Before he could process what was happening, in the blink of an eye, Kie had already freed her full, mesmerizing breasts from her clothes and pressed them against his face.
She gazed at him with pure motherly love, gently patting his head.
"Drink… Mother's milk… Tanjiro…" she murmured softly.
Tanjiro froze.
'Did the transformation break her mind? Is my mother actually insane now?'
No.
He could feel it through his heightened senses and her pure, unmistakable scent—her emotions were genuine, overflowing with care. She wasn't crazy. She was simply treating him like her newborn baby.
Wait…
'Did the transformation lock away the last ten years of her memories? Does she think I'm still an infant?'
It clicked in seconds.
But understanding why didn't solve how the hell he was supposed to deal with this.
Right in front of his eyes was her dark-pink nipple, a faint drop of white milk beading at the tip, slowly dripping onto her robe.
'Breast milk!? She's actually lactating!?'
The sweet, intoxicating scent flooded his senses.
"Tanjiro… my child… drink…" Kie cooed, stroking the back of his head and gently pushing his face closer.
Then, like clockwork, the system panel flashed.
[𖤐 Mission: Milk Mommy for one hour]
[𖤐 Reward: Bone Tempering]
Goddamn motherfucking system…
His heart was already racing. Affection and instinct clouded his vision. All hesitation melted away.
In one swift motion, his lips closed around her nipple. He sucked hard.
Warm, sweet milk flooded his mouth.
He swallowed greedily, the rich flavor coating his tongue.
[59:14]
Kie smiled tenderly, guiding him down. She sat in seiza, laid his head on her soft lap, and leaned forward so her baby could drink freely.
Tanjiro surrendered completely. The back of his head rested on her warm thighs as he latched on again, drinking deeply.
He was drunk on her milk, the world fading away.
With his free hand he squeezed her other breast. Streams of warm milk splashed across his face, running down his cheeks.
The sweet aroma filled his nose, making his head spin.
He kept going, lost in the taste, the softness, the overwhelming warmth.
Even though something in his pants had very much woken up, he couldn't care less.
Kie simply watched him with endless love.
In her eyes, he would always be her little baby, and she would do anything to take care of him.
The breastfeeding session continued without pause.
Tanjiro's mind felt like it was melting.
The softness of her breasts, the electric jolt of her nipples, the rich, sweet flavor of her milk, the tender rhythm of her pats; everything had long since overwhelmed his senses.
Primal instinct took over completely.
His heartbeat thundered in his ears; blood surged through every vein.
The heat and warmth made his cock throb violently.
At some point, while his mouth latched onto both nipples at once, a soft hand slipped inside his pants and freed his aching erection.
Eyes closed, he was too lost in lust and craving to react.
He just kept sucking desperately, drawing more milk.
Kie tilted her head, gazing at his hardness with gentle curiosity.
She wrapped her fingers around it and began stroking with loving care.
"My… boy… Mother will… help…" she murmured, voice thick with affection.
Her hand turned upside-down and moved in slow, deliberate strokes.
"Uh…" Tanjiro finally couldn't ignore the pleasure from below and cracked his red eyes open.
He saw Kie's calm, doting gaze fixed on him, her hand pumping steadily.
The overwhelming sensation crashed through him.
He squeezed her breasts wildly; milk fountained from her nipples, soaking his face and mouth in white.
He swallowed greedily, licking her areolae and every last drop clean.
Thought was gone. Only need remained.
[12:45]
After a few more seconds, ecstasy exploded from his core. Thick streams of white shot into the air.
His mind went light as a feather.
But it wasn't enough.
The arousal didn't fade.
His cock stayed rock-hard.
Her breasts were still in his grasp, nipples still in his mouth.
'More… I want more…' the thought looped endlessly in his head.
Kie ran her fingers through his hair, noticed his erection still standing proud, and smiled with pure motherly warmth.
"Tanjiro is… such a good boy…"
She wrapped her hand around him again and resumed her gentle, rhythmic strokes.
Tanjiro's stomach was already full to bursting, yet he kept nursing like his life depended on it.
The system timer was long gone, but he never realized.
Right now, all he wanted was to be utterly spoiled under his sweet mother's care.
....
4 AM, early morning.
Long before sunrise, Tanjiro was already awake.
After last night's unforgettable events, he had only managed about two hours of sleep before Kie's tight, snuggly embrace woke him up again.
For some reason, she had mimicked his position and curled up beside him, hugging him like a newborn.
She seemed completely determined to treat him as her baby.
He wouldn't mind being spoiled like that in the future, but he absolutely had to restore his mother to her original self, no matter how tempting the alternative felt.
After getting up, he first checked on his siblings.
They were safe and sound asleep. Even Nezuko was curled up, hugging Hanako.
Seeing them like that brought an involuntary smile to his face.
The house was destroyed, but his family was alive. The disaster had been stopped. Everyone was okay.
Well… except for their mother. She was a demon now, but as long as she was breathing, there was hope. He would fix her, sooner or later.
Next, he claimed the reward.
Bone Tempering…
The process took about five minutes.
There was no pain this time, only a pleasant tingling. A cool sensation spread through his bones, strengthening and nourishing them from within.
When it finished, his stomach rumbled.
Impurities, probably...?
After taking care of that, he started a fire outside using broken wooden planks to block the wind.
The bathroom had been destroyed by Muzan, so he heated water in large drums for bathing.
Next on the list: a basket for his mother. His mind was already racing several steps ahead. Great power brought great responsibility, and he was dead serious about planning for the future.
Since Kie couldn't be exposed to sunlight, he had already sealed the small charcoal shelter completely, leaving no gap for light to enter.
Inside, Kie sat quietly in the corner, arms wrapped around herself, humming softly.
A lullaby?
"Mother…"
He recognized the melody instantly. It was the same lullaby she used to sing to him and Nezuko when they were little.
Sighing, he quickened his pace and began weaving the basket.
There was always a chance the system would offer a reward to fix her mind, but he couldn't just sit around waiting like an idiot. He had to keep moving forward.
One hour later~
The perfect sunlight-proof basket was finished.
He had washed up, changed clothes, and cooked breakfast from whatever remained in storage plus a few rabbits he hunted. It would be enough for all six of them.
Standing in the thick snow that had finally stopped falling overnight, Tanjiro stretched and smiled.
His siblings were still fast asleep.
"Hmm, they're just kids… I'll have to comfort them properly later," he murmured, turning to wake them.
But moments later, he sensed a human presence rapidly approaching their location.
Strong. Very strong for a human.
A faint smile flashed across his face.
"He's early. Butterfly effect already, huh?"
'I should greet our guest properly, shouldn't I?'
