The Bat-Signal flickers, but tonight, it's not a criminal that draws Batman's attention. His hand wanders south, finding his hard, eager cock straining against his suit. He unzips, letting his monster spring free, already leaking with anticipation. The cool cave air sends shivers down his spine, but his desire burns hotter. He grips his shaft, his thumb swirling over the sensitive head, his other hand cupping his heavy balls. His hips buck, fucking his fist, his grunts echoing off the cave walls as he chases his release, his powerful body tensing with each thrust.
