The glowstick

The glowstick is when a man reams/guages the pee hole of his penis, big enough to put a flashlight in his pee hole. Then proceeds to turn on the flashlight with it in the urethra, so the penis then looks like flesh glowstick.

My mistress finally reamed my penis enough to put the maglight in it, it was the brightest glowstick i ever had. I then pounded her with the glowstick.
