Harley was sucking hungrily on Dick's prick, making the young man moan and groan in pure delight, while an over-fucked rested next to them. Nightwing felt his release coming when suddenly Harley stopped sucking on his cock. He looked at
her with surprised and pleading eyes.
"Sorry, Bird-brain, but I have a task for ya!" Harley explained. "You go find Black Bat and make her one of us, while I bring Pussy-cat to the fun-house so that she can keep Ivy company."
Nightwing nodded obediently, as he couldn't do anything else. As soon as Harley and Selina were out of the Batmobile, Dick drove away to find his sister. That was the easy part. All he had to do was to contact Cass and request for backup. Fifteen minutes later,
Nightwing was standing on a rooftop, waiting for Black Bat to come. She landed behind him, never suspecting that her adoptive older brother would have laid out a trap for her.
The first ropes that bound her legs were only meant to distract her and give Nightwing the occasion to spring on her and bind her wrists. He had her pinned face first on the dirty floor and was about to rape her virgin cunt.
She turned a panicked look over her shoulder to which her responded with a smirk. "Ssh, don't worry, Cass. This won't hurt you for too long," he huskily whispered in her ear as she felt him ripping off her pants to expose her pretty pussy to Gotham's harsh
cold. "I promise you, sis, you will love every second of it," he promised as she felt him slide his length over her nether lips.
No matter how much she tried to resist him, Black Bat's body was responding in kind, pleasant electricity running from head to tow and juices dripping out from her pussy. When he felt she was wet enough, Dick plunged his rod inside his sister's puffy cunt.
Her initial pained sobs and whimpers soon turned into moans and groans of pleasure, as Cass was being humped by her brother. She started jerking her hips in time with his thrusts. After a few minutes of plowing through her tight vagina, Dick released his seed,
while she too cried out in climax.
After he released her, Cass turned to lie on her back, facing Dick. Nightwing kissed Bitch Bat hungrily as he penetrated her wet dripping pussy again and humped her even more eagerly.
