Until you drop(+18)

To start with, Kurayami had to begin the training sessions first. It was best for them to be to the point of exhaustion so that they would recover faster from the sessions with him.

Rebellion, Submission. and Ophis were with him as he rested on the head of Xargomoth. He was looking down at the current fights he had set up and was seeing that it was going well.

Ophis crossed her arms as she stood on the right horn of the demon. If she was wearing a cape it would make her look like a caped hero. Kurayami shook the idea out of his head before Ophis asked him the important question.

"When will you start fucking them?"

Kurayami who was resting his head on Submission's lap while Rebellion was giving him a shoulder massage looked up at her.

"When I feel they are about to drop from exhaustion. Their exhausted bodies will improve the best in that state."

Submission massaged the sides of his head as she looked down at the fights.

"Master, who do you intend to start with? They are all doing rather well."

He already had his two targets.

"Esdeath and Raynare, they have lasted 24 hours already against Castiel. They have kept their Balance Breakers going for that whole time."

Ophis looked down at the two of them. They were locked in a spar together against Castiel who would fight with light and shadows in one. Lightning coursed from his horns to his wings making him even faster.

They both use all of their skills, sacred gears, and lineages to do their best, but Castiel's might was far too great. He was even holding back, but it was still him showing his domination over the two of them. Despite that, they were still going.

It was close to 25 hours, and they were about to collapse. Only that Castiel kept pushing them just as Kurayami wanted. Xargomoth looked at the two of them and praised them.

'For how weak they are, they hold.'

"Weakness is a matter of perspective. You in this world are unbeatable, in Hell you are weak."

'You are correct.'

Kurayami stood up and looked at the rest of the fights going on. Akeno and Shalltear were both wearing their armors and had their spears as they were locked in a spar against each other.

They used the full force of their magic and skills, but Akeno was not the strongest for nothing. She had even started to copy Shaltear's tear magic and she even made a variant of Vermillion Nova that was even stronger.

Shalltear on the other hand was made for single combat, but she was facing a total monster. She only held on because she had been drinking Kurayami's blood regularly.

Ophis nodded every time she saw how Akeno could do everything at once.

"She is a monster Kurayami. Like you.

Rebellion felt it was just as expected.

"Master's twin must measure up to him."

Kurayami saw she was not getting enough stress.

"Ophis, send in a Heavenly Class snake for both of them. This is too easy for them."

"On it."

She gathered a ball of her aspect and tossed it down in between them. Akeno and Shalltear stopped training when a giant cobra rushed at them. It was 20 meters long and fast.

They both started to work together against the Heavenly class snake, but the pressure was real. While they got busy with that, he turned to Tyrant who was showing how unrelenting dragons were.

Grayfia, Lavinia, Natsume, and Annabeth were proving his name Tyrant was well earned. Nothing they threw at him was slowing him down even when they encased him in ice he just broke through it.

Lavinia's Balance Breaker was in full effect, causing a continent-scale ice storm that only targeted her foes. Even with that, the dragon's natural heat kept him in the fight despite him facing his supposed weakness.

Grayfia was using the storm to boost her ice magic to keep Tyrant restrained. She created gigantic ice pillars, blades, and even lower the temperate further. All to no effect as Tyrant just kept coming.

Natsume was riding on Griffon's back as he attacked with cursed flames and the wind. This was training for her as well as being in such a cold environment was making her shiver. As for Annabeth continued to produce different weapons and thread to try to tie him up as she was the front liner.

Even at her best, she could barely hold back the strength of the dragon even if she used Celestial Bronze metal strings. It was thanks to Lavinia and Grayfia that they were still in the fight as Tyrant was a monster in combat.

As for Walburga, Latia, Zesshi, Artemis, and Kuroka, they were fighting with Aurora who used her metal fur and skin to tank everything they threw her way. Only Zesshi with her death magic and Kuroka with senjutsu had much hope to harm her.

Latia pushed her time magic to the limit to slow down Aurora or speed up her teammates to keep up. Aurora was huge, but she was quick on her feet. She could even backflip so they were stuck with a living piece of metal that had the agility of a spring.

Artemis and Walburga tried their best to keep firing magic and arrows at Aurora as their max output. Artemis's arrows hit with the force of a ballistic missile, but all of it just bounced off.

Only Kuroka could consecutively land some minor damage to Aurora's insides, which lasted less than a few seconds. While they did that, Amaterasu and Nyx were facing a foe that they could barely see move.

Added with the fact that the horse would head butt and kick them around like ping-pong balls in the time they took to react. Even sunbeams from Amaterasu and her well-placed sword swings would miss by a hair's breadth and the giant expanse of shadows that Nyx used could not restrain him.

It was like the shadows gave way as they were both in their true divine forms. Amaterasu looked like the sun had given human form while Nyx was the night incarnate. Despite working together, Bliz was still faster and stronger.

Kurayami saw how Castiel swatted both Raynare and Esdeath to the ground causing them to collapse out of it. Blitz used his max speed and landed numerous head butts and kicks on the two goddesses making them collapse as well.

Blitz just basted around him with lightning that caused the girls to short circuit like a fish. Aurora did the same and ended her fight while the snake caught both Akeno and Shalltear. Kurayami raised his hand to stop the spars.

"That is enough."

Most of them dropped to the ground exhausted as they had been pushed to their limits all day. Even Shalltear who was undead and should never tire felt exhausted. They all gathered around Kuryayami as he came down from Xargomoth with his helpers.

Kurayami was proud of all of them.

"You are all made some decent progress. The gravity in this place is making you use more magic to stay up, so keep up the good work. Has anyone noticed anything different?"

They all looked at each other as they did not see anything. Akeno however was the first to notice.

"Nyx got stronger the most didn't she."

Kurayami was glad she figured it out.

"This whole day for her was a way for her to put the energy I gave her to use. She even managed to make great progress which is why I am now going to begin. Raynare, Esdeath, you look the closet to pass out. You two are first."

Hearing that he choose them first made both girls worried. Raynare raised her hand to beg for it to be another time.

"I am too tired."

He shook his head as he picked them both up.

"That is exactly why this is the best time to do this. Girls this will take a minute and I will be done with these two."

Ophis shook her head as she translated.

"Time distortion in a time distortion place. He will last days with them."

Both Esdeath and Raynare tried to struggle, but he had already teleported to his room. He tossed them gently on the bed and saw they could not move a finger to stop him.

"Sorry girls, you will see why."

He snapped his fingers and removed their clothes and replaced them with some sexy lingerie as he flipped them to their backs next to each other. The linger he choose was a black one for Esdeath that exposed her breasts and privates.

Raynare wore a blue one that did the same to explode them to his eyes. They had never felt this embarrassed before, but not being in control did that. He placed his hands on their thighs and felt them tremble.

They were sore beyond measure and drained of any ability to resist him.

"I always wanted to do this."

Esdeath tried to get him to stop though.

"Wait! Not like this."

Raynare nodded with fake tears in her eyes.

"Please, don't. I will be a good girl next time."

He just gagged the both of them to keep them quiet. His hands had been running up their thighs, but he never touched their privates. He saw how both girls started to try to squirm, but it just caused their vaginas to twitch for him.

He placed his hand on the both of them causing them to moan.

"What about this?"

He slid his pointer fingers inside both of them and felt how different they felt. Esdeath was hot, tight, and yet cold at times. Raynare was equally tight, but her insides felt softer.

At the sudden penetration, both of them screamed into their gags. He started to pump with his hands into both of them to get them as horny as possible. His thumbs brushed their clits making them get hornier.

Just as they were about to orgasm on his fingers he pulled his hands out just before. He pulled his cock out and got between Raynare's spread thighs. She could not even close them herself.

Just as she started to curse his name in her mind for the denial of her orgasm something huge spread her wide open. When his cock head hit her cervix, her eyes went wide open as she moaned. Drool left her mouth as she moaned like crazy at the hot feeling in her core.

As for Esdeath she saw the whole thing as he stuffed his cock in her best friend. He grabbed her leg despite her feeling sore and in pain and put her on top of Raynare.

They looked each other in the eye with shock, but Kurayami was not planning on going easy on them.

"You might be sadists, but I know that in every sadist is a masochist."

He spanked Esdeath making her squeal, but he was not going to ignore Raynare. He started to thrust into her vagina and she quickly felt the power running through her body. Even his precum was enough to make her muscles and body recover.

''WAIT!'

"No."

He ignored her as she wanted to be on top, so he penetrated her hard and deep. Esdeath heard that sound and knew that Raynare was getting railed. She could not even move and was stuck looking at her glazed eyes of Raynare.

"Can't forget you can we?"

He pulled out of Raynare which made her whine. She wanted him to keep going, but Raynare saw the same thing Esdeth saw. She heard a quick slap and the dark blue eyes of Esdeath glassed over.

'AHHHHH, YES!'

He grabbed her hips and he started to drive into her core enjoying the strange feeling of contrasting temperature. It was enjoyable, but he was more used to the extremes of Ophis. That girl could make it as hot as the sun or as cold as the void.

He shook his head to get the idea of Ophis out of his head making her laugh.

'Do I feel that good?'

'YES!'

At that moment he pushed deep into Esdeath as he felt the temperature of her vagina plummet. He came into her womb making her scream as she felt the powerful dragon essence in his sperm spread to her whole body.

She felt that her exhausted body started to heal and get stronger meaning he was right. He pulled out and thrust hard into Raynare making her scream.

'AHHH, he is cumming, INSIDE ME!'

He removed both girls' gags as he pinned them together.

"That is just the start."

He started to thrust hard into Raynare as her moans and screams filled the room. Raynare soon followed when he felt him start to finger her while he fucked Raynare. He had an endless libido and he would go forever and never get sick of it.

Only that his partners could not last as long as him, but that was to be expected. While he did that, Ophis sat down on a chair as she looked at everyone else.

"Don't worry, your turns will come. Unless you all decide to make it easier on him and yourself to just lose them in one big go."

They all looked at each other as most of them had known each other for years. Of course, Zesshi and Shalltear were not on that list, but they all had to make a choice. Akeno shrugged.

"We are brother's harem. Would it not make sense for all of us to please him?"

Amaterasu nodded.

"How about we give him a little reward? I am sure our likeness will be enjoyed by him. Artemis you are coming as well. No exceptions."

She looked a bit overwhelmed.

"Why? Can't I get to know him a little more?"

Amaterasu rolled her eyes at her friend.

"Don't be such a downer. He is going to claim you eventually. Speed it up and get stronger."

Artemis looked down and nodded.

"Fine."

Walburga was on board the whole time.

"FINALLY! Master will use my sluty holes."

Grayfia bonked her on the head.

"Language, but if master desires me it shall be his."

Kuroka also was fine with it.

"Kitten time."

Zesshi knew that Nyx tried and failed to get pregnant, but maybe she would get lucky.

"I am on board."

Lavinia looked at her belly and nodded.

"I want to experience it. Let's surprise him."

Shalltear looked at all the pretty women around her and as someone who was BI, she was definitely on board. Too bad Kurayami would not share even with his own harem.

Rebellion had waited long enough. She pulled on her sister's arm which made Submission nod.

"Fine."

Natsume and Annabeth both felt a little embarrassed, but they went along with the flow. Latia also agreed as if everyone else was doing it she might as well jump with them.

Ophis smiled as she communicate with Kurayami.

"Hear that, bring them in."

Kurayami teleported all of the girls onto the bed and they saw that he had bent Esdeath on the bed as he fucked her into unconsciousness. Raynare was on the bed spread eagle with cum leaking from her pussy.

They gulped as they saw that it was not easy to please him. He came inside Esdeath for the last time as he knew that the two of them had reached their limit.

"Well, time to start."
