JUFE-502 Reina Momozono, a part-timer with huge breasts, becomes the store manager's sex slave

Reina, a part-time worker with huge breasts, works multiple jobs to pay her boyfriend's tuition, but fatigue causes mistakes and she faces firing. She pleads with the store manager, who offers sex work during the late-night shift as a condition. Reina tearfully accepts, which arouses the senior clerk, and she is trained relentlessly using her huge breasts.
