Day one of training had been quite quick. Keiji focused on some arm training along with endurance as the group had to go up a mountain while carrying heavy equipment on their back. After taking a break from that, Keiji's next task was to do some training with Yuuto, who was teaching him about speed, reflexes and agility. His time with Akeno, which he also spent with Asia as a partner, was focused on trying to control his demonic power better. Rias helped him with the dragon portion, while the fallen angels and Ilulu were also there to help with massages and minor stress relief.
With all the muscle breaking work, the Peerage and Keiji's concubines went to have lunch. As an additional part of the training, Keiji and Asia were made to peel the potatoes by using their magic to shred the skin off as well as mixing ingredients by using their magic power as a rolling sphere.
After eating a healthy and well prepared meal, Rias offered a nice dip in the hot springs. "Well, Keiji. Would you like to join us?" she asked.
Keiji looked to Yuuto, who shrugged. Basically telling him he was free to do what he wanted and that the Knight of Rias didn't mind being by himself in the hot springs.

Keiji sighed in joy at the warmth of the water. Luckily, it was big enough that his height didn't make it hard for him to be submerged in it. The steam arising from it made things seem even more blissful. 'I never want to leave.'
"Ara ara, are you enjoying yourself, Keiji?" Akeno purred out, getting close to him and smiling with the same sensual smile.
Keiji just nodded.
"Let me make it even better for you," she told him as the others looked in shock to find Akeno rubbing her breasts on his body. "Well... How do my tits feel? They're bigger than Rias, you know," Akeno added on purpose.
"Akeno! That's unfair!" Rias called out, Asia and Koneko nodding in agreement.
Keiji gripped her breasts in response, watching it bounce as he had one hand on his cock and began rubbing it against her thigh, making her coo and making Koneko and Akeno gasp at the size and strength of it. "The more you know, huh?" Keiji muttered, busy on Akeno as he began using his fingers to tweak her nipples from side to side.
A blush fell upon Akeno's cheeks as she began to brush herself even more against Keiji, fully moving her thighs over his dick and moving it. "Ara, it's getting even harder than before. I can't wait to taste it."
Having enough of being idle. the other three rushed in for their go. "Can't we just relax," Keiji muttered but the girls ignored him as Rias went to rubbing her breasts against the other side which wasn't used by Akeno. Asia grabbed his left hand and began to move it into her pussy, the slit opening up while Koneko rubbed her athletic but petite body against Keiji.
Finding himself with four sexy girls, Keiji just let it out as he flipped his cock out of Akeno's grip and it arose out with the splash of water. The girls muttered praise on it as the King and Queen were first to it, both wrapping it up in their breasts.
"This cock belongs to me!" Rias pointed out, moving it up and down.
Akeno simply smiled but it was competitive. "That's not fair to hog it all to yourself, you know!" she shot back as she helped create a double titfuck.
"But don't leave us out of it!" Asia said.
"Yeah," Koneko muttered.
Keiji's dick twitched in response to the ministrations. From Koneko and Asia, the short duo licking it and mewling. To the professional slurping of the busty babes Rias and Akeno. Like a ticking time bomb, Keiji moaned out as white works began to paint all of them. The volume of it was enough to go around for all of them.
"It's only begun," Koneko mentioned, feeling her pussy ache, seeing the looks of the other girls as well as seeing Keiji still sporting a strong hitter even after letting out a load.
The girls took turn sharpening the blade even further as Rias and Asia rubbed their pussies against it while Koneko and Akeno kissed him. Then they reversed the roles, which ended Koneko and Akeno squirting over the cock before it even entered one of them.
First was Rias. Her body thought she had experienced it all but Keiji was sending her to new heights and making her moan loudly as the others watched in jealousy and awe at the way Rias was getting done. "Keiji! You're doing such a good job!" she cried out.
As Rias felt Keiji shoot inside her, his cock still sprang up as he passionately made out with Akeno and then went inside her in one go. Her toes curled, this feeling of domination was something Akeno found herself enjoying as Keiji roughly and quickly used her pussy to his dick's desire.
'The domination! I-I love it so much! I need it, Keiji!' she cried out, happily smiling as Keiji followed her mind's wishes and treated her to his milk coursing through her body.
Asia yelped as Keiji lifted her small frame up and spread open her pussy again. The feeling was something she had experienced recently. It hadn't truly left her but the sensation spreading into her insides again was enough to make Asia shiver.
"Keiji! It's big and insane!" she cried out, her head falling back and showing the delirious look on her face as Koneko's eyes widened in shock from seeing just how good it must have been.
Keiji gritted his teeth. "I'm gonna treat you again, Asia!" Keiji groaned from hearing Asia's scream as his load entered her once again.
Koneko gulped when she saw it was her turn. 'Why do I feel so hot and embarrassed?' she thought to herself.
She yelped as the draconic Keiji couldn't hear much except fuck her into a pocket pussy, which he did as Koneko's screams of lust only fuelled his desire to fuck her silly. 'It's so tight and welcoming!' Keiji thought.
Koneko's tongue hung out as having her belly bulge from the dick was driving her insane. Her senses commanded her to let Keiji breed her. "B-breed me, senpai!" she cried out.
Keiji sucked on her lips as he heard that and focused his hands to her and continuously pulled her on and off his cock as much as possible. 'I'm gonna surprise her!'
The surprise was a fuck ton of cum that sent Koneko into ecstasy, as she intensely tried rolling her tongue around Keiji and maximise her pleasure. Once done cumming, Keiji's cock stayed in there for a bit before Koneko grew tired.
***
Once again, Keiji was doing one-on-one training with everyone. He had already done some dodging practice with the fallen angels as well as learning how to control your energy and refine it as such.
His training was Koneko was now focusing on hand-to-hand combat. Koneko's fists were strong but they lacked the accurate direction to fully crush Keiji, not that her punches were weak by any measure. It just felt a bit lacking to Keiji.
Learning about more magic with Akeno, Keiji and Asia watched as she showed him different elements. Freezing a cup filled with water. Keiji started with the element most common to dragons: fire. Asia focused more on healing. That said, just like with Koneko, Keiji felt like Akeno wasn't as seductive as she once was. Sure it helped him focus but it was more worrying with the sudden change in tone.
With Yuuto, and with Keiji's request, there was some swordsmanship that Keiji was being taught. Yuuto taught him how to grip the blade, different stances, how to read your opponent. It was definitely fun with Keiji smiling and all.
Since Rias was busy training in her own way, Keiji had some spare time of his own and he went out to talk to both Koneko and Akeno. "I know this is a bit strange calling the both of you out here but I wanna talk."
Akeno kept her smile. "Are you planning on having a threesome with the both of us?" she joked.
Keiji shook his head. "Maybe but I wanted to talk to you two if anything is alright. The way you girls were in training was not like you. And now I can't stop thinking about it. I'm going to need you two to talk or else we're staying here!" Keiji warned them.
Both girls had hesitant looks. They wanted to tell Keiji but they feared the potential backlash they might receive. Keiji sighed. "I don't mean to be rude but you need to be honest, even if you are a devil. I don't need to know everything about you, just how I can held your situations. We're fighting to save Rias, so we have to be at your best."
With that being spoken, Akeno and Koneko both exposed their pasts. Akeno about her fallen heritage and falling out with her father due to the death of her mother. Koneko spoke about her sister being a stray devil and the fear of using her true power.
Keiji smirked. "It's fine. I'll be here for you two. Whatever past you may have had, I don't see any reason why I shouldn't accept you. Koneko, Akeno... don't be afraid... I'll be here for you two. I'm not going anywhere," he pointed out.
Akeno had tears in her eyes while Koneko clenched her fists, trying not to show the water works at all. "I felt like I just got teased," Akeno said to Keiji, making Keiji chuckle. She still had her humour.
Koneko nodded. "But we're glad you'll still love us Keiji!"
The emotion switched from sadness to happiness before quickly transitioning into lust as Koneko was sucking on Keiji's cock while Akeno had her pussy all up in Keiji's face, grinding her body against it and moaning from the tongue.
'Senpai is so big!' Koneko thought, her legs twitching as she felt Akeno start to tease her pussy with her tongue.
Three orgasms and everyone was covered in some fluid of sorts. "Why don't you go first, Koneko?" Akeno said.
Koneko nodded thankfully as she began to let her slit be pierced from the thick cock, moaning as she could feel it have an impact on her body. "So deep in my little pussy!" she cried out, hearing Akeno and Keiji moan as the two of them were kissing.
Akeno began to move and cover Koneko's face in her breasts as she groaned from feeling Keiji's hands massage and squeeze her milk jugs.
For Koneko, having been essentially trapped, she was moaning in a lot of pleasure and found herself getting overwhelmed, leading her to prematurely tighten and orgasm over his cock. The thick bulge responded by shooting deep inside Koneko and giving the petite horny cat a nice cum barrage.
"I think that was too much for her," Akeno joked.
Keiji then grabbed Akeno and put her down, gripping her legs and spreading them apart, he beat his meat into her pussy at a ferocious pace. Sweat dripping down his body as he got Akeno moaning like a bitch in heat. "You like that, slutty senpai?!" Keiji joked with the honorific.
Akeno nodded with her tongue out. "How vicious! It's just what I want! Fuck me silly, Keiji! Make me yours!"
"You're already mine!" Keiji growled as he bit down on her breasts and continued to pound and more blood travelled down his cock, increasing the size enough that Keiji was able to reproduce the belly bulge effect on Akeno, too.
Akeno's pussy squirted wildly but the cum was too much for her as Keiji didn't stop until Akeno was properly exhausted and bred. Her legs twitching as the cum was burning up inside her. "I... I love it..." Akeno got out.
***
Battina, the female bat that served as Rias familiar, could feel her pussy stretching wide as Keiji gripped one tit while the other hand was focused on holding her hip down and pumping into her as she tried to speak.
Previously, she had caught Keiji engaging in an intense breeding session with Ilulu that had gotten her hot and bothered. She yearned for the chance to engage in such passionate activities, with which finally came and boy did she feel like there was going to be a lot of cum.
It was useless to try and speak as a flash of cum made her lose her mind, her body twitching and cum dripping from her snatch.
"Master! It's my turn!" Ilulu cried out, her form transforming to her normal form.
She jumped and shredded her clothes but Keiji just caught the shortstack with ease. He guided her to his cock and socked it into her mouth, not giving her a chance to do anything more but obey the command which she did.
'Master's so big, as usual!' she thought with a happy, lewd smile. Her breasts naturally were pressing against his cock, so she decided she might as well help it and began to do a paizuri with it.
Feeling the encouragement of a paizuri was enough to bring Keiji to a climax, spilling it into Ilulu's mouth, and the copious amounts that fell dripped on her breasts. Something she rubbed, making her boobs bounce. "I'm so happy, Master!"
Ilulu was on her front and her face stuffed into the covers as she drooled from her master fucking her madly from behind. The draconic devil dick was stirring her insides up so well that her moans were audible even while being muffled.
"There's always a girl with him!" Rias huffed, seeing Keiji and his familiar getting down and dirty. Rias shrugged. "I guess it's inevitable," she said, stripping down and leaning her breasts into Keiji's mouth, moaning as she felt his aggressive bite on it.
'Oh, mistress is here,' Battina thought, weakly massaging the cum sloshing out of her pussy and tasting it. 'I can see why mistress thinks highly of him.'
Keiji pulled Rias' nipples as he finished inside the busty dragon. His attention turned to Rias as she was roughly pushed against the bed, hitting Ilulu. But the pain couldn't even be registered ot care as she groaned from the big beater inside her once again. "That's just what I needed!"
Keiji didn't respond except for grabbing both nipples and shoving them in his mouth at once, making Rias drool and moan like a whore as his mouth somehow opened wide enough to have both melons in at once. 'Fuck her tits and her pussy is out of this world!' he joked.
Her mind went blank once Keiji not only shoved his cock somehow deeper into her cervix, but the force of all the cum gushing into her was enough to send her looking drunk on his dick (even though she was already).
"And to finish it off!" Keiji jerked his dick and shot out another load, covering both his girls in his seed.
***
Keiji wiped the sweat off his brow as he had just finished training with Ilulu, fires dying down and some torn clothing. In addition, Keiji had decided to tell Ilulu about Koneko and Akeno's decline two days ago.
"It would be easily solved if both their mothers were with them!" Ilulu happily stated, with Keiji nodding in agreement.
"Sure would be. If only we could resurrect the dead."
Ilulu stopped smiling. "Master... it's technically not impossible," she said, making Keiji stiffen in surprise. "I have a goddess friend that told me there's a Sacred Gear which allows for such a thing."
Keiji stood up, adrenaline pumping through him. "Do you think we could get it? And bring them back to life?!"
Ilulu pointed a finger to her chin in thought. "I'm not too sure. I'll have to find her and ask her. But I think I deserve a reward for this!" she happily said, something Keiji agreed to with a nod.
***
The last six days was hectic but practically followed the same schedule as Keiji would go about training but he never stopped his daily grind of having sex, mainly because the girls seemed to be quite the nymphomaniacs themselves, thirsting over his dick and constantly getting coated in his seed and taking in his cum.
One time he was plunging into Koneko's pussy over and over again until it was filled with cum. But the horny cat whore wanted more, and so her screams reached the whole mansion as her anus got done in and pounded into a mould for Keiji's cock. It was probably the tightest hole Keiji had been in, but one he would gladly do again and again.
Later on in the hot springs, Keiji was also getting serviced by Rias, Asia and Ilulu. The difference in breasts size was laughably but that wasn't important as the male dragon focused his efforts on bringing the girls pleasure and the girls were focused on serving their overlord, doing things such as licking the cum off each other. Their anuses were also involved, but still not as tight as Koneko's.
Keiji was relaxing on his bed when he found himself getting ambushed by not only the three fallen sluts but Akeno as well, technically making there be four fallen angels. Their goal was to extract as much cum as possible, with all the slutty slurping and wildest paizuris as possible. The whole room was a mess as there was probably enough to fill a few baths. Keiji obviously made them clean it with their tongues as he pounded both holes in with cum. Mittelt got close to being the tightest ass he ever fucked, too.
Keiji had also greatly improved in all assets. He had learnt a power called Dragon Shot. And he had a close contact move called Dragon Dig, which enabled him to make the pain more intense on any damaged spot that was from his attack, essentially breaking it down. There was also fire, his most adapt element. Keiji didn't have enough time but he learnt a bit of lightning along the way as well.
As a celebration for going through 10 days of hard training, there was a feast thrown. However, there was a final party that went on as all the girls that had trained with Keiji decided to throw an orgy on a giant King-sized bed. Deciding to go to hell with it, Keiji agreed and soon the place got smelly and sweaty.
Everyone laid there in a mess. Rias began to cling onto Keiji, getting his attention. "I want to do this with you every single day. I never want this to end," Rias begged out, mumbling a bit as she did.
Keiji gave her a toothy grin. "You don't need to worry about it, princess. We're gonna beat the shit out of Riser. Then we can celebrate with some hot, passionate sex!" he promised her, getting Rias to smile as she closed her eyes.
