Ultimate Spin System: Ero Spin?-Chapter 108 - Danger

Lucas stiffened, lowering the towel from his face. "What?"

Lena shifted uncomfortably, her gaze flicking away before snapping back, her expression unreadable. "You heard me," she said, voice steady despite the pink dusting her cheeks. "When we get back to the real world, you have to be my boyfriend."

Lucas’s brain stalled.

His lips parted, but no words came out.

Did she just—?

His heart lurched in a direction he wasn’t ready for. He studied her face, searching for any sign that she was joking, but Lena’s expression was completely serious.

She wasn’t messing around.

"You—hold on," he finally forced out. "Where is this coming from?"

Lena tightened the towel around herself, exhaling sharply. "I don’t know, okay?" she admitted. "I just... I can’t pretend that this didn’t happen. That we didn’t—" She cut herself off, shaking her head as if clearing a thought she wasn’t ready to face. "I need to know that this meant something. That you’re not just going to brush it off like it was nothing."

Lucas swallowed. His pulse hammered against his ribs, a sick mix of confusion and unease tightening in his gut.

This wasn’t right.

Not because he didn’t want her—because God, that would be a lie—but because... they were step-siblings.

And worse than that...

He had already crossed a forbidden line before.

A different kind of tension seeped into his veins at the memory of his big booty stepmother—her touch, her whispers, the things they had done behind closed doors. It had been reckless, dangerous, but even then, he had told himself he had control over the situation. That it was just indulgence.

But this?

Lena wasn’t just some fleeting mistake.

She was his stepsister. His responsibility.

And now she was looking at him like this—expecting something from him that he didn’t know if he could give.

Lucas let out a slow breath, dragging a hand down his face. "Lena, we—we should think about this."

She frowned. "What’s there to think about?"

"We’re... family," he said, the word foreign in his mouth.

Lena scoffed. "Barely."

That should have made it easier.

It didn’t.

Lucas clenched his jaw, staring at the flickering shadows on the cave walls. He couldn’t shake the unease crawling under his skin. Something about this whole situation felt off. He just couldn’t figure out why.

But Lena wasn’t waiting for him to make sense of it.

"You can think all you want," she said, voice quiet but firm. "But my answer won’t change."

Lucas swallowed hard.

The rain continued to pour outside, drowning out the sound of his thundering heartbeat.

As night fell, the storm finally began to wane, the heavy downpour fading into a light drizzle. The rhythmic patter of water dripping from the cave’s entrance echoed in the stillness, but the tension between them remained thick, unresolved.

Lucas exhaled, rubbing a hand over his face. Their clothes, though no longer drenched, were still damp and clung uncomfortably to their skin. He shifted, reaching for his bag, pulling out a spare shirt and slipping it over his head. The fabric was cool against his skin, but at least it was dry.

Lena, seated a few feet away, had also changed into her clothes, now slightly damp but wearable. She pulled her knees to her chest, staring at the dying light outside, her expression unreadable. Lucas knew she was still thinking about what she had said earlier.

You have to take responsibility.

The words echoed in his mind, but he shoved them aside. Now wasn’t the time.

Instead, he turned his focus elsewhere, scanning the cave interior. They needed warmth. His gaze landed on a thick, sturdy branch wedged between some rocks near the entrance. He stood, stretching the stiffness from his limbs, and walked over to pry it free.

"Hey, what are you doing?" Lena asked, glancing at him.

"Getting firewood," Lucas replied, hauling the branch back toward the center of the cave. "It’ll get too cold if we don’t have something to keep us warm."

Lena watched as he set the wood down, rubbing his hands together. "Do you even know how to start a fire without matches?"

Lucas smirked. "Lucky for us, I don’t need matches."

He stretched his fingers, focusing on the familiar tingling sensation of magic flowing through his veins. Activating Elemental Imbuement (Fire), his fingertips glowed with a faint orange hue before a small flicker of flame formed in his palm. Carefully, he pressed his hand against the base of the wood, and within moments, the fire caught, spreading across the branch until a steady flame flickered before them.

The warmth instantly seeped into the air, chasing away the lingering dampness.

Lena blinked. "You never told me you could do that."

Lucas shrugged. "Never came up."

She rolled her eyes but inched closer to the fire, extending her hands toward the warmth. The silence stretched between them, more comfortable now, the flickering flames casting long shadows along the cave walls.

For the first time since the storm began, Lucas felt like they could finally breathe.

But then—

A deep, guttural roar shattered the quiet.

Both of them froze.

The sound was distant yet powerful, reverberating through the air like a beast announcing its presence.

Lena’s eyes widened. "What was that?"

Lucas was already on his feet, instinctively reaching for the dagger strapped to his waist. His muscles tensed as he moved toward the cave entrance, carefully peering out into the darkness beyond.

The rain had stopped completely, but the night was thick with mist, curling around the trees like ghostly tendrils. The forest beyond was eerily still—except for the heavy rustling of leaves in the distance.

Another roar—closer this time.

Lucas cursed under his breath.

"Something’s out there," he murmured.

Lena stood as well, her body tense. "Do you think it’s dangerous?"

Lucas glanced at her, eyes sharp. "A roar like that? Definitely."

For a moment, neither of them spoke, listening intently. The fire crackled softly behind them, casting warmth against their backs, but outside—something big was moving through the trees.

And it was getting closer.
