...How is it?

Maybe 20 minutes had passed.

My arm was going numb.

I'd been holding that pose for so long that the muscles from my shoulder to my elbow felt like they were burning.

On the monitor, as time went by, countless lines were taking shape.

Because Seo-ah Kang's hand was still moving non-stop, drawing away.

I gritted my teeth and endured it.

'Just a little more...'

Since time had passed, the erection had mostly subsided by now.

However, the front of my pants hadn't flattened out completely; it was still slightly bulging.

I couldn't even adjust my pants because I was in a situation where I couldn't move.

About 10 more minutes passed like that, and by the time I'd been holding the pose for about 30 minutes.

Thud.

Seo-ah Kang put down her pen.

"...The simple sketch is done."

Hearing the welcome news, I tried to quickly relax my pose and take a look at the drawing, but.

"W-wait!! I need to take a picture."

I was stopped.

At those words, I stopped my body from moving and stayed still, and a moment later, I heard the sound of a few photos being taken with a phone camera.

"...Can I relax my pose now?"

"Do whatever you want."

I asked, worried I might get scolded again, but fortunately, permission was granted.

As I relaxed the arm I'd been holding up for a whopping 30 minutes, it felt incredibly numb.

It felt like I wouldn't be able to use my arm for a while.

As I sat on the bed and quietly massaged my arm, Seo-ah Kang continued.

"I'll show you the result when I finish it later, so h-hurry up and get out."

"...Yeah, thanks."

Since I couldn't see the monitor screen well while holding the pose, I tried to get up and take a quick look at how the simple sketch turned out—

But she issued an eviction order while desperately covering the monitor screen, as if to say she couldn't show it before the result was finished.

I thought about asking when it would be finished, but it felt like I was rushing her, so I just quietly left Seo-ah Kang's room.

Click—

As soon as she heard the sound of Si-woo Kang leaving the room and closing the door, Seo-ah Kang jumped up from her chair.

Holding her breath, she checked the door once more, then grabbed her black dolphin shorts and panties and threw them off all at once.

As her already damp pussy touched the air, her body trembled slightly.

"Haa...♡"

It felt like the excitement she had suppressed to the max while being with Si-woo Kang was bursting out all at once.

Seo-ah Kang dragged her staggering body toward the bed.

The spot where Si-woo Kang had been sitting just a moment ago.

She collapsed onto that spot, buried her nose in it—

"Huaa...♡ Haa...♡"

She inhaled deeply the lingering scent of Si-woo Kang.

She rubbed her nose against the spot where Si-woo Kang's body heat still remained and sniffed it.

Although it didn't have as much of his scent as the underwear he'd been wearing all day.

Since it was the place where he had been sweating while holding his arm up for 30 minutes, Seo-ah Kang could be quite satisfied.

With her eyes closed, she recalled what happened just a moment ago.

First, the pose she had instructed just now.

It wasn't just some pose of lifting an object.

"Hnn...♡"

It was a pose where Si-woo Kang used her as if she were a masturbation toy.

She had demanded that pose while imagining Si-woo Kang lifting her up with both hands and thrusting into her from below.

For the sake of the fantasy she was about to draw.

Furthermore, because she was able to have quite sticky skinship while adjusting his pose, Seo-ah Kang's excitement had reached almost its peak.

Above all, when she spread his legs.

She gathered more courage and reached out to stroke the inside of his thighs, and there was an unexpected harvest.

'Oppa... actually got an e-erection for me...♡'

Si-woo Kang had gotten an erection from her touch.

She had even witnessed it right in front of her, and had even touched it over his clothes right before pulling her hand away.

It was hot.

It was hard.

Even though it was over his clothes, it felt like the heat and throbbing were clearly transmitted to her fingertips.

She wanted to continue masturbating right away, recalling that sensation.

But—

With superhuman patience, she pulled her hand away from her pussy and sat back down in the computer chair.

It ‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠was to show the drawing to Si-woo Kang quickly and add the memory of being praised to have an even more pleasant masturbation session.

If someone else had heard it, they would have refuted it as strange logic, but to Seo-ah Kang, who was convinced that Si-woo Kang would definitely praise her if she finished early, it didn't matter at all.

After transferring the photos taken ‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠with her phone to the computer, Seo-ah Kang continued her work.

Line art, coloring, shading.

After an hour of work, shorter than usual, which continued without a moment's rest.

On the monitor, a scene was displayed of Si-woo Kang holding a whiteboard that said "I love you."

Since she couldn't show the original intent of the pose, she had added the whiteboard and the text.

However, that wasn't the end.

"...Now, for the next version..."

The next version, which she wouldn't show anyone.

She could have shown the finished version to Si-woo Kang right now and drawn the next version later.

Seo-ah Kang, who intended to masturbate while looking at that next version, made a copy of the drawing.

Then, she started erasing Si-woo Kang's crotch area.

Since it was for the purpose of showing Si-woo Kang, she erased the pants part of the original, which she had made flat without a bulge.

A moment later, only the part where Si-woo Kang's dick would be was erased to a blank white.

When Seo-ah Kang opened a folder—

Videos and photos she had secretly taken while hiding in Si-woo Kang's closet popped up in abundance.

"Haa...♡!"

Seeing Si-woo Kang's dick displayed on the screen, the urge to masturbate arose again.

Even so, Seo-ah Kang suppressed her sexual desire again, held onto her mind that felt like it was about to slip away, and grabbed the pen again.

She started to draw in detail on the empty crotch area of Si-woo Kang, referring to his actual dick in the video.

Every time the pen slid over the pad, Seo-ah Kang's breathing became increasingly rough.

"...Like this, the veins...♡"

She ‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠drew the length, thickness, shape of the glans, and every single vein of the dick in the drawing as realistically as possible.

At the same time, her legs spread apart, and love juice was dripping onto the floor under the chair.

"Haa... Haa...♡"

Her head was dizzy.

Her mind, struggling to hold back masturbation, was almost reaching its limit.

Eventually, she finished the second version as well.

"...Finished."

Seo-ah Kang leaned back in her chair and let out a sigh.

She really couldn't hold it anymore.

Just as she was about to open the door, thinking she should run out and call Si-woo Kang—

"Ah, my pants..."

She barely realized she had almost forgotten to put her pants on because she was so out of it.

Seo-ah Kang, having put back on the still-damp dolphin shorts she had thrown by the bedside, finally opened the door and came out into the hallway.

Just as she was about to enter Si-woo Kang's room right across the hall, she felt someone's presence in the kitchen.

Realizing that it was time for dinner and that Si-woo Kang was preparing it, she turned her steps toward the kitchen.

Soon after, she was able to find Si-woo Kang in the kitchen.

"...I'm done drawing."

Her heart was beating like crazy because of the dopamine that felt like it was about to explode, but she spoke as calmly as possible.

Then Si-woo Kang turned his head from the kitchen and looked at her.

"Oh, already?!"

When he smiled brightly and said he would follow her right away, Seo-ah Kang's heart beat even faster.

Just seeing the smile directed at her made her chest feel like it was overflowing.

She took the lead instead of Si-woo Kang and headed back to her room.

'He'll... praise me, right?'

While walking down the hallway, Seo-ah Kang was looking forward to what kind of praise Si-woo Kang would give her.

Finally, reaching in front of her room—

Slam—!

She swung the door wide open and pointed with one hand to where the monitor was.

"Here, look."

Outwardly, she pretended it was nothing and turned her gaze elsewhere, pretending not to expect any praise in return.

But when she felt the presence of Si-woo Kang freezing up after seeing her drawing, she felt a sensation of her lower abdomen going numb again.
