As soon as the transformations finished, each clone coughed up another pill from the other head. Even the Mom with a foot-head! But not the clone that had been Jen's father since she did not have two heads when the curse was passed on. They four moms each swallowed their second round of pills and the transformations began anew.
The mom that had transformed into a humantaur was also a mom that had three penises. The trio of cocks retracted into her body. Only to the reappear from her tailbone like a bizarre, meaty horsetail.
The mom with four heads grew two more legs and breasts. Then, she split down the middle. Each "half" had two heads, two legs, two boobs, and one (1) vagina. However, the half-moms only had six arms to share between them. One had three right arms. While the other had the remaining three left arms.
The mom with six cocks could only stare as her six arms retracted into her body. Then, she discovered her half-dozen dicks sliding up her body. The migrating meat split into two groups and moved onto her sides. Then, they took up positions where her arms had been. Her six penises grew in length and size as muscles appeared inside them. She could flex her replacement arms like meaty tentacles. Finally, from her crotch, a single arm grew in her cocks' place. So at least she could have finer degree of control.
Last was the mom with the many feet. Her original legs fused together and rapidly started to shrink in size. She fell to the floor. But she caught herself with her many legs. The writhing, mutating flesh coalesced onto the form of a single left with a mouth on its sole. It mirrored the foot-head that had been this mothers heads. To further sell the illusion, her torso shorted and morphed a second part of shoulders where her new foot-head now sat. It was nearly impossible to tell which end was which. The only tell was the way her six feet where facing.
Things kept getting weirder.
