Rex tried to recreate what the leader was doing by just trying her hand hot. The smelling of burnt flesh could slightly be smelt.
"I want to learn." Rex thought.
Then he got a notification.
"Burning Hands Technique"
"Learn how the current ruler is able to heat her hand and the Technique will become yours."
Rex was surprised by how simple the quest was. He first tried to allow his Qi to heat up his hand. That was indeed a part of the secret, but it would not burn any flesh.
Rex pointed to the leader of the single virgin.
"Help her make those sisters regret doing such things."
The leader went over spreading the cheeks and revealing the pussy to Rex.
In that moment, Rex felt a chill in the air. When he looked back down, he could see ice forming on the first sister's asscheeks.
"Such power."
Rex got another notification about her Technique.
"Frozen Hands Technique"
Rex knew that this was either something they were born with or a very old technique passed down through the ages.
The sisters' leader began to stick her fingers inside the asshole of the first woman.
"HOT!"
The sister screamed.
"Spread your inner muscles out."
The sister was not doing it.
Her leader formed a fist. By heating up her knuckles, the asshole began quivering. Her pussy was trying to protect its inwards by releasing juice.
"Shameless."
She forced punch knocked the hip out of place. Thus the first sister could not effectively get any defense up now.
"Demon King, Shall I shove this dirty whore unto your majestic cock?" Her leader asked.
"After each of them is like that." Rex replied.
The current scene kept going for another hour until all four of the sisters were begging for Rex to enter inside them.
"Now then, what do you four want to do?" Rex asked.
The four sisters looked straight at Rex's groin area. No words had to be spoken as they were ready to let themselves be killed by whatever was inside Rex's pants.
"Such bad women." Rex thought.
"No words just staring at a massive cock inside some pants." Rex said.
The sisters were embrassed but the others knew that there was nothing that they could do.
The sisters got to crawl to Rex. This was supposed to be a good day but they turned it bad.
"Such is life girls. One moment, you enjoy a decent thing. A bad decision causes each of you to lose everything. Tell me, how should you repay my generous offer from before?" Rex asked.
"By raping us." The first sister said.
She was the eldest and not the first one to get her hip dislocated.
"Killing us." The second sister replied.
She was the first one to get her hip dislocated.
"Placing us on tables for each and every Demon to play with us." The third sister replied.
The fourth sister watched and listened to what her sisters had said. They were only thinking of themselves and not the entire underground.
"Your Majesty, I believe it to be fair to force us into submission in order to rule over the demons here." She said.
The others knew that her answer was indeed the right one. They did not want to be the one to actually say it.
"Do you three agree with her or disagree?" Rex asked.
Instead of agreeing, a silent eerie look came on each of the sisters. They had to say an answer but honestly did not want to say the right one.
"Your silence tells me that each of you already wanted to say that but did not have the gull to actually say it."
Tears ran down their faces because they wanted to give an answer and could not.
"So, you three. Enjoy the answers that each of you gave." Rex said.
The fourth sister instantly replied, "I was wrong please do not hurt them."
This angered Rex. He truly could not fathom why they were so against him.
"Continue their torture."
The two ruler dragged two of them out each.
Screams of terror and pain vibrated the underground.
"You three. Either make me happy or I am going to start a slaughter." Rex said.
"Then slaughter is my choice." The first one said.
"Then start by killing her. I do not want you angry, I want you cheerful." The middle one said.
The two outer ones wanted to beat the middle woman up.
"You?" Rex asked.
"Slaughter." She replied.
In that instant, a blood mist appeared and the two outer ones disappeared.
"Come suck my dick, if you fail another blood mist will appear."
She rushed over and began to effectively suck the dick and make it where Rex could squirt his substance on them.
After five minutes, Rex patted her head.
"Good job."
This simple praise, would get her to become a powerful Demon Lord ruling over territories.
The child came over and looked at Rex's hard dick.
"You are too young. If you want to watch, go on ahead." Rex said.
She got to watch as the other girl began to kiss Rex. This was not only for her to know who her Master was and is, but her to showcase her nudity and sexual prowess.
"Tell the other two to bring those screaming whores back in." Rex commanded.
She did just that.
The four sisters came back in partially frozen, partially burnt, and a hundred percent scarred for life.
"Any changes in your attitudes?" Rex asked.
Since he had calmed down from the other mistakes. He could slowly enjoy the questioning and answering.
"No." They all replied.
Rex felt that his good deeds were going in and out of ears.
"Fine. Allow every Demon to use their pussy and asshole as they see fit. When they no longer feel anything, rip out their spines. Bring me their mother, so I can give her new children so that way she is not lonely." Rex said.
The four sisters got sent to the worst city in the Demon Realm. Only after three days, did the girls finally breakdown and worry about their lives.
It became too late because Diablo ripped out their spines and sent them to Rex.
