Miku knocked on the door a few times, then quickly moved behind Mitsushima and shoved her inside the moment the door opened.
Even before Mitsushima could steady herself and glance back at Miku to complain about being pushed, someone tightly grabbed her hands and pulled her deeper into the dimly lit room.
"Wait! What are you—"
Miku closed the door, completely trapping Mitsushima inside the storage room with Nach, Saeko, and, unknown to her, Takashi.
"Why did you do that, Yuuki-san?" Yui complained, worried about what she was sure would happen between Nach and Mitsushima.
"Because Nach-sama deserves to have all the women he desires," Miku proudly said, full of devotion and without any hint of doubt as she leered at Yui to tease her.
"Are you expecting to be next, perhaps, Yui?"
"At least call me Hashimoto-san since I'm older than you! And how can I do it with Nach in this kind of dangerous situation?!"
"Then you won't go next after?"
"Ehh?"
While Yui weighed her choice between her growing lustful desire and her reason and judgment, the intimacy inside the storage room continued.

Seeing Nach completely naked—his muscular frame and massive erection exposed right before her—Mitsushima finally realized he wasn't just a handsome pervert, but a savage beast who would never let his prey escape.
And that prey was her.
"Wait! What are you—"
Mitsushima tried to reason with Nach, but he aggressively sealed her lips with a kiss.
She tried to push him away, but he held her in an embrace so tight. His arms wrapped around her waist, pressing his massive hard erection against her belly, lifting her up so that her feet left the floor.
He carried her and laid her down on the floor—atop the gym mats—where she saw Saeko sleeping soundly, completely naked.
Her attention shifted back to him as he straddled her, restraining her hands by the wrists, and kissed her again.
She tried to resist, but despite his aggressive kissing, she couldn't deny that it felt incredibly good.
It didn't take long before she began responding to the kiss, opening her lips on her own and inviting his tongue with hers inside her mouth.
And it wasn't only the kiss that was making her lose her reason and judgment.
The masculine scent filling the entire room clouded her mind each time she took a deep breath.
The burning heat from his body penetrating through her clothes made her body heat up as well.
And the intense throbbing of his rod pressing against her crotch made her body twitch in anticipation, her entrance soaking wet in preparation to take him in, her legs spreading on their own to invite—or rather, beg—for him to penetrate her.
"Ahh~!"
Moans began to escape her lips despite their ongoing aggressive kiss as she felt his rod rubbing against her entrance.
Nach couldn't penetrate with her panties still on—or so Mitsushima thought.
To her surprise, his rod skillfully slipped past her lace panties and found her entrance.
"AHH~!"
She couldn't help but break their kiss and moan loudly the instant he penetrated her entirely, the tip of his rod kissing her womb.
The sexual pleasure and stimulation of the penetration, along with the pain—as if she had lost her virginity again due to how big he was—and the new sensation of something reaching her womb brought Mitsushima into an intense orgasm she had never experienced before.
Her body trembled as she continued to moan. But despite her ongoing orgasm, he began to move again.
He pulled back and thrust in again, this time much deeper as his rod pushed her womb back.
"AHH~!"
Her second orgasm made her mind go blank and her vision turn white.
Regardless, Mitsushima remained conscious enough to feel the sexual pleasure and stimulation as Nach continued to pound her relentlessly, until he filled her womb with his thick, warm release, which finally made her faint.

"Who could have done this?"
Of course, Nach was only making fun of the situation.
With his still-erect rod inside Mitsushima, who was now sleeping soundly beside Saeko, it was obvious that he was the one who did it.
However, it was true that he was wondering what had actually happened.
He remembered doing it with Saeko, but he couldn't recall taking off her clothes, leaving only her thigh-high leggings.
It was the same for Mitsushima.
Nach had recollection of doing it with someone else, despite acting on pure instinct. At the time, he thought it was Miku or Yui who knocked on the door, which was why he didn't bother to stop.
His awareness only returned right after he climaxed inside Mitsushima.
He would need to apologize to Mitsushima later—not exactly for doing it with her, but for having done so without being fully aware of the situation.
Regardless of the fact that he now felt satisfied, Nach wouldn't mind having more.
He pulled out of Mitsushima and laid her down properly before standing up and walking toward the door.
"Huh?" Nach gasped, stopping midway as he was about to open the door when he noticed Takashi tied up and gagged, lying on the floor behind a shelf.
"Well… this is awkward."
The fact that Nach was completely naked and still rock hard in front of Takashi, their eyes locked on each other.
Not to mention Takashi's pants, which were stained with what looked like pee mixed with cum.
And to make it worse, Takashi was squirming on the floor, confirming that he was climaxing at that moment.
"Ignore it. I see nothing—probably just a hallucination."
Unsure of what to say, Nach decided to look away from troublesome things.
On that note, he wasn't sure how much time they had before the next trouble—Saki, to be exact—arrived.
"But we probably have enough time for another round," Nach said as he opened the door, with Yui stumbling right into his embrace.
"Did I make you wait, Yui?"
"Who said I was waiting?"
Despite her retort, Yui was the one who locked the door, turning her back on Nach, silently asking him to take her from behind.
Which Nach gladly did—not only to pleasure Yui and himself, but to demonstrate how much more superior he was compared to the supposed protagonist of the story.
