My clandestine existence bears a striking resemblance to my step-sibling and I

I've always been the mysterious figure in the background, the silent observer of my step-sibling and her family. My existence is a secret, a taboo that's never been spoken of. But when I'm alone with my step-sibling, the line between reality and fantasy blurs. The forbidden becomes enticing, the taboo, a thrill. She's not my sister, but the thought of touching her, tasting her, is irresistible. Her body is a treasure trove of forbidden delights, a playground of taboo pleasures. Her pussy is a garden of desire, a beaver that's been untouched for years. But I'm not just any man. I'm a monster, a man with a cock that's as big as an antique rifle, a cock that's as hairy as a yeti's balls. I'm a man who's been drinking from the fountain of youth, a man who's as horny as a hound dog. And when we're together, the room fills with the scent of sex, the air thick with the taste of taboo.
