I Took A Succubus's First Time

Yuuna had told Kouhei once that his power wasn't just special—it was something extraordinary.

"It has the ability to strengthen those you share a strong bond with," she explained, her tone serious yet tinged with admiration. "The stronger the bond you have with them, the more powerful they become. But it's not just that."

One night, after an intense session of sex, Yuuna brought it up again. Hina lay beside them, sound asleep after their usual threesome. Sharing the same bed like most nights, Yuuna decided it was the perfect moment to reveal what she thought was the truth behind his power.

"I think the power of the child of anti-prophecy is more complex than it seems, Kouhei-kun," she said softly, her fingers tracing idle patterns on his chest.

"What do you mean?" Kouhei asked.

"I'm not entirely sure yet," she admitted. "But every time we have sex, there's this rush of power surging through me—drastic, overwhelming. It feels like I'm overflowing with something I can't even contain."

"Really?" Kouhei tilted his head, trying to process her words.

"It's hard to explain, but during sex, there's a point where I feel this incredible power flowing into me, something I can't fully understand yet. Like... like I'm being supercharged."

Yuuna was convinced there was more to his power than they had seen so far. While they hadn't explored its full potential yet, the possibility loomed that his power wasn't just about strengthening bonds but also strengthening through sex itself.

"You said there's a point in time during sex when you feel this?" Kouhei asked, his brow furrowed. "When exactly does it happen?"

"When we both orgasm," came a sudden voice. Instead of Yuuna answering, Hina, who had been lying still with her eyes closed, chimed in. Apparently, she'd been awake the whole time.

"That's exactly it," Yuuna agreed, glancing at Hina with a knowing smile. "When both of us climax together, it's like something explodes inside me. It's an overwhelming power, something I've never felt before."

"Kouhei really is special," Hina murmured, scooting closer to him and snuggling against his side. "He makes us feel special too. The energy he sends to both of us—it's proof of that. When our hearts align, that's the strongest bond possible. And for that to happen, we need to aim for the same goal. That goal is reaching climax together."

Hina's reasoning was… unconventional, but it strangely made sense in the context of what they'd experienced.

"If there's ever a time you're in danger, or someone close to you is," Hina continued, her voice turning serious, "don't hesitate. Have sex with them. Make sure you both climax at the same time. When she cums, I'm certain you'll gain enough power to protect yourself and win."

"She's right, Kouhei-kun," Yuuna said, her expression soft but firm. "For our sakes, do whatever it takes to survive."

***

Kouhei reached out, his hands trembling slightly as they hovered over Nagisa's breasts.

"I'm sorry, Nagisa-san," he muttered, his voice low and tinged with guilt as his palms finally cupped her soft flesh.

Hina's words echoed in his mind: The strongest bonds are formed when hearts align. And to do that… have sex with her.

But how was he supposed to align their hearts in a situation like this? Nagisa was barely conscious, her head lolling to the side from the devastating punch she'd taken earlier. Her breathing was shallow and her strength all but gone.

"U...unn..."

Nagisa let out a faint groan, but her consciousness still hadn't fully returned.

"Why the hell am I even doing this…?" Kouhei muttered to himself, his voice low and conflicted. Yet, he knew if he stopped now, they'd both be dead.

"Come out of there, you bastard!" Takahashi's enraged scream echoed from outside the barrier Kouhei had erected.

The barrier, a lifesaving measure Yuuna had created for him, was holding Takahashi off for now. But it wouldn't last forever. Its strength depended on the enemy's power, and Takahashi wasn't weak. Kouhei estimated it might hold for about an hour at most—maybe less if Takahashi kept hammering at it.

He had to act fast. He needed to wake Nagisa, and he needed her awake enough to… well, do it. It wasn't a plan he was proud of, but it was the only thing he could think of in this desperate moment.

"If I remember correctly," Kouhei thought aloud, "touching someone's erogenous zones can wake them up. I don't know if that's true, but…"

He swallowed hard, his heart pounding. Erogenous zones were sensitive areas on the body, places that could react even in sleep. He had no idea if it would work, but he had to try.

Sliding his fingertips from her shoulder down to her arm, he carefully watched Nagisa's reaction. Her uniform, torn from the earlier fight, revealed patches of bare skin. The damage had left holes in the fabric, and her bra was partially shredded, exposing just enough of her breasts to make Kouhei's throat tighten. The softness of her arm was like silk beneath his hand, and for a moment, he was lost in the sensation.

"Uuun…"

Nagisa let out a faint noise, her face twitching slightly, but she still didn't wake up.

Kouhei pressed on, methodically exploring other areas. His hands skimmed along her armpit, her side, her waist, then her thigh and calf. Everywhere he touched, her body was impossibly soft, almost unreal—like pressing into a luxurious mattress. Despite his efforts, though, Nagisa's reactions were minimal, and she still showed no signs of waking up.

"Then…"

Kouhei's eyes drifted downward, and he couldn't help but gulp. If the subtle touches weren't enough, he'd have to try somewhere more… sensitive. His hands hesitated before carefully parting her legs, his palms resting on the smooth skin of her inner thighs.

Before he realized it, he was completely absorbed by the feeling of her body beneath his hands.

"Aaa… n… haaa…"

Nagisa's cheeks flushed a deep red, her lips parting slightly as soft breaths escaped.

Kouhei found himself kneeling between her parted legs, his hands gripping the supple flesh of her thighs. A faint, floral aroma wafted toward him, delicate yet intoxicating. It was the distinct scent of a woman—one he recognized from being with Yuuna and Hina before.

His gaze drifted upward, and he was struck by the sight of Nagisa's blushing face. Her beauty in this moment was almost hypnotic, her sweat-dampened hair clinging to the nape of her neck. His eyes traveled lower, following the rise and fall of her chest as her breathing grew heavier.

Her breasts, barely restrained by the tattered remains of her bra, moved enticingly with each breath. The fabric of her uniform strained against the hardened tips of her nipples, pushing upward as if defying the constraints.

Kouhei forced all his strength into the muscles of his neck, tearing his gaze away from Nagisa's alluring breasts. His eyes dropped lower, down to her exposed navel. Her shredded uniform left her stomach bare, the smooth skin teasing him with its vulnerability. Desperate, he lowered his head and licked the center of her stomach, his tongue trailing over the curve of her navel.

"Haaaan… haaa…"

Her soft moan barely escaped her lips, her reaction minimal.

"I guess I have no choice but to go lower…" he muttered, his voice tinged with both desperation and determination. His gaze traveled further down, past her navel, to the area between her thighs—the dangerous triangle where the body met the legs. Kouhei hesitated for a moment, his heart pounding wildly in his chest. This wasn't unfamiliar territory for him, but for Nagisa, it was her first time. He had no time to dwell on that, though. He needed to rouse her, to save them both.

Lifting her skirt, his eyes fell on her panties—a seductive red pair with delicate strings hugging her hips. The fabric clung to her in the most sinful way, emphasizing the soft valley formed by shadow and highlight. It was maddeningly enticing.

His head grew dizzy from the sheer charm of her body, his pulse thundering in his ears. His desire surged, a relentless ache that threatened to consume him entirely. It felt like his body was on the verge of exploding.

"I won't let us die, Nagisa-san," Kouhei declared, his voice filled with conviction. "I want you to become my woman!"

The words spilled from him, unrestrained and raw. His desire for her was undeniable now. He realized he loved her—the way she teased him, flirted with him at every chance, and openly professed her feelings. How could he not? His love for her matched the intensity he felt for Yuuna and Hina. He refused to favor one over the other, and they loved him all the more for it.

Suddenly, as if responding to his emotions, a radiant red light flared in his eyes.

Nagisa's body twitched, a pained yet delicate sound slipping from her lips. She twisted slightly, her movements as though she could feel the weight of his gaze on her. Red particles began to scatter from her body, shimmering in the dim light. At that moment, Kouhei felt it—their hearts were aligning.

"Uu… n…"

Nagisa's eyes fluttered open, her expression hazy and entranced. Her defenselessness only made her look more irresistibly lovely, and the sight of her like this broke whatever restraint Kouhei had left.

His hand reached for her magnificent, soft breasts, pulling them free from the torn remnants of her uniform and bra. He stared at them, captivated.

It was as if he were gazing upon a masterpiece crafted by the gods. Her pale skin was kissed by a subtle tan at the edges, and at the peaks of the soft mounds, her pink nipples stood proudly. Kouhei's hands claimed those summits, squeezing them gently, savoring the warmth and softness.

Driven by a primal need, he lowered himself between her thighs. His face hovered over her red panties. Without hesitation, he dove in, pressing his mouth to her covered petals and licking through the material.
