This work features school-distributed bloomers throughout, faithfully recreating the authentic gym uniforms once actually worn in physical education classes. Since these bloomers, originally sold for use in school lessons, are now difficult to obtain, preserving visual records has become essential to retain the fading memories of that era. The video documents both a plump girl and a slender girl wearing the bloomers, posing erotically, masturbating, and reenacting the secretive act of having sex while wearing bloomers, just as it was quietly done back then.
