Missy owns a small farm just outside the city, handed down from her parents after they passed away. One night a meteorite lands in her corn field and while interested, the ground is muddy from the day's rains. Since it is late, she decides to check it out the next day.
Once out at the site, Missy notices that the meteorite can be hauled back to her barn where she can get a better look at it. Quickly, Missy starts noticing some changes as her breasts grow larger turning her into a futa.
