A spanking and some improvements

You pull the paddle back, then slam it into Ms. Balls as as hard as you can. Her slightly plump ass quivers with the impact. The principal grits her teeth and grunts in pain, obviously not enjoying it much.

You reach inside her head and look at her memories of high school. She was a sweet girl who always did what she was told. That's useless. You make some changes, giving her memories of having a huge crush on her principal and regularly getting into trouble to get into his office. You implant memories of her masturbating while fantasizing about him spanking her.

Then you change her other memories until Ms. Balls thinks that she's fantisized about being spanked by every man she's ever found attractive. Finally you make her think that she instituted the principal spanking policy by telling people it would shame the students without hurting them, but really she just wanted a way to get boys to fulfill her fantasies.

Another swing of the paddle makes her ass ripple again, but this time she moans instead of grunting. You change her outfit to a red thong bikini, making everyone think that's normal for a principal to wear.

"Oh yes!" screams Ms. Balls as the paddle smacks her ass again. "You're such a bad boy! Punish yourself harder!"

"Well, if that's what you want, sure." You swing as hard as you can, turning her ass a new shade of red. You look over her 40ish body and decide it needs a little improvement. You firm her up and take off a little of the fat, mainly in the waist. With leaving her terrific 38DD chest, she now has a great hourglass figure. You whip the paddle into her ass again.

"OH GOD!" she screams with a delirious smile. "That's so... I can't take much more!"

"Well," you say, "I should probably mention that I messed up Jake Valden's face this morning."

"What?!" The principal stands up and readjusts her bikini top around her big breasts. "Well, spanking isn't going to be enough, then. What kind of punishment do you think would be appropriate, young man?"
