A treat for her. Her lover places two or more well
lubricated and
inspection gloved, fingers, into her anus, then firmly massages her G-spot and it's related squirt glands, through several thick layers of muscular vaginal and anal tissue, against her
pubic bone. She goes off like a gun if you do it right! Don't spare the lube! See also asspuppet, cornweasel, etc.
