While her husband was on a business trip, 'Rina' had no nightlife and her lower body was constantly aching. Unable to bear it anymore, she started an affair with her son's teacher. However, the scene was secretly filmed by her son's classmates, a bunch of delinquents, who then blackmailed her and raped her. Worse yet, they did it in front of her son. After that, the delinquents would sneak into her house, force her to masturbate, and attack her H-cup breasts and big ass with their 'milk guns'! As things escalated, the delinquents even involved her son in gang-raping 'Rina', indulging in taboo acts. However, 'Rina' would grind her hips against the delinquents' and her son's penises, cumming over and over again! "I'm sorry～!"
