The Eversons weren't aware of it, but the magic had begun to work its powers as they drove along the dusty road. Linda and Debra were the first to be affected, as their larger breasts had begun deflating, becoming flatter and flatter until their bras hung loose in their slightly baggy shirts now. It didn't seem to faze them, with the two even absent-mindedly scratching their flat chests.
Their hands would even drop down to their laps, resting them on the crotches that also happen to be growing for the two. Eventually, their tighter female pants would inadvertently their newly changed male genitals. The only thing indicating their previous femininity was their unchanged body shape and their behavior in body motion.
With the first of the odd changes done, the magic flowed within them to start the next changes. Gray fur began crawling from underneath their clothes, their destinations being their limbs. As soon as the fur reached their hands and feet, earth brown fur grew instead. The fur on their feet caused the next wave of changes as they began to stretch and toes began to push closer together, creating a strange hybrid cross between rabbit's hindpaws and human feet, though it was clear they were much like rabbit feet due to the length nearly being twice as long as their previously human feet. The same happened to their hands, becoming slender and paw-like, yet still functional as hands. As they finished shifting, soft pink paw pads began pushing from their palms and feet.
Fur also continued up their heads, with the front of their necks and lower jaw growing soft white fur instead. This caused their mouths to push out slowly until more fur covered their faces, resulting in short lapine snouts. Their noses followed next, shrinking into small pink rabbit noses and whiskers poking out from their new puffy upper lips. When the rest of the gray fur enveloped their heads, their hair followed as well, becoming the same gray plush as their fur which also covered the backs of their ears. This causing their ears to travel up the sides of their heads to the top, stretching into long bunny lengths where they twitched in delight.
Last, but not least, all their pants began feeling bunched up and crowded behind each of them. It first started as a strange bump just below their waste line, but soon all five of the bunny-like family members had large mounds pushing at the seat of their pants, fluffy white tufts of fur peeking through the tears being created. Finally, all five tails broke free in a loud unified *RIIIP* For a moment, everyone looked up and around in surprise at the sudden noise, before shrugging it off, their new erect tails calming down, leaving them as adorable fluffy cottontails.
The car now contained a family of five male anthro bunnies, but the magic had not finished its work. Like a wisp of wind, their clothes dissolved away, revealing the rest of their changed bodies. White fur created a small area covering the middle of their chests down to this abdomen and crotches. All of them now had furry white sheathes with matching fur balls beneath them.
The car had followed their changes, too. The backs of the seats had opened up holes where their tails can freely twitch unhindered. Their luggage in the back began lessening due to their lack of clothes, until they only had their cameras and their pictures, which also began in content to match their new lapine forms.
All the while as their physical form changes, the magic that kept them oblivious to them also began to work directly at their minds. Their memories and visual thought were adjusted to become lapine while motor skills for their new limbs became natural to them. Shame and embarrassment was lost, considering they feel natural needing only a coat of fur and the meaning of clothes meant nothing to them.
While the magic had left them as a family of male bunnies, their behavior prior had not changed the least with the exception of their male lapine 'heritage'
"Dad! Rick and Sam keep poking me with their sheathes!" Debra complained as the two anthro kits were playfully poking their sheathes at 'his' thighs. "Talk to your daddy, dear. I'm busy driving."
"Daddy!"
Linda looks back, sweetly smiling at 'his' twin kits. "Now boys, it's not polite to poke your brother like that!"
