Women who can feel it in secret, one door and one curtain away, are quietly having orgasms! A woman's nature gets wet because she's in a situation where it's not okay to raise her voice.

○A college student couple is in a room with their parents next door...In a library where silence reigns...An office worker couple looking for stimulation is on an empty office floor...An AD asks his girlfriend to make a phone call to his parents...An AD and a female doctor disguised as patients are in a large hospital room with other patients on the other side of the curtain...If they say anything, they'll be found out! Cover your mouth with your hand and desperately hide the sounds that leak out! That situation evokes even more pleasure! An omnibus recording of amateur couples and hunter ADs who met on the street and challenged themselves to get some pocket money!
