Occult Research Clubroom...
"I might be mishearing things, but I swear he mentioned anti-dragon blade..." Issei muttered as he recalled the night before. The image of a blade with golden lines along the organic design surfaced in his mind.
[You didn't partner, I could feel how life threatening the sword was the moment it appeared. I don't ever want to see it again.]
"So he disappeared for a year and cameback all powerful," Issei said with a thoughtful expression, "Did he train in deep mountain and attain enlightenment or something?"
"Enlightenment? That's called being high," a voice spoke behind him, which took him by surprise. He turned around and saw Kousuke smiling at him, the latter put his arm around his shoulder.
"If you wanted to know the secret to my strength I can tell you," he whispers to his ears, bringing goosebumps on Issei's body as the latter pushed him away.
"Never do that again, I like boobs."
"You say that, but have you truly experience the 'P treatment' yet?" Kousuke muttered the key word that's only known between them with a lewd smile, Issei widen his eyes in surprise.
"Y-You don't mean...with Tsubaki-senpai?!"
"...what is 'P treatment'?" Koneko asked, her hand tugged on Kousuke's shirt as she looks up to him. Her expression remained neutral but he can tell that she was gradually opening herself to people. For once, she didn't call Issei pervert on sight, though she did gives him dirty look—an improvement nonetheless.
"Ah, you're still too young to understand, Koneko-chan~" Kousuke said while rubbing the top of her head with a smile, she pout at his dismissal. "I'm...old enough."
"Well if you say so, it's Pai—" "Oppai!"
Issei shouted out loud before he could say the word. But when Issei realized Kousuke never planned to say it, seeing the smirk on his face. He had fallen into a trap! He saw how Rias was staring at him with deadpan expressions, and Akeno with bemused smile.
"Objection, Your Honour! I had been set up! I'm innocent!"
"Objection denied!" Rias said with a sigh, arms crossed, clearly used to this sort of nonsense by now.
Kiba chuckled from the sofa. "I think the court of public opinion has already found you guilty, Issei."
"I'd like to appeal!" Issei protested, but no one listened.
Meanwhile, Akeno leaned in slightly toward Kousuke, her eyes narrowing with playful curiosity. "My, my. You certainly know how to stir up a room."
Kousuke grinned in return. "I live to entertain."
Koneko, still holding onto his sleeve, gave a suspicious squint. "You still haven't explained what the 'P' stands for."
"It's short for 'Pillow talk,'" Kousuke said without missing a beat, ruffling her hair again. "Something you'll understand when you're older."
Koneko narrowed her eyes, not believing his words at all. "Liar."
Issei, finally recovering, leaned forward with a serious expression. "Hold on—did you actually get the 'P treatment' from Tsubaki-senpai or not?!"
Kousuke smirked. "Well..."
...
Flashback — Kuoh Park, late night.
After the battle, instead of following the others back, Tsubaki had quietly tugged Kousuke's arm and led him in a different direction. No words were exchanged until they arrived at the quiet, moonlit park near the riverbank. The sound of water trickling nearby added a gentle rhythm to the silence.
She sat on a bench, and after a long moment, he joined her. The stillness between them lingered.
"Do you realize how reckless you were?" she finally asked, her voice quiet but firm. She didn't look at him—only stared ahead, eyes dim behind her glasses.
"I handled it," he said calmly, leaning back on the bench with his arms resting on the backrest.
"That's not the point," she snapped, more sharply than usual. She turned toward him then, brows furrowed. "You jumped into something that none of us understood. What if something had gone wrong? What if you were hurt? Or worse?"
Kousuke glanced at her—then at the moon.
"I couldn't ignore it," he replied simply before sighing. "Old habits die hard, I guess. Back there... I felt like I was still a Hero. Someone who helps when they can."
Tsubaki frowned, her voice dropping again. "And what about us? About me? Are we just supposed to stand by and hope everything turns out fine every time you act on instinct?"
He didn't reply right away. The truth was, he hadn't felt in danger at all. Freed had been too weak to even scratch him. It hadn't been a real fight—more like a warm-up, a way to test the limits of his "normal form." But he didn't say that.
Instead, he met her gaze with a small, apologetic smile. "I'm sorry for making you worry."
Tsubaki sighed, her frustration slowly melting into something softer. "You're an idiot."
"Yeah," he chuckled, "I've been told that before."
Tsubaki's eyes gleamed with a sudden, mischievous idea as she slowly stood, deliberately removing her glasses. He blinked up at her, caught off guard by the subtle shift in her demeanor. Her cool composure melted into something far more dangerous and enticing.
Before Kousuke could even utter a word, his girlfriend leaned in close, her voice dropping to a husky whisper that sent shivers down my spine. "Since it doesn't feel like you're really listening... I'm going to punish you~"
With that, she sank to her knees before him, her eyes never leaving his. In one fluid motion, her hands reached up and tugged his pants down, revealing his softening cock. He gasped as the cool air hit his sensitive flesh. Without hesitation, she wrapped her slender fingers around his shaft, stroking it slowly as she stuck out her small pink tongue. He watched, transfixed, as she licked the tip teasingly, her eyes still locked onto his.
"Ooh, how is this a punishment?" Kousuke groaned, his hips bucking slightly into her touch. Tsubaki just smirked, a wicked glint in her eye.
"I will decide that~" She purred, before pulling her shirt up and over her head. The black lace of her bra was revealed, and with a deft flick, she unclasped it. His eyes widened as she placed his quickly hardening cock between the soft, pillowy flesh of her breasts.
"Enjoying yourself?" She asked coyly, before beginning a slow, sensual titjob. Her tongue flicked out to lick the tip each time it peeked out from her cleavage, sending electric shocks of pleasure through his body. Kousuke could only moan in response, completely at her mercy.
As Kousuke lay there, lost in a haze of pleasure, Tsubaki continued her sensual assault. Her tongue swirled around the head of his cock, tracing the ridges and veins with deliberate slowness. Each flick and lick sent bolts of electricity through his body, making him squirm with need.
Tsubaki could feel Kousuke's cock throbbing against her breasts, growing harder and more insistent with each passing second. She could tell he was getting close, his breathing growing ragged and his grip on the bench tightening. But she wasn't ready for this to be over just yet.
With a wicked grin, Tsubaki pulled back, allowing Kousuke's cock to slip from her cleavage. Before he could protest, she wrapped her lips around the head, sucking hard as her tongue continued its relentless teasing. Kousuke let out a guttural moan, his hips bucking up off the bench as he tried to push more of his length into the wet heat of Tsubaki's mouth.
Tsubaki hummed around his cock, the vibrations adding to the overwhelming pleasure. Her hand pumped his shaft in time with her sucks, twisting and squeezing in a way that had Kousuke seeing stars. He tangled his fingers in her silky hair, guiding her head as she bobbed up and down his throbbing length.
"Fuck, Tsubaki... I'm gonna fucking come!" Kousuke grunted, his voice strained with pleasure. His blue ocean eyes squeezed shut as he felt the telltale tightening in his loins, signaling his impending release.
Tsubaki didn't miss a beat. She doubled her efforts, sucking harder and faster, her head bobbing up and down his throbbing shaft with renewed vigor. Lewd, wet sounds filled the air as she slurped and suckled, the obscene noises echoing through the quiet park.
Kousuke's grip on her hair tightened, his fingers tangling in her silky locks as he fought to hold back his climax. But it was no use. With a guttural moan that seemed to reverberate through his entire being, Kousuke felt his cock pulse and twitch before erupting like a volcano.
Thick, hot ropes of semen shot down Tsubaki's eager throat as she swallowed greedily, not wanting to waste a single drop of her lover's essence. Kousuke's body shuddered and convulsed with the force of his orgasm, his tall, muscular frame nearly lifting off the bench.
Wave after wave of pure, unadulterated bliss crashed over Kousuke as he rode out his high, his heart pounding in his chest like a drum. Tsubaki continued to suck and swallow, milking him for every last bit of his release until he finally collapsed back onto the bench, completely spent and satisfied.
As the last waves of Kousuke's intense orgasm subsided, Tsubaki slowly pulled her mouth away, a satisfied smirk playing on her glossy lips. She licked them slowly, savoring the taste of his essence that still lingered. Rising gracefully, she crawled up Kousuke's body until she straddled his hips, her bare breasts pressing against his heaving chest.
Kousuke could only stare up at her, his blue ocean eyes glazed over with post-orgasmic bliss. He was still trying to catch his breath, his heart pounding like a drum in his chest. Tsubaki's 'punishment' had been far more pleasurable than he could have ever imagined, leaving him completely at her mercy.
Tsubaki leaned down, her lips brushing against Kousuke's ear as she whispered, "I hope you enjoyed your punishment, Kousuke. But don't think we're done yet~"
With that, she reached down between their bodies, guiding Kousuke's still-sensitive cock to the entrance of her dripping sex. Despite his recent release, he could feel himself starting to harden again at the thought of what was to come.
Tsubaki slowly sank down, taking him inch by inch into her tight, wet heat. Kousuke gasped, his hands flying to her hips as he tried to hold her still. The sensation of her walls clenching around him was almost too much to bear, and he knew he wouldn't last long if she kept this up.
But Tsubaki had no intention of stopping. She began to ride him with slow, sensual rolls of her hips, her breasts bouncing with each movement. The moonlight cast a soft glow on her skin, highlighting the curves and planes of her body as she moved above him.
...
Recalling the heated night that had stretched until dawn, Kousuke let out a wry smile. If he didn't have such ridiculous stamina, it might've ended badly for him.
He hadn't expected Tsubaki to be such an insatiable beast.
It was like something inside her had switched after their first night together at the love hotel. Not that he was complaining—being desired like that by someone you care about? He wouldn't trade it for anything.
As he glanced at Issei, who was watching him with an expectant look, Kousuke narrowed his eyes.
"Well... nothing," he said with a smirk. "As if I'd tell you that."
"What the hell!"
