Mina has money and freedom, but her husband's distant work assignment leaves her painfully lonely. A female friend offers her a suspicious drug that makes masturbation feel a hundred times more intense, then lures her into a trap. What begins as “just once” becomes six months consumed by drug-fueled sex with countless strangers. Overwhelmed by pleasure far beyond anything her husband gave her, she pulls wild orgasm faces, arches violently, screams through barely conscious sex, and is driven over the edge 21 times. By the time her husband returns, the once-delicate wife has lost all restraint.
