Power surged through Isaac's new body as he grew. The absorption of the earth elemental that contained Ilvir's essence had made Isaac's corrupted form even more demonic and lustful. His new body was massive at a bit over 8 feet tall now and built like a tank.
Panting ice crystals on the ground from his toothy visage Isaac's body grew warm with the inner fire of his arousal. His now larger icy member slid out past his metal loincloth as it grew in both size and more erect, dripping drops of glowing blue seed.
While the choker of purity managed to keep Isaac in control of his mind, his body on the other hand gave him so much corrupted pleasure he could not help but let out a deep moan as his lower set of demon hands grasped his aching cock.
Isaac began to lose himself to the act momentarily as one set of hands stroked his titanic member and the upper set squeezed his chest in rapture. The absorption of such a large creature had added equal parts mass and lust to his body as his balls churned with seed as they grew. The new huge rocky balls that hung beneath his legs rivaled the size of ripe melons as they pulsed with need.
Just as Isaac was starting to give into his inner beast, he felt a connection to the paladin he had absorbed through the elemental. He could feel Ilvir calling to him in his mind pleading for some way to escape and have his own body before he too gave into the pleasure. As Isaac had absorbed the human body that Ilvir used to inhabit he started to think of a way to release Ilvir from their connection, still stroking his enlarged cock all the while. Isaac moved his hulking body up as his bulky tail twitched in pleasure, moaning as every part of his larger body felt more sensitive as it contained the corruption inside him. Even Isaac's enhanced rump felt good to him as his thick tail worked to tease his puckered opening and swaying balls. It was then that he spotted the remains of the other earth elemental on the ground, it was still mostly intact but it seemed like it could be a good shell for Ilvir to inhabit. Grinning a toothy smile Isaac focused on pushing Ilvir's essence into his glowing frosty balls. Letting out deep grunts and groans as he worked himself over he aimed his giant cock at the empty shell of the elemental, hoping that his perverted idea would at least let Ilvir have a body. With the amount of corruption flowing through him the bliss Isaac's demonic form felt was substantial, now that he had a plan to help Ilvir he let himself get lost in the pleasure again. Furiously humping one set of hands now as he made increasingly monstrous noises in the cave, loving every moment of his well earned release. Just as he approached his climax his other set of clawed hands made sure to squeeze his glowing sack to squeeze out all of Ilvir onto what would be his new body. With a loud howl Isaac blasted what must have been a gallon or so of glowing seed to cover the construct, drooling icy spit down his maw.
As he came down from the high of release Isaac realized he could not feel the paladin's presence in his mind anymore. He looked down at the earth golem he coated with seed and watched it absorb into the rock and mud. The new body for Ilvir assembling into a slightly more humanoid form as an earthy maw began to form and a decidedly male cock grew. The new form impressive as it materialized but still not close to the hulking demon that Isaac was now.
