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!

Baha. Buy the poor girl a vibrator.

Buy the poor girl a vibrator. It's not really that bad, I can hardly imagine her using the brush end, that would be a strange sensation.

wow man i need to have ur number. perhaps ur sis has msn? aim? anything?!

let some nasty ***** use it then wait for your sister to use it again. bingo bango she's got herpes revenge is served just like on south park or do number 57's sugestion

Tell that bitch to buy you another one.

Well, at least you found out instead of like continuing on without knowing your sister was using that thing for..her own purposes

oh absolutely disgusting! i am a sister of 3 guys and i would never do that myself that is so wrong on many levels.

Im going to be totally honest. It feels ****** sweet. But im not dirty like your sister. So im a winner.
