The erotic masterpiece: a futanari's intimate moment with a steed, shrouded in whispers of precum and desire

From behind, a 1girl, a futanari, sat on all fours in an 8k, high-res realistic masterpiece. Her large thick hoop earrings glinted in the soft light, her red lips curved into a sultry smile. Her brunette hair fell in loose waves around her shoulders. Her perfectly proportioned body, completely nude, was accentuated by the play of shadows and light. Her erect penis, tucked away yet prominent, sat between her large, full pussy lips. The small testicles hung low, a sign of her phimosis. A horse, an animal of desire, stood behind her, its massive body dwarfing her. From the side, one could see her perineum, glistening with precum, and her soles resting on a stool. The scene was a photograph of a pretty, tall girl, a futanari, in an eerie quietude, beneath a tree whose branches formed a canopy over her.
