Nightwing dropped from the fire escape, boots hitting the gravel with a crunch. His suit clung to every muscle, the kevlar stretched tight over his thighs and the obvious bulge in his crotch after a long night of chasing assholes through Bludhaven. She was already there, leaning against the ledge, skirt hiked up just enough to show she wasn't wearing panties.

"About fucking time," she said, voice low and rough. "I was about to start without you."
He didn't waste words. He crossed the roof in three strides, grabbed her by the hips, and spun her around so her ass pressed back against his growing hard-on. "You want this cock? Then shut up and take it." His gloved hand slid between her legs, fingers finding her already slick pussy. Two thick digits shoved inside without warning, pumping hard while his thumb ground against her clit.
She moaned and pushed back, grinding on his hand. "Fuck yes. Harder."
Nightwing yanked his codpiece open, freeing his thick cock. It slapped against her ass, heavy and leaking. He didn't tease. He lined up and drove in balls-deep in one thrust, stretching her tight cunt around him. She cried out, hands gripping the ledge as he started pounding, hips slapping loud against her ass in the quiet night.
"Goddamn, you're soaked," he growled, one hand fisting her hair, the other reaching around to pinch her nipple through her thin top. "This pussy was made for Nightwing cock." He fucked her rough and fast, the wet sounds of her cunt taking every inch filling the air. Sweat beaded under his mask. He could feel her walls clenching, trying to milk him already.
He pulled out, spun her, and shoved her to her knees. "Suck it clean." She opened her mouth and took him deep, tongue swirling over the head before swallowing him to the root. Spit ran down her chin as he fucked her face, holding her head steady while his balls slapped her jaw. "That's it. Choke on it."
When he was close, he hauled her up, bent her over the ledge again, and slammed back inside. This time he reached down and rubbed her clit in tight circles, driving her over the edge. She came hard, cunt pulsing and squirting around his shaft, juices dripping down her thighs. He didn't stop. He kept thrusting through her orgasm, chasing his own.
"Fill me up," she begged, voice wrecked. "Come in this dirty pussy."
Nightwing grunted, buried himself to the hilt, and unloaded. Thick ropes of cum pumped deep inside her, overflowing and leaking out around his cock with every pulse. He stayed buried, grinding slow as the aftershocks rolled through both of them.
They stayed like that for a minute, breathing hard, his cock still twitching inside her. Then he pulled out, tucked himself away, and gave her ass a sharp slap. "Same time tomorrow. Don't be late." He fired his grapple and vanished into the night, leaving her dripping and satisfied on the rooftop.
