Chihiro, who runs a private tutoring school, could no longer endure her loneliness and secretly sought comfort in self-pleasure every night. One evening, she awoke to find herself surrounded by her students, who had taken photos of her in an embarrassing state. Blackmailed, Chihiro is forced to let the students toy with her mature fifty-year-old body, enduring two intense deep-throat facials. When the students turn their attention to her pussy, they subject her to relentless double vibrator torture, driving her into ecstasy. The brats' lust knows no bounds as they proceed to penetrate and rape her repeatedly. Losing all reason, Chihiro descends into a depraved female dog, begging, "Give me lots of sperm!" as she orgasms uncontrollably over and over again.
