No, the opposite.

"On the other hand..."

The professor pulled out her own phone and looked at herself. She started making the same kind of changes to her own face that she'd made to yours, except more subtle. She checked her reflection after every change and made lots of small adjustments to be sure. Her eyelashes became naturally longer, her hair went from dark brown to pure, silky black. Her cheekbones rose slightly. At the end, she still looked like herself, well, the 19 years old version of herself, but she was much hotter.

Then she went to work on her body. She'd already given herself H-cup breasts and some extra height, but she clearly wanted more. She shrunk her waist and widened her hips, not a ton, but enough to give her a great hourglass shape. Her butt pushed out a bit, and after she took off her jacket she upped her muscle mass. It wasn't anywhere near the body builder proportions she'd given you, just enough to look tone while still being feminine.

She looked fucking hot.

Finally satisfied after a half an hour of messing with both your bodies, she put both phones down on her desk. "So what do you think?"

Your cock was hard as hell looking at this sex goddess. Of course you said, "You look incredible!"

Her perfect lips formed a perfect smile. She put her hands under her huge tits and pushed them up. "I can see your pants have gotten even tighter. Have I succeeded in making myself into the perfect sex object that you were trying to achieve with the girls in your class?"

"Yes! God, you're so hot, ma'am!"

She licked her lips. "Hmmm. I've done a pretty good job of making you into my fantasy of male perfection, too. I don't know, maybe the app is messing with my head, but what if we tested these new bodies out? What do you think, do you want to fuck your teacher?"

You nodded eagerly and said, "Yes! I do!"

"Well, I don't know. You might just be saying that because I made it hard for you to object to anything. Tell me the truth, Mr. Doe, and it is okay to say "no". Do you enthusiastically want to do this?"
