Side Story 5) Siblings’ Tale 14

Perhaps because I’d masturbated first thing in the morning, I came to my senses to find that time had flown by. Belatedly regaining my composure, I rushed out of my room and headed to the bathroom.

I ultimately didn’t clean my room, but no one would come in anyway. I had no choice but to resolve to clean it after returning from school.

After a quick shower, when I returned to my room, it was filled with the pungent smell of sex. But I couldn’t masturbate again right after just doing it, so I quickly changed into my school uniform and went out.

I wondered if the smell had seeped into my uniform, but it wasn’t too bad. When I went to the dining table, my family was sitting there waiting, just like yesterday.

Still, today passed without incident. Oppa didn’t play any tricks, and we had an ordinary breakfast like usual.

After breakfast, I went to school normally and attended classes as usual. Even after lunchtime, nothing particularly noteworthy happened.

Even when I glanced at Oppa, I didn’t sense anything unusual. The problem was on my end.

“Ugh…”

Just looking at Oppa made my heart race and my lower parts grow wet. I had no idea why this was happening, so I was slightly flustered. Was I really that easy? But upon reflection, it would be a stretch to say no.

Eventually, as soon as break time arrived, I ran to Oppa and whispered in his ear.

“O-Oppa.”

“What?”

Oppa looked at me with an innocent expression, as if he had no idea what I was talking about.

“…D-do you want me to… take care of your urges…?”

“……”

Even though I’d mustered up the courage to say it, Oppa just slightly opened his mouth, scratched his head, and made an awkward face. It was a bit ridiculous for him to act like this when he’d made me service him just yesterday.

But what could I do? I was the desperate one here.

Though I was too embarrassed to even lift my head from his reaction, I forcibly pulled Oppa up and took him outside. Then, we went into the nearest restroom.

I debated whether to go to the men’s or women’s restroom, but I figured the men’s would be better in case we got caught. The boys already knew Oppa did this kind of stuff anyway.

If we got caught in the girls’ restroom, both Oppa and I would be done for.

Once we reached the men’s restroom, I lost all reason and crouched in front of Oppa. Then, I immediately tried to pull down his zipper.

“Wait. You’re really going to do it?”

“You came here because you wanted to too…”

Even if I’d dragged him here, he could’ve resisted if he really didn’t want to. There was a significant difference in strength between Oppa and me, after all. But instead of resisting, he obediently followed. Acting surprised while secretly looking forward to it.

Unable to hold back any longer, I unzipped Oppa’s pants. Sure enough, his cock was already hard-proof he’d been anticipating this.

“Hey, wait a sec.”

“Mmm…♡ Why are you stopping me…♡”

It was too cruel to block me when his cock was right in front of me. I whined and rubbed my cheek against it, and Oppa, seeing me like this, patted my head and said:

“Do paizuri for me.”

“Paizuri?”

Now it was my turn to be surprised by the sudden request. I knew what paizuri was-using my breasts to pleasure his cock.

But I’d never practiced it before. That wasn’t the only problem, though. The biggest issue was that if I did paizuri, I wouldn’t be able to use my hands. My original plan was to suck his cock while fingering myself, but now I’d have to focus solely on servicing him, leaving me unsatisfied.

Of course, I had no reason to refuse since I’d offered to help with his urges. Reluctantly, I carefully took off my blouse, exposing my pale skin.

“I-I’ve never done this before…”

I meant that it might not feel good since it was my first time, but Oppa just said it was fine and told me to try. With no choice, I squeezed his cock between my breasts. Even though mine were big, his was even bigger, so it didn’t fully envelop him.

“…Ngh♡”

Still, there was something thrilling about it. I could feel his cock throbbing between my breasts, and the sensation made my heart race, getting me excited without realizing it.

I glanced up and saw Oppa signaling me to continue. Clumsily, I held my breasts and began rubbing them up and down.

Honestly, I didn’t think I was doing a great job. The only reason it felt somewhat good was because my breasts were big-if they were average-sized, it probably wouldn’t have worked at all.

“H-how is it…?”

I asked hesitantly, but got no answer. When I peeked at his face, Oppa looked slightly conflicted.

“Uh… Not bad, but, um…”

After a moment of hesitation, he cautiously added:

“Still better than my girlfriend, though.”

“…Your girlfriend did this for you too?”

“Huh? Yeah.”

“……”

Suddenly, irritation flared up. Maybe it wasn’t anger but something closer to frustration. Whatever it was, hearing that made me press my lips together and put all my effort into the paizuri.

Of course, trying hard didn’t magically make me better, so it wasn’t like I improved drastically. But Oppa seemed to feel differently.

Maybe because he’d been feeling mediocre sensations until now, the slightly improved paizuri made a difference. Either way, I focused harder than I ever had on a test, servicing his cock. After a while, I started getting the hang of it.

Thanks to that, I managed to make him cum before break time ended. His semen shot out with a *splat*, landing on my large breasts and covering my upper chest. But right now, I was happier about successfully pleasuring him than anything else.

“Hngg…♡ H-how was it…?”

“Oh… It was good.”

Even though I didn’t get to masturbate, finishing by licking his cock clean left me feeling oddly proud. I guess I really do have talent as an onahole, huh?

…Should I really be happy about that?

I was a little confused, but I didn’t have time to dwell on it. Break time was only 10 minutes, and that wasn’t long at all. I immediately went to the sink to wipe off the semen on my chest. Though it was thick, a little water made it easy to clean.

“Ah…”

The problem was that in my haste, my blouse had gotten slightly wet. It wasn’t soaked, just damp enough to look like an accident-but the issue was that my summer uniform only had underwear underneath.

And of course, the wet spot was right over my chest… After drying off, when I put my blouse back on, my pink bra was clearly visible through it.

My breasts were already big enough that my blouse clung tightly to me. Even a little sweat usually made it see-through, so getting it wet was a guaranteed show.

“Oh…”

Oppa, who was passing behind me, let out an admiring sound when he saw.

“Wh-what’s with that ‘oh’? Ugh, what do I do…?”

Of all days, we didn’t have P.E. today, so I hadn’t brought my gym clothes. I had nothing to change into-was I just supposed to let it dry like this?

But if I went back like this, I’d definitely draw stares. Not that I minded too much, but it would be a little uncomfortable…

“Hey.”

Just then, something was draped over my shoulders. When I turned to look, I saw Oppa had taken off his dress shirt and was now just wearing his T-shirt.

“H-huh?”

“If it bothers you, cover up with that.”

“……”

On my shoulders was Oppa’s dress shirt. It was much bigger and carried a faint scent of him. I clutched it tightly. What the hell? Why does this make my heart race?

With my face slightly flushed, I bowed my head and quietly thanked him.

“Th-thank…”

“Now give me something in return.”

“Huh?”

What? Out of nowhere?

But Oppa just grinned and poked my chest.

“Let’s trade. Your bra for this. Deal?”

“……”

This guy is seriously…

*

To cut to the chase-I did it. As a result, I ended up sitting in class wearing nothing underneath, my bare skin visible through my blouse. Oppa’s dress shirt kept me from being exposed, but one wrong move and I’d be caught.

Seriously, I thought he was being cool for once, but Oppa is still Oppa. Who even thinks of bartering at a time like this?

Even as I thought that, my heart was pounding. That trashiness is what makes him my Oppa. Still not putting his dick in me today.

“……”

Since when did “trashy” become defined by whether or not he fucks me? My standards have gotten weird.

“…Hngg♡”

Separate from that, Oppa’s scent lingered on the dress shirt. Of course it would-he’d been wearing it just moments ago.

Even though I didn’t get to masturbate or get fucked… this isn’t so bad either.
