Called into a room under the pretense of a cosmetics survey, office lady Mari finds herself having to remove her makeup and go barefaced to test the products. Claiming it's for skin analysis, the examiner begins touching her all over, gradually easing her tension. Though initially resistant, Mari slowly grows aroused, her pussy starting to get wet as she enters full sexual mode. Seeing a cock for the first time in a while, she eagerly licks it like a virgin experiencing it anew. By the time penetration begins, she's completely surrendered to her desires, transforming into a woman who spews one lewd phrase after another. She loses herself entirely, immersed in an intensely passionate experience.
