Takuya and Mami have been married for eight years. They have loved and respected each other deeply since they began dating, but their sexual chemistry never aligned and intimacy slowly faded. Then Mami discovers that Takuya has been cheating through a dating site. Enraged and humiliated after trusting him completely, she transforms: she kisses him so fiercely it feels as if his tongue might be torn out, drains him with an unforgiving blowjob, and rides him with raw instinct until she cums herself. For the first time, his wife takes complete control of his orgasms and makes him her submissive pet.
