A cheeky gal earns money for dates with Sukipi by dating her own sugar daddy. One day, her sugar daddy gives her an aphrodisiac and she learns the pleasure of drug-induced sex. At first, she starts doing it lightly, but soon she goes to her sugar daddy to get some, saying, "I want to use it for sex with Sukipi too." The sugar daddy makes her take an overdose of the strong aphrodisiac, and every day he trains her to enjoy drug-induced sex, putting her in a brain bug trip.
