Devilish Nature

"Alright, then, I'll see you this afternoon," muttered Rias, holding Vahn's hands and planting a kiss on his cheek before separating from him to join her mother, sporting a playful, narrow-eyed smile as she raised her right hand, wiggled her fingers, and hummed, "And if circumstances permit, I'll hope to see you this evening~" in a sultry tone.

"That's quite enough out of you..." groaned Rias, her face flushed as she pushed her mother along, prompting her to exhale a light-hearted laugh as Akeno, the last to depart, gave Vahn a droopy-eyed bow before turning to catch up with the mother-daughter pair and their escort.

Waving his hand at the departing group, Vahn couldn't help thinking back to what Issei had said the previous evening, specifically that being a Devil was the best. He had some internal scruples, but witnessing how Rias and Venelana played off each other as he made love to and allowed himself to be attended by them was liberating and, put simply, fun...

"Shall we be on our way as well...?" questioned Grayfia, standing a short distance behind Vahn with a cool smile and her hands folded neatly atop her lap. In response, Vahn turned to face her, his gaze meeting the silver-haired Maid's equally silver eyes as a slight tension permeated the space between them. Her and Venelana's situations were distinctly different, as she was Sirzechs's only partner and vice-versa, but after crossing the line with his fiancee's mother, Vahn couldn't help reflecting on the many times she had implicitly or overtly tried to tempt or seduce him...

Noticing the indecision and hunger in Vahn's gaze, Grayfia's silver eyes narrowed, her smile gaining a hint of sensuality as she produced a silver pocket watch, checked the time, and pointed out, "If we teleport instead of walking, we should have twenty to thirty minutes to spare...what would you like to do?"

Closing his eyes, inhaling a deep breath through his nose, and exhaling through his mouth, Vahn calmly responded, "I don't want to complicate things between you and your husband..."

Opening his eyes and meeting Grayfia's gaze, Vahn added, "And I'm a bit of a hypocrite...because, even though Venelana-san has been married for a long time, I would like to keep her to myself..."

"Suggesting that you would like to monopolize me as well..." concluded Grayfia, a thoughtful expression adorning her face as she closed her eyes in poised reflection.

"Sorry...I know I'm being an idiot..." sighed Vahn, shaking his head in self-exasperation. He understood how absurd it was for him to want Venelana and Grayfia to be faithful to or prioritize him over their husbands, but that was how he felt. It wasn't rational, but that was the nature of emotion and desire...

"Vahn-sama is not an idiot..." asserted Grayfia, her expression and tone firm, leaving no room for argument, before she adopted a faint smile and maintained, "You are simply young and coming to terms with your wants, needs, and desires. Once you have had the time and opportunity to grow, both as a person and the God you have the capacity to become, you will be able to look back on moments like this and laugh heartily."

"And how long will that take...?" asked Vahn, his expression relaxing but sporting a self-deprecating smile.

"I'm not sure..." conceded Grayfia, leaving Vahn confused as she turned her back to him. Then, hiking up the back of her long skirt to expose her tantalizingly fair and round bottom, parted by her black, string-like, side-tie thong, she peered back at him over her right shoulder and stated, "But I can attend you until you find the answer for yourself..."

"What about your husband...?" asked Vahn, swallowing nervously as he allowed his gaze to fall to Grayfia's ever-tempting bottom. He had seen it hundreds of times and even massaged it, but it was never as tempting as it was at that moment.

"Sirzechs-sama is my King and the leader of the Underworld before he is my husband..." responded Grayfia, elucidating, "His highest priority is the peace, stability, and prosperity of his people. Vahn-sama might not be the type to leverage his status and power to such ends, but if it would ensure your support for the duration of our interchange, he would have me serve you indefinitely..."

"I would never predicate my support on such an arrangement..." muttered Vahn, his gaze still firmly fixed on Grayfia's bottom.

"Of course not..." hummed Grayfia, leaning forward slightly and arching her back, giving Vahn a better view as she added, "But you should know by now that much of Devil society hinges on contracts and exchanges of equivalence...it makes those in power uncomfortable when someone who uses their power selflessly appears as it causes the people to reconsider their allegiances. It's only a matter of time before Vahn-sama's influence expands tremendously, so you can view this as a measure of keeping the people's expectations tempered..."

"And what about your son? What about Millicas...?" asked Vahn, finding himself drawn close enough to stroke Grayfia's exposed bottom, his left hand and palm tentatively caressing her left butt cheek.

"Millicas-sama has understood since a young age that my duties and responsibilities come before him..." responded Grayfia, closing her eyes and focusing on the sensation of Vahn's caress as she asserted, "He also understands his own as the son of Sirzechs-sama and the second-in-line of the Duke Gremory title. He has even started vetting candidates for his Peerage and requests frequent updates on the status of his future domain and people..."

"I think you should spend more time with him..." muttered Vahn, piquing Grayfia's interest and compelling her to make a mental note as he softly but firmly asserted, "There is nothing more important than a mother's love and acceptance..."

"If Vahn-sama becomes my Master, I will surely have more time to spend with him. You could even command it..." contended Grayfia, adjusting her position so that her butt and pussy were nestled against Vahn's prominent bulge. Then, staring back at him with narrowed eyes and an alluring smile, she added, "Just as you could command me to become your personal-use pussy...my sole appeal is that you never flaunt the privilege, particularly in front of my husband..."

Inhaling deeply and exhaling from his nose, Vahn commented, "You make me want to ravish and stay the hell away from you at the same time..."

"Both of which are viable options..." noted Grayfia, narrowing her eyes as she faced forward, closed them, and hummed, "Though, if I have a say in the matter, I would prefer if you chose the former..." while leaning into him and grinding against his bulge.

'I'm definitely becoming more Devil than human...' thought Vahn, causing the smile on Grayfia's face to become more prominent as he slid aside her panties to expose her cleanly shaven, eagerly-awaiting pussy. When he saw how wet she was, it was as though a switch had been flipped in his head, his face and body feeling warmer and his brain tinglingly as he said, "Let's move someplace private..."

"Given our limited time, would it not be best to relocate to the Corridor...?" asked Grayfia, causing a big bang-like explosion of realization in Vahn's brain, prompting him to immediately transfer them to the Checkpoint with the hot springs and reconstructed ryokan.

"And now we have 129 minutes..." hummed Grayfia, staring back at Vahn, curious to see what he would do next. It was somewhat embarrassing to admit, but after seeing how thorough he was with other women, she was looking forward to being on the receiving end of his passion.

"Just so we're on the same page...if we do this, you won't be having sex with anyone else as long as you're in my service..." affirmed Vahn, having already discarded his clothes, his left hand on Grayfia's butt and his right guiding his glans to her pussy, probing her warm and lubricated folds with his glans. It took considerable restraint not to thrust his hips forward, but Grayfia wasn't nearly as hesitant, her silver eyes narrowing into a sensual, smoldering gaze as she held his and gradually shifted her weight against him, his glans slowly prying apart her hot, tight, and incredibly stimulating folds until she had swallowed him completely. Only then did she respond, "If that is what Goshujin-sama has decided...my pussy is yours and yours alone for as long as it pleases you..."

Though his teeth briefly clattered due to the intense stimulation, Vahn, albeit with a flushed face, quickly regained his composure and affirmed, "Then consider it an order..." before grabbing Grayfia's waist, guiding her forward, the stimulation against his glans sending goosebumps across his body before he slowly thrust his hips forward, producing a satisfying and wet-sounding smack.

"As Goshujin-sama wills..." responded Grayfia, facing forward and closing her eyes to focus on the sensation of Vahn's cock spreading her near her limits. She didn't know if it was because it was her first time with another man or because they had been building up to it for months, but each time he thrust into her, it caused her abdominal muscles to contract and sent a wave of pleasure through her abdomen. And though it wasn't that notable at first, she felt like his pre-cum functioned similarly to an aphrodisiac, her insides becoming itchy and hot in response to his incomparably potent life force...

Having learned from Venelana that slow and methodical lovemaking was the best way to leave a lasting impression on a woman's heart, Vahn took his time, focusing on each thrust and the way Grayfia reacted to his glans scraping each of her pulsating, periodically spasming folds. He felt like he would cum at any moment, especially when she tensed in response to him pulling out, but since he had been looking forward to their union for longer than he would admit, Vahn intended to do things properly.

Swallowing hard, Vahn prompted Grayfia to shift her focus to his words as he expressed, "I want to make you feel amazing...so tell me how you want it..."

Sporting a gratified smile that Vahn could make out thanks to his domain, Grayfia unhesitantly revealed, "The thing that gives me the greatest sense of satisfaction and joy is serving my Master...if Goshujin-sama permits it, I will ensure we both feel amazing..."

"Alright, then..." responded Vahn, slowly extricating himself from Grayfia's insides before producing a bed from his Inventory and jumping backward onto it. Then, as Grayfia fixed her posture and turned to face him, he held her gaze, his expression and tone firm, full of passion as he said, "I order you to make us both feel amazing..."

Though it was slight, Vahn noticed a change in Grayfia's expression, her eyes lighting up, her hair billowing, and her Demonic Aura becoming more prominent before she offered him a steep bow and hummed, "It would be my pleasure..."

Raising her head, Grayfia discarded her Maid outfit but, as usual, kept her accessories, stockings, and garter belt. One notable change was that she was missing her exceedingly skimpy panties, but that was to be expected, considering the circumstances.

Climbing onto the bed and Vahn himself, Grayfia resisted her initial urge to give him a blowjob as his order was to make them both feel amazing. With that in mind, she positioned himself on her knees above his cock, holding it against her pussy with her left hand and gently caressing its tip with her right palm as she held his gaze and explained, "I will insert it...from there, the best way to ensure we both feel amazing is if Goshujin-sama matches my movements with his forceful thrusts. Once you have graced my womb and insides with your exceptional seed, we will slow things down, making out as you gently gouge my insides and force my pussy to take the shape of your cock..."

"Proceed..." responded Vahn, swallowing hard before fixing his gaze on his cock and Grayfia's pussy as she leaned back, guided it to her visibly dripping entrance, and accepted him back into her tight and increasingly vacuous depths. From there, things proceeded as she had said, starting with her leaning forward and guiding his hands to her breasts before she began raising and lowering her hips, prompting him to match her pace and thrust into her each time she relaxed her thighs and tensed the muscles in her abdomen to make it impossible for him to penetrate her without giving it his all...
