The tiny shower stall becomes Paul's private sanctuary, the sound of the water his only companion. He leans against the cool tile, his cock aching with need. He takes it in his hand, feeling the weight, the heat, as he begins to stroke. The water cascades down his body, tracing paths along his muscles, tickling his balls. His movements become more urgent, his grip tighter, his breath coming in ragged gasps. He imagines forbidden acts, taboo desires, pushing him closer to the edge. With a final, desperate stroke, he comes, his body shuddering as he paints the shower wall with his forbidden release.
