Ichika Orimura spent his long weekend at home after finishing his tests.
"I... didn't sleep well..."
I sat up from the living room sofa and stretched. I shook my head to clear the sleepiness. I got up and went to the kitchen to quickly prepare breakfast.
"Hurry, I have to hurry..."
It was a precious holiday morning, but I had no time to relax. I just cooked in a hurry. If I don't hurry, I'll...
"Ah, aaaah! So thick! Thiiiick! Ann!"
"Hick! Damn, she's already up...!"
A woman's high-pitched voice from the second-floor bedroom echoed all the way to the first-floor living room. I forced my frozen body to move, ate the simple breakfast I made in a rush, and washed it down with water.
"Nngh, nngh...! ...Hah, hah..."
"Ah! Not good, not good...! Niiih! Ah, ah, ah, it's so violent..."
The sounds of lovemaking from the second floor grew louder and more intense. There was no time left.
"Nngh... I have to wash my body..."
"...! Ch-Chifuyu... aniki..."
"Hmm?... Ah, you were here."
Just as I was about to clean up before someone came down, Chifuyu Orimura, the mistress of the house and my older sister, came down completely naked. She gave me a cold glance. Even though I was her brother, she was so nonchalant about being naked and seen that I felt like I was no longer in her thoughts.
"Ah...! I'm gonna cum! I'm cumming! Aaaah! Yaaah! Niiih, niiihn!"
"Honestly, Madoka is so lucky this morning. To be able to have the first semen of the day ejaculated inside her."
Chifuyu-ane heard the moans from the second floor and muttered to herself, not really talking to me, as she prepared to take a shower.
From the corner of my eye, I saw red hickeys on Chifuyu-ane's chest and neck, which made me guess what happened last night. Chifuyu-ane caressed her stomach lovingly, closed the door to the changing room, and went in for a shower.
"Ah... aaaah!!... Ah, an! N-not good! Nnngh! I'm cumming...! I'm cumming, but...! Ah! Ah!"
A particularly high-pitched moan came from upstairs, and even though she had reached an orgasm, the sounds of lovemaking didn't seem to be stopping. The woman's voice, which should have climaxed, was starting to get colored with lust and become disheveled again.
"Ah... like this... fufu...!"
Through the door of the bathroom, I could hear Chifuyu-ane's happy voice.
I quickly finished cleaning the kitchen and tried to leave the house, not knowing what would be said to me later. I endured the lustful feelings caused by the woman's moaning from upstairs and finished washing the dishes.
Since I was still in my pajamas, I changed into my clothes, pushed the blanket on the sofa into the corner, which was the only space I was allowed, and tried to leave.
"Ah! Aaah!! Yaaah! Yaaah! Ah... uunngh! It's coming out, something hot is coming out! Ann! F-waaaah...!"
"…!"
Just as I was about to leave, a woman's voice, sharper than anything before, reached my ears. From her words, I understood that the woman had had semen ejaculated inside her and had climaxed while receiving the man's seed directly with her genitals.
My body stiffened at the vivid reaction, and I stopped moving for a while. The moans from upstairs also quieted down, probably because the man had climaxed.
Clank
"Ah..."
"Phew... I'm disappointed the scent of Kiyono that I had soaked in has been washed away, but I was told to cleanse myself and wait, so..."
While I was frozen in front of the door, Chifuyu-ane, wearing a sexy purple lingerie, came out of the changing room and returned to the living room with a hairdryer and a towel.
Her slender, long limbs, her toned stomach, and in contrast, her abundant and soft breasts... Even though she was my older sister, Chifuyu-ane's lingerie-clad figure was artistically beautiful, and I couldn't help but stare, even though my mind told me not to.
Chifuyu-ane noticed me frozen and gave me a cold look, sighing.
"Haa... perfect. There was something I wanted to tell you. Stay in the house and don't go out."
"Ah, no, I..."
"Shut up. I'll say it again. 'Stay in the house and don't go out'."
"...Yes..."
Ordered strongly by Chifuyu-ane, I let go of the doorknob and sat down on the cushion in the corner of the room.
I had finally gotten out of the academy where I had no place to be, but if I didn't leave quickly and escape, I would suffer a terrible fate again.
Chifuyu-ane didn't even glance at me. She sat in a chair in her lingerie and dried her hair with a hairdryer. Her long, beautiful black hair looked even more beautiful. The contrasting colors of the purple lingerie and her white skin made for an artistic beauty.
(Damn...! This is weird...! Why...! I've never been this excited before when I saw Chifuyu-ane in her lingerie...! Ever since I entered the academy, I've been strangely excited by Chifuyu-ane's defenseless body...! What's wrong with me...!)
I lowered my head to try to get rid of my lustful thoughts. Ever since I entered the IS Academy, I feel like everything around me has gone wrong. It might just be my imagination, but being excited by Chifuyu-ane's lingerie right now is one of those things.
Eventually, a naked couple appeared from the stairs.
"Good morning... nngh... ah..."
"Good morning, Chifuyu."
"Good morning, Kiyono...!"
"Ah, aan...!"
"Come on, Madoka, walk properly."
"Y-yes... I'm sorry... an!"
Madoka Orimura and Kiyono, who was holding her and fondling her breasts, appeared, making it clear from their voices that they had been having sex this morning.
Neither of them tried to hide that they had been having sex this morning, and they were hugging each other nakedly. A trace of what Kiyono had done was left on Madoka's crotch, with cloudy semen dripping down to her thighs. Kiyono's entire erect penis was wet and glistening.
Kiyono squeezed and crushed Madoka's breasts hard, leaving a handprint, as if to hurry Madoka, who was unsteady on her feet. Madoka leaned her weight on Kiyono and somehow managed to continue walking.
"Well, the first ejaculation of the morning was a huge amount. As I thought, Madoka is better suited for sex without a condom than for assassination or infiltration."
Kiyono handed the stumbling Madoka over to Chifuyu and sat down on the sofa. Chifuyu-ane's gaze was fixed on Kiyono's erect cock.
"You two were all over each other last night too... you two drained a lot of semen out of me, the sheets are all sticky now. Oh, Madoka, you go take a shower too. I still have things to do."
"Y-yes... excuse me... nngh..."
"Are you okay, Madoka?"
"Ah. Thank you, aniki."
Madoka thanked Chifuyu-ane and stumbled her way to the bathroom.
As Kiyono said, it seemed like they had been doing it a lot with Kiyono since last night.
Currently, four people live in this house. All four of them are usually at the IS Academy, but they come back home like this sometimes.
First, there's Chifuyu-ane, the mistress of the house.
And Madoka, Chifuyu-ane's younger sister. Madoka, who was being used by terrorists, was saved by Kiyono, swore obedience to him, and is honing her skills at the IS Academy as Kiyono's sex slave.
And then there's me, a freeloader. The only space I'm given in this house, where I'm allowed to stay out of pity, is this corner. I used to have my own room, but I was kicked out to give it to Madoka. My old room is now Madoka's private room and Kiyono's sex room. It seems like the three of them were having a good time there last night. And because they were doing it with the door open, the sounds echoed all the way to the living room on a different floor. Thanks to that, I'm sleep-deprived.
(...That's right. Kiyono is the true master of this house who made the two of them submissive through sex... right...?)
When I think about Kiyono, I get a strange foggy feeling in my head. It should have been a long time ago that Kiyono was Chifuyu-ane's brother and I was living here out of pity. This strange feeling must be my imagination.
"Alright, Chifuyu, let's do our usual thing."
"Hmm, are you giving me a massage again today?"
"Yeah. It's a normal thing for a brother to give his sister a massage, isn't it?"
"T-that's true... Haa, I understand. For my beloved brother. Can I ask you to do it?"
"That's the spirit. Alright, lie down on that sofa."
Prompted by Kiyono, Chifuyu-ane lay down on her back on the sofa. Chifuyu-ane's seductive body was sprawled out.
Kiyono's cock, looking down at Chifuyu-ane's lingerie, pulsed and swelled up a size.
"Ah...!"
"Hmm? What are you staring at, Chifuyu?"
"Ah, n-nothing...!"
"Hmm?"
"…!"
Chifuyu-ane stared at Kiyono's erect penis with a look of desire. Kiyono noticed Chifuyu-ane's gaze and deliberately shook his cock to seduce her. Chifuyu-ane was trying to hide it, but I could tell she was completely captivated.
Kiyono's cock was an abnormally large size in both thickness and length, and Chifuyu-ane, who had her virginity taken by it and had its shape imprinted on her, couldn't resist him.
"Honestly... getting excited by her brother's erect cock, Chifuyu is a hopeless lustful older sister, isn't she?"
"Nngh... i-is that so bad...! It's your fault for raping your sister and making her your sex slave...!"
"Yes, yes. Sorry, Chifuyu-ane, who was made a sex slave by her brother?"
He was clearly making fun of her. Nevertheless, Chifuyu-ane couldn't resist Kiyono. She had been filled with his semen so many times that she understood who was superior.
Kiyono climbed on top of the sulking Chifuyu-ane and smiled at her. Chifuyu-ane looked at Kiyono's face and just that made her blush and her mouth hang open, dazed.
"Alright, let's start Chifuyu's favorite massage from her brother!"
"Nngh... please, I'll be in your care..."
Kiyono's hand reached for the blushing Chifuyu-ane's chest, undid her bra, and exposed her breasts. Her nipples were perked up at the tips of her well-formed breasts.
"Nngh, what a great view. The natural breasts of that Chifuyu Orimura! Your nipples are as pointed as your personality."
"Ann!"
"Alright, for Chifuyu's sake, I'll give you more of a ma-ssa-ge."
"A-ah. Please do... nngh..."
Kiyono's hand reached for Chifuyu-ane's chest and grabbed her breasts. The soft breast tissue was molded into different shapes by Kiyono.
"Nngh... as expected... Kiyono's massage feels good... nngh, an!"
"You must be tired, so I'll be sure to knead your breasts thoroughly, Chifuyu. Here!"
"Nnngh... aah, please..."
Kiyono's hand grabbed Chifuyu-ane's breasts and shook them. Her large yet well-formed white breasts jiggled, and Kiyono's palm sank into them.
(Ugh... Chifuyu-ane's breasts look so soft...!)
"Nngh, aaah... Kiyono's hands feel good. Haa, aahn...!"
"Nngh, Chifuyu's breasts feel good. Was it an E-cup? I wonder if the world champion, Brunhilde-sama, served many men with these breasts?"
"T-that's not true...!"
"Right? Because you were a virgin until I raped you. I'm so kind to take in a leftover slut, aren't I? Huh?"
"Ah, aaah, an!"
Kiyono buried his head in the cleavage of Chifuyu-ane's breasts, enjoying her breasts with his face as well. Even though it was "a brother's privilege to massage his sister," I was so jealous of Kiyono, who was fondling Chifuyu-ane's large breasts as he pleased, that I was desperately trying to hide my erection.
"Ah! Aaah! Kiyono...! Not there, don't...!"
"Oh, you make a good sound when I touch your nipple!"
"Ah, nngh...! Getting a massage from my brother feels too good..."
"Of course it does. Sisters are dirty creatures who love being touched by their brothers."
"Don't say it now, an! I already know it...! A sister serves as her brother's sex slave, so... u-uunngh..."
Kiyono's mouth licked and sucked on Chifuyu-ane's erect nipple, making a smacking sound. Chifuyu-ane let out a sigh. Kiyono's face, looking down at Chifuyu-ane, twisted with pleasure, and the cock in his crotch swelled up even more, looking grotesquely large as if it were a CG graphic.
"Nngh, Chifuyu herself is a low-life terrorist criminal, but her breasts are soft and sensitive and feel good."
"Nngh...! T-that's..."
"Seriously, men all over the world are oppressed because of Chifuyu, but she's hiding that fact and swaggering around, what a great villain she is. A trashy woman like that deserves to end her life as her brother's onahole."
"A-aah... I am my brother's... Kiyono's onahole. So, please shove that erect cock into my hole..."
Perhaps pleased with Chifuyu-ane's subservient attitude, Kiyono smiled and placed the tip of his cock against Chifuyu-ane's crotch.
A penis of a size that I couldn't imagine fitting into a woman's crotch was trying to force its way into Chifuyu-ane.
I could see Chifuyu-ane, who was a charming woman in my eyes, acting indecently right in front of me, but for some reason, my chest hurt. I felt a surge of emotion that made me want to stop it, but I, a freeloader, had no right to stop a "brother's massage for his sister." My painfully erect cock was dripping pre-ejaculate inside my pants. This incomprehensible feeling was painful, and I wanted to escape outside because I hated the cold looks and words from Chifuyu-ane and the others, but I was ordered to "not go out," so I couldn't.
"Nngh, aniki is a cheater. Aniki is the only one getting a massage from Kiyono-sama..."
"Hmm... is that Madoka...? What's wrong with getting a massage from my brother? Nngh! Besides, you got the first semen of the day ejaculated into you. Let me have the massage."
"That's right. I'll give you a massage later, Madoka, so for now, burn the sight of your older sister getting brutally fucked by her brother into your memory."
"Really? You promised, Kiyono-sama."
"Yeah. It's a matter of course for an aniki to give his imouto a massage, isn't it, f-un!"
The bathroom door opened, and a naked Madoka appeared, looking enviously at Chifuyu-ane, who was being pinned down, and raised her voice. Kiyono, looking pleased at the sight of the naked Madoka, soothed her and turned back to Chifuyu-ane, thrusting his hips to jam his "other half" into her slit.
Ju-pu
"Nngh, aaaaah! Cock! Niiih!"
Kiyono's penis pierced Chifuyu-ane in one go. A vulgar voice came from Chifuyu-ane's mouth as she was penetrated, echoing through the room. Madoka looked at Chifuyu-ane's disheveled state with pleasure.
"Ah, ah, ah! So amazing, hick, aahn!"
"Ugh, oooh... she's got a sexy body, after all, this one! Kuuh...!"
Kiyono's hips were thrust back and forth, and Kiyono's erection went in and out of Chifuyu-ane's crotch. With each thrust of Kiyono's member, a high-pitched, feminine voice came from Chifuyu-ane's mouth.
Pa-chu pa-chu, Kiyono's hips slapped against Chifuyu-ane's buttocks, and even the dry sound of her butt cheeks jiggling echoed.
"Aah! What a tight grip! That violent teacher is surrendering to my cock!"
"Hick, aaaaah! Kiyono! Nngh, aaah, haaahn!"
"Heheh, you're sticking your tongue out and showing your female face! Here, I'll suck your tongue! Nngh!"
"Nngh, aah, haaahn!"
Chifuyu-ane's wet tongue was sucked into Kiyono's mouth, making a slurping sound. Even though her tongue was being used without her consent, Chifuyu-ane's face melted with pleasure, and she swallowed the saliva poured into her by Kiyono.
"Ah... haah... nngh!"
"Drinking your brother's saliva and making a dazed face, you're a really hopeless slut, Chifuyu-ane!"
Gu-chun
"An! A slut... ah, I'm a slut... So, more massage... an! It's coming!"
Kiyono's hips were thrust again, and Chifuyu-ane's head swayed back and forth.
"When I tangled my tongue with yours, your pussy got tighter, you perverted sister! Your pussy is so wet and tight, a masterpiece for squeezing out cum."
"Aah, that's right, un! A sister's pussy, nngh, is for her brother's cock to feel good! So keep shoving it in...!"
"Yes, yes. You really love massages, Chifuyu!"
"Uah! Aaah! So thick!"
"I'm gonna cum...! Chifuyu!... Receive your brother's semen with your womb...!"
"Ah, ah, ah! It's swelling...! Aaaaah!"
"Ugh...!"
"Aah... nngh...! Ah..."
Kiyono's hips, which had been moving, stopped, and he trembled slightly while deeply connected with Chifuyu-ane. A short, lustful sigh came from Chifuyu-ane's mouth in sync with Kiyono's trembling.
"Uaah... it's coming out...! Semen ejaculated into Chifuyu Orimura's raw pussy...!"
"Ah... aah... nngh...! Faah..."
Chifuyu-ane climaxed repeatedly and moaned under Kiyono, who was relaxing with pleasure. My cock couldn't help but react to the live sex happening right in front of me, and I ejaculated inside my pants.
I could only watch as Chifuyu-ane was being fulfilled.
"Phew."
Bu-chu
"Uah..."
"Haa... feels good."
Kiyono's cock was pulled out of Chifuyu-ane's vaginal opening. Kiyono happily smeared his cock, which was sticky with love juice, on Chifuyu-ane's dazed face, leaving behind a residue of semen.
"Kiyono-sama, me next, me next for a massage!"
"I know, my cute Madoka! Nngh..."
"Nngh... chuu"
Ignoring Chifuyu-ane, Kiyono hugged Madoka, who had clung to him, and they tangled their tongues.
"Ah, haah...! A kiss... with Kiyono-sama...!"
"What kind of massage do you want after the mouth massage? Your breasts? Your pussy? Hmm?"
"An! Uh, umm..."
He separated their lips and placed his hand on Madoka's cheek. That alone made Madoka blush.
"Oh, I forgot. Hey Chifuyu, don't just lie there, do your job. You're a useless older sister."
"An!"
Kiyono's hand slapped Chifuyu-ane's breast to wake her up.
Chifuyu-ane sat up her sweaty body and gave me a cold, condescending look.
"Nngh...! Haa... Hey, Orimura."
"...Y-yes..."
"Your test results this time were... amazing."
"I-it's..."
"Aniki? What about his test results? Well, I can guess without even asking."
"Your guess is right, Madoka. For the practical exam, making him have sex with her would be an inhuman act, and I couldn't let Kiyono's important female students do that. So I had them make him masturbate. Just as Shinonono and Dunois were about to do a lesbian play for the practical exam, I had him masturbate while watching them as a side dish. The result was... he ejaculated and went limp after only a few hand strokes."
"Pff... ha, hahah! He couldn't even manage to masturbate without climaxing in just a few strokes! It seems he has a defective reproductive system!"
"Yes. Shinonono and Dunois, who had to see that, were also unfortunately disgusted and insulted him greatly. I have a video of it if you want to see it."
"...No, it's fine. There's no point in seeing the failed state of such a defective product."
"Yes. Furthermore, he scored the lowest in the grade on the IS test. What was the point of him piloting a dedicated machine for the first semester? All the female students who just got their dedicated machines recently showed amazing results."
Every word from Chifuyu-ane was a knife stabbing into my heart. But I was a failure, so I had to quietly accept it and reflect.
Madoka looked at me with a condescending look and snorted.
"Hmph, so IS can only be handled by a chosen race, I guess. It's for Kiyono-sama and the women who protect Kiyono-sama. Vile men are out of the question."
"Based on these results, I've judged that you can't keep up with the classes. To avoid being a hindrance to other students, I'm ordering you to study at home for a while."
Chifuyu-ane looked down at me with a cold gaze and threw a piece of paper at me. "Suspension" was printed on the paper that fell to the floor.
"You are to study in your room using the educational video materials until Kiyono gives you permission. This is Kiyono's consideration for not expelling you and making you a lab animal. Rub your insufficient head on the floor and be grateful."
"...Y-yes. Kiyono...sama, thank you very much..."
Prompted by Chifuyu-ane, I got on my knees and thanked Kiyono. Kiyono even shows consideration for trash like me. I have to be grateful.
"Haa... Madoka's breasts are so soft..."
"Nngh... the massage... feels good..."
Kiyono didn't even look at my bow and gave Madoka a massage.
Even though it was a brother's privilege to massage his sister, I felt helpless.
"Oh, that's right. Madoka, Rin and Houki are also coming over today."
"Nngh... Rin and Houki...?"
"Yeah. They said they wanted to come over and hang out at this house for the first time in a while. Let's include them too and do it all over the place today, in the bath, in bed, in the living room."
"Y-yes...!"
I regretted not escaping a little earlier this morning, listening to the lustful voices of the two from above my head.
