The grandmother looked at Rex with a new look. Since he undoubtedly had two different Demonic Powers. One of the two was what she was not expecting, she feared the worst.
"Sir, I hope that you are not trying to force a new type of demon." The grandmother said fearfully.
Rex was questioning why a new type of demon was being forced.
"Care to explain before you try to take my pants off. Or shall you be defeated by taking off my pants and reveal what you your trying to say?" Rex smiled evilly as he spoke.
The grandmother decided to undress and take her chance. The moment her outer dress touched the ground, Rex was stunned that she did not wear anything underneath and still had such strong breasts that held themselves up. Not only that they were quite the size as well, Rex guessed at least high level C cup or low level D cup.
When he gazed lower, he found that her pubic hairs were showing the man she loved and married. This was quite the surprise to Rex. That took a long time to not only nature, but to get the hairs to stay like that.
"Such pretty pubic hairs. How often do you truly work on it?" Rex asked curiously.
"I have not worked on them for thousand years before I was sealed." The grandmother showed her demonic smile as she spoke.
Rex was stunned. He did not think that such work could naturally be stopped. All of that was about to go to the back burner as she walked closer.
"Tell you what, if your pants do not come off. I can allow you to learn what the Demon Typing is. However, you will get her pregnant as well." She glared as she spoke.
Rex naturally began to grope her.
"Such big words for such a small woman." Rex said smiling ear to ear.
Although the woman, herself, was not small by height, weight, or any figurative means. She was small to Rex's Demonic Domain powers. He was not sure why he actually said that.
Moans began to erupt into the room. The grandmother could not take much of Rex's torture to her breasts. Once the scent of her love juice barely hit her leg. Rex began to touch her slit.
"Oh this thrill." Rex's Demonic Domain powers were screaming.
To Rex, this was more of a headache than anything. He did not know why his hands were moving and he was honestly completely upset that he could not control them either.
"Damn body, Listen to Me!" Rex screamed inwardly.
The Demonic Domain powers were currently too strong for Rex to control. He could control the system which was controlling his pants.
"Perhaps, this will work?" Rex thought.
"Woman, do you dream of a Demon King's raging dick inside your tiny pussy?" Rex's Demonic Domain powers questioned.
"Of course, any demon woman would dream of a Demon King's raging cock." The grandmother replied.
She transformed. Her true Demonic self was a Black Phoenix. This was no ordinary phoenix, this was one born from the depths of darkness and would constantly be rebirthed by darkness. As such, this woman would never truly experience death but just live a life without a mate ever so often.
The price to live with a mate was greater than most. She would have to birth a demon just like her. The stronger the male is, the better her chances of birthing a child. If she does not have a mate, all she has to do is redecorate the room she is supposed to live in.
While a strong mate is always good. She does not abide my normal laws. She is a Demonic Phoenix, if a man she desires can produce a strong child. She can get permission from her mate to birth another child. If the child is stronger, the duo can raise it together. If it is weaker, than death is the only thing awaiting that Chile.
"I do want your dick. Please ravage me." The Demonic Phoenix pleaded.
"Oh, pleading now are we." Rex's Demonic Domain powers said.
Rex bent her over and released his hands. A massive stream of Demonic Qi left the the Phoenix's birthing hole. Rex seemed happy. This was Qi he actually needed to strengthen himself.
He immediately sat down and cultivated. The Phoenix knew her Demonic Qi was strong. It was not strong enough for normal demons to cultivate with.
"Why are you," she stopped seeing that Rex was using that Qi to cultivate his normal Demonic Powers.
She was proud that her Qi could be used that way. She wondered if Rex would use her to strengthen not only her granddaughter but whoever he needed her to.
"Oh the thrill of having my pussy banged by a True Demon King." The Phoenix thought.
She sat down beside him. She helped him cultivate the weaker Demon King power.
She was truly regretful that he seeked out to strengthen himself first. The Phoenix knew that this was most Demon King's thinking.
Once the Qi got used up. Rex was left was wanting and did not want to make the Phoenix stay here. He also did not know if she would be willing to become a servant.
"I truly do not understand." Rex felt his heart become saddened.
The Phoenix understanding his look. She decided to call her husband in. When Fengbo entered, he wondered why his wife was in the form that they met in.
"My dearest wife. Why are you in that form? I thought you loved the humanoid form better!" Fengbo exclaimed loudly.
Fenggo and Fenggi both did not understand. To them, they knew there were a lot more things hidden away from them. The fact that the bird was truly the form of the grandmother. This helped Fenggo and Fenggi understand the crow form that Fenggo does.
"I am willing to help strengthen him and his wife. I cannot go without you and you cannot live without me. What do you plan to do?" The Phoenix asked.
Fengbo understood what his wife was saying.
"Of course dear. You have made me so happy over the years. If you decide to leave, than leave. If you wish to remain, remain. I have overburdened myself over the years. The only fix it to is death. I just hope that you do not die." Fengbo said happily.
The Phoenix plucked a feather the had the the hairy form of the mate. She had been able to pluck him from her life because their child was born weak and could not even use parts of her strength. This was not enough to make her cut ties with him.
She needed to know that he was ready for death. That this would be a way for her to continue life without dying herself. Since a Demonic Domain Demon King was willing to let her be a slave, she willing accepted it.
"Let us bury my husband before he dies please." The Phoenix asked teary eyed.
"Of course." Rex said.
A grave was dug for Fengbo. His life was rapidly falling away. Once the grave was dug, he smiled. He fell backwards of his own accord and died within the fall. He did not feel the pain of his body breaking apart on the ground.
Cries of sorrow, love, and never forgetness were shed by the Phoenix. Although she could rebirth him as a demon. She did not want to and allowed his body to help keep the planet strong.
