for Advance Chapter
July 5th, Wednesday 21:30
Standing at the door of a room on the fifth floor of the apartment, Itsuki took a deep breath and rang the doorbell.
"Are we there... Itsuki-chan..." Yotsuba, standing behind Itsuki with a flushed face, asked. Now Yotsuba still thought the destination was a convenience store.
"Hmm... We're here. It will only hurt the first time, and it will feel very comfortable afterwards..." Yotsuba didn't understand what Itsuki was saying.
Itsuki's heartbeat quickened, and the ten-second wait seemed so long. The door opened with a click, and two big hands grabbed Itsuki and Yotsuba into the house without giving them time to react.
In a certain apartment
"Even if we didn't use so much force, we wouldn't run away. How impatient are you!" Itsuki's arm was pulled so hard that it hurt, and a red handprint was left on her fair skin.
"Itsuki-chan... what is this...?"
The sudden pull made Yotsuba, who was originally confused, sober up.
"Ah!? Ah!? It hurts!" Yotsuba was just pulled into the house when she was picked up from behind and taken to the master bedroom in the house. With the spring bed's "creak", Yotsuba was thrown heavily onto the bed.
"Who are you...?" Yotsuba, who had recovered her strength, rubbed her eyes and looked at what was happening in front of her in disbelief. Four more people came in from outside the door, and the last one was Itsuki who was pulled in together. The four strange men in front of her who were surrounding her and making obscene laughter and slurping sounds were four different body shapes.
However, they were not strangers, but the four new tutors that Yotsuba had met in the past few days. In her impression, they were all well-dressed and good teachers who gave simple and easy-to-understand lectures, especially Tonda, who had a fat middle-aged body and a good-natured face. She thought Tonda must be a good person.
Now, each of them was naked from the waist up, and their underwear had already erected a big tent on their lower body, which was not aesthetically pleasing at all.
The four of them slowly approached Yotsuba with lewd smiles.
"No, stop it! Itsuki, save me... woo woo" Danny and Tonda held down the four limbs, and Saruyama began to take off Yotsuba's clothes piece by piece, while Ogu set up a digital camera and took the first nude photo of Yotsuba.
The whole process took less than two minutes from the moment they were brought in. Itsuki just stood there blankly, watching her sisters being stripped naked and photographed naked, just like herself at that time.
"Hey, what's the amount of water coming out? Isn't the underwear all wet?"
Saruyama took out the underwear he had just taken off and showed them to everyone. "Danny's potion is really powerful."
"Huh? Itsuki, how much potion did you give Yotsuba?" Danny asked.
"Huh? Huh?" He was startled by the sudden question. "Ten... about ten drops. I put it in the tea."
"Are you trying to kill your sister?" Danny was a little helpless.
Danny's words made Itsuki panic a little. "No... no, I'm afraid the potency is not enough... that's why..." Itsuki spoke more and more quietly.
"Then there's no other way. Let's save Yotsuba, hehehe."
Danny gave Itsuki an potion. Three drops of it mixed with a cup of water is enough to make people aroused. It is so powerful that Itsuki dropped ten drops in.
Everyone looked at Yotsuba, who had covered herself with the quilt on the bed.
"Well, my mission is completed, I will leave first." Although Itsuki felt a little bit reluctant, she had nothing to do next, so she wanted to leave first. This was the original plan.
How could the high school girl's naive wishful thinking come true.
Ogu grabbed Itsuki who wanted to leave with one hand, and closed the door with the other hand and locked it neatly.
"Wait a little longer, Itsuki, don't you want to see your beloved sister's first experience, hehe."
It is still unknown whether everyone intends to let Itsuki go.
The four of them looked at Yotsuba who covered herself with the quilt. "Wuwuwuwu..." Sobbing continued to come from the quilt. Yotsuba, who was innocent and lively humming a song before, can only hear her crying now.
"So, who will go first this time?" Danny said, "If no one is willing, I will go first."
"Let's play rock-paper-scissors like last time, but exclude the last one. You have already taken Itsuki's virginity."
Itsuki, who was listening to the conversation of the four people, was a little surprised. "You decide your virginity by playing rock-paper-scissors?"
In the end, Butada won.
Butada dragged Yotsuba out of the quilt with a smile. The strong potion had already made Yotsuba unable to struggle, and she could only let Butada do whatever he wanted. Where Yotsuba was dragged, there was a line of water stains, not only the smell of lewd water, but also the smell of urine.
"Huh? Yotsuba wet the bed, what a child." Butada said with a smile.
Itsuki looked at her sister who was already a high school student and still wet the bed, and she lowered her head in shame.
Butada dragged Yotsuba to the bed and lifted her legs. Although her clothes had been taken off, her sneakers were still on her feet.
Yotsuba crossed her arms and covered her eyes. The twitching of her chest showed that she was still crying. It didn't matter.
Butada pulled out his thick cock and rubbed it in circles around Yotsuba's pussy. Every time the tender petals touched the cock, they would twitch.
"April-chan, I'm coming, hehe." Mr. Butada, who was regarded as a good man by Yotsuba, was going to use his cock to defile Yotsuba.
Butada used his cock to separate the slightly trembling petals, forming a shape where the pink petals wrapped around the glans.
"One, two-three!"
With a whoosh, the cock slid in.
"Oooooh!! No! It hurts, pull it out! Pull it out!"
The pain made Yotsuba stop crying and let out a pleading cry.
"Hmm?" Butada pushed forward again.
"Teacher Totada, please, don't do that again... oh oh♡～～"
"Hmm?" Totada said, "Yotsuba-chan, it seems like you're not a virgin anymore."
The first insertion was easier than expected, and there was no resistance at all. To confirm, Totada went a little deeper.
The two insertions directly made Yotsuba climax.
"It's normal for high school girls not to be virgins." Ogu said,
"But Yotsuba-chan is really a bad boy, even though your sister is still a virgin."
He looked meaningfully at Itsuki who was watching from the side. Yotsuba, who had just reached orgasm and was now panting, followed Ogu's gaze and saw Itsuki standing by the wall.
"Ha♡...ha♡...Itsuki-chan...help me..."
Faced with her sister's call for help, Itsuki chose to look away, and coupled with the news that she had just learned that Yotsuba was no longer a virgin before this, Itsuki frowned.
"Hey, bad boy Yotsuba-chan, who did you do it with for the first time? If you don't tell me, I'll treat you to a big cock."
"Mm ♡... Don't tell me... Pull it out quickly ♡" Butada thrusted threateningly for a while but failed to make Yotsuba surrender, so he continued thrusting.
(Perspective changes to Itsuki)
"Don't tell me," I shouted in my heart.
I can probably guess who Yotsuba's first experience was with. As long as Yotsuba doesn't say it herself, I can get along with him without caring.
"Try this!" Butada, who maintained a normal position, pushed forward vigorously. The part of the cock that was not inserted into the vagina before was now completely inserted.
"Ah ♡♡♡~ No no no no no no no... Teacher Butada ♡. No ♡♡..."
I didn't dare to look at Yotsuba's painful expression, but I also hoped that she wouldn't say that name.
Saruyama and Danny watched Butada torture Yotsuba with interest, and Ogu took a digital camera to record it all.
"Yoto-chan is a good girl. If you tell me who it is, I'll let you rest."
Butada looked kind and comforted Yotsuba, just like a gentle elder...if his penis was not inserted into Yotsuba's vagina.
"Don't say it!" I shouted again in my heart.
"Itsuki-chan...save me." I didn't dare to look at Yotsuba's eyes again, closed my eyes tightly, and turned my head away.
(The perspective changes to God's perspective)
Seeing that Yotsuba refused to say anything, Butada had to give up the attack. I saw Butada keep the two of them connected and close to Yotsuba's ear. From the side, it looked like Butada was pressing on Yotsuba. I was really worried that Yotsuba would not be able to bear it.
"If you say it, I promise to let Itsuki-chan go back safely and not do anything to her again." Butada said softly to Yotsuba.
Biting her lips lightly, Yotsuba chose her sister's safety without hesitation between her self-esteem and her sister's safety.
"I... I said... yes... um ♡" When Butada got up from Yotsuba, his cock accidentally jumped inside Yotsuba's pussy, and Yotsuba gasped.
"No..."
"It's Futaro-kun..."
After hearing the expected name, Itsuki was like a puppet with its strings cut off, her eyes lost their light and she slumped to the ground.
"Hahaha, it's that Uesugi guy after all." Ogushi
"I guessed it was his." Saruyama
"He's not as incompetent as we thought." Danny
"That means that the person I'm fucking now is Uesugi-kun's girlfriend." Butada's words made the other three excited.
Danny signaled Butada to change positions and he wanted to join in.
With a "puff", Butada pulled out his cock, bringing out a lot of vaginal fluid. He grabbed Yotsuba's waist with both hands, turned Yotsuba over, and then pulled up Yotsuba's upper body. Now, Yotsuba was kneeling on the bed with both knees, and her body was supported by Butada who was holding her breasts.
"♡Why... pull it out♡... hurry up... hurry up and put it in♡... teacher♡ hurry up and put it in♡ my pussy... it's so lonely♡"
Yotsuba put down her burden and was taken over by the effect of the aphrodisiac after thinking for a while. The reason she was still resisting before was because her sister was still beside her.
"Ah♡♡♡～～～ the big cock♡♡♡ is back♡♡♡."
The moment Tonda inserted his cock from behind, Yotsuba immediately regained her spirit.
Danny stood on the bed and took out the extra-large black cock and put it in front of Yotsuba. Yotsuba was like finding a treasure.
In order to prevent it from escaping, she immediately put Danny's black cock in her mouth and sucked it. Only the front end of the huge cock was wrapped by Yotsuba's small mouth.
"It feels so good♡♡The teacher's big cock feels so good♡♡♡"
"Slurp♡♡♡♡Mmm♡♡Mmm♡Mmm♡The black cock♡♡♡ tastes so good♡... Slurp"
With the cock in her mouth, her ass was still catering to Tonda's thrusting.
"Other people's girlfriends are really different." The two thought at the same time.
"When will it be my turn? I can't wait any longer." Saruyama, who was always assigned the last position, expressed his dissatisfaction.
"Isn't Itsuki-chan still here? You can use Itsuki-chan first."
Itsuki was finally remembered. At this time, Itsuki was slumped on the ground with lifeless eyes.
Although she was prepared in her heart, until Yotsuba admitted her relationship with Futaro, she realized that her own sister had indeed had sex with the person she liked.
This fact made Itsuki's tense nerves break like a string. As long as her grades improved, Futaro would come back, the new teacher would leave, and her affairs would not be known by Futaro.
If the confession went smoothly, the two would go to college together, get married immediately after graduation... and give birth to Futaro's child. Itsuki, who had once fantasized about this... now couldn't even fantasize about it.
"Hehehe, look, Itsuki, Yotsuba-chan is really amazing, Futaro is so happy."
Itsuki was pulled up from the ground by Ogu without knowing it, and was stripped naked. Now she was only wearing a pair of white knee-high socks. She was leaning against Ogu's chest and sitting on his thighs. Her
two white thighs were spread apart, and Ogu's fingers were playing with Itsuki's clitoris.
Hearing the names of Yotsuba and Futaro, Itsuki slowly raised her eyes and looked at Yotsuba.
Danny and Tonda exchanged positions. Tonda leaned against the head of the bed and looked at Yotsuba, who was lying like a bitch, burying her head between her legs, holding the testicles with her hands, licking them from the base to the glans without leaving a single bit.
"Oh♡♡the black cock♡♡the teacher's black cock♡♡♡is coming♡♡♡♡♡…"
"♡♡♡move♡♡♡♡move faster♡♡♡♡teacher♡♡♡～～"
Seeing that Danny didn't move, Yotsuba started to act coquettishly towards Danny.
"Yotsuba-chan, concentrate here too, or I won't give you my semen."
"Okay~~♡Teacher Butada♡♡"
"Mmm♡♡hmm♡♡…mmm♡Teacher's black cock, don't move suddenly♡mmm♡♡…ah♡So deep♡♡The cock is so deep♡♡Ahhh♡I'm coming♡Yotsuba's cheating pussy is coming♡♡♡Oh oh♡♡…"
"Yotsuba-chan, stop mouthing." Butada urged.
"Hah♡♡…hah♡♡…I'm sorry♡♡…Teacher Butada…please let Yotsuba rest♡♡."
"Mmm♡The black cock is here again♡♡Even Futaro hasn't been to a place♡The black cock is so powerful♡♡"
Looking at Yotsuba who was cheating, Itsuki's eyes regained some spirit.
"Futaro likes Yotsuba, not me, not Nino, and not Miku.
So is there any reason for me to be reserved? It was me who hurt Yotsuba like this, and this is probably retribution."
Then enjoy it. I have lost the qualification to be with Futaro, but there are four of them here to fill this emptiness.
"Huff, huh, huh♡."
"What's wrong, Itsuki? Is the massage here very comfortable?"
"Yes♡ Master♡... Please make Itsuki the little bitch more comfortable♡"
"Hmm? How did Itsuki become so active? But, okay, as you wish."
Itsuki has been looking forward to it since she came in, and her vaginal fluid is not less than Yotsuba who took aphrodisiacs. Now that Itsuki has let go of her worries, she can enjoy the pleasure of making love to her heart's content.
Obuta pulled out his penis, and his target was not the vagina, but the anus.
"Ah♡♡... Master, where are you inserting it♡" Itsuki
"Is it not possible here?" Obuta
"No♡Of course you can♡. The master can insert his dick wherever he wants♡hmm♡♡"
"Saruyama-nii♡Itsuki's pussy is still empty♡Don't worry about Yotsuba-chan, come here."
Itsuki said to Saruyama who was still waiting in line to fuck Yotsuba.
Saruyama, who had been holding back for a long time, saw Itsuki actively open her legs to welcome his dick, so he walked directly to Itsuki who was leaning against Obuta with his dick in and out of her asshole.
Saruyama also imitated Tonda and first used the glans to separate the flesh petals and let it wrap around the glans.
Then, push hard.
"Oh oh♡♡♡Saruyama-nii's cock♡♡Long time no see♡…Welcome back♡"
"Ah ah♡…My pussy and my asshole are fucked at the same time♡♡♡So comfortable♡I've never felt so comfortable before."
Pah, pah pah, pah, pah, pah, pah, pah
"Ah ah♡Saruyama-kun has also come to love Yotsuba's cheating pussy♡Saruyama-kun is so helpful" Yotsuba
"The master's black cock♡ tastes so good♡" Itsuki
"Mmmmm♡♡♡Saruyama-kun♡ Cum inside…♡Fill Yotsuba's cheating pussy with cum♡" Yotsuba
"Mmmmm♡…The cum is in my ass♡"
The sound of flesh colliding with flesh in Itsuki's room, the sound of water "puffing, puffing" produced by the cock's continuous thrusting, the man's angry shouts, the girl's tender gasps, came one after another.
July 6th, Thursday, 03:00
"Ha♡…ha♡…ha♡♡"
"Ha ♡...Ha ♡♡♡..."
Yotsuba and Itsuki lay side by side on the bed, panting. The severe exhaustion of their physical strength could not stop the pleasure brought to the two of them by the continuous orgasms.
The four ejaculated a lot, forming several small pools on the bed, and semen continued to flow out of the sisters' pussies and anuses.
Itsuki and Yotsuba held hands and looked at the ceiling.
"Ha ♡...Ha ♡...Itsuki-chan...thank you so much for today."
