The first time you saw Nautilus, the Hisuian Goodra, you were captivated by his unique elegance. His bronze shell shimmered under the muted light of the Hisui region, a stark contrast to the misty, rain-soaked landscape. His large, soft eyes, the color of the deep green grass, gazed at you with a mix of curiosity and trust. His long, slick body moved with a fluid grace, even as the weight of his heavy shell seemed almost too much for him to bear. Yet, there was a strength in him, a quiet resilience that drew you in.

You had journeyed far to the Hisui region, eager to study the ancient forms of Pokémon that had long since vanished in modern times. As a young researcher with a deep love for Dragon-types, you felt an instant connection to Nautilus. From the moment you captured him, a bond formed—one that felt as natural as breathing.

At first, Nautilus’ clinginess was endearing; typical even, for his species. He would follow you everywhere, his large, liquid eyes tracking your every move, never allowing you out of his sight. Whether you were cooking, gathering resources, or even trying to sleep, Nautilus was always there, close and watchful. If you moved to another room, he would slither behind you, his damp, warm body brushing against your leg or arm whenever possible. It was overwhelming at times, but you found comfort in his constant presence. His affection felt like a warm, protective embrace, and you quickly grew attached to him.

The Hisui region was vast and wild, its dangers lurking in both the Pokémon and the untamed environment. Nautilus became your protector, always ready to defend you from any threat. In battles, he would place himself between you and your opponent, his massive shell a shield that deflected even the fiercest attacks. His retaliations were swift and powerful, leaving your enemies reeling. With each passing day, your bond grew stronger, and soon, you couldn’t imagine your life without him.

But as the days turned into weeks, and the weeks into months, Nautilus' behavior began to change.

You first noticed the change in small ways. Nautilus would nuzzle you more often, his soft, pliant body pressing against yours as he made soft, cooing noises that you interpreted as expressions of deep affection. When you stroked his head or patted his side, he would close his eyes in contentment, leaning into your touch and lingering there far longer than before.

At night, it became impossible to sleep without Nautilus curling around your bed, his massive body enveloping you in a cocoon of warmth and safety. If you ever tried to gently push him away to sleep alone, he would whimper, a sound so heart-wrenching that you couldn’t help but pull him back close.

As the days passed, you began to notice how the other Pokémon in your team kept their distance. They seemed to sense something in Nautilus’ presence that made them wary. It wasn’t outright aggression, but a sort of possessiveness that hung in the air whenever he was around. You noticed it too, but dismissed it, attributing it to his natural protectiveness. After all, you had been through so much together—was it so wrong for him to want to keep you safe?

But soon, Nautilus’ affection grew more intense. He began to seek out your attention constantly, even when you were busy or needed space. If you spoke to another Pokémon or spent time on your research, he would interject himself, slithering between you and whatever else was demanding your attention. At first, you found it cute—a sign of how much he cared for you. But gradually, it became harder to manage.

One evening, as you sat by the campfire, writing notes in your journal, Nautilus nudged your hand with his head. You smiled and petted him absentmindedly, but he persisted, pushing your journal away with his nose.

"Nautilus, not now," you said softly, trying to refocus on your work.

But he whined, a low, keening sound, and nudged you again, harder this time.

You sighed, setting your journal aside. "Alright, alright. Come here."

Nautilus immediately curled up beside you, laying his head on your lap. You stroked him gently, feeling the cool dampness of his skin. The fire crackled softly in the background, and for a moment, you felt at peace. But then you noticed the way Nautilus’s eyes were fixed on your face, unblinking, as if he were trying to memorize every detail of your expression.

You shifted uncomfortably. "You’re being silly, Nautilus," you said, though your voice lacked conviction.

But Nautilus didn’t move, his gaze never leaving yours. The intensity of his focus made you feel strangely exposed, as if he could see into your very soul.

The days grew shorter as winter approached, and the Hisui region became shrouded in a perpetual, icy mist. You found yourself spending more time indoors, seeking shelter from the harsh weather. Nautilus, as always, was by your side, but his behavior had grown even more intense.

It wasn’t enough for him to just be near you; he needed to be the center of your world. If you so much as looked at another Pokémon or spoke to someone else, Nautilus would grow restless, and he would immediately insert himself between you and whatever was capturing your attention.

You tried to brush it off, telling yourself that it was just a phase, that Nautilus was simply more attached to you than the average Pokémon. But deep down, you knew something was changing—something that made you uneasy.

It became especially apparent whenever you had to go into town. The small village at the edge of the forest was where you gathered supplies and exchanged information with other researchers. Nautilus despised these trips. As soon as you prepared to leave, he would grow agitated, his eyes narrowing with a mix of fear and anger. He would wrap himself around you, his grip tight and unyielding, as if trying to prevent you from leaving.

When you finally managed to pry him off and set out for town, he would follow closely, his massive form causing quite a stir among the villagers. People would stop and stare, some in awe, others in fear, as Nautilus plodded protectively at your side. His eyes never left you, and if anyone dared to approach or speak to you, he would let out a low, warning growl, his body tensing as if ready to strike.

Conversations became strained, as people noticed the way Nautilus hovered, his presence a constant, oppressive shadow. They would give you wary glances, their words faltering under the weight of his gaze. You tried to reassure them—tried to reassure yourself—that Nautilus was just being protective. But as time went on, even you began to feel the strain.

One evening, as you lay in bed, Nautilus curled around you as usual, you found yourself unable to sleep. The weight of his body felt oppressive, his presence suffocating. You shifted uncomfortably, trying to find some space, but Nautilus tightened his grip, pulling you closer.

"Nautilus, please," you whispered, your voice breaking. "I need space."

But he only held you tighter, his eyes glowing softly in the darkness. You could feel his breath on your neck, warm and moist, and you shivered—not from the cold, but from a realization that had taken root deep inside you.

Nautilus’ love for you had become something darker, something you didn’t know how to handle. It was no longer just affection—it was obsession. And it was consuming you both.

The turning point came on a day when you had to visit the village alone. You needed supplies that were crucial for your research, and Nautilus, sensing your impending departure, grew increasingly distressed. He slithered around you, blocking your path, his eyes pleading, desperate.

But you had to go. Gently but firmly, you pushed him aside and made your way to the village. Nautilus followed you to the edge of the forest, but this time, you told him to stay. He whined, a heartbreaking sound that tugged at your resolve, but you held firm.

As you walked away, you felt his gaze burning into your back, an invisible tether pulling at your heart. Even as you reached the village, you couldn’t shake the feeling that Nautilus was watching, waiting.

Inside the village, you tried to focus on your tasks, but it was impossible to ignore the growing anxiety gnawing at you. Every conversation felt strained, every interaction tinged with the awareness of Nautilus’ absence—and the knowledge that he was waiting, just beyond the trees.

When you finally returned, you found Nautilus exactly where you had left him on the edge of the forest. His massive form was coiled tightly within his shell on the damp earth, eyes fixed on the path you had taken. The moment he saw you, his eyes widened with relief, and he surged forward, his massive body undulating with surprising speed. Before you could say a word, Nautilus had wrapped himself around you, pulling you into a frantic embrace, his hide slick and cool against your skin.

"Nautilus..." you began, but your words were cut off as he nuzzled your neck, his breath hot and ragged. His grip was tighter than ever, and your initial relief quickly turned into a mix of emotions—happiness, guilt, and a creeping unease that you couldn’t quite shake. You reached out to pet him, your hand gently brushing over his smooth head. He nuzzled into your touch, his eyes closing in contentment, but the pressure of his grip never loosened. If anything, it grew tighter, his body coiling around you with a strength that left you breathless.

You tried to shift, to create just a bit of space, but Nautilus’s embrace was unyielding. You could feel the tip of something hard pressing into your belly, but you couldn’t see what it was. Despite the discomfort, you continued to stroke his head, hoping to soothe him. “It’s okay, I’m here now,” you whispered, trying to ignore the growing slickness against your chest.

Nautilus responded with a series of affectionate nuzzles, his large, round head pressing against your cheek, then your neck, leaving a trail of warm, wet licks in his wake. His breath was hot against your skin, and you could feel his heartbeat—echoing through his body and into yours. But even as he lavished you with affection, he wouldn’t let go.

You glanced up at Nautilus, your gaze meeting his. His eyes, usually so soft and gentle, were now filled with an intense emotion that you couldn’t quite decipher. It was as if he was trying to convey everything he felt in that single look—his love, his relief, and something deeper. You opened your mouth to speak, to reassure him, but the words caught in your throat.

Suddenly, Nautilus’ horns curled. His entire body shook, a deep, involuntary shudder that coursed through him and into you. His eyes remained fixed on yours, unblinking, wide, and filled with something akin to desperation. You could feel the tremors intensify, his hold tightening further, that hardness against your belly suddenly growing wet.

“Nautilus,” you said softly, trying to keep your voice steady, though your own heart was beginning to race. “Are you okay?”

But he didn’t seem to hear you. His trembling grew more violent, and he began to rock back and forth, his grip tightening with each sway. The keening noises started then—low, soft sounds that sent a strange flutter in your chest. It was a sound not of mourning or fear or anguish… but of deep, intense pleasure.

You realized with a jolt that Nautilus’ member was now fully erect, having snaked its way from between your bellies, the smooth tip poking against your neck. Shock washed over you, sharp and cold. Did he realize what was happening? Could he tell? Looking into his eyes, they appeared to be glazed, as if Nautilus was lost in his own haze.

He continued to rock his body against yours, that slick appendage sliding against your skin, twisting this way and that as it searched for an entrance that wasn’t there. You wrapped your own shaking hands around the thrashing member; mostly to avoid having your eye put out by its constant motion. This action only further spurred Nautilus, however, who gave another low whine, his body continuing to shake and rock, the keening sound rising and falling in rhythm with his cock sliding between your palms. His eyes never left yours, as if he were searching for something in your gaze.

Slowly, as you continued to hold him, Nautilus began to breathe more deeply. The rocking slowed, and Nautilus gave one final push against you. His member pressed tightly against your body, trembling. Tipped over the edge during this long, continuous thrust, finally, he let out a long, shuddering sigh. At once you felt warm, sticky cum pour from the tip of his cock onto your body. It did not pulse out in jets the way you were expecting; rather it oozed out continuously like a tilted molasses jar. Nautilus kept his cock pressed against you, his hips quivering as he held his position and released. Pretty soon your shirt was thoroughly drenched, with plenty more thick dragon seed running down to coat the rest of you. His grip on you loosened, just a fraction, and you could feel the tension draining from his body, leaving him limp and exhausted in your arms. Panting softly, the Dragon-type leaned against you, the steady ooze from his breeder slowing to a small trickle.

You didn’t move, afraid that any shift might disturb him. Instead, you just held him, your fingers gently stroking his soft skin, your heart thundering with the knowledge that something had changed between you. You had just done something that was unimaginable as a trainer—and you had done it to your own Pokémon.

As Nautilus finally drifted into a gentle sleep, his body still wrapped around you, you stared up at the darkening sky, your mind racing with thoughts of what you would do next. You loved him, and you knew he loved you. There was never any doubt of that.

But… just what kind of love was forged here tonight?
