"I have to tell you guys something," Kotori said, "but I can't talk about it outside of the bedroom."
The twins nodded in understanding while they looked at each other nervously.
"You don't need to worry," Kotori reassured them, "it's nothing bad."
She sat up and pulled off the covers, revealing her older brother's figure underneath. The twins gasped as Kotori kicked Shido out from under the bed, from the look of him, he had tried to get dressed while down there.
"Now, come here," she commanded the twins, beckoning them to enter her room. They slowly crept towards her as she closed the door.
After they entered, she went straight for Kaguya and held her by the hands.
"You know that I love you both, right?" she asked them gently, "and sometimes I want to show my affection in different ways."
They nodded emphatically. They knew how great a friend she was.
"So tonight, I'm going to try something new with Shido...but I need your help to do it," Kotori explained.
The twins exchanged nervous looks.
"Your job is to have fun with him," Kotori instructed them, "and use whatever means necessary to get him to submit."
The twins looked at each other and shrugged, unsure of what to say or do. Kotori smiled at them reassuringly.
"Remember, Shido will be so aroused that he'll be powerless against you. And if he doesn't submit, I won't be able to finish what I've started," she warned them. "If he does cooperate, though, I think we might have a chance to make this work."
With that said, she turned to Shido.
"It's time to start, big brother," she announced teasingly, "now remember, if you fight back, I'll stop immediately."
Shido made a pained face.
"But if you obey me completely," she continued, "you might just get some very special treatment from me afterwards."
As he stared blankly at her, she let go of Kaguya's hands.
"There is your new target. Now get to work," she ordered them.
The twins looked at each other and grinned broadly. Their eyes glowed with excitement as they undressed Shido and began fondling him.
"This is gonna be fun," Kaguya whispered to her sister.
Shido did not respond. But his bulge gave enough away. The twins could feel him twitching slightly as they touched him.
"Ooh, he's getting hard already," Kaguya giggled, "he's so cute when he gets excited."
The twins continued to play with him.
"He must really like us," Yuzuru remarked.
"Look, he's starting to lose it," Yuzuru added, "I bet he'll go nuts once we get into our first position."
"Yeah, I can feel it," Kaguya replied, "he's definitely losing control."
The twins removed Shido's shirt and pants, leaving him naked except for his boxers. His cock stood proudly at attention, showing no signs of being reluctant.
"Looks like you're ready," Kaguya teased him, "let's get started."
She took Shido's hand in hers, leading him to the middle of the room as she wrapped her arms around his waist. Yuzuru quickly followed suit. Then the two sisters embraced Shido tightly as they pressed their bare breasts together. Shido groaned as he felt their soft flesh pressing against his body.
"Ohh, you two are so nice," Shido sighed, "I wish I could stay like this forever."
The twins looked at each other, wondering if they should be doing this. After a moment, though, they decided to follow their instincts.
"Let's go," Kaguya whispered, "We've got to hurry before he loses it."
Yuzuru nodded in agreement, dragging Shido towards the bed.
They had barely taken three steps when Shido suddenly stopped moving.
"What's wrong?" Kaguya asked him worriedly.
Shido didn't answer. Instead, he looked up at her pleadingly.
"Please let me cum..." he begged her.
The twins looked at him in surprise. They hadn't expected this.
"Get moving," Kotori commanded him.
Shido looked at her desperately. His pleas fell on deaf ears.
"No," She replied firmly, "if you cum now, we'll never get to do anything else tonight."
"Fine," Shido insisted stubbornly, "but I promise you'll regret it."
Kotori knew that she couldn't win this battle. She reluctantly agreed and led him to a chair.
The twins watched as Kotori guided him and then knelt next to them.
"Are you sure about this?" Yuzuru asked.
Kotori paused and thought for a moment before answering.
"Yes," she finally told them. "He won't do it unless you take control like this."
The twin sisters nodded eagerly.
"Let's give him what he wants," Kaguya said.
She grabbed Shido's dick and began jerking him off while her sister rubbed his balls, and Kotori kissed his thigh.
"You want me to make you cum, don't you?" Kaguya taunted him.
"Yes," Shido whimpered.
"Then look at me," she commanded him.
Shido opened his eyes and fixed his gaze on her.
"Look at me," she repeated, "so I know you're listening."
Shido continued looking at her.
"Now, do you want to cum? Do you still want my sister to make you cum?"
Shido nodded fervently.
"Good," Kaguya said, "because I'm going to make you cum... right now."
She grasped Shido's member and began stroking him slowly. As Yuzuru moved behind him, leaning over his body and kissing him passionately.
Shido gasped as Kotori and Kaguya's hands slid up and down his shaft, sending waves of pleasure through him. His muscles tensed as he fought to contain his excitement.
"Ohhh... I love how your skin feels under mine," Kaguya cooed to him.
Yuzuru grabbed his head and began licking his neck. She traced it up to his mouth, forcing her way in. Her tongue was rough and tasted salty, but the taste only aroused him more.
Suddenly, Kotori pulled her hand away from his throbbing member.
"Now!" she called out, "don't stop yet."
The twin sisters looked at her, confused.
"It's okay," she reassured them, "just keep doing what you're doing."
Shido groaned in frustration, but obeyed her. Kaguya immediately began stroking his cock again, while Yuzuru resumed her caresses.
"I see, so he's close," Yuzuru noted.
"That's good," Kaguya replied, "I can feel him straining."
Their soft touches kept Shido on the edge, and soon enough he reached his limit.
"Ohhh, I'm going to cum," he moaned, "please make me cum..."
"If you want us to help, you have to say it," Kotori reminded him.
"I want to cum!" Shido cried.
"Cum for us," Kotori ordered.
Shido looked at her pleadingly.
"Come on," she encouraged him, "say it."
"I want you to make me cum!" Shido shouted.
The twin sisters smiled happily.
"Very well," Kotori declared, standing up.
With that, she leaned down and kissed him deeply, pressing her body against his.
Shido reacted quickly. He wrapped his arms around her waist and pulled her close, running his fingers through her hair. As he did, Kaguya took his dick into her mouth and began sucking him off. Meanwhile, Yuzuru reached down between his legs and began rubbing the base of his shaft. Soon enough, the combination of their hopeful touch sent Shido over the edge.
"Ahhhh! Ahhhhhh!!" he yelled loudly.
A powerful spurt shot out of his shaft, splashing across the twin's faces.
"Mmmmmm!!!" Kaguya exclaimed as he ejaculated inside her mouth.
Yuzuru giggled and continued to rub the base.
Kaguya swallowed his load greedily, as Kotori knelt beside her. With a grin, she forced her kiss onto Kaguya.
"Mm-hmm," she purred contentedly, "you taste so good."
After several seconds, she spat out the last few drops and licked her lips clean.
"Good girl," she praised Kaguya.
Meanwhile, Yuzuru had removed her hand from Shido's groin and was moving closer to his face.
"Don't just lie there," she instructed him, "come closer."
Shido complied.
"Okay, now look at me," she ordered him.
He obeyed and looked directly into her eyes.
"Now, tell me what you see," she demanded.
Shido gulped nervously.
"Um... umm... what do you see?" he stammered.
"Hmm...nothing. That's what you are, Shido. You're not the kind of man who can defeat me. So I'm going to show you how weak you really are, and then I'm going to break your spirit."
Shido whimpered, looking over at Kotori.
Yuzuru pulled his head back towards her. "I'll beat you until there is nothing left of you—no memories, no feelings, not even the will to fight back. And when I've finished breaking you, I'll make you mine."
"And then I'll fuck you, and you'll cum for me. Do you understand?"
Shido shook his head.
"Of course you don't," she laughed, "you're a boy, after all. But that doesn't matter."
She smiled at him, "Now get on your hands and knees," Yuzuru instructed him.
Shido did as he was told.
Without another word, she sank her teeth into his neck and bit down hard.
"Aaarrrgh!" he screamed in pain.
"Shut up!" she snapped.
Her teeth drew blood, and Shido squirmed in agony.
"You're mine now," she announced.
She released her grip on his neck and ran her tongue all around his wound.
"That's right," she whispered, "this is my mark. From this point forward, you belong to me."
