Amber was about to drink the formula when her mother called her.
"Amber, I need help folding laundry!"
"Damn it!" Amber swore.
But she was a good daughter and always obeyed her mother. Reluctantly, she set the formula back on the table and trotted upstairs.
For about a minute the basement was silent and empty. Then a pair of cheerleading sneakers appeared on the stairs. They were followed by shapely legs, a narrow waist, a well-developed chest, and a beautiful face. This vision of loveliness was marred by the sneer on Charity's face.
"So my brainy sister thinks things are going to change around here, huh?" she muttered.
Charity was not a bright girl, but she had developed a predator's instinct when it came to protecting her popularity. Losing her spot at the top of the heap to her scrawny older sister was not what she had in mind. She picked up the bottle and smiled.
"She's right - things are going to change. Namely, me!"
Charity promptly chugged the bottle.
Not being very smart, it never occurred to her to remove her very expensive cheerleading outfit.
Her form immediately began to swell. Charity expected this. What she did not expect was the wave of arousal that washed through her.
Charity gasped.
"Wow, what a buzz!"
Her hands automatically moved to the breasts she was so proud of, which were now D-cups. She squeezed them with a force that would have hurt her mere moments ago, but now merely aroused her more. She could now feel her nipples, swelling with pleasure and potion, even through the thick cloth of her uniform. Immediately she began frigging them.
"Ooooh, yeah!"
She didn't notice her shoes bursting open, her hose shredding, her skirt snapping apart, or the fact that her arms were thicker than most people's thighs and her thighs were thicker than most people's waists. All she cared about was playing with her glorious boobs. Her top fell away, revealing an overloaded sports bra, tears already forming.
"Uhhhhhh, UHHHH!!"
Rip! Rip!
Her nipples popped right through the weakening bra, almost as long and thick as her thumbs. Realizing now how huge her tits were, she ripped off the abused bra with her right hand and used her left to lift her left basketball-sized mound to her mouth. Her tongue darted out and licked her three-inch nipple ... and she promptly had the biggest orgasm of her life.
"EEEYYYAAAAAA!!! OHHHHH, GOODDDDD!!!"
Panting, she collapsed to the floor, cracking the cement.
