An offer is made

"Ooh, a bargain from a mortal. Interesting." Thalia said with a smile as she approached him. "What could you possibly offer me?"

"I dunno, I just.... oh God!" Andy's cock began to squirt out green cum which felt incredible as he bucked his hips.

Thalia backed away, watching his enlarged cock twitch with a smile. She was enjoying what she was seeing as she was an expert in pleasure and sex magic. Every time a mortal got a hold of one of her books, it always ended in a mess, but Andy had her intrigued.

"I'll tell you what. I will cure you purple pee pee here," she said with a chuckle. "Only if you give it to me."

"What? What do you mean?" Andy asked in a panic, not sure what she meant by that.

"I've been asleep for a few hundred years and I am bored. I want to write a new book and create new spells, and I need a test subject."

"Test subject?"

"Yes. I need someone willing to let me try my spells on their sex organ."

"That sounds..... what will it mean?"

"It means that you will experience pleasure that no other mortal man has ever felt. I will cast magic on your cock that will make your life feel like heaven. Now, like in all experiments, there may be some mistakes and mishaps, so to speak, but whatever damage is caused can easily be repaired, and it won't happen often. In return, I will cure your sex organ of its current issue and also show you more of the spells I have already written."

Andy couldn't believe what he was hearing as she ran her fingers along his inflated penis, still dripping green slime as his eyes rolled into the back of his head and he moaned at her touch.

"And if I say no?" Andy asked stupidly.

"Then I leave you and your penis to whatever fate becomes of the leftovers filling it right now. Could be pleasurable, could be painful, but I promise you, my way is much better. So, what will it be?"
