experience a new form of pleasure. Slowly voring these demons now through your many extra dick appendages.
As you begin to consume more and more of them your own mind becomes more and more demented, "son..." You whisper as your prime cock pulses and you drift closer to him, "come here and show your Father how much you love him." You say with a snarl, your mind is getting darker and more twisted as you consume the demons more freely. They seem to be quite happy and content being devoured by your many cock tentacles. The prime cock had taken on that equine shape once again.
