Chitose's affair with her school teacher is secretly filmed by some bad boys who are her son's classmates, and they use the footage to rape her. Right in front of her son. The bad boys get carried away and attack Chitose while she is masturbating in the bathroom, firing their milk guns at her big tits and ass, forcing her to masturbate. The bad boys escalate even further, and involve her son in a gangbang creampie sex session. She is also continuously injected with semen. Both Chitose and Ko are so sensitive to the dick that their huge tits shake and cum over and over again!
