Her rich friend, Portia.

You look through the peephole and see Millie's friend Portia. If Millie was bad, Portia was worse. Thanks to her rich father she'd had everything handed to her on a silver platter, including a boob job and plastic surgery that had taken her from very attractive to 'uncanny valley'. All her new features were attractive individually but not so much when taken as a package (not that anyone would tell her that). The girl had probably never heard the word "No" in her life...

... which gives you an idea. You once read a story about a girl who was cursed to always say 'Yes' and to do whatever anyone asked of her and, while making Portia do the same thing appeals you decide to alter the idea a little. You wave your hand and make it so that Portia will answer any Yes/No type question put to her with a "Yes" and that when she does so her memories, beliefs and personality will change to make her answer true.

You open the door...

"Hey, loser" says Portia, her perfect mouth twisting into a sneer “Aren’t you supposed to be at work making money for Millie? You know she’ll kick you out if you don’t pay your way.”

“Wow Portia” you say “Don’t you ever get tired of being a bitch?”

Portia gasps at the tone of your words and the impudence of you saying them and is about to spit out a stream of invectives …

… “Yes” she says and her entire manner changes. Gone is her usual bitchy demeanour and air of superiority, replaced with a look of emotional tiredness, her perfect brows lowering and her perfect lips turning down. “I’ve just been bitchy so long I’m not sure how else to act.”

“Would you like me to help?” you ask

“Yes” she says, “If you think you can.”

“I can try.” you say, “Follow me”.

She follows you inside and then stops when she sees 'Millie The Maid'.

"Ello Portia" says Millie in her French accent.

"Wha...?" says Portia her perfect eyebrows shooting up.

"You remember how Millie likes dressing up like a French maid and cleaning the house, don't you?" you ask.

"Yes ... that's right I'd forgotten." says Portia.

"O.k. Millie. You keep cleaning up, I'm going to help Portia with something" You say (making sure Millie is more than happy for you to do whatever you want to with her friends).

You take Portia into you bedroom and then sit down on the bed. Portia sits down beside you.

"So" you say "You first started being a bitch at school, is that right?"

"Yes"

"And you went to an all girls private school, is that right?"

"Yes" says Portia and you can almost see her memories changing to fit this narrative.

"And you've brought along the uniform you wore and put it on now?" You say and change Portia's clothing to that of a private school girl complete with plaid pleated skirt, black Mary Janes, white knee high socks, white cotton underpants and a white cotton bra and shirt which you make uncomfortably tight to give the impression that her boob-job has made her breasts too large for them

"Yes" she says after the shock of having her clothing instantly changed for her wears off, and her shock goes away as she remembers changing into the uniform herself.

"O.k. so, again, you realise that being a bitch is bad?"

"Yes"

"So do you think you should be punished for all the bitchy things you've done?"

"Yes" she says and she looks guilty.

"Then stand up and pull your underpants down to you ankles." you say and Portia does as she is told allowing you a quick glimpse of her hairless slit which looks too perfect to be real. "Now lie down across my legs" you say, and she does so placing her breasts on the left side of you and her legs to the right.

You flip up her skirt to reveal her beautiful butt, almost as nice as Millie's and the only part of Portia you are almost sure is unaltered. "Now" you say "I'm going to spank you, and as I do we are going to get to the root of your problem."

You raise your hand and bring it down on her right cheek causing her to gasp from the shock and sudden pain.
"Now" you say "You remember your days at school don't you?" (Left cheek) *Slap*

"Ah! Yes."

(Right cheek) *Slap* "You remember the girls?"

"Yes"

*Slap* "You remember how attractive you found them?"

"Y-Yes"

*Slap* "How you'd think about them as you touched yourself? Think about their naked bodies? Think about touching them?"

"YES"

*Slap* "Your thinking about it now, aren't you? It's really turning you on isn't it?"

"Oh! Yes."

*Slap* "But you were too afraid to act on your desires. Too afraid of rejection"

"Yes"

*Slap* "So you drove those you were attracted to away by being a bitch, is that right?"

"Yes"

*Slap* "And you are doing the same with me. You're being a bitch to me because you're so attracted to me."

"Oh! Yes."

"And being here in my bedroom with me with your panties around your ankles and your ass bared to me is making you more turned on that you've ever been isn't it?"

"YES!" cries Portia and you can feel her perfect pussy start to weep with arousal.
