Push her ass back

Catwoman leans forward more, pushing her ass back into Batgirl's face, forcing her backward until she lands on her butt. Selina is enjoying the power trip, but is also losing her patience, the bat won't do anything, just staring at her ass.

"Come on Batgirl, touch it, worship it, you know you want to."

Babs is so far gone she does not even think of resisting the command, she reaches out and caresses the wonderful ass in her face. Her entire world is consumed by this ass, that and the heat between her legs, she rubs her thighs together trying to find some friction while she starts kissing and licking at the ass, worshiping it like she was told. She is a bit surprised to hear Catwoman start actually meowing, unaware of how Selina was changed. Meanwhile, with Selina she is enjoying the attention and her act is slipping; because she was told to she was able to act like her old self, but the whole time she wanted to be a cat again, now she is falling back into her real self, she moves down to all fours with her ass still in Batgirl's face. Batgirl has zero complaints about this and she starts eating Catwoman's ass, thoroughly enjoying herself.

But, all good things must come to an end, Selina remembers that Batgirl here needs her dose, so she moves away, with Batgirl moving with her, forcing Selina to move quicker, pushing Batgirl down before spinning around and sticking her cock in Batgirl's face. Batgirl does not even think and instead moans at the sight and smell and almost inhales the dick. After the attention given to her ass Catwoman does not take long to cum, meowing loudly as she does, and Batgirl dutifully swallows every drop, the semen further changing and corrupting her, Catwoman pulls out of her mouth and once more commands her.

"Strip."

Knowing what will come next Batgirl eagerly takes off her costume and then bends over, presenting her ass to Catwoman, who is naked but for her ears, with Batgirl naked but for her mask. Batgirl wiggles her ass enticingly and Catwoman plows into her pussy fucking her hard while leaning onto her, both of them on all fours with Batgirl's face up against the ground due to Catwoman's weight, not that she minds. The two go at it for a while, Batgirl losing track of orgasms, and Catwoman coming multiple times, partway through Catwoman switches holes which Batgirl is delighted by, loving the cock in her ass as much as in her pussy. Eventually, Batgirl passes out and Catwoman pulls out and staggers over to the bed, leaving Batgirl on the floor, she too passes out.

Later Batgirl wakes up, remembers what happened, and puts her suit back on quickly heading back home and slipping into her room quietly, not wanting to raise suspicion due to being out so late. Making sure the coast is clear Barbara once again puts her suit into the wash before going back into her room and passing out once more in her bed.
