Chitose, a young married woman with J-cup 110cm massive breasts, goes to a lingerie modeling agency with her husband. Her husband, a deadbeat only interested in money, allows not only lingerie modeling but also masturbation filming. While he waits outside the room, the agency staff gradually escalate physical contact. Though Chitose feels uncomfortable, she's too afraid to refuse and endures it—until she's finally forced into rough treatment. The next day, Chitose is called in alone as a lingerie model and subjected to bondage and sexual training. Initially resisting desperately, she gradually awakens to deep physical cravings, soon craving cock on her own and spewing out filthy, obscene words nonstop.
