A secret spy boasting K-cup breasts infiltrates an illegal pharmaceutical factory. However, after failing her mission, she is subjected to "pleasure training" as a test subject for a new drug. She is given a powerful aphrodisiac, and her enormous breasts are violently fondled as she is forced to experience a never-ending hell of orgasms. Her body repeatedly climaxes against her will, and as she is stained with saliva and love juices, her pride as a spy is completely destroyed. This is a full course of torture and sensuality, depicting how the aphrodisiac drives her sensitivity out of control with the massive weapon of her K-cup breasts.
