CHAPTER 40: BJ LUCY*

Caelen woke with the faint ache of a good workout still in his limbs. The morning light slanted through the curtains, warm and lazy, but he was already sitting on the bed, pulling up his status window.

[ Caelen – Status Overall ]Intelligence: 25Strength: 47Agility: 47Endurance: 26Resistance: 31DM count: 470Remaining Points: 54

His brow lifted."My stats improved?"

It had been a week since he’d started training with Lucy in earnest. Every day had been intense—sparring, magic drills, and even more sparring until both of them could barely stand. He’d expected some gains, but...

"Was that training effective?"

He tapped the next profile.

[ Lucille – Status Overall ]Intelligence: 45 → 46Strength: 52 → 53Agility: 63 → 64Endurance: 70Resistance: 46DM count: 10,010

He frowned. "Only one point in most stats?"

It wasn’t bad—Lucy’s numbers were already insane compared to his—but maybe training with someone weaker wasn’t pushing her the same way. Curious, he checked Emma’s next.

[ Emma – Status Overall ]Intelligence: 27 → 36Strength: 32 → 40Agility: 29 → 34Endurance: 27 → 40Resistance: 30 → 36DM count: 3,200

Caelen blinked."...She got stronger?"

That didn’t make sense. Emma hadn’t trained with them, not the way Lucy had. Unless...

His mind wandered back to the week they’d spent together—almost every day except one—and a very different kind of "exercise."Could it be...? Did their stats increase through that too? And if so, was it random, or did the growth match their natural strengths?

"I’ll figure it out during the next session with Emma," he muttered, leaning back.

He opened his own stat screen again and started placing his points, spreading them between endurance, intelligence, and his DM count.

[ Caelen – Status Overall ]Intelligence: 25 + 20 = 45Endurance: 26 + 20 = 46DM count: 470 + 140 = 610

The moment he confirmed the changes, a rush of warmth swept through his body. His muscles felt denser, his mind sharper, and his breathing lighter all at once. It was so overwhelming that he almost... well, reacted in another way entirely.

He exhaled slowly, letting the sensation fade. Just as he was starting to relax, there was a knock on the door.

"Come in," he called.

The door opened, and to his surprise, Lucy stepped in.

She wasn’t wearing her usual sharp expression. Something about her aura felt... softer. Warmer. Almost similar to the feeling Emma gave off, though not exactly the same.

"Hey," she greeted.

"Good morning," Caelen replied. He hadn’t expected her to seek him out—not after how distant she’d been lately. She walked over and sat on the edge of the bed, not too close, but not far either.

For a moment, she just sat there, silent.

"Is something wrong?" he asked. "Are you okay?"

"Kinda," she admitted.

"What do you mean?"

"Remember that day when I collapsed?"

Caelen nodded slowly. "Yeah. You pushed yourself too far using primordial demon energy. We still haven’t figured out how to turn that off, since it seems to replace your normal demon energy without warning."

"Right." She looked down at her hands. "We knew it was primordial energy, but... I found out something myself."

Her voice trailed off. Caelen noticed it then—a faint red glow pulsing under her blue demon skin.

"What did you find?" he asked.

She took a deep breath, as if bracing herself. "Last week, I came to this room to call you for dinner. But when I got here..." She didn’t finish.

Caelen already knew. They’d been with Emma that night, and they hadn’t heard her knocking.

"Yeah," he said carefully. "What about it?"

Lucy’s face turned a deeper shade of red. She stared at the floor, voice barely above a whisper. "I... touched myself."

Caelen froze. He hadn’t expected her to be that direct.

"I went back to my room after," she continued, speaking slower now, every word heavy with embarrassment. "When I... finished, something felt different. I tested my magic on the wall. The ice was still light blue, but... it was transparent this time."

She glanced at him, then away. "I think I’m... changing myself. Or maybe... I need to do that with you for it to work." Her blush deepened.

Caelen remembered a vague system notification from before—something he hadn’t paid much attention to. This sounded suspiciously similar.

But before he could say anything, Lucy blurted, "I’m not going to do that with you!"

A long pause followed.

"...I’m not ready," she added more quietly.

"I understand," Caelen said gently.

Her lips pressed into a thin line. "But... I’m feeling it again. The same as in the dungeon. Back then, I didn’t know what it was, so I ignored it. But now..." She shook her head. "And with all the training we’ve been doing... I’ve been using my ice magic more. I need to stop myself from collapsing again."

"This time’s different," Caelen said. "You’re awake. We can come up with another solution."

Lucy hesitated, then asked, "...What did you do last time?"

Caelen scratched his cheek. Saying it out loud felt... awkward. Instead, he reached for the book sitting beside the bed, flipped through it, and showed her the page.

Her eyes widened. "Emma did this?"

"Yeah."

Lucy stared at the page for a long moment. Her mouth opened, then closed. She muttered something under her breath—too soft to catch—but it sounded like, Come on, Lucille... you came this far. You knew you’d have to do something embarrassing.

She shook her head slightly, then whispered to herself, "I already said embarrassing stuff. Might as well not stop now."

Caelen couldn’t help it—he found her hesitation cute. He hadn’t expected her to even consider it today, but here she was, wrestling with herself.

Then she stood. Slowly.

She moved to stand directly in front of him, her posture stiff with nerves.

"You will not tell anyone about this," she said firmly. Her eyes narrowed. "Especially Emma."

Caelen raised his hands in mock surrender. "Okay."

She went down on her knees, her movements hesitant and filled with a mix of embarrassment and determination.

Caelen, watching her, could see the struggle in her eyes—the first time she had ever done something like this, especially for someone like Emma, whose memory of the experience was hazy at best.

Lucy’s fingers trembled slightly as she reached up to grasp his thighs, her voice barely above a whisper as she asked, "Why aren’t you taking it out?"

Caelen, understanding her nervousness, complied without a word. He dropped his shorts, revealing himself to her gaze.

Lucy’s eyes widened in shock as she looked up, taking in the sight of his towering rod.

It was bigger than she had imagined, dwarfing her face, and she couldn’t help but reach for the book on the bed, flipping through the pages. "Why is this bigger than in the book?" she stammered.

Caelen chuckled softly, his voice gentle. "Sizes aren’t the same for everyone. Think of it like boobs—some are bigger, some are smaller."

Lucy’s cheeks flushed a deeper shade of red, but her curiosity was piqued.

She reached out tentatively, her fingers brushing against his length before fully wrapping her hand around it.

Caelen guided her, his voice low and encouraging. "Why not touch it first? And now, grab it gently and stroke it with your hand."

Her initial hesitation melted away as she began to explore, her movements becoming more confident.

She marveled at the strange liquid that seeped from him, the strong, musky scent that seemed to awaken something deep within her.

Her own body responded, a pulsing sensation building between her legs, making her aware of her own desires.

Caelen watched her, his breath catching in his throat as he saw the change in her expression. Her eyes were no longer downcast but filled with a newfound fascination.

"Why not try licking it?" he suggested, his voice thick with desire.

Lucy’s tongue darted out, tentatively tasting him. The sensation was electric, and she couldn’t help but wonder what it would be like to take him fully into her mouth.

Unbeknownst to her, her own body was reacting, producing a scent that was both intoxicating and alluring to Caelen.

He felt a strange, tingling sensation, a mixture of hot and cold that sent shivers down his spine.

The next moment, she took him into her mouth, swallowing him whole. It was a first for Caelen, a sensation unlike any other. He felt as if he were being sucked by an alien, her blue demonic skin and crimson eyes hypnotic and mesmerizing.

"Mhmmm."The room was filled with the lewd sounds of her mouth, her loud, wet sucks and slurps echoing off the soundproof walls. It was amazing, a symphony of pleasure that threatened to consume them both.

As Lucy continued her exploration, her mouth working in a rhythm that was both innocent and incredibly skilled, Caelen’s grip on reality began to slip.

Her blue skin seemed to glow with an inner light, and her crimson eyes held a hunger that matched his own. The sounds of her mouth, wet and eager, filled the room, a symphony of desire that pushed him closer to the edge.

Caelen’s hands found their way to her hair, tangling in the strands as he guided her movements.

He could feel the pressure building, a coil of tension that promised release. Lucy, sensing his impending climax, doubled her efforts, her tongue swirling around him, her cheeks hollowing as she sucked him deeper.

The room seemed to spin, the boundaries between them blurring.

Caelen’s breath came in ragged gasps, his body tensing as he neared the ridge. Lucy, her own desire burning brightly, wanted more.

She craved the taste of him, the essence of his pleasure. Her hands gripped his thighs tightly, her nails digging into his flesh as she took him deeper, her throat relaxing to accommodate him.

With a final, shuddering breath, Caelen let go.

His climax exploded through him, a wave of pleasure so intense it bordered on pain. Lucy, her eyes locked on his, swallowed every drop, her throat working as she took him fully.

She could feel the heat of his release, the taste of him, and it ignited something primal within her.

As the last of his pleasure subsided, Lucy pulled back, her lips glistening.

She looked up at him, her eyes shining with a mix of satisfaction and a hunger for more.

"I want more," she whispered, her voice hoarse with desire. "I want to taste you again."

Caelen, still reeling from the intensity of his climax, could only nod.

His body was sated, but his mind was already racing, wondering what other pleasures they could explore together.
