The day I went out again with my sister, sparked by a walk. My sister, who has a habit of wetting and soiling herself, pees in her diaper on the ropeway and defecates inside it on the observation wheel. This episode thoroughly captures those moments. Initially a bit tsundere, my sister gradually becomes shy and submissive each time she has an accident, slowly turning sweet and adorable. At the start of the walk, we switch her into a diaper in the car before heading to the harbor town. Later, she wets herself on the ropeway, changes diapers in a restroom before eating crepes, soils herself on the observation wheel requiring another diaper change, and upon returning home, experiences diarrhea and further excretion, gets her bottom wiped, and is dusted thoroughly with baby powder until completely white. Finally, there's a YouTube-style review of absorbent panties. Each scene is carefully depicted, conveying the sister's transformation and cuteness throughout this connected story. Some scenes may contain background noise, but you'll be able to fully enjoy their charm.
