I decided to experiment with her and find out her reaction to a specific transformation. "I wish Mrs. French would get extremely horny and start masturbating right now. While she masturbates, a dick and balls will start growing, slowly, in front of her vagina, and will only stop growing when she complains that it is getting too big." It was the wish I made.
The urge took effect and Mrs. French began to masturbate, with one hand she inserted two fingers into her pussy and with the other she rubbed her clit. Not satisfied with just two fingers in pussy, she put one more saying "What's happening to me? I've never been so horny before." Then she felt something strange about her vagina. She took her hands from there to see what it was. She looked a little confused as to what that was, but I was pretty sure it was a very small cock, only 1 inch erect and bead-sized balls.
Curious, but still unsure of what it was, Mrs. French decided to touch it, which sent a wave of unfamiliar pleasure to her. In the state of arousal she was in, it made her resume her masturbation, still with three fingers in her pussy and the other hand using two fingers to stroke her new mini dick.
As she masturbated I could see her cock growing, reaching 2 inches and the balls growing to match. When her dick reached 3 inches she came, she lay down during orgasm and I watched as she ejaculated like a man for the first time.
Recovering from orgasm, Mrs. French decided to look more calmly at her new cock, which was still erect and already 5 inches. She touched him and tried to look from every possible angle, and when her still growing cock hit 7 inches she said "How is it possible for someone to grow a dick suddenly? and it doesn't stop growing."
As soon as her cock reached 10 inches in length, she felt the need to masturbate again. With the current size of her new appendage, she needed to use both hands, and it was changing strategy while her dick kept growing. At 12 inches she started to tit-fuck herself. With 14 inches she put the tip in her mouth, this allowed her to free one of her hands and put a few fingers in her wet pussy, now hidden behind her now huge balls. When she finally came, her monster was already 16 inches long. This orgasm was more intense than the last and Mrs. French ended up sleeping soon after.
I stood there watching Mrs. French sleeping in her bed, her dick was still erect and still growing. As she didn't wake up and her dick was already too big I asked for the ring "I wish Mrs. French's cock would stop growing." But this time my wish didn't come true and there came a voice in my head that said "No wish can be used to interrupt another wish in progress."
With that I saw that I had no choice and had to reveal my presence in her room and wake her up. As soon as I woke her up, she asked what I was doing at her house, So I lied that I wanted to deliver my late schoolwork, but since she was already out of school I had taken her address and gone there.
"But Mrs. French, since when do you have it?" I pretended I didn't know what was going on there and asked pointing to her dick.
Just then she remembered the member growing between her legs and said "Oh no, it's growing too much." As she said this, her cock pulsed and visibly stopped growing, with a final size of 2 feet long, with the tip at eye level. "Oh my God!! I thought it was just a dream." she said
