Gremory Mansion — Midnight
Moonlight poured through the tall Gothic windows of the Gremory estate, weaving silver veins across polished marble floors. In her lavish room, Rias Gremory moved in restless silence, the hem of her crimson silk nightgown brushing against her thighs with each impatient step. The air held no breeze, yet a storm churned within her.
She stood by her balcony doors, arms folded beneath her chest, as her gaze wandered toward the stars. And yet, it wasn't the celestial heavens that pulled her attention.
It was him.
"Issei…" she murmured, lips barely moving.
Her brow furrowed. This wasn't supposed to happen. She was the next head of House Gremory and was no stranger to admiration, to flirtation, to suitors polished and powerful. But none of them had made her heart lurch the way he did.
Not like this.
She collapsed backward onto her bed, fisting her pillow, voice muffled as she groaned, "This is absurd. I'm a Gremory. I'm not supposed to get flustered by a boy."
But Issei wasn't just a boy. Not anymore.
He was something more. Something radiant. Dangerous. Ancient.
He carried himself like someone shouldering a crown he didn't ask for—but one that fit him too well to deny.
Rias closed her eyes. Her breath slowed. But her heart kept echoing one truth:
She didn't just want his strength.
She wanted him.

Hyoudou Residence — Issei's Room
The stillness of night had fallen over the Hyoudou home, but within his room, Issei sat perched on the edge of his bed, shoulders bare and glistening faintly with the remnants of sweat. A golden glow pulsed faintly beneath his skin—Sunshine, no longer just a borrowed power, but one now claimed and refined.
She didn't knock.
She didn't speak.
She appeared.
Akeno Himejima.
In a deep violet night robe that fluttered with the last remnants of her teleportation circle, she stood with bare legs, confident posture, and eyes that sparkled like lightning about to strike. Her loose ponytail cascaded over one shoulder, framing a gaze filled with playfulness—and something unspoken.
Something electric.
"Well," she said, one eyebrow raised, "I see you don't lock your room."
Issei didn't flinch. He simply blinked at her, golden eyes unwavering. "Didn't know I had to."
She stepped forward, the quiet click of her heels oddly intimate in the silence.
"Rias got to visit," Akeno said with a slight pout, "and I'm feeling… neglected. Surely you wouldn't deny me the same warmth?"
He tilted his head, his voice calm. "You teleported into my room in the middle of the night because of jealousy?"
Akeno smiled, sultry and unapologetic. "I couldn't sleep. Thought I'd visit you."
[Ddraig: She lies with grace. But it's not deception. It's longing dressed in confidence. She's testing if you'll reach for her.]

She stopped just in front of him, her fingers reaching out to touch his bare chest. Light fingertips traced along his collarbone, and her breath grew shallower as she met his eyes.
"You've been training," she said softly. "Your body's so warm. You feel like sunlight… and strength. That's so… hot, Issei."
He didn't move. "You're not just here to flirt, are you?"
She leaned in slightly, her lips brushing the shell of his ear. "Maybe I'm here to surrender. Maybe I want to see if you'll take control… Or are you afraid of a woman like me?"
Her voice dipped, sultry and teasing.
"Will you tame this thunder priestess, or let me consume you, my dear Issei?"

He rose.
Not suddenly. Not aggressively.
But with presence.
A shift in the air. A wave of heat. A stillness that silenced even her heart for a breath.
Akeno stepped back instinctively as he advanced. Her back touched the wall, her breath catching in anticipation—but she didn't retreat. She smiled.
"Are you afraid of what you're asking for?" he asked, his voice low, like thunder in a smoldering storm.
"I'm hoping you'll make me regret it," she whispered.
Then, with fluid control, Issei took her wrist—not in force, but in command—and guided her toward the bed.
She followed, lips parted, her heart beating wild as she sat on his lap, the thin silk of her robe slipping just enough to bare her shoulder. She leaned in, flushed and trembling slightly, but not from fear.
Issei cradled the back of her head, locking his eyes with hers.
"Akeno," he said firmly, "submission isn't weakness. It's trust. You want to give yourself to someone who won't hurt you. Who will see you?"
Her breathing hitched.
"And if I do want to kneel for you?" she whispered, voice raw.
"Then kneel because you choose to. Not because I ask you to."
The words struck her deeper than any flirtation could. And when he pulled her closer and kissed her, slow, claiming, deliberate, she felt herself unraveling.
Her fingers gripped his shoulders. Her breath caught as warmth spread from where he held her, threading down her spine like molten lightning.
Every kiss was a promise.
Every motion, a command she wanted to obey.
She didn't want to be dominated.
She wanted to be held by someone who wouldn't break her, but steady her storm.
When he pulled back, her cheeks were flushed, her lips slightly swollen.
And her heart?
Thundering.
[Ddraig: You've sparked something sacred. She doesn't want to be owned. She wants to belong. And you… are worthy.]
Akeno laid her head against his chest, the steady rise and fall of his breath calming her.
"Do you think this is wrong?" she asked quietly. "Us?"
"No," he replied, brushing a hand down her back. "I think it's exactly what we need."

They stayed like that.
Tangled in moonlight and silence.
No words.
No expectations.
Just two souls—lightning and sunlight—daring to trust.
Lemon starts here
Akeno's eyes widened in shock and awe as she finally released Issei's dragon, his massive package springing free. "Issei, your dick is bigger than any of my toys," she exclaimed, her voice a mix of surprise and anticipation.
Issei's lust had been building all night, from sleeping next to Rias, being marked by Kuroka, and now with Akeno's submission, it reached its peak. "Now kneel, my pet," he commanded, his voice a low, dominant growl.
Akeno's heart pounded in her chest as she obeyed, her body already responding to his commands. "Yes, master," she whispered, looking up at him with adoring eyes. "How would you like me to serve you?"
A wicked smile played on Issei's lips. "I want to suck every inch of my dick, my pet."
Akeno's tongue snaked out, wetting her lips in anticipation. "Yes, master," she replied before taking him into her mouth, her hands wrapping around the base of his shaft. She took in 9 inches, her mouth stretching to accommodate his size, her hand moving in tandem to jack off the rest. She swirled her tongue around his sensitive head, savoring the taste of her new master, her eyes watering slightly with the effort. Slurp! Slurp! Slurp!
Akeno's own arousal was building, her pussy growing wetter by the second, her love juices dripping down her inner thighs. Issei could see the desire in her eyes, could feel her eagerness to please him. "My pet, use your tits," he ordered, his voice hoarse with lust. "I'm going to fuck your tit pussy and your mouth pussy."
Akeno's eyes glazed over with lust, her breasts heaving with each excited breath. She pressed her large, soft mounds together, creating a tight channel for Issei's cock. He began to move his hips, fucking her tits while she sucked on the head of his cock, her tongue swirling and teasing. He could feel her heart beating wildly against his shaft, her entire body trembling with need.
As his pace quickened, Issei grabbed her head, using it as leverage to skull fuck her. Glack! Glack! Glack! The sounds of their coupling filled the room, a symphony of wet, obscene noises that only served to spur them on. Akeno grabbed his legs, her nails digging into his flesh as she took his length down her throat, her eyes watering, her mascara running.
Issei could feel his balls tightening, his orgasm building. He pulled her head back, looking down at her with a dominant smirk. "Swallow it all, my slut," he commanded, his voice a low growl.
Akeno's eyes rolled back in ecstasy as she felt his hot cum shooting down her throat. She swallowed every last drop, her body shuddering with pleasure. She then took the head of his cock into her mouth, sucking gently as she looked up at him with adoring eyes. "Master, fuck me, please," she begged, her voice hoarse from the effort. "I want your big fat dick, master."
Issei's lips curled into a smug smile. "I will, my little slut," he replied, his voice a low purr. "Bend over now!"
Akeno wasted no time, arching her back and raising her ass in the air, presenting herself to him like a willing sacrifice. She began to swing her hips, teasing him, taunting him, spreading her pussy lips to give him a better view of her glistening, eager hole.
Issei, not one to be teased, thrust into her without warning, his hard, thick cock filling her completely. Akeno let out a loud moan, her voice echoing through the room. "Yesss, master! You're so deep!!" she cried out, her body convulsing with pleasure. "Fuck me harder! Slap my ass! Fuck me like a whore, Issei. Mark me as your whore, my master!"
Issei's hand came down hard on her ass, the sound of flesh meeting flesh echoing through the room. He gripped her ponytail, using it as leverage to pound into her, his hips moving like a piston. "You like your master's dick, don't you?" he growled, his voice a low, dangerous rumble.
Akeno could only moan in response, her body a quivering mess of pleasure and need. "Yes, I only want master's dick," she managed to gasp out, her body convulsing around him. "This is so much better than my toys."
Issei could feel her pussy clenching around him, her body tensing as she approached her orgasm. "Cum for me," he commanded, his voice a low growl.
Akeno's body obeyed, her pussy spasming as she let out a loud cry, her juices spraying out of her, soaking the sheets beneath them. But Issei was far from done. He picked her up, her body limp and boneless in his arms, and pressed her against the wall, his cock still hard and ready.
"Who are you to give me orders, my pet?" he asked, a wicked smile playing on his lips as he slapped her large breasts, watching them jiggle and bounce with each impact.
Akeno let out a loud moan, her body responding to his rough treatment. "Please, harder, master!" she begged, her voice a hoarse cry.
Issei obliged, his hips moving like a jackhammer as he pounded into her, his cock swelling inside her. He took one of her nipples into his mouth, sucking and biting, marking her as his. He switched to the other breast, giving it the same treatment, his body trembling with the effort of holding back his own orgasm.
Finally, with a low growl, he let out his load, flooding her womb with his hot seed. Akeno's body convulsed around him, her own orgasm ripping through her, her body milking his cock for all it was worth.
But Issei was still hungry for more. He slapped her ass, the sound echoing through the room, causing her to orgasm again, her body shaking and trembling in his arms. "Ride me," he commanded, his voice a low growl as he sat down on the bed, his cock still hard and ready.
Akeno, her body a quivering mess of pleasure and need, straddled him, her pussy sinking down onto his cock. She began to move, her hips rolling and grinding as she rode him, her large breasts bouncing with each movement. Issei grabbed her hips, his fingers digging into her soft flesh as he helped her move, their bodies slapping together, the sound of their coupling filling the room.
Issei took one of her nipples into his mouth, sucking and biting, his hand coming down hard on her ass, turning it a bright, fiery red. He could feel his own orgasm building, his balls tightening as he drove his cock up into her, their bodies moving in perfect sync.
With a final, low growl, he let out his seed, flooding her womb once again. Akeno's body convulsed around him, her own orgasm ripping through her, her body milking his cock for all it was worth. She collapsed onto his chest, her body boneless and spent, a satisfied smile playing on her lips.
Issei wrapped his arms around her, holding her close as they both came down from their high. He could feel her heart beating against his chest, their bodies moving in sync as they breathed together. He touched her, caressing her into his embrace, his fingers tracing lazy patterns on her soft skin. She sucked on his nipple like a baby, her body content and sated, a look of pure, fanatical devotion in her eyes.
"You will keep my dick in your pussy and ride me as soon as you wake up, am I understood?" Issei asked, his voice a low, dominant growl.
Akeno looked up at him, her eyes filled with love and devotion. "Yes, master," she replied, a soft smile playing on her lips. "I live to serve you, my love."
And with that, they both drifted off to sleep, their bodies entwined, their hearts beating as one, their souls forever bound by the passion and intensity of their lovemaking.
["Well done, Partner. You're not just taming her. You're making her yours."]
When it was over, Akeno lay curled against his chest, her face flushed and her breathing uneven.
"Mmnn," she whispered against his skin, voice dreamy, "I knew you had it in you…"
He stroked her hair. "You still think I'm a drake?"
She giggled. "No, my master. Definitely not, you are a full adult dragon."

As she drifted into sleep against him, he leaned back and closed his eyes. Not just satisfied—but anchored.
His power was growing. His confidence, rising. But more importantly, he was building something deeper.
Back in Gremory Manor, Rias Gremory stared out her window, unaware that she had just lost her lead. Rias had a hard time sleeping that night. At the same time, the black cat Kuroka watched the full show while playing with clit wishing she was getting fucked like that.
