The man's alone time takes a dark turn as he indulges in his favorite form of self-torture. His cock, already throbbing with anticipation, is bound tightly, the rope cutting into his skin like a lover's bite. He picks up a handful of nettles, their innocent green belying the brutal sting they're about to inflict. With a deep breath, he presses them against his cock, hissing at the sudden, intense burn. His strokes become frantic, the pain fueling his desire, as he chases the elusive orgasm that always seems just out of reach in this dance of pain and pleasure.
