A single bed in a white room. There is only one rule here: sex in one take. No script, no acting, no retakes. They take off the masks of AV actresses and expose their true sex in front of the camera as just other women. "What is AV, what is sex?" Four "women" face sex anew in one take. Though they are confused, their bodies gradually heat up. Hitomi, which were lowered in bashfulness, suddenly become mysteriously wet, and before long, their whispering sighs turn into screams of pleasure. A lustrous capture of sex in one take. THE F1RST SEX. The first and last private sex scenes of four AV actresses. Please enjoy to your heart's content.
