Chapter 4: Unknown Girl
The bell signaling the end of the second period rang.
“Ngh… mmmph…”
Akane writhed in pleasure from the effects of the aphrodisiac.
Her erection hadn’t subsided, but she couldn’t touch herself either.
The shame of being exposed in an M-shaped spread further amplified her arousal.
(How long am I going to be stuck like this…?)
Being toyed with like this and actually feeling pleasure made it impossible to deny that she was a pervert.
She could never hold her head up as Suzu’s older sister again.
Akane thought of Suzu’s smiling face and cried.
(I’m sorry for being such a perverted big sister, Suzu…)
At that moment, the rooftop door opened.
Akane froze and held her breath.
Someone had come up to the rooftop—she could hear footsteps from one person.
Her heart pounded with invisible tension.
Since she was restrained behind the air conditioning equipment, she wasn’t easily visible—but depending on where the person stood and their angle, parts of her body could be seen.
The eye mask could easily fall off too, and identifying her would be simple.
If that happened, at worst, everyone in school would know about her shameful state.
(Don’t notice me… Hurry up and start the third period already!)
Whether her wish was granted or not, the bell signaling the start of third period rang.
For now, she had avoided danger.
Relief washed over her as Akane let out a sigh.
“Huh!?”
But her wish hadn’t been granted at all.
Even though the third period had started, a surprised voice—clearly a girl’s—came from behind her.
She must have been taken aback by Akane’s perverted pose and her fully erect penis.
In contrast, Akane couldn’t even see who it was or explain away this humiliating situation.
(It’s over…)
From now on, just walking through the school would earn her pointed fingers and whispers of being a pervert—maybe even spreading to the neighborhood too.
If that happened, even Suzu might look down on her every day.
Thinking that made tears well up again, soaking the inside of the eye mask.
What was the girl who was probably still silently watching thinking?
If there was any chance of sympathy, Akane desperately wanted to be un-tied right now.
However, the girl’s hands didn’t go for the ropes.
Instead, they went straight for Akane’s bra-covered breasts—ones that were large enough for her hands to barely cover—and began kneading them.
“Ngh… hnn…”
Caught off guard by this unexpected caress, Akane let out a sweet breath.
The girl cupped them from below, squeezed them together, and made them tremble—techniques far too skilled for a high school girl but more than enough to make Akane feel pleasure.
Maybe because they were both girls, she knew exactly where it felt good. Unlike Chihiro, she didn’t tease—she went straight for the attack.
If this kept up, Akane felt like she might climax.
(Ah! No! I’m going to cum!)
Suddenly, one of the hands kneading her breasts let go.
The other hand continued playing with her chest, keeping the pleasure going.
Vvvvvv
As soon as one hand let go, a buzzing sound—like that of a bee—filled the air near Akane’s ear, making her uneasy.
When the source of the sound brushed against her earlobe, she felt vibrations and intense stimulation.
“Ngh! Mmmph!”
Akane couldn’t help but let out a sound.
This must have been one of the “toys” Chihiro had mentioned leaving behind.
Whatever it was, it was far too stimulating for Akane.
Imagining what it would feel like pressed against her penis made both her penis and female genitalia grow slick with arousal.
The toy moved past her navel, left her body for a moment, then pressed firmly against the tip of her penis.
“Mmph! Nnn! Nnnnn!!”
It wasn’t like being stroked by hand—it was more violent and intense.
Akane tried to pull her hips away from the stimulation but couldn’t escape as it was pressed firmly against her.
Before she knew it, the sensation of impending ejaculation surged through her penis.
(I’m going to cum! I’m going to cum!)
Inside Akane’s mind, a battle raged between wanting to ejaculate and not wanting to.
But her body was purely seeking pleasure.
No matter what she thought, Akane had no choice but to be trampled by pleasure.
“Nnnnnnghhhh!!!”
Akane arched her back so hard it felt like she might break as she trembled violently.
Semen shot out forcefully from the tip of her penis, staining her face and body.
It must have splattered on the unseen girl in front of her too.
“Nn… hnn…”
After being edged since yesterday and finally being allowed to ejaculate just now, Akane’s face was a mess of ecstasy.
Her penis twitched faintly as if reluctant to let go of the lingering pleasure.
Akane wasn’t thinking about what would happen next—she was just relieved to have finally ejaculated. No, she was so overwhelmed by pleasure that she couldn’t even think about anything else.
But what was going on inside her mind was unknown—and irrelevant—to the girl in front of her.
Once again, the buzzing sound filled the air as the toy was pressed against the tip of Akane’s penis.
“Ngh! Nnn!!”
(Stop! I already came once!)
The stimulation on her already overstimulated penis was nothing but agony after her first climax.
Akane shook her head violently, trying to convey her distress, but the vibrations didn’t stop—instead, they rubbed along her frenulum, delivering even more relentless stimulation.
And then Akane remembered.
This wasn’t loving sex—it was nothing more than rape, where the perpetrator took pleasure at her expense.
The moment she realized this, something strange happened: her chest tightened with arousal, making her penis grow even harder.
(I’m being raped… yet I’m still getting turned on. I’m such a pervert.)
The second climax brought with it an incomparable wave of pleasure compared to the first.
Instead of thick semen, transparent fluid gushed out from her penis.
Akane fully realized she was an irredeemable pervert as she greedily indulged in pure pleasure.
There was no room left for thought.
Even after that, until the bell signaling the end of third period rang, Akane was made to climax over and over again by the girl whose face she couldn’t even see.
