First Lesson (2)
I let out a soft “Hngh…” as I sat in the classroom chair, surrendering my body to Siwoo’s touch. From behind me, his hands began to move—slowly, deliberately.
“Hic… hngh…”
When developing a girl’s breasts, it was common sense to moan in a way that could arouse a man. Yet the shame kept me from crying out properly. I tried my hardest to keep my mouth shut, but the words still slipped free.
“Haah… Why is this body… hngh… so sensitive…?”
Even though he was only touching my breasts, the pleasure was beyond description. Was this the game’s correction at work? It was nothing like what I’d felt as a man—an overwhelming, indescribable sensation flooded through me. That was why the moans kept escaping no matter how tightly I pressed my lips together.
“Aren’t you going to take your clothes off?”
“Ah…? S-sorry.”
I couldn’t even moan properly, and I hadn’t even undressed for class. This was the absolute worst. A girl was supposed to make sure a man could get excited at any moment… Of course I was originally a man, but right now my body was female, so I had to follow the rules… right?
I peeled off the school uniform I was wearing. In nothing but my underwear, I felt exposed.
‘So this is what’s attached to me now…’
The structure was completely different from a man’s. And on this body sat a bra that seemed to declare it would allow nothing further—yet for that very reason, it looked all the more beautiful. Wearing a pure white bra felt strangely surreal.
“You’re not taking this off either?”
“Hic… This too…?”
Siwoo asked while firmly pressing down on the nipple atop my breast. I wanted to take it off despite the embarrassment, but some unknown barrier held me back.
‘I have to take it off… but… but… something feels wrong.’
When a man told you to remove even your bra, it meant he truly cared about you and wanted to develop you properly. Any other girl would have been so grateful she’d bow in thanks. Yet the words wouldn’t leave my mouth. Taking this off felt like… like I was abandoning something as a man.
“Sehee, take off that underwear. ‘You want to, don’t you?’”
The moment those words echoed in my head, all my hesitation vanished in an instant. My mind felt clearer somehow.
That’s right. Siwoo was helping me like this—refusing would be against all common decency. With that thought, I tossed the forgotten underwear aside.
“Our Sehee really does look like she needs to be fucked right away.”
“Hah…!”
He laid me down properly and began to twist my nipples little by little.
“Haang… ngh… ugh… hnnngh…”
My mind went completely white.
“Haaaaaaaahng!”
What the hell was that…? I’d never felt anything like it. I could feel my thighs growing slick and wet. Even though I’d just come, the arousal didn’t subside—instead, my body grew even hotter.
“Haah… No matter how much the scenario demands it, I can’t hold back anymore. Let’s pop that cherry first.”
“Hnnngh… Huh?”
Cherry…? What did “pop that cherry” mean? It sounded vaguely familiar, yet it felt like the word had been deliberately erased from my mind.
‘If I don’t know something, I should ask.’
I didn’t know who had said it, but they’d claimed that not knowing wasn’t a sin—pretending you did was what was bad. With my sensitive body and slightly damp lower half making me feel strange, and tears pooling in my eyes, I asked.
I still needed to be careful, but from what I’d seen so far he’d only been kind, so it should be fine.
“Um… Siwoo? What does… popping a cherry mean?”
“Huh? Hahaha, so the ‘deletion of female-related sexual knowledge’ works like this? That’s hilarious.”
What? Why was he laughing? It felt like he was mocking me, and it left a really bad taste in my mouth. Damn it, not knowing isn’t a crime!
“Sehee, popping a cherry means putting my cock inside this little hole right here.”
……
“You… you pervert!”
The only reason I’d stayed still under his touch until now was because it was part of the lesson. Even in a game, you had to participate seriously in class, so I’d had no choice. But suddenly he wanted to put it in? A man’s thing… inside my body? Doing something like that during class was the kind of thing only a real pervert would do!
“W-wait—”
“Don’t resist.”
In an instant he seized my wrists, pinning them so tightly I couldn’t move at all.
‘These hands…’
I could break free from a grip like this easily. I strained with all my strength, but the wrists in his grasp showed no sign of loosening. Had becoming a woman made me this weak?
“I said don’t resist.”
His eyes were dead serious. He looked like a wolf staring at its prey. And I… I was like a helpless lamb waiting to be devoured.
No, no, no. I couldn’t let something like that inside my body.
I thought about asking the other students for help, but speaking to anyone who wasn’t your partner during class publicly meant declaring you wanted to become a sex slave. That was something I absolutely refused to do.
“W-wait, I’m still a virgin…”
I’d never done it even as a man, and now I was supposed to experience it first as a woman…? Faced with an act I’d never tried—especially as a girl—my hands began to tremble as I imagined what was about to happen.
“Sehee, in that case you should say you’re a virgin.”
“I’m a man!”
“There you go again. Oh, is this your first time?”
Again? What did he mean, again? And now that I thought about it, how did he even know my name? Looking back, the whole situation had been strange from the start, but I didn’t have time to worry about that right now.
“Cute. So there’s a special taste to virgins, huh? If you really don’t want it, how about a paizuri instead? If I’m satisfied, I won’t put it in today. Believe it or not, I always keep my promises.”
“Paizuri?”
He pulled down his pants, revealing an enormous cock.
‘…How is it so big?’
It was a wonder the thing even fit inside his pants. It was massive. Mine had never been anywhere near that size… What the hell was that thing?
“Suck it.”
‘He wants me to suck… that?’
I didn’t want to suck it. I didn’t even want to look at it. Any real woman would have gone crazy for it, but I was a man. There was no way I could do something like—
‘What’s going on?’
Was it because my body was female now? It should have filled me with nothing but disgust… yet instead it smelled sweet and made me even more aroused.
“J-just… once.”
That’s right. This was nothing more than something I had no choice but to do. If I were a real woman, it would be common sense to service a man the moment he showed his cock. Since I looked like a girl right now… I was only doing what I had to. It definitely wasn’t because I actually wanted to suck it.
“Mmph… haaumph…”
I opened my mouth wide and took the huge cock inside. Then I began licking it little by little with my tongue.
‘I’m… a man…’
An inexplicable sense of guilt washed over me, yet at the same time my body burned as if set on fire. I could feel my lower lips growing wet again.
“Slurp… Hurry… hngh… and cum already…”
“Put more effort into it.”
How long was I supposed to keep sucking? His cock was so big it wouldn’t even fit all the way in my mouth. Had my mouth gotten smaller…? Either way, it made sucking the whole thing at once impossible.
“It’s too big!”
“Pfft.”
Why was he laughing?! If his cock weren’t so ridiculously huge—or if my mouth were just a little bigger—I could have made him cum right away. It wounded my pride for no reason.
‘Is this really something to get prideful about?’
It probably wasn’t that important. Shaking the thought away, I focused on sucking again.
“Oh, I might be starting to feel it. Come closer and suck harder.”
“W-wait!”
Before I could resist, he grabbed a fistful of my hair and yanked my face toward him. I couldn’t breathe… But he showed no mercy, shoving his cock deep into my mouth until it filled me all the way to my throat.
—Spurt
“Kgh! Cough, cough!”
A thick, strangely scented liquid flooded my mouth.
“Ugh!”
Was that… semen? No matter how I thought about it, the stuff that smelled like night-blooming flowers could only be semen. I’d expected it when he told me to suck, but experiencing it for real was on another level.
“Our Sehee is such a good girl—she didn’t forget this part. Is it engraved in your head or something? By the way, do you know what paizuri is?”
“Huh?”
You were the one who told me to suck it. You even showed me that huge thing… so obviously I thought you meant—didn’t I?
“Paizuri means rubbing my cock between those breasts of yours, understand?”
“Eh?”
Wait, then…
“What the hell have I been doing until now…?”
“It was all pointless.”
“You… you fraud!”
This was invalid! He was the one who lied in the first place! This was entirely his fault, not mine!
“Don’t want to? Then we can just continue what we were doing earlier.”
I flinched. But… that was even worse.
‘Yeah… maybe doing something I’ve already tried would be better?’
Running away seemed impossible. Compared to that, rubbing it between my breasts felt far less terrifying. Besides, I couldn’t even imagine something that huge going inside me.
“Fine… I’ll do it.”
With those words, I took his cock—which had grown rock-hard again—and slid it between my breasts.
