Something new grows

When Harley unloads inside of her Cass cums again, she had no idea pleasure like this existed. Faintly she notices something feels weird at her crotch, since Harley is currently not moving she has just enough of her mental faculties to check, feeling down there she finds her clit and then, wait, another one? She cums again when she touches the new one, before she can think more about this she moans in despair as Harley pulls out of her, then moans again in delight as she enters her asshole, the second clit is completely forgotten about as she is once again consumed by pleasure.

Meanwhile, Babs is still eating Harley's ass and masturbating while doing so, she too has cum more than once, and she is thoroughly enjoying herself, although she is still jealous of Cass. Harley is also having a fantastic time, fucking one batgirl in the ass while the other eats her ass, her new powers able to corrupt their minds so that they love it. Babsy got so corrupted she brought Cass here to also be corrupted, some would consider that a betrayal, and if Cass were able to think right now she likely would, but she cannot. The only one who can is Harley, and Babsy a bit. It was quite fun learning how well the anal fetish took with Babsy, and it was also amusing to see Cass notice the change, before forgetting all about it. Little does Cass know it is not a second clit, but the beginning of a new dick, Harley has decided it would be fun to give Cass a dick like hers, with the pheromones and all. Of course, it will not just be a body alteration, she has a mental one in mind too. Speaking of, she feels an orgasm building, another fun aspect is while she can usually think during times like this, she too almost loses that ability as she cums, it is wonderful, and it helps her understand the power she has over the others.

Cass screams out along with Harley and does not even notice the changes yet, as usual there is the increase in bust and ass size, what can she say, Harley loves curvy women. But if Cass were able to pay any attention to herself, she would notice that what she thought was a clit was now clearly a small dick. But Harley wants that to be a surprise, so this time she continues fucking Cass' ass during and after her orgasm.

Two orgasms later, Harley pulls out. Impressively, Cass is conscious, incapable of thought, but awake.

"Get up ****."

Babs comes back to herself and stands up on wobbly knees, she did not cum as much as Cass, but still did, and it was wonderful. Cass on the other hand takes a minute, but she finally is able to think, and with a little help from Babs stands up. As she slowly becomes more aware she notices changes, first she notices is her ass is bigger, the reason that was first is Babs is already fondling it. Then she realizes her chest is bigger too, then the biggest surprise of all, she has a dick? She looks to Harley in confusion and gasps. Earlier Harley looked hot, but now, she looks radiant, a godly beauty, irresistible, the question she had in mind left her head for a moment.

"Hello ****, I see you noticed your new toy. It is lotsa fun. Kinda like mine, makes people horny, and they will love it when you fuck them. But there is another change."

"Ass. And boobs."

It is clear Cass is assuming those are the changes, Harley is going to correct her but Babs speaks up first, too excited to hold back.

"Mistress probably changed your mind too, more than just making you her fucktoy. Why do you think I have been so obsessed with asses?"

Cass moans when called a fucktoy, then her eyes widen when she realizes there is another change. She tries to think about what it might be but comes up empty.

"At random points, you will become uncontrollably horny, and need to fuck someone. Immediately. I thought it would be fun to start nowish. Whatcha think?"

"Now? Whaaaa."

Suddenly it hits her, exactly what Harley described, she needs to fuck, she looks to Harley who shakes her head, and even in this state, with no mind, no thoughts except fucking someone, she knows to obey Harley. She looks around desperately and sees Babs, her eyes light up, before Babs can react she finds herself bent over the desk like Cass was, then she screams out in pleasure as she orgasms while Cass enters her.

Cass is moaning and grunting as she fucks Babs hard and fast, and Babs is loving every second, her eyes closed she is moaning and gasping in pleasure when she feels something poke her face. Opening her eyes she sees mistress' dick and she eagerly takes it into her mouth. Her mind is fully gone, she cannot imagine feeling more pleasure than this. Being fucked in the ass by Cass while also sucking mistress off. It is heavenly.

Eventually Cass cums inside Babs and returns to herself, Harley empties into her mouth at around the same time. The only changes made where mental, and just ones to reinforce what was already done. Cass staggers back dazed and exhausted, she falls back into a chair and slumps down, and then passes out. Babs meanwhile gets off the desk and falls down onto the floor, her knees too weak she cannot even stand up, the pleasure had overwhelmed her, and she too passes out. Harley looks at them with a smirk and heads back to Ivy's place for some fun until tomorrow. They should be bringing the other batgirl tomorrow, and that will be fun.
