Ginny Weasly had just finished breakfast, she had her first class off as snape was in a meeting in london. so she was walking around the hogwarts grounds, unknown to her that a ball of shemal energy was hedding her way. Ginny found Luna sitting by the lake, she was tossing rocks into the water, humming a tune that Ginny did not know. "hello Ginny" she said not looking at her. startaled Ginny walked over and sat down. "how did you know i was here" she asked Luna. luna tossed another rock into the water. "i can here your footsteps as you.." she stoped talking as she looked up, Ginny fallowed her eyes and found what looked like a yellow ball of light comming toward them. Ginny grabed her wand just as the light hit...and went throw them both, nocking them bouth onto the ground.
a few min later ginny awoke and sat up, "what was that, was that a spell, or something from a magical creacher" she said outlawd. when she looked at luna she got a shock, Luna was naked, her breasts where GG size and she had a male cock growing bigger and bigger, when Luna sat up she was smiling, "LUNA, whats happing to you" Ginny cryed. Luna smiled "the same is happing to you" she replyed as she let out a moan as her cock was now 4 feet long. Ginny looked down and found that she two was naked, her breasts where CC size and growning. "ohhh yesss" said Luna as a load of cum shot out of her big cock. she stood up and walked closer to ginny. "come on Ginny dear, your allmost there" she said as she watched as Ginnys Breasts became GG, then her cock shot to 3 feet then 4, thats when Ginny let out a loud cry as she shot out a load of cum, her mind transformed into a shemal, she now knew what was needed to do and what she was, both ther cocks started to glow blue. "well, lets say we go spread our new power around" said Luna. Ginny giggled and replyed we shound get harry and Hermione first as thay could find a way to stop us if we left them alone, "fine, but i Get harry" said Luna.
