Two bad boys who are curious about erotic things are fascinated by the big tits of their classmate's mother Ruri. The two of them start secretly filming in order to grasp Ruri's weakness. Two people who took a picture of Ruri giving a fellatio to a man at home threatened with the material and forced sex. Breast rubs, cunnilingus, blowjobs, electric massager attacks... The pranks of the two gradually escalate. Her blindfolded Ruri blows her son's cock and gets fucked. When I take off her blindfold, I am surprised to find out that the other person is her son. However, she accepts her son's cock because of her comfort. The busty wife's body is trampled by the gang rape that the man who was called and the two joined.
