Young wife Hirono had no experience with men other than her husband. After her father-in-law discovered this, he cunningly trapped her and seized a decisive vulnerability. Manipulating her mind, he forced her into complete submission and indulged himself freely with her youthful body. Right beside her sleeping husband, he torments her most sensitive spots. Though she should feel disgusted, her body betrays her—she writhes her hips, craving more, displaying passionate reactions. Once caught by her father-in-law, she enters full combat mode. Her appearance becomes that of a beast stalking its prey.
