I wished that all the clothes she owned would fit her in the ways she found sexiest, however I changed her body. I toyed with the idea of having my preferences be dominant, but decided that it'd be more fun if she got turned on by how she looked. A second wish changed all her dress and work shoes into high heeled or platform versions. A third wish and she only owned sexy and trampy underwear. A forth and I returned her breasts, which had shrunk proportionately with her as I changed her height, to slightly larger than they'd originally been.
Miss Parks gasped as she felt her breasts bulge against the arm she was using to cover them.
"Why?" she asked me with hurt in her voice. She looked like she was about to cry.
"Well, most guys at school would notice if your rack shrunk, and this way most of your bras will fit okay." Of course they'd fit anyway, but she didn't need to know that.
"But," she paused and looked at me with a horrified expression. "I don't wear provocative clothes at school, why would they stare?"
"Duh, because you've got big tits, and it's so cold in the science room your nipples are almost always stiff during class." I made a quick wish and not only was it true that Miss Parks nipped-out at the slightest chill, but in her mind and the memories of everyone who knew her this had been true since she was a teenager.
I felt a wave of disorientation as my own memories shifted, remembered looking forward to seeing her nips on display after lunch every day. I frowned and made a wish that any future wishes would only affect my mind if I wanted them to, and that I'd always be aware of both the original memories and the new ones and could undo the changes at any time.
Miss Parks blushed furiously and stared at the floor. "I don't see why that should make any difference." Her blush was stretching down her neck onto the tops of her breasts. I wished I knew why she was so embarrassed by this, in her mind she'd had years to get used to it.
The knowledge came to me that Miss Parks secretly enjoyed men looking at her, and purposefully chose tight thin tops that were otherwise conservatively cut so attention would center on her nipples when it was chilly. She could easily have worn sweaters or warmer clothes to disguise her nipples, but chose not to. What I'd taken for shame was at least equal parts arousal; it was one thing for her to dress to be a sexual-fantasy for her students, it was another to be confronted with one of her students baldly stating how sexy she was. I decided to twist the knife a bit.
"Lady, you are the choicest piece of cheesecake on the teaching staff! There's not a guy in school who doesn't fantasize about getting an after-school anatomy lesson from you!"
I grinned as she stammered, trying to find some response that wouldn't admit how horny what I'd just said was making her. Her voice trailed off in a whine and I realized the hand she been using to cover her pussy from my sight was pressing tightly against her clit. Thin trickles of of vaginal lubrication were making their way down her thighs, and her other hand was not just covering her breast, but gripping it tightly. Her eyes were clenched closed, and she took short sobbing breaths. She was trembling and only holding that still by supreme force of will.
I took a few quick steps forward and whispered in her ear; "Go ahead, you're aching to do it anyway."
