Mami decides to resign from the company where she has worked for years in pursuit of career advancement. Her only regret is her unspoken feelings for her coworker Hajime. After her farewell party, the two end up alone together, and Mami boldly invites him back to her place. Hesitant at first, Hajime eventually enters Mami's home, and the two drink together, gazing deeply into each other's eyes. In that moment, their suppressed emotions explode into passionate kisses, leading to intense sex. Without protection, they engage in creampie after creampie, as Mami, barefaced and vulnerable, surrenders both her body and heart to Hajime. Over the next two days, they repeatedly crave each other, with Mami eagerly accepting his cum again and again, deepening their intimate bond.
