Kanna and her adult son clash over everything, with every conversation turning into an argument. One day, a careless remark wounds him deeply and sends him into a rage. He takes revenge by overpowering her so she cannot escape, then subjects her to relentless forced orgasms that shatter her pride. By the time she regrets not apologizing, the choking, forced deep throat, fixed-vibrator torment, and pleasure-conditioning sex have already conquered her completely.
