Fingers?...no...hands

I have been doing this for a while since I was very little. You can do it in a chair. You sit in a chair and cross your legs(left leg over right) and then take your left hand and put it up against your pussy(clothes or naked) and then you start riding your hand. You can do it in bed laying on your left side and using your left hand and doing the same thing. It takes about 5 minutes to cum. You will love it.
