In the heart of Arkham Asylum, the air was thick with anticipation and mischief. Nightwing found himself in the familiar confines of Harley Quinn's cell, his heart pounding in his chest. The sultry blonde, clad in a tight white vest and baggy orange trousers, was a tantalizing sight to behold. Her blonde pigtails bounced playfully as she flirted with him, a mischievous glint in her eyes.

"You're gonna have to seduce me for that information, Nightbutt," Harley purred, her voice dripping with seduction. He smirked, stepping closer to her, his eyes never leaving hers. The electricity between them was palpable, and Nightwing could feel his cock stirring in his pants.

With a swift move, Nightwing closed the distance between them, his hands finding her waist. Harley let out a delighted giggle, her body pressing against his. He leaned in, capturing her lips in a passionate kiss. Their tongues danced, exploring each other's mouths as their hands roamed over each other's bodies.

Nightwing broke the kiss, his eyes twinkling with mischief. He gave her a playful smirk before his hand came down on her ass with a loud smack. Harley yelped, but her eyes sparkled with delight. Nightwing repeated the action, each spank sending a jolt of pleasure through her body.

He spanked her repeatedly, each smack echoing through the cell. Harley writhed under his touch, her moans and whimpers filling the room. The sound of skin meeting skin was music to Nightwing's ears, and he could feel his cock straining against his pants.

Nightwing's hand slipped under her trousers, finding her soaked pussy. He groaned at the feel of her wetness, his fingers sliding easily inside her. Harley gasped, her body arching in pleasure. Nightwing's fingers moved inside her, hitting her G-spot with expert precision.

Harley's moans grew louder, her body trembling under Nightwing's touch. She was close, her body on the edge of an explosive orgasm. Nightwing could feel it, his fingers moving faster inside her. "Give me the information, Harley," he growled, his voice low and husky.

With a whimper, Harley gave him what he wanted. Nightwing pulled his fingers out of her, a satisfied smile on his face. He pushed her down on the bunk, his cock aching to be inside her. She squealed with delight as he roughly yanked her trousers down her creamy white legs. She let out a soft moan while biting her bottom lip as he slid down her panties.

Harley spread her legs for him, her pussy glistening with wetness. Nightwing slid inside her with one swift thrust, both of them letting out a gasp of pleasure. He began to move, his hips pounding into hers. Harley wrapped her legs around his waist, her fingers digging into his back.

Their bodies moved together in perfect harmony, each thrust sending waves of pleasure through them. Harley's moans grew louder, her body trembling with pleasure. Nightwing could feel his orgasm building, his cock throbbing inside her.

With a final thrust, Nightwing came, his cock spilling its load inside her. Harley followed him, her body shuddering with pleasure as she came around his dick. They collapsed on the bunk, their bodies slick with sweat.

Nightwing looked down at Harley, a wicked grin on his face. "Next time, you should just give me the tip I need," he teased. Harley just laughed, her eyes sparkling with mischief. "We'll see about that, Nightbutt," she said, then added, "I might enjoy you giving me the tip I need too much."
