Cassidy

On the other side of the crib, another person yawns, the pacifier in her mouth falling as she stretches, arms bumping up against Sam. The brunette bangs of her neck-length hair framed her face. Her white-pink baby-tee bodysuit paraded in stark contrast to Sam's far less infantile green pajama shirt and pants. The edges of her diaper leg cuffs poked out of either side of her rainbow-covered onesie, bulging and sagging against the snap-crotch.

Cassidy was sleeping on her back, the form-fitting fabric accentuating her shapely features as she rolled to face Sam, eyes cracking open to reveal her baby blues.

"Mornin' Sis," she yawns. "You up already?"

Sam nods while she was adopted only recently; Cass's been with the Weavers as long as they've been in town. A childhood friend who came with them when they arrived and who signed up to be adopted as their adult baby not long after.

"Uh, yeah, sorry if I woke you up. I guess I still haven't fully adjusted..."

"Sis, don't worry. I know it can be a lot to take in at first. I know it was for me when I moved in with Mom and Momma." She chuckled, breezy and light. "It took me so long to start callin' Mom Mom instead of Kris."

She nuzzled into Sam's nape. They'd both grown up in regular, grown-up America, but Sam had bounced from foster to foster home in American suburbia, while Cassidy grew up in Appalachia, growing up not a million miles from the house where they lived now. She'd moved in with people she knew, not near strangers who decided to take her in.

Cassidy still talked with her family sometimes, splitting her time between home, attending the local community college, and the local auto shop where she worked as a mechanic.

The adoption made her Sam's 'foster sister,' and she was trying to help coax and coach her into the family, but it was still the early days.

"Is somethin' bothering you, Sis?" She asked, her head nestled against Sam's neck. "You seem tense."

"I-" Sam gulped. "I really need to pee, but I don't- I can't- it's just... a lot."

"It's okay, Sis," Cassidy reassured her gently, sitting up. "Here, let me help you, okay?"

Sam let Cass's arms wrap around her, rubbing soothing circles over her stomach. "Just relax, Lil' Sis. It's perfectly natural, remember? Nothin' to be worried about."

Sam let herself ease into her embrace, Cassidy's warmth, the soft fabric of her onesie, and the faint smell of the shampoo in her hair.

Sam let herself relax, relax enough that she could feel her bladder at ease, feel the sense of relief in the bottom, feel the growing heat flow, and spread outwards into her waiting diaper.

"See, Sis? Doesn't it feel good to just let it go?" Cassidy says, continuing her warm embrace. "It feels really good for me, especially when your diaper is warm after it soaks it all up 'n presses it against your princess parts. After a while, it gets cold and clammy, but that's when ya fetch Mom or Momma to change you so ya don't get a rash."
