High School DxD:Milking System World

Jin told Murayama that he would like to spend some time with her tonight as his reward. Meanwhile, he asked Katase to accompany his brother—or vice versa—to show her that Issei had indeed changed. Or so he claimed.

In truth, Jin's goal was simple: to make Issei forget about the so-called "Yuuma-chan" and bond with a more trustworthy girl. Katase seemed like a good match—she was pure and untainted by malice. Even when faced with Jin's natural charm, she had refused to do anything lewd, which impressed him.

Not to boast, but Jin was confident in both his looks and charisma—making it rare for a girl to refuse his advances. He wanted Issei to date someone like Katase—someone kind-hearted and grounded. Plus, considering they'd likely see each other often if Katase became Issei's girlfriend, it seemed like the perfect setup.

Kuoh Academy - After School

After Murayama finished explaining to the other Kendo Club members what had happened, Jin waited patiently. Issei and Katase had already left, as Issei offered to walk her home—a perfect opportunity for them to bond.

Meanwhile, the other Kendo Club members couldn't hide their excitement, giggling and whispering as they watched Jin from afar. The rumor that he had stood up for Issei had already spread, boosting his popularity even more.

When everything was settled, Jin waved goodbye to the remaining club members and left the school with Murayama by his side.

She had changed from her hakama into her school uniform, and as they walked together, her cheeks remained flushed red the entire time. Thoughts of what might happen tonight swirled in her mind, making her both nervous and excited.

'W-Wawawa… D-Did he hear what I mumbled earlier? Is that why he asked me to come with him?' Murayama glanced at Jin shyly.

Sensing her gaze, Jin looked at her with a calm smile.

"What's wrong?" he asked.

"N-Nothing!" Murayama stammered, quickly looking down to hide her embarrassment.

Her heart raced as she recalled her words from earlier in the dojo—the ones she hadn't meant for anyone to hear. Just the thought that Jin might have heard her made her cheeks burn hotter.

Jin found her shy behavior adorable and chuckled softly as they continued walking.

Soon, they arrived at a familiar location—the park where Jin had milked Aika just two days ago. The timing was perfect; the sun had already set, and the park was empty, providing the privacy he needed.

"We're here," Jin said, stopping in front of the park entrance.

Murayama looked up in surprise.

"A park?" she asked, tilting her head.

"Yes. Don't you think it's the perfect place for a quick date, Murayama?"

"D-Date?!" Murayama's eyes widened as her heart skipped a beat. "Y-Your wish was… to go on a date with me?"

Jin smiled mysteriously, placing his index finger in front of his lips.

"…And more. Come on, I promise you'll enjoy it."

Murayama's face burned even hotter at his words, but she nodded obediently, unable to resist the excitement that tingled through her body.

Inside the Park

Jin led Murayama to a secluded area, hidden among the trees where no one would disturb them. As they walked, he silently activated Lactation Fog, filling the air around them with its invisible effects.

This time, he was confident in using his skills without fear of detection. The day before, he had conducted an experiment while Issei's girlfriend, Amano Yuuma, had been at their house. Jin had activated his Milking Room and other skills to see if she could sense them—she hadn't.

That experiment had proven that his abilities could be used discreetly. Moreover, he had discovered that he could activate his skills without vocal commands—merely thinking about them was enough.

'Good. This means I can use my skills freely without worrying about anyone noticing.'

Jin sat down on a bench in the secluded area, then gestured for Murayama to sit beside him.

She hesitated briefly, her heart pounding in her chest, before taking a seat next to him. The air felt strangely warm, and her skin tingled slightly as a faint heat began to build inside her.

"Murayama," Jin began, turning toward her. "You came with me so obediently… That means you already know what my wish is, right?" His tone was soft but carried a hint of playful mischief.

"U-Um…" Murayama bit her lip nervously before nodding. "I-I'm ready for anything… If it's you, Jin-kun, then I don't mind."

Jin smirked slightly, leaning a little closer.

"Look at you," he teased. "Calling my brother a pervert when you're the one asking me to do lewd things. Didn't you say something like that back at the dojo?"

Murayama's eyes widened in shock, and her face turned crimson.

"B-But… You don't want me?" she whispered, her voice trembling as she looked up at Jin with pleading eyes.

"I never said I didn't," Jin replied with a chuckle.

The effects of the Lactation Fog were starting to show—Murayama's breathing had grown heavier, and her skin flushed with a faint pink hue. While the fog's aphrodisiac effect wasn't overpowering, it was enough to stir her desires, making her more receptive to his touch.

Reaching out, Jin gently tilted her chin upward with his fingers, bringing their faces close.

"Can I kiss you, Murayama?" he asked softly.

"Yes…" she whispered.

Without hesitation, Jin closed the distance, capturing her lips in a tender kiss.

As their lips met, Jin activated the Milking Room in his mind.

[Milking Room Activated]

[You have 30 minutes before the room automatically disappears.]

[Happy Milking, User.]

The air shifted subtly as they were transported to the Milking Room. However, thanks to Jin's practice, he had altered the room's appearance to mimic the park's surroundings—trees, grass, and even the bench beneath them appeared identical to the real world.

This time, Jin had hidden all the sex toys and equipment, leaving only a clean, natural environment. However, he could summon any tool he desired with just a thought.

Murayama, lost in the kiss, didn't notice the change at all.

Jin broke the kiss first, pulling back just enough to leave a thin trail of saliva connecting their lips. Murayama gazed at him with half-lidded eyes, her breath coming in soft, heated gasps.

"I'm going to milk you now, Murayama," Jin whispered. "Just relax and enjoy it, okay?"

Murayama's mind was clouded with desire. The warmth spreading through her chest and the tingling sensation from the fog made her crave his touch. Though she didn't fully understand what Jin meant by "milking," her aroused state left her eager to obey.

"Yes… Please… Milk me… Milk me hard…" she whimpered.

'Perfect.' Jin thought with a smirk.

Placing his hands on Murayama's chest, he activated Golden Hand, his fingers expertly massaging her breasts through her uniform.

"Ahhn~!" Murayama moaned softly as waves of pleasure coursed through her body. Her back arched instinctively, pressing her chest into Jin's hands.

The fog's effects had already stimulated her lactation, and with each squeeze and knead of his skilled hands, the pressure in her breasts began to build. Murayama clung to Jin's shoulders, biting her lip to suppress her moans as her arousal intensified.

"D-Don't stop… P-Please, don't stop…" she pleaded breathlessly.

Jin smirked as he continued his skilled massage, feeling the faint warmth beneath her uniform as her body responded eagerly to his touch.
