"Your curiosity almost got you possessed Ilvir, and by an imprisoned lust demon no less." Isaac told him as Ilvir regained his bearings. "You are fortunate that my training as a holy paladin allowed me to purify you and strip the demon of most of its hold over you."
Ilvir sat up on the ground as he took this info in. "Are you sure of this? Is that what covered me in these.. unff.. nice crystals?" Ilvir tried to remember everything as he looked at Isaac his creator, and took in the sight of his powerful and attractive body.
"Yes my spawn, and if it were not for me you would have been fully gone at this point, but my spell has shrunk the crystals substantially although they still remain." Isaac told him. "The demon however should still be inside you, it's power reduced and you should not be in immediate danger of losing your mind at this point." Isaac turned around as he began to pull out the Lexicon again from his body with his vines to look for more information on the demon.
Ilvir was now exposed to his glorious creators backside, unable to do much other than take in the view of Isaac's virile balls and cocks which hung below an impressive ass. "Your lucky to have such a sexy creator Ilvir..." The demon Azaviel inside Ilvir whispered to him through their mental link. "Why don't you indulge yourself a bit Ilvir! You have made it so far into the dungeon already, a little... release so to speak would do you good." Ilvir wanted to protest but it had been some time since he had cum already, instead of the words he wanted to say to the demon inside him all that came out was a quiet moan.
Unaware of the horny Ilvir behind him slowly starting to crawl towards him Isaac looked over the Lexicon and spoke aloud when he saw more of it had been filled out. "Ah the book, Ilvir I should have a little more info on your situation here shortly." Reading through Isaac read that until the demonic possession from the crystal had been fully cleansed that the subject would slowly grow more horny as the lust demon inside him would continue its attempts to gain control. Interestingly as Isaac read the next page on the demon he began to grow slightly horny himself as he took in the instructions.
The demon soul (Azaviel) continued possession after simple purification.
If the demon inside has been subdued with a purification spell then simply cumming would no longer be enough. The seed of his host would have to be unleashed into a more powerful creature in a display of dominance. The demon inside would gain more control each time a dominant act like this is completed.
To facilitate this the demon inside will attempt to mold and persuade his host into a more dominant role as it makes its host more sexually aggressive.
The only remedy for this until a complete purification can be performed is for the host instead to be forced into a submissive sexual role and claimed by one stronger in bed.
Isaac was sweating as his own arousal had increased. The only way he had at the moment to aid his friend now was to breed his granite hole if he became aggressive and started to lose control. Isaac wanted to be upset that this was the only method but his erect cocks and growing smile said otherwise.
"Good new's Ilvir, I may have found a temporary solution to your problem you might like." Isaac said closing the book and storing it away inside his body once more. Isaac grew concerned at the lack of a response, worried that the demon has effected Ilvir so soon he turned his head around. Isaac was quickly shocked at the sight of a dazed, drooling, and erect Ilvir that was right behind his ass with a slight purple hue to his eyes.
