Knocken, the insatiable stud, can't resist the allure of public play. Today, he's picked the winding staircase of an old, quiet building. His cock strains against his jeans, eager for release. He unbuttons, letting his thick, veiny cock spring free. He jerks, the sound of his hand against his flesh echoing in the silence. The risk of discovery, the taboo of his act, only serves to heighten his pleasure. His strokes become more urgent, his grip tighter, and with a final, powerful thrust, he comes, his hot cum painting the cold stone steps.
