I do not own Batman or any DC Comics characters.

"Well that was quite a show Miss Kitty, but I think I can do better," a teasing voice declared from the darkness.
Catwoman sat up, still next to the recovering Dark Knight, and craned her head towards the voice.
"If that's you Harley, there's no need to hide," the satisfied woman stated, as she began to rise.
The shadows of the cave moved until a woman revealed herself in front of Selina. She held her hands behind her back while sticking out her chest, making her impressive breasts look especially large.
"It looks like we had the same idea," the new female said, crossing over to Batman, peering down at him.
"Great minds must think alike, but I would never accuse you of having even half a mind Harley," Selina insulted with a smirk.
Harley Quinn frowned at Catwoman momentarily, but began to skip over to her.
"So you think he enjoyed you better than he would enjoy me?" she challenged, pressing herself against Selina's naked form.
"Maybe we should find out," Selina said, surprisingly slapping Harley's plump rear end.
"You are naughty,' Harley said, an evil smile crossing her lips.
"If you put on a good show for me, I won't claw your eyes out," Catwoman said, slinking into the chair she had previously captured the Bat on.
Harley Quinn frowned for a moment, but then stuck her tongue out in defiance.
"I don't care what you think you are allowing, I'm here for some Bat-cock, and nothing can stop me from getting it," she spat, bouncing back over to the near-comatose Batman.
Selina had stripped Batman of all of his clothing except his cowl. He lied flat on the floor looking up at Harley. He managed to put a sentence together.
"Harley, something is wrong with the women of Gotham-," he started to say.
Harley had placed a finger on the Batman's lips and looked at him thoughtfully.
"Oh Bats, I don't care what you have to say about protesting this. The Kitty over there has had her way with you before I could get here, and I can't let that go unpunished," Harley said happily, her voice always had a sing-song quality.
"Look at me Mr. B," she said, standing back to reveal her body.
Bruce couldn't stop himself from looking at Harley's incredible body.
Selina's body was tight and fit, while Harley's was softer, thicker, and curvier. Her red and black costume clung to her skin, showcasing every part of her curvaceous form. The size of her breasts rivaled Selina's, and they looked just as soft. All of Harley's curves were amazing, but they all paled in comparison to the part that finished the masterpiece. Harley turned her body so Batman could see.
Harley's ass was enormous.
Batman stared at the bubble butt in quiet awe. It wasn't a mere bubble butt. It wasn't just a better than average heart-shaped ass. It wasn't just an ass that won't quit. This ass was two humongous lobes of pliant flesh. This ass jutted out as a shelf that could support the weight of a phonebook. This ass was two watermelons, swaying when it moved, daring to be squeezed. This was a gigantic ass of mammoth proportions.
The World's Greatest Detective could not stop his erection from starting. Harley looked over her shoulder to witness his growth.
"Oh Bats, do you like looking at my ass?" Harley teased. She spread her hand across her expansive buttocks.
"I think you should see more," she suggested.
Harley dug her fingers into her behind, and tore her thin costume apart. Free of the costume's restrictive material, her butt now revealed to be even larger than previously thought. The Batman's penis grew rigid at the sight of her ass coming free of its prison, swaying in the air.
"Oh he does like it!" Harley squealed.
Harley proceeded to tear off the rest of her costume, ravenously exposing the rest of her body. Her breasts sprung from behind the cloth, and bounced pleasingly. Her legs revealed to be long and sexy. Her body was as curvaceous as the Bat had hoped. Before the Batman had another thought, Harley faced away from him, and sat her gigantic ass on his chest.
"Look at this!" the naked woman gleefully exclaimed, grabbing the base of Bruce's giant dick.
His penis was rock hard and it twitched when Harley tightly grasped it. A small bead of pre-cum formed at the tip of his penis. Bruce moaned softly, anticipating a stroke that Harley refused to allow.
"I can't help you release Mr. B, not until you ask for something," Harley said, peering down at the throbbing penis.
"What is that?" Batman asked, his strength returning.
Harley wriggled her hips which made waves through her mountainous ass flesh.
"You must beg to bury your face in my big ass," Harley venomously revealed.
"Oh you're bad," Selina moaned, starting to rub her clit while sitting in the chair.
Harley looked over her shoulder while squeezing Batman's thick pole tighter.
"I won't do anything until you beg, stud," she said, raising her eyebrow while she waited. The Batman opened his mouth, sheepishly.
"I want...your ass in my face," he softly said.
"I can't hear you," Harley said, lowering her face so Bruce could feel her breath on his member.
"Stick your huge butt in my face Harley," Bruce said loudly, hoping he would finally feel her mouth.
Harley touched the tip of his rock-hard head with her tongue and waited.
"STICK YOUR GIGANTIC FAT ASS IN MY FACE SO I CAN LICK YOUR ASSHOLE," the desperate man yelled.
Harley shoved her ass backwards and forced Batman's face in between her bulbous lobes. Bruce's tongue reached out of his mouth until he found her tight asshole. Harley squealed as he began to feverishly lick her.
"Oh fuck, that feels so good," she gasped, right before encasing Batman's dick into her mouth.
Batman's mouth opened wider upon feeling his throbbing dick pass Harley's lips. He took the opportunity to return the favor by wrapping his mouth around her asshole, licking her passionately. Bruce was lost in hot, wet pleasure below, and his tongue tasted delicious taboo above. He was so immersed he hardly noticed Harley's huge, encasing butt wasn't allowing him to breathe. He gasped for air, but only when he was on the brink of suffocation.
"Do you love the taste of her asshole Bats?" Selina asked, rubbing her clit more vigorously.
"Do you absolutely love it?" Harley echoed, taking a break from her dick sucking.
"Yes, I love your delicious ass," Bruce admitted.
Harley sat up and rested her huge bottom on Batman's stomach. She grabbed his tree trunk of a cock and slapped it against her belly button.
"This is the thickest, most meaty cock ever, and I want to give it an award for being so obscenely giant and tasty," Harley stated.
"What award?" Bruce asked, his engorged member twitching wildly.
Harley smiled as she lifted herself over his penis and rested it in between her cavernous butt crack. Bruce moaned as the soft walls of her ass surrounded his dick.
"I bet you never thought you would love two ass cheeks so much," Harley said, clenching her butt together.
Batman moaned loudly as her warm lobes gripped him tighter. Harley took the sound as a seal of approval and began to shake her ass. Pre cum began to coat Harley's magnificent butt, as Bruce's cock bounced and swayed between her cheeks.
The testicles on the Caped Crusader began to clench, and he gritted his teeth as heaven washed over him. Harley continued to move her hips, pushing her lover to the edge. Batman clenched his eyes preparing for his inevitable climax.
Then Harley stopped.
"No," Bruce sighed, desperate to release the contents of his balls.
"No, no Bats. You can't waste all of your cum on the outside...I need it inside," Harley revealed.
Harley lifted her butt above Batman's rigid cock. Her cheeks slowly parted to make way for his enormous head as she lowered herself. Bruce's pulsing pole stopped when it reached the entrance of her tiny asshole.
"Oh, my hole is so small Bats. I may not be able to fit you in me," the temptress teased.
"Please..." Bruce trailed off.
