I'm about 8 inches long.
My functioning is enjoyed by members of both sexes.
I'm usually found hung, dangling loosely, ready for instant action.
I boast a clump of little hairy things at one end and small hole at the other.
In use, I'm inserted, almost always willingly, sometimes slowly, sometimes quickly, into a warm, fleshy, moist opening.
There I'm thrust in and drawn out again and again many times in succession, often quickly and accompanied by squirming bodily movements.
Anyone found listening in will most surely recognize the rhythmic, pulsing sound, resulting from the well lubricated movements.
When finally withdrawn, I leave behind a juicy, frothy, sticky white substance, some of which will need cleaning from the outer surfaces of the opening and some from my long glistening shaft.
After everything is done and the flowing and cleansing liquids have ceased emanating, I return to my freely hanging state of rest, ready for yet another bit of action.
Hopefully, I will reach my bristling climax twice or three times a day, but often it is much less.
WHO AM I?
As you may have already guessed, the answer to the riddle is none other than your very own...
What were you thinking? You PERVERT!
