They waited for a few more minutes. Nothing happened.
"See? I told you it wouldn't work." The 25 year old Tiffany said
"Maybe you're right. Perhaps we should try someone else." Margaret said as she turned to the doctor.
Tiffany gasped as the formula suddenly started to work.
"Oh! Something is happening!" Tiffany exclaimed
"What's wrong?" Dr Abrams asked her
"I feel... odd." Tiffany said as the formula started to affect her body.
She gripped her stomach as she began to grow taller. Her skin became more toned. Her breasts grew larger.
"My clothes! They're getting tight!" She wailed with teary eyes.
The fabric of her blouse began to tear apart as her breasts continued to grow. Her skirt ripped open as well, revealing her growing legs.
"It's working!" Justin exclaimed.
"Yes, it is." Abrams agreed.
The two women watched as Tiffany continued to grow. Her body continued to expand, becoming bigger and stronger.
"Oh SHIT!" Tiffany cried out as her breasts grew even larger pulling her bra tight against her back.
"You're doing great, Tiffany. Just keep going." Abrams reassured her.
"I can't stop it!" She shouted as her body continued to grow, her feet tearing apart her size 7 heels.
"Don't worry, it'll be over soon." Margaret assured her.
"I feel so... full." She moaned as her bra finally gave way to her breasts.
"Just a little bit more." Abrams reassured as she watched Tiffany.
"Ah! Ahhhh!" Tiffany cried out as her breasts finally stopped growing.
"You did it, Tiffany! You're finished!" Abrams exclaimed.
"Oh, thank goodness." Tiffany sighed in relief.
"I can't believe it. I'm huge!" She said in amazement as the growth stopped. "Yes, you are." Abrams agreed.
She looked down at herself. Her B cup breasts were huge, each one the size of a grapefruit. Her shirt was completely destroyed, leaving her naked from the waist up.
"I feel so... powerful." Tiffany said as she flexed her muscles.
"That's the serum for you." Justin said proudly.
"I'm not sure if I like this." Tiffany said as she looked down at herself taking in her new stature.
"Don't worry, you'll get used to it." Margaret assured her.
"I think I need some new clothes." Tiffany timidly said as she looked down at her shredded skirt.
"I think that can be arranged." Abrams said as she walked over to a closet and opened it, revealing several large lab coats.
