Eriko undresses and enters the bath, carefully washing her large buttocks and anus with body soap, highlighting her soft, glossy skin. She then sits on the edge of the bathtub, exposing her anus, and inserts several enema nozzles one after another, filling herself completely. Overwhelmed by intense bowel pressure, she rushes to the toilet, unable to hold back. This scene captures the fusion of natural bodily response and erotic expression.
