For the third class of the day, Mrs. Watson had to apply a test, so she thought it best not to disturb her students with the remaining 'aphrodisiac' pills from Jen and Claire. She also knew that she could not invade classes in class with other teachers, but she ended up having an idea that she thought was very interesting. She then handed the exams to her students and told them not to cheat, so she took off all her clothes saying that this was so they wouldn't know where she was in the room, but that they could be sure she would be there and would see if someone cheats.
With the first step of her plan, the teacher left the room knowing that her students believed she was still inside the classroom. She went to the cafeteria and went into the kitchen, where lunch was being prepared.
Taking advantage of her invisibility, Mrs. Watson walked around the kitchen placing the pills inside the pans ensuring that she had placed pills in all of them. She didn't see lunch time and just imagining how things were going to go, her invisible horse cock got painfully hard. She couldn't help it and started jerking off right there, all without noticing what happened to Kimberly, a former school student who now worked in the cafeteria, when she tasted some of the food to see if it was okay.
First a bulge appeared in her pants that grew without stopping, it didn't take long for the pants to no longer support the pressure and tear, revealing a trio of cocks, each with its own ballsack, before the torn fabric completely disappeared from existence. Kimberly's new cocks have grown to become 7-foot meat towers, each as thick as a tree trunk. Her balls also grew until each of the 6 was at least twice the size of a yoga ball.
Mrs. Watson watched the newly transfirmed woman while jerking off, believing that she always had those monsters between her legs, believing that the 'aphrodisiacs' had made her hard. Seeing this and how Kimberly walked relatively easily even with the huge heavy balls between her legs, and the hard cocks of which the tips almost touched the ceiling. That was too much and Mrs Watson came, aiming for the open pots and making her invisible cum mix with the food that was being prepared.
When her orgasm ended, the teacher left the kitchen and returned to the classroom looking forward to lunch.
Lunch time. Both of their bodies eat from the cafeteria food.
