The next four days are a whirlwind of sex and spending for the beautiful bad girls.

The first night was relatively quiet. The girls took turns reinforcing their dominance over the enthralled Dark Knight. Harley was the first to subdue the Batman. She removed his belt, and commanded him to lay on the bed. Now completely under the control of the two villainesses Batman **** but to comply. While Harley was busy getting their present ready, Ivy was thinking about what they needed over the next few days. They still had Bruce Wayne's credit cards. She'd make sure to put them to good use. Ivy looked over at Batman, now tied to the girls' bed. He was beyond gorgeous, but Ivy still wished they hadn't let Wayne die...

"Uungh..."

Batman moaned as Harley pulled down his pants and went to work sucking his cock. Lusty slurping sounds echoed throughout their room as Harley gave Batman one hell of a blowjob. About an hour later Harley came and left Batman to Ivy's mercy while she went to shower. Ivy licked and kissed all over their captive's body, ending their session with a deep kiss on the lips once again binding his will to her. When the girls woke the next morning, Batman laying between them, tied and gagged Ivy smiled down at him.

"Well, love, you'd better get used to this. You aren't going to escape. Not this time."

Harley yawned as she set about dressing herself. Sliding her nightie off she put on some plainclothes and tidied up their room a bit.

"So, are you going out, Red?"

"Yeah. Well still have Wayne's money and it'll be a bit before anyone realizes he's gone. I think I'll go out and get some more stuff. Some presents, and some... necessities."

Ivy turned her gaze toward the bound Bat as she ended her sentence. Obviously if the two villainous vixens wanted to keep Batman around for a while they'd need more than a few ropes and lipstick. Ivy knew she could get some chemicals to put Batman even deeper under their control. She smiled evilly as Batman struggled against his bonds. Right now her lipstick only worked for a little while before the victim regained control. Of course, Harley would be here all day today. Batman wasn't going anywhere.

"Have fun, Harl. Make sure..."

Ivy walked over to Batman and gently stroked his cheek, grinning. Batman's eyes widened with anger as Ivy smirked, knowing he could do nothing.

"... make sure he ENJOYS it as much as you do."

Harley giggled as Ivy left to procure their Christmas stuff. She tilted her head toward Batman.

"Oh, don't worry Bats... I'll take real good care of you today."

Harley sat on the Bat, slowly grinding her body against his as she peeled his gag off.

"Let me g-mmmph!"

Harley's lips covered the Bats, and she moaned into his mouth as she once again dominated his will with Ivy's special lipstick. The Bat fell silent as Harley continued to grind against him and kiss his body. Eventually she got bored of the teasing and began to fuck him rough. She clawed his skin as she rode his dick, barely able to contain her cries of pleasure. Batman was a great lay. No matter how much she hated him for always stopping her Joker she had to admit he was amazing at sex. She was hotter than she'd even been, except when she slept with Ivy, in a matter of minutes. Several hours later, she'd lost track of how many times she'd cum. Batman himself was a sweaty, exhausted mess. Lipstick marks peppered his entire body. As she finished up, Harley took of Batman's gloves and tossed them aside. She knew he kept several tools in there that might help him escape and no one wanted that. Ivy arrived with several packages a bit later, and the two went through them with glee while Batman once again regained enough will to weakly struggle to escape his gorgeous captors. Later that evening Harley was busy rummaging through their new stuff while Ivy was preparing to play with their captive. Harley squealed in delight as she found a camera and a glass case. She looked over at Ivy and the red-head smiled, turning her attention to Batman.

"For our collection, Bats. We'll take turns immortalizing our... fun with you. The glass case is for your belt. Something for us to remember you by once your gone..."

Batman would've snarled if he wasn't so doped up. Ivy climbed on top of him and kissed him passionately. She'd mixed some new chemicals into a more potent ****. Batman would be their **** soon enough. Ivy felt Batman's cock harden as she molested him. She licked and sucked on his neck for a while, before inserting his dick into her pussy. She rode him with abandon for a while, moaning all the while. Harley took several pictures, her own pussy getting wet from watching the intense love-making going on. After Ivy's time with him was up, she and Harley decided to test her new **** by questioning the Bat. They asked him all sorts of things, who he liked better between the two of them, what some of his weaknesses were, and even some dumb questions like what food he liked. They avoided anything about his true identity. Both girls had decided to unwrap that little gift on Christmas day. When they were done questioning him Ivy kissed him one last time and set him, gently, into dreamland.

"Y'know, having him here helpless like this is pretty hot."

Ivy smirked as her partner's assessment of their situation.

"We'll have to kill him sooner or later, probably... We can't take too many chances with him."

"We can at least keep him 'til Christmas though, right, Red?"

"Yeah, I think that'd be fine. Tomorrow, I think we can have him drive us around while we use up more of the late Mr. Wayne's money."

"Oh, goodie!"

Both girls looked down at the **** Batman and giggled. Time passed slowly for Batman, but the girls felt like their time with him was too short. It was Christmas eve. Ivy had just finished fucking Batman again and took a look at the clock. It was 11:58. She called Harley over. It was time. Both girls got their captive ready. He was still under their control, but had a measure of his will back. Harley caressed him while Ivy sat on his bound form. She reached down and cupped his chin, while her other hand gently took hold of his mask. She looked back over at the clock, then back to their captive.

"It's midnight, Darling. Time to unmask."

She began to peel his mask off, Batman weakly groaning in protest.
