Jon had to fight Mikey's mind control. "He's my little brother, I can't do this. I have to resist no matter how hard.....hard...AH MY THOUGHTS!" He was practically screaming in his head. He was already sprawled over Mikey's crotch and went for the zipper when there was a knock on Mikey's door. The two instantly stopped and Jon regained his mentality for a brief moment. He stood up and tried his best to distance himself from Mikey. Mikey simply looked at the door in surprise. He saw their dad, Mark,coming in.
"I heard some noises and....MIKEY!" His dad shouted. "How many times do I have to tell you, you're too young to have sex with your toys!!"
"Dad! It's me Jon!" Jon pleaded. "Help me! He's taking advantage of me!!"
"See what you've done!" Mark said sternly. "You scared your monkey toy."
"I'm not a toy! I'm your son!!" Jon tried to convince him, but Mark just ignored him and sat next to Mikey.
"Look son..." He placed his hand on Mikey's shoulder. "I know you may have urges, but I want you to wait til you're 18 until you 'play' with your Jon Monkey in such a way. Can you promise that?"
"Sure dad!" Mikey said with a smile. He then aged himself to 18 and a matter of seconds. Even his clothes altered to match. "See, now I'm ready!"
"Haha, I suppose you are!" Mark said oblivious to everything that was happening. "Just don't make too much noise!"
"MIKEY!" Jon screamed. "You're turning this family into a bunch of freaks!!"
"Hey that's no way ....whoa, my voice." Mikey said. "That's no way to talk to me. You're just mad because your fantasies aren't coming true!"
"I would still be mad even if they did!" Jon replied.
"Oh yeah?" Mikey retorted. "Let's see about that."
Mark was about to leave the room when he turned around and looked at Jon. Mark was frozen in place as Mikey invaded Jon's mind to find his deepest, most carnal fantasy. He seemed to have found it rather quickly as Mark began to change. Much of his height diminished and his features were growing softer. His hair was growing from a thinning brown to a long platinum blonde. Soon, two orbs sprouted on Mark's chest becoming breasts comparable to Jon's. His waist tightened and his clothes were changing as well. His brown slacks disintegrated revealing long beautiful legs clad in white stockings and black mary jane heels. The belt he had on became a green plaid microskirt and his underwear a pair of pink panties. His dress shirt tightened and rearranged itself to show a large amount of cleavage. To add some finer details, Mark now had pigtails, painted nails, and even make up on. The only thing left of his old self was his face, but everything else belonged to a naughty teenage school girl.
"Kinda boring if you ask me, but hey, what do I know?" Mikey chuckled.
The buxom schoolgirl formally their father put her hands on her hips and winked at Jon, before walking out of the room. Jon was stunned as he could hear her heels clicking in the hallway....
