He can think of a few

Batman unable to hold himself back any longer fell on Harley pinning her to the ground. Harley gasped into Batman's firm kiss and moaned as he worked his way down, "Oh yes, mister B more give me more."

'She doesn't get to tell me what to do,' Batman thought narrowing his eye's. Batman let up on Harley and pulled her over his lap. She gasped as he ran his hand up her leg and around her hip. "What, uh, what are you doing mister B." Harley asked as Batman laid his hand on her ass.

"You've been a bad girl Harley," Batman whispered, "Bad girl's get punished." Once Batman finished speaking he brought his hand down hard. Harley gasped feeling the sting of the slap through her short shorts. Again and again Batman brought his hand down taking pleasure from each of Harley's pained gasps. Harley edged closer to Batman with every spank and began, unintentionally, rubbing herself against his manhood. Soon spanking the girl through her shorts wasn't enough for Batman and so he ripped off the shorts and leaned down to Harley's ear, "You do know that was just a warm up, right?" Harley whimpered.

Batman gently rubbed Harley's ass for a while, eliciting sighs and moans from the young woman, before bring his hand down more firmly than ever. Every pant, whimper, cry, and moan that came from Harley went straight to batman's groin. Batman watched as Harley's mouth formed an 'O', Harley turned her head and buried her face in Batman's chest. Batman continued to rain down blows until he felt Harley's body spasm and go limp, 'did she just orgasm?'

Sure enough the girl had indeed orgasmed from Batman's punishment, 'So Harley's a little masochist slut,' Batman thought a cruel smile dotting his lips. Batman began to rub Quinn's ass softly until some life returned to her. She turned her head to Batman looking up with tear dotted eyes, "Was I a good girl?"

Batman smiled, "Yes Harley you were a very good girl," Batman moved the girl off his lap, "and good girls get rewards," he said as he pulled his manhood out from his costume. The girl practically tackled him as she wrapped her slender fingers around Batman's cock and kissing him on the lips. Batman pulled her deeper into the kiss as Harley jerked him off.

Eventually Harley broke away from the kiss and said, "If I'm a really good girl can I have a treat." Harley's face turned to a pout, and she tilted her head down, 'she's learning her place,' Batman thought, 'good.'

"Yes, Harley," Batman said, "but only if you do a good enough job."

This sent Harley into overdrive as she dove down onto his cock taking the head into her mouth and licking it with her tongue. Harley licked her way down the thick, meaty, rod moaning the entire time. 'Vicki orgasmed just from giving me a blowjob this morning, maybe the effect has gotten stronger,' Batman thought before all his thought were replaced by the need to dominate Harley.

As Harley went to suck on the head again Batman **** her head down into deep throating him. Her arms flailed as she began to ****, Batman pulled her up. Harley gasped for breath and said, "I've never had something that big down my throat before."

"Well it's not getting any smaller," Batman growled as he pulled Harley toward him again, "Now be a good girl and get to work."

"Yes master," Harley said with a pout, "but can I go a little bit slower."

"Just do what you can," Batman said his voice adopting a comforting tone.

Harley set out dutifully sucking more and more of Batman's penis moaning and spasming as she went down. Batman slowly began thrusting himself up more and more before he could feel his cock touch the back of her throat. Harley began going up and down faster and faster until she brought her head away from batman's manhood. She looked up at Batman and said, "Please fuck my throat master. Your slut needs you."

'Who am I to deny a request like that,' Batman thought grabbing the back of Harley's head and thrusting into her throat. He thrust until he felt himself approaching his limit, again he felt Harley spasm as an orgasm rocks her body. 'Oh, yeah the effect is definitely getting stronger.'

Batman Bottomed out with one last thrust and burst in Harley's throat. Batman streamed cum down Harley's throat until he thought she'd drown and he pulled out. Batman continued covering the girl's face for a solid minute until he was done, 'Shit, I'm cumming more too. I wonder what other surprises I'll discover?'

Harley laid on the ground rolling around mewling for a few more minutes, in the meantime Batman called the Batmobile to him. Eventually he kneeled down at Harley's side and whispered, "Harley," getting no response he shook her shoulders, "Harley, are you awake?" Soon Batman chose to roll Harley over, he did not expect to see her crying. 'I knew it, I fucking knew it. Damnit bruce why couldn't you hold yourself back, now you've-.' Batman's thought were cut off by Harley saying, "You're gonna leave me aren't you."

"What?" Batman asked.

"Now's the part were you swoop off and the police come to arrest me," Harley said with tears streaming down here face, "after you give me all this pleasure, you make me yours, make me fall in love," Harley's eyes grew wide as she realized what she said.

"I-uh I mean," Harley was cut off with Batman covering her mouth.

"Shh," Batman said calming the girl and pulling her into a hug. 'So now what do I do,' Batman thought as the exhausted girl fell asleep in his arms, 'I could leave her for the cops,' Batman thought, but something inside told him that she was his, no one else's. Batman felt he couldn't leave the girl less out of pity for her and more out of being possessive of his new toy.
