The room is filled with the soft hum of a mechanical companion, its rhythmic pulsations echoing the man's own heart rate. He leans back, legs spread wide, as the machine's silicone appendage teasingly traces the contours of his ass. He gasps, arching his back, as it penetrates him, setting a steady pace that mirrors his own stroking. The room is a symphony of moans and mechanical whispers, building towards a shared climax.
