Lindsey, a blonde girl in the front row, volunteered to clean up. Apparently, Jen realized, the infected water mutated anyone who came into contact with it, rather than just those who drank it.
Jen watched in resignation as Lindsey bent down to clean up the spill with a towel, sticking her ass into the air. While this wouldn't have been a problem if she had kept the jeans she was wearing, the mutation affected clothes too and Lindsey's pants morphed into a skirt, and her panties disappeared, leaving her asshole and pussy on full display. Her breasts swelled to K-cups, dripping milk through her sweater. Her belly also swelled up, pregnant, and Jen could see one of the babies crowning in Lindsey's vagina. Lindsey grunted and moaned in pleasure as she tried to continue cleaning up while giving birth, until finally the infant was fully out and the teacher picked it up with one of her handheads and brought it to a bin next to the door labeled "Lindsey's babies". She set the infant down in the container, and Jen could hear a few more crying inside. She looked back at Lindsey herself to see her belly swelling with another baby already.
One of the teacher's breasts spoke up, asking for a volunteer to take this load of babies to the office.
