It had been two years since the siblings started their journey, and it felt like it had been just that long since either of them had gotten time for some actual quiet. After Nezuko finally could remove her muzzle, remembering who she was before being turned, Tanjiro did his best to help his sister regain the speech she had lost during the 2-year silence. Nezuko was more than grateful for her big brother!
As of right now, Nezuko sat on the porch of an abandoned home in a forest that they had found. It almost reminded her of their family home. Nezuko smiled as she looked up at the stars, for a rare change, the sky was clear enough that she could count the lights that dotted the dark blue scene.
Nezuko closed her eyes and listened to the faint sounds of the night, it was definitely a nice change from what they were used to after all this time. There was no feeling of impending danger, just the sound of the calm breeze and soft sniffling behind-
Sniffling?
Nezuko turned her head to see Tanjiro sitting up, head in his hands. His shoulders shake as quiet sounds escape him, well quiet to anyone else.
To Nezuko they were loud and clear. It hurt her heart to see her brother like that.
The younger girl rushed to her brother and immediately planted herself into his side, causing him to yelp and look down “N-nezuko?” He stuttered, trying his best to hide his tears. Nezuko looked at him with a pout, hugging into his side silently, Tanjiro smiled at his sister, returning the hug “Hey, I’m okay.” he tried to say in a reassuring tone, but all he got was a gentle glare from his precious Nezuko; she could tell her big brother wasn’t okay, though she didn’t seem to push just what had made him wake up with such a start
Nezuko pulled away from her brother and moved to sit behind him, Tanjiro raised a brow at his little sister before a blush spread across his face as he saw Nezuko pat her lap with a smile “Lay down.” She simply said, her voice soft and sweet and damn, how much he missed her voice.
Tanjiro sighed softly before laying his head on her lap, looking up at her soft smiling face.
Nezuko softly hummed as her pinky finger gently rubbed down her brother's nose, humming a tune that their mother once sang to them. Tanjiro closed his eyes as his breathing began to settle and he fell back into a calm sleep, looking more peaceful than he had in a while.
Nezuko didn’t stop the motions as her brother slept, having her brother’s head on her lap just felt right to her. The girl hummed softly, her other hand moving to pet his head gently, fingers slowly running through his hair as she looked down at Tanjiro’s peaceful face.
“You’re such a good big brother.”
The words weren’t thought of before she said them, but her brother deserved some praise, especially for what he had been through just to make sure that she got through each day as unharmed as possible.
Tanjiro’s face scrunched cutely like he was reacting to the praise she was giving him. Nezuko felt her chest swell with pride at her brother’s reaction; maybe the praise could keep him relaxed. She was certainly going to try!
“You’re amazing Tanjiro.”
“So brave.”
“You always take such good care of me.”
Nezuko continued to softly praise her brother, her hands moving from his head to gently rubbing along his neck and shoulders.
Nezuko wasn’t entirely sure if the praise was keeping her brother relaxed, his breathing was slightly ragged, and he was making soft noises that she knew should feel wrong as she felt her core grow hot.
The feeling wasn’t new to her, Nezuko often had periods throughout the month where she would feel her body burn and ache for something she wasn’t entirely sure of. Other demons could smell it sometimes and it often led them to her, though she wasn’t entirely sure why yet.
She moved Tanjiro’s head off her lap, leaning closer to his ear “Such a good boy.” She whispered, kissing his cheek.
Tanjiro’s whole body tensed and a soft gasp escaped him, Nezuko flinched back as she looked over her brother, Tanjiro panting gently as his face was slowly turning red. Nezuko tilted her head, before noticing a bump rise underneath the blanket.
Slowly, Nezuko removed the blanket and her eyes widened as it finally clicked; Tanjiro was getting turned on by the praise.
Nezuko bit her lip as she looked over the still-hidden member, trying to stop her mouth from watering and resisting the urge to release his cock from its confines. Surely this is wrong? Why would she want to taste her brother? To feel him fill her out as he paints her insides white…
Nezuko shook her head, covering her mouth to quiet a soft noise as she squeezed her eyes shut, turning her head away. Tanjiro wouldn’t want her to!
They were siblings!
They were underage!
Tanjiro was sleeping !!
Nezuko looked towards the cock again, gulping as she felt an urge rise inside of her.
Nezuko couldn’t exactly leave Tanjiro like this, plus he deserved a reward for how much he takes care of her.
This would just be her returning the favour!
Nezuko moved between Tanjiro’s legs, undoing the white robe and slowly pulling his black pants enough for his cock to spring out. Nezuko looked up at Tanjiro again.
Still sleeping, his breathing at a steady pace.
Nezuko bit her lip as she started to slowly pump his cock, watching as her big brother’s breathing slowly picked up.
Her jerking slowly picked up as she kitten-licked the head, swiping over the slit as pre-cum already started to drip from the tip, softly humming as Tanjiro’s hips bucked against her warm mouth.
Nezuko smiled as she got a delicious idea “Such a good boy, big brother.” Tanjiro’s cock twitched in her hand in approval. Nezuko smiled as she felt some pride at getting a reaction, even if it was a small one.
Nezuko took a deep breath and looked at her sleeping brother one more time before giving a long lick from the base to the tip, wrapping her lips around the tip, and swirling her tongue around the leaking head.
Tanjiro whimpered in his sleep, feeling his body heating up in a way that embarrassed him. Tanjiro felt a familiar knot in his stomach, but the unfamiliar feeling of someone licking along his cock urged him awake, opening his eyes, and sitting up on the futon. He was shocked to see Nezuko sucking him off, the feeling of her tongue swirling around him was almost too dizzying
“Ne-Nezuko..” he moaned, biting his lip hard enough to almost draw blood as Nezuko looked up at him through her lashes, she pulled off his cock with a slight pop , saliva connecting her lips to him.
Fuck that was doing things to him it shouldn’t.
“W-what are you…” Tanjiro stuttered, unable to get the question out, his throat felt like it was closed tight. Nezuko only smiled up at him, her hand jerking what was just in his younger sister's mouth “I’m rewarding you, big brother.” She answered as if it was the most obvious thing in the world.
Tanjiro’s face must have twisted into confusion, cause Nezuko only giggled “You're always a good boy!”
Tanjiro felt his eyes go wide and his mouth go dry. His heart started racing as he stared at Nezuko in disbelief “What did you say?”
“ Good…”
Nezuko leaned her face closer to Tanjiro’s cock
“Boy.”
His cock was once again swallowed by the hot mouth of his younger sister, Tanjiro threw his head back as he moaned. Panting, he watched as Nezuko set a slow pace as she focused on the tip, her tongue teasing the slit as she swallowed any pre-cum that dripped into her mouth.
Tanjiro covered his mouth with his hand, holding back any noises that dared to come out; he shouldn’t be enjoying this, this was his younger sister! She shouldn’t be able to suck cock so good.
Tanjiro let out a strained noise behind his hand as he felt Nezuko take more of his cock into her mouth, halfway down his length.
As Tanjiro was enjoying the treatment, Nezuko pulled off his cock and climbed onto his lap, unwrapping her kimono as she lined herself up over her brother's cock.
Tanjiro looked at her with wide eyes, hands going to her hips to hold her still before she could make a move to lower herself onto him “Nezuko, you don’t have to-”
“I want to!” Nezuko interrupted, her voice sounding desperate as she clung to Tanjiro’s shoulders, her eyes pleading as she stared at him “ need to! Need you!”
Tanjiro stared at Nezuko in disbelief, as if the words refused to process. Nezuko was staring at him as if she would simply stop existing if he didn't let her sit on his cock.
Tanjiro swallowed hard before nodding, letting Nezuko do what she wanted. She was always his weakness, it would be useless to try and fight her this. She had made her mind up, so Tanjiro guided Nezuko’s hips down, the siblings gasping as she sank completely down onto him. Nezuko whimpered, leaning her head against Tanjiro’s shoulder “So... full…” she breathed.
Tanjiro waited for Nezuko to make the first move, one of his hands rubbing up her side to comfort her.
After a minute, Nezuko lifted her hips before slowly lowering herself back down, she repeated this steady process and before long she was bouncing faster, panting as she rode her big brother.
“Tanjiro! Tanjiro!” She panted, losing herself as she could feel every inch sliding in and out of her wet core.
Nezuko yelped as she was flipped over staring up at Tanjiro hovering above her before he started pounding into her. Nezuko’s arms wrapped around Tanjiro, pulling him closer as he continued his assault.
“So good!”
“Right there!”
“I feel so good Big brother!”
Tanjiro groaned at the praise, lifting Nezuko’s hips a little higher to hit at a different angle, Nezuko moans became louder as the pleasure she felt became more intense, her walls tightening around Tanjiro as she clung onto him.
Nezuko’s mind became hazy as she came undone, feeling her insides burn in the best way she didn’t know was possible as Tanjiro kept thrusting inside her sensitive walls, building up his own orgasm.
“I-I’m gonna pull-”
Tanjiro made a move to pull out before he came, but Nezuko wrapped her legs around his hips and slammed him back inside, her eyes shining a brighter pink for a moment as Tanjiro came deep inside his younger sister.
Tanjiro and Nezuko lay there for a moment, tangled in each other so intimately that neither of them could have ever guessed they would have found themselves.
Eventually, Tanjiro finally pulled out and laid back on the futon, Nezuko laying her head on his chest as their legs tangled together. Tanjiro wrapped his arms around his sister, smiling as she fell asleep. He softly kissed her forehead before falling into a peaceful sleep.
