Saya Kirijou has just graduated from college and is stepping into a world full of unknowns. Surrounded by older male supervisors who kindly guide her through every task, she gradually learns the ropes of her new job. To her, these older men feel almost like father figures. Their gentle, watchful presence during work hours only intensifies her growing excitement. Forced to assume awkward positions as part of monitoring procedures, she repeatedly finds herself in mixed-gender bathing situations with her superiors. Each encounter throws her mind into chaos, and seeing her boss naturally triggers arousal. Unable to resist during work hours, she increasingly loses control, touching his body and spiraling deeper into arousal. Before long, she's engaging in repeated sexual encounters on the job. After being filled with cum countless times, a dream begins to form—becoming the department chief's wife one day.
