Working at a real estate company, I was celebrating the end of the workday with my boss and senior colleague Tsubasa Hachino, drinking together in the office. In high spirits, the boss kept praising both me and Tsubasa while downing drinks, eventually passing out. Seizing the opportunity, the slightly tipsy Tsubasa moved closer to me, and despite the boss lying right beside us, straddled me and started getting intimate. She suddenly kissed me deeply, intertwining her tongue with mine, then stared intensely at my aroused crotch. She took me into her mouth with a blowjob before mounting me, riding me in the cowgirl position as she thrust her hips, her body trembling with pleasure. In the quiet office at night, with our superior unconscious beside us, we indulged in passionate creampie sex.
