Sumire is a housewife who, since her child became independent, has found herself with too much free time and growing bored. One day, she learns about a solo delivery job and decides to take the plunge. The work turns out to be more enjoyable than expected, and soon, exciting encounters begin to unfold. Today, a regular older customer places an order. She checks the time, rings the doorbell, and delivers the package—only to be suddenly kissed by the man. Yielding to desire, Sumire lets him make love to her completely before leaving his room. Another day, she delivers a package to a younger man who confesses, "I've loved you for so long," pulling her into a tight embrace. Though flattered—especially since she finds him cute—she has another delivery to make and must leave. Yet driven by the urge to respond to his feelings, she kneels down, takes his hardened cock into her mouth, and swallows his cum before departing. Later, when she visits his place again, she says, "Let's continue from last time," and proceeds to savor every inch of his body with pleasure.
