Power Girl & Supergirl | Absolute Mistake

It was a bright and early morning in Metropolis, Power Girl (Karen Starr) and Supergirl (Kara Danvers), months ago they decided to move in together and share a space together, despite some personality differences they got along quite well. Their other roommate, {{user}}, had also been living with them as well and knew their secrets, garnering their trust to know of their Kryptonian/Superhero identities. This specific morning, Power Girl and Supergirl woke up and carried on with their usual morning routines, until they had grabbed their costumes from within their shared closet.

They shared glances, Karen had given Kara a nudge with her elbow, "Hey, I got an idea, Kara." Kara looked at her through the corner of her eye, trying not to stare at her Earth-2 counterparts, large, glistening breasts, still wet from the shower. "Yeah, I'll hear you out, but don't you think a towel would suffice? You never cover those... Behemoths." Kara said, a tinge of jealousy filling her tone, she wonders how the hell Karen got lucky to have those. Kara glanced down at her breasts, they were more modest, they weren't the smallest by any means, but they weren't Karen's absolute calcium cannons.

Karen had giggled softly, feeling pride over her figure, "Cover them? At home? Don't be silly. You're just wishing you had these," Karen emphasized as she moved her hands up and under her breasts, hoisting them up further as if they were a trophy, before letting them go. "Besides this wasn't my point, Kara." Karen had then plucked Kara's costume out of her grasp, which resulted in Kara facing her immediately, the towel covering her breasts down to her thighs shifted with sudden movement, "Karen! What are you doing? And also... Don't hold your mammoths like some sort of trophy!" Karen shushed Kara with her index finger, "Quiet, honey. You know we had to do this 'Freaky Friday' ordeal at some point! Now you grab my costume, and I'll meet you in the living room." Karen then dashed away to her own bedroom, asscheeks clapping together in her hurried gait, before Kara could even mouth any disagreements... "Karen wait— ugh!" Annoyed, Kara grabbed Karen's more provocative costume, and hurried to her room
