Newcomer voice actress Kurumi Tachibana is called into the studio for a game production job. Due to her earnest and honest nature, she endures sexually harassing behavior, gradually being drawn into compromising situations. Under the guise of performance coaching, she's repeatedly touched all over, and accidentally lets out moans when fingers reach sensitive areas. Eventually, an erect penis is forcibly inserted, and she can't hold back, reaching a powerful orgasm. As a result, her hidden masochistic nature is exposed, pulling her deeper into increasingly lewd acts.
