Girls' no-toilet sleepover "Omuyuri." This time, cute twintail Hana-chan and mature beauty Rira Kubo participate. Both are wearing cloth diapers for the first time and have never seen adult-sized disposable diapers before. After struggling to put on the cloth diapers, they change into pajamas and prepare for bed. As part of their nighttime routine, they play with toys like baby bottles, pacifiers, and a doctor's kit.
Hana-chan decorates Rira's hair with ribbons, scrunchies, and bear-shaped clips, transforming her into a childlike figure. They begin sharing memories of bedwetting and decide to reenact the experience. Lying down, holding hands, they promise, "If I start peeing, I'll squeeze your hand." But it's hard to go while lying down. Eventually, their bladders reach the limit, and yellow stains spread across the sheets, wet pajamas clinging to their buttocks.
Hana-chan's long-held urine forms a large yellow puddle on the bed. While cleaning up the bedwetting mess and putting on disposable diapers, their neediness peaks. They take turns breastfeeding from bottles in this indulgent, affectionate documentary-style video.
