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?"
[System Alert:

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
She was shocked when she saw how big his package was as she finally released his dragon. Issei, your dick is bigger than any of my toys Akeno exclaimed.
His lust reached its peak from sleeping in the same bed with Rias, being marked by Kuroka, and now Akeno's subduction was too much. Now kneel, my pet. Yes, master, how would you like me to serve you? I want to suck every inch of my dick my pet.
Yes, master Akeno replied before taking in 9 inches while using her hand to jack off the rest. She swirled her tongue around, trying to savor her new master taste. Slurp! Slurp! Slurp!
Akeno pussy was getting wet dripping love juices. My pet use your tits I'm going use your tit pussy and mouth pussy. He could see hearts in her eyes as she sucked his dick like a slut in heat his slut. As he got close he grabbed her head to skull fuck her. Only sounds could be heard where Glalck Gwak Slurp! She grabbed his legs as he fucked her mouth. He finally felt his balls tighten as he got closer and his balls hit her chin. Then he finally let out his cum down her throat saying swallow it all my slut. After she showed that swallowed it all and kiss the tip of his dick. Then screamed master fuck me, please I want your big fat dick master.
I will, my little sult, bend over now! Without hesitation, she arches her back and raises her ass in the air. As she began to swing her ass back in four while spreading her pussy. Issei, without warning thrusting his hard thick dick into her pussy like a piston. She long broke her hymen using her toys. She moans, yesss, master you so deep!!! Fuck me harder slap my ass fuck me like a whore Issei. Mark me as your whore my master Issei. He laid a hard slap to her ass making it red while gripping her ponytail. You like your master dick, don't you? Yes, I only want master dick. This is so much better than my toys. Master, I'm bout to cum. Then cum for me he said in a low growl as she sprayed her pussy juices all over the sheets. My pet we're not done yet I haven't cum yet.
He picks her up and fucked her hard against the wall. She screams please harder master!
Who are you to give me orders, my pet? He slapped her large breasts, causing her to get even wetter than she was already. He got to watch her j-cup breast jiggle then he took one in his mouth and then switched to the other. He finally let out his load, flooding her womb.
He slapped her ass harder causing her to orgasm. My slut ride me Issei said in a low growl. Yes, master. As she proceeded to ride him, her breast bouncing and the sound of slapping as pussy juices covered his waist. He slapped her ass with his right hand turning it red as an apple while taking her breast back into his mouth. He continued to drive his hard dick into her before letting out his seed into her again leaving her with a aego face. Giving her his last order, you will keep my dick in your pussy and ride me as soon as you wake up am I understood? Yes, master Akeno said with a look of fanaticism.
He touched her, caressing her into his embrace. While sucking on his nipple like a baby.
["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.
