The pure and inexperienced protagonist suddenly gains the ability of a special express curse object with an exhibitionist fetish. He receives a request from married woman Asuna Hoshi, who says, "Before I actually end up doing something perverted in public, I want you to let me experience a simulated exhibitionist act." Appearing before him is Asuna, a voluptuous woman with H-cup explosive breasts and a big ass. Though initially hesitant, she accepts the situation when kissed through his clothing. As the virgin boy experiences a simulated blowjob using a dildo, his excitement grows uncontrollable. Holding onto her thighs in a tight miniskirt as handrails, he indulges in the simulated public sex experience. When touched by the lingerie-clad Asuna, he begins passionately groping her breasts and ass, while her pussy gets increasingly wet. In this intense moment, Asuna herself, overcoming her confusion, kisses him first, licks his nipples, and gives him a real blowjob. Riding him in cowgirl and doggy style, she slams her big ass against him, shakes her massive tits, and takes his cock deep with piston-like thrusts, ultimately receiving a creampie. This intense, intimate experience becomes the highlight of the story.
