Ohh....yeahhhh......

This is a useful tool, commonly found in the range of 6 inches long, the functioning of which is enjoyed by members of both sexes. It is usually found hung, dangling loosely, ready for instant action. It boasts of a clump of little hairy things at one end and a small hole at the other. In use, it is quickly 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 in 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 When finally withdrawn, it leaves behind a juicy, frothy, sticky white substance, some of which will need cleaning from the outer surfaces of the opening and some from its long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.

Well loyal readers, what is it? Speculate in the comments.
