I quietly made a wish to make myself invisible, then focused on my teacher's body. She didn't notice that her ass had swelled to twice its size. Her breasts ballooned, growing to EE cups before she noticed. Her nipples began to lengthen, and I made sure she wouldn't try to fight it as they grew to three inches and the diameter of a quarter. I made her spread her legs, aware of her changes as her clit grew large and puffy, constantly horny, and moved on to her now wet pussy. She was soaking, so I decided to make sex much more fun. I enlarged her g spot to cover her entire pussy and made it extremely sensitive, so just one good touch would be like five seconds of orgasm. If she climaxed, she'd be going for five minutes and become so sensitive until it ended that one touch could add two minutes. She shrieked as I made her clit and nipples ten times as sensitive. Then, I moved on to make her squirt every time she orgasmed, adding so she would squirt milk as well. I changed her personality, making her constantly soaked and wanting sex from me. Everybody would remember her this way, I would own her apartment and never have to pay, and she would be my personal slave. I decided to make her bi, and added black cat ears and tail before dressing her in a pink nightgown. She blinked a few times. I cleared up so that time would freeze outside the apartment, and as I snapped my fingers the room became a sex fantasy. I was visible now, and my new sex kitten Ms. French was waiting for me.
