Ruka Mizusaki is a men’s spa therapist from Takaido with a boyfriend, a filthy body, and a tough delinquent attitude. She may be used to teasing and controlling customers at work, but a mature porn actor’s cock makes her scream through hypersensitive orgasms. Once penetrated, the supposedly cocky therapist is conquered by pleasure and becomes completely submissive, squirting wildly in her porn debut.
