Jen's body ran through the streets, passing block after block, she thought she was safe until a woman walked out in front of her. Jen didn't get a chance to see the girl before she hit her, the woman's body exploded into a mist, which followed Jen as she continued running. The mist absorbed into her and she felt her body shifting again, her breasts expanded larger and larger, until they were the size of basketballs.
Jen's ass expanded, rounding out to make her body more feminine, and nearly an hourglass, while her skin tone darkened slightly, to a natural tan. Jen's hair grew out, and braided itself behind her, turning a dark auburn. She saw her viewpoint raise by several inches, making her at least seven feet tall. Jen looked down, seeing her new enlarged bust caused her cock to go hard, it's stiffness foreign to her as it wobbled side to side in front of her, her body was now completely naked, having busted through her bikini while growing. Jen continued to run, flustered by her arousal and the new sensations of her larger breasts and ass jiggling with every step.
As if to sense her hunger, her body involuntarily reached down and gripped her new cock, starting to stroke it.
"No no no, You don't need to do that I'll be fine." Jen said slightly embarrassed by her now different hands, but they didn't stop, and she soon found herself climaxing cumming as she ran. Jen moaned loudly and then sighed.
"Uh... Thanks... I needed that." She said, and to her surprise her right hand reach out in front of her and gave her a thumbs up. Jen didn't realize it yet but the curse was going to provide as comfortable of a run as possible, even if it was going to change her completely.
