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!

Your sister is a perv and gross.

your sister needs a boyfriend ;D

ew... that's horrid... I'm sorry love, at least you saw it before it was too late... (like AFTER using it XP )

OMG I'm so sorry for you, lol but that is kinda funny

mabey she was cleaning her ******?

oh my effing god.. that is vile!!!!!!!! I would have punched her in the head for that... and I would never punch anyone.. how many times has she done that without u knowing.. barf!!!

ok im totally lost WHY is this so bad dont guys eat chics out all the time and now its nasty only cuz shes using a toothbrush so shes ur sister just idk geet a new one

omg i just got shivers down my spine but think about it your lucky at least you came back in time to see that she had the tooth brush ,cuz think about it you would have put that in your mouth ....!!!!

the true question is why was your sister leaving the house with your toothbrush?
