A couple of nights later

Batgirl quickly makes her way back to the batcave where Spoiler and Black Bat are currently sparring and the only ones in the cave when Batgirl arrives. Giving them a quick hello, she tells them Harley gave her some info on the changes and she is going to see what she can learn from it. Sitting at the batcomputer she was intending to update it with information about Harley's changes, but she decides maybe not to. She rationalizes it by thinking if she adds that in she would need to come clean about what happened, and she would rather not do that. But she has to do something, so she puts in the computer the changes that do not include the new dick. But what did she learn? Harley said it just happened, didn't she? Sudden overnight change, which is in line with what others have claimed, but this is the first time it is someone they know. Unfortunately, that is not much information, so she logs out of the computer and moves to watch the other two bats spar.

She watches silently as they spar, but her eyes start to drift down a bit. Steph and Cass really have nice asses, Steph's is bigger though. Babs blinks a lot as she registers what she just thought, maybe she should call it a night.

"Good work you two, I am tired from patrol, so I am going to head in, don't stay up too late."

"Night Babs, we won't." Steph replies.

"Goodnight." Cass says simply.

Babs changes into her civvies and leaves the cave and makes her way home to the apartment she shares with Steph and Cass. Upon arriving she takes a quick shower, which is needed after the night she had. She also puts her suit in the special washing machine they have and then crashes in her bed for the night.

The next morning, she wakes up early, grabs some fruit for breakfast, and goes on her morning jog. As she does so she cannot help but check out the asses of the women she sees. She shifts between admiring them, and realizing that she is doing so and averting her gaze in embarrassment. This occurs throughout her entire day. That night she decides to call it early, claims to not be feeling like herself, Steph and Cass show some concern, but she waves it off claiming the power of a good night's sleep will be all she needs.

Sure enough the next morning she wakes up with new determination. So what if she likes checking out women's asses? They are wonderful to admire, she just needs to not be obvious about it, don't want to make anyone uncomfortable, or get caught. Her day goes like normal, she once again watches Steph and Cass spar, and does her best to not get caught admiring their very nice asses, although part of her thinks they would be better bigger. Eventually it is time for her to go out on patrol, hopefully her new hobby doesn't affect her superheroing.

After some time, the so far dull night becomes interesting as Batgirl notices Catwoman on a rooftop, Batgirl quietly lands behind her and takes a moment to admire her lovely ass before speaking up. Wait, is it bigger than it used to be? Licking her lips, she then addresses the other woman.

"What are you up to Catwoman?" Catwoman looks over her shoulder and smiles.

"Hello Batgirl. I am up to nothing that concerns you." with that she suddenly drops off the roof and Babs chases after her without thinking. While chasing her she has to try hard to focus on where she is going and not on the perfect ass she is chasing after. Almost tripping over herself once or twice due to failing to not check out Catwoman's ass she is just able to keep up as Catwoman enters an apartment. Still a bit thrown off by her new desires and not wanting to lose her target she makes the mistake of quickly following her in. Upon entering the apartment she notices it is dark, and realizes she does not see Catwoman, suddenly she is grabbed from behind, struggling to break free and failing she looks over her shoulder to see Catwoman is smirking at her, before Batgirl can say anything Catwoman releases her with a chuckle.

"You are off your game Batgirl, you could barely keep up. Something distracting you perhaps?" Batgirl turns bright red."

"N-no, not a-a thing. Shut up."

"My my, so flustered are we girlie, what has you so worked up." Unknown to Babs she has been inhaling pheromones once again since she entered the apartment. "Hmm, I think I know." With that she turns around and puts her hands on the wall and leans over to show off her ass. "Maybe this has got your attention?"

Babs cannot help but stare as she bites her lip, swallowing heavily she speaks up to deny the allegation. "So what if it has?" Wait, that is not what she meant to say.

"Then let me give you a better look" Catwoman says as she unzips her outfit taking it off, letting Batgirl see her bare ass. Batgirl bites her lip again to hold back a moan at seeing the most amazing ass she has ever seen come into view. She rubs her thighs together as she realizes how horny she is, she wants Catwoman, wants that ass. Without thinking she falls to her knees to get a closer look.
