These jeans are so very tight. I've definitely been packing on the pounds. It's not enough, it's never enough. I need to be fatter now! Lucky me, I found a way to do so. A magic potion that will make it so when someone dumps their cum in me my body will explode with FAT! Every inch of me expanding outward at an alarming rate till I'm hundreds of pounds heavier. Will you donate your hot cum to your Step-Mommy's cause? This pussy isn't gonna fuck itself.
