"One-Sama!" Sona screamed, feeling every ounce of pleasure in the universe concentrate on her pussy. "Al-Al-Altair!" she moaned her boyfriend's name angrily as she came on his hand.
"Yay! Magic girl juice," Serafall pounced on them, Sona watching in horror as her sister began to suck Altair's fingers, covered in her cum. "You're delicious, Sona!" she said, licking three fingers at once.
Sona... Sona didn't know what to think at that moment.
Sona watched her sister's pink tongue run devoutly over Altair's fingers. Serafall was on her knees, eyes closed, licking like a little girl enjoying a popsicle. It was another level of perversion. Sona closed her legs, her pussy spasming, which she swore was because of the chess piece inside her.
"Ahh, it's over," Serafall said with a moan of dissatisfaction. Sona couldn't even move when Serafall took Altair's hand and brought it back to her pussy, this time his fingers going deep inside. Sona bit her hand to keep from letting out a cry of surprise, which could be mistaken for a moan.
Altair touched her with that expert calm he knew so well. He didn't touch her to bring her to orgasm; it was more like he was trying to impregnate his fingers again. When his hand came out, Serafall wasted no time in unnecessary waiting and sucked them again.
"Onee-sa-sa-sama," Sona moaned. Each time she spoke, the vibrations became more intense.
"Waaah! It's over again," Serafall complained again. She repeated the above, bringing her hand to Sona's pussy. "Your panties are in the way, So-tan," she said. Sona barely reacted when her sister removed her panties in one swift motion. The young woman even lifted her feet so that Serafall could remove them quickly.
Then the Maou sought Altair's hand to bring it back to her little sister's pussy, but he held her by the cheeks.
"Why don't you take it directly?" Altair asked. Then he took one of Serafall's pigtails and brought her head without any problem to Sona's pussy.
Sona expected her sister to put up a little resistance, a symbolic struggle. But that was not the case. As soon as she was close to her private parts, she threw herself at her. Sona felt Serafall's tongue enter her desperately. She moved frantically.
She heard a splash below; her sister had her hand lost under her skirt. She was touching herself. Sona could pretend she didn't see her, but what the hell? She already had her face buried in her pussy. That was wrong, very wrong.
"Altair," she called to her boyfriend, a moan escaping her as soon as she opened her mouth. Serafall, on her knees, moaned along with her and threw herself at her with even more zeal. "This is wrong," she said, but Altair simply grabbed her neck and forced her to look at him.
"It is... two incestuous whores," Altair said, and Sona squeezed her legs around her sister's head. "It's very wrong... but tell me: do you want me to stop?" he asked her.
Sona turned her head, about to tell him she wanted him to stop, even though her body begged her to let herself go. Altair wouldn't let her, forcing their eyes to remain locked on each other.
"Altair..." Sona said pitifully.
He took her small hands and brought them to Serafall's hair. He made her grab her sister's hair with both fists.
"You've got her now, Sona..." Altair whispered in her ear. "Make her move away from you..." he told her.
And Sona intended to do just that. But for some reason, her movements went in the opposite direction. Instead of pushing Serafall away, she ended up pulling her closer as she moved her hips, smearing her pussy on Serafall's face. She had her second orgasm when one of Serafall's fingers went into her ass.
"Wait, Sera-chan," Altair said when he saw the finger enter that puckered hole. "I have a better idea."
Altair took the board this time and went for the pawns. Sona knew immediately what he was going to do. But she had already crossed the line unimaginably, so what was a little more?
She felt the cold marble enter. First one pawn, then another, and another. She ended up with a total of six pawns inside her anus. She knew she could take more, and apparently, her gaze told Altair so, who ended up putting in two more.
"Oh, my So-tan is such a perverted girl!" Serafall said beneath her, looking at her with unimaginable amounts of love.
"Onee-san, I'm about to cum again!" Sona warned her. The pawns in her ass began to vibrate and move in her rectum; she could feel her whole body buzzing.
Serafall said nothing, just opened her mouth wide as she grabbed her pussy again. Sona came, squirting. Serafall moaned loudly as she drank every drop. Sona only remained standing thanks to Altair holding her up.
She reached for Altair's belt, wanting to pull out his cock. She wanted Serafall to suck it right there, in front of her. Her clumsy fingers managed to pull down his pants, and his cock, rock hard from the show, sprang out like a spring.
"Serafall, suck it," Sona ordered, her voice coming out like when she scolded students for running in the hallways: cold and direct.
"Oh, do you want your big sister to be submissive, So-tan?" Serafall asked, his face drenched, and Sona felt so good seeing it. "I'm about to cum, So-tan, may I? Will you permit me to cum while I have your juices in my mouth?" she begged, and Sona watched her hand move so fast that she was afraid she would hurt herself. "My mouth still tastes like your pussy, So-tan, you taste so good," she said as she opened her mouth. Sona brought her foot, covered only by stockings, to her sister's pussy.
As soon as she touched it, Serafall screamed. Her foot was soaked in an instant.
"You're a pervert, One-chan!" Sona said as her sister rolled her eyes during her orgasm. She took the opportunity to take off her stockings, her feet still wet. Her sister's eyes immediately turned to them. "Do you like them?" she asked, putting them on her face and stepping on her.
"Mmmm, I love everything about So-tan!" Serafal said.
"Do you want to suck them?" Sona asked. When she nodded, "Then why aren't you sucking Altair's cock?" she asked sharply.
"Ahhh!" Serafall moaned as she went for the young man's cock. "Did you get jealous?" she asked Altair. "If your cock is as delicious as So-tan's pussy," she told him as she lunged to worship it.
Sona watched her sister's lips open grotesquely to fit that piece of meat inside. What a magnificent sight. She brought her own hand to her pussy, the other went to her ass, she inserted a finger and felt one of the pawns still vibrating.
Altair's hand grabbed her buttock, and Sona could only smile at him as she thanked him in her head for everything. She opened her lips as she stuck out her tongue, and Altair just smiled before releasing a good amount of saliva into her mouth.
"Spit on me!" Serafall complained.
Sona grabbed her by the neck and forced her onto his cock. She watched as her sister took it all in. Her eyes quickly became glassy. Sona wasn't gentle, Serafall's head hitting Altair's belly hard.
But she deserved it; she had planned all this with Altair. Sona looked at her boyfriend with narrowed eyes. Then she decided it was fine for him; he was a pervert. But Serafall shouldn't look at her little sister with lustful eyes. After that day, she hoped he would learn his lesson well enough not to look at her like that again.
If she didn't learn, Sona and Altair would remind him regularly.
