### Episode 11

They say there’s a taste to your first kiss. Some say it’s a fresh, fruity flavor, while others claim it tastes like the dinner you shared.

Today, I finally understood what they meant by the varying descriptions of a first kiss. My first kiss had no distinct taste. However, the moment our lips touched, the sensation was incredibly soft, and I felt strongly that I would never forget this feeling.

After the kiss, I wanted to take things further, but Yubin’s words stopped me in my tracks.

“I think it’s better to wash up first.”

If it were up to me alone, I would’ve gone ahead immediately. But sex isn’t something you do by yourself. Doing it alone would be no different from masturbation, and it would be disrespectful to Yubin.

Moreover, unlike men, who are straightforward and instinctive in the face of desire, women need preparation. Even someone like me, who’s inexperienced and just lost his virginity, knows that much.

Honestly, I wanted to suggest we shower together, but seeing Yubin’s bright red face, even while we were lying side by side on the bed fully clothed, I figured she’d be too embarrassed if we went in together.

“I’ll go wash up first.”

Before I lost control and ignored Yubin’s words, I grabbed a robe and headed to the bathroom.

The decisive moment is right around the corner, but I need to stay calm. If I get too excited and act recklessly, there’s nothing more embarrassing in the world.

Here I was, lying on a bed in a motel with a girl I knew liked me, on a rainy day. To top it off, she’s undeniably beautiful with a mesmerizing figure, and she’s showing me sides of herself I’ve never seen before.

Even after entering the bathroom to wash up as Yubin wanted, I think I held myself together remarkably well. I even mentally applauded myself, thinking I deserved some recognition for my restraint.

If someone were watching, they might’ve said, “Is that idiot really holding back?” But think rationally. If I acted like a wild beast without considering her feelings, and ended up getting slapped or worse, who could I blame? Even if I didn’t get slapped, would she want to do it again if her first memory with me was like that?

It might just be my assumption that we’ll do it again, but who knows what the future holds? Whether you’re from Earth or another planet, the future is never set in stone.

When I came out of the shower, Yubin was sitting quietly on the bed, holding a white robe.

As our eyes met—both of us in robes—we blushed and awkwardly avoided each other’s gazes.

It wasn’t because we didn’t like each other. It was just that the atmosphere felt incredibly awkward.

“I, um, washed up.”

“Huh? Oh, okay.”

I sat down on the opposite side and spoke abruptly, while Yubin, her face still red, headed into the bathroom.

When I glanced toward the bathroom, I was shocked and understood why Yubin had been so hesitant.

The bathroom walls were made of translucent glass, so Yubin’s silhouette was faintly visible. It wasn’t fully clear, but that made it even more embarrassing, and my face heated up.

Yubin, aware that her silhouette could be seen, moved as little as possible while washing up. Meanwhile, I tried to calm myself by reciting the national anthem in my head. I was glad I’d memorized it.

A while later, the shower turned off, and Yubin came out of the bathroom wearing the same robe.

Even in clothes, her figure was noticeable, but in the robe, it was unexpectedly more striking. A few drops of water rolled down her face and into the cleavage visible through the robe, and I couldn’t look away.

Realizing my mistake, I quickly raised my head and met Yubin’s still-blushing face. Her damp, long red hair felt endlessly alluring, and her clear red eyes looked like jewels.

“Let me dry your hair.”

“Okay.”

The cheerful conversations we had while shopping were nowhere to be found. A heavy silence lingered between us. Both Yubin and I knew what was coming next, so we couldn’t look each other in the eye, and anything we said felt awkward.

I went behind Yubin, who was sitting at the vanity, and took out the hairdryer to dry her wet hair. Her long hair was lush, and its softness felt pleasant to the touch.

“It’s pretty.”

I blurted out my thoughts, admiring even a single strand of her hair. Yubin, who had been sitting quietly, jolted in surprise.

“Huh?!”

Her face, which had started to calm down, turned bright red again, and I couldn’t help but laugh.

“Pfft!”

“W-what are you laughing at?!”

Yubin turned around, her face red, and our eyes met.

“You’re just so cute.”

I tousled the bangs I had just dried with the hairdryer, and Yubin, pressing her bangs with her hand and lightly biting her lower lip, smiled before looking back at the mirror.

After drying Yubin’s hair and turning off the hairdryer, the only sound left was the rain outside.

Even though it’s our first time, it’s good to stay composed as an adult would.

And then I tripped over the rug under the vanity chair and fell onto the bed.

“Oppa?!”

Yubin, startled by my sudden fall, got up from the chair and approached me as I lay face down on the bed. I was too embarrassed to face her, but when I turned my head, our eyes met. I don’t know how many times we’ve locked eyes today, but each time feels just as intense as the first.

“Pfft.”

“What? You scared me.”

While the fall was absurd, seeing Yubin genuinely worried made me laugh uncontrollably.

I got up and sat on the bed, and we faced each other, slowly closing the distance. The 20 centimeters between us felt like an eternity.

When our lips touched again, I remembered the feeling of our first kiss. Yubin wrapped her arms around my neck, and I laid her down on the bed.

“Hff…”

Yubin gasped as the kiss deepened, our tongues intertwining in an instant. I let go of the arm I had wrapped around her neck and intertwined our fingers instead. Her fingers brushed against mine as she fidgeted during the kiss.

“Hm! Mmm!”

Her breath escaped between our lips as we kissed passionately. Hearing the kind of alluring moans I’d only ever heard in adult videos in real life set my mind on fire. When I pulled away, I looked at her face.

Her flushed cheeks, as red as her hair and eyes, excited me just by looking at them. It was as if she was calling out to me.

“Don’t stare so much…”

She tried to cover her reddened face with her hand, but I grabbed it, preventing her from hiding. I took in her thoroughly embarrassed expression.

“S-stop looking!”

Yubin suddenly squeezed her eyes shut as I stared intently at her face.

It was like a child playing hide-and-seek, thinking if they couldn’t see the other person, the other person couldn’t see them either.

“Alright, I’ll stop looking.”

I deliberately averted my gaze, and I could feel her eyes on me. She pulled one of her hands from mine and poked my cheek.

“What?”

I asked without looking at her.

“You can look now.”

Our eyes met again, and I felt like I’d reached my limit. I stood up and took off my robe.

My erect member, which had been hidden under the robe, was now exposed in front of her. Yubin, who had been looking at me, fixed her gaze on it.

“Yubin?”

“H-huh?!”

She seemed to snap out of it, startled, and looked up at me.

“The robe. Shouldn’t you take it off soon?”

I pointed to the robe still covering her body, and her hand, which had been about to untie the belt, stopped.

“Can’t you do it for me?”

“Sure.”

There was no reason to refuse her request, so I immediately agreed and untied the belt. The robe covering her body loosened, and I slowly opened it, careful not to startle her.

And then, I was momentarily stunned by the beautiful nude figure before me.

Though I didn’t know the exact measurements, her breasts looked too large to fit in one hand. Her pink nipples, her slim waist, her clearly defined pelvis, and her smooth, hairless secret area.

I swallowed hard as I admired Yubin’s beautiful body, feeling the tension in my member grow.

I grabbed her legs, which were lying still and sensing my gaze, and spread them apart. Though she was embarrassed, she followed the guidance of my hands.

We fell silent, and I used my hands to spread her pink, moist inner flesh apart. Eventually, overwhelmed by embarrassment, Yubin covered her face with her hands.

“Mmm, oppa. Can you turn off the lights?”

“Well… it’s my first time, so I might not do well.”

Honesty slipped out even though I didn’t need to say it. Thinking about her embarrassment, turning off the lights might be considerate, but sadly, this was my first experience, and I wasn’t sure if I could do well, let alone make it enjoyable. Turning off the lights was a bit difficult.

Hearing that it was my first time, Yubin smiled at me.

“That’s a relief.”

“What is?”

“It’s my first time too.”

We were each other’s firsts, and we ended up laughing.

We had been worried about disappointing each other with our inexperience, and the tension made it hard to speak.

But knowing we were both first-timers, the inexperience didn’t matter anymore. Just thinking about embracing each other sincerely eased the tension.

“I see. It’s my first time, but I’ll do my best not to hurt you.”

“I’ll try my best to make you feel good too.”

I held my member and pressed it against her wet entrance. As I searched for the right angle, rubbing the tip against her, Yubin’s juices coated my member, and she let out a moan she had been holding back.

“Mmm, ah! Oppa… hurry, please.”

Her delicate voice was a stimulant to me. I tried to calm myself down internally, but I couldn’t help the rising emotions.

When I found the right position, our eyes met, and Yubin, realizing it was time, clenched her hands between her breasts. Slowly pushing my hips forward, my hard member entered her, and Yubin trembled at the unfamiliar sensation.

“Ah, mmm! Ah!”

When about a third of my member was inside, I pressed my hips closer, pushing deeper, and Yubin’s moans, which she had been trying to suppress, finally burst out.

“Ahhhh!”

“Are you okay? Does it hurt?”

There’s a saying that the first time is painful. Not knowing how much it would hurt, I asked Yubin while keeping my member inside her. She looked at me with watery eyes, exhaling hot breaths.

“Hah, ahh… it’s fine. It doesn’t hurt at all.”

I kissed her lightly as she smiled. With my member inserted, we were completely pressed against each other, and her soft skin, fresh from a shower, naturally drew my hands.

I grabbed her large breasts and gently massaged them, feeling their volume that couldn’t fit in one hand.

“Ahh, mmm, ah!”

Though she said it didn’t hurt, I wanted to wait a bit for her to get used to the sensation, but my hips moved instinctively.

The pushing motion was unfamiliar, but I moved carefully for Yubin, who had allowed me this.

The wet walls of her vagina slid smoothly against my member, guiding my thrusts, and the faint sound of our skin rubbing together could be heard.

“Ahh! Hahhh. Ahh…! Oppa!”

Yubin, with her legs spread, continued to moan as she gripped the bedsheets. Wanting to make her feel good, I moved my hips even harder.

The warm body temperature and the slippery walls of her vagina were intoxicating. My first sexual experience was on a whole different level from what I had imagined.

“How is it?”

I held back my body, which wanted to move roughly, and whispered softly to her, who was moaning and trembling.

“Mmm, ahh! Ahh! It’s good. Oppa moving inside me… ahh!”

Who said the first time was painful? Who said you’d finish quickly the first time?

Yubin wasn’t in pain at all; she was moaning with a blissful expression, and I was overwhelmed with the desire to hold her even closer.

Just discovering physical pleasure, we were getting to know each other by feeling each other’s skin and body heat.

While massaging her large, swaying breasts, I caressed her face with my other hand. She placed her hand, which had been gripping the sheet, on the back of my hand that was touching her face and smiled.

“Ahh, mm! Oppa. Does it feel good?”

“Yeah. It’s great. The best.”

I put more strength into my thrusts, moving my hips more intensely, and Yubin panted, letting out louder moans.

“Ahhhh! Ahh! I feel good too. I didn’t know sex could feel this amazing.”

“I didn’t know!”

I felt the same way. It seemed like all my mind and heart were being taken away by Yubin in this first experience. No matter how much I moved my waist, I didn’t realize it could hurt, and Yubin’s body, rubbing against me with each movement, was just so soft.

“Older Brother will put in the effort. Feel it to your heart’s content. I’ll make Yubin feel good!”

Every time I heard her voice and saw her face, I couldn’t control my rising excitement, and the speed of my penis moving back and forth increased. The sticky sound of flesh rubbing against flesh mixed with the sound of rain outside the window, filling the room.

“Ahh!! Aah! Mmph! It’s my first time, really my first time. It feels so good, it’s almost strange.”

Was it because our mutual desire made us unable to feel the initial clumsiness?

Or is sex itself supposed to feel this good?

I couldn’t tell the reason. But as I held Yubin, I felt pleasure rising to the top of my head, and Yubin also let out pleasurable moans and panted with each of my movements.

“Yubin! Slowly!”

Feeling the urge to ejaculate deep inside, I tensed my penis, and Yubin, feeling it swell slightly in her belly, moved her waist in sync with my movements.

“Hahh! I feel like I’m going to lose it too! I can’t think of anything! Heeek!!”

As I pushed my penis in deep, Yubin arched her waist.

“Mmmph, hmph! Hahh!”

Unable to withstand the sudden pressure clamping down on my penis, I came inside Yubin.

My waist trembled, and I could feel that I was ejaculating more than when I masturbated.

“Ahh, hmph! Hahh!”

I watched Yubin, trembling and lost in the climax she had just experienced for the first time.

Even though she could feel my gaze, Yubin, shocked by the unexpected intensity of her climax, trembled violently and gradually calmed down, her grip on the bedsheet loosening.

“Hahh… Haa. Older Brother….”

Her rough breathing gradually stabilized, and seeing her breath calm down, I stroked her head.

“How was it?”

“It was good.”

Seeing Yubin smile and answer, I felt something was off. I stared at her intently and then opened my mouth.

“Do you want something?”

During sex, it’s good to communicate a lot and ask what the other person wants. I don’t remember where I heard it, but I recalled that it’s better not to think of it as just a physical act, but to see what the other person wants and either talk about it or fulfill their desires. Wondering if Yubin wanted something more, I didn’t hesitate to ask.

Seeing Yubin’s face turn red as she avoided my gaze, I decided to wait a bit until she spoke up. It didn’t take long, and Yubin hesitated before opening her mouth.

“Well, I’d like it if you could hold me more while doing it…”

“Hold you more?”

“Yeah. Hold me tight.”

As Yubin said, I pulled her close until there was no gap between us, and Yubin also wrapped her arms around my neck and pressed close. Naturally, my penis went in deeper, and feeling the vaginal walls tighten, I lifted my waist once.

“Heeek!”

As the moan sounded right next to my ear, my waist moved naturally, and the pistoning started again.

“Hahh! Ahh! Older Brother…! If you move right away…! Haaah!”

Though Yubin had just reached her climax and her breathing had calmed down, her body’s sensitivity hadn’t subsided. She seemed to suggest taking a break, but this time, I couldn’t grant her request.

“How can I not move when it feels this good?”

Whispering this right next to Yubin’s ear, I felt her vaginal walls twitch.

“……Do you like hearing my voice?”

“Haaah, it’s not that… it’s just too close…”

“You don’t like being close? Didn’t you say you liked being held?”

“I do like it… Hahh! Ahh, haah!”

Feeling the strength in her arms wrapped around me, the pistoning gradually sped up.

“Hmph, ahh! Oh, Older Brother!”

Contrary to her earlier tone suggesting a break, Yubin accepted the pleasure I was giving her and let out moans.

“Do you want me to do more here?”

“Hahh! Ahh! Haaah!! Kiss… Hmph!”

As soon as I heard the word “kiss,” I didn’t wait for her to finish and pressed my lips against hers. Yubin was the first to intertwine her tongue, and as I matched her, we grew more and more excited.

“Mmmph, hmph! Ooh, hmph!”

With each break in our French kiss, Yubin let out moans. Her body, already sensitive from the earlier climax, became even more helpless in the face of pleasure, and I could feel that she was experiencing all the pleasure I was giving her through the tightening of her vaginal walls.

Even without words, our bodies’ reactions let us understand each other’s state to some extent, and wanting to feel this sensation more, I moved my waist roughly.

“Heeek!! Mmmph, hmph!!”

Being pressed close together, the sticky sound of flesh rubbing and the sound of our bodies colliding became even more vivid, and we didn’t stop moving, continuously feeling pleasure from each other.

“Hahh, ahh! Oh, Older Brother…! It’s too intense!”

The moment I pulled my lips away to catch my breath, Yubin let out a loud moan. Her expression, drenched in ecstasy, telling me it was too intense only sounded like a request to go harder, and the rougher my movements, the more I wanted to see Yubin revealing sides of herself she didn’t even know she had.

“Should I go gently?”

Having moved continuously, I was also out of breath.

“No, I like it like this! Haaah! Do as much as you want, Older Brother.”

Hearing words that inevitably stimulate any man, I squeezed out every ounce of strength and moved my waist roughly.

Having ejaculated once already, the urge didn’t come quickly, so I could move longer. On the other hand, Yubin’s sensitive body kept getting stimulated, and the tightening became more intense. Knowing that she was reaching climax again and again, I put more strength into my waist to give her a deeper climax.

Having just discovered sex, I didn’t have much technique. But Yubin was getting excited and feeling pleasure from my inexperienced movements, and that sight stimulated me even more.

“I’ll do as much as you want, so if there’s anything Yubin wants, just say it.”

“Yes! I’ll say everything… Haaah! Everything I want to do with Older Brother… Heeek, hmph!”

Watching Yubin continue to climax and moan with each of my movements, I suddenly stopped.

“Older Brother…?”

As the sudden halt in movement left her panting, Yubin opened her eyes wide like a startled rabbit and stared at me intently.

“You look tired, want to take a break?”

“…N-no.”

It was a playful remark, but Yubin’s face looked like she was about to cry. She wrapped her legs around my waist and moved her hips.

“Hmph, ahh! No. I don’t want to take a break. I want to have more sex with Older Brother!”

The pleasure she had been feeling suddenly stopped, and Yubin, her thoughts entirely focused on sex, wanted it even more than when we were moving roughly.

Seeing her like this, I couldn’t help but get excited again and resumed the pistoning, while Yubin held me tightly.

As we engaged in sex, the sounds Yubin made with each of my movements gradually changed, and her erotic moans were etched one by one into my mind.

“Hngg, ugh! Hhng! Oppa! It’s going in! Deep inside!”

“Because Yubin feels good! How could I not put it in!”

“Hyuk, ahhng!!”

I pushed my hips as close as possible and thrust deeply, making her body tremble and her hips twitch wildly.

“Did you feel it?”

“Ahh, haaahh!! It, it touched the deepest part…!”

My deeply inserted penis reached the innermost part of Yubin’s pussy. As it touched her cervix, it felt like electricity surged through her hips, bringing her immense pleasure.

Since I couldn’t just leave her in that state, I moved my hips rapidly while still touching her cervix.

“Hieek, ah, ahhng, ah, aht!!”

Every time my hips pushed in, Yubin felt like she was reaching her climax, losing her mind to the overwhelming pleasure. Her vaginal walls tightened as if trying to squeeze out my member.

Eventually, I ejaculated one more time while pressed tightly against her. Yubin, unable to even make a sound, breathed heavily through her clenched teeth, feeling her peak.

“Hut, ugh, hhng…!”

I gently pulled my body away to let Yubin rest comfortably.

“Are you okay?”

“Hhng, hhng! Haa… haa….”

As I spoke, her rationality seemed to return. She gasped for breath, her gaze, which had been vacant, now focused on me.

“It was… amazing.”

“Should we rest for a bit?”

I thought of letting Yubin rest for a moment, but as soon as I said that, her pupils shook.

“Rest?”

“I was thinking of taking a short break, but do you want to do more?”

“…There’s one thing, but if you’re tired, let’s rest for a bit.”

She moved her hips once.

“Ahhng!!”

“I’m still fine. What do you want to do?”

Yubin then raised her upper body while I was still inside her.

“Sitting…”

“Got it.”

I supported her hips with my hands and sat up properly. Yubin was now sitting on top of me, my penis still inside her pussy.

“Did you want to try this position?”

“……Yes.”

The girl who had been mindlessly having sex just moments ago was now blushing and acting shy.

With her hips supported by my hands, she began to move slowly. Since I was underneath, Yubin had to actively move her hips for us to have proper sex.

As my hips moved, Yubin, pressed tightly against me, moved hers as well.

Feeling the pressure and touch of her large breasts against my body, I was able to enjoy the sex even more.

“Haat, ahng, ahhng!”

Yubin’s moans, as she moved her hips while pressed against me, were right next to my ear this time.

Was this really her first time? The doubt that crossed my mind was resolved by the bloodstain left on the spot where Yubin had been lying earlier.

Even though it was her first time having sex, could it be that she felt this much because we were so compatible? As I continued piston-thrusting, feeling really good, and seeing Yubin moving with satisfaction, it seemed like we were indeed a good match.

“Haaahng! Ahhng! Oppa. Oppa!”

Seeing Yubin call out my name while moving her hips, I lifted my hips as much as I could while sitting.

“Why?”

“I like it. I like you, oppa! Hhng!”

As I responded to her call, she suddenly confessed again, and I couldn’t control the smile that formed on my lips.

“Me too.”

“Really? Hhng! You really do?”

“Yeah. I really do.”

I decided not to deny the feelings I sensed in Yubin’s heart and the emotions I felt. We could think about our positions and relationship later; there was no need to worry about it at least for now.

“So, you won’t leave?”

“Don’t go?”

“Yeah…. Don’t go.”

Yubin’s vigorous hip movements stopped, and she hugged me tightly, her body trembling.

“Don’t go anywhere. I’ll treat you well….”

I hugged her back as she trembled and whimpered while holding me.

I still didn’t know what circumstances Yubin was in. However, it seemed certain that loneliness was something terrifyingly incomparable for her.

“I won’t act selfishly or throw tantrums. I’ll do everything you want… so don’t leave me alone. I hate being alone….”

I looked into Yubin’s face as she hugged me tightly and kissed her while she was crying.

She closed her eyes tightly, responding to the kiss, and slowly began to move her hips again. I then laid her down.

“Don’t worry. I’m here now.”

“Hhng, hhk…! Yes.”

I wiped her tears and, to ease her anxiety, started rough piston-thrusting right away.

“Haaahng! Aht!”

As I thrust roughly, Yubin began to be consumed by pleasure once more, and I continuously gave her pleasure without stopping.

With Yubin, who had given me her first time and wanted to be with me, beneath me, moaning and moving her hips in sync with mine, I shook my hips to match her.

Feeling that I truly desired her right now, I moved my hips repeatedly without rest, ejaculating deep inside Yubin over and over.

30 minutes. 1 hour. 2 hours passed, and by dawn.

We were still having sex.

“Haaahht, uht! Hhng! Ahhng!!”

“How is it? Does this position feel good too?”

“Hyuk! Hut! It, it’s good! It’s reaching deep inside! My hips feel tingly!”

I lifted Yubin’s legs to the side and performed rough piston-thrusting while inserted. Yubin gripped the bedsheet tightly, breathing heavily and moaning.

“I’m coming again!”

“Hieeeek!!”

I pressed my hips tightly against her just before ejaculating, and Yubin also felt her climax as my member went deep again.

Feeling the slippery and warm tightness of her vaginal walls, I put strength into my tightly pressed hips.

I ejaculated inside her once more, unsure of how many times it had been, pulled out, and laid her down before lying down next to her.

“I’m exhausted….”

I don’t know how many times the average man on Earth has sex in one session, but I’m certain I’ve surpassed my limits today. Since Yubin, who was experiencing it for the first time, went this far, maybe those with more experience go even further? I feel like I’ve been defeated for no reason.

As I lay down next to her, Yubin leaned into my embrace, breathing heavily, and I held her with one arm while caressing her chest.

“Oppa. I’m too tired to do anymore.”

Thinking that my caressing was a signal that I wanted to go again, Yubin looked at me with an apologetic expression.

“I just wanted to touch you. I can’t do it anymore either.”

While I was proud of myself for not stopping once during over two hours of sex, I couldn’t help but admire Yubin. I felt that I’d need to put in more effort if we were to have more sex in the future.

As I lay still, intending to rest, both Yubin’s and my stomachs growled simultaneously, as if demanding food.

Come to think of it, we hadn’t eaten dinner and had only been having sex until this hour.

“Should we eat?”

“Yes!”

We looked at a delivery app together, chose some food, and after ordering, with nothing else to do,

we had sex again.

Yubin was lying face down on the bed, her hips pressed tightly against mine as I inserted myself into her. I started pushing my hips deeper.

“Hhng, ngh, hmm!! It feels good… Ahh!”

It was funny how we had decided earlier that we couldn’t go any further, but here we were, having sex again. What was even funnier was that it wasn’t gentle—it was rough, as if something had happened that made us lose control.

“Can I do what I want this time?”

While thrusting into Yubin, who was lying face down, a certain position suddenly came to mind.

“Yeah. Let’s do what you want too.”

I lifted Yubin’s hips while she stayed face down, raising her butt higher.

“Wait, this position is a little embarrassing… Hhhng!!”

Without letting her finish, I started thrusting roughly again.

“You kept doing what you wanted earlier, so this time, I’ll do what I want. Is that okay?”

“Ahh!! It’s, it’s fine… Ahhh!!”

Even though we were already having sex, her walls tightened around me as if begging me to go deeper with each thrust. Responding to that, I couldn’t help but thrust harder.

“Let’s just do it until the food comes.”

“Who knows when it’ll come, ngh, hhng! Ahh!”

While kneading Yubin’s buttocks, I pushed myself deep into her, where she seemed to want me the most.

It didn’t take long for me to feel like I was going to cum. I deliberately held it back, which made my movements even more intense, causing Yubin to let out high-pitched moans that could pierce ears.

Holding back for a long time wasn’t possible for me, so the moment I reached my limit, I pushed my hips forward and came inside her again.

“Ahhh!! Oppa…!”

After cumming inside her once more, I pulled out, and the semen I had just released spilled out of her wet pussy. Seeing this, I immediately inserted myself again, and the heated sex seemed endless.

In the chaotic heat of the early morning, we kept wanting each other endlessly. Even when exhaustion hit, it was as if nothing had happened, and we embraced each other again, enjoying the newfound pleasure to the fullest.

We fell asleep without even knowing how long we had been having sex. It felt like we had fallen asleep before the sun rose.

I only remember that we indulged in pleasure to the point where I couldn’t recall exactly what time it was, how long it lasted, or how we did it.

And then morning came, and I woke up around 9 a.m.

“My back hurts…”

Yubin, feeling the aftermath of the rough sex last night, got up in a hunched posture.

“Are you okay… Oppa?”

I couldn’t even get out of bed due to the unbearable pain in my back. Everything comes with a price, but what was I thinking, thrusting all night without any technique?

“Save me.”

After eating breakfast in the early morning, we had sex again, but when Yubin said her back hurt, I minimized her movements and did all the work myself. That’s all I remember.

“Can you get up?”

“Just a second… Ugh!!”

As I tried to get up, a sharp muscle pain shot through my back, and I let out a short cry. Although my posture was awkward, I managed to get up with Yubin’s help.

“We need to be more careful from now on.”

Excited by our first time, we overdid it, and now I was experiencing pain I had never felt before. I resolved to be more cautious during sex for a while. Of course, I soon realized that this resolution was similar to saying you’d never drink again after a heavy night—it didn’t last long.

“We should shower and head out. I have work too.”

Yubin had a part-time job at the convenience store in the afternoon. I had forgotten about it until we had sex in the early morning. If I had known, I would’ve been more careful, even if it was our first time.

“Yeah, let’s shower and go.”

When I stepped out after showering, the weather was slightly cloudy but not raining, contrary to the forecast that predicted rain until the afternoon. It seemed the rain had come early and stopped sooner than expected.

“It’s not time for work yet, right?”

“No. I’ll go home, drop this off, change clothes, and then come out.”

She showed me the shopping bag containing the clothes I had gifted her yesterday.

“Alright. See you at the convenience store later.”

“Can you make it?”

She seemed worried about my back condition, even doubting if I could make it home. I felt a bit uneasy, but I thought I’d manage to get home if I took it slow.

“I’ll go.”

“…Alright. Be careful, and see you later.”

Yubin headed home first, and I dragged my aching back, taking slow, careful steps until I finally made it home.

After getting home and lying down, I started thinking a lot.

Yubin and I had become lovers, and I didn’t know how to handle my previous role of monitoring her. Last night, I thought everything would be fine, but now, as I thought about it more, I realized I might have gotten myself into a bigger mess than anticipated.

“What do I do?”

The worry didn’t leave my mind, and I couldn’t come up with a solution.

Yubin is Red from HunterKiller, and I’m a soldier from Spacystro. But Yubin doesn’t know my true identity, and even though we’ve become lovers, I can’t tell her that I’m from Spacystro.

“I don’t know!”

Since no solution came to mind, I decided I’d have to report to Luche later and figure something out. Should I even report that we’ve become lovers? I wondered, but soon it was time for Yubin to be at work, and I staggered toward the convenience store.

When I entered the store, there were no customers, and Yubin waved at me as soon as she saw me.

It still didn’t feel real that I had become lovers with her last night and had sex all night.

I waved back in response to her greeting and while picking a lunch box, I suddenly realized something.

‘We didn’t use protection last night.’

There’s no precedent for pregnancy between us, who are from space, and humans from Earth, but if it is possible, I’ve made a huge mistake.

What’s done is done. All I can do is hope it doesn’t happen, and if it does, hope it doesn’t take.

Still, since I don’t know what might happen in the future, I decided to at least buy some condoms sold at the convenience store after picking out my lunch box.

Without much thought, I placed them on the counter, and as Yubin scanned the barcode, she noticed the condoms.

“Oppa. These are…”

“I forgot last night, but just in case, I want to have some on hand.”

Blushing, Yubin quietly held the pack of condoms before looking up and staring straight into my eyes.

“Get three more.”

As Yubin instructed, I grabbed three more packs, ending up with four packs of condoms, each containing ten.

Around 4 a.m.

“…We really went at it. How many times did I cum?”

Lying next to A, who was breathing heavily, Red counted on her fingers.

“24, 25…. I lost count after 25.”

The emotions they had been holding back burst forth, and the two of them spent the entire night pouring those uncontrollable feelings into sex.

“We did it that many times?”

As the sensation of holding Red all night came back to him, A’s limp member began to regain strength.

“Let’s do it some more.”

Until they fell asleep, they continued to hold each other and kept having sex.
