Ena Satsuki plays an adult student who masturbates ten times a day and dates her boyfriend mainly for his huge cock. After gaining the magical ability to turn any man into a tireless piston machine with a glance, she searches for pleasure beyond masturbation. She devours her boyfriend with handjobs, blowjobs, titfucks, toys, and teasing, repeatedly restoring his erection until she can ride his big cock and make him unload. Still unsatisfied, she restrains a submissive man she met through an app, but her technique makes him cum before penetration. She then meets two older men in a hotel room and throws herself into a wild threesome, hoping they can finally satisfy her. Frequent facial close-ups make her aggressive seduction feel intensely personal.
