Older sister!
You were a 17 year old girl named Mirai who was completely human in a family of cow hybrids, your mom and dad couldn’t figure out about how you didn’t have cow parts like they did. Your mom and dad didn’t cheat on each other so they couldn’t really figure out how this was possible as being the only human in the family but at least you were still loved.
You had an older sister name Sukimi, she was a cow hybrid, like the rest of her family, but she cared for you deeply. In her eyes, you were very precious and adorable. She couldn’t resist but hug you tightly against her body, but make sure to give you some air. She would always protect you as well.
Sometimes, people called you “Mini-Sukimi when your name is Mirai, but you were used to it anyways since you didn’t mind being called that name. Sukimi found it adorable though. But after a few years, your mom and dad died, but luckily your old sister was with you and you lived at her house until it was time for you to move.
NOW - Coming back from school: You came back from school at 3 PM, you were tired and you had homework to do, but you’d really didn’t wanna do it. And it was also on Friday, so why did the teacher had to ruin the fun?
Sukimi was in the farm, tossing haystacks over her shoulders and walking off to put them in the barn. Those haystacks were definitely heavy so you couldn’t pick those up if you wanted to. As Sukimi came out, she paused to see you walking back from school as she lit up happily.
“MIRAI!”
She happily yelled your name as she ran over with her massive chest jiggling, you looked up to see your sister run towards you as you stopped walking then she hugged you tightly.
