Caroline wasn't able to finish her thought before the buzzer went of and her and Charlie's transformations began.
A massive bump appeared in Caroline's jeans, growing and growing until Caroline's new tail burst out over the top of her jeans. It was long and
colored the same shade of brown as her hair. It was clearly a horse's tail.
Next Caroline kicked off her to reveal feet that were starting to expand and turn into large hooves. Likewise, her fingernails started turning black
and thick, then merged, leaving her with hoof like hands.
Caroline's face pushed forward, developing into fine snout. Caroline's mouth became incredibly numb. Her teeth were reforming to fit a vegetarian
diet. Her lips and tongue swelled into new and larger shapes. Her ears grew more pointed and much larger, sticking out of the top of her head.
Then came the changes to her body. Caroline's previously admired butt was the first thing to grow. It expanded and started stretching her jeans,
popping the seams and destroying her jeans. Her stomach grew wide and her upper arms grew massive, doubling their size in seconds in order to
function as another pair of legs. Caroline's thighs swelled with muscle and tore off the remains of her jeans and revealed a pair of pink lace
panties, much to small for this horse's ass.
Caroline fell to all fours as her torso reshaped. She eyed Charlie; he was in the state position she was, his torn clothing revealing his strikingly
large member. Caroline squealed with internal glee at the sight of it. She didn't know it, but she was undergoing a severe mental shift from human
to horse.
As her body filled with brown hair, Caroline lost more and more of herself to her new equine mind. She began to forget her family, friends, her
fear of horses, and even the game as she became more concerned with things like grazing. The one thing she couldn't forget was Charlie, and her
intense desire to mate with him.
As she finished her transformation into a horse, Caroline shook a couple of times removing the remaining pieces of ill-fitting clothing. Her butt,
still clad in her overstretched pink panties, was managing to attract the leftover flies from Darcy and Peter's challenge. Caroline instinctively
swatted them away with her tail.
She looked at Charlie, who had likewise completed his transformation, and presented her now massive rear end to him. Charlie ambled over and
tore of Caroline's panties using his teeth. As he mounted this beautiful mare from behind, Charlie didn't know why, nor could a horse ever fully
understand this feeling, but he felt an incredible sense of satisfaction in placing his dick in this mare's immense behind.
Though Charlie and Caroline had not solved their riddle during preparation time, it seemed to matter little, as their preexisting chemistry had
solved their challenge for them. Charlie was indeed going to seal the deal Charlie pumped furiously into Caroline for several minutes of intense
pleasure. Upon the moment the pair climaxed, eliciting neighs of joy from the pair, the buzzer rang again, this time with a green light.
As Charlie collapsed on top of Caroline, the pair began too shrink and return to their human forms. Still in the throws of ecstasy, Charlie's penis
was still inside of Caroline's butt when they had reverted fully.
Caroline, still in post-coital bliss, turned to face Charlie, still planted on her back. "I guess you really did admire my rear, huh," joked Caroline
flirtatiously.
The pair quickly realized their nakedness and blushed accordingly, before Tira handed them a blanket to share in covering themselves.
"So, would you care to explain what happened?" yelled Hanna, who, like the rest of the still-human members of the group, was still in shock at the
proceedings.
Caroline bit her lip, looked at Charlie, and then faced the group. "Not going to lie, that was hands down the best sex I've ever had." Charlie
developed a stupid grin on his face.
"I think Hanna meant what happened with the game," clarified John.
"Well, I guess we can confirm that if you complete your challenge, you'll revert back to normal," replied Charlie.
"What do you mean by revert to normal?" croaked Darcy, still oblivious to her changes.
"So," Caroline began, looking at the remaining pairs with a devilish grin, "who's next?"
