In a private, stark room, David Neptun, a man of imposing figure, stands tall and naked, save for a blindfold. His muscular body is tense, anticipating the impending pain. A bundle of fresh, green nettles lies at his feet, their delicate leaves concealing a hidden, stinging bite. Neptun's erection juts out, a stark contrast to the rest of his body, betraying his arousal. With a deep breath, he grabs the nettles, wrapping them firmly around his shaft. The initial contact is a shock, a sharp, stinging sensation that makes him gasp. But he endures, sliding the leaves up and down his length, the pain morphing into a strange, exhilarating pleasure.
