Alone in his room, Lucario, a burly, tattooed man, begins his evening ritual. His massive, veiny cock throbs in his hand as he strokes, his precum glistening in the dim light. He lets out a guttural groan, his body tensing as he edges closer to release. Suddenly, a soft knock at the door interrupts his session. It's his stepsister, seeking refuge from their arguing parents. Caught in the act, Lucario's embarrassment turns into a heated challenge as he dares her to join him. She hesitates, then tentatively reaches out, touching his slick shaft, igniting a taboo dance of desire.
