Author's note: My thanks to my editor. Even more for this story than usual, as she had to struggle with my straying into new pastures.

She followed the unicorn all day, far from her shelter, much further than she'd ever travelled. He was her friend. He protected her when the beasts came; they were no match for his size. Nor his agile horn. He foraged for food with her, showed her where the best things were. Sometimes when he looked at her, she understood what he required of her. She cared for him: washed dirt from the places he couldn't well clean on his beautiful coat, and in his proud fastidiousness she knew he was grateful to her. Sometimes he would be gone for days -- days filled with aching emptiness inside her.
When he returned from these partings he gave her recompense, using his tongue on her pleasure-place till her exhilaration made their wetness mingle. Even his breath on her was exciting. She used her hands on him sometimes, felt from his look when he needed that, and she knew what she must do. Her excitement was unbounded when she watched the stuff surge from him. She had tried to please him with her mouth. This was harder; her mouth was so tiny against his hugeness, but she relished the taste of his glutinous spend when it covered her face.
She knew he yearned for more, and understood what it was. She had watched other beasts doing it and it always excited her. But on the occasions she had sought to give him full release, it had proved impossible. When she crouched under him offering herself, he'd been unable to enter. If she tried to help, lifting an arm behind herself to guide him, the force of his enthusiasm knocked her down and his wetness on her back ended every attempt.
Today was different, a change from all that had passed between them before. She understood from his behaviour at morn that something was new. Impatient head-tossing, gossamer mane flying, something in his eyes she hadn't seen before. She knew to follow him, up into the hills above the forest, stones hurting her calloused feet. Through the pass, cold and wet, till she was shivering and exhausted.
He allowed her to climb on his back. He'd never done that before, though she had oft wanted to feel what it was like. Now at last she knew, her muscled legs clutching his silken flanks. Leaning forward onto his neck, his spine rubbed the pleasure-place, and it tingled through her discomfort and weariness. He picked his way carefully down from the pass, into a wooded valley overhung with strange trees.
Light was fading when he stopped before a cave by a stream. She slipped from his back. He whinnied at the scent of her wetness, nudged her two mounds with his velvet nose. He knew her need and she was grateful. She removed the skins which covered her. Lay before him on the soft grass, gazing in the dark pools of his eyes as his head bowed and his long tongue protruded. The feelings rushed upon her at his attention, excitement and need welling. She watched his rod lengthen till it almost brushed the grass beneath him. After the first surges shook her, she scrambled to crouch under him, immersed in his strong scent, seeking to succeed where she had failed before. Yet again she collapsed before his thrusting. His cries of frustrated lust pierced the evening as the spend fell on her back and his hooves, so close to her, pounded grass to mush in frustration.
Afterwards he went to forage before the final orange light slipped behind hills on the other side of the valley. She ate from the supply she'd garnered on the journey, drank from the stream, felt herself full and content. He returned before she slept and lay beside her, his graceful white form granting her warmth.
