"Let's send in a message and say that we would like to take the rest of the day off to get used to our new bodies!" suggested Emily. "Yes", said Julie. Beth nodded and crawled over to the computer, where a metal bar rose which she could lean on. Her breasts gently wobbled as she moved, and milk began to drip from her nipples. Then the computer turned on and she quickly navigated to the email system, where she explained what had happened in the class and asked for the rest of the day off.
The reply came almost immediately, saying that yes, they could as they had with Dr. Julia when she had first drunk the serum.
Julie nodded and a video call started with Dr. Julia. She told them that they would have two days to get used to their bodies and such, and then they would have private classes with her, and she would be their only teacher. The girls nodded and Dr. Julia told them that the serum prevented pregnancy, imputting a special gene that would basically switch off their birth systems until they were of age, in this case, 23. The reason for this was because if they got pregnant at school, it would be hard to attend classes. With them already in a state of crawling, it would be best if they couldn't get pregnant until they were older and able to hander the weight of both. Then the video winked off.
So the girls dispersed and went off to get used to their new selves or explore their dorm.
