Tiffany-Twisted

"Anything you say, sis. Anything you want from me, just say the word and I'll do it."

SilverRat sat on the edge of his sister's bed, his little nose twitching, staring open-mawed at the image of his sister swaying her hips. She was slender, like most mice, her fur in almost an identical pattern to her brother, white fur with a large black patch on the right shoulder, breast and side of the face. They were twins, born only a few minutes apart; and the only major difference between them, besides Tiffany being female, was the shocking bright red hair which she wore these days. Tiffany was well aware that her brother was watching, the little mouse-boy's brain no doubt chock-full of deliciously lewd thoughts. Still she paid him no heed while she searched through her closet. Meanwhile he stared, making no effort to conceal the erection which had sprung in the cerise pink panties he wore. These were new. Or at least, Silver had never seen them before. They were certainly a comfortable pair, all pretty and feminine, finished off on the side with a little pink bow. And although they had been in the laundry basket since yesterday, they still bore the faintest trace of his sister's musk. He wore nothing else besides. His sister, by contrast, was stark naked, her whole body on display just for her brother. She rummaged through her closet with her back to Silver. And when she turned around, Silver could only stare and squirm while that underwear struggled to contain his mousey hardness. In one paw she held a pair of handcuffs and a bottle of lube, and in her other paw she held a thick double-ended toy whose longer end was shaped like an erect canine cock. Tiffany did not speak when she reached Silver, instead only smirking and raising one hind paw onto the bed, giving her brother a full frontal view of her spread sex. She dropped the cuffs onto the bed, lubed up both ends of the toy, and slipped its short end into herself with a gentle purr. Silver smiled back and stroked himself through the underwear. This was going to be fun! But that smile soon vanished when Tiffany pulled Silver's paw away from his crotch and wrapped her own paw around her brother's hardness, squeezing and stroking and using her claws, making the little mouse gasp. Poor Silver, just like every other male mouse: a hormone-fuelled fluffball. She took his side, flipping him onto his front. He landed with a yelp in his sister's thick sheets, then yelped again as Tiffany dragged him backwards by the tail. That dildo bumped against his rear, halting his slide, and Tiffany quickly gathered his forepaws behind his back. Then came the ratcheting click of metal as she secured Silver's wrists in the handcuffs. Nimble claws slipped into his underwear, right under his tail, pulling them down just enough to expose his trim-furred rear. Silver closed his eyes and tried not to squeak - he had already surrendered enough to his sister, and he hardly needed to emphasise the fact with that weakest of rodent cries. He knew what was coming, but all the same he couldn't help but squeal when the solid thrust came. The slick shaft stabbed at his stubbornly tight tailhole, time and again, the male's moans rolling and undulating in time to his sister's hip thrusts. She spared Silver no mercy; and through his breathless gasps, Silver found himself whispering to his sister, summoning the courage to reveal to her that most natural and unnatural of desires.

"Take me, Tiffany."

"Silver! What the hell do you think you're doing?"

Silver squealed and jumped at the female voice in the doorway. Silver would recognize that voice anywhere. In an instant he turned his gaze to the doorway, and there she stood: a female mouse, her long mouse-tail swishing in agitation at the sight of her brother. What a state he looked: immersed in some kind of sexual fantasy, pawing like a teenager with his dad's dirty magazines... and holding a pair of her frilly pink knickers to his nose. Panicked, Silver dropped the panties to the floor, but he kept clutching his length even as it dripped precum onto his sister's carpet. Silver felt his cheeks flush hot, glowing crimson under both black fur and white fur under the female's stern gaze.

"Let me guess what you're going to say. 'You didn't expect me home so early.' Well guess what brother, I am home early. And even when I'm not here, that's hardly an excuse to come into my room, let alone to paw through my dirty laundry like a perverted little rat. So if that's not your excuse, you'd better have a damn good one. Honestly I had no idea you were this messed up, even for the runt of the litter."

He couldn't have just gathered his sister's laundry and carried on with his chores, could he? If he was just having a sniff through the laundry, he could explain that away. Even if he ended up hard, he could explain that as 'guys and their urges'. But how do you explain yourself when you're caught, quite literally, with your pants down?

"I... I... I'm sorry sis." With his paws shaking, his voice stuttering and his ears dropped, Silver gathered up his laundry basket and trotted towards the exit, avoiding Tiffany's stare at all costs. "Here, let me get the laundry, and I'll be on my way..."

But Tiffany blocked his path with her arm, resting her claws on the wall. Silver's little heart beat even quicker, and his muzzle was all a-twitch. And as his sister lifted her head, Silver couldn't help but squeak at Tiffany's narrow-eyed grin, her two sharp front incisors on full display. Out came her paw, dragging down Silver's bare chest fur, and in an instant the male was squirming, melting into those scritches. She plucked the basket from Silver's paws, dropped it to the ground, and then she made her move, pressing herself up against Silver's front. She curled her long and prehensile tail around Silver's own, tying together with her brother. Silver sunk into her supple breasts, and his mousehood brushed against Tiffany's inner thigh, smearing her trouser leg with a trail of precum. Oh why would his erection not go away? This was his sister, for goodness' sake. Silver squirmed once again, trembling, staring past Tiffany's shoulder. What was his sister playing at?

"Aw, little brother, you're so cute when you're this shy. But you don't have to be shy around me, remember? I know what's really happening here. You got curious. That's why you snuck in here on laundry day, when I wasn't around, and started playing with my clothes. But you do like the look of them, don't you?" Silver was lost for words. He wished that his sister would stop talking, but couldn't bring himself to interrupt her. "It's such fun living with you, brother. And I would love to know how you think they feel. That's what you were thinking, wasn't it Silver? How you would feel wearing them. How you would look. Wouldn't surprise me if you were wearing this very pair in your fantasy."

"I... I... it's not a fantasy, Tiffany. I don't... want to wear women's clothes."

"Yes you do, Silver. You love how comfortable they feel, and how relaxed and free you feel when you wear them. You want to cum inside them, make a big mousy mess, make them all sticky and slippery. But more than that, you love what they symbolize. You're not like all those rough predatory males - you're much mellower than that. So here is what's going to happen. You're going to carry on doing exactly what you were doing before. Paw away. Enjoy that deep musk. Only this time, don't hide anything from me."

Silver shrugged it off and tried to reach for the basket, but Tiffany stood square in the way. "Come on Tiffany, this is silly."

"Oh, I beg to differ. This erection of yours looks serious enough."

She groped it and Silver squeaked in shock, trying to bat her paw away. But Tiffany kept a firm grip, twisting her paw around her brother's hardness, before dragging her rough paw pads down the mouse-boy's length, drawing quick stuttering gasps from the snared rodent. She moved onto his famously weighty murine balls, twisting them in her paw and even digging her nails a little into his furry sac.

"Sis please, don't do this."

Tiffany groped her brother again and whispered right by his ear. "Why not, little brother?"

"Because this... this isn't something we should be doing. Your paws on me... this is wrong."

"Oh sorry little brother, you're going to have to think of a better excuse than that. It's just you and me here. Who here is going to tell us this is wrong? Who even has to know? Besides, if you think it's so wrong, then how do we explain this rather big erection of yours which I'm holding in my paw?" Silver hesitated just for a second, but that was enough. "Exactly, brother."

Tiffany released her brother. He swallowed hard, and ducked down to scoop up the panties. Rising to full height, he stared at his sister with black pearly eyes - he was still pleading, bless him, even while his mouse pre dripped to the carpet. Tiffany gave a quick downward glance at Silver's arousal, a smirk, then a stare back into his eyes, and the mouse-boy practically whimpered, whimpered under his sister's judging glance. Clutching the panties in one shaking paw, he brought them up to his whiskered snout and inhaled. Their sweet mousy musk sent a shiver straight up Silver's spine, and he twitched his nose, taking another deep sniff and indulging himself on that scent. He closed his eyes and murred a happy trill, sliding a shaking paw down his side and gripping at the heavy erection which sat above the waistline of his pants. By now, Silver could hardly care less that his sister was standing just inches away. He took another deep sniff of his sister's panties and curled his claws tighter still around his length, his whole body twitching, precum dribbling all over his claws. With quick little gasps and a flick of the hind paw, Silver stroked himself nice and fast with a toothy smile, losing himself in his thoughts, only stopping when Tiffany laid her paw across his.

That's a good boy. Now, put them on."

"Well... I don't want..."

"Silver. Put on the panties."

Silver sighed. However, he tugged and stripped away his clothes without any further questions, pulling his shirt over his pointed ears, and slipping his pants the rest of the way down his legs. Finally he slid his boxers down and tossed them away, leaving his fuzzy body completely exposed. He picked the panties off the floor and bounced over to his sister's bed. He balanced on the mattress while he slid in one clawed paw, hopping onto that foot and sliding the other in, smiling to himself as his trim fur brushed against the lacy fabric. He struck a little pose for his sister and she nodded in approval. In fact, from what Silver could tell, she almost broke into a smile.

"There we go. Now, that suits you much better. A girly little mouse like you, in pink panties. What could be more submissive and sissy than that?"

Silver's ears folded over, and his voice dropped to a bare whisper. "I... I'm not a sissy..."

But Tiffany prowled over to Silver and put a claw to Silver's mouth, shushing him. "Yes you are, brother. I saw that smile. This is who you are. But you know I won't judge you for who you are. We are family, and I will love you regardless."

He glanced sideways, catching his reflection in his sister's full length mirror. A slim mouse stared back at him, its black-and-white fur on full display and its long naked tail resting on the ground. Silver grinned and raised his head, his gaze lingering on the arousal which was once again hardening in the confines of those pink silken panties. How could that little mouse in the mirror hope to compete with every muscle-bound wolf and stud lion out there? Still, Tiffany was right: the two siblings had each other. And if she was happy, he was happy as well. Silver's cheeks flushed red. "I love you too, Tiffany."

Tiffany had been planning a quiet evening. However with her brother's help, she could still unwind. With Silver watching on, she unbuttoned her work shirt, slipped it over her shoulders and cast it aside into Silver's laundry basket. Next came her trousers, and Silver couldn't help but chirr at the sight: underneath her work pants, Tiffany was completely bottomless. She stood wide, her footpaws splayed on the carpet for balance while she brought her paw between the bra cups, reaching for their front clasp. She snapped it open, and dropped this final piece of clothing to the floor. She smiled at Silver, a proud whiskered smile, and Silver breathed in deep as he caught a fresh scent: the scent of his sister after a hard day's labour. He had seen plenty of his sister's bare fur on lazy weekends, when neither sibling chose to wear much more than underwear. Of course he stared, the little hornball. Any mouse who liked girls would stare when they saw a slender and curved female stroll by in little more than a bra and knickers. Tiffany had never discouraged him from staring though. Boys: always more fun when they're younger than you.

"Well here I am, then, brother. This is what you wanted to see, wasn't it? Your sister, an athletic female rodent, naked as the day we were both born. But just a little bit more 'developed', of course, if you understand me."

As if on cue, a bead of her nectar trickled down her leg. SilverRat couldn't help but squeal at the sight. Tiffany's sex was coated with glistening moisture. Claws crept closer to those folds, and she dug in her clawtips, just the clawtips, tweaking them and coaxing out more clear beads which ran over her furry paws. That got Silver groaning. He groaned louder when his sister planted both paws on his chest, one of them damp and musky after her masturbation, and he groaned louder still when she pushed him backwards onto the bed. Without another word she leapt on afterwards, straddling her waiting brother. With an eager little huff, she pressed her hips to his sheath, and ground her nethers against the male's straining cock, both of the twins' juices soaking the thin layer of fabric that separated them. Now he could smell them together. His sister's scent was now ten times stronger, blending with his own scent in a rich cocktail of mouse musk. He knew this was wrong. He tried to ignore the hundreds of lewd thoughts which were crossing his mind, and when that failed, he tried to picture other mice in her place: celebrities, high-school crushes... but every time, his thoughts returned to his sister. They were crossing so many barriers: cultural, familial, natural... But here, in the little house which the siblings shared, none of those barriers mattered. They had always been close, even as far as siblings go. Yet Tiffany was no longer a girl, but a smart and, dare he say, sexy young woman. Yes it was an animal need they were sating - they needed to mate, like the farmyard vermin from which they evolved. But more than that, Silver loved his sister. And Silver would indeed do anything for her.

"Isn't this just so naughty, brother? Something which no brother and sister should ever do... what would Mom and Dad think? And yet just the slightest slip, from either of us, and we'd be there. Look how close you are Silver, to slipping inside me.... to penetrating me."

Now that comment really got Silver squeaking, and he thrust up his little hips and clutched at her hips, even digging in his claws a little until Tiffany swatted them away and immediately stopped grinding, turning up her muzzle in a scowl.

"Watch what you're doing with your claws. Little sewer rat."

Silver cringed underneath his sister. Even then his mousy length twitched within the panties, and he moaned at the sudden lack of stimulation. But rather than continue, Tiffany climbed off her brother and ordered him not to touch himself, leaving his cock to strain within the tight panties. The thin fabric tented over Silver's fierce erection, doing nothing to contain the copious precum which the little mouse was leaking. Why did she have to stop now? He was so close.

"What's the matter, Silver?"

His voice was breathless, almost a whisper. "I'm sorry sis, I can't help it. I... I just like..."

"Go on?"

Silver was breathing hard. "I... I really liked that. Please do it again."

But Tiffany simply knelt beside him, watching him squirm on the bed. The cool silky lace rubbed over his length, and he jumped and squealed, filling the panties with another spurt of mouse precum. He whispered up to Tiffany. "Oh please sister, don't tease me like this. Look at the state I'm in."

"Yes Silver I see you, lying there, shamelessly erect in my pre-soaked panties. You look so cute down there. Almost as cute as when you were pawing away earlier. Do you remember what you were saying to yourself, just as I walked in?"

Silver said nothing

"Say it again."

Silver's throat was dry, and his eyesight hazy, as he croaked out the words. "Take me, Tiffany."

She sprang back on him, wrapped her tail around his legs and resumed her rapid grinds. This time however, she dipped her hips forward and nestled her folds around the tip of Silver's covered cock, before bucking her hips with a lust and a rapidity well suited to a quick-breeding rodent. He was actually slipping inside her. The panties stopped him one or two inches deep, but only that tiniest layer of fabric kept Silver from properly penetrating his sister. The look of horror on her brother's face... it was just so adorable. Still Silver did not dare to bring his paws between them. Tiffany wanted more, and she was going to take it.

"Mmm yes. Now there's a good boy. I'm nothing if not generous. Besides, there's no harm letting my brother empty his big nuts this soon. Because I know what a frisky little critter you are, and I know you'll still have another two loads in you. At least."

Indeed Silver hardly needed any more stimulation at all. He swallowed hard and broke into a rapid pant, shaking from whisker to tail. Tiffany noticed too, and she called down at the prone rodent.

"Hold yourself hun, while you cum. Keep it all in your panties. I want to see all the mess you make... see how much it makes you squirm."

Silver nodded again, perhaps a little over-eagerly, and held the base of his mousehood. Tiffany rolled her hips harder, holding Silver to the bed with a firm paw to the chest, feeling her brother twist and wriggle underneath. She wrapped her legs around him, gripping him with her knees. Suddenly, with a high-pitched squeal, SilverRat screwed his eyes shut and arched his back, hissing through his top teeth. His heavy murine sac rolled in the tight panties, the fuzzy sac bristling against his sister's silk. Then the little mouse began bucking and yipping and squeaking, crying out his sister's name as he filled the panties with warm mouse semen, that familiar male musk rising quickly between the siblings. His hardness rubbed and slipped inside the underwear, deliciously slick with that thick mousey load, and he collapsed back onto the bed, underneath his sister, all whiskers and giddy smile.

"I'm... I'm sorry sis. I just couldn't hold back." He coughed and gave a wan chuckle. "Heh. I guess I really needed that."

Tiffany just sniffed and stared down at the spent male, tossing back her hair. Suddenly Silver cried out as her manicured claws wrapped around his testes, squeezing, feeling their weight.

"My, these are still lovely and heavy. We aren't done yet, by any means. I know what you mouse boys are like when you get excited."

Tiffany climbed clean off the bed and headed for her closet. Silver craned his neck, trying to watch his sister rummage through her belongings. He was already panting, and grinning, eager to see what his sister had in store next. And when Tiffany turned towards him, clutching a smooth and purple and deliciously thick strap-on, Silver gave such a shrill squeal of delight that he actually had to stuff his paw over his muzzle. He certainly didn't want all the neighbours hearing their randy little squeaks and murrs... or his squeaks at least. Would Tiffany squeak? And just how voracious would she be? He tapped his paw on the bed and watched Tiffany stalk towards the bed, swinging the strap-on from her foreclaw. The mouse in pink felt his arousal stir once again, rubbing lewdly inside panties already saturated with mouse cum.

"Be careful what you wish for, brother."
