.

I groped Baek Seona’s chest over her bra.

Having felt various kinds of breasts, I now felt like I could measure their size simply by the sensation on my palm as I touched them.

“Seona. You’re a D cup, right?”

“What, you didn’t know until now?”

“I guessed it right.”

Upon taking off the bra to confirm, I saw that it was 70D.

Seeing G cups and F cups like Serena and Ciel every day, a D might feel small, but it was not a size to be taken lightly.

I closely admired her well-shaped chest for a moment.

“Why are you only looking when I told you to touch?”

“Because it’s beautiful. First, you have to appreciate it with your eyes, then you know how to truly enjoy it by touching.”

“…… It’s small compared to Serena and Ciel.”

It seemed Baek Seona had also compared them in her heart.

Well, I couldn’t completely ignore that, considering I was having sex here and there.

I decided to boost her confidence.

“The important thing is not the size. It’s the balance.”

“How’s my balance?”

“100 points.”

At my answer, Baek Seona smiled contentedly and said,

“Heehee. Oppa, your penis is 10,000 points.”

“What? 100 points is the maximum score.”

“Still, I’ll give you 10,000 points.”

She said this and turned her head, blushing as if she were embarrassed.

Despite having so much sex in all kinds of positions, there seemed to be something left to be shy about.

And that was cute.

I bent my head and sucked Baek Seona’s nipples gently.

“Slurp…, Slurp, Suck….”

“Heeek…♡ You’re really like a frog. I told you to touch, why are you sucking?”

“Chomp… What, I can’t suck?”

“Doha oppa, do you want to have sex right now…?”

“Of course.”

“Heehee. Smooch♡”

Baek Seona gave me a light peck on the lips and then gently caressed my penis over my clothes as if soothing a child.

“I want to, too, but… weren’t we going to post some information on the community? That’s why I was waiting in my room.”

“Ah… right.”

“You wanted to have sex with me that much? Heeheehee.”

Swish- swish-

She embraced my face between her breasts and stroked my head.

The soft and warm touch of her breasts… One of the best things about being with Baek Seona was feeling this kind of comfort.

It was like the innocence of a 20-year-old freshman college couple cohabiting in a one-room apartment and having sex.

“…Alright. Let’s have sex while writing the post for the community. That won’t be a problem.”

“What? How is that possible?”

“What can’t we do? Seona, you write, and I’ll thrust.”

“…I can’t do anything else when I’m being thrust into by you…”

“I’ll thrust gently. Only once every 3 seconds.”

“It won’t work…”

I spoke as I removed my clothes one by one until I was completely naked.

I then took off Baek Seona’s black suit skirt and white panties.

Even though she protested, pretending she didn’t want to, she slightly lifted her hips to make it easier for my hands to undress her.

“Seona, what’s this on your panties?”

“…Why are you asking when you know? It’s my love juice….”

“Why are you so wet even though we haven’t done anything yet?”

I asked with a truly puzzled expression.

“Really… You’re so mischievous.”

Baek Seona bowed her head, then whispered in my ear:

“I leaked down there because I wanted Doha oppa’s penis. I can’t hold it anymore, so give me that delicious penis quickly…♡”

She looked at me, her face flushed as if asking if it was enough now.

“Pass.”

I lifted Baek Seona’s hips and thrust into her immediately.

Thrust-♡

“Heeeeeek…♡ This is the feeling…♡”

Her vagina was already well-prepared, so my slowly penetrating penis was able to settle deep inside.

The warm sensation of her vagina squeezing up and down my entire shaft.

Hmm, it was stable, as expected.

“Should we write a post on the community after just one pleasurable shot?”

“…If you can do it.”

“What’s this, trying to tempt me? Is once not enough?”

“You know you can’t hold back just once, oppa.”

“I can hold it.”

I grabbed Baek Seona’s hips with both hands and slowly lifted her up.

Then she also put strength in her legs, crouching in an M shape, and slowly stood up.

Thrusting-♡

“Heeeeeek…♡”

The flesh inside her vagina pushed out, holding the penis shaft as if begging it not to leave, and love juice dribbled down from below.

“Seona’s vagina is really lewd. Look at how it’s gripping my penis.”

I stood up, leaving only the tip inside her. Now, I’ll remove the pressure and sit down to insert it again.

Thrusting-♡

“Hak, hooooook…♡”

It was just a single thrust, but it was so strenuous that Baek Seona’s face was covered with beads of sweat.

“Heek…♡ It’s because Oppa’s penis is delicious. A 10,000-point penis.”

“Heh, heh. Saying that makes me even more excited.”

“Really? Doha Oppa’s penis is like a drug. Once you taste it, you can’t get enough. I want to eat it again and again.”

“You said you want to keep eating?”

“Ahuuuuuuk♡!”

I began to earnestly shake Baek Seona’s hips up and down.

Squeak-♡ Squeak-♡ Squeak-♡ Squeak-♡

“Heek…♡, hoo♡, hot♡, hauuuuk…♡!”

She matched the rhythm of my shaking, putting strength in her legs to move up and down.

Like the sex prodigy who had tried the woman-on-top position for the first time, she had now become quite skilled.

“Our Seona can move well on her own now?”

“Heek…♡, I’ve received oppa’s semen so many times…! Huu♡, it’s very easy.”

“Really? Then I’ll take my hands off your hips.”

I removed my hands and leaned back comfortably.

Then I took a position while lying diagonally on the bed, and Baek Seona grabbed my shoulders and crouched, moving her hips vigorously.

Squeak-♡ Squeak-♡ Squeak-♡ Squeak-♡

“Hoo…♡ You thought… I couldn’t do it…? Hooook…♡, huk♡, hok♡, huk♡”

This was paradise.

Right now, I’m delightfully enjoying Baek Seona’s body without touching her with a single finger, only my penis moving inside her.

I gazed up and down her body as if inspecting her.

Her face contorted in ecstasy, and she strained her legs to hold back pleasure.

Her jiggling D-cup breasts and eye-catching pink nipples.

Her vagina was evolving into a snug custom-fit case for my penis.

When she moved down, only the flesh-colored outer part was visible; as she went up, the pink inner folds were exposed.

Thrust-♡ Thrust-♡ Thrust-♡ Thrust-♡

Feeling my gaze, she became excited, and love juice started flowing.

“Hooooo…♡! Oppa… wh, when will you come?”

“Eh? Already tired?”

“It’s not that… hot♡, but I think I’ll climax soon…!”

Sure enough, her vaginal folds slightly spasmed, showing that her climax wasn’t far away.

“You can go whenever you feel like it.”

“I want to go together…!”

“Such a brat….”

I grabbed both of Baek Seona’s hands, which had been supporting her, on my shoulders and held them tightly.

“Then I’ll move as I please from now on?”

“Ye, yes…! Please use my vagina to your heart’s content…♡”

Sitting down, I began to shallowly thrust, putting strength into my hips.

For ordinary people, this might not have been a satisfying position to penetrate. Still, even in this stance, I was skilled enough to thrust with full power.

Thrust♡Thrust♡Thrust♡Thrust♡Thrust♡

“Heh…! Hut♡, hok♡, heuk♡, hot♡, haaak…♡!”

Baek Seona swayed and wobbled like a birch tree in a typhoon, her hands held tightly with mine, fixed in the air.

Like a birch tree, her vagina firmly held onto my penis, clenching it at its root.

“Op, Oppa! Hurry, hurry, and cum! Please!”

“Ugh….”

She really seemed to want to climax with me.

Baek Seona desperately held back her orgasm, urging me to ejaculate in her. It was as if she were in debt.

Thanks to her desperate effort, my sensation of ejaculation also reached its limit. I felt like it would be pleasant if I came right now.

Thrust♡Thrust♡Thrust♡Thrust♡Thrust♡

“I’m coming….!”

“Haaah—♡, kkuh…♡, heeuuh…♡, aaahhhhhhhhh—♡♡♡!!!”

Like a massage machine, Baek Seona’s lower body began to tremble at an incredible speed.

Fwoosh-♡ Fwoop-♡ Fwoofwoosh-♡

Whoosh- whoorush- whooroorush-!

Love juice squirted from her vagina like a water gun.

I also ejaculated pleasantly inside her womb. As always, it was a stable pleasure.

“Hoo…. Indeed, you’re my personal onahole. I feel good….”

“Heeheehee♡”

Baek Seona now accepted the word ‘onahole’ as a pleasant compliment.

With a face drenched in sweat and looking tired, she collapsed into my arms and said,

“Thank you, Doha oppa, for cumming with me.”

“…Why are you so concerned about cumming together? I’m enjoying it enough as well.”

“It feels good to be united like this… We can also enjoy the afterglow together.”

With that, Baek Seona began to suck on my nipple.

“Chuup…♡, chzz♡, chyop♡, chooop…♡”

I gently stroked her head as she did so.

“What will you do if my nipples grow because of you?”

“Pffft! …Then I’ll take responsibility. Marry me.”

“….”

“I have to make Doha oppa’s nipples grow by sucking them harder. Chuup♡ …Ah!”

I pulled Baek Seona’s head away, held her in my arms, and laid down on the bed.

After having sex, it was customary to lie down and rest for a while with the penis still inserted.

Then, when I couldn’t resist the moist, clinging sensation of her vaginal flesh anymore, the second round of sex would begin.

Snuggled in my arms, she hugged me tightly and whined softly.

“Why won’t you let me suck your nipples? Don’t you want to marry me?”

“…It just feels weird to have my nipples sucked.”

“You suck mine just fine.”

“They’re my onahole’s nipples, so I have to suck them.”

“….”

Suddenly, Baek Seona pinched my nipple.

“Ow, why are you doing this?”

“Come to think of it, the first time we had sex… you said you’d do me whenever you got turned on in the middle of the night, but why haven’t you ever come?”

“….”

Good lord. Did she remember all that?

“I even gave you the keys….”

She spoke as if she were truly disappointed.

I found the situation a bit funny and chuckled.

“Heh.”

“…What? What’s so funny?”

“You’re cute, so I laughed.”

“….”

Baek Seona hugged me even tighter without saying a word.

Her soft breasts pressed and flattened against me, and her hard nipples rubbed against me.

Feeling that touch, my penis twitched with arousal.

“Heuk…♡”

I laid Baek Seona down on her stomach with my penis still inside her, then climbed up onto her buttocks.

“W-wait a moment. You said only once, right?”

“….”

Chiruruk-♡

“Huuuuuk…♡!”

I pulled out my penis and stood up, then fetched the laptop from the desk and placed it in front of Baek Seona.

“Now, Seona, write a post for the community.”

As she tried to get up to write, I gently pressed down on her back with my hand to keep her from rising.

She then turned her head to look at me.

“Oppa…? You want me to write lying down?”

“Yes. You write, and I’ll keep going.”

As she lay prone, I inserted my penis into the alluring view of Baek Seona’s backside.

Chibuk-♡

“Haaaaauk…♡”

I intended to move only once every 3 seconds, as promised.

Chigeoeeok-♡ Chigeoeeok-♡

“Heuuuk…♡, Heup…♡”

Baek Seona didn’t even manage to turn on the laptop and was just lying there receiving my penis.

Chang- Chang-!

I slapped her buttocks, urging her on.

“What are you doing, Seona? Write quickly.”

“….”
