Chapter 2: The Reason
"So how is it, Onii-chan? How does Arisu-chan's mouth-pussy feel? Does it feel good?" asked Yoriko.
"It does," he struggled to respond.
She was sucking his penis as if she was trying to suck all of his semen out. It was like an extremely powerful vacuum that refused to let go of his shaft.
The entire time she was blowing him, her lavender eyes remained looking up at him.
Slurp. Slurp. Slurp.
"Here, take a look at this. This was how Arisu usually looked at high school," said Yoriko as she showed him a picture of her at school a year ago.
She was standing in front of the student body addressing them with confidence and elegance.
"She's so cool that even girls have a crush on her. They say that they all wish to be like her."
Slurp. Slurp.
"And yet, that cool girl is so submissive and feminine when it comes to your cock. Isn't she so adorable? ♡"
Seeing the drastic difference between the two sides of Arisu made him feel so aroused that he grabbed the back of her head, pressed it down to the roots of his cock.
"I'm going to cum," he groaned.
Arisu couldn't respond but her seductive eyes told him to do it.
"Ahhh~"
Shooting a thick load inside her mouth, he slowly pulled it out after the last bit was released.
As his limp cock hung downwards, she opened her mouth to show the semen that was in her mouth.
Then she swallowed it and showed her mouth again, proving that she had swallowed all of it.
"Has your libido gone down since the last time?" asked Yoriko, grabbing his limp cock and cleaning it up by licking the bottom of the shaft.
"...No," he responded. "It's only gone up."
"Great! ♡"
Gaining motivation, she began showing off her tongue technique, focusing on the bottom of the glans, and slowly but surely, his penis began to take shape again.
"There we go, ♡" she said as she kissed the tip before opening her mouth and started sucking it.
Slurp! Slurp! Slurp!
"Onee-chan, you made fun of me but look at you. Look at that lewd face you're making."
Yoriko looked like a proper gyaru slut.
"Don't act like you're not as horny as me," said Arisu as she pushed her head forward, causing Yoriko to choke, snot coming out of her nose.
Arisu returned the favor and showed a picture of Yoriko in her track and field uniform, getting ready to run. Then she swiped and showed a picture of her getting first place.
"Everyone believes that she spends all of her free time training to get faster. You want to know the truth Onii-chan?" asked Arisu.
"Yes."
"After she's done with club practice, she heads to her bedroom and spends hours every day masturbating to pictures of you."
Yoriko's eyes widened; she didn't expect her younger sister to know that.
It was supposed to be a secret.
"Wasn't it you who used to sneak into Onii-chan's room at night to suck his cock, Onee-chan?"
Yoriko pulled her head back and took a few breaths to regather herself.
She turned to her sister and apologized, "Sorry Arisu-chan. Here, why don't we make up by sucking it together?"
"Fine."
The two of them began sucking his penis, taking different sides. They moved their heads left to right, tracing their lips against his shaft.
Then as Yoriko continued sucking the side of his shaft, Arisu made her way over to the glans and she began focusing on it.
After a minute, the two of them swapped places.
In each hand, he was holding the hand of one sister.
"Ha... ha ha..."
"You're about to cum? Go ahead," said Arisu while Yoriko was sucking on his ball, massaging it with her tongue.
'His balls are adorable! ♡ So cute! ♡ Onii-chan is so cute! ♡'
Yoriko heard her sister's words and pulled away. She stood up and watched as Kojiro grabbed her sister by the head and thrust the entirety of his penis down her throat.
"Come on, Arisu-chan! Really open that throat of yours. Don't spill a drop. Don't be wasteful," she encouraged her sister.
Kojiro, unable to hold it back any further, released a second load down her throat.
Arisu was being violated but she was extremely aroused as a result, her pussy was quivering, and her panties started to change color from the liquids that were leaking out.
Kojiro pulled his penis out of her throat and Arisu began sucking away the residue that remained on it.
"Look over here Arisu-chan! Show me how you clean up Onii-chan's cock," Yoriko said as she pointed the camera of her phone at her.
"Say cheese! ♡"
With his penis pressed against the left side of her mouth, she made the peace sign and posed for the picture.
Showing the two of them the picture that was taken not only rejuvenated Kojiro who was ready for round three but it also aroused Arisu who got to see a different side of herself.
Wanting Kojiro to herself for at least a moment, the smart Arisu turned to her older sister and asked, "Onee-chan, I'm starving. Onii-chan, you're starving too right?"
He wasn't particularly hungry, having just eaten an hour before they announced their arrival back into his life but he played along and nodded his head.
"Ahh, is it time for me to showcase how much I've gotten better at cooking? Onii-chan, don't fall for me after you eat what I cook up, okay?" asked Yoriko, teasing him.
The last time Kojiro tried her cooking, he got food poisoning so he didn't have much expectations.
"I'll go whip something right up so just have sex in the meantime," Yoriko winked as she walked into the kitchen.
There weren't a lot of ingredients in the fridge.
"Just as I expected," she muttered. "He can't live properly without us. We'll have to clean his room later too."
Grabbing what was useable, she began to cook a simple meal.
Behind her, the sound of meat slapping against each other could be heard.
"Ugh~ Ack ahh~ Unf~ Ugnh~ Onii-chan! I've missed this cock so much! ♡" screamed Arisu as she sat on top of his lap, holding herself up with an arm around his back.
If any student from their university heard the words that just came out of their mouth, they would assume it was edited or even generated by AI.
There was no way that the innocent role model student whom teachers praised for her perfect character, Yanase Arisu, would be moaning like that.
There was no way that she was bouncing up and down the dick of a college student who was three years older than her.
But — she was.
Arisu had taken off her shirt and her bra; Kojiro didn't hesitate to suck on big boobs that were tempting him.
It had been five years since she got to feel this warm thick penis inside of her.
This was the cock she'd been dreaming about. This was the person who she wanted to see, wanted to kiss, and wanted to fuck.
'This must be heaven! ♡' Arisu thought. 'My dream has finally come true.'
"After I'm done cooking, I'm next, got it!?" asked Yoriko who had fluids dripping down her leg as she listened to the sexy sounds.
As Arisu ate, she watched as her older sister get fucked from behind. Her back was arched and her hair was pulled back with two hands like the leash of a horse.
"Ha~ Hah ha~ Uhn~ Onii-chan! Onii-chan! ♡ Harder! Ahn~ Harder harder! ♡"
Kojiro made sure to mark her womb as his territory by shooting a thick load of cum inside of her.
"That was so much," said Yoriko, lying on his bed, touching her full stomach.
It was getting dark and three of them cuddled on the bed with Kojiro in the middle.
It was peaceful and quiet for a few minutes before Yoriko asked the question that had been lingering in the air for hours, "Onii-chan, why did you move and leave us?"
Arisu didn't chime in but her eyes said that she also wanted to know.
Kojiro let out a sigh, knowing that he was going to have to explain eventually. Might as well get it over with.
"It was because my university is close to here. Well, that's what my excuse was. The truth is, the two of you were ruining me."
"Hmm?"
"We were?"
The two sisters were confused and nervous about what he meant by that.
"Yes. I knew that if I didn't escape you two, I'd never be able to get anything done. Your bodies, your pussy... they were the only thing on my mind and I needed to fulfill my late dad's dream of me getting a college degree so... that's why I moved."
Hesitantly, Arisu asked, "What about now? Will we continue to ruin you?"
"Yes," he answered.
Their hearts dropped.
"But I don't care anymore. I've missed you two too much. Getting a degree means nothing if I have to stay away from you two. I was actually... going to contact you two next month for Arisu's birthday."
Their hearts pounded, their eyes fluttered, and their pussies quivered.
"Onii-chan," said Yoriko, rolling her body on top of his. She sat up, her bare vagina lips pressing down on his soft penis. "Another round? ♡"
