Here's just a little something I came up with and thought would be a fun little write and read... and I was right! Some kinky, aggressive sex that was spawned when a friend and I agreed that blood can be sexy. Hope you all enjoy!

Amber belongs to me.

Iris Blancca belongs to my good friend, Inkblot Fox


"Come on ladies, I wanna see some hustle!" Iris Blancca called out to her assembled class. "Those attackers aren't going to kick their own asses. Keep your kicks high, and follow through with your punches." The arctic fox paced as she watched the assembled women work through their self defense routines, following the moves exactly as Iris had taught them, or close enough anyway. There was only so much she could expect from college students and middle aged women, simply seeking a way to protect themselves from the muggers and rapists they feared wandered the streets at night. So long as they wanted to learn, tried their best, and paid their enrollment fees, Iris was more than happy to teach them.

"Alright, that's enough warming up." Iris called with a clap of her hands. "I want everyone to pair up and head to the mats. Practice attacking each other and defending yourselves. And remember: this is just practice, so try not to hurt each other too much. If you have any questions just call me over."

With some grumbling the women did as instructed. As usual, when it came to actually fighting another person, her students were filled with reluctance. It was the most difficult fear Iris had to work with: harming another person. These women wanted to protect themselves, but when it came down to it their humanity always made them hesitate. A little conditioning usually helped them overcome that little problem, though as Iris watched the women spar, she noted that not all her students had such qualms.

One of them, a new student who must have been in her mid twenties, was putting her partner through the ropes, her face lacking any emotion as she defended and countered all attacks, dropping the other woman to the mat within seconds of each attack. This one, looking to be part wolf and part lizard, or some such odd hybrid, was clearly trained to fight already, and had the strength and mentality to back up the moves. Iris was intrigued, a light smirk crossing her pierced muzzle as she watched the wolf work her magic. With each exchange she used a new tactic, sweeping legs with her reptilian tail or throwing the poor bovine she had been paired with over her shoulders with ease, despite the weight advantage the other woman had. This one was already well trained. Perhaps the Army shirt she wore wasn't just a fashion statement, for once.

The class continued on for the allotted time, Iris managing to pull her attention away from the impressive wolf-lizard long enough to help her other students perfect their techniques and correct their mistakes. Hopefully none of them would actually need these skills in a real world setting, but a better safe than sorry mentality was unfortunately needed for these things. And if nothing else, these women were getting in some good exercise, which never hurt. She clapped her red furred hands together to end the class, giving them all some last minute advice before sending them all home. All but one, anyway.

"Excuse me." Iris said, stopping the wolf hybrid before she could leave. "Mind if we chat for a bit?" She was certainly a curious mix, looking almost like a normal gray wolf, save for a few scaly replacements. Her hands up to her elbows were covered in smooth, dark gray scales. Instead of fuzzy paws, she had reptilian claws for feet, matching scales going up her shins to disappear under gray fur at her knees. And of course that tail, thinner at the base than a typical lizard's tail would be, but reaching down the floor and filled with taught muscle. It wasn't until closer inspection that Iris noted the small horns growing through the woman's hair, and her reptilian eyes. She must have has some interesting parents. Under all that scale and fur were muscles, well trained and ready to snap a man's neck if needed. An interesting woman indeed.

"You're quite skilled." Iris continued as the other students left, her blue eyes continuing to scan the woman before her. "You've had training before. Did the Army teach you to fight like that?"

"Yes ma'am." The woman replied, standing straight and tall at the very mention of the armed forces. "My drill sergeants wouldn't settle for anything less than the best, and I always rise up to the challenge."

"Good to know." Iris said, her grin widening just a bit as she beckoned the woman to follow her. "It's nice to know I have at least one student who knows what she's doing, and can handle herself in a real fight. So, what's your name?"

"Amber, ma'am." The wolf-lizard replied obediently, following the fox back towards the training mats. "I supposed I don't really need this class like the others do, but I've been put out of action, so to speak, and I don't want to lose my edge."

"Well we certainly wouldn't want that to happen." Iris agreed, sizing her student up once again. "I admit, I'd never seen the quality of fighter the armed forces puts out. Care for a more proper demonstration, just you and me?"

Amber raised an eyebrow at the offer, seemingly intrigued. "What did you have in mind? A performance, or were you thinking of sparring?"

"Hand to hand combat." Iris clarified. "Mix martial arts, no pads, we go until one of us submits, or passes out. Whichever comes first." She couldn't help but smirk, rolling her shoulders in anticipation of the upcoming fight, and victory if she had anything to say about it. "So, are you in? Or is the Army just a bunch of talk?"

A faint hint of a grin teased the corner of Amber's mouth, shifting her feet into a more combat ready stance. "My C.O. would kill me if I said no. And I have no intention of dishonoring the U.S. Army, not after so many years of service." She raised her arms defensively, the woman clearly ready, and perhaps a bit eager, for a fight. "I just hope you don't try and go easy on me."

"Wouldn't dream of it." Like a coiled spring Iris lunged, snapping her leg out in a high kick aimed squarely at Amber's head. a kick that was easily blocked with a raised forearm and a soft grunt. "Good reflexes. Now let's get down to some real business."

"Gladly." Without the slightest bit of hesitation Amber charged, leading with a right jab and following through with a hook of her left elbow. She moved with the speed and determination of a well trained soldier, following through with every strike and never letting a deflected blow slow her momentum. She kept the pressure up, not letting the fox back away or gain any distance, keeping her instructor in the defensive as much as possible.

"You're quite relentless." Iris found the time to comment, her hands raised in a perpetual guard. _"Is she just trying to wear me down already? I guess soldiers are trained for quick kills."_Iris had no intention of going down so easy, quickly breaking the endless barrage of punches and going in for a grapple. Amber braced herself against the change of tactics, tightening her muscles and refusing to back down. She was certainly strong, and had impressive skills, but Iris wasn't impressed just yet.

Gripping Amber's shoulder with her left hand, Iris pulled her right arm back, her muscles tensing up as she threw a hard punch for the pup's ribs, seeking to take some of the wind out of her fight. But as her fist connected she found the flesh beneath the loose shirt to be more yielding than expected. Amber broke off with a yelp, a hand grabbing at her ribs as she let out a sharp breath, glaring at Iris. "That was my fucking tit, you.. Fuck that hurts."

Iris paused at this news, having sworn she had aimed lower than that. She didn't have long to ponder though, as Amber immediately lunged for the fox, growling through her pain. Iris was instantly on the defensive again, the wolf lashing out with fists and claws as her temper got the better of her. Her anger, matched with her training, was proving much more challenging for Iris to counter, guarding every blow while waiting for an opening to counter. Amber had an impressive amount of stamina, seemingly determined to win this fight and prove her skills to Iris. The fox's arms were already starting to feel sore, and it quickly became apparent that just blocking and waiting for an opening would be a fruitless endeavor. What she needed was some space to properly counter these attacks. She never liked close quarters fighting anyway.

Finding a lull in the assault, Iris attempted to break away and gain some distance. Amber read the move and lunged in response, grabbing at Iris with a growl. Her claws gripped the fox's sports bra, and she pulled hard as Iris retreated. The sounds of tearing fabric filled their ears, half the garment firmly clasped in Amber's hand, the other half loosely clinging to Iris's body, her B-cup breasts exposed to the cool air of the otherwise empty gym.

"So, is that how you want to play it?" Iris asked calmly, tearing the rest of the formerly supportive bra away and tossing it to the ground. "Fine. But I won't be holding my punches any longer. I will make you bleed for this."

"Wouldn't be the first time." Amber countered just as confidently, dropping the scrap of cloth to the ground and retaking a defensive stance. "Let's see who can spill first blood."

Their eyes locked as the two women squared off, each feeling the other out, waiting for the right moment to strike, each wanting to gain the upper hand as soon as possible. The tension was palpable as these two skilled fighters circled each other, muscles flexing in anticipation, their senses heightening to the point where they could almost hear each other's heart beating. It was clear neither one of them intended to leave this gym without victory in hand.

Iris sprung first, her long legs propelling her across the mat with surprising speed. She snapped into a spin kick that Amber barely dodged under, then quickly dropped low, sweeping the wolf's legs out from under her in one swift motion. Amber rolled as soon as she hit the mats, avoiding Iris follow up drop kick by mere inches. With a growl the wolf-lizard crouched, then sprang like a coiled snake, lunging for Iris with claws and teeth bared.

"Too easy." Iris commented, sounding almost bored as she sidestepped the woman's lunge, slamming her elbow down on the back of Amber's neck as she flew past and sending her straight to the mat, taking all the fury out of her and leaving her to groan, stunned, on her stomach. "You'll need to be more inventive than that to take me down. You've got the skills, but I'm sensing a bit of an anger problem. And speaking of problems, I believe you owe me a top."

While Amber was still trying to shake the stars from her eyes, Iris stood over her, a devious smirk on her pierced muzzle as she gripped the wolf's shirt. "An eye for an eye." She mused into Amber's ear, before pulling with all her might. Amber yelped as the loose fabric suddenly got tight around her chest, seams tearing as the old Army shirt tried and failed to support her body weight. With a triumphant shout Iris pulled the scraps of cloth free, leaving her opponent just as topless as she. "That'll teach you to... oh my."

While Iris had simply intended to even the slightly embarrassing odds in this fight, her bluster was taken from her by the sight she now beheld. Amber's back was marred by many jagged and wicked looking scars, varying in size and shape, with the worst looking one directly about her reptilian tail, digging into fur and scale alike. "My god, what the hell happened to y-AAH!"

Iris was cut off when Amber's tail lashed up between her legs, slamming into her crotch with impressive force and leaving quite a sting for the sensitive flesh within. As the fox stumbled back, hands rubbing her groin in an attempt to find some relief, Amber crawled to her feet, finally finding the focus to stand. "I.E.D.'s are a real bitch." She answered the interrupted question, rolling her shoulders and returning to a combat ready stance. "And don't even think of going easy on me now."

Iris was finally able to get a good look at the woman now, and her earlier complaint made all the more sense. The wolf had an extra pair of tits below the first; small B-cups that were easily concealed in a loose shirt. A third pair of nipples were barely hidden in the gray fur below the second row of breasts, and smooth scales covered the center of her stomach, disappearing below her waistband. An interesting blend of fur and scale, but it left Iris with a few unexpected, though tasty looking targets.

"If anything, I've only got more respect for you." Iris admitted with a grin, raising her own fists as she overcame her shock. "If you can handle that, then I suppose I can really go all out." Without a second thought she lunged, jumping into the spin kick to leg sweep assault again. Amber wasn't fooled this time, ducking the kick, then quickly jumping over the leg sweep. Iris sprung to her paws as she finished her rotation, following through with a left hook to Amber's ribs. She continued with a barrage of punches to Amber's torso, forcing the wolf into the defensive for once.

Amber growled through the assault, doing her best to protect her body while taking quite a few blows to the arms and sides. She endured the pain, gritting her teeth through it all while waiting for her chance to strike. The moment Iris pulled back for a stronger punch, Amber lunged, taking a quick shot at the fox's stomach. As Iris recoiled from the blow, the wolf grabbed her shoulders and drove her knee into her stomach, further knocking the wind from her instructor. Iris could barely get her arms around her abdomen before Amber finished off with a final right hook, striking the arctic fox in the side of the head and sending her to the ground.

"Well that wasn't so tough." Amber commented, stretching her shoulders with confidence. She stepped closer to the downed fox, initially disappointed, and as such was taken completely by surprise when Iris hooked her leg around Amber's, kicking her weight out from under her and sending the wolf to the mat. With surprising swiftness Iris rolled onto her downed opponent, pining Amber on her back beneath her weight.

"This tough enough for you?" The white fox sneered, grabbing Amber's top breasts and giving them a squeeze, letting her claws dig into the flesh as she twisted her wrists and causing the wolf to howl in pain. "Beating me is one thing, but I will not tolerate underestimating me." She didn't relent, digging in to the sensitive flesh all the tighter as Amber tried to pull free. "Looks like I'll be getting first blood."

Amber grit her teeth as the pain assaulted her chest. But she didn't give in, squirming and fighting back against her instructor. Desperate the counter this assault in any way she could, Amber frantically clawed at the woman, scratching at whatever flesh she could reach. Her hands soon took hold of Iris's firm rear end, and she flexed her fingers with a howl, her claws tearing through the fox's shorts and digging into her supple flesh. It was Iris's turn to cry out in pain, a searing heat coursing through her ass as the tender flesh was torn into by those reptilian claws.

In the one moment of distracting pain, Amber managed to twist her body enough to throw off the fox. The two women remained tangled on the floor, punching and scratching at each other as their sparring turned into a feral fight for dominance. Claws dug into flesh and tore through cloth as the women wrestled, inadvertently stripping away the last of their clothes. Their fur was soon matted with sweat and blood and quite a few welts were already started to swell on their skin. Yet any pain they endured only seemed to drive the two women to fight harder, and dirtier.

Through the scuffle, Iris managed to pin Amber to the floor again, twisting the wolf's arm behind her back and pressing her four beaten breasts into the floor. "You made my ass bleed." She seethed, tearing away what was left of the wolf's shorts and panties. "Don't think I won't make you pay for that." Keeping Amber pinned with one hand, she raised her other high then brought it down hard, slapping her palm against the wolf's bare ass. Amber sucked in her breath as she felt the sting spread through her rear end, which only intensified when that hand came down again, with even greater force.

"Naughty... girls... need... to be... punished." Iris declared with a devious grin, smacking Amber's ass after each word. "Your ass will be redder than mine when I'm done with you." She gave that ass another hard smack, curling her fingers on impact to give it a tight squeeze. When she did, her fingertips dig into smooth and slippery flesh, Amber letting out a yelp that had the slightest hint of pleasure mixed in with the pain.

"Oh, what have we here?" Iris teased, forcing more weight onto Amber to keep her down while her fingers probed up between the wolf-lizard's thighs, tugging at the fleshy labia she found within . "It's pretty wet down here. Is someone enjoying her punishment?"

"It's just sweat." Amber insisted through gritted teeth, trying to get her free arm underneath her, desperately seeking freedom, and retribution. "Like this kind of shit would turn me on."

"Lying to me will only make it worse." Iris smacked her prisoner under her tail once more, reaffirming the threat. With a grin she leaned over, nipping at Amber's ear with a dominant gleam in her eye. "Maybe I'll let you go if you beg for mercy."

Amber's response was to twist her free arm back, elbowing Iris in the face with as much force as she could muster. Iris yelped as the elbow hit her square in the eye, and as she fell away, the wolf quickly took advantage of her regained freedom, rolling over to pin the fox on her back. She quickly hooked her knees around Iris's shoulders, putting just enough weight on the woman's chest to keep her from getting free.

"Now this is more like it." Amber growled, her long tongue snaking out of her mouth and curling around her muzzle as a hungry look flashed in her eyes. "You look pretty good down there, ma'am. And since you're so worried about the sweat on my vag, how about you put that tongue of yours to some use and clean it up. Your lessons did get me all hot and sweaty after all." She grinned menacingly, grabbing Iris's head and forcing her nose into her musky lower lips. "Now, get to cleaning. And if you do a good enough job, maybe I'll let you go."

Iris tried to argue, but found it difficult to speak around a face full of sweaty cooch. She glared at Amber, though it wasn't as intimidating with her right eyes already starting to swell shut and dried blood caking her muzzle. She was determined to not lose to this pup, especially like this, so while her nose was filled with the woman's musk, the fox managed to kick her feet up. She tightened her abdominal muscles and threw her rear high in the air, managing to wrap her legs around Amber's neck from behind. With a growl she tightened her legs, restricting the air flow just enough to slow her down.

"Trouble breathing?" Iris taunted as soon as Amber loosened her grip, instead grabbing at those powerful thigh in an attempt to get some air. "Just because you're on top, doesn't mean you are the top."

She kept her legs tight, Amber unable to loosen herself from that grip as Iris pulled her legs back, forcing the wolf to lean back and off Iris's chest, at least enough to get that sweaty pussy a few inches back from her nose. The fox was certain this would end it, willing to keep the hold until Amber passed out, when she felt a strange warmth splash over her neck. She glanced down curiously, just in time to catch a spray of hot piss straight in the mouth. She sputtered through the unwanted golden shower, Amber unable to hold it back as she fought for air. It was just the distraction she needed to finally pry those legs from her neck, gasping for air as she rolled forward off the woman, leaving a trail of piss across Iris's face as she tried to get some space between them.

"You fuckin' pissed on me!" Iris spat, golden rivulets dripping from her fur as she sat up. "You fuckin' bitch."

"Couldn't help it." Amber gasped, still trying to regain her breath now that she had regain control of her bladder. "I'd been holding it for a while. Such a waste, too."

"No one pisses on me!" Iris suddenly lunged with a growl, pouncing on Amber with a raging fire in her eyes. Amber was forced onto her back, just managing to grab the fox's wrists before she clawed her eyes out, or worse.

"I just did!" Amber snarled right back, not seeming the least bit intimidated. "And I'll do it again, too. I'll kick your ass and use you as my toilet!" Despite the raging threats, there was a hint of a smile on Amber's face, and excitement in her eyes. She was actually enjoying this brawl, all the more so with such a challenging adversary.

"Like hell you will." Iris growled right back, determined not to be bested by this woman. "I will make you submit to me, and have you licking my paws clean. By the time I'm done with you, I'll be using your tongue to wipe my ass! I'll YA!"

Iris winced as a loud smack filled the room, her threats cut short as Amber's scaly tail cracked hard against her ass, already sensitive from the claws marks that still marked her flesh. Another loud crack filled their ears as that tail whipped by again, and then again, leaving Iris to yelp and gasp in pain, and just a hint of pleasure.

"You'll be the one submitting." Amber declared with a lewd grin, not missing those subtle moans mixed in with the yelps and cries. "Call it cheating, but I have the advantage, and I refuse to lose. I'm also very... inventive."

Iris yelped again as the pointed tip of Amber's tail slapped against her pussy, then slowly slid through her lips. She shivered from the touch, but managed to glare down at the wolf all the same, struggling to fight back. Amber didn't give her a chance though, easily sliding her tail up between those lips and deep into the velvety recesses of Iris's cunt. Iris tried to keep her intimidating demeanor, but as that tail wriggled and teased at her inner folds, a heavy blush spread across her muzzle, and she was soon panting, her strength to fight beginning to fade.

Amber was quick to press the advantage. Rolling her body forward, she threw Iris onto her back, kneeling above the woman with a triumphant grin as she increased the assault on the fox's pussy. "Looks like you're all bark and no bite." She teased, ignoring her own swollen, bleeding breasts and bloody lip. Her tail swirled and thrust into Iris's cunt, frothing up her juices as she stretched the folds out tight and teased every nerve she could reach. "Bet you've never been fucked this good before. I'll have you eating me out in no time. Just give up now."

"Never!" Iris growled, regaining her wits enough to sit up, wrapping an arm tight around Amber's waist. "I'll make you cum before me, then put that bitch tongue of yours to better use!" Without warning she forced to fingers deep into Amber's slit, curling the digits deep to directly assault her g-spot, while her thumb started swirling around her exposed button. A finger from her other hand delved into Amber's ass, leaving the wolf-lizard to yelp and whine as her body was assaulted with pleasure.

Amber had to grab Iris's shoulders just to stay up, but she growled through the assault, picking up the attack with her tail. "I won't cum first." She growled, though her eyes were already starting to roll up in her head. The fox was as skilled with those fingers as she was with combat, Amber's muscles already flexing with the deep throes of pleasure. She was fast approaching climax, already turned on just from the fight, but she refused to go over the edge first. "I won't lose!"

"Just... give in!" Iris snarled, pushing off her own climax with all her strength. That tail was certainly better than any dick she'd ever had, twisting in there deeper than fingers could reach, and filling her up so completely. Her eyes were shut tight as she grit her teeth, teetering on the edge but refusing to go over. She increased her assault on Amber's ass and pussy instead, determined to not give in. "You won't beat... me!"

Neither were able to speak anymore, their attacks too severe, and the pleasure to high. The gym was filled with pleasured moans, as the smell of sex mixed with the strong scent of their sweat and blood. Their bodies tightened as the growling hit a crescendo, turning into a duet of howling as the women hit their peaks. Their bodies shivered in the throes of an intense orgasm, cumming at nearly the same time. Amber finally collapsed, panting heavily as she fell atop Iris, who was barely aware enough to catch her. The two women lay on the gym mats, panting heavily as their bodies twitched in the bliss of afterglow, sore but very much satisfied.

"I... win." Amber breathed, barely aware of her bladder emptying the last of its contents on Iris's waist and thigh. "You came... first."

"Did not." Iris managed to counter, her body still convulsing a bit. "You came just before me... I felt it. I won."

"Bitch." Amber smirked, giving one of the fox's nipples a pinch as she rolled off the woman. "How about we call it a draw?"

"Sounds fair." Iris conceded, giving Amber's breasts a light punch in response. "But I want a rematch."

"Anytime." The wolf laughed through the pain, finally relaxing next to her partner. "Oh god, I'm gonna be so sore tomorrow. You made my tits bleed."

"You made my ass bleed." Iris winked at her, smirking a bit. With a groan she rose to her paws, surveying the damage to her gym. "This is gonna take forever to clean up. Fuck it, I'll do it tomorrow." She held a hand out to Amber, smiling down at the wolf-hybrid. "I think you pass, by the way. But don't think this get's you out of my classes. I want to see you here every week, got it?"

"Wouldn't miss it." Amber grinned, taking that hand and standing up beside the fox. "Especially if it means more of these private sparring matches."

"You can count on it." That fire was still in Iris's eyes, matched by the flame in Amber's. They were going to need to store spare clothes here if this was to become a regular thing. Something to worry about later. "Come on. Let's get showered up and get outta here. Smells like sweat and piss."

They shared a laugh as they limped to the showers, arms wrapped around each other for support as much as comradery. Both had to agree: nothing can bring two people this close together quite like a good ass kicking.
