Kara and the Big Dreamer - A Supergirl RP (Private with Dtrain34)
 

Nia Nal was making her way to her friend and coworker Kara Danvers' apartment. For some reason, her sister Alex has invited her over there instead of Kara, and she wondered why. Nia soon got the answer as she entered Kara's apartment, only to be greeted by the two arguing over something.

The two were arguing with Kara standing in a wet princess pull-up that was at her knees and her bright red spanked bottom on display “I mean it Kara! Get in that corner or I promise I’ll put you back over my knee!” She warned and Kara seemed to be put more in her place by that. She gave a small “hmph.” She stomped her way to the hot stinging chair in the corner.

With that taken care of she turned to their visited “Thank you for joining us, can I get you anything? Coffee? Tea?” She asked curiously

Obviously, Nia was very confused by that turn of events and sat down with Alex. "Uh... wh-what's going on exactly?" She asked, having never seen this side of Kara before.

She gave a small sigh “Straight to the point. I like that Basically my baby sister” she was interrupted by Kara’s insistence she’s not a baby “Kara!” She exclaimed immediately silencing her “Needs adult supervision. Basically around the clock. It used to be me until I took a new job that requires travel. I thought she could handle herself but look at the state of this place she clearly needs help. That’s why I called you. I know you two are close friends. She loves and respects you I see no better choice than you to be her second big sister. Are you interested?” She asked curiously.

Nia was still perplexed at the explanation. "What do you mean? Do you... do you want me to babysit Kara? Why is she like this now? She was never like this at work."

“She tries her best but yes. I’d like you to babysit my sister. Including diaper changes, bedtime stories, playtime, nap time, and anything in between for that naughty baby.” She responded

"She needs all that?" Nia was still struggling to come to terms with this. "But why is she so upset?"

“Yes she does. Look at this place she clearly cannot take care of herself so we’re gonna have to go the full nine yards. For why I’m asking you I think it’s obvious. You two are very very close I know you are. I see how she acts around you and more importantly I see how you can act around her. I think it’s a perfect fit.” She explained with a nod.

Nia was still taking this all in. "So is there anything else I need to know?

“I mean, you know how to care for children and babies don’t you?” She asked curiously as Kara’s bottom was still burning bright red to match her fact at what was happening in her own apartment.

"I suppose, but isn't Kara like... super strong?" Nia asked nervously.

“Not too strong for you to put her over your knee. Understand that?” She asked curiously tilting her head slightly with her arms crossed pointing to her sisters red bottom.

Nia realized Alex had a point. "Alright then. How long will you be out for?"

Hun that’s not what I’m asking for, listen… I know you’ve had a rough. I know you’re also a super powered girl. What I’m asking is for you to move in with kara and stay with her and basically join our family.” She explained with a nod.

Nia was surprised by the offer. "R-Really?" She had recently been estranged by her birth family after inheriting her mother's powers instead of her older sister, so the idea of joining another family interested her.

She nodded “Think of it as being a middle sister, now I have two little sisters, you and Kara.” She explained with a soft smile.

Nia started to tear up at the offer. "O-Okay!"

“Do you wanna start right now with being Kara’s new big sister?” She asked curiously patting the top of her head.

Nia nodded happily. "Of course! What should I do first?"

“We’ll, she’s upset and not quite dressed nor has she eaten so you can take care of those things right now if you feel comfortable with that?” She asked curiously

Nia nodded and went to go check on Kara, ready to punish her if necessary.

Kara blushed deeply as Alex left “C-come on Nia… we can talk about this… I can’t t-take care of myself.” She whined lightly still with tears in her eyes showing her immature nature.

"Kara, I'm sorry, but Alex put me in charge for a reason. Now, it's time to get dressed." Nia said as she approached Kara.

She gave a small whimper but simply shook her head “I-I refuse… I can’t take this I simply can’t I’m an adult!” She squealed out stomping her foot firmly on the ground showing a slight tantrum.

Nia crossed her arms and adopted a stern expression. "You know Alex gave me permission to spank you if you misbehave, right?"

Her face immediately dropped and she shook her head as her still pink bottom wiggled “N-no! No need for that!” She squeaked out bouncing up and down willing to do anything to avoid more spankings.

"In that case, it's time to get ready for work." Nia replied, secretly relieved she didn't have to spank Kara.

She stayed blushing but nodded softly holding her hands up to be picked up. She went out on a limb on her mind that this would be going the whole nine yards.

Nia managed to pick up Kara with ease and took her to her dresser to get some clothes on.

She gave a small whimper clinging to the other girl slightly getting used to Nias soft touch reminding her of Alex in a way.

"Do you have anything you want to wear?" Nia asked.

“C-can you choose?” She asked nervously hoping against hope she wouldn’t be reduced to being diapered be her best friend, someone she’d been a mentor to. The embarrassment was extreme.

"You know either way, I'm going to have to put you into a diaper, right? Alex told me to." Nia replied.
