I woke up to find myself in a white room, similar to what you would see if you were taken to the god realm as a soul, but with the exception that I was in physical form.
'Where am I?'
When I looked at my body, I found that I was only wearing a frilly black bra and panties and that I had cat ears on top of my head, a cat tail, silver hair, and beautiful blue eyes.
"My wife, Amelia, you're finally awake." Isla said. "I had no idea that this world was a video game made by a developer from Earth, where you had previously lived before being reborn in this world."
"How do you know all of this?"
"I saw some of your memories when I came inside of you." Isla answered.
"I became the Beast Goddess because of the source you gave me, but why did you have to give me portion of your source?"
"I wanted you to be a demon so that we would be alike with us both being succubus." Isla responded.
I felt my ears and tail, which made me horny since it was an erogenous zone.
"Where are we, I thought your intention was to rule the world."
"For the past thousand years, demonic energy has been transforming those inhabiting the world," Isla said. "Every living thing that contained demonic energy turned into a demon after we had s*x."
"We won the initial conflict but ultimately fell short, but shouldn't you be dead by now since we killed you?"
"My body perished, but I didn't die as I entered the God Realm, became the Demon God, and killed the Beast Goddess to give you her source leading up until this point."
"Since you've succeeded in conquering the world and made me your wife," I said. "What's your next move going to be?"
"Not much, other than conquering your world and enjoying my time with my wife."
"Don't, I don't want you to harm my world in the same way that you did this one." With blush, I replied.
Isla responded, "Too late. The demons have already invaded Earth while we monitor them, but don't worry, I gave the humans magic and a system so that they have a chance, since it would be too quick and boring if we didn't."
"What about the other heroes, what did you do with them?"
"Sitara, the Warrior—or should I say hothead—is now Miyuki, the Snow Empress, who reigns over the snow women and girls and rules of over the Snow Region."
"What do you mean by regions?"
A holographic image of Earth with its many distinct regions appeared, and Isla moved her hand in front of it. "When the demons entered, they seized control of the land and transformed it into regiond that matched their element."
"Thanks."
"Since I'm your wife, there's no need to thank me," She began caressing my breasts.
"Mmnggh."
"Your are very sensitive."
"Stop, please continue on with what happened to the other heroes." I retorted, floating away before making a chair for myself to sit on.
"Fine, but tonight we better have sex." She sat down on a chair she had made next to my after pouting.
'Why did I have to become her wife, even if I'm used to this body by now?'
"Dorien, the light hero, is now Lilith, the Vampire Empress, who rules over the Crimson Region."
"Why a vampire?"
"Just wanted him to become a vampire, nothing else besides that." Isla answered.
"Alright."
"Leor, the healer, has changed into Auza, the Basilisk Empress, who co-rules the Poison Region with Albern, the shield hero, who has changed into Ivy, the Arachne Empress."
"You turned all the other heroes into empresses of their own race, but why did you make me the Beast Goddess, and your wife?"
"You don't need to know the reason I chose you to be my wife, so let's have s*x now." Isla made herself a bed out of two of our chairs and climbed on top.
"Why can't I be on top?"
"Because you need to be at the bottom since you're a woman." Isla Responded.
"But you're also a woman,"
"No buts."
I tried to escape because I didn't agree with her, but she was too strong and I couldn't even move her an inch.
We were both naked when she flicked her hand, so she formed a cock, inserted it, and then began thrusting.
"Mnnngh."
