I Took A Succubus's First Time

Three members of the student council sat in the dimly lit student council office. The second-year representatives, Saonji Hina and Touyama Kozue, were positioned near the window, while the president, Sarushima Yuuna, leaned casually against the desk. Okumura Kouhei stood awkwardly to the side, feeling like he didn't belong. He was the only guy there, and unlike the others, he wasn't even a member of the council. Why am I even here? he thought. But it seemed like he was about to find out.

"First of all, I want to know something." Sarushima's voice sliced through the air, turning both Saonji's and Okumura's attention toward her. Her eyes found Okumura's, and he felt a jolt as her intense ruby gaze seemed to pierce right through him. It was like falling into a crimson whirlpool, his breath catching in his throat. "Have you two had sex?"

"Wha—"

Okumura's mind reeled. He had braced himself for questions about his connection with Saonji, but this... this was far more direct than anything he could've imagined. Why the hell is she asking that?!

"Yes, we have," Saonji responded with unwavering calm, like she was simply stating the weather.

Okumura's face flushed red, his head hanging low. A hot wave of embarrassment washed over him, making his skin prickle. Great. Now my sex life's out in the open.

"I see." Sarushima's lips curled into a slow, knowing smile, her eyes glinting with a playful, almost predatory light. "So, is Okumura-kun any good?"

"W-Why are you asking that, president?!" Okumura stammered, his voice cracking under the pressure. He felt like his head might explode from how hot his face had gotten.

"Oh, it's nothing," Sarushima said lightly, waving her hand dismissively. "I'm just curious, you know? As someone who's known Hina since birth, I like to stay informed. That includes knowing about her first time with someone."

It was the strangest, most outrageous rationale he'd ever heard.

"It was very good," Saonji said, her voice steady and sure, like she had nothing to hide.

"Oh? Even though it was his first time?" Sarushima asked, raising an eyebrow.

"To be honest, I'm starting to doubt it was really his first time," Saonji replied. "Considering he managed to make me feel good."

It felt like some twisted courtroom, the way they were openly discussing him, like he was on trial with no way to defend himself. Each word made his stomach twist tighter.

"Hmm..." Sarushima's gaze slid back to Okumura, the playful glint in her eyes now mingled with something more dangerous, a teasing, seductive edge that sent a shiver down his spine. "Looks like this might work after all…"

Okumura had no idea what she meant by that, but there was a feeling in his gut that she was planning something, and it probably involved him.

"Now, allow me to explain something. Have you ever heard of Ayin, Okumura-kun?"

"I haven't," Okumura managed, his voice barely steady.

He hadn't heard that name before, not even in any fantasy stories or myths.

"But you've heard of God, right?"

"Yeah, of course."

"Yesh, also referred to as The Creator or simply Existence, is known by many names throughout Creation. He is the originator and sovereign of all realms—Creation, Heaven, Valhalla, and humanity—and is revered as the Father of Angels. Due to the immense power held within His true Name, most beings in Creation refer to Him as God, while only the most ancient among them are privy to His true identity. Yet, there is a lesser-known truth—Yesh has a sister."

Okumura didn't. It was the first time he'd ever heard anything like this, so he shook his head.

"Her name is Ayin—known as the Great Evil Beast, the NOT-IS, and the Anti-God. Ayin is a Pre-Existential Primordial Deity, representing Antimatter, Darkness, Evil, Impurity, and Chaos. She stands as the antithesis to God, embodying everything He is not. While Yesh brought forth Angels, Ayin created Demons. Yesh is the architect of the Abrahamic Heaven, whereas Ayin is the originator of the Abrahamic Hell. Yesh is God, and Ayin is the Anti-God. They are two sides of the same coin: acceptance and denial, order and chaos, positive and negative, existence and nonexistence, law and disorder, light and darkness, love and hate, good and evil. Together, they form the essence of all that has ever existed, exists now, or will come to exist, as well as all that has never existed, does not exist, and will never exist."

It was the first time Okumura had ever encountered such mind-bending revelations, and it sent a shiver down his spine.

"These two pre-existing entities are fated to wage an epic war against each other, a cosmic clash that will culminate in the Final Conflict of Heaven and Earth. Right now, Heaven and Hell are locked in a tense stalemate. Neither side dares to make a move, bound by an ancient agreement that keeps the peace—at least for now. But lately, the angels have been increasingly aggressive, pushing boundaries and infiltrating demon-protected territories with human consent. It's only a matter of time before Heaven and Hell clash again, and I believe that will trigger the Final Conflict."

Okumura's mind spun with everything he was hearing. It felt like too much at once. Why am I even being told all this? There had to be a reason he was hearing something so far beyond the ordinary.

"At this point, Ayin is destined to fall, while Yesh is poised for victory, leading the Heavens to obliterate Hell entirely. But sensing this imminent defeat, Ayin dispatched her power to a child—one who would hold the key to Hell's survival. It may not be enough to tip the scales decisively, but it could serve as a critical advantage. Without this child's influence, Hell's annihilation is all but guaranteed."

Sarushima's gaze bore into Okumura, her eyes sharp and penetrating, as if she were peering straight into his soul. The seriousness of her tone wrapped around him like a vise, tightening with each word.

"Okumura-kun, even after you touched and had sex with a primordial succubus, you didn't die. That fact amplifies my suspicions."

His throat constricted, and he felt a cold sweat bead on his forehead. The air around him grew thick with tension, his heart pounding like a war drum. He had a sinking feeling about what was coming next.

"You are the child that Ayin bestowed her power upon."
