Jun Mizukawa, a housewife, visits an esthetic salon introduced by her husband as a reward to herself. However, it turns out to be a bad shop where middle-aged male therapists develop women's bodies and make them their prey. With the help of drugs, they encourage sweating with sticky and daring massages. Soon, Jun's sensitivity is stimulated, and she says "stop" with her mouth, but her body cannot resist pleasure and gradually becomes aroused. She convulses and has an orgasm, and she urinates and squirts several times with an Ahegasa face. Developed into a perverted body with all parts as a sexual organ, Jun, who hides from her husband, repeats this many times, immersing herself in sex therapy with exposed lust and spreads her legs loudly, becoming a lewd wife who squirts sea water.
