Elsa and Anna's secret "Big Sissy, Baby Sister" time.

“Anna, come here sweety,” called Elsa from across the room in a rocking chair.

Anna stopped playing with her stuffed teddy-bear as she got on her knees and crawled over to her big sister. Elsa picked up her little sister and sat her down onto her knee, Anna putting her arms around Elsa’s shoulders as she propped her legs over the wooden chair’s arm-rest.

“Are you having fun, baby-girl?” Asked Elsa.

Anna shook her head yes with a muffled ‘mhm’, her mouth occupied by a proportional baby pacifier in her mouth. Elsa brushed one of her ‘baby’-sister’s pigtails into the right position as her other hand kept Anna upright.

“Well, good. I’m glad your having fun.”

Elsa reached down and felt her sister’s groin, feeling for her undergarment under the thin layer of fabric.

“Uh oh. Looks like someone wet herself. Do you know who it is?” Elsa cooed.

Anna, blushing heavily with embarrassment, shook her head ‘no’.

“Well I do, and she needs a new diaper right now,” said Elsa as she got up and carried her younger sister over to a changing table.
