go buy a new toothbrush with replaceable heads. brush your teeth until the original one is used beyond reason. then put a new one on it. then MAYBE your moth will be sanitary. god it's like you've been going down on your sister twice a day. ewww. incest via toothbrush.

If you had a normal regular toothbrush you wouldn't have this problem. Switch tooth brushes and buy the girl a vibrator. Problem solved. Or - what the guy above me said. Brilliant!

what if she was doing that before for a long time and while you were using it and didnt know until now.. that would be sad ..

what if she was doing that with your toothbrush all along and youd brush your teeth every single time after and didnt know until now.. that would be sad .. ew..

use it. it'll cure cavities.

you poor unfortunate soul
