Here's my process and the resources I used:

1. Gen the starting image. I used a local install of Reforge and the model 3WolfMondAI-LastSDG which specializes in realistic looks. (https://huggingface.co/Xeno443 - all of the models here are good, some of the best furry SDXL models)

2. For the video gen I used the WAN2.2 WAN 2.2 I2V 14B Lightspeed (S) High/Low models from https://civitai.com/models/1981116?modelVersionId=2388548 . I used the ComfyUI workflow from the same creator at https://civitai.com/models/1823089 .

3. This is actually multiple video clips edited together. I used the "Extract Last Frame" function in that workflow to get the final frame for each video and use it as the starting frame of the next one.

4. For editing the clips together I used Capcut (https://www.capcut.com/) which is free, though I was disappointed by the ad spam and audio import bugs so any other video editor should work too. The audio I got from https://freesound.org/ and https://www.voicy.network/ . The music came from https://pixabay.com/music/search/-sex/?mood=sexy .

5. That's it! For a few hours of work and no cost beyond electricity you can create your own furry porn videos. We certainly live in interesting times!

The dim glow of the moon filtered through the cracked blinds of Rouge's lavish penthouse lair, high above the bustling streets of Station Square. The air was thick with the scent of exotic perfumes—jasmine and vanilla mingling with the faint, metallic tang of stolen jewels scattered across her vanity. Rouge the Bat lounged on her king-sized bed, her voluptuous form draped in a sheer black negligee that clung to her curves like a second skin. Her huge breasts, full and heaving with each breath, strained against the fabric, the soft white fur of her cleavage spilling over the lace edges, nipples already pebbling from the cool night air. She stretched languidly, her wings fluttering slightly, sending a whisper of wind through the room. It had been a long day of heists and espionage, and she craved something more... primal to unwind.

A soft knock echoed at her door—timid, almost hesitant. Rouge smirked, her ruby-red lips curling as she recognized the rhythm. "Come in, foxy," she purred, her voice a sultry velvet that dripped with invitation. The door creaked open, revealing Miles "Tails" Prower, now fully grown into adulthood after years of adventures. He stood there in the doorway, his twin tails twitching nervously behind him, his golden fur catching the moonlight. Gone was the boyish innocence; he was taller now, lean and toned from tinkering in his workshop and flying through chaos, but his blue eyes still held that spark of genius—and tonight, a flicker of desire he'd been hiding.

"Rouge? You... you wanted to see me?" Tails stammered, stepping inside and closing the door with a click that seemed to seal their fate. His voice was deeper than she remembered, a husky timbre that sent a shiver down her spine. He adjusted his goggles on his head, trying to play it cool, but his cheeks flushed under his fur as his gaze inevitably drifted to her chest. Those massive breasts of hers—each one easily the size of a melon, soft and jiggling with her slightest movement—drew him like a magnet.

"Oh, sweetie, I always want to see you," Rouge replied, batting her long lashes as she patted the bed beside her. "You've grown up so much since our last little team-up. Come closer—let me get a good look at you." She shifted, her hips swaying seductively, the negligee riding up to reveal the smooth, pale skin of her thighs. The room filled with the soft rustle of silk against fur, and Tails could smell her arousal already—a musky, intoxicating sweetness that made his heart race.

He approached cautiously, sitting on the edge of the bed, his tails curling around him like a protective barrier. But Rouge wasn't one for barriers. She leaned in, her breath warm against his ear, whispering, "You've been eyeing me for years, haven't you? All those glances during missions... I know what you want." Her gloved hand trailed down his arm, fingers tracing the muscles beneath his fur, sending electric tingles through his body. Tails swallowed hard, the taste of anticipation bitter-sweet on his tongue.

"I... I have," he admitted, his voice cracking slightly before steadying. "You're incredible, Rouge. So confident, so... beautiful." Emboldened, he reached out, his hand hovering before gently cupping one of her enormous breasts. It overflowed his palm, soft and warm, the weight surprising him as he squeezed lightly. Rouge gasped, a throaty moan escaping her lips, the sound vibrating through the air like a siren's call. "God, they're even bigger up close," Tails murmured, his thumb brushing over her nipple through the fabric, feeling it harden instantly.

Rouge arched her back, pressing into his touch, her wings unfurling slightly with a leathery flap. "Mmm, that's right, baby. Feel them— they're all yours tonight." She pulled him closer, their bodies pressing together, her breasts squishing against his chest like plush pillows. The friction sent waves of heat through her, her core aching with need. She could feel his heartbeat thundering, matching her own, and as she nuzzled his neck, inhaling his clean, earthy scent—like fresh oil from his inventions mixed with wild fox musk—she let her hand wander lower.

Tails tensed as her fingers brushed over his crotch, expecting the usual modest bulge. But what she found made her eyes widen in genuine surprise. "Oh my... Tails, what have you been hiding?" she breathed, her voice laced with awe and hunger. Beneath his pants, his cock was massive—throbbing and straining, easily twice the size she'd imagined for someone so unassuming. She palmed it through the fabric, feeling the girth, the length that pulsed hotly against her hand. And lower still, his balls—huge, heavy orbs that filled her grasp, swollen with pent-up desire. "You're hung like a stallion! How did a cute little inventor like you end up with such a monster?"

Tails chuckled nervously, but there was a newfound confidence in his grin. "Genetics? Or maybe all that chaos energy from the emeralds... I don't know, but I've always wanted to show you." He leaned in, capturing her lips in a kiss that started tentative but quickly deepened. Their tongues danced, tasting each other—hers sweet like stolen candy, his with a hint of mint from his workshop gum. The wet smacks of their mouths filled the room, punctuated by Rouge's soft whimpers as he kneaded her breasts more firmly, pinching her nipples until they ached deliciously.

Rouge broke the kiss, panting, her cheeks flushed. "Strip for me, big boy. I need to see it all." She watched hungrily as Tails stood, shedding his clothes with growing eagerness. His shirt came off first, revealing a surprisingly chiseled torso, fur matted slightly with sweat that glistened in the low light. Then his pants, sliding down to reveal his enormous cock springing free—thick as her wrist, veined and throbbing, the head already leaking precum that dripped in a sticky trail. Below, his balls hung low, massive and full, swaying with each movement like pendulums of promise. The sight made Rouge's mouth water, her pussy clenching in anticipation, the scent of her wetness now overpowering the room.

"Damn, Tails... you're going to ruin me with that," she whispered, licking her lips as she shrugged off her negligee, her huge breasts bouncing free. They jiggled hypnotically, nipples erect and begging for attention, the soft fur around them damp with arousal. She cupped them, offering them up like treasures. "Come here and let me taste you first."

Tails groaned, the sound deep and animalistic, as he climbed back onto the bed. He positioned himself over her, his massive cock hovering near her face while he buried his muzzle between her breasts, inhaling their soft, perfumed scent. His tongue flicked out, lapping at one nipple, the taste salty-sweet as he suckled, drawing moans from Rouge that vibrated through her chest. Her hands roamed his body, one stroking his length—feeling the heat, the velvet skin over steel hardness—while the other fondled his huge balls, rolling them gently, feeling their weight and the way they tightened under her touch.

"Oh fuck, yes... just like that," Rouge gasped, her voice husky as she guided his cock to her lips. She kissed the tip, tasting the salty precum, then took him in slowly, her mouth stretching around his girth. The sensation was overwhelming—hot, throbbing flesh filling her, her tongue swirling around the head as she sucked, the slurping sounds lewd and echoing. Tails thrust gently, his hips bucking, while his hands massaged her breasts, squeezing them together around his face as he licked and nipped.

But Rouge wanted more. She pulled back with a pop, strings of saliva connecting her lips to his cock. "Not yet, lover. I need you inside me." She flipped them over with surprising strength, straddling him, her wings casting shadows as she positioned her dripping pussy over his massive length. The heat between them was palpable, her juices trickling down onto his balls, making them glisten. Slowly, she lowered herself, gasping as the head breached her entrance, stretching her wide. "Ahh... so big... you're splitting me open..."

Tails gripped her hips, his fingers digging into her soft fur, the touch firm and possessive. "Rouge... you feel amazing... so tight..." Inch by inch, she sank down, her huge breasts bouncing with each movement, slapping against her chest with wet smacks. The fullness was exquisite, every vein rubbing her inner walls, sending sparks of pleasure through her body. She began to ride him, slow at first, the bed creaking under them, their mingled scents—sweat, musk, arousal—thick in the air.

Faster now, her moans growing louder, dialog turning to filthy whispers: "Fuck me with that huge cock, Tails... make my tits bounce..." He obliged, thrusting up to meet her, his balls slapping against her ass with rhythmic thuds, the sensation building, coiling tight in her core as she ground down, clit rubbing against his base. The climax was approaching, her body trembling, breaths ragged—

The room seemed to pulse with their rhythm, the air heavy and humid, saturated with the raw, animalistic scent of sweat-soaked fur, Rouge's sweet jasmine perfume now laced with the thick, musky aroma of her dripping arousal, and the sharper, salty tang of Tails' leaking precum. The bed groaned beneath them like a living thing, springs protesting every powerful thrust as Rouge rode him harder, her massive breasts bouncing wildly with each downward slam. They slapped against her chest with wet, fleshy smacks—soft, heavy orbs that jiggled hypnotically, nipples dark and swollen, glistening with Tails' earlier saliva.

"Fuck… Tails… deeper… give me every inch of that monster," Rouge gasped, her voice hoarse and trembling, wings half-spread and trembling with the effort of holding herself upright. Her gloved hands braced on his chest, claws digging into his golden fur as she ground her hips in slow, deliberate circles, feeling the thick ridge of his cockhead drag along her sensitive inner walls. Every vein pulsed against her clenching pussy, stretching her to the absolute limit. The stretch burned so deliciously that her eyes fluttered, half-lidded with lust.

Tails' huge balls—swollen, heavy, and drawn tight against his body—slapped rhythmically against her ass with each bounce, the sound lewd and wet, like ripe fruit being smacked together. He could feel the pressure building inside them, a deep, aching fullness that made his toes curl and his tails thrash wildly behind him. "Rouge… you're so fucking tight… squeezing me like you never want to let go," he growled, voice low and ragged, nothing like the shy fox she once knew. His hands gripped her hips hard enough to leave faint bruises under her white fur, guiding her movements, forcing her down harder.

Time seemed to slow as the edge approached.

Rouge felt it first—a tightening coil low in her belly, electric and relentless, spreading outward in slow, molten waves. Her pussy fluttered around his girth, walls rippling in involuntary spasms that milked him from base to tip. She threw her head back, a long, throaty moan escaping her ruby lips. "Oh god… oh fuck… it's coming… I can feel it building… so fucking deep…"

Tails' cock throbbed violently inside her, swelling even thicker as his own climax neared. The head battered her cervix with every thrust, sending sharp jolts of pleasure-pain through her core. His balls churned visibly, the skin taut and shiny, heavy with the sheer volume of cum he was about to unleash.

Rouge's rhythm faltered, hips stuttering as the first true wave hit her. Her whole body seized, muscles locking tight. "Tails—! I'm—I'm gonna—!" Her voice cracked into a high, desperate whine.

And then she shattered.

The orgasm crashed through her in excruciating slow motion. Her pussy clamped down like a vice around his massive shaft, spasming in powerful, rhythmic contractions that seemed to last forever. Each pulse squeezed him so hard he could feel the individual ripples traveling up his length. A gush of her slick heat flooded out around his cock, soaking his fur, dripping down his balls in hot, sticky rivulets. The wet squelching sounds grew obscene, echoing off the walls.

Rouge's vision whited out for a heartbeat. Her huge breasts heaved violently, bouncing with the force of her convulsions. Her nipples tightened to painful points, every nerve ending screaming. She screamed his name—"TAAAIIIILS!"—the sound raw and primal, tearing from her throat as wave after wave ripped through her. Her wings snapped wide, feathers trembling, and her claws raked down his chest, leaving red trails through his fur.

Inside her, Tails felt the dam break.

His cock pulsed once—hard, thick, unmistakable—and then erupted.

The first jet of cum blasted against her cervix with such force that Rouge gasped, feeling the hot, thick spurt deep inside her womb. It was scalding, viscous, and impossibly voluminous. Another pulse followed immediately, and another, each one flooding her with more seed than she thought possible. She could actually feel her belly swelling slightly from the sheer amount, the pressure building as gallon after gallon poured into her.

"Oh fuck… oh fuck… it's so much… filling me… so fucking hot…" she whimpered, voice breaking as she ground down, trying to take every drop. Her pussy milked him greedily, spasming around his throbbing length, coaxing out more and more. The sensation of being so utterly filled—stretched, claimed, overflowing—pushed her into a second, even more violent orgasm. Her body shook uncontrollably, breasts jiggling wildly, nipples brushing against his chest fur with every tremor.

Tails groaned—a deep, guttural sound that vibrated through both of them. "Rouge… take it… all of it…" His hips bucked upward in slow, powerful thrusts, each one forcing another thick rope of cum deep inside her. His balls contracted visibly with every pulse, emptying themselves in long, endless spurts. The excess began to leak out around his shaft despite her tight grip, white cream bubbling and dripping down her thighs in slow, creamy trails.

Finally, after what felt like an eternity of endless release, Tails' cock gave one last massive throb. He pulled out with a wet, obscene pop—his still-hard length glistening with their combined fluids, veins pulsing, head flared and dripping.

Rouge collapsed forward onto his chest, panting, trembling, her pussy gaping slightly and clenching around nothing, a thick stream of his cum immediately pouring out of her and pooling on his groin.

But he wasn't done.

Tails gripped his massive, slick cock and stroked once—twice—hard and fast. The first powerful jet shot out, arcing through the air and splattering across Rouge's huge breasts in a hot, sticky rope. It landed across both mounds, thick and white, clinging to her soft fur and dripping slowly down the deep valley of her cleavage.

She moaned, eyes half-lidded in bliss. "Yes… paint me, baby… cover me…"

Another spurt hit her left breast, coating the nipple completely, the warm cum sliding over the sensitive bud and making her shiver. A third rope landed on her stomach, pooling in her navel. Then another across her face—thick strands catching on her cheek, her lips, even her eyelashes. She opened her mouth instinctively, tongue flicking out to taste the salty, musky flavor, humming in pleasure.

Tails kept stroking, milking every last drop. Rope after rope painted her—across her heaving breasts, down her toned stomach, over her thighs, even catching in the soft fur between her legs. Her body glistened with his release, the thick white cream contrasting beautifully against her black-and-white fur. The scent was overwhelming—salty, potent, primal—mixing with her own arousal until the entire room smelled of raw, uninhibited sex.

Finally, his cock gave a few weaker, twitching spurts, dribbling the last of his load onto her lower belly. Tails collapsed back against the pillows, chest heaving, tails limp and twitching.

Rouge lay atop him, utterly covered, utterly spent. She dragged a gloved finger through the thick cum on her breasts, lifting it to her lips and sucking it clean with a slow, deliberate moan. "Mmm… you really did ruin me, foxy," she purred, voice hoarse and satisfied. "And I loved every second of it."

Tails managed a weak, breathless laugh, pulling her down for a slow, messy kiss—tasting himself on her tongue, feeling the sticky warmth of his cum smear between their bodies.

The room fell quiet except for their ragged breathing, the soft drip of cum hitting the sheets, and the faint rustle of her wings as she folded them around them both like a cocoon.
