"Now it's been a long day and I'm tired, so you are going to stay put while I get out of these clothes and then you're going to do your little job and sleep next to me" Lena explains, placing Kara gently on the bed and unbuttoning her blouse, causing the blond to turn deep red "Oh and if you try to escape you're sleeping with my ass rather than my boobs little one...." she stops her threat and smirks, just as she removes her skirt "Unless you'd prefer that" Lena teases, turning around and wiggling her butt in Kara's direction "If that's the case I'd prefer you just tell me love, as that way I won't be mad at you and spend the first 10 minutes angrily crushing you under my ass" she jokes but Kara still gulps, Lena may have a nice rear, but she'd rather not feel it dropped on top of her, especially not with intent to harm behind it.
So Kara remains in the middle of the bed, seeing Lena strip down into a black bra and panty set, then putting a light grey sleep shirt on over them and turning to her with a content smile "Night night little one" she purrs, fingers wrapping around Kara's middle before sliding into bed and holding her to her chest "Given your size, I'm sure you'll be happy my boobs are so big to keep you warm "Lena smiles down at Kara, who looks up with an unreadable expression "Well, unless you're prefer my butt..." Lena stops when she feels Kara wriggle and see her shake her head from side to side
"I'm good, your boobs are great Lena, no need to move me" Kara shouts, getting a pet on the head for her troubles
"That's good, in fact since you love them so much, how about a closer look" Lena smiles and pushes up her shirt and moving Kara under it, slipping her between her bra and her milky bosom then readjusts herself and wrapping her arms around her core as if hugging herself, pressing her breasts further around Kara, sealing her in "Oh you feel great in their Supergirl, the real thing is better than any toy" she coos, leaning down to kiss the little tuft of blond hair sticking out of her cleavage "Goodnight my love, get ready for the rest of your life" she whispers, then settling on her side for a peaceful night, Kara tries to move but pinned by her friend's mummeries.
The next morning Lena wakes and runs her hands through her hair, feeling something was off but couldn't quite put her finger on it... until she feels something wriggling in her cleavage. It was then the previous night came back to her and she grins, Supergirl currently in a losing battle with her breasts, oh what a way to start her day.
What next?
1) Lena still has to go to work, and since she feels so good there already decides to leave Kara where she is, her current position also allowing her to function as a secondary bra in case her current one snaps like it did a couple days back
2) Lena has work to do and an alien to examine, so decides to bring Kara to L Corp subtly, by sliding the girl down the back of her pants and have her play seat cushion until she has time to work in the lab this evening. She's the Girl of steel, surely she can survive a human sitting on her lap... well entire body ;)
3) Today was one of Lena's rare days off, something the CEO is very happy for as it means she has nothing else to do but play with Kara, looking forward to feeling the former goddess writhe and squirm under her fingers.... and tongue. Maybe she can even get Kara to pleasure her if she plays her cards right
