Considering Natsuha's body was already at its limit, Jin decided not to break her completely... for today.
But the little joke of sucking him off while he was talking to his little sister deserved a correction.
So, before finishing, he bent her over the desk and left her ass red with brutal spanks, branding her cheeks with his handprint.
Only after leaving her whimpering and with her ass cheeks burning did Jin bury himself in her one last time and empty his balls completely inside her, filling her with milk until she overflowed.
The punishment was over.
...
Half an hour later, in the bathroom.
Hot steam filled the room, fogging up the mirrors.
Jin was sitting inside the large bathtub, with the hot water covering him to his waist, and Natsuha, totally exhausted and without the strength to move on her own, lay resting on his chest, between his legs.
The water was murky, mixed with soap and the fluids coming off both of them.
Taking the bottle of shower gel, Jin poured a generous amount into his palm and rubbed until he made a thick lather, then with possessive movements, he started cleaning her body.
He ran his soapy hands over Natsuha's belly, cleaning the sweat stains, and went down to her crotch, washing her reddened lips with extreme care.
Then he moved his hands up.
"I'll never get tired of them..." he murmured grabbing her gigantic tits and soaping them up.
Natsuha's udders floated in the water and he massaged them with the excuse of cleaning them, running his thumbs over her sensitive nipples that hardened instantly.
Plap
"Turn around," he whispered in her ear, slapping her tit.
And docile as a house kitten, Natsuha turned her body clumsily in the water.
She extended her arms and hugged Jin around the neck, burying her face in his sculpted pecs, rubbing her slippery breasts against him.
Looking up, she looked at Jin, who was washing the soap off her back with a gentleness that contrasted with the brutality from a while ago.
Her heart melted.
She thought that Jin, in the rush he was in to get back home, would simply leave her lying on the bed after fucking her. But no. He was bathing her and taking care of her.
This mix of domination and care made her feel a wave of sickly love.
"Jin-kun... you're too good to me..." she whispered, pressing closer to his body, "I thought you would leave and leave me alone... I feel like I'm the happiest woman in the world right now."
While sliding his soapy hands down her smooth back, Jin brought a hand up to her face and grabbed her chin firmly, forcing her to look at him, while running his thumb over Natsuha's fleshy lips.
"You have a very sweet mouth..." he whispered with a smile, "And very talented."
Natsuha blushed, but licked Jin's finger boldly.
After making sure she was spotless, he started cleaning himself.
He had to get the smell off before going back home.
Natsuha, recovering a little strength in her arms although her legs were still jelly, insisted on helping him.
With devotion, she took the sponge and scrubbed Jin's pecs. Then, her small, soapy hands went down with shyness but fascination toward his crotch.
She carefully washed the cock that had impaled her so brutally, which was now resting heavy and asleep between his legs, cleaning off the remaining residue.
It was an act of domestic submission that Jin loved.
When they finished, he emptied the dirty water from the tub and turned on the shower to give them a final rinse, washing away any trace of soap.
Stepping out of the water dripping wet, he wrapped Natsuha's naked and trembling body in a towel.
Lifting her into his arms without letting her touch the floor, Natsuha clung to his neck, feeling protected in the arms of her love.
He walked to the bed and laid her carefully on the mattress.
He covered her up to her neck, hiding the map of hickeys and bite marks that now decorated her skin.
He leaned over her and gave her a gentle kiss on the forehead.
"Rest, Natsuha. Recover quickly... because next time I won't be so nice."
"Yes, Jin-kun... ♥️"
Natsuha closed her eyes with a smile of total happiness.
...
By the time he arrived, the sun had already completely set and the sky was a closed black blanket.
More than two hours had passed since classes ended and Jin felt a twinge of guilt.
He had originally agreed with Yuna that he would be home at six o'clock sharp for dinner, but his intense "private tutoring" session with Natsuha had dragged on much longer than planned.
He stopped in front of his front door, feeling slightly uneasy, and took out his key.
But he barely had time, as he hadn't even taken a step inside when a familiar voice greeted him abruptly.
"Welcome home, Jin-kun~!"
Swish
A figure lunged at him.
Quickly, Jin caught her in his arms. It was Yuna, looking at him with her face lit up by a radiant smile of happiness.
"I'm home, Yuna..." he replied returning the smile, trying to act naturally.
"Welcome back, little Jin!"
"Jin-kun, you're here!"
From inside, the voices of Mira and Nina also arrived.
Quickly taking off his shoes in the entryway, he put on his slippers.
And Yuna didn't leave his side, walking behind him, practically vibrating with joy to have him back.
But noticing that he was still carrying weight, she stepped forward with an affectionate gesture.
"Let me help you with that," she said, gently sliding the backpack off his shoulders to set it aside, acting like a perfect wife welcoming her husband.
"Thanks, Yuna..."
Upon entering the living room, he saw that Nina was already sitting at the table. She had taken off the blue school uniform from the morning and was now wearing a loose red t-shirt, which gave her a much more relaxed and homely air.
Mira, in her pale yellow apron, moved gracefully back and forth between the kitchen and the dining room, bringing bowl after bowl of steaming food that filled the air with a delicious aroma.
Seeing her so busy, Jin rolled up his sleeves and rushed to help carry the last few dishes.
With his help, the table was ready in a minute.
Stopping, Mira wiped her hands on her apron and looked at him with a pout and a tone of affectionate reproach.
"Why are you so late, Mr. Busy~? I had to reheat dinner and it was almost getting cold again."
Jin scratched the back of his neck, feeling genuinely guilty.
"I'm really sorry. I lost track of time…"
Seeing his repentant puppy face, Mira's expression melted instantly and approaching him, she gently pinched his cheek.
"It's okay, it's okay, don't make that face. The important thing is you're home now, little Jin~."
Then she went back to her seat at the head of the table and looked at Yuna and Nina, who were waiting patiently with chopsticks in hand.
"Come on, let's all eat."
"Itadakimasu!"
Jin picked up his bowl and started enjoying Mira's cooking.
He didn't know if she had some kind of sixth sense or if it was just a cosmic coincidence, but tonight's dinner seemed specifically designed to recharge... male energies. The table was full of potent seafood: abalone, raw oysters, scallops...
Taking a fresh oyster. The meat was soft and tender, and upon biting it, it released an abundant and salty juice that flooded his palate.
The slippery and wet texture brought back memories...
He ate several in a row voraciously.
He had to admit that, between the hunger and the properties of the food, he felt the heat rush straight to his head, reactivating his body.
…
Dinner passed between light chatter and the sound of silverware.
Yuna, always full of energy, led the conversation telling funny anecdotes about what had happened on campus, while Nina chimed in from time to time to add a detail or correct her with a smile.
Mira didn't say much, she simply ate slowly and watched them with that soft, maternal look, silently enjoying seeing the three of them gathered in front of her.
For anyone seeing Yuna at home, so vivacious, giggly, and always looking for any excuse to cling to Jin, it would be impossible to imagine what she was actually like outside these four walls.
On the street, she was the total opposite: extremely shy and reserved with strangers.
She projected that unattainable and distant aura that intimidated most men.
According to what Nina had told him, Yuna was so popular at her university that she even had an unofficial fan club, although she probably didn't even realize it.
Nina, on the other hand, was the opposite case.
Although on the outside she projected that image of a quiet and somewhat distant girl, in reality she was very social. She was athletic, had a ton of friends, and was good at sports.
Besides, she was an academic genius, she was so smart that, ironically, she often ended up helping her older sister, Yuna, with her university assignments.
"..."
Jin looked at them.
Even though they didn't share blood ties, the three of them treated him as if he were their real family, taking care of every detail of his life with absolute dedication.
Remembering everything, warmth enveloped him and a deep pang struck his chest.
This peace was the real reason why he strove so hard to become strong!
With dinner finished and stomachs full, Yuna got up to help her mother wash the dishes.
Meanwhile, Jin and Nina took the chance to go to the living room to rest a bit. She turned on the TV and left a nature documentary on that served as background noise.
She settled into a corner of the sofa, pulling her legs up and hugging them.
But her attention wasn't on the screen.
Jin felt her eyes locked on his side profile, with a vacant, hypnotized gaze, as if she were trying to decipher something.
He snapped his head around.
"Is something wrong, Nina?"
Their gazes clashed for a second, catching her totally off guard.
"N-Nothing…"
Startled, Nina looked down instantly, playing nervously with a lock of her hair. "I was just thinking... how are you doing with your studies lately?"
"Pretty good, actually... I'm sure I'm going to get a top score on the entrance exams!" Jin replied with absolute confidence.
He wasn't exaggerating.
The entrance exams were divided into two parts: theory and actual combat.
In combat, he knew he had no rival. And as for the theory, after killing himself studying these past few weeks, he felt he had everything under control.
It was a guaranteed victory.
"Mm, that's good..." she murmured under her breath, not stopping twirling the ends of her hair around her fingers.
Laughter from Yuna and Mira drifted in from the kitchen, mixed with the clinking of dishes being washed.
But in the living room, the air felt awkward, charged with a strange static.
The only thing filling the silence between them was the monotone voice of the documentary narrator.
Jin ran a hand through his hair, frustrated.
It didn't make any sense!
When he first got to this house, Nina was his shadow, she loved being glued to him... even more than Yuna!
But he didn't know exactly when things had changed...
Lately, whenever they were alone, she'd put up this invisible wall and get distant.
Only when the three of them were together did that cheerful, giggly Nina he loved reappear.
'Must be a puberty thing...' he sighed.
Just then, Yuna and Mira came out of the kitchen.
"Hehe~"
Wearing a mischievous little smile on her face, Yuna didn't waste any time.
She headed to the sofa and plopped down next to Jin. But she didn't just sit, she practically melted onto him.
With a palpable need for contact, she pressed against his side, rubbing her shoulder and arm against his with affectionate movements, invading his space as if it were the most natural thing in the world.
From her corner, Nina's eyes drifted toward them.
"..."
Seeing her sister glued to him like that, she felt a pang and unconsciously bit her lip hard, looking down so her lashes would hide the glint of jealousy and frustration that flashed in her eyes.
"Oh..."
Mira, who had caught it all with a single glance, sighed.
'When is this girl going to realize her own feelings?' she thought, watching her with a mix of pity and tenderness. 'She needs to wake up. On the battlefield of love, if you hesitate for a second and fall behind... you might never catch up to them.'
