WINNER: My Sisters Keeper

I couldn't believe how lucky I was, not only that it had been my sister, Amy, who walked in on me wearing a diaper, but that both her and her girlfriend, Siska, were both totally into diapers as well. Siska stood above the two of us, taking photos, and I wasn't sure I could make noises let alone words, with how much I was blushing.

~~~

"Roll over, both of you." 

I totally didn't like this, but Alex was alight with excitement.  I blushed and held my shirt down over my green animal-print diaper, looking sideways at my sister in her lavender one.  This was supposed to happen! 

"Siska, maybe we could have the night to ourselves?" 

But my girlfriend smirked. 

"Why have one baby," she said, "when I could have two." 

Alex and I protested at the same time: 

"I'm not a baby!"

~~~

"You're definitely a baby," 

I managed to snark through blushing grins, still not able to look my sister in the eye. But I was a baby and that meant she was a damn baby, too, and that was that. 

"Your Mommy," I risked, not knowing if that's what she called Siska or not, but it seemed a safe enough bet, "says you're a baby!"

~~~

I puffed out my cheeks in frustration and looked up at Siska, who gave me that same knowing smile.  Early in our relationship, I told her about my love for diapers.  How I thought they were sexy, how I felt submissive wearing them, and how much I loved to use them.  But her interests were a little different.  She wanted to treat me like a baby.  But I'd said a thousand times: I wasn't a baby!  And now Alex said it, and... I felt my cheeks catch fire and I couldn't look up at Siska.  I wish I had never walked in on my sister...

~~~

"You know, Alex, your sister Amy here is a true baby; I bet she's more of a baby than you are. She loves to USE her diapers, I bet you don't do that." 

At the challenge I shook my head and pouted, looking over my shoulder. 

"I do so too use my diapers!! Almost ALWAYS!" 

Then I realized what I said and buried my face in the stuffies on my bed. Omg.

~~~

I looked at Alex with a bit of surprise and then up at Siska.  She nodded at my sister and I rolled my eyes.  Fine, she wanted to play?  I could play.  I crawled up next to Alex, on my stomach, and flashed my butt for Siska to snap another picture.  I looked over at her shyly and took her hand in mine. 

"Hey... it's okay.  Come on - we can do it together." 

She gave me a nervous smile and nodded her head.  My girlfriend watched as my sister and I simultaneously wet our diapers.
