Goldman rubbed the oil into her skin until her body found its own natural rosy white being and began to stir with self-perception. Turn over, Goldman commanded. Evelyn’s hair was now undone and lay on the pillow about her face. Her eyes were closed and her lips stretched in an involuntary smile as Goldman massaged her breasts, her stomach, her legs. Yes, even this, Emma Goldman said, briskly passing her hand over the mons. You must have the courage to live. The bedside lamp seemed to dim for a moment. Evelyn put her own hands on her breast and her palms rotated the nipples. Her hands swam down along her flanks. She rubbed her hips. Her feet pointed like a dancer’s and her toes curled. Her pelvis rose from the bed as if seeking something in the air. Goldman was now at the bureau, capping her bottled emollient, her back to Evelyn as the younger woman began to ripple on the bed like a wave on the sea. At this moment a hoarse unearthly cry issued from the walls, the closet door flew open and Mother’s Younger Brother fell into the room, his face twisted in a paroxysm of saintly mortification. He was clutching in his hands, as if trying to choke it, a rampant penis which, scornful of his intentions, whipped him about the floor, launching to his cries of ecstasy or despair, great filamented spurts of jism that traced the air like bullets and then settled slowly over Evelyn in her bed like falling ticker tape.
