Chapter 102: Masturbation in the Car [R-18]

Seojin stood before the car, breathing in the damp air of the underground garage.

Rio had opened the passenger-side door for her, but now he stood before it, arms crossed, looking down at her.

“You can only get in the car wearing that outfit from before.”

“…You want me to take my clothes off, here and now?”

Rio simply nodded. His expression was blank, but his gaze alone told her he wasn’t joking.

“Start with the T-shirt.”

Seojin instinctively glanced around.

She had thrown her street clothes on over the swimsuit—a garment that did absolutely nothing to conceal a person’s body—just to get here.

They were in a corner of the parking garage, so thankfully, the area was deserted. Still, it was a quiet, enclosed space where someone could pass by at any moment.

Even though they were next to a pillar, it was clear that if someone did walk by, Rio’s body, blocking the car, would offer her no protection. If someone looked through the gap, they could see everything.

“……”

Nevertheless, Seojin gripped the hem of her T-shirt and cautiously pulled it upward. As the fabric lifted, the contours of the mesh swimsuit, stretched taut against her skin, were revealed.

Her nipples already strained against the tight netting, pushing through the gaps, and the black string did nothing to cover them, simply hovering in the air.

Rio tilted his head down slightly, his eyes tracing her form. He remained silent.

Next was the skirt.

She placed her hands on her waist, slowly unzipped it, and stood perfectly still as it slid past her hips and fell to the floor.

Rio’s gaze swept slowly over her legs, her hips, her stomach. The mesh swimsuit cut into the curve of her ass, clinging so tightly it looked as if it had been carved into her skin.

She trembled, glaring up at him as if to ask if he was satisfied. Only then did he nod.

“Please, get in, my princess.”

As if he were a different person from the man who had just blocked her path, Rio escorted Seojin with the utmost chivalry.

Clutching her clothes, Seojin covered her chest with both hands and climbed into the car he had made way for. The moment the passenger door slowly clicked shut, she had entered a space that was Rio’s alone, hidden from all other eyes.

He walked around to the driver’s side as if nothing had happened.

The sound of the car door closing echoed softly.

In the silence of the empty underground garage, the sound carried a sense of finality. Seojin sat in the passenger seat, her hands covering her chest, her body clad in nothing but that thin mesh.

Her nipples, already hard, pushed against the fabric between her clasped hands, creating small peaks in the netting. The flimsy mesh only veiled her form; it did nothing to hide the heat of her skin.

Rio got into the driver’s seat and fastened his seatbelt. He started the car nonchalantly and didn’t even glance toward the passenger seat as he drove up to ground level.

In the silence of a red light, the only sound was Rio tapping his fingers on the steering wheel.

Seojin held her breath, tense. She knew he wouldn’t make her sit next to him in this outfit and do nothing. As she kept stealing glances at him, Rio spoke without turning his head.

“Nervous?”

At his words, she instinctively squeezed her knees together.

“…No.”

Seojin’s reply was quiet. She stared straight ahead, avoiding his eyes, but her body trembled, and her voice sounded as if she had swallowed something.

Apparently pleased with her answer, Rio leaned an elbow on the steering wheel and slowly turned his head to look at her.

“Then…”

His voice was low and soft. And his next words were steeped in a context that only the two of them understood.

“You’re going to keep me entertained, just like yesterday, aren’t you?”

Rio was waiting for the Seojin who had worked so hard for him on top of him yesterday. His face held an utterly gentle smile, but the intention behind it was clear.

A demand, an expectation, or perhaps a playful declaration.

Seojin tried to avoid his eyes, but she was caught in his gaze, only managing to turn her head slightly.

All that covered her body was a thin net. His stare, passing through it, felt as tangible as a physical touch on her skin.

When she said nothing, Rio turned his gaze back to the steering wheel. The smile still playing on his lips meant his interest hadn’t faded.

“Put your fingers inside.”

The light changed and the car started moving. The only thing filling the car was Seojin’s anxiety as she used both hands to keep the seatbelt from pressing too hard against her nearly naked body.

“…Rio.”

“Yes.”

She called his name as if clinging to a rotten lifeline, but Rio had no intention of calming her down.

There was only one thing she could ask for.

“The windows… don’t roll them down…”

Shrinking with shame, Seojin clutched the T-shirt and skirt she had been wearing as if they were her only comfort. She parted her legs just enough for her hand to slip through.

Then, she squeezed her eyes shut and began to feel for a gap in the mesh, relying on touch alone. Once she found her entrance, it was surprisingly easy, slick with wetness.

“…Ah…”

Her fingers slid between her damp folds. She instinctively sucked in a breath.

“How many fingers?” Rio asked as she began to touch herself, the corners of his eyes crinkling with amusement.

“…T-two…”

“You need to fit one more,” he said casually. His hands were still on the steering wheel, but with a single phrase, he made her tremble from the inside out.

She exhaled a thin breath and slowly moved her fingers, though she couldn’t manage to add another one just yet.

Her trembling fingers pushed deeper and deeper. She twisted her hips subtly, burying her palm between her thighs.

As her fingers stirred her wet flesh, a tingling sensation shot through her.

“Heuk…!”

When the smoothly moving car stopped at a red light, Rio turned his head to watch her openly. He observed her movements without a word.

Seojin felt her breath catch under his gaze.

“Open your mouth.”

When he spoke in a low voice, Seojin instinctively parted her lips. In that instant, his hand reached across to the passenger seat and ravaged her mouth.

After a brief exploration, he gripped the nape of her neck lightly before his hand returned to the steering wheel.

“Fucking hot…”

Masturbating next to a man while he drove was an incredibly shameful act.

The passing scenery and the bright sun hit her head-on, but instead of the refreshing feeling of a drive, all she felt was the obscene guilt of fucking her own pussy.

At the next red light, he unbuckled his seatbelt for a moment, leaned closer, and abruptly pushed her seat all the way back.

Seojin thought he was going to kiss or hug her, but the sudden movement only made her body jolt, sending a powerful wave of stimulation through her.

“Rio, ah, Rio…!”

Taking advantage of the reclined position, Seojin propped one leg up on the seat, settling more firmly into her spread-eagled position.

Now that her line of sight was away from the window, she grew bolder.

“Yes.”

Watching her churn her fingers inside her pussy while calling his name, Rio suddenly grabbed her hand firmly.

And then he began to move it for her, shaking it roughly.

“Ah, ahhng…! Heut…!”

Her hand was pushed in and out between her legs, and a wet, squelching sound slowly began to fill the car.

The mesh between her legs was already soaked with her wetness, and her flesh bulged against the tight netting. With every movement, the mesh scraped against her sensitive skin, a stinging sensation that was even more stimulating than the entry of her fingers.

Seojin whimpered, looking at Rio.

“Rio, ahhh—! Stop, no!”

Rio laughed. His satisfaction with her aroused state was unconcealed, nor did he need to hide it.

Wet, squelching sounds filled the car instead of jazz.

“Oh, really?”

It was just a petulant complaint, Seojin’s desperate struggle against the shame of coming. But before she could reach her peak, her voice thick with nasal moans, his hand moved upward.

If you say no, I guess I have to stop. He moved his hand to her chest and roughly grabbed one of her breasts, still bound by the mesh.

Her nipple, already straining through the tight netting, met his touch, and Rio twisted it, grinding it down.

“Ugh…! Hah…!”

Just as she was about to come, the pressure he was applying vanished. Now, she had to move her own fingers below while her breasts were manhandled by his hand above.

Her nipple slipped out of the mesh and back in, sliding against his palm. She turned her head, gripping the seat and panting for breath.

“…Ri, o…”

As she whimpered again, begging for his help, Rio spoke calmly.

“Keep going. You can do it by yourself.”

In the space his hand had left, Seojin began to fill herself once more. The stimulation wasn’t enough to match the sensation his hand had accustomed her to, so she had to move deeper and faster.

The wet mesh slapped against the back of her hand as more fluid dripped from within.

A car honked from behind, forcing Rio to let go of her breast, sit up straight, and drive. But his mind was entirely on her.

For Seojin, his help was now truly impossible, no matter what.

“Hah… haah… ahh…”

Seojin pushed herself, feeling Rio’s gaze on her. His eyes would look at the road, then drift to the rearview mirror, silently tracking her as she writhed, her body shaking violently.

“Ugh…!”

Rio let out a low laugh.

At the end of a fierce, debased battle with pleasure, Seojin’s lips trembled as she clenched her core. Her head kept hitting the headrest as her body thrashed, shaking as it was consumed by pleasure.

She paused for a moment, exhausted. Then, in a daze, she did as he had told her and added another finger, moving her hand once more.

“Ugh, uuuh, haah—!!”

She finally succumbed, coming apart under his watchful gaze.
