"Tighten up, girl!" Yoongi hissed unhappily, and Hoseok looked back at Kara, who was squatting on her knee and fingers outstretched on the ground.

Her sparring partner grinned triumphantly and stepped up against her, she pushed hard, thrusting her shoulder into his stomach. The man flew away, squirming, defeated by his own strength.

Kara fell to her knees wearily, her eyes fixed viciously on the fallen man, her teeth chattering. They had been training for five hours and her body was starting to tingle, but Yoongi didn't seem to want to stop.

Her anger began to rage even harder, she stood up, but swayed, and Hoseok signaled to his own opponent to stop for a moment, heading for her. But Yoongi blocked his way.

Her partner took advantage of her momentary weakness and strengthened again. His fist hit her chin and then her belly, and she swayed even more, stepping back.

"Let me go!" Hoseok fought Yoongi. "No, this is her battle, it's not over yet!" Hoseok growled angrily and tried to push him away, staring at the drops of blood running from Kara's lips.

"You don't have to help her, Hoseok! Look and believe in her, my sister is not so weak!" Yoongi hissed, and Hoseok clenched his jaw as she watched Kara blush, her breathing quicken, and her body tensed visibly, stretching every possible muscle.

"I can't ..." Hoseok paused, and the two men followed Kara, who leaned forward slightly, ready to face the next blow, her rapid breathing calmed, her face returned to color and she smirked.

Her opponent missed the moment to escape, he attacked her, trying to wrap his arms around her, but she went under them, stepped on his bent knee, hers slammed into the sides of his ribs and she stepped securely on the ground behind him, punching on the other side of his body.

The man fell to his knees and leaned on his hands, breathing heavily and dizzy with pain. Kara growled viciously, bent down and grabbed his chin and nape. She turned his head abruptly, and a deafening crack of bone echoed in the quiet hall, followed by the sound of the lifeless body sliding.

Hoseok sighed with relief, and Yoongi grinned proudly, folding his arms across his chest. "This is my girl!" he praised her and she smiled wearily.

"It's your turn, Hobi!" Yoongi ordered. Hoseok raised an eyebrow, turned to his opponent, who had sensed Yoongi's signal, and was already stepping up against Hoseok.

Hoseok straightened and his fingers dug into the man's throat, which clung desperately to his wrist, struggling for air. Hoseok felt the gentle touch on his back, Kara's arm slid around his neck, and he looked down at her, continuing to choke the relentlessly struggling man.

His other hand slid and wrapped around her waist, lifting her slightly, their lips merging and his body burning, feeling her tongue examining his mouth and fighting his.

Yoongi watched the scene silently, noting the relationship between the two. His sister's limp body hung calmly on Hoseok's arm, the pleasure written on their faces as they deepened their kiss.

The tension in Hoseok's body seemed to go away, but the veins in his arm, which was suffocating the man, bulged, and if Yoongi stared, he could see their pulsation.

Kara moaned. Her body pressed against Hoseok, and he growled and squeezed the man's throat, taking away his last hope of survival. Hoseok released his opponent as soon as his fight subsided and picked up Kara, wrapping her legs around his waist.

Yoongi's eyes widened in horror and amazement. "They wouldn't ... Not in front of me!" he thought, but he was clearly wrong.

Hoseok took a few steps without interrupting the kiss and Kara's back hit the ropes in the ring, she dropped her feet to the ground, only to jump over them. Hoseok followed, jumping over the ropes with the ease of a cat, and their bodies and lips intertwined again.

"You know I'm still here, don't you?" Yoongi shouted, but neither of them answered, and he began to back away, still hoping they would realize and stop. His hope quickly evaporated as Kara tore Hobi's T-shirt and tossed it aside as he pulled her to her knees and then pressed her back to the hard floor.

"You're crazy, totally crazy! Both of you!" Yoongi shook his head and jumped out of the hall, putting two on duty so that no one would enter, who would lose his life just because he had unknowingly interrupted them.

Hoseok took off her sports bra and his hands wrapped around her breasts, massaging her nipples between his fingers. She rose to her elbows so as not to break the kiss and sat on his lap, wrapping her arms around his torso.

Maddened by the passion aroused by the two murders, the two clung eagerly to the other, drinking relentlessly, their hands marking their bodies, their lips and tongues fighting for supremacy.

Kara left bloody nail marks on his shoulders, biceps, and back, his fingers tracing her body with their reddish-blue marks, his teeth and lips digging into every spot given to him, leaving dark purple suckers.

Their tongues absorbed the taste of the salty sweat from their bodies, Hoseok pressed her to the floor again and took off her short sports leggings along with her underwear, burying his head between her legs.

Kara screamed and writhed painfully as his tongue slammed into the folds of her pussy and licked the dripping moisture.

Her fingers dug into his wet hair, her thighs rose on either side of his head, and her body shook with pleasure.

Hoseok smirked and bit her clit, sucking hard. She groaned loudly and her back twisted. He looked up at her and sucked again, inserting two fingers into her pussy, irritating her trembling walls, enjoying the wet slapping sounds.

Sensing her approaching orgasm, he pulled away abruptly, and she cried unhappily, looking up at him.

Hoseok took off his pants and she stared at the proudly raised head of his hard throbbing cock. His veins bulged almost painfully and she looked at him invitingly, holding out her hands to him.

"Not yet, my savage!" he took her hands and pulled her hard, bringing her to her knees. He stood up, and she looked up with an arrogant smile before opening her mouth and taking his cock to the base.

Hoseok wrapped his arms around her head and began to fuck her deep in the throat. Her eyes filled with tears under the pressure of the huge force with which his cock entered her mouth, but instead of pulling away, she dug her nails into his ass and tried to pull him even harder.

In the same way, just before he ended up in her throat, Hoseok stepped back, fell to his knees, and, embracing her waist, turned her back to him, pressing her shoulders.

She stood on all fours and looked back, Hoseok grinning and thrusting his cock deep into the core of her pussy. Kara shook her head with a shout, and her body tensed to withstand the relentlessly swift, rough thrusts of the man behind her.

Pulling her hips, Hoseok fucked her mercilessly, thrusting his cock so deep that Kara lost sight of the reality lost in the vortex of several successive orgasms.

Without stopping to fuck her, he bent down, cupped her breasts and straightened her, her back hitting his chest, and she began to rise and fall against his thrusts.

A new orgasm shook her body, her nails ripping his thighs, and Hoseok slammed hard into her, riding his own orgasm as his cum filled and mingled with her moisture, flowing between their fused bodies.

Out of breath, the two fell heavily on the carpet, and Hoseok hugged her to him, giving her his warmth. She shrank and looked back, receiving a passionate kiss that took her breath away.

"You did great today, my love," he buried his face in her neck and she rubbed against it. "Did you doubt it?" Kara moaned as he bit her ear.

"I'm sorry, I can't help it when it comes to you." he apologized softly and she intertwined their fingers. "I love you too, mi amore."

"They both really need treatment!" Yoongi sighed and rubbed his forehead. Namjoon laughed and leaned back comfortably.

"It's hardly that bad!" exclaimed Jin, and Yoongi looked at him like he was crazy. "They almost fucked in front of my eyes after killing their opponents!" Yoongi roared and Namjoon fainted with laughter.

"Come on! They're young, in love ..." Jin began to excuse them. "They are crazy, ruthless and have no brakes!" Yoongi shook his head, realizing he was talking about his sister and one of his best friends.

"So they look like similarities. And don't forget that you're training Kara, what else do you expect?" Namjoon asked with a smile. "That's right, but I don't think I want much, I don't need to see someone fuck my sister, even if he's her fiancé!" exclaimed Yoongi indignantly, and Jin and Namjoon burst out laughing.

"We understand, you don't accept that your little sister is already a big girl." Yoongi frowned and they both laughed again.

"However, the two must be very careful. I have heard rumors that an attack is being prepared. The news of their engagement has caused a great deal of confusion and the other families are worried about this union." Jin sighed.

"I know. Hoseok has already taken action, Kara is smart, aware of what their marriage will lead to, and more obedient than ever." Yoongi also leaned back comfortably.

"Is that why you came home so fast?" Yoongi asked, and Namjoon nodded. "The families are uniting, hoping to defeat the Min-Jung alliance." Jin explained.

"It's not unexpected. But I'm glad we can count on your help, too." he smiled and the two Kim brothers winked at him. "We owe you a lot, nothing is enough to pay this debt. Of course you can count on us, besides, Kara is also like our little sister, we won't let anyone touch her and not pay!" Namjoon smiled.

"After the tournament, everything should calm down, I hope," Yoongi frowned thoughtfully. "If Kara and Hoseok win, which I don't really doubt, there will be a war, you know that." Yoongi nodded.

"I know that to declare them King and Queen of the Mafia, and with the power of both families, they will effectively control the underworld. And my sister is, to put it mildly, unpredictable." Yoongi looked at the two brothers, who responded thoughtfully to his gaze.

"Jung Hoseok should not be underestimated either." Jin recalled and his brother nodded. "And now even more." Yoongi added, and they both looked at him questioningly.

"You'll find out tonight what I mean when you see them together at J'adore. Hoseok is completely different around my sister, which makes him even more ruthless. He just strangled a man while they were kissing like it's not tomorrow!" he shuddered at the memory of how the two had not been moved at all by his presence.

"In what sense different?" Jin leaned forward curiously. "Oh, I won't spoil the surprise!" Yoongi smiled mysteriously...
