SPRD-582 Shit Sitting Piston Lady Tsubaki Kato

Tsubaki Kato, a tight-fitting investigator, uses his body to interrogate a man who seems to be a member of a criminal organization he's been chasing. A man who couldn't stand the piston interrogation of Tsubaki, who has a strong sexual desire, dies at the end of the interrogation. Her endless physical investigation continues, using her own body to interrogate suspicious men one after another.
