Rinko, your friend's mother, is strong-willed and scary when angry, but she also dotes on you as if you were her own child. Overwhelmed by her voluptuous body, you succumb to temptation and sneak into her bedroom, indulging in masturbation with stolen underwear. However, your sinful act is discovered by Rinko herself. Expecting to be scolded and despised, you are instead met with awe as she is mesmerized by your well-endowed manhood. Witnessing her transformation from a strong-willed woman to a submissive and vulnerable creature ignites your primal instincts. You seize the opportunity and ravage her mature, busty body, reducing her to nothing more than your personal pleasure object. You continue to engage in perverse acts with Rinko, fulfilling your darkest fantasies while keeping it hidden from your friend and her husband. You relish in the overwhelming pleasure of dominating and corrupting your desired friend's mother, turning her into a willing participant in your depraved acts. [Translated from DLsite]
