It wasn't just a something but three somethings.
Jen had run over three, equally tall busty women. Jen's huge body stood up and took her head off the three women took their heads off at the same time. Her body reached down with her head and placed it upon the neck of the first busty woman. Her curves now a full hourglass she looked down and felt somewhat happy, but then the other two girls heads were taken. Jen began to scream in voice not her own as the other two bodies approached her but then suddenly both of them tripped and fell. They rolled over as Jen's first body stood stock still, her other bodies stood up, but instead of turning aroud they backed into her, their necks connecting at once, her three bodies now facing in three different directions.
Jen screamed even louder in three voices as her new bodies moved in their new positions toward the sea, she felt her backs pressed together and her busts facing in different directions. This alien feeling of having six feet in three different directions terrified her. The girls on the other hand walked with their new massive body towards the mountains. Jen continued to scream as her three bodies reached the surf and were spalshed. Gaining control she stumbled toward the beach and finally collapsed fighting her new form in all directions and sobbing at what she had become.
