Ultimate Spin System: Ero Spin?-Chapter 98 - Sis is Watching!

Beatrice cried out, her nails digging into his shoulders. He began to move, his thrusts slow and deep. He could feel her tightening around him, her moans filling the room.

Lucas’s hands moved to grip Beatrice’s hips, his thrusts becoming more urgent. He could feel his release building, his need for Beatrice consuming him. He leaned forward, capturing her lips in a searing kiss.

Beatrice’s hands moved to grip Lucas’s ass, her hips bucking against him. She could feel her release building, her body tightening around him. With a cry, she shattered, her orgasm washing over her in waves.

Lucas groaned, his release following soon after. He buried himself deep inside her, his seed filling her. He collapsed against her, his breath coming in ragged gasps.

They stayed like that for a moment, their bodies still connected. Lucas could feel Beatrice’s heart pounding against his chest, her breath hot against his neck. He pulled back, his eyes meeting hers.

"Your sword is amazing, Master!" Beatrice whispered, her cheeks flushed.

"Your pussy is amazing too," Lucas replied, his voice filled with awe. He leaned in, capturing her lips in a soft kiss.

Lucas’s breath came in ragged gasps, his pulse still racing with unspent hunger. The lingering effects of [Passive Skill: MILF Enhancer] had taken their toll—his body demanded more, his mind clouded by insatiable need. He clenched his jaw, attempting to steady himself, but the hunger refused to subside.

The system wasn’t helping either.

[System Notification: Warning! Libido Threshold Exceeded! Your desire is growing beyond normal limits!]

A low growl escaped him. His body still craved more, an insatiable urge coiling in his gut like a beast refusing to be tamed. The steam in the bathhouse had long settled, but his own heat had not.

Lucas ran a hand through his damp hair, inhaling deeply.

He needed more.

And he wasn’t satisfied.

---

A few minutes earlier...

Lena’s stomach grumbled, a sharp pang of hunger twisting in her belly. She furrowed her brows, hugging her midsection as she sat on the bed. The moonlight filtering through her window cast long shadows on the wooden floor, the silence of the night amplifying the noise from her stomach.

She bit her lip.

"Ugh... why am I so hungry now?"

She had eaten earlier, but after using up so much energy during training, her body was craving more food. Then she remembered something.

"Lucas!"

Her older stepbrother always carried around that big-ass bag of supplies in his inventory, and that bag had a ton of food stored inside. If anyone had something to snack on at this hour, it was him.

Lena climbed off the bed and padded toward the hallway.

Lucas’s room wasn’t far, just down the corridor. She knocked lightly on his door.

No response.

Frowning, she tried again, this time opening the door slightly to peek inside.

Empty.

The room was dimly lit, his belongings neatly arranged, but there was no sign of him. Lena’s brows knit together. Where the hell did he go? At this time of night?

Sighing, she turned on her heel and made her way downstairs. Maybe he was in the kitchen grabbing a late-night snack himself. The wooden floor creaked softly beneath her feet as she moved carefully, the large estate eerily silent save for the occasional rustle of leaves outside.

As she reached the lower level, another discomfort hit her.

"Ugh... I need to pee too."

She changed course, making her way toward the restroom. The hallways were dark, but she had walked this path so many times she didn’t need the lights to guide her.

Pushing open the door to the women’s restroom, she slipped inside.

A few minutes later, as she finished up and was about to leave, her ears caught a faint, strange sound.

A wet, slick noise.

Followed by a soft, breathy moan.

Lena’s body stiffened.

"What... was that?"

She held her breath, straining her ears.

The sound came again—an unmistakable mixture of something wet and rhythmic, accompanied by muffled whispers.

A chill ran down her spine.

The pitter-patter of her heart grew louder, her pulse hammering in her ears.

Slowly, she cracked open the door and peered outside. The hallway was empty, the dim lanterns casting eerie shadows on the wooden walls.

But the sound wasn’t coming from here.

She turned her head.

The men’s bathhouse.

Lena swallowed, feeling a lump in her throat. Her hands gripped the hem of her nightgown as she hesitated.

She should not be investigating this.

But her feet were already moving.

Step by step, she made her way toward the bathhouse, every sound amplified by the utter stillness of the night. The wooden floor felt colder beneath her bare feet, the air thick with anticipation.

The sliding door to the men’s bathhouse was slightly ajar.

Inside, the changing area was dimly lit, steam curling at the edges of the entrance to the bathing chamber.

And there—on the bench—was Lucas’s clothing.

Lena’s stomach dropped.

"What is he doing in there...?"

She swallowed hard, her hands trembling slightly as she reached for the second sliding door—the one that led directly to the bath itself.

Her heartbeat thundered in her chest as she carefully, very carefully, pulled the door open just a crack.

The moment she did, her breath hitched.

Steam filled the room, swirling lazily in the dim lantern light.

And right there, in the middle of the bath, Lucas was moving—his body pressed against someone else.

Someone with curves.

Someone with ample flesh glistening with water and soap.

Someone moaning as he moved.

Lena’s face burned.

Her mind screamed at her to look away.

To run.

But her hands remained frozen on the doorframe, her feet rooted in place.

And her heart?

It pounded louder than ever.

Lena’s breath came in short, uneven gasps. Her body felt numb, her fingers clenching and unclenching around the wooden frame of the door as she stood motionless, eyes locked on the scene before her. She knew she should leave. She should turn away, pretend she hadn’t seen anything, push the door shut and erase the image burning itself into her mind.

But she didn’t.

She couldn’t.

Her feet refused to move. Her gaze refused to shift.

Her heart pounded erratically in her chest, an unsteady rhythm that echoed through every inch of her body.

This wasn’t the first time she had seen Lucas like this. She had caught him before—with another woman like this. But back then, she had walked in by accident. Back then, she had confronted him, and Lucas had used his Persuasion Touch on her, soothing her disbelief, convincing her that he had been seduced, that it wasn’t his fault.

And she had believed him.

She had sworn to protect him from the naughty MILFs who preyed on him. She had promised herself that she would keep him safe, that she wouldn’t let it happen again.

So why was she here now? 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

Why was she the one sneaking around, peering through the gap of the door, watching?

Lena swallowed hard, her throat dry.

This time was different.

Lucas wasn’t hesitating. He wasn’t resisting.

His movements were filled with confidence, with purpose. His hands gripped the woman with certainty, his lips tracing along her skin without an ounce of reluctance. The way he touched her, the way he moved against her—it was raw. It was primal.

And it wasn’t forced.

It was real.

It was Lucas.

And she couldn’t look away.

Heat curled in her stomach, a slow, suffocating sensation creeping up her spine. She told herself it was disgust, that it was shock or horror at what she was witnessing. But deep down, she knew.

She had always known.

It wasn’t disgust that kept her rooted in place.

It wasn’t horror that made her breath hitch, her pulse quicken.

It was him.

It had always been him.

Lena squeezed her eyes shut, willing the thought away, but the moment she opened them again, it was still there—he was still there.

Lucas.

The boy she had spent years convincing herself she saw as a brother.

The boy she had pushed her feelings for into the deepest, most hidden part of her heart.

The boy that once force her to call him Onii-chan.

The boy she loved in a way she shouldn’t.

And now, here he was.

Not as weird boy she had grown up with.

Not as the stepbrother she had promised to protect.

But as a man.

A man who didn’t need protecting.

A man who banging hard the Milf like a dog.

Her nails dug into the wooden frame, the sharp pain grounding her for only a moment before the flood of emotions surged forward again, drowning her.

She should have left.

She should have run.

But she didn’t.

Instead, she stayed.

And she watched.
