The Contract

I think it's called a negligee? I'm not really sure, but Kurihara-san was wearing a pretty light pink outfit. It was so thin that her underwear was showing through.

Her breasts really were quite large. Well, considerably smaller compared to Solange-san, but still.

Perhaps noticing my gaze, Kurihara-san quickly covered her chest, her face turning red as she put on a beige cardigan that had been left by her pillow. After buttoning it up to hide her chest, she got out of bed.

The cardigan hid her chest and crotch, but from her thighs down, her legs were still visible through the thin fabric. Somehow, that felt even more indecent.

Do girls really wear such see-through pajamas? Or is Kurihara-san just special?

Kurihara-san moved to the table in the center of the room and sat down primly on one of the floor cushions there.

"P-Please, Katou-kun, have a seat…"

Her voice trembled slightly as she spoke to me.

Following her invitation, I sat down on the floor cushion across the table from her.

Kurihara-san kept her head down and said nothing. Time passed meaninglessly.

Honestly, it was really awkward, but this was actually convenient. I wouldn't have anything to talk about if she tried to make conversation anyway, and more importantly, that would be a hassle. Might as well start the experiment now.

I put my right hand into my pocket and thrust my thumb into the hole of the Parent Peach. A wet, squelchy sensation transmitted through my thumb.

"…!?"

The Peach Butt trembled, and at the same time, Kurihara-san, sitting across from me, also shuddered.

I had been pretty sure before, but this confirmed it. The Peach Butt and the person whose name appeared on it shared sensations.

When I moved my thumb in and out with a squelching motion, the Peach Butt trembled happily and tightened around my finger.

"Nn, kuh, hah… E-Excuse me for a moment!"

Kurihara-san, who had been pressing her hand to her mouth and trembling, stood up and left the room with unsteady steps.

Now that I was alone, I took the Peach Butt out of my pocket. That's when I witnessed something interesting.

The tally marks on the Peach Butt were rapidly increasing on their own, even though I wasn't doing anything. The Peach Butt itself was trembling intensely, and its hole was clenching abnormally tight.

After a while, when about three more tally marks had been added, I heard footsteps in the hallway and put the Peach Butt back in my pocket.

Right after that, the door opened and Kurihara-san came in.

"S-Sorry about that. I just remembered something I needed to do, so I went to see my mother."

I didn't ask for an explanation, but she offered one anyway. Her cheeks were flushed bright red and she was breathing heavily. But somehow, she looked relieved.

"Don't worry about it."

After saying that to Kurihara-san, I thrust my thumb into the Peach Butt's hole in my pocket. Then I mercilessly stirred around the hole, which was even wetter than before.

"Kuh!?"

Kurihara-san, who had her hands on the table and was just about to sit down on the floor cushion, froze in a half-crouch, trembling.

"I-I'm sorry! I just remembered something else I need to do!"

She stopped trying to sit and left the room again.

When I took out the Peach Butt to check, the tally marks were rapidly increasing on their own again.

I see. I think I understand now.

If the Peach Butt and the person whose name appeared on it shared sensations, then the reverse should also be true.

In other words, the state of the person whose name appeared on it would be reflected in the Peach Butt. I was fairly certain of it.

Which meant Kurihara-san was playing with her own hole after leaving the room.

As a test, I thrust three fingers into the Peach Butt's hole and stirred it around mercilessly.

I must have kept at it for about thirty minutes. During that time, Kurihara-san didn't come back.

No, it wasn't that she wasn't coming back—she couldn't. She was probably holed up in the bathroom or something.

Since there was a risk that Kurihara-san might start moving around if I stopped playing with the Peach Butt, I got up from my seat while still playing with it. Then I left the room while suppressing my presence.

As I wandered the hallway, I heard a faint voice. Probably Kurihara-san.

I moved toward the voice and arrived at a door. Probably the bathroom.

I pressed my ear against the door while continuing to play with the Peach Butt. Sure enough, I could hear what sounded like Kurihara-san's voice.

She seemed to be desperately suppressing her voice while breathing heavily.

"It feels so good, it's amazing, more, more, harder…"

It was so quiet I had to concentrate to hear it. But I definitely heard it.

So it does feel good after all. I had a vague sense of what the Peach Butt was feeling, but it wasn't just my imagination.

And this confirmed that Kurihara-san missing school frequently was definitely my fault.

I feel bad about that. From now on, I'll set specific times to play with it.

Besides, I have two other Peach Butts, so Kurihara-san's Peach Butt will get more rest time than before.

I returned to Kurihara-san's room, stopped playing with the Peach Butt, put it back in my pocket, and waited for her to return.

Kurihara-san came back about twenty minutes later.

In the end, I didn't have much of a conversation with Kurihara-san before leaving her house.

Solange-san seemed very disappointed and asked me to stay for dinner, but I declined because it would be a hassle.

They're both pretty to look at, but I don't have anything to talk about with them. Being around them isn't particularly fun—just awkward and tiring.

However, just as I was leaving, Kurihara-san tugged at my sleeve and said, "Let's talk at school sometime, okay?"

Hmm, conversations… We don't have any common topics. And I don't want the girls in class to start paying attention to me.

So I left without answering Kurihara-san's question.

After getting home and eating dinner, I told my mom I was going to study and shut myself in my room.

While eating dinner, I observed my mom. Yeah, my mom and Solange-san are completely different.

Solange-san was really beautiful. And her breasts were so big. Remembering that made me want to use the Peach Butt.

I went to my room and checked on the Peach Butts.

The Baby Peaches had grown a bit, but they were still really small. I couldn't even fit a pen tip in their holes.

Thinking back on it, the Peach Butt probably grew because I kept kneading it.

Maybe the more attention you give a Peach Butt, the bigger it grows.

Since I was feeling aroused anyway, I used Kurihara-san's Peach Butt and came twice while thinking of Solange-san. I felt refreshed afterward, but sorry, Kurihara-san.

After that, I just kept playing with the Baby Peaches.

As I predicted, the more I played with them, the more the Peach Butts grew.

I prioritized playing with Solange-san's Peach Butt. And occasionally I'd play with the flower shop lady's Peach Butt.

As a result, there was a significant difference in their growth. Solange-san's Peach Butt had grown to about the same size as Kurihara-san's. And the flower shop lady's Peach Butt was about two sizes smaller than Solange-san's.

There's a limit to how much attention I can give them all at once. The flower shop lady would have to wait.

Also, when I got aroused, I'd use Kurihara-san's Peach Butt, but otherwise I mostly neglected it. Thanks to that, Kurihara-san stopped missing school.

But Kurihara-san became even more withdrawn and quiet than before.

Maybe my affection for the Peach Butt was being reflected in her? Perhaps I need to give her proper attention from time to time.

Besides, even though I could now use Solange-san's Peach Butt too, Kurihara-san's was still the best in terms of feel and attachment since it was my first.

On days when I used Kurihara-san's Peach Butt, she seemed happy and more energetic.

So affection really was being reflected.

Half a year passed, and we moved up a grade.

Kurihara-san's breasts had been growing steadily too.

Also, I still only had three Peach Butts—the number hadn't increased.

Part of it was that there weren't any girls I was interested in, but I'd also been actively avoiding getting interested in other girls.

Because if I got any more Peach Butts, there was no way I'd be able to manage them all.

Three was plenty. Besides, each of the three had their own personality and were cute in their own way.

Kurihara-san's Peach Butt was easy to use in every way. It was flexible yet had a strong grip, and using hers felt the best.

Solange-san's Peach Butt was a bit loose. Maybe the hole was originally on the larger side. But it had the most intense reactions and was the most entertaining to use. Since the hole was loose, I'd use it when I wanted to take my time enjoying myself.

And the flower shop lady's Peach Butt was the most high-maintenance. It was needy—if I didn't use it, it would immediately start trembling like it was crying. Yet despite all that, it had the worst feel of the three.

Well, they say the more troublesome a child is, the cuter they are, and I did find myself wanting to give it attention.

So it became a sort of rule that I'd usually bring the flower shop lady's Peach Butt to school.

And so, I was living ordinary, uneventful days.

Until that day.

After school, as I was walking down the hallway to head home, I spotted Kurihara-san. She was walking alone in the hallway.

At school, Kurihara-san was always surrounded by lots of girls, but it seemed she commuted to and from school alone. Same as me, actually.

I used to walk to and from school with Tamotsu-kun, but after he stopped talking to me, I ended up alone a lot.

My grades had stabilized at the top of our year. And I was reasonably good at sports too. Once that became well-known, girls started talking to me more often.

Apparently, Tamotsu-kun didn't like that.

It's not like I wanted them to talk to me, and honestly, it was a real nuisance. When people are watching me, I can't freely play with my Peach Butt.

So lately, I couldn't play with the Peach Butt in the classroom anymore. Instead, I started going to the bathroom stalls during breaks to play with it.

It was really annoying.

Anyway, I was curious about Kurihara-san walking alone in the hallway, so I decided to follow her.

Head down, looking lonely, walking with heavy steps—Kurihara-san arrived at the bathroom near the special classrooms.

That area had the science room and chemistry lab lined up, and after school, there weren't many people around. Plus, it was in a different building from where we normally had class, so it was quite a walk.

There were plenty of bathrooms around, so why come all the way out here?

I had been tailing Kurihara-san from a distance, and after she entered the bathroom, I waited a while before approaching. Then I listened carefully.

I couldn't hear anything. Looking around, there was no sign of anyone nearby.

I put my hand in my pocket and touched the Peach Butt.

Damn, I should have brought Kurihara-san's Peach Butt. The one I had with me today was, as usual, the flower shop lady's Peach Butt.

This one was so needy that if I didn't touch it, it would immediately start trembling. Kind of a hassle, but that's what made it cute. Plus, the feel was bad and it had absolutely nothing else going for it, which conversely made me find it endearing.

I waited in front of the bathroom for a while, but Kurihara-san didn't come out.

I could roughly imagine what she was doing. I'd stumbled upon this kind of scene many times before. But doing it after school was strange. It would be safer to just go home.

I looked around again, confirmed no one was there, and crept into the bathroom.

A row of stalls with open doors lined up before me. Only the door to the very last stall was closed. That must be where Kurihara-san was.

Slowly, carefully making no sound, I approached the last stall and listened closely.

"Why? Why? At first, you forced yourself on me even when I hated it, but now that I want it, you won't do anything…"

Kurihara-san's voice echoed through the bathroom. It wasn't the suppressed voice I'd heard before. At this volume, anyone who came in would definitely hear her.

"Are you bored of me? Hey, are you bored of me? You're there, aren't you? Answer me! Touch me like before!"

Breathing heavily, Kurihara-san's voice was anguished. Along with it, I could hear wet, squelching sounds.

It's not that I was bored of her. It's just that the flower shop lady's Peach Butt had been fussy lately, so I'd been doting on that one instead.

In terms of feel, Kurihara-san's Peach Butt was still the best.

"Please! Someone find me! It's so hard! I can't satisfy myself! Someone find me!"

Hearing her voice echoing through the bathroom, I understood why Kurihara-san had come here.

I see. Because I hadn't used Kurihara-san's Peach Butt recently, she'd become frustrated.

So she wanted someone—anyone—to play with her hole, and she was deliberately raising her voice hoping to be found.

But the fact that she chose this deserted bathroom meant she was also afraid of the risks if she was actually discovered.

Well, of course. If word got out that she'd been playing with her hole at school, she wouldn't be able to come to school anymore.

Maybe I should be considerate here and quietly tell someone about Kurihara-san. Tamotsu-kun would probably be thrilled, and maybe he'd stop ignoring me.

But then again, Tamotsu-kun is surprisingly talkative. If he told everyone and Kurihara-san couldn't come to school anymore, I'd feel a bit responsible.

I guess I have no choice. I'll have to handle this myself somehow. Honestly, it's a hassle, but if things go well, maybe she'll let me touch her breasts.

Sighing, I knocked on the door. The instant I did, there was a loud clatter from inside.

She was probably startled. She wanted to be found but also didn't want to be found—those conflicting feelings were at war with each other, so when someone actually found her, she must have been terrified.

Hmm, I have a feeling this is going to be really troublesome.

"Kurihara-san, right? It's me, Katou. Remember when I came to visit you? Anyway, I don't think it's a good idea to be digging at your hole in the school bathroom. But I won't tell anyone, so don't worry."

I figured rather than being overly considerate, just being honest would help Kurihara-san relax. Plus, that way it would seem like I didn't have any ulterior motives.

"N-Katou-kun!? Katou Akiharu-kun from our class!?"

The voice from beyond the door was trembling like she was about to cry.

"Yeah, that's me, Katou-kun. I actually knew for a while that you'd been digging at your hole in the bathroom. But I never told anyone, right? I won't tell anyone from now on either. So I think you should stop doing anything too reckless."

If she got caught and it became a problem, I'd feel a bit bad too. Since it's safe at home, she should just go home and dig there.

After that, silence filled the bathroom for a while.

Kurihara-san is pretty and has big breasts, but this awkward silence is the problem with her. She's cute as a girl, but I don't really find her appealing as a person.

That said, the flower shop lady who chatters on about things I didn't even ask about is also annoying. But somehow I still want to give her attention, so maybe she has a higher favorability rating than Kurihara-san? I don't even understand my own feelings.

Also, Solange-san seems like she'd be troublesome like Kurihara-san, but she's even more beautiful with bigger breasts, so I'm very interested in her. But she's loose and doesn't grip well.

While I was spacing out thinking about such things, Kurihara-san still wasn't responding. I decided to go home and turned to leave.

I'd warned her, so whatever problems Kurihara-san caused from here on out wouldn't be my fault.

Just as I started to walk away, I heard a click, and the door opened slightly.

"Is it just you, Katou-kun?"

I could see a blue eye peering at me through the gap in the door.

Whether anyone else was here—she could easily check that herself. Relying on others isn't a good habit.

"It's just me. If anyone else was here, it would be chaos by now, right? See? So you should just go home for today. I'll keep your secret if you do."

I said that to the blue eye watching me through the gap in the door.

"R-Really? Really truly, no one besides Katou-kun is here?"

Ugh, so annoying. I already told her to check for herself. Seriously, just come out of the stall and go home already.

I'd been thinking maybe I could grope her breasts if things went well, but forget it. I just want to get away from here as fast as possible.

"L-Let me in!"

"Huh? Whoa!"

Suddenly the door swung open violently, and a white hand shot out. That hand grabbed my wrist and forcefully dragged me into the bathroom stall.

Once I was inside, the door slammed shut behind me. Then I heard the lock click.

"I-I can't trust you. I can't trust that you won't tell anyone…"

A trembling voice echoed. When I looked up, Kurihara-san was glaring at me with an intense expression. But her body was shaking.

That aside, I couldn't believe my eyes. Kurihara-san was completely naked. She was only wearing her white indoor shoes and white socks—nothing else.

Hiding her large breasts with her right arm and covering her crotch with her left hand, Kurihara-san was glaring at me like she wanted to kill me, her face red all the way to her ears.

I'd never seen Kurihara-san like this. Also, her breasts looked bigger than when she was wearing clothes.

"T-Take them off!"

"Huh?"

"Katou-kun, take off your pants too!"

What is this person saying? Just because she's naked, why do I have to take off my pants too? This makes no sense.

"No way. Unlike you, Kurihara-san, I don't have a hobby of getting naked at school."

"Ugh."

Kurihara-san's face contorted at my words. Apparently, I'd hit a sore spot.

Still, not giving up, Kurihara-san hardened her expression and took a step forward.

"I'll tell."

"Tell what?"

"I-I'll tell the teacher that Katou-kun attacked me in the bathroom."

"Excuse me?"

What is wrong with this person? She stripped naked on her own, and now she's threatening me. What kind of upbringing did she have? I'd like to see her parents' faces.

Oh wait, I have seen her parent. She was beautiful.

"I-I can't trust you. S-So we need to share a secret. If either of us reveals the secret, we'll both be ruined. See? Then you can trust me, right?"

Kurihara-san smiled smugly while trembling. What do you mean, "See?" If the secret got out and we were both ruined, wouldn't I be the only one losing here? Because I haven't done anything wrong.

"No way. Go ahead and say whatever you want. If I took off my pants here, you'd actually have something on me, so I'm definitely not doing that."

"Uuu…"

At my answer, Kurihara-san hung her head and tears started dripping down.

Crying won't change my answer. Right now, she doesn't have anything on me—she's just threatening to lie and frame me. If I actually gave her real leverage, I'd have to do whatever she said.

There's no way I'd agree to conditions that only disadvantage me.

"Th-Then, what do I have to do for you to keep my secret?"

"Huh? I already said I won't tell anyone, didn't I?"

"… I can't believe that."

"Ugh, this is so annoying."

Kurihara-san was being so troublesome that I accidentally said that out loud.

Forget it, I'm going home. I got to see her real breasts even though she was covering them with her arms, so I should be satisfied with that. I'll just leave Kurihara-san alone.

When I approached the door to leave the stall, Kurihara-san jumped to block it, spreading her arms wide.

Oh, her breasts were in full view now. Plus, they were jiggling from her jump.

"I-I won't let you get away! I'll scream! I'll scream for help! You'd be in trouble if I did, wouldn't you!?"

Eyes wide, Kurihara-san raised her voice. Her eyes had completely lost their composure. And she was already practically screaming.

This is bad. She's not in a state where words will get through to her. Right now, there's really no telling what Kurihara-san might do.

They say the quiet ones are the most dangerous when they snap. It's really true.

What should I do? Getting actual leverage held over me by someone this dangerous would be risky. But man, those are some nice breasts. White, big, and they look so soft. And every time Kurihara-san moves, they jiggle. They're like pudding.

And the tips are pink, standing up pertly. I'd really like to touch them if I could.

But still, I don't want to give in to momentary desire and regret it later. I have the Peach Butts, and I don't want to do anything indecent with Kurihara-san badly enough to take on risks.

"I still don't want to. Move out of the way, I'm going home."

"No! I can't back down either!"

"If you keep throwing a tantrum, I'll tell everyone everything. Whatever happens after that, it'll be better than having you hold something over me. Come on, move aside. If you do, I'll keep your secret."

I stared straight at Kurihara-san as I said that, and her expression crumpled with sadness.

It seemed I had won. Well, of course. What I said was an irrefutable argument.

Of course, the one who caused Kurihara-san to become like this was me.

"… Please. I'm begging you. I'll tell you the truth, so… please don't leave."

Tears spilled from Kurihara-san's blue eyes as she collapsed on the spot, falling to her knees and clinging to my pants.

"I lied about wanting to share secrets. You said you've known what I was doing for a while, Katou-kun. I thought if it was you, you might keep my secret, so that's why I threatened you…"

Her voice came out in whispers, weak and trembling.

"It's so hard. I can't satisfy myself. I can't resist wanting someone to do it for me. But I'm terrified of someone finding out…"

I understood what Kurihara-san was trying to say. In fact, that was probably what she was after from the start when she dragged me into the stall, and that's why she threatened me.

And now she was resorting to a tearful appeal. She really was a troublesome person. I could see that getting involved with her would only bring problems.

"I don't have any friends. Not a single one. Everyone hates me. Because of my personality, I know everyone secretly thinks I'm annoying. I've never even had visitors—well, no wait, Katou-kun was the first person to come to my house. Katou-kun is… my only friend."

I felt a chill run down my spine and tried to back away. But she was clinging to my leg, so I couldn't move.

What do I do? This person might be even more dangerous than I thought. Just a moment ago, she'd been crying and clinging to me, but now she was looking up at me with a disturbingly eerie smile.

Nothing I said would probably get through to her now. No matter how logical my argument, she wouldn't accept it.

"I-I would never do anything to trouble you, Katou-kun. I'll do anything you tell me. I'll do anything for you. So please… use me…"

Saying that, she pressed her breasts against my leg. Then she started unzipping my pants without permission.

She said she'd never do anything to trouble me, but she's troubling me right now.

Should I call for help? But if someone saw the current situation, honestly, it would turn out exactly as Kurihara-san said.

I was already at a disadvantage the moment she dragged me into the stall.

Still wearing that eerie smile, Kurihara-san took my penis out through the open zipper, rubbed her cheek against it, and then opened her mouth and took it in.

"Ugh."

I couldn't help letting out a sound at the sudden hot, slippery sensation.

It felt good. This felt incredibly good.

Looking down, I could see Kurihara-san kneeling on the floor, her chest exposed and her breasts swaying.

As my penis grew bigger and bigger, I stopped thinking.

"The contract… is sealed, right?"

Kurihara-san let my penis slip out with a slurp, looked up at me, and said that with a sweet smile.

Well, yeah, this turned out to be a pain, but she's cute and her breasts are big, and it feels good, so whatever.
