Sona had one hand holding Altair's testicles, and she felt them suddenly swell. Apparently, Serafall thought it too, as she made a move to pull away.
"Where do you think you're going?" asked Sona as she grabbed her by the hair and forced her to sink completely onto Altair's cock, the semen ending up going straight into her stomach at first.
Sona had a wicked idea, letting Serafall pull the cock out of her throat and finish with a few loads of semen in her mouth. She looked into her sister's shining eyes as soon as she tasted Altair's seed on her palate.
"Are you enjoying it?" Sona asked, adjusting her glasses as she spoke. "Big sister... did you enjoy sleeping with my boyfriend behind my back?" Serafall looked at her with wide, innocent eyes. Sona didn't believe for a moment that she felt any remorse. "Don't swallow it," she ordered as she watched her take the cock out of her mouth.
"Spit it on Sona's feet," Altair said.
Sona stared at him with wide eyes. Altair's request was precisely what she had planned to do.
Sona suddenly felt warm liquid drip onto her small foot. The white semen was quite noticeable even against her white skin. Serafall looked up after leaving the semen there, opened her mouth, showing that it was almost clean.
"I didn't ask for that, Serafall!" Sona scolded her, more in the spirit of role-playing than actual anger. After all, she had planned to ask her to do the same thing. "Clean it up immediately," she said, bringing her foot close to her face.
Serafall didn't say a word. She stuck out her tongue and masterfully began to lick her foot. Sona held on to Altair so she wouldn't fall, and as she "held on," she took his cock as a support and began to masturbate him while her sister's tongue ran over her toes.
It took only a few minutes for Sona's feet to be ready. Serafall didn't stop there. The perverted sister continued licking her feet, from the soles to the heels. Sona felt a tingling sensation that was too good to stop. She felt her boyfriend's hand on her butt and squeezed his cock. Sona went to the base and applied pressure, then her hand ran all the way up the shaft until a small drop of semen came out, which she caught between her fingers.
"Onee-chan! Come here!" she ordered her sister.
Serafall was like a pet at that moment. Sona wondered why she acted that way in his presence. Was his desire to sleep with her so strong that he could endure whatever she put him through? Or was she happy being treated that way? Sona brought the semen-covered finger to her sister's mouth. Her fingers were small, but she managed to touch the back of her throat.
"I'm going to put it in, no problem, right?" Altair warned as the tip of his cock entered Sona's tight, wet pussy. He had previously removed the king's piece from her pussy.
Sona rolled her eyes, perhaps exaggerating a little, and gave her sister the most brazen and lascivious expression she could muster.
"So-tan..." Serafall spoke after a long time. "Is he putting it all the way in?" Serafall's voice was barely a whisper that would be lost in the air if Sona moaned a little louder.
"Yes... all the way in... he's reaching places my fingers have never reached," Sona looked at her sister's glassy expression. Serafall wasn't looking at her body disguised as a magical girl; she wasn't looking at where Altair was thrusting his cock deep inside her. She was looking at her face, watching it contort with the pleasure her body was feeling. "He is giving me all the pleasure I deserve in my life... One-sama, thank you for bringing Altair to Japan, thanks to that I can enjoy this huge cock as much as I want!" she said as she caressed her head with genuine affection.
"Doesn't it hurt? Being stretched so wide?" asked Serafall, her voice laden with morbid curiosity.
"No... there's no pain... it doesn't matter if it feels like he stuck a baseball bat inside me," Sona could still feel the pawns in her anus, vibrating. She was slowly getting used to them, but it seemed that for Altair, that was a crime. He changed the patterns every minute, leaving her no time to rest.
"Yes... It's quite big... huge, Sona... I'm so glad that such a big penis is inside you." Serafall's cheeks were flushed as one of her hands went under her pink skirt to reach her pussy.
"Don't masturbate!" Sona told her.
Serafall pulled her hand away, like a child pulling her hands away from the cookie jar after her mother walked into the kitchen. "Get up and come here," Serafall jumped at hypersonic speed. "You've been a bad big sister." Sona's hand slapped her crotch gently, not wanting to cause her any real harm.
"Ahh! So-tan," Serafall clearly didn't care about the punishment at all; she just moaned her name. "How embarrassing!" she covered her eyes with her hands.
Sona saw a glimpse of herself in Serafall. She had never seen her outgoing sister like this before, self-conscious; it was adorable.
Sona moved her hand down to her sister's pussy. Her hands caressed it; it was completely exposed to her.
"Altair... do you have the king piece?" she asked the man who was still thrusting into her from behind.
"Here," he handed her the piece.
Serafall looked at it, one of her eyes peeking out from between her fingers. Sona looked at the piece, completely covered in her fluids, and, in front of her older sister, licked it. She didn't know if the way her tongue ran over the piece was sensual, but Serafall's legs trembled.
When the piece was clean, that is, without any strange taste, Sona brought it to her sister's pussy. She inserted it slowly, her sister's pink pussy swallowing it little by little, the wet sound as it slid in making Sona squeeze her own pussy. A moan from Altair told her that he was enjoying it as much as she was.
Sona's fingers entered Serafall's pussy, taking the piece deeper. Soon it began to vibrate, and Serafall let out a small moan. Sona squeezed her pussy to thank Altair, who spanked her and continued to fuck her.
"Ohhh!" Sona moaned as she felt the pawns in her ass move in different patterns. She had to hold on to Serafall's legs to keep from falling. She looked at her sister's pussy in front of her face and for a moment considered returning the favor.
"I can't indulge her that much," she thought as she backed away.
"So-tan, your hand, your hand is—" Serafall covered her mouth. Sona really started to masturbate her more eagerly. Altair's fat cock, the sloshing of her fingers, and Serafall's muffled moans were bringing her to the peak of pleasure.
"Make your penis as big as you can, I don't care if you break my pussy," she said to Altair, sliding four fingers inside her sister herself.
Altair did as she asked, thickening his cock and beginning to penetrate her fiercely. Sona rolled her eyes, falling to her knees from the thrusts, Serafall ending up in front of her, kneeling. Sona stuck her whole hand in. Just out of curiosity, she took the king between her fingers and brought them close to Serafall's G-spot.
"You dirty girl!" she said to her older sister as she squirted in her face. But deep down, Sona didn't care. "Come inside me! No! Come in my ass!" she said to her boyfriend—an idea formed in her head.
Altair came inside her anus, he didn't get the cock all inside because of the chess pieces she had inside.
The semen shot out like a jet of water from an elephant's trunk.
Sona abruptly pulled her hand out of Serafall's pussy. She had lost consciousness a little as she fell to the floor.
As soon as she regained consciousness, she crawled away, looked over her shoulder at Serafall, who practically salivated as she looked at her battered pussy. Altair looked at both of them with a sense of utter disbelief.
"Altair!" Sona called the man. "It's Serafall's turn... meanwhile, I'm going to use this!" she said as she picked up the giant dildo that Serafall had brought into the room.
