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!

so the only way to top that is to **** in her hair supplies and stuff and make sure she catches you one day after she already used it cuz buddy chances are uve used that toothbrush after it has satisfied ur sister i think u should also catch her one day like oside the door and tell ur parents that would put her in counceling for a while

#43: What the hell is wrong with you!?!

I would have punched her in the ******* face.

dude i would punch her in the face... hahaha

Tell her to get a *****.

Total Epic fail Rofl didnt you even notice a change of taste rofl... you must of never gotten laid You got totaly pwnd Lmao

#6 is pure genius!! but seriously throw it away or burn it..something

Hopefully she had the decency to wash it when she was done. ...Even if she did, it's still gross... If I were to do it, (although I would NEVER - just saying IF) since I have one of those fancy ones with the removable brush tops so each family member can use it without getting a whole new one, I would either just get a whole new brush top for personal use OR I would use my dad's since he never uses it, he likes plain tooth brushes. And I would wash it thoroughly. Of course, I wouldn't actually do this, I'm just saying I would take some precautions if I were to do it.

: thats gross

Haha! Cheers to our sibling sisters! Oi!
