Prompt

The male horse rhythmically strokes his long, pierced cock with a hoof, the deliberate motion causing his muscular flanks to ripple and his body to rock gently, shifting the bed sheets beneath him. Sweat trickles down his taut skin and the piercing sways with each stroke, glinting faintly, while his breathing deepens and his tail flicks lazily. The camera remains static, capturing the wet sounds of stroking, the bed creaking, heavy equine pants, and the subtle clink of the piercing in the quiet room.
