https://www.deviantart.com/vanboopLooking for an older comic by VanBOOP or VanDuo (goes by two names).
It was black and white, with a girl in a hoodie that agreed to test some sort of soda? Slime? Something like that. She began to gain weight rapidly, and it was very belly heavy. It was 3 parts, and I believe each part had a big chunk of story in the description.
The second part was her blowing up in her car looking embarrassed, and I think the third was her squashing the person who gave her the drink under her belly.
If anyone has any idea what I'm talking about please let me know!
