Hitachi Magic Wand

subtle whir. thick
round head vibrating
slowly, she opens. gates to fantasy
it's all good, deep inside her mind. he is
always hard, ready. her clitoris licked
machine fast. frantically.
ache and want do not live here.
Her hips meet untiring vibration.
Her back arches. Muscles quiver and relax.
not earth-shattering, but enough to prevent spontaneous combustion.

A product sold as a portable massage wand, and shipped with a little pamphlet listing good pressure points and tension points to work on with the wand.

However, few people maintain that's what it is sold for, and it is doubtful that the company thinks that's what it's used for. Women know what it's really used for, and they continue to make it a very successful appliance.
