In a dark, smoky den, four demon succubi, their bodies a tantalizing mix of flesh and shadow, gather around a trembling, bound sissy. The shemale demon, Daiko, takes the lead, her voice a husky whisper as she begins the anal training. "You will learn to love our cocks, human," she purrs, running a forked tongue along the sissy's quivering lips. The demons take turns stretching the sissy's virgin ass, their massive futa cocks glistening with lube and spit. The sissy, eyes wide with fear and pleasure, follows Daiko's every instruction, eager to please his new mistresses.
