The hum of the vacuum echoes in the room as he positions it, its nozzle gaping like a hungry mouth. He guides his rigid cock towards it, feeling the first touch of suction. The sensation is intense, a RAW, mechanical pleasure that makes his balls tighten. He fucks the nozzle, his hips moving in a rhythmic dance, the vacuum's power pulling him deeper into ecstasy. His moans mingle with the machine's hum, a primal soundtrack to his forbidden solo indulgence.
