Her clothes start to tighten and she is starting to put on some weight. Her stomach bursts out of her shirt exposing her large belly. Her hips and thighs widen and then rip her pants. She stands up embarrassed by standing there naked, then her ass starts to jiggle as it gains 50 pounds, her face changes too as her cheeks get rounder and chubby and she has a large double chin. Her perfect thin bony changed like that in an instant to a larger new one. She looks like 235 pounds now but she's still growing. Her belly hangs to the ground as she gains two more rolls, her arms balloon out and fatten up her hips go even wider and her thighs are thicker than your chest. She runs to the car embarrassed and crying you quickly hurry after her. She try's to squeeze into the passenger seat and she finally does. You get into the driver seat and drive her home.
"I'm a big fat ugly pig!" She yells.
You try to calm her down but to no avail she won't listen. You tell her she looks great but she doesn't listen. You finally get her to her house and she waddles as fast as she can to her bedroom and steps on the scale.
"324 pounds!" She yells in horror "how am I gonna burn this disgusting fat off!"
"You don't have to you say..."
"What do you mean she says?"
(Secretly you had a magic potion that makes her like her fat self) you pull out the philtre for you pocket and throw it on her.
"Startled she yells what did you do... To my body?"
"It looks good doesn't?"
"Yea" she says admiring her thunder thighs and large belly.
