We managed to get into a herb specialty store in Tokyo that only a select few can enter! The super beautiful gal "Sarina" is a clerk there! What they sell is a magical herb... an aphrodisiac that instantly makes men erect! Sarina is a lewd slut who greedily devours a dick that doesn't go limp even after ejaculation, milking it repeatedly! She mixes aphrodisiac ingredients into lotion and oil for some slippery play!
