The die rolled off the table and bounced across the floor, coming to rest at the other side of the room. "What did you get?"
Karyn got up and looked down at the die. "Two, that's-" A sharp stab of pain hit her stomach, driving her to her knees. She threw out her chest and arched her back as her spine lengthened. Karyn pulled down her pants to allow a long bushy tail to burst out of her ass.
"Centaur." Joe clenched his teeth, his legs were in so much pain. Fortunately the magic of the ring made their clothes dissapear, freeing them to observe their changes. Fur spread down Joe's legs, he rubbed his hands against it, feeling his skin push out as new muscles grew in. Only the table kept him from falling over as his feet turned into hooves.
Karyn could not push herself up, her legs had already changed too much. Again she streched her back as she felt it lengthen, eventually climbing onto her new front legs. She fearfully held out her arms to balance, unsure of her new limbs.
As their new lower bodies filled out, their human half underwent changes. Joe's hair grew out into a thick mane, both of them felt the hair spread down their backs. Joe saw Karyn's hair blonde hair change colour slightly to match her palomino body, while she saw his turn toa glossy black.
Their ears itched as the tips pointed and grew out. Their skin itched slightly as it touched up, to match the thick hide of their horse bodies. And there was a subtle shift in their minds, as new thoughts and instincts formed, as their new animal natures grew in.
