Chapter 104 : Impending Madness (R-18)

"welcome to Japan. It's great that you're here now.~~"

I was singing alone, enjoying myself and the luxurious sound quality of the BOSE speakers, when the door to the room opened with a click.

"Horagasaki-kun... Are you here?"

But I was too absorbed in my singing to notice.

"Thank you from the bottom of my heart for this extraordinary fate…~~"

"Horagasaki-kun?"

I felt a tap on my shoulder, and when I turned around, there stood Matsushita Chiaki, from my class and my source of fear.

"M-Matsushita... why are you here?"

"I rang the bell and called, but there was no answer. When I opened the door, it was unlocked, so I thought you might be in."

Matsushita entered my room without a second thought, and I couldn't help but feel a bit of respect for her audacity.

"So, why are you here?"

Given what happened last time, I was somewhat wary of Matsushita. Even though nothing major happened before, if given the chance, I might have ended up being her obedient puppy.

"Eh? Am I not allowed to come? Why? Do you hate me? I'll apologize for what happened before, but it's weird to start hating me because of that, right? That's not fair."

Here it comes, Yandere Chiaki.

"It's not that I hate you, but it's a bit too much. I can't handle stuff like that."

Matsushita seemed a bit surprised by my blunt response, and she started to look a little dejected. It seemed she was somewhat reflecting on her actions.

But then I noticed something. There was something like a strange white powder peeking out from her pocket. Trying not to be obvious, I squinted and glared at Matsushita while looking at her pocket.

"Hey, what's that?"

Matsushita looked at me blankly, not changing her expression, and said, "This? It's a headache medicine I bought earlier."

"Why are you carrying headache medicine?"

"I get sick quite often... so I always have it with me. Didn't you notice?"

She looked at me sadly. I felt guilty for being so suspicious.

"Sorry about that... I'm going to get a drink. Make yourself comfortable."

As I left, I discreetly placed a bugging device under the table.

Once I was outside, I couldn't hear the living room noises. Pretending to put on my AirPods, I connected to the earpiece and waited outside, listening.

Rustle, rustle.

I heard the sound of something being rummaged through. As I listened, tilting my head...

"...Horagasaki-kun's scent, it smells so good... It feels like I'm wrapped in him. Hehe, you're all mine now."

Cold sweat ran down my back. I didn't know exactly what she was doing, but it was clear she was doing something weird with my stuff.

"I should prepare some tea for when he gets back. He must be tired, and I feel bad about what I did."

I was a bit surprised by her unexpected thoughtfulness. If nothing strange happened, it might be fine...

"Hehe, there's no way it's just headache medicine. I'll make Horagasaki-kun sleep and make him mine. Wait for me, my prince. I'll spoil you and train you so you can only see me."

I take back what I said. I knew it wasn't just headache medicine. I'm glad I took precautions early.

"I wonder when he'll come back..."

Matsushita couldn't wait for her excitement. But she didn't realize that I could hear everything she was planning.

"...Scary."

Gathering my courage, I returned to the room. As I opened the door, Matsushita greeted me with a feigned innocent expression, sipping tea.

"That was quick?"

"I made some tea. Please have some if you'd like."

"Thanks, I was just thinking I wanted some tea."

I pretended to drink the tea with sleeping pills. I glanced at Matsushita and saw her smirk slightly. Too bad for her. This is where it ends for you.

"Ah, I'm starting to feel sleepy."

"Getting sleepy? Should we call it a day?"

"Yeah, sorry Matsushita. Come again sometime?"

"Sure, no problem. Goodnight."

Pretending to be sleepy, I staggered to the bed and lay down. I could feel Matsushita's intense gaze on my back, but I closed my eyes and pretended to sleep.

"...Is he asleep?"

"..."

"Hehe, Horagasaki-kun is surprisingly easy. He's only good at academics and sports, but his perceptiveness is low. This could be useful."

Her underestimation made me a bit angry. I have my pride as a man too.

"First, let's tie him up..."

I heard a clicking sound and realized she had taken out handcuffs from her bag. I felt the cold metal on my left wrist and then my right. At that moment, I grabbed Matsushita's arm and cuffed her right wrist instead.

"...Huh?"

Matsushita was bewildered, not expecting me to be awake. She panicked, trying to free herself from the cuffs. I sat up and revealed everything.

"Hey, you seem to be having a lot of fun, but what were you planning?"

"Uh... um..."

Glaring at her, I smirked. Matsushita, trembling, tried to back away.

"Something about 'training'?"

"Why... how did you know...?"

"Oh well. These cuffs are annoying."

Using all my strength, I freed myself from the handcuffs.

"How... how did you get them off?"

"Huh? Were you surprised it missed?"

"Uh... no, um, that's..."

Seeing Matsushita's shock, switching her gaze between me and the cuffs, I continued.

"Headache medicine, huh? Almost got tricked into drinking sleeping pills."

"You noticed...?"

"It would be stupid not to. Acting is quite a hassle, you know."

Realizing everything had been exposed, Matsushita looked devastated.

"I'm sorry... I didn't mean..."

"Yes, you did. Wasn't I supposed to be 'easy to fool'?"

"No... that's not..."

"Yeah, yeah, whatever."

I cuffed her left wrist to immobilize her. Matsushita glared at me, but I was the one who had the right to be angry.

"Hey, Horagasaki-kun, there are things you can and can't do, right? Can you take these off?"

"What are you saying? You've got some nerve."

Seeing me genuinely angry, Matsushita's defiance turned to fear.

"Are you mad...?"

"Take it as you like, but you're way too full of yourself, Chiaki-chan."

When I looked at Matsushita with an intimidating expression, she must have sensed danger, because she ran out of the bedroom and went into an empty room, locked the door, and tried to hide from me, but I thought she was a little too arrogant, so I decided to scare her. Matsushita-chan, you're being a little too arrogant.

(Why, why, why! Why do I have to run! But what should I do? I've made him mad! Scary, scary, scary... I have to run, if I get caught, I'm done for... My instincts are telling me, if I get caught, I'll die.)

I rattled the doorknob of the empty room where she was hiding.

"Chiaki~? Hey, Chiaki~ open up~?"

She didn't show any signs of opening, so I brought a chair from the living room and started banging it against the door. Matsushita must be feeling immense fear right now.

"Don't run away, Chiaki~?"

Bang! Crash!

"No, no... I'm scared...!"

"Hey, come out~!"

Bang! Boom!

"Hah, hah, no, help!"

"Open up~?"

With an overwhelmingly psychopathic performance, I hope Matsushita will calm down a bit now.

This is going to cost for repairs... but at most, around 100,000 yen. It can't be helped.

Saying this, I smashed the door's glass panel and peered inside. In the corner of the room, Matsushita was cowering, trembling in fear.

"Oh, there you are. Don't hide in a place like that~"

"No, no! Don't come here..."

I unlocked the door from the inside and approached Matsushita, who had no escape and was trembling, tearful. As I slowly got closer and slammed my hand on the wall, Matsushita flinched, closing her eyes in fear, then opened them cautiously.

"Hey, why did you run away?"

"Eek...!"

Maybe I scared her too much; her eyes are clearly looking at me differently. I might have overdone it a bit... But I was scared of her too, so it's payback, right?

"Ah, then, how about we have some fun now?"

"No, no... Don't come closer."

"Why not? Didn't you drug me because you liked me and wanted to do it?"

Grabbing Matsushita's cheek roughly, I made her tearful eyes meet mine.

"No... I don't want to be with the current Horagasaki-kun!"

"What? Chiaki, don't mess with me, okay?"

I picked up the chair I had placed on the floor earlier and slammed it down hard, causing Matsushita to tremble and start crying.

"I'm sorry, I'm sorry... please stop..."

"Don't think crying will solve anything, Chiaki."

I forcefully unbuttoned her shirt, revealing her chest, making it look like a real rape scene from a drama.

"No...!"

Matsushita tried to cover herself, hugging her exposed chest.

"Shut up and do what i say."

"Let go...!"

As she tried to resist by kicking, I grabbed her ankle with my right hand. Matsushita's legs were thin... she still had a great body.

"Don't struggle, it'll be over soon. Okay?"

I spoke gently, but with a glare, and forcefully kissed her as she tried to avoid eye contact.

"Mmm... smooch... slurp..."

"Suck... slurp... slurp... puh! Stop it, Horagasaki-kun... what's happened to you...?"

"Huh? You're not excited about kissing me? That's kind of disappointing. I don't need you anymore. I'm fine with other people."

Even though it was an act, saying such mean things hurt my heart... Honestly, I really like Matsushita and don't want to let her go. But this punishment brought out strange, unintentional statements.

"...It's not like that, Horagasaki-kun!"

"Huh? What?"

"Please... don't abandon me..."

Crying, Matsushita clung to my leg, desperately showing her dependency on me. But in reality, I had no intention of abandoning her, but continuing like this wasn't good for Matsushita either.

"I'm not going to abandon you. What? Do you want me?"

"I want you... I want you to be mine alone."

"Don't mess with me; it's the opposite, isn't it? You're mine alone. I like to dominate, but I hate being controlled."

While holding Matsushita, I said this.

"...Horagasaki-kun, could it be..."

"Ah. You got it? From now on, you're my pet."

However, Matsushita didn't seem satisfied and seemed uneasy unless she was the one in control.

"Not satisfied with my power?"

"It's not that... but Horagasaki-kun, I want you to be mine alone!"

Expressing her true feelings strongly, it seemed she didn't like me getting along with others and wanted to have me under her control.

"Just so you know from the start, I'm not anyone's."

"..."

"Do you understand that? Now Jin-kun's fun time is about to begin.

"...Huh?"

I placed my hand between her legs, tracing the cleavage visible through her torn clothes, and lowered her bra, revealing her pink areolas.

"No, stop...♡"

"What? Are you feeling it?"

As I massaged her entire breast and pinched her nipple, Matsushita started to moan lasciviously, and her legs, which had been kicking earlier, began to spread open, revealing her promiscuous nature.

"Your panties are soaked. Were you this wet?"

"No, stop... don't look♡"

"What? Say 'please look' you masochistic slut. Otherwise, you wouldn't spread your legs like this, right?"

"No, that's not it... this is...!"

"This is what? Speak up."

As I teased and bullied her, Matsushita was at a loss for words. As she said nothing, I got a bit annoyed and pinched her nipple harder.

"Ahhhh~♡"

"Hahaha, your pussy is getting super wet."

The stain spread rapidly, soaking her light blue underwear. If she gets this excited just from her chest, what would happen if I penetrated her? I immediately pulled down her panties and inserted my finger deeply.

"Noooo~♡"

"Wow, you're really wet. How much have you been waiting to do this? You're such a slut."

"Don't say that~♡"

I stirred my finger inside her vagina and increased the pace.

"Nooo~♡ That spot is weak♡"

"Haha, you're saying that yourself? Then I'll do it more."

Focusing on her weak spot, I moved my finger vigorously, and as Matsushita began to moan and try to close her spread legs, I forcibly held them open.

"Don't close them, idiot. Endure it~?"

"No, stop, noooo~ I'm gonna cum~!"

"Go on, cum."

"I-I'm cumming!"

"Ah!"

At that moment, Matsushita's whole body trembled as she lost strength, and she squirted an incredible amount, probably about 3 meters.

"Hahaha, you're such a pervert. If you're this wet, it'll go in easily."

I pulled out my erect penis from my pants and, forcing Matsushita's legs open like a frog, rubbed it against her entrance.

"Wait... don't put it in yet..."

"Why should you decide that? You want to feel good, right?"

Ignoring her words, I thrust it in deeply.

Since she was wet and tight, it didn't go in all at once, but with obscene sounds, it slowly slid in.

"Wait~♡ Stop~♡ I just came~♡ Pull it out~♡"

"I'm not pulling out, idiot!"

My cock invaded her vagina step by step, from the head to the middle, from the middle to the very base.

"So tight...! But, I'm not letting you cum yet."

"No~♡ You say that, but I'm going to cum~!"

"Listen to me, don't cum. Got it?"

"Ah~♡ Ah~♡ No~ I'm gonna cum~♡"

With Matsushita's intense moans, the room echoed with the loud slapping sounds of our bodies colliding.

"I'm cumming~♡"

As she said that, I pulled out my penis from her vagina.

"...Huh, why..."

Looking unsatisfied and craving more, she glanced at my lower body with a forlorn expression.

"What? Why are you looking at me like that? Didn't I tell you not to cum?"

"No, let me cum! Why are you being so mean!"

"It's my mood, okay? Why are you acting so high and mighty?"

"Ah... I'm sorry..."

Matsushita sat on the floor in a posture known as "girl's sitting," while I sat on the chair, crossing my legs.

Taking the opportunity, I switched places with Matsushita, who was handcuffed, making her sit on the chair while I sat on the floor with my back against the wall. I left the room and came back with a rope, tying her to the chair in an indecent, spread-legged position.

"No, wait... Horagasaki-kun"

"Huh? What?"

"Is this...?"

Realizing the situation, Matsushita's eyes widened in fear as she was tied to the chair with her hands raised in a "banzai" position, legs spread wide, looking like an AV scene.

"Well then. I brought some toys."

With a sinister grin, I took out a vibrating rotor, anal beads, a textured piston vibe, and a regular wand, ready to break her spirit.

"No... I don't want this."

"It's okay, you can handle it."

I was calm in front of Matsushita who was anxious.

I turned on the electric massager to rub her nipples .

**Viiiin**

"*Ugh!*"

"Oh, it moved. So, what we're going to do now is the 'Endure until you climax' competition, Chiaki version! Clap clap!"

"No, no way..."

"Well, you get it from the explanation, right? Let's get started!"

Matsushita is completely exposed, showing her vagina and anus. First, to commemorate, anal beads are inserted into her anus.

"*Ugh, no, aaah, aaahh♡*"

The first bead goes deep inside. Next, a piston-type bumpy vibrator is inserted into her vagina without turning it on.

"*Wait, no, that's not okay... Aaah, aaahhh♡ Nooo, it's grinding my pussy♡*"

Well, of course, it's bumpy. And finally, there's the rotor-type vibrator. While enjoying Matsushita's situation, it's vibrated around her wet clitoris.

"*Aaahhh♡ Something like this, I'm going to cum♡*"

It's just the beginning, and the piston vibrator isn't even turned on yet, so it'll be interesting to see what happens when it is.

"Alright, let's start. If you can endure for 30 minutes, I'll let you go."

Setting the timer on my phone for 30 minutes, I press the start button. At the same time, the piston vibrator inserted in her vagina and the rotor vibrator both start up.

*Whirr whirr whirr*

*Buzzzzz*

"*Nooo♡ Haa, haa♡ Aaahhh♡*"

The piston vibrator is raging inside her vagina, and I'm enjoying the rotor vibrator on her clitoris. Of course, keeping the power on continuously isn't fun, so I turn it on and off repeatedly to make her cum on purpose.

"*No♡ No♡ I can't take it anymore, I'm going to cum!!!♡*"

In a minute and a half, Matsushita climaxes, the piston vibrator spewing out from her vagina along with her squirt, and she squirts even more from the rotor vibrator.

"Hey, that's too fast. You still have 29 minutes left."

"Please... I can't endure it..."

Breathing heavily, Matsushita pleads for forgiveness with a sweet breath and a red face. Seeing her like this, my mischievousness grows.

"Nope, you failed, so we're doing it until you clear it. Ready for round two!"

Repeating the same process again and again. For Matsushita, it must be hell, but for me, it's the best pastime. She keeps climaxing over and over until finally, she seems to have fainted from the pleasure.

"Hey, wake up. We're not done yet."

I pat her cheeks, but Matsushita doesn't wake up. Her heart is still beating, so I'm relieved but also a bit worried. Then, she slowly opens her eyes.

"Are you awake?"

"Hougasaki-kun... I'm at my limit..."

"Nope."

With a smile, I politely refuse. Thinking she's awake, I start what must be the 6th round.

"*Aaahhh♡ No, it's no good!!!♡♡♡*"

On the 6th round, Matsushita finally urinates. I might have overdone it a bit.

"*Sob... I'm sorry... I won't act cocky anymore... Please forgive me...*"

Crying and reflecting on her actions, Matsushita looks at me. Damn, I might be crazy, but seeing a crying beautiful girl excites me... Matsushita usually acts elegant and high-class, but seeing her like this, so erotic and submissive, is such a contrast that it turns me on even more.

"Alright, alright, don't cry. We'll stop now."

"Really...?"

Wow, she's so cute... I'm seriously falling for her.

"Really."

"You won't be mean anymore?..."

"That depends on you."

I respond firmly. Despite her anxiety, Matsushita keeps apologizing.

"Then, put that big cock in me... and give me a lot..."

"...Got it."

It seems she wanted my dick more than the vibrator play. The stress of being made to cum with strange objects must have been building up.

After releasing her restraints and handcuffs, Matsushita urges me to sit on a chair. She starts to straddle me with a seductive look.

"Alright... Let's have sex?"

"You've been waiting for this?"

"Yeah... I couldn't think of anything but your cock, Horagasaki-kun... So, let's do it?"

As she says this, we start having sex in the face-to-face position. My dick slides perfectly into her vagina, going deep into her wet pussy.

"*Aaahhhh♡ It's here♡♡*"

"The tightness... it's amazing..."

Matsushita starts moving her hips up and down at an incredibly fast pace. My penis feels so good, rubbing against her vaginal walls, making obscene sounds.

"*Aahh♡ Aaahhh♡ This feels so good♡*"

Matsushita is incredibly lewd. Honestly, I'm the one who's about to cum. Her pleasant scent and the feeling of her breasts are the best.

"It's coming..."

"*Aaah♡ Haa, haa♡ Give it to me♡ Pour it all inside♡*"

My penis starts twitching uncontrollably and finally shoots a huge load of semen inside her vagina.

"*Aaahhhh♡ I'm cumming♡♡♡*"

I've perfectly creampied her. Matsushita arches her body and makes a lewd face with her tongue out. But this isn't the end, don't underestimate my libido.

"Matsushita, lie down there."

"*Ugh... Huh?♡*"

"Lie down."

"Y-yes...♡"

Obediently, Matsushita lies down on the floor face down. I straddle her, spreading her legs a bit more, and insert my penis into her vagina from behind.

"*Ahh, nooo♡ It's too sensitive right now♡*"

"You're still accepting it despite saying that."

My penis slides deep inside her vagina, moving my hips for more pleasure.

"*No♡ No♡ It's too much, I'm going to cum♡*"

"*Ah, it feels so good...*"

Increasing the pace, I feel an incredible sense of pleasure.

"*Ahhhh♡ Aaahhh♡ I'm cumming♡♡♡*"

"*Ugh...*"

*Splurt, splurt, splurt*

I shoot another huge load inside her vagina. It's amazing. When I look at Matsushita, her pussy is dripping with a mix of her love juices and my semen.

"Does it feel good?"

Whispering in her ear, Matsushita nods with messy hair, further exciting me.

"I can't live without you, Horagasaki-kun♡ From now on, please take good care of me?"

She spreads her legs and opens her pussy wide, saying "Come more" to break my rationality. Alright, this one has fallen. She won't try to tame me like before.

To be sure, I ask.

"Chiaki, what are you to me?"

"I'm Horagasaki-kun's pet. Even though I'm such a masochist, please do as you like with my body?♡"

Perfect. I've tamed her just like Amasawa. Now, the night is still young.

"Chiaki, are you staying over tonight?"

"Yeah... I want to be lovey-dovey with you, Horagasaki-kun///"

"Thanks, Chiaki. But stop drugging me, okay? If you do that again, I'll hate you."

"Y-yeah... I was crazy too. I'm sorry... But, just for now... I want you to look at me the most///"

Blushing with genuine feelings, Matsushita says this. Damn, she's too cute. Unable to resist, I hug her and forcibly take her lips.

"*Smooch... Lick lick... Phew*"

"*Lick... Hehe, come on, Horagasaki-kun. Pamper my perverted pussy, okay?*"

"Leave it to me, I won't let you sleep."

"Yeah♡"

Well, I ended up doing it a lot. With a massive creampie, we woke up the next day at 2 PM. Of course, my hips and groin were sore, but the yandere Matsushita was gone, and I felt a huge weight lifted off my shoulders.
