She began to get extremely curious, she had never seen her mother wear underwear like this before. It was almost like she had planned on having fun before she visited, but she pushed that thought aside. She looked at them on the light, checked for stains or dirt, and even smelled them, it was like she never wore them at all. To satisfy her curiosity, she put the cups of the bra over her large bovine breasts, surprised at her mother’s size compared to her. It was a loose fit, but it it didn’t fall off completely when she put it on, so she assumed it would be ok. She then slid the panties on and once again found them to be loose, so loose she had to hold them up with her hands to keep them from falling off. Doing an awkward walk to the mirror in her bathroom, she got a chance to look at herself. Her mom might have been shorter than her, but she definitely had more tit and ass than she did. Not to mention, her MILF body made her softer, sag a little, and round. She liked the design and feel of them, but she could never fit in them, so she let the panties go, trying to undress and continue her day. But her body had other plans.
Her entire body started to vibrate as she had to swallow a few times, like she was getting stuffed with cotton that she couldn’t see. With every swallow, she felt mass hit her stomach and sit there, piling up on each other and blowing up, making her fill like a stuffed animal. Her stomach rounded out to a pretty sizable gut as she felt her face get loose. She saw a few of her hairs turn gray and then she felt her insides shift a little. Her areola grew massive and her pussy stretched and shifted to the point where she could shove her entire arm inside. She took a look at herself in the mirror, and she was surprised. It looked like she had aged 20 years, growing into a true MILF. New memories began to flood her mind, her mother now becoming her best friend, her apartment widening out and turning into a house, her deciding to sell her milk and now living comfortably in the country, her exes only liking her for being a cow and having massive tits, all sorts of new things that shaped her life and personality. She walked over to her bed and saw a picture of herself, and was surprised by how she looked. It was like she was a few seconds ago at a party with a cute boy half her size that couldn’t keep his hands off her, even for the picture. She giggled at the memory and thought about what to do next.
