Sitting down for dinner with his family had been a surreal experience.  Ivi easily pretended he didn't exist despite the nervous glances he shot in her direction.  His face burned with a mixture of embarrassment and the furious scrubbing he'd done to try and dry his whiskers after hurriedly washing away the evidence of what he'd done.

After, he managed to finish his homework, but now he had nothing to distract him from his own thoughts.  His phone buzzed with an alert.  A text message from Ivi read: "come to my room."  Excitement manifested itself in multiple ways.  Heat radiated from his chest into his cheeks and belly.

As quietly as he could, Zen slowly cracked open the door to his room and peered out into the dark hallway.  A thin strip of light poured out from beneath the door to his sister's room.  The house was silent.

Careful to close the door without sound, Zen scurried to Ivi's room and hesitated.  Should he knock?  Ivi didn't when she came to his room, and she had messaged him.  The thought of making any more noise than absolutely necessary left him stiff with anxiety, but he couldn't stand in the hallway all night either.  He knocked so quietly he doubted Ivi could have heard it.  She didn't call out to him, probably another good thing, and he eased the door open.

Ivi lay on her back in bed with her cellphone held up in front of her face.  She casually let her head loll to the side, directing a mischievous grin towards Zen that set his whole body shivering.  He nearly closed the door on his tail.

"Good, you come when called."  Ivi returned her attention to the phone.  "I want you to take your clothes off any time you're in my room.  Or when I come to yours.  Got it?"

Zen's tail twitched and he shifted awkwardly.  "L-Like right now?"

Ivi sighed, her voice patient with a hint of condescension.  She didn't bother looking away from her phone.  "Yes, like right now."  Ivi still wore her school uniform, gray blouse and a black skirt.  With her knees bent, the skirt pooled around her hips, leaving her willowy gray thighs exposed.

"O-Okay."  Zen only hesitated another moment before pulling the shirt over his head.  His shorts followed soon thereafter, leaving him standing awkwardly at the center of Ivi's room, fully naked.

She ignored him for another moment, thumbs dancing across the screen of her phone to finish a message before she glanced back over.  Her dark eyes immediately caught on his obvious erection, glossy pink standing out against his brownish gray fur.  His tail coiled shyly around his ankle.

All she had to do was raise an eyebrow at him and spread her legs.  The hem of her skirt settled against her pelvis, barely covering more than a belt would.  Her expectations were clear, even as his thoughts slowed to a crawl.

Zen stumbled, nearly falling flat on his face, his feet moving without input from his brain.  He squeaked in embarrassment, glancing at Ivi in hopes of not finding disappointment.  Her eyes didn't so much as twitch from the glowing screen before her, once again typing furiously.

Zen crawled onto her bed, the first time he'd ever been invited onto a girl's bed.  Ivi's long slender feet rest sole down atop the sheets, her knees bent.  She wore nothing beneath her skirt, presenting Zen an unobstructed view of her pussy for the first time.

She was stunning.  Her lithe body extended before him, short gray fur framing the thin pink slit between her thighs.  A faint glimmer of wetness caught the light, beckoning Zen.  His small erection twitched.  She offered once.  Did she want him to have sex with her?  Would she let him?  He knew the answer.  He could, but wouldn't.  His tiny balls ached with want.

Zen crawled forwards and sank his snout into Ivi's waiting cunt.  Her body tensed around him, a low hiss of breath warning that he better not stop until she told him to.  Zen lightly kissed her slit, inhaling her warm feminine scent and letting her excitement wet his own lips.

Her body was unimaginably soft, silky and springy and so overwhelmingly hot in every sense of the word.  His paws curled around her thighs to hold himself close to her body.  He nuzzled between the wonderful junction of her thighs until slick fluids coated his snout.

One of her feet lifted to rest atop his shoulder.  She let it extend down his back before raking her claws up his spine.  Zen whimpered into her pussy.

"If you accidentally cum on my bed, I'll have you lick it up, and then you can explain to Mom why you're washing my sheets at night." Ivi purred, her claws biting into his shoulder blade.

The thought hadn't crossed his mind, but her words ignited a persistent worry at just how much he was enjoying himself.  His small cock wavered, pleasure tightening his belly with a familiar desire.

He tried to focus on his task, licking at Ivi's tight lips, parting her, teasing at the tight ring of resistance that would allow him deeper if he insisted.  He tried to memorize the soft sounds she made, deciphering exactly where needed to lick and suckle and nip to get the best reaction.  The tiny secluded bead at the very apex of lips called to him, but he already knew she enjoyed that.  He wanted to understand every inch of her.

The quiet electronic camera sound rang out above Zen's head, and he jerked up, or tried to.  The foot on his shoulder kept him prostrated, but he peered up at Ivi.

"I didn't say you could stop."

Zen vacillated.  His ears burned.  "D-Did you take a picture of me?"

Ivi reached down and silenced him by grabbing the back of his head and forcing his snout back between her thighs.  "Of course I did.  Limra should know what a good little rat you are, don't you think?"

Zen tried to protest, but Ivi was ready for him this time, her fingers tangled in a cruel hold on his fur, twisting until he submit and continued to suckle her lips and let the tip of his snout massage the side of her hooded clit.

"Doesn't that sound fun?  Maybe she'll even take a turn with you too if I tell her how obedient you are.  And after spending every evening pleasing me, maybe you won't be half bad at it."  Pleasure left her words thick and saccharine, a paw lightly cupping the back of his head, her hips rocking against his steadfast tongue.

Embarrassment drove into his heart.  He wanted Limra to like him, wanted her to see him as a friend, not Ivi's perverted toy.  What would she think of him if she knew he and his sister did anything like this?  If he knew how much he liked his sister ordering him around.  Would she do the same thing?  Part of him reveled at the thought, a single tiny bead of precum dripping from his straining cock.

Zen squealed when Ivi's tail brushed the inside of his thigh.  Pleasure rang out perilously in the contraction of muscles between his hips.  He gasped into her wet lips, panting in her scent and trying to steady himself.  Her thighs tightened around his head, and he finally let himself focus on the hood of her clit, dragging slow licks up its length that set her thighs vibrating around his skull.

The tip of her tail circled his sack, lightly jostling and prodding.  They weren't heavy enough to swing on their own, drawn up close against his body, but she nudged them gently to wiggle them herself.

He whined, only just managing to stop himself from spilling his excitement across her sheets.  "Ivi please, I'll-"  Her tail brushed the underside of his shaft, and her claws reminded him to keep licking.

"You better not," but her voice lacked the same punch as it had a moment before, distant and uncaring.  Her tail curled to give his balls a light tug just shy of discomfort, anxiety and relief swirling into utter bliss.

Zen clung to his sister's thighs and swirled his tongue around her clit.  It wouldn't be enough.  Her tail curled up over his backside, and the tip prod around the base of his own until it found the small pucker beneath.  She only teased the bare sensitive entrance, the point of her tail wriggling without making any true effort to penetrate him, but it was enough.

At the same time, her own thighs clamped his muzzle in place.  Ivi moaned a quiet feminine noise that sang to something primal within Zen.  He couldn't.  Her body shook as his tongue nudged her into the powerful clutches of sexual release, and she dragged him down with her.

With Ivi's tail prodding against his hole, and hee pussy contracting against his lips in lewd approximation of a kiss, Zen barely managed to reach between his legs with one paw before he came.  Pleasure wracked his body, bundling up all the shame and confusion and desire and replacing it with animal gratification.

Warmth leapt across his palm, thin little jets of cum glazing his hand, his own touch trapping his slim twitching cock against his pelvis.  He was barely aware of Ivi relaxing around him, but she gently held him with his snout between her thighs, associating the orgasmic high with her personal feminine musk.

Eventually Ivi released him, and he shakily sat up on his haunches, the hand he made a mess of awkwardly held so that she might not notice.  Of course she did.

Ivi smiled beneath lidded eyes.  "Well, what are you waiting for?  Let me watch you enjoy cleaning up after yourself."

His belly grew momentarily weightless.  Somehow licking his own cum from the bottom of Ivi's paw seemed far more appealing.  He could go wash his hand easily enough, but Ivi's dark eyes let him know that wasn't an option.

Zen shyly lowered his head and began licking his own acrid cum off his paw.  It left a film of bitter slimy taste through his mouth, and he had to work to clean it from the small crevices between his paw pads and where it had soaked in between his fingers.  Ivi took another picture when he wasn't paying attention.

"Don't," he begged, cringing at the whine in his own voice.  If anyone ever saw those pictures, he'd die of embarrassment.  No girl would ever date him or even speak to him.  He could imagine the rumor spreading throughout the whole school before lunch.

Ivi's teasing voice sang.  "That one's just for me."  She placed her phone off to the side and gazed up at him from her pillow, black eyes gleaming.  "I know boys can't keep going.  How long will it take until you can cum again?"

A small thrill of pleasure drifted up from his gut alongside the nauseating dread.  Zen stared down at his paw, now mostly clean, then to his sheath, small cock safely tucked away inside and only a bead of cloudy fluid still clinging to the opening.  He brushed it with his thumb, then suckled it off his finger while he was still used to his own bitter salty taste.  He shrugged.

"I don't know if I can get pregnant from someone who just ate their own cum, but I'm not on any kind of birth control.  Not a risk I'm willing to take."  Ivi grinned up at him.  "But you look so sweet and helpless like that."  She pat her breast, and Zen thought she wanted him to lay down on top of her.

He awkwardly leaned forward, and when her smile widened in encouragement, Zen lowered his naked body atop her, careful of where his sheathe came to rest, just in case.  Ivi welcomed him into an embrace, guiding his head to her small breasts and stroking the back of his head.  She nudged her knee between his legs, letting his crotch rest against her thigh.

They both silently reveled in the fading afterglow buzz.  Zen couldn't deny how nice it felt to have Ivi hold him, her paw idly stroking the back of his head, one arm wrapped around his back.  The tip of her tail coiled tightly around his leg.

"Do you like being my toy?" she asked quietly into his ear.

A very similar question had been replaying through his mind for two whole days now.  He shivered, nuzzling himself closer into the gentle swell of her chest and clinging more tightly to her shoulders.  He nodded.

"Good," she cooed.  "It's a little pathetic how quickly you cum, but I do like knowing you enjoy it."  Her voice held no malice, a simple statement of fact.  "And you're so small, I bet you'd be easy to mistake for a girl."  Ivi tilted his chin upwards with one finger.  He couldn't meet her eyes, but she leaned in to kiss his muzzle to taste herself from his matted fur.  "Would you dress up in my clothes if I asked?"

Zen whimpered.  Her gentle kisses and soft voice masked the searing heat lurking within her request, her seductive voice setting hooks into his mind, tugging and pulling at him until he wanted to say yes to anything for her approval and attention.

"I want to hear you say it."  Ivi tenderly unhooked his claws from her shoulder and guided his hand beneath her shirt.  All she did was slip his fingers beneath her blouse, the soft fur of her belly hot against his bare paws.  "Go on."

Zen couldn't help himself.  He slowly stroked his paw along her ribs until he found the slope of her breast.  She wasn't wearing a bra.

"Yes," Zen whispered.  His slender paw circled the side of her breast before sweeping up and across it.  Her nipple caught against the pads of his palm.

"Yes what?"  Her chest vibrated when she spoke.

"You can dress me however you like."

Boobs felt better than he'd ever imagined.  It squished beneath his touch, firmer than he expected, his fingers sinking into her flesh before letting her curves spring back into perfect shape.  Her nipple had the same stiff yet pliable quality that made him want to spend the rest of the night simply brushing his thumb back and forth across it.

"Do like the taste of your own cum?  I can smell it on your breath."  Ivi curled his chin towards her with a single claw and stretched to kiss him on the lips, their breath mingling warmly in the bare space between.

Zen didn't, the memory fresh on his tongue, every time he exhaled.  But Ivi enjoyed watching him debase himself like that, enjoyed telling him to.  And Zen liked obeying her, wanted to do anything that she'd enjoy.  So did that mean he did like it by some weird, twisted logic?

Ivi giggled.  "I can feel you getting hard again."

Zen hadn't noticed until she said something.  His thin tapered cock already poked half way out of his sheath, slender length pressing firmly into her thigh.  Her tail uncoiled from around his ankle, and he kept expecting it to wriggle between their bodies.  Ivi sighed and gripped his back a little tighter.

"What else would you do for me?" she asked, eyes glittering.  "If I told you to get on your knees for me at school, would you?"  Zen stiffened, but Ivi didn't release her hold on him.

"W-We'd get caught!"  His fingers clung to the comforting swell of her breast.

"That's not an answer."  She wriggled against, then something slick and wet gently prod beneath his tail.  Zen instinctively tried to escape, but Ivi held him with one hand around the back of his head, the other holding the small of his back, her legs trapping one of his between them.  "Easy," she whispered into his ear.  "Relax."

Zen found that a particularly difficult command to obey.  He squirmed, something slimy leaving his tailhole wet.  He whined.  "What are you doing?"

"It's just my tail."  Ivi stroked the back of his head.  "Now answer my question."

The strange sensation teasing his backdoor made it hard enough to think, let alone speak, but he tried.  "I-I uh, I mean if you really-  Then I guess maybe."  He couldn't help his claws biting into Ivi's soft hide, but she didn't admonish him.  Her tail retreated, and Zen breathed a sigh of relief he hadn't realized he'd been holding.  With his senses alert, he felt her tail curl back in on herself, brushing his thigh on its way between her own legs.  A subtle ripple of pleasure swept up her belly, and Ivi let out a quiet sigh of her own.  If he hadn't been fully hard before, he certainly was now, and his cock buried itself against Ivi's thigh to betray him.

"What if I told you to do so for someone else?  Limra, perhaps?"  Ivi nipped one of his large ears to distract him when her tail returned to his butt.  Zen couldn't explain why his tail jumped aside at the invasive prodding.  His cheeks burned.

Zen tried to speak, but only a high-pitched noise came out.  The tip of Ivi's tail poked insistently against his slick hole.  It wriggled back and forth, applying steady unrelenting pressure.  Ivi whispered a shushing noise into his ear.  Zen struggled to resist.  Instinctive urged Zen to make it stop, but he hesitated, unsure of what to do, what to say.  Instead, he waited for the inevitable, his entire body trembling.

"Maybe even another boy?"

In the same moment Ivi spoke, Zen's tight pucker surrendered, unable to withstand Ivi's tail any longer.  It slowly spread his tight pucker, gently penetrating his ass.  Zen couldn't make a sound, his claws biting into Ivi's shoulder.  She hugged him tight, rubbing her cheek against his.

"There you go.  Isn't that better?  Just relax."

Zen couldn't relax, couldn't stop himself from fighting against the unsettling stretch sinking deeper into his rear.  She was inside him.  He could feel her warm hairless skin wriggling deeper, the tip of her tail exploring his virgin ass.  He buried his face in her breasts, whimpering into her shirt.  He couldn't tell her to stop.

Ivi's soothing voice whispered in Zen's ear, her breath hot against his fur.  "Keep that tail nice and high for me.  There you go.  Good girl."

For a brief moment, Ivi let him rest, her tail halting, though she didn't let his desperately clenching muscles force her out.  His body slowly acclimated.  Not enough to enjoy it, an abrasive heat simmering through his butt despite how well lubricated her tail was, but he wavered away from the edge of begging.

"Don't worry.  You'll learn to beg me for it."  Ivi let her tail ease back a breath before spreading him around the gentle taper of her smooth tail.

Zen took her shirt between his teeth.  His thighs quivered, wanting to escape the ever increasing stretch with nowhere to go.  Then the tip of Ivi's tail pressed against something inside of him that smothered everything besides pleasure.

"Was that it?"

Zen's mind didn't comprehend the words or where they came from.  He moaned loudly into Ivi's chest, the hand still under her shirt tightening around her velvety breast, a stiff nipple firm against his palm.  Ivi's dexterous tail began to writhe inside him, and every time the tip pressed down against his inner wall, something divine crushed his chest, his thin cock thrusting against fur and muscle.

"Wow.  Keep making those noises and Mom and Dad will come find you like this.  Are you going to cum for me?"

Zen's racing heartbeat pounded in his ears, shirt clenched hard in his teeth and what little control he held over his own body grinding against Ivi's thigh.  Her tail rippled up and down, driving unbearable pleasure into his body.  He couldn't think, couldn't hold back.

It didn't feel like any other orgasm he'd ever had.  Pleasure didn't crash over him in powerful waves but crushed him beneath a single endless weight of ecstasy.  Cum poured from his tip in one long continuous stream, heat pooling between his tummy and Ivi's thigh.  Every wave of her tail dragged out the ruthless pleasure, renewing his orgasm until he ran dry.

Zen quivered atop Ivi's chest, panting ragged breaths, her tail finally stilling, though it remained inside him, his stretched hole weakly twitching around her.  Ivi stroked his head.

"You're going to let me do that again, aren't you?"

There was no use in pretending.  Zen nodded, satisfied in a way he'd never before felt, even if he felt used and a bit sore, the presence of her tail growing increasingly uncomfortable.  His mind refused to think about anything right then.  All he wanted in the world was for Ivi to cradle him to sleep.  She didn't though, and Zen tasted his cum again that night, diligently cleaning the heavy mess he'd left in her fur.
