Eris waved her giant hand. Instantly, the family's clothes shredded into dust, and vanished, leaving all four family members naked. They glanced at themselves, shy and embarrassed, yet still reverent to the goddess. The youngest teen, Joshua, even sported a little erection from his hairless cock.
"My...what lovely, perfect bodies!", said Eris. "But perhaps we should make them even greater! From you, Habers, I shall take your humanity, your familial bonds...and all sense of shame!"
And with another hand-wave, the family began changing. Heat surrounded them as they all felt aroused, with the men of the family finding their cocks getting hard, while the women felt their nipples popping forward. The Habers all moaned and touched themselves, right in front of the Eris and her worshippers.
Eris enjoyed seeing such devotion from these humans who were once ordinary people. Their emotions flowed from their hearts, and their souls were now pure and clean. All because of what she did. And soon enough, they would be completely hers.
Laura and Sandy felt the first changes. Their clitorises pushed outwards from the top hood of their labias, becoming erect and larger than before. Both mother and daughter groaned as their sexes grew thicker and wider, stretching forth into strange, fleshy sausages as their pussy lips wrapped around them; sealing off their vaginal openings. Underneath, two meaty balloons grew out, and dangled under their groins. These ballooned outwards, and filled with blood as the girls' new organs swelled, causing bulging veins to show on both sides of the swollen orbs. Soon enough, their new penises became rock hard.
"W-whoa...", Joshua uttered, as the youngest of the family saw his mother and sister's new parts. Jeff also blushed as he saw what had become of his two dearest girls.
Then, all four Habers' found their penises swelling and stretching in size. Their tips became bulbous and enlarged, with darker, random splotches coating the flesh. They also saw found more skin between their pubic bones where their shafts connected. Their four cocks had grown so long, they almost matched the length of their arms!
At the same time, their legs changed, becoming longer with slender toes that morphed into hard, black hooves. With this, the Haber family's bodies got taller, especially the teen children, who were reaching a similar height as their parents. Black fur started growing on their skin, spreading like fire along their limbs and stretching torsoes, and also on their swelling buttocks. Their tailbones extended out into tails, complete with horse hairs.
While the fur spread and their torsoes bulked with muscle, the Habers started rubbing their cocks. Joshua started first, with the young teen's puberty-focused mind pushing him to pleasure himself. His family joined in soon after, and they moaned as they fondled their cocks, which were already dripping with precum.
"Ohhh," Sandy moaned, as she rubbed greedily. Her and her family's hands were now coated with light fur, and their fingers had enlarged with big, stubby nails. The teen girl was barely aware that her young breasts were flattening into her chest, and bulking into male pecs just like her mother. Their arms were as thick as those of ancient Greek spartans.
The charcoal-colored fur was now up to the family's necks, which also swelled with meat and muscle. The hair on their heads shifted into a deep bronze, as their ears become furred and pointed. Their faces fattened, and their noses and panting mouths stretched forth.
"Yeeesh...", Jeff uttered, as he and his family's voices went hoarser and deeper. He could barely believe this was happening, that he was transforming into horny beasts with his wife and kids, right in front of a crowd of people. But it was what Eris had willed. And he embraced it.
"Yeeeh-eeeehh-weeeiighghg!!"
The family ejaculated. Just as Eris stated, all sense of bodily shame had left the Habers, as they squatted on their equine legs, and held their spraying cocks with their large, big-nailed hands. They dumped their load right in front of the goddess's feet, as they whinnied with inhuman voices. The crowd of Eris's followers cheered.
Once it stopped, their cocks flopped softly towards the floor, dripping puddles between their hoofed feet. The four new stallion-men grunted, as they took in the sight of each other.
The former mother, Laura, looked at what had become of his kids and husband. They were so beautiful..so powerful...and alluring! Laura breathed in his family's delicious musk, and his mate Jeff did the same.
Sandy stepped up to Laura; the former daughter was now almost as tall as his mother. With no hestitation, the two moved in close, and shared a tonguing kiss with their snouts. Nearby, out of a new instinct, Jeff did the same with his son Joshua, now the size of an adult. They took turns with each other, with no worries about incest whatsoever.
"I see you have taken to my gift well," said the Goddess Eris, smiling as the buff stallion-men turned towards their goddess, holding each others hands in affection. “Ah, but perhaps you deserve a little more! Let us change your loving bonds to something even greater!”
