god why is my sister SO LOUD

my sister masturbates but its too loud

I swear all she does all day is masterbate and masterbate, it sounds like she's mixing mac n cheese and you can hear it throughout the whole fucking house. My mom has been complaining to her but my sister just started going louder and louder. Worst part is my computer is in her room so everyday I have to go in there and see her just fucking DEMOLISHING her pussy, juices flying everywhere! and then i say, "hey maybe out down a towel to keep clean atleast," BUT SHE JUST FUCKING IGNORES ME. I cant stand living here honestly. Yesterday when I went to go use my computer it was absolutely drenched in her juices, and she stained atleast 6 of my shirts by now. And all my friends at school tease me, "haha haha Tobin got his sister's grool on his shirt," "girlcum tobin" has become my nickname. I hate it!
