Light of a Soul

"Bro! I have something to tell you! You can control your gender...ability."

"How?" Soul Light turned to see the blue colt, Soul Break.

"With enough practice and skill, you can change whenever you want! But you gotta change genders within a time period, otherwise it'll change genders without your decision."

"When can we start?"

"I'm sure your marefriend would be glad to see this."

"It's been 4 months man, and she was in the heat back then!...She beat me up."

Soul Break , turning red and teary, cried out laughing that I was beaten by a filly.

"Hey she was really fast you know! She blamed me for taking advantage of her when she was in her first heat!"

"I'm sorry man." Soul Break wiped his tears from his dying laughter. "O.K. first of all, you need to change into a mare right now!"

...how?

Soul Break lighted up his horn and the light beamed into the Pegasus's body. A familiar smoke cleared out and now...a new, but awfully similar being emerged from the smoke. A yellow orange Pegasus with a red and grey mane and tail. SHE stood in a very specific fashion.

"Finally! I'm FREE!" The voice came out even more girly than her appearence.

"Now Soul Light, try to change back."

"So you're his brother. I never imagined you to be this dull and idiotic!"

"WHAT?!?"

The mare opened the door of the red cherry building, and flew up in the sky." Ta ta." She winked.

Soul Blood flew above the sky and circled in tricks...until she was tackled by a streak of the rainbow.

"Soul Light! You will pay for what you done!" Dash grabbed Soul Blood's tail and flung her like a ball on a chain. Soul Blood instinctively avoided a cloud, but she didn't avoid the second cloud. She landed on the puff of fog and water. Dash soared across the sky like a bullet and stopped when she reached the mare.

"You're not Soul Light."

"Yes I am not like that barbarian, but only in color."

"Are you his sister?"

"...No..I am Soul Light."

"Huh?" Dash's face showed obvious confusion.

"I am Soul Blood, Soul Light's more...feminine side."

"But you are still Soul Light!" The cyan Pegasus raised her hoof and connected her left hook into Soul Blood's temple, knocking her out.
