Amai Choubatsu - Watashi Wa Kanshu Senyou Pet - Episode 12

The story unfolds in a prison in the near future. The work revolves around Hina Saotome, who is trapped despite her innocence, and the elegant and sadistic guard Aki Myojin. The heart and body of Hina are at the mercy of Myojin's "cruel and sweet domination," ranging from physical examinations to visits to her lover's prisons. The subtitle of the original manga is translated as "I am the guardian's private mascot".
