I don't know how I feel about seeing my mom on multiple fetish websites.
Are you serious?
She masturbates with a horse-hair brush, a double-ended dildo and a mushroom.
That must've been an eyeful. What were you doing perusing multiple fetish websites, anyway? Not that there's anything wrong with it, if that's you thing.
I was looking for a roommate to replace her.
Everyone has some type of fantasy or fetish, regardless of how odd it may seem. You should try to respect your mom's privacy so that you won't have to see anything disturbing.
