The muscle-bound man, alone in his private sanctuary, fondles his massive, veined rubber cock, his eyes gleaming with anticipation. He runs it along his rippling abs, feeling the contrast of the smooth, cool silicone against his hot, sweat-slicked skin. Lubing it up, he begins to stroke, his grip tight and sure. His hips thrust forward, fucking the air with reckless abandon, his moans filling the room as he pleasures himself with his synthetic lover.
