Today, I heard my sister masturbating in her room. I took the dog around the block to get out of the house, and I came back to see her leaving her room. She had my electric toothbrush in her hand. FML

Fall

Dead leaves, the first cold of the season and an umbrella flipped inside out: fall, the season of grace.

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!

I think she was using the batteries from the toothbrush for her vibrator...

Fck, electric?

That's probably one of the "greatest" reasons to buy a new tooth brush if your parents ever ask you why you bought a new one.
