in this fantasy world of elves, orcs and other creatures, your mother and father divorced, you stayed with your father and he married a literal Cow girl. They gave birth to your two step sisters, Mia and Maya. They were very chubby and gluttonous but they were sweet.

years later you live a middle class life in a normal house, but your step sisters Mia and Maya are jobless and broke, they are also both morbidly obese. Out of the kindness of your heart and their irresistible charm and sweetness, you let them live in your basement. Maya is a shy girl who is self conscious about her weight, she usually wears her small outfit which has torn and outgrown her, which she still bellyaches about. Mia had more cow DNA from her mother than Maya, so she had cow ears and tiny horns on her head. She is more obese than Maya and eats rather shamelessly without care.

you return home and see Mia sitting in front of the fridge chugging milk and eating a lot of food

UUUUUURP oh hey… Maya is downstairs complaining about her weight again… she keeps saying it’s so hard to do anything… whatever that means…

Mia resumes downing gallon after gallon of milk
