【Sister in law Who Let Me Use Her Hole】

These two sisters are Sister in law Who Let Me Use Her Holecooler than any of us will ever be.

Audrey and Kate are average kids living in Japan — they vlog about learning calligraphy, they play hide and seek, and oh, they perform the most metal covers for YouTube.

Their cover of Slayer's "Raining Blood" even landed on Reddit's front page this week.

The two sisters learned to play guitar and bass from Rocksmith, a video game that teaches players how to play real instruments. Their YouTube channel is full of videos of their impressive covers, including My Chemical Romance's "Welcome to the Black Parade" and Queen's "Bohemian Rhapsody."

They've even covered System of A Down's "BYOB" and it's pure joy.

While Audrey usually concentrates on shredding, her little sister provides hilarious backup vocals, like in their cover of Trivium's "In Waves."

Audrey and Kate have a fanbase of all ages, and people love their authenticity.

"THIS is what YouTube should be," u/Saiing commented on the viral Reddit post. "Entertaining videos uploaded by two regular girls having fun. I wish more YouTube was this instead of all the focus being on influencers, corporations, and factions of idiots following individuals who are more brands these days than real people."

They have a point: It's so much fun watching Audrey and Kate perform because they'rehaving so much fun. Just watch Kate swinging her legs to Primus!
