Batman, exhausted from a long night of fighting crime, returns to the Batcave. He strips off his cape and cowl, tossing them onto the table with a sigh. His muscles ache, but there's a different kind of tension he needs to relieve. He unzips his suit, his hand reaching inside to grip his hard cock. He strokes it slowly, his mind wandering to the forbidden thoughts he usually keeps locked away. He imagines Superman's strong hands on his body, Wonder Woman's lips around his cock. His breathing grows ragged as he picks up the pace, his fist flying up and down his length. The sound of his hand meeting his flesh echoes in the cave, a lewd symphony that only he can hear. He comes with a grunt, his seed spilling over his hand, a secret pleasure he'll never share with the world.
