“Oh… Ouuhh… Miss Shinobu, I feel strange…”
Shinobu leaned forward in her chair, a bright smile on her face, and laid a hand against Tanjiro’s forehead. “The medicine must be working! Could you describe how you’re feeling?”
“I feel… short of breath. I’m hot all over and, uhm…” Tanjiro swallowed thickly, his neck muscles working beneath his skin. Shinobu was getting close now, leaning over his bed so her chest almost touched his stomach. He shivered. Normally he wouldn’t notice such things about other people’s bodies, but right now… Why was he so sensitive? He discreetly moved a hand to cover his swelling groin, hoping Shinobu wouldn’t notice—
She grasped his wrist and forced his hand away.
Tanjiro gasped and stared into Shinobu’s eyes as she leaned in to kiss him. Her warm lips rolled across his own, suckling briefly against his skin before pulling back again. The touch was electrifying, driving bolts of pleasure into Tanjiro’s body and transfixing his attention on her.
“Whh…?”
“The medicine works perfectly,” she said as her small, delicate hand fell on the big lump of his bulge and kneaded it. Tanjiro clenched his teeth and arched slightly where he lay, a moan bursting from his lips as she started to manipulate his pleasure with surgical precision. A soft, sly smile curled her lips as she groped his bulge, feeling it throb and stir beneath her palm and slender digits. “My, my,” she said. “You are a virile one, aren’t you? It’s all that training you’ve done…”
“Miss Shinobu, how is this… nngh… supposed to help recover my stamina?”
“Is that what I said?” Shinobu cocked her head to one side and hummed. “No — this will be a test of your stamina. You’ve advanced faster than most Slayers; if it wasn’t for a few individuals, you’d be a prodigy among prodigies. I want to help you with your journey…”
As she spoke, the Insect Hashira climbed onto Tanjiro’s bed and straddled his groin, her thick thighs squeezing his hips. Feeling her crotch smushing down onto his, Tanjiro groaned and grasped the bedsheets tightly, feebly resisting the overwhelming pleasure. Was this really happening…? He huffed and puffed huge breaths, his chest heaving in and out as his thoughts melted into lusty soup. Before long, his hands left the bedsheets and grabbed Shinobu’s hips instead – which made her giggle and lean down for another kiss.
This time, he kissed her back, moving his lips needily against her own while he massaged her narrow waist up and down. She shimmied her butt from side to side, and soon he was groping that too, surprised by how plump and rounded her cheeks felt under his hands. “Uhn…nngh…!” He flicked out his tongue to meet hers, and grunted in shock when she bit its tip gently, glowering deep into his wide, nervous eyes.
Shinobu grasped his wrist and led it down… down, between her thighs and under her robe. There, he was shocked to feel the bareness of her wet pussy pressing against his fingers. Dragging a shaky breath, Tanjiro curled his digits against her sweet, tight lower lip and started to knead them gently, massaging her vulva, her clit… making her croon in bliss. She continued to guide him for a few moments, making sure he was pleasuring her right, before winking and climbing off of him again.
“Get up,” she said.
Tanjiro rose, and together the two of them undressed, unable to look away from each other’s bodies as they stripped down naked. Soon they stood bare before each other, breathing heavily, red-faced and needy. Shinobu was curvier than she looked; though short, she had a wide pair of hips and an utterly delicious ass which she rested one hand upon as she stared at Tanjiro. Tanjiro, meanwhile, was just as hung as she’d expected… because she’d already marvelled in awe of its size when treating him in the past. Of course, he’d been unconscious at the time, so he couldn’t know she’d already gotten her hands on his massive sausage in the past, and measured it against her forearm, and buried her face underneath it to sniff… Shinobu was a naughty, naughty doctor.
“Is it…big enough?” Tanjiro asked, taking Shinobu’s lack of surprise as a sign of disappointment. She smiled wide at him, and stepped forward to bump a knee against Tanjiro’s hip, lifting her foot off the ground. Her left hand went to his bare cock, grasping and groping it, stroking it back and forth. Tanjiro groaned. He was already half-erect, and Tanjiro’s touch spurred him to full arousal, throbbing and twitching hungrily in her grip.
“Good boy,” she said. “I hope you stay just as eager after I’ve milked you.”
Was she talking to him, or to his cock?
Tanjiro gasped as Shinobu pushed him down onto the bed and squatted between his thighs. She took his giant jumbo-dick in both hands and jackhammered it up and down, pumping him until he oozed precum all down his own shaft…her hands spreading it evenly across his member as a layer of slippery lube. Once he was properly glazed, and staring at her in utter desperation, Shinobu pressed the gentlest of kisses against the tip of his cock. Tanjiro yelped, his eyes blurring as his cock bucked and leapt in her grip. He was helpless before her, unable to resist even a little…and when Shinobu opened wide, Tanjiro knew he was about to lose his mind to pleasure.
Schlurrrp! Schlup, schlup, slurp, slupp! Shinobu started to noisily blow him, bouncing her face up and down his colossal dick and sending waves of ecstasy throughout his muscular body. Tanjiro wailed and moaned in total pleasure, unable to look away from the sublime beauty burying his cock deep in her mouth. Her lips glided up and down his tender dick, refusing to stop or give him a break even once. As she sucked – sslrp sslrp sslrp sslrp – she massaged his balls in one hand and teased his asshole with the other, swirling two fingers slowly around his twitching rim. When she started to poke those fingers inside him, Tanjiro arched his back and nearly went cross-eyed from the pleasure of it all, gurgling as he shot a thick rope of precum into Shinobu’s mouth! She didn’t even pause; she just swallowed and kept messily slurping his dick, even as webs of spittle started to dangle between her chin and Tanjiro’s balls! She kept her eyes on him, sucking with power and skill, practically torturing his cock with unending waves of pleasure!
Tanjiro couldn’t take this for long. He could feel his orgasm building up in the base of his cock, threatening to blank his mind and steal his thoughts. He gripped Shinobu’s hair tightly, guiding her up and down, leaning back until he was sprawling on the bed once again…and he prepared for an explosion.
“Nnngh… hnnghh… Shinobu…!”
SLLRP SLRRP SLRRP SLRRP SLRRP!
Shinobu’s only response was harder, faster, more violent sucking; she sealed her lips vacuum-tight around his cock, stretching out her mouth in an obscene suckface while her eyes gleamed with depraved want. She hoovered him without mercy, until at last, Tanjiro’s hips lifted, his hands clamped down, and he erupted down her throat with a monstrous deluge of seed! He blasted cum in white salvoes, moaning and groaning as he flooded her gulping neck full of jizz. Shinobu swallowed and swallowed, but even she couldn’t get it all down fast enough; cum burst from her nostrils, and her eyes rolled back even as tears streaked down her cheeks. Shew didn’t stop moving, though, not for one second; she kept on slam-sucking Tanjiro’s cock until he’d completely drained himself down her gullet!
Splrrrrt! Splrrrrt! Splrrrrrsh…!
At last, panting, Tanjiro let go of Shinobu’s hair. She dragged back and popped her lips off his cock, then licked his dick for the next minute or so, making sure to clean all the sticky cum off his meat before showing him her open mouth, tongue rolled out, breathing heavily.
“Haah… Haaah…”
Tanjiro shivered and hooked a thumb into her mouth, caressing her as his spent cock continued to twitch and dribble. “That was—”
But Shinobu grasped his cock and squeezed around the hilt, making him cry out. “Mmm…” she groaned, and kissed his tip hungrily. Smwack! “I’m not letting you go soft yet; not until I’m satisfied.”
Then Tanjiro noticed her other hand holding the needle. The empty needle. A tiny pink pinprick ached on his arm.
“What—” he said — but then the new ‘medicine’ set in.
-
“Augghh! Ungh, ungh, ungh, ungh!”
PLAP PLAP PLAP PLAP SLAP SLAP PLAP!
Tanjiro squatted over Shinobu, hoisting her legs up to her shoulders and ramming her soaking cunt with all the power his trained body could muster! Red-faced, his tongue hanging from his mouth and butt jiggling wildly, Tanjiro pounded Shinobu with manic force, grunting and gasping as he stretched her out like a cocksock!
Shinobu could only wail and whine as the brute fucked her without mercy, slamming every last inch of his giant dick in and out of her with each butt-rippling pump. The wobbles spread across her thighs and asscheeks again and again, playing her lower body like a drum as he rode on waves of drug-fuelled ecstasy. He needed to cum inside her; nothing else mattered! WHAP, WHAP, WHAP, CLAP, PLAP, SLAP! Tanjiro rang out loud, wet claps with his savage thrusts, jackhammering his hips way beyond the point of exhaustion, crushing Shinobu’s breasts beneath his hard chest as he squeezed her ankles above her head! He plapped Shinobu with brutal repetitions, driving toward his limit more with each passing second. Sometimes he kissed her deeply, tongues swapping spit, and at other times he rested his chin on her shoulder as he jiggled her stupid. All the while, the pressure inside him grew and grew, his balls clenching, his cock fattening, his—
SPLURRRRRRT!
When Tanjiro came, he smashed his hips down and flattened her asscheeks underneath them, pancaking her under him on the bed as he blasted her womb with giant pumps of cum. Shinobu squealed as Tanjiro filled her, bloating her belly out tight and tense while she squirmed and gurgled in fucked-dumb abandon. Her tongue hung out, her eyes rolled back, and she ahegao’d like the uber-slut she was as he moulded her ass with slow, grinding rolls of his hips.
Slrrrrp… POP! He pulled out and whapped his meat on Shinobu’s thighs, wheezing for air in the aftermath. Her cunt sprayed jizz as he sat down beside her, panting, staring up at the ceiling.
“Hnnnh… I think… my stamina might have improved,” Tanjiro said exhaustedly. “But… we ought to do this more often… if I really want to get better. Right, Shinobu?”
Shinobu’s only response was a shaky whine.
