In the dimly lit room, Sonny's eyes feast on his sister's black lingerie-clad body, her breasts straining against the lace, her panties damp with her arousal. He can't help but imagine his cock sliding into her wetness, her moans filling the room. He strokes himself slowly, his sister's eyes fluttering open, catching him in his taboo fantasy. She licks her lips, her eyes never leaving his cock, before whispering, "What are you waiting for, brother? Make our fantasy a reality."
