I Took A Succubus's First Time

"K-Kiyohara-san..." Kouhei's voice came out in a breathy whisper, still reeling from the sensation. That kiss—it was unlike anything he'd ever experienced. It wasn't just a kiss; it felt like she was trying to drain his very essence, like she wanted to pull the breath right out of his lungs.

"You really are wonderful..." Nagisa's voice was a sultry purr as she gazed down at him, her eyes glittering with a mix of satisfaction and desire. Kouhei's cheeks flushed, his heart pounding from the intensity of it all. Then, with a sudden burst of energy, Nagisa pushed him down onto the bed.

In the blink of an eye, Kouhei was on his back, sprawled out across the mattress. Nagisa wasted no time—she climbed onto him, straddling his waist, her warmth pressing into him through the thin fabric of her lingerie.

"I didn't want to skip any steps, but I just want you so much, Kou-kun..." she whispered, a wicked smile curling her lips. Her fingers slid under the straps of her negligee, pulling it slowly down her shoulders. The silky fabric slipped away, sliding down the curves of her body until it pooled on the bed beneath them, revealing her bare skin to his stunned gaze.

Kouhei swallowed hard, his throat dry, his breath hitching as he took in the sight before him. Her body was flawless, each curve highlighted by the moonlight spilling through the window. There wasn't an ounce of excess on her figure, and her breasts—round, full, and heavy—rivaled even those of the President and Hina.

"Do you want to touch them? You're free to, you know?" she teased, her voice dripping with mischief as she leaned closer, her lips brushing against his ear.

Kouhei swallowed again, a deep, instinctual need rising within him. Without thinking, his hands moved, reaching up to grab her breasts over the thin material of her bra. His fingers dug into the soft flesh, feeling the warmth and the weight in his palms.

"HannnNnng~"

Nagisa shivered, a moan escaping her lips as his rough touch sent shivers racing through her body. It felt like electricity was shooting from his hands, sparking through her nerves and lighting up her skin.

"I never knew you were so bold, Kou-kun," she murmured, a seductive smile spreading across her face.

I never knew either… Kouhei thought, his mind spinning. It felt like something raw and wild was stirring inside him, drawn out by the girls in the Sarushima mansion. It was like the longer he stayed here, the more his instincts took over, pushing him to act on desires he barely understood. But right now, all those thoughts melted away under the weight of her breasts in his hands. He could only focus on the softness against his palms, the way his fingers pressed into her skin. He squeezed them gently, his hands moving in slow circles—one clockwise, the other counterclockwise.

"You can grab them directly, you know?"

I can do what? The words echoed in his head, catching him off guard. He blinked up at her, trying to process what she'd just said.

"Here," Nagisa said with a smirk, her fingers sliding to the center of her bra. She pinched the fabric where it met between her cleavage, pulling it up and letting her breasts spill out.

Kouhei watched, mesmerized, as her breasts bounced free, jiggling slightly before they settled back into place. The sight of them—full, round, with nipples standing stiff and hard—left him breathless. Her areolae were a soft pink, like sakura petals, the perfect contrast to her pale skin.

"You can touch them like this," she whispered.

Kouhei's throat tightened, and he felt another gulp rise up as he stared at the sight before him. His hands moved toward her bare chest, but just as his fingers were about to brush against her warm skin—

BAM!

The door flew open, slamming against the wall with a crash that shook the room.

"Nagisa-san! What are you doing?!" A voice rang out, sharp and furious. Kouhei's head whipped around to see Touyama Kozue standing in the doorway, her eyes blazing with anger, her teeth clenched tight like a guard dog that had caught another stealing its prey.

"What do you think?" Nagisa replied coolly, a sly, unrepentant smile playing on her lips. "I'm forming a bond with Kou-kun!"

"And here I thought the President was the only one I had to worry about..." Kozue muttered, her voice dripping with frustration. She cast a quick glance toward Kouhei, then snapped her gaze back to Nagisa. "But this is no time for this. There's a situation outside."

"Situation?" Nagisa's brow arched, her expression shifting from playful to serious.

"Demon hunters. They've tracked us down—they know we're hiding here," Kozue said.

Kouhei's blood ran cold at the mention of the demon hunters. He knew what they were after—him, and they wouldn't hesitate to kill. 

"Looks like we have a situation indeed," Nagisa said, her playful demeanor vanishing as her face grew tense, her eyes sharpening with focus.

She slid off Kouhei's waist, her warmth leaving him as she grabbed her discarded negligee. She moved with a purpose, her bare feet making soft thuds on the wooden floor as she headed for the door.

"I-I'm coming too!" Kouhei blurted, stumbling forward.

"You stay here, Kou-kun. They're after you," Nagisa's tone was firm, almost scolding. "I don't want you throwing yourself into danger."

"I don't want you fighting for me either!" 

Nagisa turned, her gaze piercing into his. "And what exactly can you do, besides seducing us?"

"S-Seducing?" Kouhei stammered.

"You've seduced Hina-chan, the President, and now Nagisa-san too," Kozue interjected, stepping forward with a bitter glare. "You can't do anything else, can you? If you show up, you'll just be a burden and put yourself in danger. You're the one who's supposed to help us win against the Heavens, remember? So, if you think you're going to fight, you're just making things worse for all of us. Now, stay put. Nagisa-san, let's go."

Nagisa sighed but nodded, casting Kouhei a softer glance. "Sorry, Kou-kun, but here—" She suddenly rushed back, catching him off guard. "You can have this to remember me by, for now."

Before he could react, she seized his hand, pressing it firmly against her bare breast. The warmth and softness filled his palm. Her skin was smooth, and the heat of her body left a searing imprint on his senses.

Then, just as quickly, she pulled away, leaving him standing in stunned silence. Her bare feet padded against the floor as she hurried out, the door clicking shut behind her.

Kouhei stood frozen, staring down at his hand as it twitched with the phantom sensation. He flexed his fingers, trying to hold onto the lingering warmth, the softness that still buzzed in his nerves.

"It's... soft," he whispered to himself.
