Chapter 321 (Se-young, Su-a)
There was a bit of a line for the ladies' room, but fortunately, it wasn't too crowded.
After confirming that his sisters were in line, Si-woo walked toward the entrance of the men's room.
Keeping a bit of distance from them, Si-woo pulled up the vibrator control app on his smartphone screen.
The app displayed the vibrator's status along with the control buttons. The battery was low, with only about 20 percent remaining.
It wasn't much, but it seemed like more than enough to throw Su-a into a panic.
In front of and behind Su-a, female students around Se-hee Noona's age were lined up, their eyes glued to their smartphones.
Si-woo imagined how flustered Su-a would be, caught among all those people, if he suddenly activated the device without warning.
As if to drain the last bit of energy, Si-woo pressed the activation button.
Su-a’s body jolted as if startled, coinciding with the vibration of his smartphone.
For a split second, her eyes met Si-woo’s.
Su-a looked at him with a troubled, pleading expression.
Ignoring her silent plea, Si-woo cranked the vibrator's intensity to the maximum and activated the hold button.
Not knowing what to do, Su-a hunched her shoulders and shrank inward.
Se-young, who had been watching from beside her, looked back and forth between Su-a and Si-woo, a playful "I can't help you" expression on her face.
Then, Se-young reached out and turned on the portable mini fan hanging around Su-a’s neck.
A tingling sensation of impending ejaculation surged through Si-woo’s cock.
After watching his sisters for a moment longer, Si-woo stepped inside the men's room.
* * *
Si-woo sat inside a toilet stall.
On his vibrating smartphone, he looked at the photo of Su-a he had posted earlier in the group chat with Mom, Aunt Seon-ju, and Se-hee Noona.
It was the voyeuristic photo he had taken on the train to check the color of Su-a’s panties.
Currently, Su-a was wearing both the vibrator and a panty liner.
Aunt Seon-ju had made her wear the panty liner in advance to prevent any virgin blood from staining her clothes during her first time with Si-woo.
Thanks to that, even though she had been tormented all morning by the vibrator Si-woo and Se-young kept triggering, Su-a hadn't completely soaked her legs with pussy fluid.
—Though it looks like enough fluid is leaking between her thighs for me to notice...—
Just how much was she leaking right now?
The girls had to stand among the crowd for quite a while to wait their turn.
The vibrator's battery dropped to 5 percent.
Si-woo’s heart began to race again as he imagined the shame and masochistic excitement Su-a must be feeling.
Inside Su-a’s bag, her smartphone, cards, panties, and panty liner were all tucked away, soaked in Si-woo’s semen.
Si-woo had ordered her not to wipe anything down except for the smartphone she needed to use.
The rest of the items were to be kept in the bag, defiled by his semen.
Until they returned home, Su-a would be walking around the department store all day with his ejaculated semen inside her bag.
Sitting on the toilet, Si-woo lowered his pants and underwear, pulling out his erect cock.
His massive cock, swollen and rigid with veins bulging, sprang out from his clothes as if a seal had been broken.
Using his vibrating smartphone camera, Si-woo began taking photos of his cock.
Click! Click! Click!
He captured his thick, imposing cock from various angles.
Si-woo sent the photos of his cock to Se-young via text.
He had a history of exchanging obscene videos and photos with Se-young several times already.
However, the maddening tension and transgressive thrill he felt before the number next to the photo disappeared never seemed to get easier to handle.
Before long, the number next to the photo in the chat window vanished.
Se-young had checked the photo of his cock.
Even after seeing the explicit photo of his genitals, Se-young didn't reply immediately.
Was she flustered, seeing a photo of her brother’s cock on her phone while surrounded by people in a public place?
Her reaction wasn't much different from before, but Si-woo’s excitement peaked as he imagined the embarrassment she must be feeling.
'Are you still in line? How much longer do you think it'll take to get into the stall?'
Si-woo sent a question to check on Se-young’s state after seeing the photo.
After a deliberate pause, Se-young’s reply arrived.
'We just got in~ with Su-a! Are you in the bathroom too, Oppa?'
Se-young responded in her usual tone, as if she didn't care much about the photo of his cock.
Si-woo felt a sense of relief that she acted as if nothing had happened, yet he also felt a strange sense of indignation.
He wrapped one hand around his massive shaft and began to stroke it up and down.
A current of pleasure, hot enough to melt his sensitive skin, seemed to vibrate through the entire length of his cock.
He picked up his vibrating smartphone and took more photos of his massive cock as it moved.
Click! Click! Click!
Several photos of his hand moving up and down and his swaying cock were saved to his phone.
Instead of answering Se-young’s question, Si-woo sent her the photos of himself masturbating.
The images of him stroking his cock appeared in the chat window.
The number next to the photos disappeared the moment they were uploaded.
Si-woo had already tried to show Se-young his masturbation earlier that morning by exposing himself.
Now, his relationships with Mom, Se-hee Noona, and even Aunt Seon-ju had been exposed.
He had even received a handjob from Su-a on the subway and ejaculated into her bag.
On top of that, he currently had Su-a’s vibrator turned on.
At this point, even if they exchanged high-level obscene photos or dirty talk, he wouldn't be misunderstood or viewed as a creep by Se-young.
However, regardless of the physical affection and obscene acts that were actually being permitted, Si-woo still wasn't sure how to understand or define his relationship with Se-young.
He couldn't even pinpoint exactly what kind of bond they shared now.
Driven by impulse, a part of him wanted to tear down all boundaries and pursue limitless, unrestrained pleasure, while another part wanted to continue this game of lewd relations within a precarious balance.
How long did Se-young intend to keep their secrets hidden while maintaining their everyday relationship like this?
Did she think he had broken the unspoken rules they had kept between them by sending those masturbation photos in succession?
Feeling as if he were exploring uncharted territory, Si-woo waited for her reaction after sending the obscene photos.
'Wait just a second~!'
A text from Se-young reached Si-woo as he stared intensely at his screen.
Until now, they had shared fragments of each other's secrets, but it had never led to specific questions or long conversations.
Si-woo thought that, for the first time, he might be able to carry on a lewd and decadent text conversation with Se-young.
His heart raced wildly for a while after receiving her reply to his masturbation photos.
Soon, a video arrived from Se-young.
It was a video showing the inside of Su-a’s bag, held open wide.
The hum of the fan motor and the vibration of the device could be heard.
Faintly, Su-a’s leaking moans were mixed in as well.
The filming seemed to be taking place inside a toilet stall in the ladies' room.
Su-a was holding the bag open with both hands, revealing the interior to the camera.
The items inside Su-a’s crossbody bag were a mess, covered in Si-woo’s semen.
Not only Su-a’s smartphone, but her debit card, panty liner, and wine-colored panties were all drenched in his semen.
Se-young, holding the camera, reached out with her other hand and rummaged through the items one by one.
The semen coating the objects smeared between Se-young’s fingers.
Se-young pulled Su-a’s smartphone out of the bag and pressed it into Su-a’s hand.
Su-a took the smartphone, which was stained with Si-woo’s semen like a blotch, from Se-young.
Su-a began to wipe the phone down with the wet wipes Si-woo had bought her.
For a moment, the sound of Se-young’s giggling could be heard in the video.
