Two girls in sailor uniforms perform a series of 11 pissing acts, including outdoor standing peeing, pissing in plastic bottles, crawling while peeing, and accidental leakage. A highlight is a tea party scene by the river, where a girl in a kimono prepares matcha but lacks hot water. Instead, she fills her teacup with her own urine and forces the other girl to reluctantly drink it. The director discovers them, grabs the urine-filled teacup, and facially bukkakes the girl in a humorous and erotic finale.
