Yumi-san started to breathe heavily, as her hands went up to her chest and down to her skirt respectively. Her left hand grabbed the mound on her chest while the other hand sneaked underneath her skirt, disappearing into that dark cave. Her face was flushed, her eyes half-lidded, and she let out a gasp upon giving her own breast a squeeze.

What the hell is she doing......

"Uhaa~!"

....no, don't answer that! I know exactly what she's doing, but why the hell would she do this in front of me?! I'm standing right here!

Out of basic human decency, I quickly turned my head to the side and even closed my eyes just to prevent myself from sneaking a peek. Yes, I know she's pretty and cute, but I'm not a pervert!

....Okay, fine! There have been a few times where I've watched certain 'videos' that, uh..... aren't considered safe for kids. I'm a guy, and I'm a teenager, alright? I can't help it if I get curious about those things! As far as I know, every boy goes through this!

Still, I have morals! At least I didn't watch those things in public! I'm not like Haru-san who lists down girls' measurements in his notebook for some reason! This is different!

"Y-Yumi-san....?! Why are you doing this here?!" I tried to say as the voice of reason for her before this blows up into something that's not safe for kids like those videos I've watched.

But she didn't even answer.

Instead, she kept on touching herself like I'm not even there.

"Iya~!"

Not even gonna try to figure out what caused her to let out that noise.

This is bad. I can feel the heat rushing to my own cheeks and if I don't calm myself down, the 'thing' down there will get hard and I won't be able to stop it. Ugh, crap, I can already feel it!

"....Uh, you know what? You can keep on doing this, I'll..... just go on ahead. I'll see you down there......"

If words won't get through Yumi-san, I'll just leave her here.....

......I feel kind of bad for wanting to leave her, but this is not my problem. If she wants to relieve herself, then she's free to do so. I'm not gonna judge her or anything.....

....but at least do it when I'm not around to watch!

I quickly grabbed my lunch box again and prepared to make a break for it but then I felt a warm hand grab my own, forcing me to stop.

I'm afraid of turning around right now because of what's waiting for me if I do. Behind me is a girl, one whom I just met, who suddenly decided that it's fine to masturbate when I'm— oof!

A sharp pain shot through my whole body as I fell, before I felt something heavy on top of me. I guess she tackled me to the ground and now she's sitting on me, right? Good thing I can still breathe normally.....

Great.

Now I can't even leave without pushing Yumi-san away!

Urrgh, I think I just hit my head after falling over.... my back, too. I should have used my elbows to take the fall instead.

After waiting for the pain in my head to subside, I looked up to see Yumi-san hovering above me, her face still completely red and her breathing was as ragged as ever. Come to think of it, didn't Usagi act like this earlier this morning? Her face was the same, and she was breathing heavily— no, focus! I'll think about Usagi later! Right now, I need to get Yumi-san off me before we do something we regret.

"Y-Yumi-sa— mmpphff?!"

I couldn't get the words I wanted to say because Yumi-san had leaned down and her lips pressed against mine.

.....My first kiss.

This girl, someone whom I've known for less than 24 hours, just took my first kiss.... just like that.

I have no idea whether to feel sad or happy right now.

While I'm left stupefied by her action, I felt her move her lips against mine slowly, causing my eyes to widen even more.

Okay, I admit that I'm enjoying this, but I can still think rationally! As much as it feels good to be kissed by a beautiful girl, this is still wrong. Yumi-san and I aren't even dating, nor are we a couple. We just met today, so we should not be doing this!

Because I'm stronger than her, I was able to push her away easily, but the redness on her face and her rate of breathing didn't change at all. She was looking down at me directly and as our eyes met, I felt unnerved by her gaze because it's like she's eating me alive.

"Yumi-san, what has gotten into you? What are you trying to do here?" I asked her for an answer while licking my wet lips.

....Fuck, I could still taste her essence on me. This isn't gonna help my case at all.

"Yumi-san, please answer me. What's going on?"

"Tenko-san....... t-touch me......" she spoke in a quiet but shy voice, making herself comfortable on my lap. Even though she said those words softly, they rang like a bell in my ears.

"....W-What?"

"Touch me....."

I could feel my jaw drop as I watched Yumi-san quickly unbutton her uniform before leaving it on the ground beside us. Her face burning red like a cherry, she was left wearing a white bra and nothing more above the waist.

I closed my eyes to try and prevent blood from rushing to my privates, but then I immediately felt something wet touch my pants. That can't be because of me.......

My gaze flew towards her pelvic area. As much as it embarrassed me to do such a thing, I lifted her skirt and I was treated to the sight of a girl's panties. I could feel my eyes almost leaving their sockets when I noticed her underwear was completely soaked at this point, which could only mean one thing.

Yumi-san was aroused.

"Tenko-san...... please......"

Yumi-san then grabbed my hand and brought it up to her bra-clad chest. I could feel my face about to explode in sheer embarrassment. But despite my conscience screaming at me to break free and push her away, I'm too dumbfounded to do anything.

She placed my hand on her left breast as I felt my pants become wetter because of her underwear. Her heart was pounding madly inside her chest, something that I can understand because I am sure that the same thing is happening to me.

....just what the hell do I do.....?

".....Tenko-san....."

Am I really going to do this?

Looking at her one more time, Yumi-san had a pleading look on her face now, similar to the one she showed me earlier.

Ugh, no matter what I think, this is still wrong! We're not supposed to be doing this!

"......Do it.... Tenko-san.... please....."

As if to prove her point, she grabbed my other hand and placed it on her right breast, causing her to moan again out of delight. Her sudden noise made me blush harder, making me lose my composure and causing blood to flow into my..... thing down there.....

AH, SCREW IT!

I can't take it anymore!

There's only so much that a regular guy like me can take before he loses control!

Propping myself on my elbows, I sat up so I'm face-to-face with Yumi-san. I stared at this girl who's sitting on my lap for a few moments and she did the same. I could feel her breath touching my face as I got closer to her lips, while sending her glances to make sure that she was fine with what I'm about to do.

And our lips met.

Now that I'm more aware of what's happening, I can take in the fact that I'm really kissing a girl right now. For the first time, if I may add. My first kiss may have been the one that happened earlier, but it was Yumi-san who initiated it and I was caught off guard by it.

We kissed for a few moments, doing my part by moving my lips along hers and just enjoying the act. I willingly pulled away afterwards, because I still have a grasp on reality. I know that we are running on a time limit because it's still lunch break and we have two remaining classes after this, so we need to leave this place as soon as possible.

However, I do know that I'll have to deal with Yumi-san's... problem right now and to do that, I have to deal with her.... arousal.

I looked down and noticed that my hands had never left her breasts, even though she was no longer holding them. While berating myself for not noticing that I could already remove them there if I wanted to, I believe that this is what I should do next.

"I'm.... going to take this off. I-I-Is that okay?" I asked, totally embarrassed about asking a girl if I could take off their bra.

God, I sound like a pervert with no sense of shame right now!

"S-Should I do it.....?"

I blinked in surprise at her question, before letting out a sigh of relief. Truth be told, I have no idea how to properly take off a girl's bra and if I have done it, who knows what might have happened. I might have snapped it off or something.....

"....Yeah, that would be helpful."

Yumi-san slowly reached behind her and with an audible snap, I could hear the bra being undone. I helped her remove the piece of underwear from her chest as I took a big gulp.

Two big mounds of flesh became visible to my eyes, each capped off with a pink tip that had become erect from what we had done so far.

A ravenous desire building within me wanted to grasp those breasts of hers and if I had to be honest, I can't deny that it's what I really wanted to do. The thing inside my pants can speak for itself.

Quickly but carefully, my hands latched onto her chest, taking both globes of flesh in my grasp.

"Ahhnn~!"

I took a moment to listen to the cute moan that escaped her mouth before I went back to work. I need to focus on making her release her, uhm...... fluids, yeah. That's what I.... that's what I have to do.

My heart kept on beating like crazy, but I tried to keep it together as my face approached her breasts. I'm certain that my face was also like a steaming tomato now and I couldn't be any more grateful that we were completely alone up here.

I took a deep gulp as my mouth descended on her breast, taking in as much flesh as I could.

"Uwaaa~!"

I threw all of my foreign thoughts to the back of my mind and focused on my task. Hearing Yumi-san's moan, I'm convinced that I'm doing good so far! Now I just have to keep this up until she's at her limit.

From her left mound, I switched over to the right but this time, my attention went to her erect nipple. I didn't waste time and wrapped my lips around the pink nub, while licking it up and down with my tongue. I could hear her moan louder than before and once again, I'm thankful that we're the only two people on this roof.

While I sucked on her breast and nipple, I took a quick glance at the watch on my right hand.

Crap.

We only have twenty minutes left until lunch break ends, and I still have a lot to do. Not only do I have to deal with an aroused Yumi-san, I also have to get a new change of clothes because my pants are stained with her fluids!

Not to mention, I have to find a fresh pair somewhere without being noticed by other students here!

I can't waste time..... I have to finish this as soon as possible.

Removing myself from her breast, I shifted my attention down to her lower regions, particularly her crotch that was hidden underneath her short black skirt.

"T-Tenko-san.... why did you—"

Sorry for stopping out of nowhere, Yumi-san, but I have to act quick if I want to save us both from being caught in the act.

Wrapping one arm around her, I slowly laid her down on the ground. Yumi-san didn't do anything against it at all, only following my actions despite the confused look on her face.

I grabbed the end of her skirt with both hands and flipped it over, her soaked underwear on full display once again. I reached out towards it but I stopped myself midway. Is this really okay? We just met today and now we're doing what only couples do when they're deep into their relationship.....

"Uhm.... Yumi-san.... can I......?"

With a red but clearly aroused face, she uttered, "I feel.... really good, Tenko-san...... please don't stop....."

....I guess that's my cue. She's fine with it, so maybe I should stop hesitating as well.

I reached out to grab her panties, before pulling them off her. Yumi-san actually lifted her legs to make it easier for me, but all it did was spread the wetness all over her skin. The scent of strawberries filled the air around me, and I can already see that it was both from her panties and her fountain down there.

Urgh, her smell didn't help one bit. It only made me even harder, to the point that I'm tempted to just bring it out and start masturbating but this isn't about me right now. I'm supposed to be handling Yumi-san, but I can't wait any longer.

I ignored the burning sensation in my cheeks as my attention locked towards her flowing entrance. Her special place was gushing with her fluids, and I can't deny that I'm drawn to how aroused and wet Yumi-san was.

Grabbing her thighs, I spread her legs apart and knelt in between them. Her scent became even stronger as I got closer. At this point, I know that deep down, I want to do this. Even if it's a primal desire or typical teenage hormones, I want to please her.

"Tell me if you want to stop." I looked up at Yumi-san for a moment, before turning back to her dripping entrance. Throwing my restraint out of the window, I descended my mouth on her lower lips.

"Kyaaa~!"

Nothing but her scent and taste filled my mind, as I was completely focused on pleasing this beautiful girl before me. She tasted like strawberries, which was exactly the same as her scent. No, that's not a bad thing and in fact, I'm enjoying this. What I normally see in adult sites was actually happening to me right now, and it almost felt like a dream.

This is the first time I've done this because I'm still a virgin, but I can't stop here.

Relying on my instincts, I licked her dripping slit up and down, gulping down the fluids that got into my mouth as I moved. Yumi-san's scent invaded my nose and it was like a drug, intoxicating me that I can't think of anything but pleasing her.

"Hyaaa... T-Tenko-san.... are you licking— uwaaah~!"

After a few moments of licking her entrance, I switched to sucking, placing my lips directly against her sweet honey pot and got to work. I also made sure to swallow every drop of her juices, because I can't let it go to waste.

"It feels good! I-I can feel it! It's so good~!"

I didn't stop there. My hands let go of her thighs and flew up to grope her chest, as I gave each mound a squeeze. My fingers then found her nipples and I tried to pinch both of them, as I'm curious to find out how she would react to it.

"Tenko-san.... Tenko-san...... I— AAAHHHHH!"

Out of nowhere, a torrent of female fluids from Yumi-san's entrance exploded on my face as she screamed, which could only mean one thing.....

She had reached her climax.

Her fountain continued to spray my face with her sweet juices for about ten seconds, before it finally stopped. Within that time, I couldn't do anything but close my eyes and take it head on, because I had no idea what to do. I may have done all these things to her, but I'm still a virgin!

When she was finally done, I sat back up and looked at Yumi-san to see how she's feeling. Her hair was disheveled, her eyes were about to close, and she was taking long and deep breaths.

"......Tenko....san......"

With a tired voice, she closed her eyes and drifted off to sleep.

......I guess that's it then.

Even though I didn't really do much, what happened between us still took a lot out of me. It's not easy to please a girl, especially when I did all of those because I didn't have any choice. I had to lean against the nearby bench and take several deep breaths so I could rest for a bit.

It's still hard to believe that I just had not-sex with a girl, who was also classmate, on my first day here.... argh, I'll think about this later. I have a bigger problem right now!

Snapping out of my thoughts, I used the towel I had in my pocket to wipe my face clean of her fluids, as I snuck a glance at my watch and then the sleeping girl.

That's one problem down, but here comes the bigger one. I have to figure out a way to carry her back, change my uniform, fix her up, and get back to class all within fifteen minutes, otherwise we'll be late and my classmates are gonna wonder where we are.

What should I do.....?
