The wall's aperture reveals a secret world of carnal pleasures, untouched by judgment or light. A new initiate, trembling with excitement and nerves, presents his stiff cock, engulfed by the unseen. His grunts echo in the small space as unseen hands and mouths work him, their rhythm and pressure unknown, but oh so right. He's a puppet, strings pulled by the dark, his body responding to the anonymous touch, building, building, until he explodes, his seed spilling into the void, swallowed by the silent, skilled lover on the other side.
