Rui is a drug investigator and discovered the pusher's hideout with her coworker guy. When they got there to arrest pushers, they were captured unexpectedly, and she slept with one of them to escape from there. Then she visited the hideout again to save her coworker, but she failed it and was made to be a sex doll for the pushers; they gave her various drugs and practiced her sensually. She's made to achieve orgasms repeatedly until she's almost passed out and fucked roughly and aggressively, which makes her get crazy yet horny too.
