Connor didn't reply, but still watched in front of him. He saw Nicole stop petting the zebra, still balancing perfectly on her hooves. She placed one hand on one of her friends shoulders before bringing one of her hooves up and resting it on her knee. She picked a thick piece of dirt out of her hoof and threw it on the ground. After cleaning herself she placed her hoof back down and backed up to give someone else a turn.
"Ah, a volunteer.", the voice said in Connor's head. Connor winced. "Again."
Connor closed his eyes and opened them seconds later.
There was Abby, another of the girl's basketball team, stepping up to the zebra, though from the back she looked slightly different. Connor saw the thick black tail extending out from above the waistband of the girl's shorts, idly swishing side to side. Abby looked behind her for a moment, spurred by the sensation of wind behind her. When she did though she stopped to look carefully at the tail behind her.
"Very funny guys, who stuck the fake tail on me?", Abby asked, looking behind her.
Nicole laughed. "Pretty funny, Abby. I wish they sold props that realistic."
"Wha...", Abby said, confused at her friend's reaction. She looked back down again, and carefully looked at the center of the tail, and continued toward her back, where it seamlessly fused into her exposed lower back. She gasped and quickly brought a hand and grabbed the base of her tail, trying to pull, but only felt pain.
Nicole grew concerned at her friend's actions. "Abby, what's wrong."
"I... uh...", Abby stammered in a panic. As her feet shifted as she turned, she became aware of a new sensation in her shorts. Her panties were suddenly very tight. There was a lump of flesh between her thighs and she was feeling every bit of it. Realizing what was going on, she broke away from her friends and rushed to a nearby restroom. Nicole looked at her and followed behind, clopping loudly before stopping outside the restroom in case her friend needed her.
Inside the stall, Abby sat on the toilet and pulled down her shorts. As they fell to her ankle, she felt light-headed at seeing what she now had between her legs. There, contrasting her pale flesh was a jet black flaccid sheath and pair of balls the size of a softball. She felt the weight pull at her crotch heavily. Her blue panties were pulled to the side, the center now stuck between one of her massive testicles and her thigh. She reached down with one hand and hefted the balls, reaching underneath them and feeling the smooth flesh, now knowing her vagina was gone. Her hand kept going, hoping with every movement the leathery feeling black flesh would give way again to her smooth, soft skin. Her eyes went wide as her fingers found her new, thick asshole. The zebra had given up everything between it's legs, it's tail and even it's asshole to the girl.
Realizing she wasn't dreaming, Abby stood and pulled up her shorts, almost retching at her new form. She was red in the face and her heart rate was through the roof. She left the bathroom, slowly, almost like she was seeing light for the first time. As she looked forward, she saw the zebra again, and saw from the side it clearly didn't have a tail anymore.
It didn't take much for Abby to add two and two together, and she mindlessly walked past Nicole toward the zebra, moving to get a better look behind it. Nicole clopped behind her, moving back toward the group, trying to get her friend's attention. Abby neared the rear of the animal and looked at it's backside, seeing only a round pink area of flesh where it's tail should be fore looking lower and seeing the tight pink pucker, leading down to what had been her vagina, her small amount of brown pubic hair looking even more bizarre between the black and white legs.
Even moving was disturbing to her, now. She felt every shift of the heaving package between her legs.
The park employee spoke. "So Jeffrey here isn't exactly 'equipped' like other zebras, as you can maybe tell. He's a bit different, but he's just as much of a zebra as any other. Thankfully, due to his uniqueness, he is certainly well-behaved around Priscilla, our zebra mare currently in heat."
The group looked intently at the zebra, not seeing anything wrong with the zebra having parts from the teenage girl's in front of him. Nicole nudged Abby's shoulder. "Come on, Abby. Let's head over and check out those other zebras. I need to get moving again, maybe they'll have some dirt beside the paths for me to walk on, all this pavement is started to get annoying."
"Yeah, Nicole, I hear you.", Abby said as she was always accommodating of her friend's needs. Sometimes Abby wondered why Nicole even was allowed on the basketball team at all, to be honest, her hooves tended to scuff the court horrendously.
Connor had only seen Abby's tail, her shorts baggy enough to conceal her new package well. It was only when Connor and Sabrina walked past the zebra that Connor looked behind him and saw the very human, and very female equipment between it's legs.
Connor shook his head, almost in guilt as he and his friend continued on.
