is it normal to masterbate to fantasies of my sister?

[bigtime21]

I like to think about her naked, and i often will take her dirty underwear and smell them as i masterbate. Im completely serious about this and i need to know what to do. Im sixteen and i have done it for awhile now, should i stop?should i tell her how i feel?help!

it depends this might be normal for a teen your age, do you get turned on by the thought that shes your sister or that shes just a female. that just it. and its mostly your raging hormones if you didnt finish pubarty then i guess its normal.
