It means this

Andy began to realize the horror he was finding himself in as his cock continued to twitch and pulse as Thalia stood there watching. His cock started to relax a little before it stood straight up in the air, still pulsing but almost as if it was waiting for something.

"I see, it is ready," she said with a wicked smile before she gently petted the head of his cock, which seemed to lean into it like it wanted to be touched. "I know, Andy here has mistreated you for so long. I want you to show him what true pleasure is. I want the pleasure to consume him, I want it to corrupt him, and drive him mad. Tear his soul apart with your orgasms. You no longer need his permission."

"What are you doing?" Andy asked, unsure of what was happening.

"I know, he still thinks his foolish questions matter," Thalia said still talking to the penis. "Show him what you can do."

Andy's cock seemed to nod at her request before he began to feel this strange sensation building within his cock. It was a tingle, almost an electric feeling starting at the tip and flowing down his shaft and into his balls. He could feel his cum starting to move around, almost like it was bubbling as precum began to foam from his urethra.

"What's happening?" He begged as he watched his penis start to grow, becoming longer and thicker.

His balls began to grow as well, stretching as his enchanted cum seemed to multiply inside him before this blue glowing aura surrounded his sex organ. It felt so good but Andy was too afraid to enjoy it as he no longer had control of his own sex organ.

"Please, I beg of you," he said to Thalia again. "I'll do anything, just please give me back control of my penis!"

"Foolish mortal, when I'm done with you, you'll beg me not to," she said with a coy smile. "Go ahead, Baby, you've earned it.

Andy's penis, now at least a foot tall and 3 inches thick, stood there motionless, dripping little beads of precum as Andy lay there in horror, waiting for whatever was going to happen. His heart was racing in his chest as he watched his glowing giant cock with anticipation.

"Oh, it's such a tease," Thalia said, sitting on a chair in the corner of the room, watching with excitement in her eyes.

Suddenly, Andy's penis started pumping like it was being fucked inside an invisible pussy. He let out a scream as his cock moved on its own, pumping harder as he let out a moan, unable to deny the pleasure. This grotesque-sounding squishing noise filled his ears with every pump as the room began to smell of sweat and sex. His precum was pooling on his pelvis as his cock continued to pump over and over. It almost seemed to be cartoonish in the way it moved and bent like the laws of physics no longer applied to his sex organ.

"Oh..... oh fuck!" He blurted out as his penis continued.

"Doesn't feel so good. You are going to cum so hard Andy, and there is nothing you can do to stop it. And then, when it's done, if it wasn't to cum again, it will. You are no longer in charge. If your Mom or Sister comes home and walks in, it still won't stop, and they will be **** to watch in horror before your living cock soaks them in your cum."

"Fuck, no, I can't......"

"You can, and will. Remember, ****!" Thalia chuckled at her magic as she watched his penis pump harder as she breathed in the smell of sex in the air. "I love that smell, all the different bodily fluids, mixing together, filling the air with that delicious scent. It makes me so horny just thinking about it. I would love to take that cock for a ride....... she said before she froze, a look of shock on her face that Andy noticed before she looked away. "Anyway, that won't happen, now, are you ready?" She asked before she waved her hand, creating something in her hand that looked like an umbrella.

"Oh God....... I'm gonna....... it's too much...... fuck........... FUCK!" Andy screamed as his cock suddenly burst, sending gallons of cum up in the air, splashing against the ceiling, and raining back down on top of him.

He closed his mouth, spitting as he tried not to taste his own semen while his enormous penis continued to empty his balls. He soon gave in and he knew she was right. This was a level of pleasure he didn't know was possible as the orgasm rippled through his body, bringing him to a level of euphoria he never knew he could achieve.

"I...... wow!" He said as his mind began to drift.

"You see, you know nothing of pleasure mortal. Your cock will show you, whether you want it or not," Thalia said with a grin before shaking off her umbrella and closing it. "My my my, what a mess," she said as there was as her feet were at least 2 inches deep in cum that had flooded the room.
