Erika was an only child but her mother had made a pregnant belly cast when she was 9 months pregnant with Erika. Going to a Halloween party nude was wrong but Erika's mom used the cast and painted it with a Halloween pumpkin. The cast had a strap on it. Seized with panic she grabbed it and threw it at Meg.
"Put this on!" she shouted.
"Are you sure?!" Meg gasped.
Feeling like she was going to die she started to put the costume on. Her salve soaked body started to react with the plaster cast, even through her school uniform, the painted pumpkin vanished as the belly cast took on a fleshy tone the breasts became so life like that they started to leak milk.
As Meg jumped around the life like cast bounced and wobbled as if she were really pregnant. The cast then deflated soaking through her uniform into her teen body with a noise like water being sucked through a drain until it vanished leaving Meg looking completely normal in a navy blue pleat skirt, white shirt, blue tie and flats with stockings.
"What the fuck?!" stammered Meg.
Deep inside Meg the Salve and the chosen form were transforming the teen. Her coney breasts started fill with milk as her body was flooded with pregnancy hormones. The nipples grew pointed, darkened and wet spots appear on her buttoned shirt and through her A cup bra as milk soaked through.
Erika watched as newly created baby swelled inside Meg's womb. Her stomach was like a fleshy water balloon the taunt skin lifted her shirt out of the waistband of her pleated skirt. The teen tried to pull the white fabric down to cover her belly but it kept growing exposing a popped out belly button.
Meg let out a low groan as the sound of creaking fabric as her cotton shirt and buttons started to snap under the pressure of her baby. Bits of her stomach were shown as one by one the buttons made audible pinging sounds as they bounced off the mirror. In back of her shirt small rips started to appear as her belly ripped through any barrier.
"Quick! Undo the buttons..." shouted Erika.
Meg fumbled with them but her body was too fast the remains of her shirt were ripped in half exposing her protruding belly in which her belly was alive with movement like to cats in a bag fighting.
The teen stumbled back towards Erika's bed where she collapsed more belly than girl. Her small breasts grew until the cups of her bra, weakened by being soaked in milk, snapped but her skirt held onto her chest area. Meg fumbled for the buttons and ripped open her shirt exposing C cup breasts that engorged with milk rested on her belly. Her school tie lay in between her breasts.
Meg spent the next hour passed out on Erika's bed before she was able to muster the strength to stand up. Her legs wobbled as her young body hadn't had time to grow with her pregnancy.
