Paying frequent visits to Shinobu's study at the butterfly mansion had become a daily thing for Tanjiro.
Especially now that his relationship with the insect hashira went a little more beyond friendship.
When Shinobu walked into her study she found Tanjiro fast asleep on the sofa, breathing softly; burgundy hair a wild disarray with his hand resting on his stomach. Pleased by his presence, she grinned and stepped closer, stealing glances at his sleeping face, trying not to laugh. He looked so cute that she wanted to pinch his cheeks but opted to bend down to press a tender kiss to his nose instead, before reaching out to stroke his cheeks with all the affection in the world.
He blinked drowsily, voice a little hoarse from sleeping when he spoke to her. "Shinobu-san, are you finished with work? I had been waiting here for you and I fell asleep."
She hummed in agreement while continuing to caress his face tenderly. "I am done, but I do feel like I could do with a little nap right now." she shyly moved to lie on top of him, thighs straddling his lap at first before she shifted till both of them felt comfortable. He slipped his arm around her waist, drawing her closer until her face was pressed against his chest. "Of course, get some rest."
Tanjiro pressed a tender kiss on her head before he closed his eyes, already falling back to sleep again. Her eyes fluttered shut, listening to his heartbeat closely before she also drifted to sleep.
She woke up a few hours later, purple eyes fluttering open drowsily, she unexpectedly found dark red eyes staring back at her. Blushing lightly, she glanced sheepishly at him, running her gaze over his face.
"What is it?" she muttered, feeling embarrassed that he continued to stare at her like that. Tanjiro reached out to caress her cheek tenderly, ears turning red. "You're so pretty" he commented, his face dusting a light reddish color.
Stomach furiously flipping, she leaned in, pressing her plump lips onto his, sweetly parted as he kissed her back achingly slowly. Rough fingers pressed into her cheeks, he brushed her lips against hers, before sweeping his tongue across her lips hot and slow, igniting their entire bodies.
She moaned softly in his mouth when his tongue delved into her mouth feverishly, curling against hers. Breathing hard, he pulled back, kissing along her jaw as he palmed her ass, squeezing it lightly.
"Tanjiro-kun", she whimpered as he began to unbutton her uniform shirt. Out came her perfect breasts spilling out, and Tanjiro was quick to fondle them in his warm hands.
Swallowing hard, Shinobu rocked her hips against the hard line of his cock straining the fabric of his trousers, core throbbing as he kissed her again, sucking her tongue into his slick mouth.
Pulling out of her mouth with a pant, Tanjiro kissed his way down her neck, over her collarbone until his mouth found her pert nipple, grounding his hips up at her in a frenzy.
He closed his mouth against her breast, all teeth and tongue, before he groaned at the back of his throat as he could fit her entire breast in his mouth, thoroughly enjoying it while kneading her other neglected breast in his hand.
After releasing it from his mouth he swiftly planted hot kisses along her breast before latching his lips back on her pink bud, his tongue laving circles around her nipple as he continued to suck and graze his teeth along her sensitive skin.
His hands hastily unbuckled her pants, and Shinobu quickly tossed them across the room until she was completely naked. She blushed as his rough hands caressed against her inner thighs, already finding slick dripping onto his fingers.
"I want you to sit on my face" Tanjiro whispered, retrieving his fingers from between her thighs and licking them clean.
"Wh—What", she said weakly, startled and dazed, he had never asked her anything like that before.
"Please", he pleaded into her ear before nibbling on her soft skin.
Shifting his way, her quivering thighs straddled him as she crawled on top of his face and found herself moaning the minute his hot breath brushed at her entrance.. Tanjiro ran his hand up her legs, pushing her thighs further apart before he dragged his tongue across her cunt, groaning heavily against her plush folds as he tasted her.
She gave a breathy moan, soft fingers tangling in his hair, tugging at it harshly as he worked her with his tongue, shoving it deep inside of her with a caressing swirl.
"Oh god, r-right there, Tanjiro-kun…", she mewled, grinding against his prodding tongue as he lapped up every bit of her essence from her core, sucking her swollen clit gently between his teeth.
Red eyes cracking open, he enjoyed the delicious sight of Shinobu's writhing body above him. Heat pooled in his stomach as he curled his tongue around her clit, her breathy and high-pitched moans shuddering through him.
Cock aching in his pants, he moved his hand down to his shorts, slowly rubbing back and forth over his crotch to the sound of Shinobu's voice in order to rid himself of some tension.
The fingers in his hair tightened as he licked her in a repetitive, careful pattern until she shattered with a scream, entire body shaking and quivering as she flooded him with her essence.
Tanjiro stroked her cunt until his fingers were slick with her wetness and he looked up at Shinobu, smirking as he slid his fingers in his mouth, licking up every drop.
Her bright purple eyes widened, clouded with lust as she looked down at him.
"You're just so beautiful, Shinobu-san." Tanjiro gazed at her in awe, removing wisps of her hair away from her face. "I can't get enough."
Shinobu kissed his palm and then kissed down the rest of his hand, leaning down to kiss him roughly on the lips, delving her tongue into his mouth. Breathing hard, he watched her as she shifted so that she was seated between his legs. She unzipped his pants, reaching out to take his cock in her warm hands, licking her lips before sticking her tongue out, taking a short lick up his head and flicking her tongue against the tip.
Tanjiro's eyes fluttered close and he let out a low moan when she pressed hot, searing kisses along his length, trailing closer and closer to the tip before dragging the flat of her tongue along the top of his cock, slowly licking up towards the head.
"Ah~", he groaned, trying to bite back his moans when she took him deeper in her mouth, taking deep heavy breaths to fight back the delicious feeling of his cock enveloped in her slick warmth.
"You're doing so good…", he rasped as her warm tongue swiped against his cock as she kept on sucking and bobbing.
Shinobu slid her mouth off of his cock, eagerly stroking him with her hand as she smeared her saliva around his length before licking a bead of his pre-cum from his tip.
Without breaking eye-contact, she slowly encased him in her slick mouth again, his fist around her hair guiding her as she bobbed up and down on his length, taking him in a steady rhythm that had his eyes rolling at the back in his head as his hips fucked into her mouth.
He pulled her off of his cock, breathing sharply as he positioned her on top of him.
Tanjiro crashed her lips fully onto hers, tasting himself in her mouth as their tongues feverishly stroked one another. He groaned in her mouth when she reached between them to run her seam along his length, soaking him with her slick before finally sinking onto him.
A muffled groan escaped his lips as her walls deliciously stretched around him in a tight heat that had his eyes rolling back.
"You're so tight", he rasped, lightly biting her ear as she grounded herself against him with more urgency, moving up and down on his cock. He grabbed her hips, thrusting upwards into her hard and fast, her soft, enticing moans pushing him to the edge. He kissed her again, swallowing her whimpers that were his name and groaned against her lips when her cunt tightened around him.
Reaching down between her legs, he played with her clit until she came apart with a choked cry; the feeling of her walls fluttering and contracting around his cock sending him over the edge right behind her. He flopped back down onto the sofa, breathing heavily as she slumped down against him, exhausted but wonderfully sated. He wrapped his arm around her, pressing his lips to her neck in a series of chaste pecks.
"That was intense." Shinobu came down from her high, panting. "I think I'm going to need another nap."
Tanjiro stroked her hair, "And I'll be right here to wake you up."
