The ceremony was, of course, disgusting. All of Kar's rituals were odd, but the one that Brian was performing was one of the rarest and most powerful.
Kar may not have been bad, as half-demon demigods went, but he was still part demon, and so his rituals could be a bit uncomfortable for the squeamish. There was chanting, of course, and prostration. But Brian felt very self-conscious as he smeared his own sweat, spit, blood, and cum on the statue's phallus. He became even more nervous when the stone penis began to lengthen and grow, becoming erect. Despite his nervousness, his shame, and his disgust, Brian continued with the ceremony - his desperation, and his burning desire had overshadowed all else.
Brian finished anointing the statue's cock, and placed his mouth on the thick stone shaft. Nothing happened. "I knew it wouldn't be that easy," Brian thought to himself. So he began to suck, and to slide back and forth, giving the statue's rock-hard dick a first-rate blow-job. As he did so, he could feel something churn deep inside the stone phallus.
Then, fire entered Brian's mouth. He tried to scream, but his mouth was so full of the statue's giant cock that he couldn't do more than whimper. The heat spread throughout his body, which writhed in pain, even as part of him was directing his mouth to suck more and more fire out of that glorious stone penis. Brian's body became firm, as his weak flesh hardened with dense muscle. He grew taller and thicker, as old bulges returned, and strength suffused his body.
