Chapter 1: Stake out

The night air was thick with anticipation as Batman and Harley perched on the edge of the grimy rooftop, the Gotham skyline sprawling before them like a sleeping beast waiting to be awakened by their nocturnal dance of justice.

The silence was broken only by the occasional distant siren wail and the rhythmic thumping of their hearts. Batman's gaze was unwavering, scanning the shadows for any sign of movement, while Harley, ever the impatient one, had found a rather... unorthodox way to pass the time.

With a mischievous glint in her eyes, she had taken his fat cock in her mouth, swirling her tongue around it like it was a lollipop she hadn't sucked in years. She moaned with delight, the vibrations echoing through his shaft as she deep-throated him, her cheeks hollowing with each eager bob.

The sight was nothing short of mesmerizing, but Batman remained focused, his hand gently resting on her head as he guided her in a steady, practiced rhythm. Hours had ticked by, but the only thing that had changed was the slickness of his cock, the bulging of her cheeks, and the growing tension in his balls.

Batman's grip tightened slightly on Harley's head as she paused for a moment, letting his cock slide out of her mouth with a wet pop. She looked up at him with a grin that was both innocent and sinful, her eyes sparkling with mischief.

"Any changes, Batsy?" she purred, her voice thick with desire and the lingering taste of him. Despite the gravity of their mission, the sexual tension between them had reached a fever pitch.

He took a deep breath, the musky scent of their combined arousal filling his nostrils.

"Nothing yet, Quinn," he replied gruffly, his voice strained from the effort of maintaining his focus.

"Keep an eye out." But the truth was, his mind was racing with thoughts of how much longer he could resist the temptation of her hot, eager mouth.

He watched as she leaned back in, her red lips parting to welcome his cock back between them, and he couldn't help but wonder if maybe, just maybe, they could find a way to combine work and pleasure tonight.

The tension grew unbearable as Harley took Batman's thick cock out of her mouth again, her breaths coming in shallow gasps, her eyes never leaving his. With a knowing smirk, she reached up and gently took his hand from her head, placing it firmly on her cheek.

"You know what they say, Bats," she whispered, her voice a sultry purr, "variety is the spice of life."

Before he could respond, she wrapped her hand around the base of his shaft and brought it back to her lips, her tongue flicking out to tease the tip.

With a sudden, almost feral growl, Batman gave in to the desire that had been simmering just beneath the surface. He slapped his cock against her face, painting her cheeks with his precum mixed with her saliva, the smacking sounds echoing through the quiet night.

Harley's eyes fluttered shut in ecstasy, her moans growing louder as he smacked her again, her lips parting to catch his cock in her mouth once more, her movements more urgent now, as if the waiting had made the taste of him all the sweeter.

With a low growl of his own, Batman reached down and yanked Harley up from her knees, her red pants and panties slipping down to her knees with a suddenness that made her giggle. She looked up at him with a mix of surprise and excitement, her eyes half-lidded with lust as he grabbed her hips and spun her around, pressing her against the cold, hard surface of the rooftop's edge.

The wind picked up, sending a shiver down her spine as he bent her over, exposing her plump, round ass to the moonlit night. He leaned in close, his hot breath caressing her ear.

"Now, Harley," he murmured, "it's time for some variety." He didn't wait for a response, instead using his strong, commanding hands to spread her cheeks wide, revealing the pink, glistening folds of her sex.

The anticipation was unbearable, and without another word, he drove his cock into her, the sound of their bodies colliding mixing with the distant sounds of the city below. Harley let out a loud, animalistic moan, arching her back to meet each powerful thrust, her fingers curling around the gritty concrete as she felt him fill her completely. The stakeout was all but forgotten as they lost themselves in a passionate, desperate rhythm that seemed to shake the very foundations of Gotham itself.

"Oh yes, yes, yes, that's it, Batsy, fuck me bad," Harley moaned, her voice a desperate crescendo of pleasure as Batman claimed her from behind. He slammed into her with an intensity that sent waves of euphoria crashing through her body, her breasts bouncing with each impact against the rough concrete. Her pussy was a tight, wet sheath, gripping him like a vice as he pounded into her with reckless abandon.

The sound of their flesh meeting was a symphony of passion, punctuated by her gasps and his guttural grunts. Batman's hands tightened on her hips, guiding her movements to match his own, his fingers digging into her flesh as he pushed deeper and deeper, hitting that sweet spot that had her seeing stars.

Harley could feel her climax building, a storm of sensation that threatened to consume her entirely. She reached back, her hand finding his, and laced their fingers together, her nails digging into his palm as she urged him on.

"Harder," she begged, her voice a breathless whisper, "I want it all." And with that, Batman gave in to her pleas, his strokes becoming more frenzied, his cock a relentless force that claimed her over and over again.

With a final, earth-shattering cry of "Oh Batsy, I fucking love you!" Harley's body convulsed, her orgasm ripping through her like a tornado, leaving her trembling and gasping for air. Her pussy clenched around Batman's cock, her walls pulsing with the force of her climax, and he could feel his own release approaching, a white-hot pressure building at the base of his spine.

With a roar that could have woken the dead, Batman pulled out, his cock glistening with her juices, and painted the side of the building with thick ropes of cum. The sound of their ragged breaths filled the night as they both took a moment to catch their breath, their hearts pounding in their chests like the bass of a heavy metal concert.

Leaning forward, Batman's hands began to knead and caress the soft flesh of Harley's ass, his fingers digging into her generous curves as he whispered dark promises of what was to come. The roughness of his touch sent shockwaves of pleasure through her body, making her quiver with anticipation. He leaned in closer, his cock still pulsing with the aftershocks of his climax, and kissed the back of her neck, his teeth grazing her sensitive skin.

"You're mine," he murmured, his voice a seductive growl that sent a shiver down her spine. Harley pushed back against him, her ass cheeks pressing into his palms, urging him on.

"Take me, Batsy," she moaned, her voice a needy whine, "Make me scream." The fire in his eyes grew brighter as he positioned himself behind her once more, his cock already beginning to swell again with renewed lust.

This time, he would show her just how much she belonged to him, and how much she craved his touch. He slammed back into her, her wetness still clinging to him, and they were lost to the world once again in a whirlwind of passion and desire. The night had just begun, and Gotham would have to wait a little longer for its Dark Knight and his mischievous sidekick to emerge from the shadows of pleasure.
