This useful tool is commonly found in the range of 8 inches
in length. It’s function is enjoyed by members of both sexes.
It is usually found hung, dangling loosely and ready for
instant action. It boasts of a clump of little hairy things
at one end and a small hole at the other. When used, it is
inserted — almost always willingly, sometimes slowly, sometimes
quickly — into a warm, fleshy, moist opening where it is thrust
in and drawn out again and again many times in succession, often
quickly and accompanied by squirming bodily movements.

Anyone found listening will most surely recognize the rhythmic,
pulsing sound, resulting from the well lubricated movements.
When finally withdrawn, it leaves behind a juicy, frothy, sticky
white substance, some of which will need cleaning from the outer
surfaces of the opening and some from its long glistening shaft.
After everything is done and the flowing and cleansing liquids
have ceased emanating, it is returned to its freely hanging
state of rest, ready for yet another bit of action, hopefully
reaching its bristling climax twice or three times a day, but
often much less.

What am I??As you may have already guessed, the answer to the
riddle is none other than your very own…

toothbrush.
