She uses her fingers to stimulate the testicles and perineum, both violent and graceful. She pinches the testicles between her fingers, stretches them, twists and bends them, and grabs them with both hands and rotates them. She rubs the sensitive testicles with her long fake nails and gives an erotic massage to the perineum. She uses her nails, fingertips and palms to caress the glans in an endless, ultimate pleasure. She carefully and erotically runs her tongue over the slit of the glans, sucking it.
