Evil Organization’s Extra Mr. A

[14th Chapter [19]]

With Yubin’s permission, it took only 30 seconds from lying on the same bed to having sex. In the narrow space of a single bed, we pressed against each other tightly and immediately shared kisses, while my hands entered her pajamas, groping her plump breasts.

Yubin also put her hand in my pants, touching my erect penis, and eventually, the passion ignited, leading me to remove her pajama bottoms.

We enjoyed sex in the missionary position, looking at each other. Although I had bought four packs of condoms a few days ago, the burning desire made us not think about contraception and dive straight into sex. After two internal ejaculations, we were in this state now.

“Ah, Ah, Ah!”

Like a puppy, I grabbed Yubin’s waist as she lay face down on the bed and thrust my penis into her wet vagina without hesitation.

“Ah, Older Brother! Haah, Hee! Jo, Joo…!”

“Is that good?”

“Good, Ahh! Eeuu, Unnh! Ahhh!”

Yubin’s expression, captivated by pleasure, was beautiful. To give her even deeper pleasure, I touched various parts of her body that excited her.

I kneaded her large, swaying breasts, and when our lips almost touched, we shared saliva.

“If you wanted sex so badly, you should have said.”

“If you say that, Older Brother might think I’m a strange girl. Ah, Ah, Ahhh!”

I heard that many women feel unexpectedly negative emotions like pain or tension during their first sexual experience. Some men also have their fantasies shattered during their first time.

But for us, the sex before our relationship was officially established gave us great pleasure and stimulation. We realized this just moments ago, and at least I felt very good about my first time.

That day, due to a lack of opportunity to talk about the first time, we postponed the conversation until we had sex again recently. Yubin received stronger stimulation than I did, especially when I inserted and moved deeply inside her.

“You wouldn’t think that.”

Following Yubin’s wishes, I thrust my penis in as far as possible, and at the moment the glans met her cervix, Yubin moaned erotically.

Moaning stimulated the man, who then worked harder at the back-and-forth motion.

These two actions intertwined, making us unable to stop stimulating each other once we started having sex.

Watching Yubin’s backside as she received my penis while lying face down, I kneaded her white buttocks with my hands. When the movements paused, she turned her waist to increase the stimulation.

“Eugh, Hheu! Unnh, Unnh!”

“It seems quite lewd.”

“Me?! Ahhh!”

Yubin contracted her vaginal walls to stimulate my penis and thrust it in again.

“Yes. Even though it’s my first time, I can be sure about this.”

“No. Me… Hieungh, Unnh, Haengh, Ah, Ahhhh!”

Despite denying her lewdness, her moans sounded like she was pretending every time I thrust into her, making me feel that this is how lewdness feels.

Although I also want to receive pleasure through sex, her figure, which seduces men, makes me unable to resist the temptation when she provokes me.

“Even today. I tried to sleep quietly, but you made me enter the blanket first.”

“That’s because I wanted to sleep together. Hieuk, Ee, Unnh! Ahung!”

She knew it was too late to use the excuse of wanting to sleep together, as her ears turned red.

“Then shall we stop?”

“Hieukk!!”

I pressed my glans hard against her cervix, and the intense pleasure from the pressure made her contract her vaginal walls strongly, causing her body to tremble.

“Aaauu, Ah, Heeuu!”

Yubin, immersed in the pleasure she felt only from my penis entering, was overwhelmed by the strong stimulation and couldn’t respond to my words.

Unable to endure the contraction of her vaginal walls, I also reached a strong climax inside her.

“!!”

Feeling like I was sucking in my semen, I released a lot and when I pulled out, semen flowed down onto the bed.

To rest until Yubin regained her senses, I sat down. As the penis giving pleasure left, I caught my breath, and the real Yubin turned over and faced me while I still had energy left in my penis, which she began to lick.

“Hieep, Cmuip.”

She licked away the semen and pre-cum on my penis and then put it in her mouth to suck properly.

“Chuuip, Cmuip. Uhm!”

I thought she was really going to devour me, but I was satisfied with the different pleasure she gave me through fellatio.

“I like it. You’re doing well.”

I don’t know where she learned such behavior, but it’s unlikely someone who isn’t lewd would do this willingly. I don’t know much since this is my first time with her and I haven’t had experience with other women, but generally, it’s not common.

“Huup, Huuum.”

While watching her earnestly suck my penis, I placed my hand on her head and started moving my hips slightly.

“Krup, Huup!”

She was surprised by my sudden movement and seemed to have trouble breathing due to the deep penetration. After waiting for her to catch her breath, I started sucking again, this time more slowly and delicately, matching Yubin’s rhythm.

As our breathing synchronized, Yubin could suck my penis more thoroughly, and I could feel her mouth entirely. The touch of her tongue when I inserted my penis particularly made me more sensitive.

“Yubin. I like it.”

Encouraging her, I stroked her head, and Yubin, stimulated by this, sucked more actively.

With continuous stimulation, the feeling of climax came quickly, and unable to hold back, I pressed down on Yubin’s head.

“Heeuuuip!!”

Surprised by the sudden deep thrust, I started cumming in her mouth.

It was my first time cumming outside the vagina, which itself was stimulating and exciting. It felt like I was doing something forbidden, although it’s common in adult videos, I hadn’t heard of anyone actually doing this.

“Wow, this is good?”

After cumming, I pulled out my penis, and Yubin remained still with the cum in her mouth.

“Doesn’t taste strange? You can spit it out.”

Though I hadn’t tasted it, I knew it would taste bitter from its distinctive smell. Yubin, who was trying it for the first time, would likely feel repulsed and want to spit it out. I prepared a tissue to help her.

“!”

Yubin slowly swallowed the semen in her mouth, unable to swallow it all at once due to the slippery sensation, so she did it in two swallows.

“Did you eat it?”

“Yeah… It tastes really weird.”

“Of course. I’ve never tasted it either.”

Feeling a mix of shock and pride that she had swallowed my semen, I wondered where she had learned this.

Hugging her, I stroked her head, and Yubin wrapped her arms around me.

“I wanted to make you happy, so I watched some videos.”

I couldn’t tell if she did this intentionally or instinctively, but one thing was clear: Yubin was a genius at stimulating me. No man would be unaffected by such words.

“You watched adult videos to have sex with me?”

“……”

Embarrassed to answer, she nodded her head while still hugging me.

I brushed her red hair with my hand and stroked her head.

“Did you learn anything else?”

Assuming she didn’t just look at one thing, I asked, and she let go of the hug.

Sitting, I waited for her next move. She turned around and knelt, presenting her buttocks to me.

In a kneeling position, she confirmed the position of my penis between her legs and spread her vagina with her hand, aligning the glans.

“Is this how it’s done?”

“No!”

Suddenly, she urgently said no when I tried to help her position herself. I waited for her to calm down, still blushing.

“This is only me moving. Older Brother shouldn’t move.”

“Yes, understood.”

Though I could move freely, I decided not to, respecting her wish to give me pleasure solely with her strength. I wasn’t sure how long my patience would last, but I’d try until I couldn’t anymore.

Yubin aligned the penis and lowered her waist, letting the penis enter her vagina.

“Heeuuung!!”

In a rear-entry position, she sat alone, and I focused solely on her movements, not moving at all.

“Aaah, Ah, Anng, Ahhh, Ahhh!”

She braced herself with her hands on the bed and continuously stimulated my deeply inserted penis by moving her waist.

Though there was no back-and-forth motion, the fact that she moved her waist enthusiastically was highly stimulating.

“Are you okay?”

“It’s fine. Hauu! How about Older Brother? Are you feeling good?”

“Yes. I feel great.”

Looking back at me with sincere emotion, I answered, and encouraged by my response, Yubin moved her waist actively, pleasing me.

Though I wanted to move, I tried to control my urges and instinctively moved my waist.

“Heeuht, Hee, Haung! Ahhhh!”

Focusing on her waist movements, Yubin noticed I was slowly pushing up and didn’t say anything, interpreting it as permission to intensify the movements.

“Ahh! Ahhh! Ahhhh!!”

When I suddenly pushed up forcefully, Yubin tried to endure the climax by tightening her waist muscles. The stronger the muscles contracted, the more intensely I moved.

Finally, unable to hold back, I pulled out and laid her down again, inserting my penis back into her vagina.

“Aaaah, Haaang! I was trying to make you feel good.”

Though she seemed a bit annoyed at not following the plan, I didn’t see any further reactions from her.

Lowering my body to hug her, she naturally lifted her buttocks slightly.

In the missionary position, we embraced each other, and I started rough piston movements.

The strong, pressing motions made loud moans, and I moved my waist uncontrollably while holding her.

“Haung, Ah, Ahhhh! Ahhhh!”

Listening to Yubin’s loud moans, I continued the piston movements recklessly, like a monkey discovering sexual pleasure for the first time.

Moving my waist mindlessly, I lost track of how many times I climaxed and moved again. Only when I heard her voice break did I regain some sense.

“Oh, Older Brother… Just a little… Rest… Hieuu!!”

Her sincere request for a break was due to the continuous rough movements, but even after hearing her voice and regaining some consciousness, I didn’t stop moving.

“Ah, Unnh, Heeu, Nn! I want to rest… Older Brother. Older Brother…! Heeuu!!”

I thrust deeply again and climaxed. I ejaculated again into her already full uterus, and immediately after, I moved again.

Finally stopping at around 3 AM, exhausted and thirsty, I stopped moving and got water from the fridge.

Exhausted from the non-stop sex, Yubin lay still on the bed.

“Yubin. Do you want some water?”

“Uh…”

With a tired voice, I inserted my penis again into her vagina.

“Hieeuu!!”

Surprised by the sudden intrusion, I kissed her while she had water in her mouth.

“Huup!”

Feeding her water through a kiss, I held her again, not tiring of her, and continued having sex.

The last memory was that the sun rose while we were having sex, and only then did we stop and fall asleep.

Waking up, Yubin complained about lower back pain, and I knelt down involuntarily, realizing this was punishment.

When Yubin’s work shift was almost over, she went to work, and I thought about it while looking at the wall.

‘I am an ape.’
