Maybe she can tell him?

The next morning, Andy awoke in a cold sweat as his cock throbbed between his legs. He quickly noticed the tent pitched in his blanket and removed it to find his penis fully erect.

"What the fuck?"

Andy stared down at his cock, which was at least twice the size as it was before, but it looked different. The veins were green along with his foreskin. The tip was a deep purple color and green precum was dripping from his urethra.

"Shit, there's got to be..... wait, where's the book?" Andy said as he looked over and saw the book was gone. No, no no, it can't be........"

"Looking for this?" A woman's voice said before Andy looked over and saw someone in his room holding the book. "I see someone said Procedere too many times."

Andy was stunned by what he was seeing. She was stunning, sitting there with long blonde hair and a white dress that was practically see-through. Her tits were perfectly shaped, but Andy quickly looked away, trying not to stare, and that's when he noticed her eyes. They were a stunning blue but looked almost like flowing water and her ears were pointed.

"Who....... who are you?" Andy asked with his mouth wide open.

"I am Thalia, the author of this book here. And you thought you could play with sex magic, without consequences?"

"What.... no. I mean I just wanted......"

"What is it with you humans? Always looking for the next big thrill instead of just enjoying the intimacy," she said before she stood up and walked over to the end of the bed. "Look at your penis. This is what happens when you don't have self-control. Looks like it had already started to bond with you, but you were able to stop it before completion, but it still left something behind."

"Please, can you help me?" Andy asked looking up at her with pity in his eyes.

"Of course, I can, but it doesn't mean I will," she said with a grin as she opened the book back up and began to look through it. "Maybe I'll invite it back so it can finish transforming your penis into its new home."

"What, oh God, please don't!"

"Why not? It will feel so good, and then your whole life will be mind-numbing pleasure."

"Shit, that sounds..... no, please help me."

"What's in it for me?"

"Please, Thalia, what can I do?"
