A/N: The title but with adjustments to the RWBY and HP universes. Also I'm feeling particularly surprisy right now, so... (drumrole) SURPRISE!
"Yang?..."
"Yeah lil' sis?"
"WHAT THE HELL ARE YOU WEARING?!"
"Oh this? I just thought I'd give you a surprise!"
Yang told Ruby, smirking at the younger girl's shock.
Ruby's shock, though, was not undeserved. Yang was wearing a...let's say inviting...open...and revealing...canary yellow bathing suit.
"Goes with my hair, doesn't it?"
Ruby covered her eyes and turned around, saying,
"Yang, change back into your normal clothes right now."
"Awww, I kinda like it. But anything for my little sister!"
Replied Yang, giving Ruby a wedgie.
"Sruff-cruo-ruf-scrofg-leme-go Yang!"
The black-haired weapon-enthusiast fought against her stronger big sister, but only got away when Yang let go. (100% her choice)
"Jus' showin' ma sis I love 'er!"
The blonde said, smirking.
Ding dong! The doorbell rang through the hallway.
"I'll get it!"
Ruby yelled, using her semblance to shoot down the hallway, away from Yang.
She quickly nudged her scythe, Cresent Rose, out of sight before opening the door to reveal a postman in an orange high-vis jacket.
"Uhh, here."
He said, stuffing two thick parchment letters into her hands.
"Err...thanks? I guess..."
Ruby replied as the man practically ran back to his van and drove off.
She checked the names, and saw that on one her name had been written on with green ink, and the other one had Yang's name in the same ink. Huh. Ruby thought. Then she called to her sister,
"Yang, when you're ready we've got a letter each in some kind of old paper and it's been written on with green ink!"
She took the letters into the kitchen and sat down at the table.
A few minutes later Yang walked in and Ruby handed the older girl the second letter, then began to open her own one...
