We managed to get into a herbal specialty store in Tokyo that only a limited number of people can enter! Hazuki-chan is a super beautiful woman with a nice body who works there! What they sell is a magical herb... an instant stimulant that makes men erect! Hazuki-chan is a lewd slut who devours a dick that doesn't go limp no matter how many times it ejaculates thanks to the effects of the herb, and she milks it repeatedly! She mixes stimulant ingredients into lotion and oil for some extremely erotic, slippery play!
