Feeling Tanjiro's hot breath on her private parts, Nezuko's racing heart nearly leaped out of her mouth.
'Onii-chan… Why, why does it feel so g-good~' Being touched there, even though it was just a graze, had sent her to cloud nine. Jolts of pleasure rushed to her head.
"Mhm…" Almost instantly, her body reacted by releasing drops of viscous fluid from her closed vagina, drenching it even further. Her back arched and she lost her strength, leaning backward and resting against the wall.
The grip of her legs on her brother's head loosened as she basked in the sensation.
Nezuko looked at her brother's eyes pleadingly and mumbled in a soft, honest tone. "It f-feels so… good… Onii-chann…" From the hazy look in her eyes, she was clearly craving more.
Taking in her rich scent involuntarily because of being pressed against her dripping folds, a fully concentrated Tanjiro noticed that despite the small orgasm his sister had just experienced, no notification from the system had appeared.
That meant only one thing from what he could tell.
Nezuko desired more.
Therefore, he must continue until she was completely satisfied.
"Relax. Just leave everything to your brother." He spoke in his calm voice, reassuring her.
She gave a soft hum, feeling light-headed.
Receiving Nezuko's permission, Tanjiro sensed the whole mansion using all his power and made sure nobody was coming to the second floor. He would rather postpone it to another day than risk everything because of carelessness.
'If someone comes, I'll postpone it to another day…' Deciding that, he refocused on the meal before him while keeping his five senses active.
Taking deep breaths, Nezuko's erotic smell swirled in his mind, etching itself into his powerful memory.
'Mother's scent is richer…' He couldn't help but compare. His sense of smell was just too sensitive, so the realization came naturally. With Kie being an adult over thirty who had given birth six times, her vagina was definitely more mature than young Nezuko's.
The color and shape were different too. While Kie's pussy was hairy and had more texture, Nezuko's vagina was hairless and had a smooth texture. Her labia closed her pure vagina so perfectly that it looked more like a pink line drawn on her vulva than a genuine pussy.
Gulping down the excessive saliva, Tanjiro prayed inwardly, 'Well then, I humbly receive,' before digging in to enjoy the feast.
The tip of his tongue came out and gave Nezuko's vagina a gentle lick from bottom to top.
"Mm~" Nezuko's body shuddered. A rush of sensation surged into her mind.
Her hand on her twitching mouth tightened immediately.
But just as she did, more powerful pleasure shot through her spine, causing her to feel something she had never experienced in her entire life.
'Onii-chaannn… Licking dirtyy p-place… Why, why… feels s-oo gooddd–!' Her brain started to discard everything except the euphoria flooding her body and soul.
"Anh~" she moaned softly as Tanjiro's tongue began to lick her sensitive places with even more intensity. "Onii-chan~"
Her developing chest heaved up and down continuously while her legs convulsed in ecstasy.
Using both hands, she did her best to keep her voices from leaking out, no matter how much she craved to moan as loudly as she could.
Tanjiro's hands gripped Nezuko's thighs, caressing her soft, milky flesh affectionately. The sensation of her tender skin felt far better than he expected. Gently squeezing and massaging her thighs, he relished the comforting touch.
Despite losing her strength, her legs were still shaking. Tanjiro held them in place on his shoulders and sucked on her fleshy labia with everything he had. As her big brother, it was his duty to make sure Nezuko was clean and serene. He must do whatever it took to fulfill her desires so she could grow up healthy.
"Hu… Ha… Onii…" Nezuko's eyes moistened as she felt a strange sensation rising near her crotch.
Tanjiro, busy licking and sucking her twitching vagina, locked eyes with Nezuko and easily understood her thoughts.
"S-something's… coming, Mm…" she said with great difficulty, a single tear slipping from her eye.
She raised her butt instinctively, trying to rub her vagina in tandem with her brother's tongue.
The mind-melting pleasure was building slowly, she finally realized.
Something was going to erupt… Nezuko could sense it.
Feeling her throbbing cunt through his lips and tongue, Tanjiro decided to give her a final touch.
With his thumbs, he stretched and parted her labia slowly, revealing her young, pink pussy before his eyes. Her small clitoris was immediately caught by his fast-moving tongue, teasing it continuously.
The faster he worked, the more strongly her pussy twitched in response.
"Anh, Onii-chan~" At some point, the strength in Nezuko's legs returned for a moment and she wrapped them around Tanjiro's head, pushing him deeper into her crotch.
Her flushed face twisted strangely as her back jolted upward, breathing growing erratic. Her eyes narrowed in overwhelming lust as she gave in to the unstoppable pleasure.
"HNGH~" her muffled voice leaked out despite her best efforts.
Tanjiro's mouth latched onto her pussy as he devoured her gushing juices with devotion. His throat bobbed for seconds while he continued to gulp down whatever her pussy released. His eyes were calm and there was no hesitation.
It was his sister's first real orgasm; there was no way he would let it go to waste on the floor.
Being pressed by Nezuko's legs felt more like having his head placed between two cushions. It was extremely cozy for Tanjiro, to be honest. If possible, he would stay there forever.
Remaining in the same position for a few seconds, both brother and sister didn't want to let go.
Only when some clarity returned to Nezuko's mind did she shift her body. Though there was no strength left in her. Her heart was still beating loudly. Her pussy was pulsating from the earlier release. Her flesh had grown a shade of red near the crotch as her stomach heaved from the powerful sensation. Her spine was twitching even now, her nerves tingling all over her body. Toes curled up, neck flushed, she mumbled one last word before she blacked out tiredly. "Onii…chan—"
The instant she fell asleep, Tanjiro moved and lifted her in his arms.
Licking the leftover fluids from his lips, he looked at Nezuko's satisfied face and smiled inwardly.
A transparent screen popped up next to his face.
[Mission completed!]
[You may claim your reward now] [Claim]
One mission was already completed within minutes. The other might take years.
Not giving it another glance, he placed his sleeping sister on the bed first. Next, he took out a dry cloth from his drawer and wiped his sister's pussy clean thoroughly. As he did, Nezuko's body responded to his touch by slowly moving in a cute manner.
Seeing such a scene, Tanjiro chuckled. 'She's such a sensitive bunny… Ah.'
Placing his hand over his heart, he noticed it was beating abnormally.
A faint smile appeared on his face. Fixing her clothes and settling her body comfortably, head under the pillow, he crouched next to her and whispered into her ear softly. "Nezuko is Onii-chan's belonging. Got it?"
Placing a kiss on her forehead, he touched her cheeks fondly.
The memories of Nezuko played in his mind.
How they used to play together without any worry. How they took care of each other when one of them fell sick. How they used to bathe together when they were just little kids. How gently he had treated his sister like she was the most precious treasure of his life. So many memories, all of them reappeared in his mind, flowing like a stream.
Staring at the sky through the window, Tanjiro didn't realize that his fingers were already locked with Nezuko's.
Releasing a deep breath, he came out of his trance.
Knock. Knock.
'Hmm?' His pupils moved to the wooden container at the corner. 'Mother…'
Removing his fingers, he closed the window and stretched the cover to block the sunlight. The light disappeared from the room.
The container was pushed open, and out came his demon mother with an expressionless face, her body similar to that of Hanako. As a demon, she could change her body size, so that wasn't surprising.
As soon as Kie located Tanjiro nearby, she made a pout and pounced herself into his arms.
'Eh… Don't tell me, she's jealous?' He figured out, brows raised.
Looking at her son's face with her demonic eyes, she purred. "Kiss…"
Though she said that, the next second she lunged her head forward and caught his lips with urgency.
It was torture sensing her son doing the same thing for someone else.
He was her child, hers!
Everything of his belonged to only her!
Nobody else was permitted to take advantage of her child!
Kissing him desperately, Kie moved her tongue into his mouth and relished in the sensation.
Tanjiro let her do what she wanted.
Feeling her love so clearly, he groped her ass and started to kiss her back.
He seated himself beside her container, wrapped her small body against his, and let himself be drowned by his mother's love.
'One after another… This is indeed the lucky day.' He thought, eyes closed in overwhelming pleasure.
