Accord

"Oh, my...oh me, oh my..." remarked Akeno, wide-eyed as she entered Rias's room and found her exhaling throaty from beneath Vahn, the two still going at it despite the sun rising in the sky outside.

"Is it...already that time...?" panted Rias, clinging to Vahn with her arms and legs, her brain tingling in a way that made it difficult to and her eyes unable to focus as pleasure beyond her previous ability to imagine spread through her in pervasive, all-encompassing waves.

Hearing Rias speak, Vahn ceased his ceaseless ministrations, his face red and eyes filled with passion as he met his beloved girlfriend's watery gaze and asked, "Did you say something...?"

"Good morning, Vahn~" hummed Akeno, causing him to startle slightly as he hadn't noticed her presence at all.

"Oh...good morning, Akeno..." responded Vahn, realization dawning on him as the words left his lips, a look of confusion marring his face as he asked, "Wait, it's already morning?"

"And you two are in desperate need of a bath," appended Akeno, nodding as she approached the bed with the usual warm towels and tea. Vahn was clearly reluctant to do so, but since he knew he and Rias couldn't just skip school to continue having sex, he got off of her and sat up, leaving her to pant in place with her legs splayed like less and greater than signs.

"Oh, my..." muttered Akeno, her eyes widening to their limits when she saw the condition Rias was in, their gazes meeting as the latter's chest heaved and a weary but gratified grin adorned her face.

Recovering from her shock, Akeno narrowed her eyes, sporting a deeply affectionate and slightly sadistic grin as she sincerely remarked, "You look especially beautiful right now, Rias..."

"She really does..." affirmed Vahn, staring at Rias with an intense gaze that made it seem like he might resume his ministrations at any moment.

Exhaling a faint chuckle, Rias closed her eyes and responded, "Thank you both..." before focusing on regulating her breathing. Akeno helped her by laying the moist towel over her face, which may not have made aspirating easier, but it felt pleasant.

"Speaking of appearances..." said Akeno, looking Vahn up and down with a scrutinizing but appreciative gaze as she remarked, "It could just be my mind playing tricks on me due to envy, but you appear to have grown a bit taller and become more muscular, Vahn..."

"Really...?" asked Vahn, looking down and inspecting himself, finding that he did, in fact, appear more muscular. He knew that his appearance was influenced by his image of himself and his desires, but he didn't expect to suddenly develop a six-pack, muscular arms, and a notably broader chest and shoulders. And those weren't the only things that had grown...

Rising from the bed, Vahn confirmed both his and Akeno's suspicions as his height, which was previously 175cm, was now closer to 180. It would definitely appear conspicuous to those who knew him, but Vahn couldn't help feeling happy as he teased, "You got shorter..." despite Akeno's 168-centimeter height being well above the national average.

"Oh, believe me, Vahn...it is most assuredly you who has gotten much bigger..." contended Akeno, crossing her arms and narrowing her eyes as she stared directly at Vahn's battle-ready hyper weapon. She had seen it at the ready several times before, but it appeared especially imposing as it glistened with a mix of his and Rias's fluids.

As she had been listening to Akeno's and Vahn's exchange, Rias promptly removed the towel from her face, her body feeling like lead as she forced herself to a seated position, crossed her arms under her breasts, and her right leg over her left as she sat on the bed's edge, exuding a poised aura befitting her status as she said, "Let's establish some ground rules."

With Vahn's and Akeno's gazes fixed on her, Rias, her face tinted almost like a drunkard, stated, "First off...I am greatly impressed by your stamina and deeply appreciate your enthusiasm, Vahn. That said, my mind or body will invariably break if we repeat this daily. As such, the next phase in your groom training will be learning restraint..."

"Sorry..." muttered Vahn, visibly shrinking a few centimeters as he lowered his gaze in shame.

"Do not apologize," said Rias, adopting a broad smile as she assured, "You were incredible, Vahn. The problem is that you were too incredible. I need time to acclimate and train myself to your level."

Seeing Vahn regain his vigor and smile, Rias nodded approvingly before shifting her attention to Akeno, stating, "Until then, Akeno, you will fill the role of my second. Serve Vahn well when I am unable."

"I am not exaggerating when I say it will bring me great satisfaction to be of assistance~" hummed Akeno, pulling up the front of her skirt slightly to perform a curtsy.

"I don't know..." said Vahn, drawing the two girls' attention as he rubbed the back of his head and pointed out, "I was really upset when I learned what happened with Issei...it just doesn't feel right for me to do what I did last night with other girls..."

"Even if I'm the one asking and permitting you to do so...?" asked Rias, feeling a profound sense of gratification but also a tinge of guilt. Things were going smoothly before what happened with Issei, but now it seemed that Akeno and Koneko would need to find separate partners. That wasn't necessarily a bad thing, but since the presence of powerful males in close proximity to one another tended to result in unhealthy competitions and rivalries, particularly among young Devils, she would prefer to keep things simple.

Hanging his head and exhaling a faint sigh from his nose, Vahn had mixed feelings but raised his gaze to meet Rias's, answering, "If you're okay with it...we can at least give it a try and see how things go. But if you ever, and I mean ever, feel sad or regretful because of something I did with another girl, you have to tell me. I don't want to hurt you, Rias..."

"And that is why I adore you..." responded Rias, forcing herself to her feet and hugging Vahn's face to her breasts, cradling his head and resting her cheek atop his crown. When he reciprocated her embrace, a certain part of his body naturally came to nestle between her thighs, its heat radiating through her, but she didn't mind in the slightest. Rather, after learning how comprehensive Vahn was in his lovemaking, she was very optimistic about their future...

"What the Hell? Did you swallow some kind of magical steroids? You look the ace of a boys' swim team or karate club," remarked Issei, wide-eyed as he arrived at the classroom and saw Vahn's changed appearance. Rias had tweaked the barrier over the Academy so that ordinary students and faculty members wouldn't notice, but he most certainly did.

Shaking his head, Vahn attempted to make Issei realize they shouldn't be talking about such things with people present to overhear them by flatly asserting, "I don't know what you're talking about. This is how I've always looked..."

"Uh...okay...?" responded Issei, his expression one of confusion as he took his seat and pulled out his textbooks and notebook. Vahn frowned slightly when he opened the latter to the pages depicting the recreation of Rias's breasts, but his valuation of Issei once again improved as the newly made Devil promptly tore out the pages and crumpled them up, stating, "Oops, I forgot those were in there. My bad."

"It's fine..." assured Vahn, quickly supplanting, "Well, it's not fine, but you know what I mean..."

"Yeah, I get you," said Issei, beaming until Aika came over, intruding upon their exchange to ask, "What's going on here? Issei, you're not corrupting the class's Dark Prince with your evil ways, are you?"

"No, but you should have heard him yesterday," responded Issei, causing the eyes of several girls in their surroundings to sparkle as he revealed, "I asked Vahn if he was more into breasts or butts, and he surprised me with some really poetic words about a girl's eyes and reflections and stuff. You would have wet yourself in the biblical sense."

"Hooooo? And what do you think of my eyes...?" asked Aika, directing the question at Vahn with a narrow-eyed, distinctly predatory smile. What she didn't expect was for him to look directly at her, causing her to feel a little nervous as he seemed to peer into her innermost depths.

Before Vahn could offer his sincere opinion, Aika turned her head, looking uncharacteristically vulnerable as she said, "Scratch that...I don't want to know," before confusing everyone who knew her by turning and departing for her desk with notably reddened cheeks.

"Holy shit, dude...did you seriously just get Kiryuu Aika, of all people, to behave like a maiden...?" asked Issei, staring at Vahn with a mix of horror, disbelief, and admiration. Aika was widely regarded as the most perverted and knowledgeable girl in the entire Academy, so much so that she often humbled him and the other members of the Perverted Trio. Seeing her get flustered by simply holding Vahn's gaze for a few seconds was a scene he couldn't have imagined without seeing it...

Correlating the word maiden with the word virgin, Vahn tilted his head to the side and questioned, "What do you mean? Why wouldn't she behave like a maiden?"

"I mean...it's Kiryuu Aika..." answered Issei, unsure how to explain what he meant in detail without invoking the bespectacled girl's wrath. What he, and nearly every other person in the Academy, didn't know was that Aika, despite her lascivious behavior, was still a virgin. She was very well-informed, yes, but all her knowledge was theoretical and mostly centered around her in-depth understanding of herself. She had never experienced a boy gazing deeply and intently into her eyes as Vahn had, so for the rest of the day, she appeared gloomy and standoffish but was actually just too embarrassed to meet anyone else's gaze...

"Wow...this place totally reminds me of those cutesy-yet-terrifying dungeon-mapping games that were super popular when I was a kid..." remarked Issei, a broad smile adorning his face as he looked forward to fighting monsters, becoming stronger, and collecting loot for real rather than in a video game.

"Just keep in mind that you're currently only around two to three times stronger than the average human," said Rias, standing, as usual, with her arms crossed as she explained, "Our priority for today is helping you to awaken the Sacred Gear slumbering within you. That is the penultimate expression of your connatal talent and will be the key to you increasing your strength quickly."

"Right...!" responded Issei, holding up and pumping his left fist. He had always believed a hidden power slumbered in his left hand, despite most others making fun of him for it, so when he learned from Rias that he was correct, he nearly cried tears of joy.

"Come out, my Excalibur...!" exclaimed Issei, thrusting out his left hand at a monster that resembled a butterfly with large purple wings and the face of a very ugly infant.

With nothing happening even after several seconds, Issei swung his arms around before striking a dramatic pose with his right arm crossed over his body and his left hand covering his face, his cheeks gradually reddening as he shouted, "Transform, Psycho Crimson...!"

Looking up at Vahn, who was staring at Issei with an expression of open-mouthed disbelief, Koneko raised her right fist and asked, "Should I knock some sense into him...?"

"Be nice, Koneko," chided Rias, doing her best not to laugh aloud at Issei's antics as she reassured him, "And don't give up trying, Issei-kun. If you're embarrassed by your power, how can you expect it to respond to you? Let all your passion and desire flow out, and embrace the purpose within your heart. The power sleeping within you will only respond once you embrace that desire and form it into an ambition."

"An ambition..." repeated Issei, staring down at his left hand and balling it into a fist. Throughout his seventeen years of existence, a singular desire had driven him more than any other, so after forming his resolve, he held his fist up to his head, closing his eyes as he muttered, "There is only one thing I desire..." before opening them to glare at the butterfly monster, his mind's eye allowing him to picture it as a ginormous pair of breasts...
