Yet again, the Goddess Eris waved her hand, and a wave of erotic pleasure went through each of the Habers. The four horse-men grunted and whinneyed in their deep voices, as the group suddenly toppled forth onto all fours. Their large horse-asses were pointed right at the audience, along with their dark, dangling testicles.
The stallion men's hands were changing. Their fingers and already thick nails were fusing together into large clumps, matching those of their transformed feet.
"Whi-heighgh!!", Sandy whinnied. He and the other beast-men looked at their goddess in reverence, as their forearms stretched to meet the length of their bulky legs. The rest of their bodies adjusted to fit their new stances, with necks bulking up and lengthening. Their chests barrelled forth, and more muscle grew on their already buff torsoes, matching those of proper horses.
It didn't take long till Eris's newest changes stopped, and on her altar were now four black-coated stallions. They looked larger than normal horses, with far more muscle than the average equine. They looked at each others beastly forms, and they stamped their hooves in approval. They still retained some human thoughts, but most of their minds were that of a horse's, and the only thing on their mind was love. That seemed evident enough from the long, hard horse cocks jutting below their dark furred bellies.
Eris grinned as she admired her latest creations. "Marvelous, is it not? Fine, beastly bodies with no humanity to chain you. Now, Haber Stallions...show me your love for each other!
They didn't hesitate. First, the four horses dipped their snouts in, and started lapping each other in the mouths; lathering one another with saliva. Then, the stallions started trotting around in a circle, as if they were figuring out how to arrange themselves.
Eventually, the first coupling happened. The buff horse that was once the Haber's son Joshua, leapt onto his transformed father, Jeff. He immediately prodded his cock into Jeff's plump anus, and began pumping away. Behind him, Joshua's former big sister did the same, with Sandy leaping onto his fellow stallion's rear, and mounting him as well. Lastly, Laura jumped onto Sandy, and did the same to his former daughter.
"W-heee! wiheigheigh!" On the altar stage, the stallions fucked away in a single row, bucking their haunches into each other as Eris's reverent followers watched. Their massive testicles bounced with each thrust, and their hard horse-cocks slapped against each other as they pumped in and out of each other's asses.
It wasn't long till Sandy started cumming into Joshua's rectal passage, and Joshua did the same. Laura followed soon after, filling his mate with his seed. At the lower end of the equine fuck-train, Jeff let loose his own seed onto the floor of the altar, as his long penis squirted away like a hose.
"Heigh! W-wheiiighg!", they all whinnied. The orgasm seemed to roll on forever, as they continued humping and thrusting. On her seat, Eris smiled at the fine spectacle.
Satisfied with herself, the goddess waved her hands once more, and the Haber horses' bodies were immersed in light.
When the light dissipated, the Habers were gone. On the side of Eris's altar, however, there were a set of new stone carvings; that of four stallions mounting one another, with heads raised in a silent bellow, and carved tongues hanging out. Jeff's cock was carved quite wonderfully as well.
On the sidelines, Dave grinned. Despite the animal changes, it seems the Goddess Eris had a preference for inanimate transformations too.
"Now here they are, my faithful!" proclaimed Eris, as her followers cheered. "A family now together forever as stone beasts. Their only thoughts now are of eternal pleasure, love for one another, and pride for their selves!"
"But alas, the day passes, and we must continue! Who is next to come forth?"
