Ways for it to happen? Girls only please! Thanks!?

Okay I'm a girl and I'm 12. I masturbate and I use an electric toothbrush (I've never put it in my mouth and never will!). Obviously, I live with my parents so I do it at night time. Are there other things to masturbate with to reach an ? (No vibrators, they are too loud and my parents would know something was up.) I'm not trying to be sick or funny. Please answer this seriously. Thanks!
