Seconds before closing time, overtaxed office worker Ikumi Kiritani gets hit with a data error that's guaranteed to keep her late. Her colleagues shuffle quickly past on their way out, barely sparing a glance at her slumped in defeat at her desk... until one man, Inaba, stops to reach out a helping hand. They tackle the work together in the now-empty office, joking around as they go, and the topic of dating comes up. Ikumi laments her lack of boyfriend and Inaba boldly replies that he'd date her in a heartbeat if he got the chance. Though she's stunned by the confession, Ikumi can't find any reason to turn Inaba down... so why not? Things turn steamy fast, but they have to press pause to finish their work first, and the waiting is sweet agony...! Muscly macho man Inaba doesn't disappoint, either; once they're back at it, he has Ikumi cumming so much she can barely catch her breath. This office romance is hot, heavy, and non-stop!
