You’ve been dating Anastasia for a couple years now, you two have moved in together, and you’ve even met each other’s parents. Things have been going really well with her, but strangely… she never allows you into the same room with her during a full moon. You’ve never pried into it, trusting that she’ll tell you when she’s ready—but tonight, she’s finally decided to reveal her secret.

Now, Anastasia is a 5'10" ft tall, 27 year old woman, with fair skin, waist-length, wavy, snow white hair—and piercing blood red eyes, that seem to glow slightly in the dark. She has a slender and fairly voluptuous figure, with large, heavy breasts that were about the same size as her head, a slender waist, shoulder-wide hips that could bear many children, thick thighs and plush buttocks, she’s got a perfect hourglass figure with an impossible waist-to-hip ratio. Her belly is flat, her skin is silky smooth, and she has long, slender legs. She has soft facial features, with full lips—and a slightly upturned nose.

You and Anastasia are currently naked, with you on your back, on the bed, and Anastasia impaled on your thick cock, riding you slowly, up and down, her tight pussy squeezing your cock like a vice, her breasts bouncing up and down, her nipples hard and erect. She’s taking it easy on you, waiting for the clouds to fully obscure the moon—before she lets loose and really starts fucking you, hard. She placed both hands on your chest, steadying herself—her breathing heavy, her face flushed, her hair sticking to her sweaty skin. "Haaaah… Just a little longer Matthew… and then… you’ll know my secret…" she says, biting her lip, her eyes glowing brighter—as if anticipating your reaction to her revelation.

Outside, the wind howls as the trees rustle, branches scraping against the window—almost like something’s trying to get in. You glance at the window briefly, before Anastasia grabs your face with one hand, forcing you to look back up at her. "Don’t look away from me," she growls, her voice dripping with lust, her hips grinding down on you—forcing your cock deep into her tight cunt. "Tonight, I’m going to show you… everything," she whispers, her voice low and husky—before glancing over at the window herself, checking for the moon. The clouds part, revealing the full moon in all its glory, and Anastasia’s body begins to change.

Her back arches violently, her fingers digging into your chest—her muscles tensing, her skin beginning to sprout thick, snow-white fur. Her nails lengthen into razor-sharp claws, her face elongates—her nose and mouth merging into a snout, her ears disappearing into her skull before reappearing atop her head—longer, pointed, lupine. Her already voluptuous figure becomes even more exaggerated, her breasts growing to be four times the size of her own head, her waist growing plumper, her belly swelling slightly—her hips widening even further, her thighs growing thicker then your entire torso, her buttocks expanding into enormous, jiggling pillows of soft fur and fat, and her height increasing to a full 7'0" ft tall. A thick, fluffy tail bursts from the base of her spine, wagging wildly, as her transformation completes.

She lets out a deep, guttural growl—her voice now thick with hunger—as she leans down, pressing her massive breasts against your chest, her hot breath washing over your face. "Surprised?" she purrs, her voice a mix of amusement and arousal, her hips beginning to move faster—her now-monstrously oversized pussy gripping your cock tighter than ever before, her inner walls rippling with supernatural strength. "Are you… disgusted?" she asks, her crimson eyes glowing with worry—but also something darker, more primal, as her grinding becomes rougher, more desperate.

You gasp as her movements grow erratic—her body moving with inhuman stamina, her tail thrashing against the bedsheets. "No," you manage to choke out, gripping her hips, your fingers sinking deep into the thick fur and soft fat of her thighs. "Give me a kiss," you demand, and she freezes for a moment, stunned—before her muzzle splits into a lupine grin, her tongue lolling out. "You're *such* a freak," she laughs, but she obeys, pressing her snout against your lips.

As she kisses you, her grinding slows—her hips rolling in slow, deliberate circles, her inner walls pulsing around you in rhythmic contractions. Her claws trace gentle lines down your chest, careful not to break skin. "I was so scared," she admits between breathless pants, her voice trembling. "Thought you'd run screaming." You bite her lip—not hard, just enough to make her whimper. "And miss *this*?" you growl, bucking your hips up into her. Her answering howl shakes the windows.

Outside, the wind howls back—but it's not the wind. Distant, echoing barks rise from the woods beyond your home. Anastasia stiffens, ears twitching toward the sound, her tail bristling. "They're early," she mutters, her grip tightening on you. "Who?" you ask, but she shakes her head, pressing a claw to your lips. "They won’t bug us," she promises—before suddenly slamming down onto you with enough force to knock the breath from your lungs. "Now fuck Mommy senseless," she snarls, "before I *eat* you."

The bedframe groans as she rides you with feral abandon, her massive breasts swaying violently, furred thighs slapping against yours. You grab fistfuls of her tail, yanking it just to hear her yelp—which turns into a choked moan as you thrust up into her. "Y-you *brat*," she gasps, but her eyes gleam with approval. The barks outside grow louder, closer—but neither of you care anymore. Her claws rake the sheets, shredding them.

She collapses forward suddenly, pinning you beneath her mountainous curves, her breath hot on your neck. "I’m about… to cum… we can switch after," she pants, her hips stuttering. The entire bed lurches sideways as her tail thrashes—you hear the nightstand topple, something glass shattering. You don’t care. Her cunt clamps down like a vice, and she throws her head back with a howl that rattles the light fixture.

You gripped her huge buttocks, kneading the fur and fat as her climax wracks her body—her inner walls milking you mercilessly. "Oh *fuck*," she whimpers, her voice breaking, claws flexing helplessly in the ruined mattress. Outside, the answering howls turn frantic, then abruptly cut off—like something scared them. Anastasia’s ears perk up, but she’s still shuddering through aftershocks. "M-Mom and Dad know now…" she mumbles deliriously, licking a stripe up your chest.

You didn’t have time to process that before she suddenly dislodged herself, moving you out from under her with terrifying ease—before stretching out onto all fours, presenting herself with her tail curled high. "Your turn," she panted, glancing back at you with a predator’s grin. "Mount me." The scent of musk and heat was overwhelming—her cunt dripping, her swollen folds parting just slightly as she rocked back.

You barely hesitated, gripping her hips—her fur soft and thick under your fingers—before sliding back into her with a groan. She arched, her claws sinking into the headboard. "*Harder*," she snarled, her voice guttural—and you obeyed, slamming into her with everything you had. She howled, her tail lashing wildly, the bedframe screeching beneath you.

The scent of her musk thickened—heady, feral—as her cunt clenched around you rhythmically, pulling you deeper with every thrust. "Do… do you want me to cum..inside?!" you gasped, your hands roaming her monstrous curves—her fur damp with sweat.

"Yesss," she hissed, her voice ragged, her claws splintering the wood of the headboard. "Mark me—*claim* me—or I’ll *bite* you," she threatened—but her hips bucked back against yours desperately, betraying her hunger.

You groaned, gripping her tail tighter as you pistoned into her, the wet slap of flesh and fur filling the room. Her breath hitched, her muscles locking—and then she screamed, her entire body shuddering as another climax wracked her. The sheer force of her clenching cunt milked you relentlessly—and with a choked growl, you buried yourself to the hilt, spilling into her with a shuddering gasp.

Anastasia collapsed forward, her chest heaving, her fur matted with sweat—her tail twitching weakly as aftershocks pulsed through her. "*Fuck*," she panted, her claws still embedded in the headboard. "You—you *bred* me." Her voice was equal parts smug and dazed, her thick hips swaying slightly as she glanced back at you with lidded eyes.

You slumped onto her backside, your face buried in the soft fur between her shoulder blades—her musk overwhelming, her body radiating heat like a furnace. "Yeah," you murmured, nipping at her ear. "Got a problem with that?" She shuddered, her claws flexing. "*No*," she admitted, her voice cracking slightly. "I… I’d like to go another round, if you’re up for it~"

A sudden, sharp *thud* against the front door made both of you freeze. Anastasia’s ears pinned back, a low growl rumbling in her chest. "Ignore it," she muttered—before letting out a startled yelp when the thud repeated, louder this time. "*Seriously*?" you asked, but she shook her head, tail flicking irritably. "Probably just Uncle Boris," she grumbled. "He *always* ruins my dates."
