When they went into the room Sara internally whoops when they hear the gentle breathes of the sleeping Kara Danvers/Zor-El sprawled out on the bed with her arm draped over the edge. The blond runs, with Ava following closely behind, grabbing the duvet and shimmying her way to the unconscious alien.
When they make it onto the bed Ava hums and nods 'I feel now is the best time to say... she's hot I approve'
Sara looks confused 'You approve... oh you think I slept with Kara'
'Well didn't you?'
'Nope, Alex yes but not Kara. poor thing hadn't figured out she was a lesbian yet, didn't think it as my place to drag her out of the closet kicking and screaming' Sara explains, and Ava understands. Right until Sara starts using Kara's breast like a beanbag chair 'But these are just as perfect as I suspected. Very nice'
Ava sighs 'Captain Lance, that act was very inappropriate, plus we have a mission to complete'
'KARA, HEY SUPERGIRLWAKE THE FUCK UP! See nothing we can do besides wait for her to wake up naturally. So hop on a tit and enjoy yourself for a little while, we can't DO anything until she's awake and able to help us'.
Ava hums before following Sara, a little surprised that despite the name 'Girl of Steel' her skin was as soft and pliable, her breast still juggled when she shoved into it, trying to catch a break somehow.
'Nice isn't it?' Sara asks, Ava smiling blissfully, and nods
'She's so soft, and the smell'
Sara practically purrs 'Yeah, it's something that can only be described as Kara, and is quite an addictive scent' she smiles before nuzzling the pale orb, happy she gets to share this moment with Ava of all people.
So what now?
Sara, seeing Kara was going to be out cold for a little longer she decides to expand her knowledge of the giantess, exploring her sexy body in a way never seen before. Ava can explored with her, but could also remain where she currently was, quietly and contently deciding to curl up in Kara's cleavage for safety
OR
While she couldn't tell, Sara's yelling did reach Kara's brain, the Kryptonian slowly pulling herself awake, surprised to see 2 people using her large, bare breasts aa furniture and now she can add confused, interested and a little horny to the mix too.
