Her teacher

John and Hayley drove around until they found Taylor Swift out on a jog.

"How about her as your teacher?" John asked.

"Yes, please, Daddy!"

John froze the blonde singer with the wand and put her in the car. As they drove around, John realized he wanted more daughters. He had an outgoing slut in Kylie, and a shy nerd in Hayley, so why not add two more daughters to the mix? He wanted to do a bit of personality mixing, so he would get a shy daughter with a secret slutty side, and a nerd who was also an avid party girl, so he drove around until he found two women to fill those roles.
