When Kevin first moved in with Natalie and Luisia, he'd been too relieved to do much of anything other than be grateful. Not only about finding affordable rent, but sharing a home with two gorgeous sisters? Admittedly, they were a bit older than him, but that hardly bothered him. If anything, it thrilled him!

Perhaps because of this, he hadn't taken the first changes seriously.

Now though... Now the blue glow of his computer screen lit his worried face as he spooled through articles on the net.

Resurgance of Beast Virus. Who is Safe?

Mutation Prompts Quarantine Fears.

Act of God or Escaped from a Lab? Questions Need Answering.

Kevin bit his lower lip as images flashed across his eyeballs. He knew this wasn't helping things. He knew what he was supposed to do. Everyone did since the last major Beastgirl outbreak fifteen years ago. If you see the signs, you call the Quarantine Office. Beastgirlism exclusively impacted women, transforming them, rewriting their DNA with that of various animals, but it could be treated. He knew this.

And yet, as if compelled, he delved deeper into that yawning black pit of information with a flick of his finger, scrolling straight to symptoms. There was a lot of them, that was for sure, each depending on what kind of beast the woman was turning into. Scales for a serpent. Fur for a dog-girl. A sudden expansion of the chest and tendency to moo with the cow-girls.

But the one thing they all had in common was the heat.

Kevin shivered, licked his lips. This was why the women needed to be quarantined. Whether due to the fever that brought on the changes or just a nature of the transformation itself, every beastgirl infected went into a breeding heat once they'd progressed far enough. And though beastgirlism didn't affect men, the pheromones the women emitted surely did. Few men could properly resist a beastgirl's influence, meaning any infected were required to quarantine until cured, lest they turn the men around them into dumb breeding studs.

Kevin shook his head as if to clear it. With grim purpose, he rose from before the screen. No more delaying. He had to call the authorities. He searched the gloom for his phone, before realizing he had likely left it in the kitchen.

Warily he peeked out of his room, scanning the dark hall. No one was about. Quiet as a thief, he slipped out of his room and padded down the hall, only to pause when he heard the tv in the living room.

"C'mon ladies, lift those legs. One two. One two. One two."

Natalie must be doing her exercises. Kevin hesitated, but avoiding her would do him no good. The kitchen was on the opposite side of the living room. He had to pass through. Men can't be infected by the virus, he reminded himself.

As if that was his real concern.

Steeling himself, trying to move as silently as possible, he stepped out into the living room. He tried not to look at the figure stretched out on the floor before the tv, lit by its phosphorescent glow.

"Mmmm... Kevin?"

Kevin stopped dead.

Natalie had cocked her head towards him, her body lit by the tv as she rolled slightly onto her side. At such an angle, it was impossible not to admire her curves. Her hips were wide but not fat, firm with the care she took in her middle age. Shapely best described her, with a mature, soft beauty wrapped in an exercise leotard that only further drew attention to her figure.

But the most striking part of her was the spots.

At first they had just been some blemishes along her arms and back. Kevin had assumed she'd had an allergic reaction to something, which was why he hadn't called the authorities before. Only when they darkened further did he begin to grow concerned. Now, they patterned down her thighs and across her back and arms, nestled among soft, gold and crimson fur. The fur of a leopard.

Natalie eyed him, and he noticed that her pupils had become slitted like a cat's. Her hair was a rich river of red that tumbled over her shoulders and fanned about her face as she tilted further to face him, her breasts wobbling in the confining, tight black fabric of her leotard.

"Ah. Hi, Natalie," he said. "Just... heading to the kitchen."

"Were you?" she said, lazily stretching, her breasts straining the shining fabric she wore. "Mmm. In that case... Would you mind grabbing me a glass of milk?"

"S-sure," Kevin said, hastening across the room and into the kitchen before she could say any more.

He flicked on the light, the harsh glow washing over the counters and linoleum flooring. His eyes darted about for his phone, but he didn't see it where he usually left it. Did one of the girls move it? He felt the beginning of panic and forced the tightness in his chest back down. No. No, it was probably just misplaced. That was all. He'd get Natalie her drink, then take a better look. The harsh light of the fridge washed over him as he opened it and rooted around for a bottle, reluctant to leave the coolness. Just looking at Natalie had made him hot and flushed.

To be fair, she'd had that effect on him even before her infection. He'd always admired the older woman. How well she kept her figure, and the certainty in which she did everything. A maturity of years and experience that made him feel oddly safe with her. Secure. Like she knew just what to do. It was so easy to go along with her. Even when she first began showing signs of beastgirlism she never panicked or acted out. She'd just gone on with her life.

But that had only been at first.

Kevin had sensed a change in the last week. Natalie had begun growing more brazen with her figure. She had never been ashamed of her body, but of late she had begun to fairly flaunt it. Wandering the house in nothing but her exercise clothes, which never seemed to fit her properly, stretching against her every curve, outlining her figure like the wild dream of some master sculptor. She'd begun lingering in the bathroom in nothing but a towel. Hovering around him whenever he came out of his room. Teasing him with delicate touches...

Kevin flushed harder. Stupid. Stupid! Was that why he'd waited so long? Had he finally thought he'd have a chance with the lovely milf? Fucking moron. With a sigh his questing touch finally found the cool glass bottle of the milk. He pulled back, shut the door and turned around.

And nearly rebounded off a pair of soft, pillowy tits.

Natalie stood before him, lazily wiping the sweat from her face with a small towel. Her breasts stretched the slick fabric of her leotard with her every breath, the subtle tang of her sweat mingling with a muskiness that made Kevin's head spin.

"Mmm. Thank you," she said, plucking the bottle of milk from his limp hand, her claw-tipped thumb popping the top off with a flick.

"Uh, y-yeah. Don't mention... it..."

Kevin trailed off as Natalie tilted her head back, downing the bottle with a lusty thirst. He watched her throat work, some of the cream spilling from the corner of her mouth, running along her chin and drip, drip, dripping onto the soft orbs of her breasts. She took away the bottle with a gasp, smiling down at him.

"Mmm. Just what I needed. Now... Kevin? Would you mind helping me with something else?"

He jolted back to the present, realizing he'd been breathing deep her scent. His face grew hotter than even before, and his cock had grown thick in his pants. "E-else? What um, what else?" he asked.

She lazily rolled her neck and shoulders, every movement further drawing his eyes to the way her soft breasts moved upon her chest. "Mmm. See, I've been so... stiff lately. I could really use a hand stretching."

"Oh," Kevin said, his eyes roaming to try and keep him from staring at her breasts. "I dunno..."

"Please, Kevin," she said with a woeful look. "For me? In my time of... need..."

Kevin winced. She really was having a hard time, he had to admit. And it would only be worse once he made that call and she was quarantined. It... it would only be fair to help her get a bit of... relief considering what was going to happen soon. At last, he gave a nod. "Well, okay. What ah, what did you need?"

Her smile was as coy as a cat's when cornering a mouse. "Thanks, Kevin. I knew I could count on you. This way."

She turned, the swing of her ass making Kevin swallow hard, but he nevertheless followed her back into the living room. He shot a last look into the kitchen but... but he could look for the phone later. This wouldn't take long.

Yeah, he thought, inhaling deeply as he stepped into the living room, where the spicy tang of Natalie's scent hung like a mist in the air. His body relaxed a little more. His worries easing away.

Yeah.

He could do it later.

The flicker of the television glowed against the wall like a window into an empty void. Kevin stopped near the couch, watching as Natalie slid down to her knees, stretching her upper body at an angle on the floor.

"Here," she purred, wiggling her rump. "I just can't seem to... mmm... stretch properly. I need you to get behind me and help... ease the kinks out of my back."

Kevin stared at the provocative pose; her ass outlined taut against the smooth leotard. How it didn't tear he had no idea. "I uh... see. And, how would I..."

"Just get down behind me," she said with a glance over her shoulder. "And I'll show you."

Kevin hesitated, but he had signed off on this now, so did as she bid. As he crouched behind her, he reached over her shoulders and pressed his hands against the small of her back.

"Mmmm," Natalie hummed, arcing further under him. "Little higher."

Blushing, he did as she bid, sucking in his stomach lest he touch her, his hands sliding along the smooth fabric of the leotard, then onto the soft fur of her back. He couldn't help but breathe in, inhaling a gust of her spicy scent. Kevin blinked, his head whirling and cock throbbing.

"Mmm. There we go," Natalie said. "Now, start rubbing circles there. Press forward, Kevin. I know you can do it."

"Sure," he said, obeying. His fingers pushed against the smooth fur of her back, the heels of his palms pressing down, massaging her in slow circular motions, his hands slipping higher and higher.

Kevin sucked in a breath as he felt himself lean down atop her back, his crotch pressing against the softness of her bottom, his cock rubbing against the seam of her ass. A soft purr came from deep within her, a sound that vibrated through him like a song. "Mmm," Natalie moaned. "There you go. Keep pressing, Kevin. You're doing soooo well."

"S-sure thing," Kevin said, breathing hard and fast as he did as bid, massaging her back, his cock sandwiched between him and her, rubbing with every stroke of his body. The softness of her fur brushed through his fingers. The sweet muskiness of her body tickled his nose, making his head spin.

"N-Natalie-"

"Call me Miss Kitty," she breathed.

"E-excuse me?"

"Go on," she hummed, pressing her ass further against his crotch, rocking more insistently against him. "Say it..."

Kevin wasn't sure he should. Something about it had a feeling of crossing a Rubicon. That if he did, he couldn't go back. Yet the words tingled on the tip of his tongue. The way she rocked against him sent aching pleasure throbbing through his cock and into his balls. He felt so warm. So flushed. So uncertain and aroused.

"M-miss Kitty?" he gasped.

He felt the words surge through her. A shiver of pleasure racing from her tail to her head, rippling through her with a subtle tensing of her muscles, moving beneath his stroking hands with a deepening of her purr. "Mmmm. Yes, Kevin?"

"You ah, seem really flexible. Are you sure you don't-"

"What is going on in here?"

Kevin jolted with surprise and straightened sharply, looking towards the doorway. A busty silhouette filled it, almost too tall to fit through. A perfect hourglass of narrow waist and wide top and bottom, hands on swelling hips and head lifted in judgement.

Kevin stared, jaw dropping as the figure stepped into the room, the glow of the television illuminating her more clearly. She was wearing a fuzzy pink bathrobe and nothing else. Despite the belt being cinched at the waist, it had very clearly been designed for someone several sizes smaller in the chest and body. Her neckline plunged so deep the robe was barely able to cover her nipples. In fact, Kevin could see the edges of those soft, pink areola against the fabric.

But it was the stubby cow horns that betrayed her infection.

Luisia had always been a big woman, but she had grown, that much was clear from her ill-fitting robe. The horns were new to him, though. Rising from a mane of brown hair, they curled tantalizingly above her head. Some soft tufts of fur clung to her wrists and ankles, her face striking, beautiful, with all the motherly indignation of coming across a child misbehaving.

"Luisia," Natalie hummed, cocking her head towards the cow woman. "What are you doing here?"

"Wondering what you two are up to," she said, giving Kevin a shrewd look. "Well?"

"I uh... This isn't what it looks like!" Kevin gasped.

"He was just helping me... mmm... stretch..." Natalie purred.

"Oh really?" Luisia said. "That's not what it looks like to me."

Kevin winced. "I-"

"He clearly doesn't know how to do it right. Here, let me show you."

It took Kevin's mind a minute to process what had just been said, and that moment of hesitation was all it took for Luisia to cross the room and plop down behind him. Kevin started up, but before he could go an inch Luisia had knelt behind him, the pillows of her breasts pressing him back down against Natalie's back, sandwiching him between the two sister's curves. Kevin froze, too shocked to properly respond to what was happening, gasping as he felt the burning warmth of Luisia's body against him, a heat that seemed to seep into him as she pressed against him.

"Here we go. Now, use your hands like this."

Her arms moved around him, her hands grasping his and pressing them into Natalie's upper back. The leopard-girl moaned as Kevin found his palms and fingers pressing down into the space below her shoulder blades, Natalie curling against the floor, her plump bottom grinding against his bulge insistently, his hardening cock throbbing in the prison of his pants.

"Oooooooh fuck!" Natalie moaned. "Just like thaaaaaat."

"H-holy fuck," Kevin gasped.

"See?" Luisia murmured in his ear, working his hands against the catgirl's back. "Just like that. See what you can do when girls help out?"

Kevin had no idea what was happening. His body was moving on autopilot, obeying the touch of Luisia, his breath coming in gasps as Natalie's bottom relentlessly ground against his groin. He groaned, lost in the pleasure of her body, his pulse thumping. His back mashed by Luisia's ample breasts. A scent of rich cream and heavy, pleasant perfume mingling with Natalie's feminine musk, making his head spin and throb. He was so hot. So warm. He couldn't seem to think straight. Something... something about this was wrong. But he couldn't put it into words. Couldn't focus.

He could only feel.

Feel the soft bodies moving against him.

Rubbing him.

Teasing him.

Feel his pulse thump with arousal and need.

"Good boy," Luisia murmured, her lips gently kissing his ear. Sucking on the lobe, making him jolt and whimper. "Just keep going. Keep massaging Natalie like that. Just breathe in. Out. In. Out. Nice and slow. Nice and heavy."

"L-Luisia! I... ah... I..."

"Are you uncomfortable? Mmm. No wonder," she murmured, her hand leaving his and moving between him and Natalie, her finger sliding against the tenting bulge of his cock, rubbing his tip through the fabric even as his cock was squeezed between the soft globes of Natalie's bottom. "You're so hard. Those pants must chafe something fierce."

Kevin seized on the excuse. "Y-yeah. I um... they... ah..."

"Want me to help give you some..." Her lips kissed his ear again. "...Relief?"

"Y-yes," he gasped, then realized what he had said. "W-wait! I m-mean-"

But it was too late. Her fingers tugged down his zipper, and without that, his cock couldn't help but bulge into the open, escaping for only a moment before immediately pressing against Natalie's ass.

"Oh no! That won't do," Luisia said. "All that friction will hurt. Natalie? Would you mind..."

"Mmmm. Not at all."

One of Luisia's hand slid from his and down Natalie's back. With a roll of her shoulders Natalie shrugged off the straps of the leotard, allowing Luisia to tug it down, off her body down past her bottom. Kevin groaned as his cock slid against the warm globes of Natalie's naked ass, a whimper escaping him as the warmth of her body squeezed around his cock.

"There we go. Isn't that better?" Luisia cooed.

It was. Oh, it was so much better. The feel of Natalie's ass lazily grinding around his cock was almost more than he could bear. He gasped, tensing as he tried to resist the insidious pleasure surging through him. Throbbing from his balls. He couldn't focus. Their scents assaulted his thoughts, stirred them to a lather. The lust thumping in his veins filled his mind with thoughts of their bodies. Their softness. Their breasts. He panted. Hot. He realized with a start he was moving against Natalie without thinking, rubbing his cock against her ass, pleasuring himself and mindlessly humping her like a randy dog.

"Kevin," Luisia murmured against his ear.

"Y-yes?" he whined.

"You're so awfully tense," Luisia murmured, her hands running up his arms, his sides, slipping under his shirt. His breath caught with a gasp as her hands stroked his chest. His stomach fluttered as her palms wandered lower. "You need to relax more."

"Mmm. I know a wonderful technique for that," Natalie hummed from beneath him.

"You do?" Luisia murmured as she kissed and nibbled on Kevin's neck. "Mmm. Doooo tell."

"Oh, it's quite complicated. Far easier... mmm... to show him."

"Well, if you say so..."

Kevin nearly fell over as, slinky as a cat, Natalie slipped out from under him and straightened. Before he could register this Luisia had grabbed him and flipped him over onto his back. He hit the floor with a grunt, and found himself looking up as the two lovely beastgirls moved over him. His eyes went down as Luisia straddled his waist, her bathrobe shrugged open, unveiling the fullness of her figure. Naked. Of course she was naked. Kevin stared in awe at the perfect orbs of her breasts, her wide hips smooth and soft. As a shadow fell over his face, and he looked up, just in time to find Natalie move over him, her legs trapping his arms as she crouched down, her ample ass eclipsing the world above, her scent soaking his senses with her nearness.

"Let's help you relax," the leopard girl purred, and lowered herself onto his face.

Kevin found his world blotted out under the softness of Natalie's rear. He moaned as he inhaled, her musk stuffing his head and nose, her fur tickling his skin as her hips slid back, pressing her pussy against his open mouth. He cried out in helpless bliss as he felt the soft folds of Luisia's pussy envelop his cock, swallowing him whole into soft, pink glory.

"Oooooh," Natalie purred as she began to rub herself atop his face, his tongue drawn up and into her lush pussy, licking without conscious thought.

"Mmmmm!" Luisia moaned, the bovine sound of pleasure heralding her beginning to ride him, her pussy squeezing and massaging his cock with wonderful pleasure, her soft hips slapping his groin as she fucked herself atop him, the sounds muffled by the softness of Natalie's ass.

Kevin groaned, lost, adored. Every moment of pleasure threatened to overwhelm him with tactile delight. His arms were trapped. His body pressed down beneath the two ample beauties. He couldn't move. Couldn't escape.
