The Bat and The Clown
Read the storyDuring a confrontation with the Joker in an old building, the Joker flees while Batman gives chase and the rest of the Bat-Family deals with his goons. Batgirl goes in the direction Batman took off in to assist him against Joker. She notices a door ajar and quietly peeks inside the dimly lit room, there she sees Batman and Joker standing before each other in front of a table quietly talking about how long they think they have before someone tries to find them and, much to Batgirl's shock and horror, the two start making out and stripping naked, although Batman doesn't remove his cowl. The moment Joker drops his pants Batman turns Joker around and forcefully bends him over the table and starts having angry sex with him, repeatedly thrusting and smacking his hips against the Joker's buttocks while the Joker laughs in pain and pleasure, begging Batman to knock him up.
