Kazuki had just returned from the Norse realm, the weight of his victory over Thor and the successful negotiation still settling into his bones.
The moment he stepped back into the Gremory estate, the tension of battle began to melt away, replaced by a deep, bone-weary exhaustion—and a simmering hunger for the women who had been waiting for him.
After a brief debriefing with Rias and the others, he retreated to his private office to sort through the documents and reports that had piled up in his absence.
After the chaos of the Norse realm, Kazuki had a far more pressing need—to lose himself in the warmth of his harem and clear his mind before the political headaches began.
"Master... how do I look? Is there anything strange about my appearance?"
Two figures slipped into the office, and Kazuki's breath caught in his throat. Rias and Akeno stood before him, dressed not in their usual attire but in outfits that left absolutely nothing to the imagination.
Rias, her cheeks flushed with a mix of embarrassment and anticipation, wore a sleek black leotard that clung to every curve of her voluptuous body. The bunny ears perched atop her crimson hair twitched slightly, and the deep plunge of the neckline threatened to spill her massive, creamy breasts at any moment. Her long, toned legs—thick but firm from training—gleamed under the soft light, framed by sheer black stockings.
Beside her, Akeno had chosen a white version of the same ensemble. The contrast of the pure white leotard against her flowing black hair was devastating, and the black pantyhose with a back seam only emphasized the sinful allure of her long, shapely legs. Her usual seductive smile had taken on a coquettish tilt.
"I-It's the first time I've worn something like this..." Rias murmured, fidgeting with the bunny ears, her eyes darting up at Kazuki with a vulnerability that made his heart clench.
Akeno, for all her composure, was also blushing faintly, her violet eyes glimmering with hope and a dash of nerves.
Kazuki swallowed hard. These two goddesses—the heiress of the Gremory clan and her Queen—were so stunning that diamonds would pale beside them. And yet they doubted themselves. He'd have to correct that immediately.
"You're both absolutely perfect. Fucking breathtaking."
Their smiles bloomed like flowers, and the tension in their shoulders melted. Kazuki rose from his chair, crossed the room, and pulled Rias into a deep, possessive kiss. Her lips parted eagerly, inviting him in. Her tongue met his, entwining with a needy, almost worshipful hunger, and when he sucked gently on her tongue, she moaned into his mouth, her body pressing flush against his.
Akeno watched from the side, her own breathing quickening as the scene unfolded.
The kiss went on and on, sloppy and heated, Rias's arms winding around his neck while her hips ground instinctively against his thigh. When Kazuki finally broke away, a shimmering thread of saliva connected their lips. He guided Rias's hand down to the straining bulge in his pants.
"Ahh..." Rias exhaled, her eyes glazing with raw desire. Her slender fingers traced the rigid outline through the fabric, her touch reverent yet trembling. Even when Kazuki released her hand, she kept it there, cupping him through the cloth.
"So big..." she breathed, looking up at him with the adoring gaze of a female utterly conquered by her male. There was no hesitation in her—only a deep, primal need to please.
She sank to her knees with a natural, fluid grace, her face level with his groin. Both hands framed the tent in his trousers, stroking and massaging with a tenderness that bordered on worship.
Her long fingers traced the shape of his cock through the fabric, outlining its girth, and her eyelids drooped with pleasure at the memory of what lay beneath.
"It looks... painful..."
"Then give it some relief."
"Ahh... yes..."
Her hands crawled up to his belt, the buckle yielding to her deft fingers with a soft clink. She freed his erection from the confines of his boxer briefs, and it sprang forth, thick and veined and arrogantly erect. The sight of it—the musky scent—made Rias's head swim.
"Hard... and so big..."
Her delicate fingers wrapped around the shaft, measuring its thickness. She nuzzled the base, rubbing her cheek against the hot, rigid flesh like a cat in heat, then pressed soft, reverent kisses along its entire length. Everywhere her lips touched, she left a smear of lip gloss and adoration.
"Mmm... chu, nnn..."
She circled the glans with the tip of her tongue, licking up the bead of precum that had gathered, her gaze never leaving Kazuki's face. Her eyes were wet, drunk on lust, and the sight of her—the Crimson-Haired Ruin Princess, on her knees, servicing him with such devotion—sent a jolt of raw power through him.
"Good. Now, hands against the wall, ass out," Kazuki ordered, his voice rough.
Rias obeyed instantly, rising and turning her back to him. She bent over, pressing her palms against the wall and sticking out her plump, perfect butt.
The black leotard stretched taut over her curves, and Kazuki reached down, unzipping it slowly, peeling the fabric away from her skin.
'Ughh!! So embarrassing, yet cool...!'
Rias's face burned, but she didn't ask him to stop. The leotard slid down her legs, revealing a black T-back thong that cut between the firm cheeks of her ass.
Kazuki's eyes devoured the sight—the string side-straps digging into the lush swell of her hips, the thin strip of fabric hiding her most intimate place. Rias, trembling with a mixture of shame and excitement, hooked her thumbs into the sides of the thong and pulled it down, baring her wet, glistening pink pussy to his gaze.
She spread her legs slightly, opening herself up for him. The rush of exposure sent a shudder down her spine, the thrill so intense it was almost an orgasm in itself.
Kazuki didn't make her wait. He gripped her hips, positioned his mighty cock at her dripping entrance, and thrust inside in one smooth motion.
"Ahhhhhhhh!!"
Rias's back arched, sparks bursting behind her eyes as his thick length stretched her wide, filling her to the brim. Her inner walls clamped down reflexively, gripping him like a hot, silken vice. Kazuki groaned, feeling every inch of her tight, wet pussy.
His hips met her ass, and he began to move—slow, deep, deliberate strokes that rubbed against every sensitive spot inside her. Rias's moans grew louder, higher, as he pounded into her from behind.
"Ahh, ugh, haaauu."
Each thrust shoved her forward, and she braced herself against the wall, her hips instinctively pushing back to meet him. The slap of flesh against flesh echoed through the room.
"Ahhh, yes! Master's cock... in Rias's tight pussy, I missed this so please, fuck me deeper... pound my womb!"
The words tumbled from her lips, lewd and desperate, and Kazuki's control frayed. He drove into her harder, faster, the wet squelch of her cunt growing obscenely loud.
