masturbation as a teen, I get pleasure too fast

I am a 13 year old girl , I have been masterbating for around a year now but I do it at night - my only time f privacy - any good tips on how to orgasm with homemade silent toys?

When I was 14 my mom caught me with a hairbrush handle in my p***y while I had my electric toothbrush on my clit. Talk about awkward! She never said a word after it happened, but I have seen (and even used her rabbit vibrator) so what could she say?
