Amai Choubatsu: Watashi wa Kanshu Senyou Pet

Hina Saotome is framed for embezzlement and sent to Kokuyoku Prison while desperately insisting on her innocence. She soon discovers that she is the only woman among the inmates, yet the person who unsettles her most is Aki Myoujin, a strict warden who seems determined to subject her to intensely personal punishment for reasons she cannot understand. As Hina searches for a way to prove she never committed the crime, fear and attraction become tangled in her encounters with Aki. The more power he exerts over her, the harder it becomes to separate the authority forced upon her inside the prison from feelings she does not want to acknowledge.
