A lone enthusiast explores the intense, solitary pleasure of cock pumping and urethral sounding. The scene opens with a close-up of the glistening, engorged cock, already dripping with anticipation. A specialized pump is applied, slowly drawing out every sensitive inch, the user's breath hitching with each rhythmic suction. The pressure builds, the user's moans filling the room as the pump reaches its maximum, the cock throbbing and purple with need. The pump is removed, and a gleaming metal sound is carefully inserted into the now gaping urethral opening. The user gasps, the sensation intense and overwhelming, as the sound is slowly fed deeper, the cock twitching and leaking pre-cum with each inch.
