With the other two on the bed

"Sandy, on the bed on your back. Stephie, get her cock in your pussy, Babsy, sit on Sandy's face facing away from Steffi." They quickly move to do as ask, and in moments all are moaning in pleasure. But there is more. She gets on the bed and pushes Steph down, and thrusts into her asshole, it is clear Steph came as soon as she did so. Without her needing to tell her, Stephy starts eating Babsy's asshole. Perfect. Just a few days ago these bats were just friends and teammates. Hung out from time to time, worked together to fight crime. Now they are horny sluts for Harley and each other. Just look at them, Steffi is getting double penetrated by Harley and Sandy, Babsy is getting her pussy eaten out by Sandy while Steffi is eating her asshole. And they are loving every second of it, as evidenced by the muffled moans of Steffi and Sandy, and the not at all muffled moans of Babsy.

"Having fun Steffi? Enjoying having your mind be blank, devoid of thoughts? Only thinking of two things, getting and giving pleasure? I hope so."

Steph did not respond, the words barely registered, she heard Harley was talking, but was unable to comprehend what was said, doing so was simply too hard. Instead she just continue eating out Babsy's ass, why does it taste so good? And holy fuck Cass and Harley both feel amazing, her mind is completely melted, she never wants this to end.

Meanwhile Cass is also unable to comprehend, her mind is completely gone, her cock is in control, and it only cares about fucking Steph harder, she even came already but she is still unable to think. This is something Harley decided to add, since Harley is so close, the animalistic lust will never end. And if the pleasure of fucking Steph wasn't enough, Babs' pussy tastes so goddamn good, so good she feels pleasure from eating her out.

The only one able to hear and understand the words was Babs. While her mind is almost completely gone from the dual tongues inside her, enough is left to hear. But not enough to truly get what was meant. Who wouldn't enjoy this feeling? It is wonderful, nothing is better than pleasure like this, and she is eternally grateful to Harley for giving it to her.

Harley finally cums the first time, as usual Steph gets curvier, and there are no other noticeable changes. It will not be until later that they are noticed, for now, Steffi will simply become very vivacious while being fucked in every which way.
