"...dare!" Kyle blurted out. Jen was taken by surprise, hoping she could give the same curse back to him.
"Well, I, uh... I dare you to transform me!" Jen blurted out almost equally as fast. As Kyle started talking, Jen started kicking herself. "Damnit, what's he gonna do to me now..." she thought angrily to herself.
"Well, Jen, since you were an ass to me before, and presumably you T&D'd me again to be an ass..."
"Yeah, get on with it," Jen sighed with a stomp her hoof.
"Well, because of that, you'll grow a second Clydesdale stallion's ass."
Jen stood there, dumbfounded. "How could I have been so stupid to give him that power," she thought as Kyle closed the door and left for school.
Jen soon felt a powerful itch as her current horse ass shifted to the side, her human body now at a 45 degree angle to her equine ass. The source of the itch became obvious as an exact copy of her ass started to grow in next to it, 4-foot cock and all. The entire growth took 5 minutes, its finalization signaled by the clacking of two more hooves on the wooden floor. Jen now stood on 4 horse legs, her two Clydesdale asses each meeting her waist at a 45 degree angle. She could feel two identical tails swish behind her, her sense of balance constantly readjusting due to her odd posture and leg setup.
She leaned foward to look at her undercarriages, sighing to see she was now doubly endowed with 2 huge sheaths and 4 gigantic balls. Jen groaned and tried to figure out how she'd walk, moving one leg at a time slowly but surely and trying her best not to trip, since she was unsure if she'd be able to get up if she did. She walked slowly to the computer in the front room, eventually reaching it to see if there were videos of some kind of 6 legged animal like her she could use to figure out how to walk. She found a video of a goat with the same body she now has, and spent all day studying its movements and walking around her house, adjusting to her new form. By the end of the day, she was able to walk quite well.
