Childhood Friend Who Sees the Future Utters Nonsense

153 – Side Story – Siyoon’s Birthday (3)

When she took off the clothes she was wearing, Yuna’s white skin covered by her underwear was revealed.

But that wasn’t the only thing that caught my eye. That was because Yuna’s underwear was quite different from usual.

It was the same black underwear I had when we first started dating, but the important parts were see-through, so I could see through them a little. Even my nipples, which were already erect, stood out.

From the black ribbon on the bra to the thin lace that seemed to cover her stomach, it felt like underwear that had been prepared for today.

“Ugh… Don’t stare like that. It’s embarrassing.”

“You wore it well, knowing it was embarrassing.”

“But, I thought you might like this kind of thing….”

Okay, okay, okay.

Honestly, I thought that no matter what kind of underwear I wear, my body will be supported so well that it won’t make much of a difference, but I think I need to change that mindset starting today.

When I see underwear made to seduce men so blatantly, I feel something different. How should I put it, it makes my blood boil.

But I couldn’t just rush in without any reason, so I was taking a moment to admire my girlfriend’s body and outfit while holding myself back. Suddenly, Yuna grabbed my hand and led it to her chest.

To be exact, above the small ribbon decorated in the center of the bra.

“Want to try solving this?”

“…a ribbon?”

“Yeah, this is my last gift for today.”

Oh, so that’s why it was a ribbon. You really prepared well.

Somehow, I felt even more nervous than when I opened the gift box earlier, and carefully pulled on the end of the ribbon. Then, with a squeaking sound, the string came loose and Yuna’s bra fell onto the bed.

I thought it was just a decorative ribbon, but who would have guessed that the ribbon was actually holding the bra in place? It was a production that made me exclaim in admiration.

“How is it…? Do you like my last gift?”

“Yeah, it’s night.”

“T, what kind of compliment is that…!”

In my opinion, it was the best compliment. In the first place, when someone came dressed so revealingly, what country’s law would scold them for saying that they were revealing? The law needs to be revised urgently.

Squishy.

“Whew! Ah, no… .”

“What doesn’t work?”

As I grabbed her ample breasts that were clearly visible, thinking that I couldn’t bear it any longer, a faint moan escaped Yuna’s mouth and she tried to push me away.

When I asked her, thinking that she didn’t want me to come all the way here and just look at her like a pie in the sky, Yuna slowly pulled my hand away from her chest and spoke.

“Oh, I’ll do everything today… so you just stay still.”

“There is no such thing as torture.”

“Rice, pervert. Do you want to touch my chest that much?”

“Isn’t that natural for a man?”

I shrugged my shoulders naturally, but decided to go along with Yuna’s request for now. I figured she probably had something else she wanted to do for me since it was my birthday.

“Do you want to lie down first?”

“huh.”

As I obediently lay down at Yuna’s words, the front of my pants, which had risen toward the ceiling, was clearly visible.

Of course, Yuna couldn’t have missed it either, so she blushed and slowly approached me in a cat pose.

And then he ran his hand over his bulging pants, then raised them, repeatedly teasing them. I don’t know how to put it, but it felt like he was cheering for Jaji to grow bigger.

Ssuk.

Then, Yuna grabbed the waistband of his pants and carefully pulled them down. When she saw the object that had grown so big that it seemed like it was going to pierce through his drawers, she swallowed in surprise. It was so quiet that I could hear the sound of him swallowing.

I really wanted to just throw Yuna over and do whatever I wanted, but on the other hand, I wanted to watch to see what she would do.

After some time had passed, Yuna pulled down the last piece of underwear and thrust her face toward my lower body with her mouth open.

“Chooo… .”

“Ugh…!?”

At that moment, I had the illusion that what I was seeing was an illusion.

That’s understandable, because our schedules didn’t match up after our first relationship, we didn’t have that many relationships, but I never asked Yuna to do this kind of play before.

If I had to be specific, it’s because I tend to be the one taking the lead and being the one to actively caress her in bed, and I also thought that girls would hate this kind of thing, so I didn’t ask for it on purpose.

But even though I hadn’t said anything, Yuna came forward and put my dick in her mouth. Just this sight alone made me feel like I was going to cum.

“Whew… . Haa, lick… . Slurp.”

Although it was a little awkward at first, the sight of her biting my large member with her small mouth, sometimes licking the shaft with her tongue, and continuing to caress me in various ways was incredibly erotic.

Yuna’s mouth was warm and wet, and it felt similar to when I put it directly into my v*gina, but different.

Sometimes, she would roll the glans around in her mouth, sucking it in with her tongue like it was candy, until her cheeks were swollen. When she did that and looked at me with her seductively widened eyes, I felt a strange sadistic desire welling up in me.

Even though I wasn’t really putting in any effort, I found myself out of breath as I watched Yuna passionately continuing the fellatio. And as I did so, I also began to feel the urge to ejaculate.

“Yuna, I think it’s going to come out…!”

I couldn’t just ejaculate in her mouth like this, so I was about to grab Yuna’s shoulder to pull her away while hurriedly trying to stop her.

Kuk.

“Paha… You can take it, just put it in your mouth…”

Yuna put her hand between my butt and the bed, firmly holding my face in place, and then took her lips off for a moment before speaking.

Then, he put the saliva-covered penis back into his mouth and continued to move it back and forth quickly enough to make his balls sag, urging him to ejaculate.

Seeing Yuna’s tongue movements becoming much more skillful and active than when we first started petting her, and her head moving as if exploring her v*gina, it became difficult to hold back any longer.

Purut. Pururuk!

“Ugh…!?”

In the end, when I grabbed Yuna’s hair, thrust my penis in, and spit out semen, I saw her open her eyes wide as if she was out of breath.

But despite that, Yuna held onto my waist until the end and didn’t open her mouth until the end. No, she even sucked and rolled the glans with her tongue in her mouth full of white fluid, as if telling me to pour out more.

After a long time, when the matter was over, I took the object out of Yuna’s mouth and hurriedly reached for the tissue that was on the nightstand.

“Yuna, spit it out quickly….”

Gulp.

And then, just as I was about to pick out a few and hand them over, I heard Yuna’s throat gurgle and a sound like she was swallowing something. Small, but clear.

no way.

“Ugh, it doesn’t taste good. In the video I saw a while ago, it looked delicious… .”

“…video?”

I was momentarily taken aback by Yuna’s muttering.

What the hell did he watch? Did he watch porn to practice something like this?

Sizzle.

Without even being able to express her doubt, Yuna opened the condom wrapper she had. Then she came over to me, gently caressed my groin area with her hands, and lightly kissed the tip of my penis.

Every time that happened, I would blankly watch the shaking Yusil, and before I knew it, the place that had shrunk expanded again.

“You fought so hard and then you grew up like this… You pervert.”

Seeing that sight, Yuna smiled as if she couldn’t stop herself, pursed her lips while still holding the condom in her mouth, and very slowly swallowed the penis.

As soon as I pulled my lips away, I saw something wrapped in a translucent condom.

“Where on earth did you learn this?”

“Porn videos and… this and that? I even practiced secretly with cucumbers at the dorm.”

“… … .”

Thinking of Yuna, who had locked herself in her dorm room and was practicing alone with a cucumber, felt absurd, but also a strange sense of guilt welling up inside her, making her feel even stronger.

Although I would like to continue the next step right away, I was thinking that I would need foreplay this time, so I was trying to approach Yuna.

“laugh….”

Suddenly, Yuna turned her back and lay down on the floor. She was a little embarrassed by the position of her butt facing me, and she groaned softly.

When I lifted her lower body in that state, I could see her private parts covered by her black underwear. It didn’t stop there, Yuna pulled her underwear aside with her hand and showed me her private parts.

There was no need for foreplay there. The dripping love juice soaked the bedsheets, and the moist pubic hair gave off a silvery light.

I swallowed my saliva without realizing it, as I was struck by the blatant, almost obscene sight. The Han Yuna I knew would never do this, and the posture reminded me of an animal mating, and I felt an inexplicable desire welling up in me.

Snap.

As he approached Yuna, who was not opening her mouth as if there was no need to say anything more, and rubbed his penis against her v*gina, the sound of water coming from her excited love juice quietly echoed.

Was it because she was embarrassed that she got wet just from having her boyfriend’s dick in her mouth, not even being fondled? Yuna buried her face in the bedsheet and didn’t look at me.

Creak. Creak.

For some reason, I wanted to tease Yuna even more, so I barely resisted the urge to insert my penis and continued to rub it against her v*gina.

“Ugh…!”

Maybe it was because of the sound of the water getting louder each time, or maybe it was because she wanted to do it quickly, but Yuna eventually looked at me with a longing expression.

I wanted to see that face.

Having achieved such a satisfactory result, I thrust my waist forward as if to release the pent-up desire.

Swish!

“Whoaang!”

At the same time, a moan burst out of Yuna’s mouth that she couldn’t hold back.

As if it were a catalyst, it made my movements more intense.

Thud. Thud.

I continue to move back and forth, holding onto her plump buttocks that are shaped like an apple. The juice flowing out of Yuna’s v*gina soon fills my lower body, and every time it hits my thigh, the sound gradually becomes more lewd.

“Hah! Si, Siyoon…! Too, too much! Jo, slow down a little…!”

As the piston continued its rough movement, a voice that seemed to be asking for mercy came out of Yuna’s mouth.

But that behavior actually looked disgusting to me. While I was earnestly asking her to slow down, she was now moving her waist and shaking her butt from side to side in a demanding manner.

Is this really a signal to go easy? To my eyes, it just looks like a body movement to urge and seduce her.

“Fuck…!”

That’s probably why I almost swore without realizing it.

I was so annoyed by my girlfriend who always called me a pervert, but then when we actually started having s*x, she became even more desperate. I wanted to punish her, even if it was just a little.

slap!

Unable to resist that urge, he unconsciously struck Yuna’s shaking buttocks with his hand. It wasn’t very strong, but it was enough to make a pretty sharp impact.

“Ugh! Siyoon, it hurts…! Phew…!”

“You don’t seem to be in any pain at all?”

slap!

He squeezes her v*gina even harder, saying only that it hurts with his mouth.

At that moment, I was sure that Yuna was feeling more sensitive.

“You said I could do whatever I wanted today?”

“Whew…! T, but this is so perverted… .”

slap!

“Huh!?”

“You’re the pervert. How does that make you feel when you get hit by your boyfriend?”

“That, that’s… haang!”

Now, it seems like she has no intention of holding back her moans. Every time her butt was hit, Yuna let out a rougher breath and moved her hips with her tongue sticking out.

As I watched Yuna struggle without even being able to resist my touch, as if she were my property, my sadistic desires grew stronger and stronger. I wanted to see Yuna crave more and more pleasure.

Stab! Stab!

As the desire grew, the waist movements that represented it became faster and faster.

Yuna, who was barely able to keep her upper body upright by supporting herself with both arms just a moment ago, is now lying face down on the floor with only her buttocks raised.

Thud.

I grabbed Yuna’s arms and forcibly raised her upper body, then continued the back-and-forth motion as if I was hitting her from below.

“Whew! Hehe! Siyoon, I think I’m going to go…!”

“me too…!”

As we continued our intense relationship without ever slowing down, and increasing the speed from beginning to end, just like Yuna, I began to feel like I was starting to come to my senses.

As if to hasten the climax, I quickly increased my speed in one last spurt and crashed my lips against Yuna’s.

“Churup… . Chhup… .”

The moment when our tongues intertwined, and a pleasure completely different from what I felt in my lower body reached my brain, I felt something thrilling pass by my waist.

“Huh…!”

Boom! Boom!

I let out a faint sound from the dizzying pleasure and thrust my waist as if it were going to stab my uterus.

“Heh, ugh… I, I, I’m going…”

Yuna, who had both arms grabbed by me, couldn’t even resist and just squirted a lot of fluid.

Yuna, who was sprawled out on the suddenly damp blanket, let out an unidentifiable sound, “Ugh, ugh,” and shook her waist.

After seeing that sight, I came to my senses belatedly and scratched my face awkwardly, feeling a sense of doubt.

Um… was it too much?
