Aiko started working part-time at a convenience store to help with household expenses. She caught the eye of B-kun, a college student working there part-time, who was smitten with her youthful appearance despite being in her late 20s. Aiko, who had long been sexless with her husband, gradually became drawn to B-kun. One day, during an argument with her husband, she cheated with B-kun. B-kun, besides his youthful vigor, was a huge fan of ass and could get hard for doggystyle no matter how many times he ejaculated. During work hours, they engaged in countless rounds of doggystyle creampies in various spots within the store, even enjoying perverted acts while customers were around. As female hormones surged, Aiko's skin became radiant and she grew increasingly beautiful.
