A beautiful young woman named Hikari Azusa visits an oil massage parlor for her boyfriend, but unbeknownst to her, it turns out to be a den of vice. As she lies there helplessly, the masseur feasts his eyes on her voluptuous breasts and begins to rub sensual oils all over them. He then slips something into her drink that causes her body to react strangely. Despite her protests, he continues to pleasure her until she reaches multiple orgasms, squirting copious amounts of milk onto him. Overwhelmed by lust and the effects of the drugs, she begs for more while grinding against him. The masseur takes advantage of this opportunity, penetrating her deeply and stimulating both her sensitive nipples and clitoris simultaneously. She cries out in ecstasy as they engage in a passionate love-making session filled with moans and groans.
