Isaac felt some warmth inside him from the demonic cum as it drips from the sides of his mouth. He felt disgusted as he could taste the demon’s foul, salty seed, having came in his ass and through his entire body. Isaac felt sore from that, especially at his rear where his hole seemed to be agape from the melting. It looked like it wouldn’t be closing some time soon as the seed slowly oozed out of it.
As Isaac stood up, he could feel the corruption settle in his body and spread, trying to change him as much as it can. Isaac could feel something grow on his head. His head ached as he rubbed his temples, trying to fight the pain. His back started aching as well, pangs of pain spreading from the top to the bottom of his spine. His hands and feet were in pain, too, causing him to kneel and grovel.
“Nggaaah!” Isaac screamed in the empty hallway as a bump grew at the bottom of his spine, just above his buttocks. His fingertips and toetips grew into claws capable of slashing through flesh. His teeth sharpened, giving him a razor-sharp grin that could incite fear in others. On his head were two caprine horns, similar to those of a ram.
Once the pain died out and Isaac was no longer paralyzed, he sighed and slumped onto his side. He felt exhausted, unable to gather the energy to continue forth. All he felt was his body telling him to rest. Yes, that might be all that he needed… his eyes felt heavy as he was quickly fast asleep from exhaustion.
