Sally watched as her body packed on the pounds, her lower half starting growing fatter and causing her to rise in her seat. Her thighs were rubbing together and she now had cankles, her ass was the fattest she's ever seen. Her stomach was next, as it slowly creeped into her field of view it was gurgling and groaning. It finally stopped when it became a large gut, Sally liked the next part well at least until what happened afterwards. She watched her boobs grow again, this time getting bigger than her head, she felt joyful until they sagged a bit.
Sally felt an ache in her back, feet, and hips the biggest change was yet to come. Her hair turned grey but had a glossy look like she came from the salon, her body became wrinkly but, because of her fat most weren't noticeable, her face gained laugh lines and crows feet, her lips fattened up and were cake in ruby red lipstick. Sally saw her vision blur and then unblur as a pair of horn rimmed glasses adorned her face, her outfit changed as well, her jeans changed to loose sweatpants, her trendy shirt changed into a baby blue cardigan and a pearl necklace sat atop her matronly bosom.
Sally was taken aback, "I'm a fat busty grandma?!" she whipser yelled to herself catching the the bus drivers attention.
