Rino is a temporary office lady with a voluptuous big-tits body and strangely seductive mannerisms that make her a daily target for sexual harassment by older male coworkers. While most women would be repulsed, Rino acts different—blushing yet appearing strangely pleased. In truth, she's a deep female masochist who gets off on being tied up and having an extra-thick vibrator rammed into her anus. This intense, compulsive pleasure deeply consumes her everyday life.
