Jon had always chosen the same character ever since he realized that it annoyed Mickey to lose against them and he chose her again now. Only realizing what he'd done when it was to late, he had chosen Princess Peach!
Before he choose Peach, his body was still his own but now it felt like it was transforming in to a new shape. He gasped as he felt himself getting smaller, though his backside seemed to not to be affected. He noticed something in front of his face. It was long blonde hair. He looked down and found that his clothes started to get tighter on him and turn pink. He felt his chest burn and watched in horror as breasts pushed against his top. He felt a strange sensation of pleasure as his nipples expanded and rubbed against the pink cloth. He pulled in hands up to feel them and noticed that his arms where hairless and much more skinny now. Next he felt pain in his abdomen as his waist shrunk and his bottom expanded.
What happened next scared him the most as he felt his penis shrink and pull inside him taking his balls with them. He grabbed his stomach again feeling more pain as he grew a womb. Now he was a she complete with a soft bouncing boobs and a silky vagina.
She was about to shout out, when with a roaring sound her clothes changed around her. Her jeans pulled together at the legs and changed material becoming an ultra tight silk skirt. At the same time her trainers become red high heels and when she struggled to move she fell over, bracing herself with her now gloved hands. Her top's arms bloomed out and became frilly and the body became a corset. Her socks began to grown in to stockings and her underwear tightened up in to tiny silk panties. Unsteadily getting up she felt a weight on her head which she realized was her crown.
Looking down at herself Jon was now Princess Peach.
"Oh poo!" she said, unsettled by her new voice.
