The Baby Cure Book Five: AB House: ABDL, Age Play, Regression, Sissy
Marie smiled. "I want to ride with you, Sister."
Kelly liked the idea. She moved forward on the rocking horse and Marie climbed onto the back. When Marie's arms were snuggly wrapped around her, she began to slowly rock. The horses wooden pommel was pressed against her diaper and Marie's lumpy diaper was pressed against her back. The girls rocked together and Marie buried her nose into Kelly's neck.
Kelly had graduated from the Nuvo Natalle Clinic into her next phase of treatment. Today she's moving to AB house to meet her new house mate, another grown up baby named Marie. The two become fast friends and, after Kelly discovers Marie's secret, they become even more than friends. "The Baby Cure Book Five" is a 3300+ word short story.
