As Dustine walked upstairs, she felt another thought press against her mind. Not consciously sent by Krissi, but a strong desire. She smiled as she turned it over in her mind. Oh, naughty girl. She grinned, as more thoughts and wants drifted in. Desires to be cared for, smothered by Dustine in all sorts of ways, wants to be mothered and coddled. A little strange, seeing as Dustine was Krissi's actual mother, but nothing about their incestuous relationship was normal. Dustine narrowed her eyes at the bathtub as she tugged on her long, hard nipples.
Two streams of gold shot out of them, quickly filling the bathtub with her ambrosia. The other two hands fondled her pussy as she tossed her head back and let out a long whinny of pleasure. Her milk, pale gold and faintly glowing as it flowed into their bath, felt so good as it sprayed from her heavy breasts. The unicorn watched with lust as the bath filled to the brim with her powerful, magic essence. It smelled sweet, but the scent was inextricably infused with her own musky scent. A perfect way to remind her daughter that she was the one in charge, and claiming Krissi's body as her own. A flash of light from her horn, and pink rose petals scattered themselves across the golden surface. Another flash lit the dozens of candles in the room, bathing everything in a soft, romantic light. Good, everything was perfect.
As she descended the stairs, she had to duck her 8-foot body before it knocked into the ceiling above. She silenced any words Krissi was about to say with a deep kiss. Her muzzle was huge compared to the tiny human's face, but it only served to let her dominate her daughter's mouth even more. As they broke away, she stared deep into Krissi's eyes. "Darling, your bath is ready," she whispered, running two of her arms down her daughter's body, feeling up every curve. Her two other hands grasped Krissi tightly and wrapped her against the unicorn's immense, Amazonian form. She weighed nothing to the hyper-muscular anthro. Her incredible muscles clutched the human tight, promising to always keep her safe in her mother's arms.
Dustine gently tore the clothes from Krissi's body and lowered her into the bath. Already, her milk was getting to work revitalizing her daughter's body. Any flaws in Krissi's skin smoothed out as excess fat melted away, leaving her daughter fit and sexy. The 8-foot Amazon drank in the human's body, lusty thoughts brewing in her mind. If she had been concentrating, she might have heard someone whisper in her ear, urging her to become more forward, more sexual, more dominant. She might have noticed how her thoughts changed from serving her daughter to claiming her, to ravishing her body the way that no man or woman could do. Darker, Krissi urged. You're my mother, and you would never let anyone dare lay their hands on me. I am yours, and the only one who should ever be able to touch me is you. All Dustine heard was Krissi's overwhelming urge to be fucked.
Steam huffed from her equine nostrils as she glared down at her little pet, mewling and writhing in the bathtub like an animal in heat. If that was what Krissi wanted, then Dustine would be a beast for her. With a flash, the bath grew larger, until it was larger than an Olympic swimming pool, easily accommodating her gigantic body. She pressed Krissi's shoulders back with two tree-trunk arms as she slid into the milk herself, and clamped her legs around Krissi's. "You wanted me?" she purred, not noticing as her voice dropped a few octaves to a deep, lusty growl. Her teeth grew gleaming sharp, white daggers in her otherwise beautiful muzzle. A long, black tongue snaked out of her lips, and licked across Krissi's face, wrapping around her throat. "Darling, your thoughts are all too clear to me."
She leaned in close, pushing her tongue down Krissi's ear canal, making the girl squirm beneath her immense body. As her two arms pushed down, the other two reached out and cupped her daughter's breasts in her huge hands, noting how tiny they were in comparison to her own beanbag-sized pairs, all six of them with nipples hard and long as erect cocks. "You want Mommy's huge body. Say it. Say you want me."
"I... I want you," Krissi whimpered, as Dustine growled. Her tongue unwound itself from Krissi's ear, and instead snaked down to her own pussy. She leaned back, allowing Krissi some room as the immense unicorn anthro licked her cunt.
"Ugh, you make your mother so wet, sometimes," Dustine groaned. Her tail swished in the golden waters behind her. Something rumbled within her, and Krissi watched as her mother's enormous abs flexed and crunched together as she unloaded into the milk, feeling her girlcum flood out warm around their bodies, tendrils of the dark seed staining the milk. A sudden flush of heat raced through her, and Krissi suddenly felt herself growing even hornier. Her fault, for allowing Dustine's cum to have aphrodisiac qualities. Suddenly, the human girl stood up and walked towards her mother. Dustine watched her with hypnotic eyes, like a predator stalking its prey, as Krissi ran a hand across her silky fur and impossibly solid muscle. Her nipples twitched as the girl rubbed her breasts. The unicorn anthro arched her back, bracing herself with her arms against the bottom of the pool as her body grew even larger, packing on pounds of muscle - not from Krissi's mind but from the enhancing properties of her own milk, which had begun to flow down her body from her six huge boobs, each an endless wellspring of the golden liquid. Dustine roared and flexed as she took up more and more space, rising higher and higher towards the ceiling, which grew higher with a flash of her now wickedly sharp unicorn horn. She was huge - four feet taller, which Krissi quickly rounded up to the full 20 feet she deserved. Each inch of her was tight and musclebound, boulders forming under each inch of plush white fur. A throaty growl rumbled in her chest.
Something stirred in the water. Krissi gulped as it began to peek above the surface, a flat head with a dark eye that winked as it rose higher and higher. The head was followed by a shaft, monstrously thick and large. It towered over Krissi, dwarfing her body, eight feet of thick, throbbing horse cock. Drips of another golden liquid splattered into the water and Krissi's hair. Viscous, musky pre-cum, just a taster of what was to come.
Quick as a snake, Dustine pounced and pinned Krissi to the wall, hands roaming over her tight little body. Krissi gasped as the Amazon dominated her, twisting her this way and that as she desperately groped every inch of flesh that she could get her huge paws on. Her tongue invaded Krissi's throat, the thick, meaty tentacle stoked by the muscles in the human's neck. The 20-foot unicorn pressed down on her, eyes wild and lustful, baring her sharpened fangs that seemed so out of place in the ethereal beast's mouth.
Then, suddenly, Dustine reared back, and Krissi felt something poke at her entrance. "Oh, god, no," she breathed. "Mom, you can't really be thinking of that!"
"Why not?" Dustine purred, eyes narrowed. "You want it. I know you want it, Mommy knows all your darkest desires, after all. Mommy just wants to claim your little body and make sure it's ruined for any other person, okay? I'm going to fuck you like you deserve."
"But it will never fit!"
"Mommy still has a few tricks up her sleeve, darling!" True, the glans that rubbed up against Krissi's slit was far wider than the human's body, but it was beginning to shrink. Dustine's grip on Krissi tightened, her eyes scrunched tight in concentration. Her horn glowed brightly. Suddenly, her whole body surged smaller. She began to groan, a grimace clear on her face as her body squashed and compressed with each throb of her enormous cock. The huge futa shrank, muscles rushing back into her body. Everything became smaller, but even more attractive as this monstrous, feral unicorn receded into a simple, 7-foot amazonian form. Her muscles were lithe and trim. Her eyes sparkled with desire. As she slowly swayed towards Krissi, it seemed as though every single movement had been accentuated and exaggerated to become the most sexy thing Krissi had ever seen. The floor shook with her every twitch, but Krissi paid it no mind, eyes trained only on the hypnotic, hyper-sensual things her mother was doing.
Her four arms stroked down Krissi's body, before one of them found her cock. It had shrunk, but it still stayed ridiculously large, at a full 3 feet hard. Krissi still wasn't sure she could take it all, but she didn't think she had a choice. Dustine may have shrunk in size, but below the surface were muscles the same mass, and a body just as heavy and powerful, compressed into a more manageable size. Her fingers dug into Krissi's sides as she lifted the girl and stroked her hair at the same time. "Hush now, Mommy's going to fuck you silly."
That was all the warning she got before she was lifted out of the water and violently speared down onto the head of Dustine's thick cock. She shrieked as half the length filled her up, pressing right against the limits of her vagina. Dustine glared down at her. She was raised again, and brought down harder. More of the shaft slotted inside her, excruciatingly painful as she flew past her limits. Stars danced in front of her eyes. And yet, it somehow managed to be the most pleasure she'd ever felt. "M-more," she whimpered, as Dustine jammed more and more cock inside of her. "Please M-m-mommy~ I want to be filled!"
"Oh, you will, baby," Dustine breathed, baring her fangs. She drove her cock in, fitting a full 2 feet into her daughter. She lifted her nipple to Krissi's mouth as she sat there, speared on her length. "Drink up, little girl, and maybe you'll get some more."
As Krissi gulped down her mother's sweet ambrosia, she felt the pressure against her pussy lessen. She looked down, finding her skin stretching, far more elastic and flexible than it had ever been. She gasped as she began to slide along Dustine's dick, finding more and more slotted inside of it. A fog began to overtake her brain, leaving only her thoughts of Dustine untouched. "Mommy? W-wha're you doin' ta me?" she slurred through the lusty haze.
"Shh," Dustine whispered, carding one hand through her daughter's silky hair. Another hand pressed up against her tight tummy, feeling the imprint of her huge cock through the stretched muscle. "I'm just making sure you will always be mine."
"Well, that's ssssilly," Krissi giggled. "I'm y-your daughter right? You oh- own me!"
"That's right," Dustine hissed, a feral grin spredding down her muzzle as her tentacle-like tongue flickered across Krissi's face. "I own your body. I own your mind. Mommy will take care of her little girl, so long as she co-operates."
Krissi's mind was so addled with lust, she didn't even notice that she was shrinking in her mother's arms, nor the hungry glint in her mother's eyes. Krissi began to regress to a younger version of herself, even as she stretched more and more over her mother's cock. It felt so perfect, fit so right inside her. The only way it could get better is if Dustine had another cock.
She gasped as Dustine's second shaft pressed up against her asshole. Dustine smiled wolfishly as she clutched her little 14-year-old in her hands and efforlessly slammed her down again and again onto her cocks, their 3-foot lengths slotting right inside of her. She began to build up a rhythm, pumping harder and faster into Krissi, feeling her daughter mewl and writhe beneath her huge body. She let go of her form, and with each thrust, Dustine began to extend back up to her true 20-foot size. Inside Krissi, the shafts grew thicker and larger. Her body stretched so tight that her skin began to come transluscent in places, showing every throbbing vein through her skin as Dustine fucked her more than any man ever could. As she slammed down into the base of Dustine's giant horse cocks, she kicked her legs out into Dustine's balls, large as a small car, and felt the leathery muscle that protected them ripple and quake with the impact.
Dustine began to roar, her arms trembling despite their immense strength, and Krissi closed her eyes in anticipation. With a shudder, and a loud whinny, Dustine came inside Krissi, inflating her stretchy innards until she looked like a human balloon. Her head lolled back, and Dustine caught her lovingly. It seemed the poor human had passed out. Dustine, on the otherhand, had been gifted with near-infinite stamina, and no refractory period. The double-dicked anthro climbed out of their swimming pool bath, and gently laid Krissi to rest in her bed, kissing the rotund girl goodnight and tracing her tongue over her unconscious body, letting the taste of her daughter linger.
Then, she headed back to the bath. She had not been satisfied, and it would be a waste not to use all that lovely milk to give herself a good time.
