FPRE-002 In order to protect her beloved boyfriend... A big-breasted part-time worker, Azu Amazuki, became a sex slave at the store manager's command and fell into orgasm through aphrodisiac creampie training. - Amatsuki Azu

Azu, who was working desperately at multiple part-time jobs to earn money for her beloved boyfriend's school fees, was tired and made repeated mistakes at work and was told that she would be fired. However, when she pleads with the store manager to make some extra money, she is given the condition that she performs sex work during the late-night shift. Azu tearfully accepts the unreasonable request, but it also inflames the senior clerk's lust... and her young body is relentlessly trained.
