Chapter 18: Parents' Day

"So you could tell it was me?"

Keiji huffed at his rival. "Yeah, and what? Your presence was all too familiar. I feel like I can read your mind just from the way your aura reacts."

The White Dragon Emperor pointed at him, making Keiji wonder if he should respond with his favourite gesture. "That's good, really good. For someone who only recently became aware of his status as the Red Dragon Emperor, you've come far, like stumbling upon such a powerful Familiar; I can't wait for our battle. The name is Vali."

"Fuck off. I'm not bothered with that shit," Keiji replied, looking him dead in the eye, to which Vali could only laugh at.

Durandal came to his throat, with Yuuto holding the Sword of Betrayer to his throat. "Even this is too far, White Dragon Emperor," Xenovia commented.

Despite the perilous situation, the smile never left his face. "Do you really think I'm worried because you are this close? If I wanted to, I could easily escape and take the both of you down. I think the Red Dragon Emperor knows that well enough."

"It seems Azazel can't stop letting his minions run free," Rias said.

Vali shrugged his shoulders, as the Knights relinquished their blades. "Rias Gremory, you have a strong soldier! Keep training him well, because I hate disappointment. See you around."

He was gone the next moment, and Keiji gave him a middle finger as a going away present; Asia still hasn't fixed that habit of his.

In the classroom, Keiji was tapping his pencil as his brain couldn't focus. The reason? 'Xenovia's been giving me the fuck-me-silly eyes for so long. Has she even started the work?!'

Thankfully, the period was pretty quick, so they got up and sped out of there like they were late for the train. Xenovia trailing Keiji towards the Kendo club location; the Red Dragon Emperor resigned himself to what was going to happen.

Walking out in the beautiful sun was a beautiful third year. Her figure was similar to Xenovia but a bit more. She had long, brown hair arranged in multiple drill-like curls.

'It feels good to be a monster tamer,' Kiyome Abe thought as she pondered on what her talent had allowed her to do. 'So many mystical beasts out there for me to tame! And I'll do it! I'm sure it would be enough for my family to see how strong I can become!'

Her inner monologue was interrupted by a strange, stuffing of noises all into one. While it felt like she could decipher it given time, Kiyome was impatient and carefully followed the noise, leading her to a small hole in the wall.

Twice now the hole in the kendo club was being used as now Kiyome was the woman to watch Keiji in an intense sex session with the kendo club girls, Aika, but with the addition of Xenovia, who obviously wanted to practice her baby-making skills.

Fumes of lust made Kiyome's face upturn into bliss as her hands travelled underneath her clothes, one latching onto her chest while multiple fingers swam down into her pussy as she tried to quell the sudden flaming fuck urge that spawned. 'J-just from watching them?! I can't be that desperate!'

The next few moments were a blur for Kiyome as she blinked with lidded-eyes to find herself in the shower room of the kendo girls.

Before she could even have a moment to herself, like a crowd of die-hard fans, the other kendo club girls welcomed her with hearts in their eyes. Not that she could even think right when the girls began to undress her and held her out to Keiji, with her legs spread out.

"Keiji! Breed Kiyome-senpai!"

Keiji turned his head, with Xenovia's body still pressed up against the wall and a hot mess as cum dripped down from her pussy and down the walls; the water carrying it away down into the drains.

"Hmm? Sure, I guess. If you don't mind."

The beast tamer looked in confusion but she had plenty of time to be vocal about rejecting the rod, which she didn't. However, she got vocal real quick the moment it went into her small clit.

A cum-filled Xenovia watched as Keiji massaged his hands over Kiyome, thoroughly teasing and pleasing her at the same time as Kiyome gasped when Keiji's finger flicked her sensitive nub. 'I should remind Keiji to do that to me next time.'

"Keiji is going really hard into her!" Aika remarked with a perverse smile as she watched in awe at the way Kiyome's flesh jiggled every time it made contact with the ramming that was Keiji's dragon dick.

Keiji leaned down as he began to meet Kiyome's quivering lips into a kiss, the third-year tennis player a mess as she felt herself becoming fully suffocated by the pheromones letting out. Her body wasn't used to this level of pleasure, and she thrashed wildly against him as her hands wrapped around him and held him as if she was trying to snuff his breath.

'She's really sensitive, I think. She's squeezing a bit too hard!'

Trying to relax, Keiji resorted to threading his fingers into her had. That ended up having the opposite reaction as Kiyome arched her back in joy, toes curling and her legs wrapping near his pelvis as Kiyome helped with impaling herself on the thick individual. "I-I'm so close! Keep it all inside me, and I'll give you my future!"

Keiji just hoped she wasn't just saying it in the heat of the moment, but it was still a hot thought that provoked his penis enough for it to start firing off inside her, melting her insides with his white army as they swam all around her womb and settled nicely there. Enough warmth to start a fire.

Kiyome was placed gently against the wall as Keiji slowly eased her down, removing his cock slowly like a doctor, cum slipping out, with a rope between her pussy and the slit of his dick. "Okay, I think that's enough," Keiji said.

Except Xenovia was already up and running again. "More baby-making?" she asked.

"Fine."

After that mess, Keiji was back in the clubroom. "So... she's part of some beast tamer family?" Keiji asked with a grunt.

Rias nodded, her cheeks clapping down as she rode him again and again, never getting tired from the feeling and joy it brought her. "That's right! But... Keiji... you keep on adding girls! It's going to decrease our time together!" Rias complained.

"Then I'll make the most of it now," Keiji said, flipping her over and landing on top of her as Rias began to breakdown into moans from the rough mating press position.

***

Parents day had arrived for everyone. Sirzechs had managed to come and dote on his little sister while the parents recorded the classroom activities. Grayfia and Venelana were also present, for very obvious reasons.

"Rias, you okay?" Keiji asked, seeing the stressed out look on his King's face.

Rias nodded. "My brother is just so doting. Sure, it's nice to have family around, but they are just so overbearing it's uncomfortable."

"Hey! There's a sexy cosplayer in the auditorium!" someone shouted, with a whole army of boys rushing towards the location.

Not really having anything to do, Keiji followed the crowd as to who this cosplayer could be. "I'm just curious really," Keiji told Rias, already knowing how possessive she could be.

"That makes the two of us."

In the auditorium, the cosplayer was in sight. Keiji didn't need to be up close to see that she was small in stature. Her attire was magical girl clothing, with her holding a magic wand.

"Everyone, move out! This isn't a game!" Genshirou said, somehow getting the people to stop gazing at the girl. "And you, this isn't a place where you can cosplay! Are you someone's parent?" he asked.

"What, that's unfair?! What do you mean I can't cosplay?!"

Keiji had to feel bad for Genshirou. 'Being in the student council must suck. Still, who the hell is she?'

"You haven't been introduced to her yet, Keiji. But she's the Leviathan Satan. Serafall Leviathan," Rias explained.

The doors opened up as Sona came in. "Genshirou, what's with the mess?" Before she got her answer, she looked at who was up on stage and gasped. "Oh no."

"So-tan!" the Satan screamed, flying forward and embracing her sister.

"Sister... why are you here?" Sona asked, dreading each moment.

Serafall only hugged tighter. "Why wouldn't I be here, my adorable little sister?! You didn't even tell me about it. I had to find out from Sirzechs-chan! I almost went to go fight Gabriel in heaven because of it!" The last part was said a bit more seriously, but still in a childish tone.

"If you did that, this country would be destroyed several times over."

Keiji couldn't help but look in shock. "Seriously... She's actually that strong. This devil cosplayer could wipe the floor with me. I'm in shock."

Whether it was perfect timing or not, Serafall noticed Keiji and was already in front of him, her eyes narrowing at him, while the latter looked at her with a raised eyebrow. Even being up close, Keiji still couldn't see how the older sister of Sona could be a high ranking leader of the devils and a crazy cosplayer.

The inspection didn't end just there, with Serafall looking him up and down. Similar to many women before her, she inhaled his scent. The pheromones worked but her strength allowed her to hold back a possible blush and the moan she wanted to let out.

"So... is she done?" Keiji asked Rias, who just shrugged, while Sona was looking like she wanted to leave.

A smile came upon Serafall's face. "At last! I've wanted to personally meet the evil dragon who stole my So-tan's innocence! I've got a bone to pick with you! You took away my responsibility! You're almost as bad as Gabriel!" she stated, very childishly, while stamping her legs.

The rambling was too much for her. "I can't take this, sister!" Sona called out, running out for the door, with her older sister exiting rambling mode and going back into possessive sister mode.

***

After a very eventful day, it was time to go home. Grayfia and Venelana decided to have another sleepover at the Hiryu mansion as they would be busy in the Underworld, so some more fun time was there to scratch their itch. 

In addition to that, Serafall decided to join in as well, still unaware of the reason why the maid and the MILF were sleeping over. Keiji couldn't help but groan but could he really just tell a Satan that she wasn't invited.

"So-tan.. keep kissing me right there," Serafall mumbled with a silly smile on her face as she turned in the bed, her loose magical pyjamas undone and showing skin.

As she kept on murmuring, her eyes fluttered open and she took a moment to adjust as she was now fully awake. Her devils senses picking up on all the loud noises.

Letting her senses guide her, she came to the massive bedroom of Keiji. Venelana and Grayfia were by his side, except they were drunk and dripping cum. Her brain barely processed that as she focused on Sona's frame rocking against his cock, an explosion of cum and a loud screech from her usually strict little sister. This is what had Serafall's full attention, not even realizing Rias, Ravel, Akeno, Tsubaki & Yubelluna's fucked-silly bodies.

Right as Keiji pulled out of her little sister, Serafall didn't even hesitate as she stripped out of her pyjamas lazily and was drinking the dragon drip that fell out of Sona, mewling in joy at being able to do something so lewd.

'Ah, I've always wanted to drink from a fancy cup like this! Just to find out that someone has filled it with such an addictive dragon dick!' she monologued lewdly, getting off at hearing her little sister moan so dirty.

Preoccupied with eating out Sona, Serafall was unaware of the boss behind her. Keiji looked her up and down, her ass bouncing side to side and up and down, making Keiji question. 'Hell! Why not?!'

Serafall gave a brief pause to cunt consuming as she felt Keiji's legs against hers and a dick up her pussy. "Give me more of that!" she begged, but it came out distorted as Serafall easily got horny and distracted from Sona's slit.

Keiji rocked his hips hard straight from the start, not pulling anything bag. Even if she was a virgin, the fact Serafall was stronger than him was enough to persuade him to go with pounding hard and use super speed. "I'm going to take that as a good sign to continue."

Serafall managed to give a thumbs up in response, then she went back to gripping her sister's thighs and viciously devouring her vagina like she was hiding something in there. Apart from another orgasm.

Being horny enough for her sister allowed for Keiji to make his way further through her penis-loving passage not that hard, which was definitely a surprise, but a welcome one to be sure as Keiji reached out and gripped her nipples from below; her small stature helped him with that.

'Keiji is so good! This must be what Sona feels! How rude of her to leave her big sister out of this?!' she managed to complain coherently, before losing herself to the sex as her fingers began to tease Sona's anus.

Sona's whole body was being dominated by her older sister, enough to make her lose movement control. However, the older sister was starting to be put in the same predicament as Keiji was becoming a beast in battle, clenching on her breasts like his fingers were duct tape, and hooking his dick deep in and pulling her like she was fish in the water.

Eventually, even Keiji was becoming too much for Serafall to handle, as she tried to get back to eating her sister's pussy, only to have Keiji slam her in from behind and make her screech, squirting all over his cock, and already feeling another orgasm coming in.

From above, Sona gave a smirk as she saw her big sister finally being dominated. The sight was so hot, that, on her own, Sona decided to embark down and give her a searing sister kiss back, instantly making the older sister's body overreact and aggressively climax over on Keiji's cock, not to mention the continuing tightness.

'Yeah, no holding back!' Keiji thought, watching the two of them in action as Keiji jumped Serafall and sandwiched her into her taller, little sister as he flooded her walls. "Try not to lose any, Leviathan!" Keiji teased as Serafall began to lose herself in the feeling.

When enough time had passed, Serafall was given a chance to breath as she came out with the same fucked-stupid face that her little sister once had. "I want to make out with So-tan while Kei-kun pumps me full of dragon milk forever!" It would have been cute had it not been for how lewd and down bad it was.

"Rias!" Venelana called out to her daughter, trying her utmost to focus while riding Keiji down and feeling him pump up into her like a ravenous beast. "Sirzechs said... that it's time to unseal your other bishop!" Venelana gasped as she managed to get it out. "Fucking horny dragon!" Venelana swore as she placed her arms against him and smashed down on him while biting her lips in lust.

Rias would have had a more surprised face had she not been blushing from Keiji eating her tits like a starving baby. 'I would ask, but no time! Just more time of fucking Keiji!'
