While shopping for his wife's present at a department-store cosmetics counter, he meets beauty advisor Sara Futaba and cannot look away from her glamorous air, glossy full lips, and seductive gaze. When he later returns with his dissatisfied wife, Sara notices their cold relationship, presses close, and tempts him with a surprise kiss under the pretext of testing smudge-proof lipstick. Her soft lips and long tongue tangle deeply with his until his mind melts, drawing him into an affair filled with full-body licking, intense tongue kisses, sex, and a creampie behind his wife's back.
