In light of what happened, Jen decided not to go to school. She and Mary helped her mother, who was still learning to walk on her new legs, to the bathroom, where her mother and the maid took off their dirty clothes and were going to take an emergency shower. Then Jen went downstairs, put the cum-stained clothes to wash, then went to clean up what was left on the floor before.
While cleaning, Jen only realized that an hour had passed when she spat out another pill. She had to act quickly and decided that now was the time to sacrifice Mary. Looking for the maid, she discovered that she was still in the shower with her mother and, from the sound coming from inside, Mary was dealing with yet another erection from her mother.
With the bathroom door locked and no option, time ran out and Jen's body moved on its own, forcing herself to swallow the pill. After regaining control of her body, she tried to vomit the pill before it took effect, but it was too late and she could feel her body changing. A strong pressure occurred inside her and her panties were stretched as they filled quickly, Jen then lifted her skirt to see what was growing and came across an extra head growing on it, attached directly to her crotch. Her vagina sealed completely and two masses grew in place, leaving Jen with a pair of breasts twice the size of the originals hanging between her legs.
Jen felt strange being able to see from two different points of view at the same time, momentarily with each face facing the other, but her transformation was not yet complete. With her head down she saw her original head become a three foot long dick and her original breasts grew and merged into a huge ballsack.
While transforming and contemplating her new body, Jen forgot about her mother and Mary and didn't realize that they had finished their bath, only realizing that the two found her transformed when she heard the sound of her mother's hooves against the floor.
Mutant mother and daughter stared at each other while Mary looked from one to the other in amazement.
