A wet, rhythmic sound echoed from the place where their bodies met, as though water were being churned. Cassion hooked one of her legs over his arm while he pressed his other hand firmly against her lower abdomen.

“Ha… can you feel it here?”

“Mmh…”

“When I move inside you, it reaches even to my palm.”

The thin skin of her lower abdomen quivered beneath his hand. More precisely, it moved with each thrust of his hips. He had not entered her completely yet, but he was deeper than before. Each time he moved inside her, her abdomen lifted and trembled in response.

“Mm… ah… ha…”

“It seems your cl*toris still gives you the most pleasure.”

Every time he pressed his thumb against her sensitive bud, steadying her stomach with his other hand, her inner walls tightened around him. The sounds slipping from between her parted lips became sweeter and more helpless.

Recalling that patience and persistence were required to give a woman pleasure, he pressed the tip of his p*nis firmly against her most sensitive spot while flicking her cl*toris with his thumb.

“Ahh—!”

Although it was night-time, the room felt flooded with sunlight. Lunaria’s mind was swimming in a haze and every nerve was ignited wherever he touched her. The heat burning inside her was almost unbearable yet she was still unsatisfied.

She panted with pleasure from her swollen, reddened cl*toris. A cry burst from her lips and, at that same instant, he thrust deep inside her, pressing insistently against her core. A sharp, curling sensation shot through her toes in waves of sweet, electric pleasure.

“Hnng—!”

Before she could tell which sensation overwhelmed her more, he lifted her legs and draped them over his shoulders. Then, with a faint chuckle, he asked:

“Is there a reason you’re holding your tail?”

“…What?”

Cassion struggled to suppress his laughter at the sight before him.

Pinned beneath him, Lunaria had carefully drawn her tail into her bound arms and was holding it close to her as though it were precious.

With her wrists still tightly tied with the sash, she could not move her hands freely. Yet, in that position, she had pulled her tail into her embrace.

How could that not be endearing?

He longed to stroke her soft, black fur, which was like her hair, but something else demanded his attention more urgently.

“Ha… Luna.”

He braced his arms on either side of her face. The veins on the backs of his hands and forearms stood out starkly as he pressed into the bedding. He stretched his legs back and lifted his hips high.

“Shall we try going deeper this time?”

“…Yes.”

Still holding his tail tightly against her chest, she could not take her eyes off Cassion, who was standing so close to her. He had always spoken to everyone in the same formal way, so when he lowered his tone just for her, nothing else in the world seemed to matter.

It was only a subtle change in his speech, yet the space around him seemed to tremble with it.

She was unbearably happy.

Happy to spend her life with him. Happy that he only relaxed in her presence.

Gazing up at him as though nothing else existed, she barely noticed when he entered her with sudden force.

“Hngh—!”

The downward thrust was powerful. Pinned beneath him, her body trembled uncontrollably. Folded and pliant beneath his weight, she felt as though she might be pressed straight into the bedding itself.

“Ah—ngh—!”

Each time he thrust inside her, broken moans escaped her lips. A sharp, electric pleasure flared up from deep within her. The sweetness she had previously experienced naturally resurfaced, intertwining with the sharper sensation inside and the memory of his subtle pressure against her cl*toris.

“Ahh…”

“Mm.”

Cassion groaned softly at the way her inner walls rippled around him. Each time his p*nis pressed firmly against her deepest point, her body tightened and grew hotter. The sweetness of her voice deepened further and a heavy sensation coiled in his abdomen.

“Ha…”

As though praising her for slowly learning how to feel him from within, he thrust harder.

“Ahh—!”

When she finally took him in completely, her inner walls spasmed once more. Although she was trembling, the sensation of her drawing him in was overwhelming.

Bending his knees, he cradled the back of her head, pressing their bodies together and moving within her with unrestrained rhythm.

“Ah—ah—ngh—”

“Hah…”

He breathed heavily as he thrust with slow, deliberate force. He felt her soft chest pressed against his as he wrapped an arm around her back, pulling her close and leaving no space between them. Burying his face in the pale curve of her neck, he moved more insistently.

Her warmth yielded to him, pliant and enveloping wherever he touched her. No matter how he moved, she welcomed him, drawing him in further.

His rhythm quickened, the bed creaking faintly beneath their combined weight. If anyone had been below, they might have heard.

Cassion moved with the full weight of his body. The moment she tightened around him, he released the restraint he had been holding back.

A low sound slipped from his lips.

For a fleeting moment, it felt as though they were joined, with no possibility of separation. He could feel the heat between them in vivid detail — how it gathered and held him close.

“Ahh…”

Lunaria trembled, holding her hands weakly against her chest. She welcomed the warmth spreading through her body. With an effort, she lifted her relaxed legs and wrapped them around his waist, instinctively pulling him close as though she was unwilling to lose a single drop.

“Ha… it’s still not enough, is it?”

He turned his head slightly and whispered in Lunaria’s ear. This alone caused her to tighten around him instinctively. In response, he ran his tongue along the rim of her ear, breathing warmly against her skin.

“Look at this… it seems you’re still begging for more.”

“Ca—Cassion… m-more, please…”

A low laugh vibrated in his throat at her plea.

“With pleasure.”

Slowly straightening his upper body, he caught her wrists and called toward the door.

“Gael, are you there?”

An answer came at once from outside.

“Yes, Master.”

“Bring fruit and cool water.”

“At once.”

The sun had long since risen, so it was only natural that the head butler had arrived. Without further instruction, Gael adjusted the Grand Duke’s schedule accordingly.

Having attended to the Grand Duke more closely than anyone else, Gael knew exactly who mattered most to him. In truth, Gael felt quietly relieved that Lunaria remained at his side.

Sixteen years had passed since he was sent by imperial command to serve the Grand Duke. Despite having served him since his youth, the depths of the Grand Duke’s heart remained impossible to fathom.

There was something almost uncanny about him. He had never allowed anyone to get close.

No one, that is, except Lunaria.

Even so, there were aspects of her that Gael did not fully understand. But he did not show it. His duty was simply to obey his master.

“Luna, shall we practice feeling it with your chest this time?”

Cassion untied the sash that had been binding her wrists. Taking each wrist in turn, he gently rubbed them to soothe the marks left behind.

Then he took her hands in his and guided them to her br*asts. He positioned her palms so that she could cup them from below and press her thumbs against her n*pples.

The moment she did so, the part of her that was still connected to him quivered faintly.

“Hng…”

“You learned this last time, didn’t you? That it feels good when you roll them like this.”

“Yes…”

Her speech was slurred from the repeated peaks of pleasure she had experienced. She had no strength in her lips or body. She simply moved as he guided her.

“If you pinch the n*pple with your fingertips like this…”

As he spoke, he moved her hands, placing his fingers over hers to show her how to grasp and tug gently.

Sitting upright and looking down at her, Cassion watched.

Meeting his gaze, Lunaria followed his instructions, pinching her own n*pple as he had shown her.
