Track 7: Will I be able to pee properly? (2/2)

“IYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!”

Mutsumi let out a scream loud enough to shake the house and then ran from the room. Even though it was me, whose diaper-wearing appearance was seen by a family member, who wanted to disappear. I have to do something to fix this misunderstanding, or else I will be thought of as a perverted older sister who likes being incontinent into diapers!

“W-Wait!”

There’s no way I could let her escape. It was no longer at a stage where I could do something even if I caught her, but right now in her panicked state, Mutsumi probably wasn’t ready to report me yet. I went out into the corridor and immediately jumped towards Mutsumi, and then tightly held her from behind.

“HIIIIiihhh!! N-Nooo, leh mo, mmm———mm————!!”

“Please! Listen to what I have to say!”

I put one hand over Mutsumi’s mouth as she made an expression of fear that seemed to come from the bottom of her heart. I tried to persuade her, but Mutsumi struggled as if she seriously sensed a danger to her life.

Well, it’s true that if I were in her position, it would be quite a frightening situation. She was being held in a full nelson by someone wearing a diaper filled with crap that was letting off a terrible stench. It would be stranger if she wasn’t screaming.

“Mm————mm———–!! Mm———-……..”

“First we need to calm down and talk……wait, huh?”

Just when I thought she had become docile, Mutsumi’s head suddenly dropped to the side like a puppet whose strings were cut and she stopped moving. It seemed that the chaos and fear were so much that she fainted. It’s true that I was entirely at fault, but for her to faint because of her own sister was quite a shock.

“For now, I’m saved……”

I crumbled on the spot in exhaustion. But this wasn’t the end. An unthinkable weakness was grasped by this younger sister of mine. I have to do something to muzzle her. But just how……

“……oh! I know!”

Seeing the music player that had been left on my bed, a light bulb jumped out on top of my head.

◆◆◆

“With this, it’s done……!”

Looking down on Mutsumi who was lying down on her own bed, I wiped away the sweat on my forehead. Mutsumi was stark naked. She was only wearing a diaper on her bottom. She was just like me. I put the music player’s earphones into her ears and had her listen to the diaper voice recording from earlier.

“I have to obtain material so that I can negotiate with this little sister of mine on the same level.”

Right, if she has a hold on my weakness, then all I have to do is drag Mutsumi down to the same level as me. If she experiences the hypnotic voice in practice, then I’m sure she’ll believe in what I have to say, so it’s taking down two birds with one stone. All that’s left is to pray that Mutsumi is able to properly fall into a hypnotic state.

I have to resolve all of this before our parents return home. As it was a race against time, I still hadn’t changed either. If it fails, then Mutsumi may wake up, so I can’t let my eyes off of her until I’ve confirmed that she’s completely fallen.

“………………..ah………………uwah……………..”

As Mutsumi opened her eyes faintly, at times she would react to the recording and let out small moans. Perhaps she thought that she was dreaming, or her consciousness was still faint, but it seemed like she was obediently listening to the voice recording.

“I suppose I’ll take a picture as evidence while she’s still docile.”

In order to prepare some materials to keep Mutsumi’s mouth shut, I readied my smartphone’s camera.

Hmmm, maybe it’d be better to do it so that the diaper can be seen a bit better. Open up her legs……alright. That’s right, if I’m gonna do it, might as well make it more unsightly. I have to make her face the same level of embarrassment that I did. Like this…….completely opening up her crotch……while I’m at it, both her hands as well……put the back of her hands on her hips……so it looks like she’s going “Ahem!” proudly……*rummaging sound*……

……done! My younger sister in a bowlegged “Ahem!” pose while wearing diapers!

Click! Great! Click! Click!

No matter what age they are, all girls love to play with dolls. If the hypnosis from the recording goes well, then she shouldn’t be able to move her body of her own accord, so I’m sure she’ll be quite surprised when she wakes up.

Just as I was thinking that, Mutsumi started to wake up. Based on the time, it seemed that the hypnotic induction had just about ended, and the voice had woken her up.

“……uu…….uunn……Onee-chan……I……?”

“G-Good morning~”

I timidly called out to her. If it went well then she should be in a state in which she’ll be unable to defy the voice but……

“……wait, EHHHHHHH!? What’s with this appearance!? ……h-huh……? No way…what…this…I can’t…move my body……!”

Alright, it succeeded! As expected of my little sister. Though I don’t really understand what exactly is ‘expected’. In any case, with this Mutsumi has been rendered powerless.

“What is this!? Don’t think I’ll let you off easy for doing something like this!”

“*cackle* Even if you threaten me, I’m not scared while you’re wearing a dia~per.”

I took a picture of Mutsumi as she glared at me menacingly. I managed to capture a good expression. Now then, since she’s woken up, it should mean that her lower half should be experiencing the intense need to pee and poo.

“…….i-i-i-if you stop this voice recording right now, I-I’ll s-specially f-forgive you-”

“Oh oh~? Why are you making such a miserable expression~? Could it beeee that you want to go pee peee?”

I grinned broadly while looking down at Mutsumi, whose voice was clearly trembling. Somehow she appeared very cute, and I started to have fun. To think that the day would come where my more reliable little sister would beg me in such an appearance and inferior position.

“J-Just what is your goal? I ran away earlier, but I d-definitely won’t tell anyone that Onee-chan has those sorts of hobbies, so-”

“……it’s already too late, Mutsumi……after this, I will have Mutsumi experience the same fate as myself……since you’ve learned my secret…….there’s no way that I can allow you to return safely……”

Just what sorts of hobbies do you mean by ‘those sorts of hobbies’? Though she was saying that, there’s no way that this little sister of mine wouldn’t report this to Mother. I’ll need to thoroughly punish her. I must have Mutsumi taste the dreadfulness of the hypnotic voice.

“AAAahh, Onee-cha-, nn, really-, right now it’s terrible-, hurry up and stop the recordingg, hiiu-, t-the c-countdown is–”

Ahh, so the incontinence countdown has started? Her face has become bright red, and her body is trembling. *snap*.

“Onee-chan isn’t doing this as a game. I’m serious. It’s okay, I’m sure that Mutsumi will also understand it soon enough.”

“It’s fine if I don’tttt, ahi-, O-Onee-chan, something’s weird, there’s no way there’s something like hypnosis, hiiun-”

It’ll be soon, huh. When the count reaches zero, then she’ll lose all ability to endure it. Now then, first let’s have her wet that diaper with her urine.

“If you’re going to say that much, then you won’t pee into the diaper, right~? Since Mutsumi’s smart, you’ll be able to properly endure it, right~?”

“O-Of coursh, I-I won’t- ah♥ Nonono, that’s-, no-, ny-, ny-,ny-♥ nyoo, AH——–…….nnhaAAAAAaaaaaAAAaaahh……………..♥”

Fwshhhhhhhhhhhh……..chororororororororo.

I heard the violent sound of urine being released into the diaper.

Ahh~ah, so she couldn’t endure it. No, but, for that straight-laced little sister of mine to pee herself, the hypnotic voice truly is terrifying.

“Nyo wayyyyy……..♥ My pee is kyuming outttt………♥”

Mutsumi appeared to be feeling good as she made a bewitched expression. Seeing that, I felt a shiver run up my spine. As she displayed her appearance while urinating into the diaper, her nipples protruded as she stiffened into a pose that looked as though she were proudly thrusting her chest out. What is this cute animal?

“Haa…….aahh……..uuu…….this is…….the worst…….”

A weird switch had completely flipped on. I wanted to see more of Mutsumi’s cute expressions. My little sister always played cool. I wanted to see that face of hers warped with shame. I stroked my hand along the face of my little sister who was still immersed in the reverberations of her incontinence, and whispered loud enough so that she could hear me past the earbuds.

“You peed into the diaper, didn’t you? Then next let’s have you poop, shall we? Mutsumi doesn’t need to think of anything, and just needs to listen to that voice, okay?”

“Haa……haa……w-what the heck are you saying!? Just hurry up and remove the earbuds, or else, I’ll-”

Around the time that the dreadfulness of the hypnotic voice had begun to sink in, it appeared that she was given the explanation for the next countdown. Though she pretended to talk tough, her face had gone completely pale. The second countdown. It was the hypnosis that sent your self-control and intelligence down to zero.

“Fall to the same level as me, kay, Mutsumi? Become stupid from the countdown, so that we can become sisters who both pooped and peed into diapers together, alright?”

“No……! I don’t want that! Please, stop the recording, the countdown’s already started-…….!”

If that’s the case, then it’s already too late. I can’t wait. Mutsumi’s gonna be the same as me, huh. My little sister really is too adorable. Since she’s so adorable, I’m gonna pet her head.

“Aheeeeeee……♥ Ah, dyon’t pet my heaaaaad……♥ I’ll willy, willy bekyum a babyyyyy♥ Fuheeeeeee…….♥”

“It’s fine if you become a baby. Your mind will steadily melt away, and you’ll become an empty-headed baby that can’t think of anything, ‘kay~”

Pet pet. Pet pet. Even though she was playing it tough only moments earlier, as the count continues her face slowly started to loosen up. Thinking about it, this is the first time I’ve seen someone else go under, but it’s interesting to see the slight differences from my own experience.

“Onee-chan you idyott♥ Moryonn♥ Hyurri up and sabe mee♥ Ahiii♥ I’m, I’m bekyuming weirdddd♥ Ah, ah, ahh♥ Nnheeeeeeeh♥”

“Then become weird? Let your head go funny, and let Mutsumi’s sti~nky poopy go allllll over the diaper, ne?”

BUBIBIBIBIBI BUSHuuUUU

When I whispered that to her, Mutsumi made a face of ecstasy as she let out a cute fart.

“Ahaha, oh Mutsumi, responding with a fart is rude.”

“NnaaaAaaaa…….♥ Wet me gyooooo♥ Ish gunna kyum outtt♥ Poopyyy♥ Poopy is gunna kyum outt……..♥ NnaaAAAAaaaaa…….♥ Muchumi kyan poopy on her ownn♥ Am I smart~?♥”

Seeing her innocent and slovenly face, it felt like my chest tightened. At this time, I was probably the epitome of a pervert, with bloodshot eyes as I watched while panting roughly and licking my lips.

“You are really, really smart~. Poopying into your diaper, feels realllly good, doesn’t it~? Let’s let lots and lots of poopy out, ne~?”

“Auu————–♥ Ah ah♥ Uhh———————-♥ Oahh♥ Nn nn nnn♥ OH——————♥♥”

Ahh~, she broke. She’s making a wonderful face while straining. I wonder if her head’s just filled with pooping right now?

And then in the next instant, it felt like I also heard the voice say “Zero”.

“NnAAaaaaAAAAAAaaaaahhhhhh♥♥ HiguuUUUUUUuuUUUuuuu♥♥ OH OH OH♥ NNNNNNNNNNNNNN♥♥”

ZWSHHHHHHHHHHH BUOFF BFFFFFFTTTTTTT

It was a scream that was no less than my own. A distinct stench once again enveloped the room. Mutsumi’s diaper swelled up. I was so excited by the scene unfolding in front of my eyes that I came a little.

For the finale, I took a picture of my younger sister as she lay bowlegged after having a magnificent bowel movement.

“Haa……haa…….haa……ah…….♥ Haeeaaahhh…….♥”

Afterwards, I gazed at my younger sister as she trembled while maintaining that stance with an ecstatic expression.

◆◆◆

“I am truly sorry…….!”

I was currently kowtowing on the ground with my head against the floor, still in my thoroughly soiled diaper. Looking down on me with an imposing stance with a similarly full diaper was my younger sister Mutsumi. It seems that I got a bit too carried away.

“To think that Onee-chan had gotten addicted into some nonsense like this.”

“No no, like I said before, it’s not that I’ve gotten addicted, I’m just training. And also, didn’t Mutsumi also end up like me in the end too?”

“Uguh……th-that’s…….”

Having that pointed out, Mutsumi’s face turned bright red as she fell speechless. Being able to turn the tables like this really helped. If the hypnosis had failed and the only one wearing diapers right now was me, then in the future Mutsumi would have probably been scrunching her nose while looking at me like I was trash.

“I-I-I-I-In any case! You’re forbidden from speaking about what happened today to anyone else! If you delete those pictures in front of me then I’ll keep quiet too!”

“……heh~……”

I reluctantly accepted that demand. Even though I went through the trouble to take such cute pictures. Well, at least I’ve achieved my initial goal. It’s gone from a situation where my weakness was grasped one-sidedly, to one where the two of us have secrets we need to deal with. I somehow managed to avoid having my life come to an end.

After securely stuffing the diapers into a bag, I decided to take out the trash first thing in the morning the next day. For the first time in several years, Mutsumi and I took a bath and washed our bodies together. We did so without letting our eyes meet once, both hanging our heads in shame.
