"I think that you need say something about, like what you want it to do?" Kevin ask.
"I want to be a man-eater."
The salve knew then what it had been consumed for.
"Arrggghhh!" Bethany screamed.
She fell to the floor twitching and convulsing as smoke poured off her lithe body. Kevin yelped in horror, thinking that she was going to burn up.
The salve went about changing who and what she was, a regular sized blonde into something far sexier. As smoke poured off her body and she moaned in pain her legs grew longer. It was her body going from 5' 2 up to 5'9. Her legs grew long and strong. Her upper calves bulged with muscles, Kevin thought her thighs to crack a walnut or a man. Her long legs twitched as Kevin saw the skin change from pasty white to an olive color like a Latino.
Her ass swelled making her cute little panties start to shrink in comparison. Butt cheeks as hard as rock started to swelled pushing aside the green fabric. Her panties looked like hot pants but they looked merely like a thong on her new ass. Her waist cracked as she grew wider in proportion to her new form. Her panties gave in and her nude ass was exposed to the world. The changes burned up the length of Bethany's body as her white stomach, with a bit of a paunch, became olive skinned and formed a six pack of abs.
Next was her breasts, as her chest expanded so did her tits. They swelled from handfuls through 32B to 34C then to 37DD breasts. Her bra stayed on but the mammary glands had pushed the fabric so far that the cups of her bra barely covered her nipples that had grown in size and pointed through the fabric, a stitch away from ripping the thing in half. Her new tits swelled around the cups of her bra. Barely covering the nipples, which had become bigger, darker and were erect.
"H-H-Help me!" Bethany moaned.
Kevin noticed her high pitched whine became something huskier and sultry. Her arms became longer, olive skinned and more muscular. Not like a body builder, or even her legs, but something far stronger than the twigs that she had had before as arms. Her neck grew longer and her obvious Adam's apple was erased for good as her round and shallow face became more defined. Her cheekbones grew higher, her eyes became hooded and her lips swelled thrice their old size. Her eyes burned as they went from pale blue to dark brown.
Her hair became jet black and grew down to her ass, as thick as the jungle in the Amazon river. Her finger nails clawed at her chest, her nails were longer than anything she had seen in her life and her bra was finally shredded. Her huge tits wobbled like mounded of jell-o in an earthquake as she slowly pulled herself up. Her long legs made her feel like a new born lamb, but slowly she got the better of her new body and walked over the the mirror.
"¡Madre de Dios!" she said automatically in Spanish.
"What the fuck?" Kevin asked.
"I know Spanish." Bethany mumbled in English
She looked at her nude form. Her ass was as taunt as the skin on a drum, her tits were twin peaks that would push into any bra or shirt she wore. Not an ounce of fat on her body, she was a lean, fit fucking machine. She would have to buy a new wardrobe, jeans, underwear, shirts, bikini and visit the adult shop. But she felt a hunger that wasn't for food or drink, it was for cock, for the meat of a man. She could smell the cum inflating the man's balls. She knew his name once, now he was just food, prey.
"You wanna fuck me little man?"
