Batman, consumed by a taboo desire, invites his secret ally to a forbidden tryst in the Batcave. The air thick with anticipation, they strip, Batman's enormous cock throbbing with need. His partner, hesitant yet eager, offers their tight, untouched ass. Batman, growling, lubes up and slowly pushes into the welcoming hole, stretching it wide. He begins a punishing pace, grunting as he pounds his partner's ass, the sound of their flesh slapping echoing in the secret chamber.
