A memoir revisiting a middle-aged woman's obsession with masturbation. She candidly recounts how deeply immersed she's been in lewd pleasures from childhood into adulthood. Her sex life with her husband has grown dull and unsatisfying. Drawn to her robust father-in-law's virility, she's overwhelmed by irresistible urges. A married woman enjoying self-pleasure casts a heated gaze toward an electric jackhammer at a construction site, intensifying her own desires. A young woman writhes in boredom during her hospital stay, her fingers gently touching her lower body. The camera closes in with powerful, explicit angles on her slick, wet crotch.
