Demonic Devourer's Development

The day twelve of my imprisonment started just like any other. After I spent half of the night worrying if Aivena decided to be done with me this night after all, or was simply found and caught for sneaking out of Heaven, she reappeared out of nowhere in the morning, fresh and ready for the day. More so than me—no wonder. Her home in Heaven was much better for sleep than my cage, and her food was much tastier than the garbage she threw to me.

She looked at me as if thinking what stupid thing she was going to put me through this time. Except, maybe her eyes were gleaming a little strangely today.

"I came to a realisation that all this time, Devourer, I didn't know for sure your biological gender," Aivena said, coming up to my cage. "I assumed you are a man, but I never saw anything to confirm it. Your genitalia, as far as I can see, are void of any reproductive organs at all."

For a moment, I just stared at her blankly as thoughts clicked in my head like cogwheels. Then I grinned.

"Oh, you want to see my dick? Then why don't you show your boobs first, so we'd be even?"

Aivena scowled at me, but I didn't miss the way she bit on her lip, because I was looking for that reaction. It could've been a gesture of annoyance, if not for a hint of a smell I could scent in the air with my sharp nose.

"Don't try my patience, Devourer." She pointed her finger at me in an unspoken threat. "So what? From what I heard, demons aren't genderless. Are you a man, a woman, neither?"

"I'm a man, through and through. Just look if you want." I morphed my dick out of my armour, together with a pair of testicles. I made them look big and monstrous—but not too big and monstrous. It had the size that was a little too big for Yvenna (though she seemed to find pleasure even in pain), but just the right kind for Rosha, and ridges on it she liked quite a lot. It was already erect, too—I could morph it that way, and it didn't matter if I was aroused or not.

"Nice, isn't it?" I took my cock in my hand and gave it a slow, deliberate pump. "Does it make you want to suck on it?"

For a long moment, Aivena's eyes just stayed down there as she stood silent and enthralled. Then she wrenched her eyes to my face and gave me a look of disgust. "I should call myself lucky that you only now decided to descend to the insults of that level of distaste, Devourer. But since I went in this direction, I will explore it until the end. Hmm… I wonder how sensitive these parts are compared with the rest of your body. I assume you kept them hidden for protection."

Oh, I didn't like where she was going. When Aivena raised her finger, I immediately morphed my genitalia into my body, and not too late.

"Shock!"

I grit my teeth, but the spell, weakened by my orichalcum armour, didn't hurt me much. Especially after I got used to stronger ones. And Aivena's visible annoyance at my dodging was always a balm on my soul.

"Stand still, Devourer. I can't conduct the experiment if you will just dodge."

"Are you insane? Why would I just let you electrocute my dick?" I snarled at her. "It's bad enough you electrocute ME!"

"Because if you don't do as I say, I will do something much worse." Aivena promised with smug assurance. She licked her lips. "Let me do what I need with your genitalia, or I will start testing the extent of your pain tolerance and resistance to necrotic energies."

Sometimes, a man had to suffer to achieve their goals. Sometimes, a man had to suffer more than they expected. My cock WAS more sensitive than the rest of my body. Its torture won't be pleasant. But Aivena sure would like it a lot… I could already scent it.

Plus, necrotic energies were nasty, too. Indescribably so.

"Then show me your tits, Aivena." I leered at her. "A reward for good behaviour, eh?"

"Shock." After I shook off the voltage, Aivena sent me a condescending look. "Don't forget who's in a cage here, Devourer. I won't degrade myself for your amusement. Get it out, or the next spell I throw at you will be 'Wracking Ray'."

Yeah, that was necrotic energy. Unlike other, elemental energies, that one had… a special unpleasantness in it. Well, I tried. I lost the battle… but made a step towards winning the war. I morphed out my cock.

"All of it!"

With a tsk, I added the balls and crossed my arms over my chest, staring straight at Aivena with challenge in my eyes.

Instead of going straight to the cock and balls torture, she took a moment to just look me over. Her eyes stayed on my member for a few additional moments before moving past it to my legs and finally raising them to meet my gaze.

"Great. Now stand still. Let's start with minor stimuli…" She raised her finger with a gleam in her eyes that had nothing to do with research and science. "Shock!"

It hit me straight where it hurt. I didn't hold in the hiss of pain, but I kept standing still despite the urge to just hold the wounded parts and keep them safe. My eyes never left Aivena's, and neither did hers leave mine.

She licked her lips. "Hmm, you certainly show more reaction this time than to the 'Shock' before that, Devourer. Very interesting. While you can freely morph your body, it seems that some parts of it are rigid in their characteristics, which include sensitivity.. But I wonder if your penis is just as sensitive when it comes to positive stimuli… And whether these testicles can produce sperm."
