The guard tapped his foot impatiently outside the door of the cell. Inside, the Joker sat on the corner of his bed and hummed along to the beat, a glazed expression on his face. He had been inside Arkham for almost two months now but was now merely biding his time until he was broken out - he insisted that jail is in fact an ideal space for scheming. However, having finished all such plotting weeks ago, he was now enduring the monotony of prison life solely for the entertainment of his psychiatrist.

'Hmm, Dr Harleen Quinzel' sighed the Joker to himself. 'My very own little Harley Quinn.'

Dr Harleen Quinzel had been working as a psychiatrist at Arkham for little over a year when the Joker had came into residence. Fascinated by his case report and crazy demeanour, she had asked to be assigned to him despite her lack of experience. Following several sessions, the Joker had also developed a fascination for Dr Quinzel. He spent his time inventing new personas and anecdotes just to watch her attempt to figure them out. The remainder of his days consisted of dreaming up the chaos he intended to ignite inside her.

That afternoon the Joker relived his latest fantasy. As the guard's foot hit the floor repeatedly outside his door, he closed his eyes and imagined Harley in front of him.

'You oughta wear something a little more revealing my sweet, a closed blouse like that makes a man like me dream up some pretty nasty stuff,' He licked his lips and leaned forwards on his elbows.

'I'm sorry, you're just going to have to keep those thoughts to yourself,' she replied curtly, propping her glasses further up her petite nose.

'I didn't give you a reason to apologise, I gave you a strong suggestion which I suggest you take.'

The Joker looked Harley in the eye and then gestured at her blouse.

'You know this is against the rules,' she frowned.

'Do I look like the kind of guy who plays by the rules?'

Harley looked at him exasperatedly.

'Now be a good girl,' he cooed.

The Joker stood and walked around to her chair. Harley's hands slowly raised to her top button as she looked up at the Joker. She couldn't help herself from both shrinking slightly and growing wet at the same time. Seeing him in such a position of power unlike the usual chained-to-the-desk situation she was used to finally allowed her mind to run free of the shackles that kept him away from her. There were in fact multiple reasons why she had insisted on taking on the Joker's case, some of which she would rather keep personal…

The Joker reached down and brushed her hands away, tearing open the rest of her blouse to reveal her full breasts. A further motion freed her nipples from the fabric of her bra, leaving them taught and ready for his touch.

Back in his cell, the Joker hummed lowly to the tapping, as he felt himself grow harder under his hand.

He spun the chair around and grabbed Harley by the backs of her knees, lifting her onto the table.

'Well this changes the situation sightly, hmm?' he cackled. Harley nodded slightly, wondering why the guard had not come in and whether she would actually want him to or not. She felt the strength of the arms holding her on the table and the slender muscular waist between her knees, deciding that her body had already discarded any desire to stop.

'You'll address me when I speak to you.' The Joker looked down at her sternly, pushing her further onto the table.

'Yes, Mr J' Harley whispered as he ran his fingertips over her nipples, flicking each in turn. Dragging his nails down over her stomach, he hooked the waistband of her trousers, inching them down whilst leaving trailing red marks. Her shoes were next discarded, leaving her naked except for her skimpy lace thong.

'Well, well, well… who's a naughty girl after all?' He smirked.

'Me, Mr J,' Harley replied quietly, blushing under his intense gaze.

'Good girl. I've wanted to do this for a long time Harley,'

'Me too, Mr J,' Harley realised the truth in her words, biting her lip as she felt a burst of excitement between her legs.

'Hmm, I can see that,' He replied, dragging his finger over the damp fabric that covered her pussy. Harley moaned, shuffling closer to his light touch. He laughed, withdrawing his finger.

'You have to work to deserve that,'

Harley moaned and moved her arms against him, surprised by his lack of resistance. Sitting forward, she cautiously began to remove his scrub top. Sensing his impatience, she became swift, finally laying her eyes on his lean, scarred figure. After his pants disappeared, he pushed her back again, only allowing her a glimpse of his erect cock. She smirked slightly, seeing that it was as big as his ability to wreak havoc on the city of Gotham.

'What's so funny?' His face appeared in front of her, his hand encircling her neck.

'I just got so lucky Mr J, I didn't expect this when I signed up,' She squeaked out, her eyes widening as he pushed her knees apart, one hand on his cock.

'Is that so, Harley? I don't believe your lies. Lying is for bad girls, and bad girls get spanked,'

He spun her over so fast that she cried out, following up with a sharp smack.

'What do you say to that, Harley?'

'Thank you Mr J,' she gasped as the next blow landed across her ass.

Still humming, the Joker grasped his cock, dragging his hand slowly along it until he felt the wetness of his precum. Imagining the feel of Harley beneath him, he pulled back on the shaft, feeling blood coursing through him as he began to stroke in time to the rhythm of the guard's foot.

Making himself wait, the Joker revelled in the power he had over Harley's body. He could almost smell the sex coming off her. He reached down and tested her wetness with one finger, pleased with the ease with which it slid over her clit. With a moan, Harley shifted her hips greedily. He began to rub over her clit, slowly tantalising her as she felt sparks of pleasure build up rapidly. Tightening his grip on her neck, the Joker pushed two fingers into her, stroking the walls of her hot pussy. No sooner had he begun, he pulled them out and forced her to taste them.

'How do you taste?'

'Good, Mr J. Why don't you try me?'

The Joker sat back, amused.

'Hmm, so you want to play cheeky with me then, do ya Harley?'

He spun her over again, dangerously close to the edge of the table. Her arms were pinned above her head in his tight grip as he smirked down at her. She refused to back down in her response, hungry for his attention. Sensing this, the Joker decided to play along - he already felt as though he had waited several eternities to oblige. Maintaining his intense gaze, he dropped his head to inhale the scent of her sex then allowed the tip of his nose to trail closer towards her pussy. His tongue flicked out, striking her clit to create fierce sparks of pleasure. Harley cried out, her eyebrows scrunched together as she tried to contain them. Never before had she imagined she would see those scars in real life from such a position. He licked her steadily until he felt her beginning to tremor, when he suddenly surged over her, the tip of his cock resting on her pussy lips.

'How much do you want me Harley?' he growled into her ear.

'More than I've ever wanted anything Mr J' she replied, hooking her knees over him in an attempt to pull him closer. He resisted, smirking at her desperation.

'Please, Mr J,' she whispered.

The Joker felt himself grow harder than ever before, his vision blurring with need. He roughly thrust into her, feeling her hot pussy clamp around him. He closed his eyes and began to fuck her, slowly and deeply. Harley threw her head back and moaned in pleasure. The Joker shifted to press hard against her G-spot and began to fuck her harder and faster. She cried out louder, gripping the edge of the table and squirted around his cock. The Joker groaned, slowing down to inspect her cum that was coating his cock as he slid in and out. He hadn't thought that he was capable of growing this hard. One hand grasping her breast, he began to brush her clit with his other in time with his thrusts. Almost immediately, he felt the strength of her clenches increase as her pussy got closer to climax. Harley could barely breathe, the strength of the building orgasm so great that she couldn't stand to open her eyes for fear of the sight of his cock inside her sending her into oblivion. The Joker thrusted faster and more aggressively as he too began to reach climax. He dropped his head, groaning as he spilled his cum deep into her. Harley screamed out, shuddering around him with the power of her orgasm.

The Joker looked down at his cock, still curved upwards with arousal and shiny with cum. He threw back his head and laughed maniacally until the tapping outside his cell stopped. Composing himself, he staggered to his feet as the guard's face appeared in the window.

'Get back! You have a visitor,' it shouted.

The door opened.

'Good afternoon, Mr J' said Dr Harleen Quinzel, lowering her glasses.
