"I’ll do it," I said. "I’ll help you seduce the Queens of Light."
"Excellent. I thought you’d agree."
She began to strut toward me, hips and tail swishing(a tail I somehow hadn’t noticed till now), her breasts jiggling to the rhythm of her steps.
"Before you begin your mission, I will grant you powers to help you on your journey. Your path will be long and arduous, but these powers will assist you in times of need."
The goddess shrugged her shoulders. Her outfit puffed open and disappeared in wisps of black oily smoke.
And with her clothes the terrain changed, we were teleported to a cave of some sort as water hung about my knees.
She was naked now, golden pubic hair and light nipples fully exposed, bare feet splashing in pools of cave water.
When she was so close that her toes touched mine, she smiled, showing pointed teeth. And a completely different demeanour.
She knelt. With one pointed finger, she pushed me down so I was lying face-up, staring at the stalactites.
The goddess straddled my legs. I could feel the soft flesh of her legs pressing against my thighs. My cock was fully erect just from the sight of her.
She grabbed my cock. Her fingers were warm and had a snakelike texture. I moaned.
"Once the ritual is complete, the effects cannot be reversed. You will be infused with demon magic, as your body cannot handle light, for the rest of your life. This is your last chance to say no and return to the land of the dead."
"I want this."
"Then let us begin."
She squeezed my shaft. Her tail slithered up between my legs and began to prod and massage my balls.
"Repeat after me. I swear fealty, in body and soul, to the Demon King Thallafax ..."
I repeated her words. She told me more words to repeat. I repeated those too, though I don’t remember now what I said.
At that point I was so horny I probably would have vowed to sign all my personal possessions away, along with my soul.
As I repeated her words, she continued to pump my cock up and down, occasionally bending over to dribble saliva onto my shaft. Wherever her saliva touched flesh, my cock tingled.
"It feels really good," I whimpered. "I’m gonna cum."
She leaned over me, looking into my eyes with yellow pupils. She grinned, exposing two white rows of sharp teeth.
Then, at last, she opened her mouth, and, bending over my dick, she—
She bit down hard.
"AARRRGHHHHHH!"
Sharp teeth sunk into my manflesh. The pain was unbearable. White hot light flashed before my eyes. It felt like my brain was boiling. I screamed a scream that lasted a thousand years.
I blacked out.
When I woke up, the goddess was back on her boulder, looking down at me with triumph.
She waved her hand. The cave wall near me rippled and turned into a mirror.
"Behold," she said. "Your new body, enhanced with dark magic. You are no longer a mere mortal. You are a warrior and servant of Demon King Thallafax. Tell him Selene says hi."
I stood up and looked at the mirror.
"That’s me?"
At first, I couldn’t believe it.
My jaw had filled out, my teeth had become straight and white. My receding hairline had filled in, replaced with moist, well-groomed hair. My acne scars and chest deformities were gone, along with any excess body fat. I had perfect posture, six-pack abs, pecs like plate armor.
Then there was my cock. I had gotten a massive upgrade. An iguana was dangling between my legs. Even flaccid I was seven or eight inches long.
Below the tip of my new cock was a dark pink mark. It was shaped like two rows of sharp pink teeth.
"That is my brand," she explained. "Also known as a ’Mark.’ That’s why I had to bite you. Marking a human infuses him with demon powers. The Mark changed your appearance, but it also did a lot more. You have developed powers."
"What kind of powers?"
"You shall see," she said. "Many of your powers are still in a latent form. You shall learn to develop them with experience and training. The more women you seduce, the stronger your powers will become."
"Kind of like an RPG."
She ignored this.
"For now, it is safe to say that women will find you far more attractive than they did before. But this is not due to any kind of magic. It is simply the force of your physical attractiveness and charisma. Demons, contrary to what humans will tell you, do not like to cheat ... When you seduce women, the method must be pure."
"Wait," I said. "One minute you’re telling me you want me to seduce the Queens of Light and now you’re saying it has to be pure?"
"I said the method has to be pure, not the act itself."
"Um ... that ... makes no sense."
Selene sighed. At least I’m assuming that’s what her name is.
She uncrossed her legs, showing me a considerable amount of naked thigh, before crossing them again and flipping her hair.
"Just listen," she said. "Once you have a woman seduced, you can do whatever you want with her. But she must agree to it out of her own will. That is what I mean by pure."
"Ah I get it," I said. "Tricks aren’t allowed. I’ve got to seduce her fair and square."
"Right. You are forbidden from using violence, drugs, blackmail, or anything that would cause a woman to sleep with you against her will.
You must corrupt her fairly, by using your charm, and—equally importantly—leveraging her own desires, interests, hatred, and fears. Do you understand?"
"Wouldn’t have it any other way," I grinned. "Even wife-stealers have codes of ethics."
"As do demons and gods. I think we’ll get along just fine."
Selene clapped her hands.
"On your way then. Your first task will be to seduce the Queen of Windmoor. Already her husband’s ships are preparing to assault the coasts of Demon King Thallafax’s kingdom. You must seduce her and convert her to our cause before the winter ends and the ice sheets melt."
Before I could say anything else, she picked me up, carried me deeper into the cave, and threw me head-first into a swirling portal of red light.
