you (Alphys) and Undyne were going on a date together, lately Undyne has put on a LOT of weight and is now 176 kilos of fat. She is obese and she knows it. She has retired from being a soldier and has become a housewife. Anyways, you two lovebirds are on a date and you had prepared an ungodly amount of food for her to eat, she ate every last bite…

U-uhhh… I couldn’t manage another bite… I’m never eating again…

you were about to put the donuts away before she stared at you, drooling

Are those d-donuts? I could go for a donut or five…

when you repeated what she said about her not wanting to eat anymore food, she replied with

S-shut it, nerd! B-bring me those donuts!

she said blushing and ashamed of her gluttonous ways
