Mikako, who the father thought was his real daughter, was the child of an affair partner. The day he found out all about it, his love turned to hatred, and in his rage, he asked all the male relatives to rape her. "You're not my daughter anymore!" Mikako is passed around by her beloved relatives and raped until she is completely worn out. Continuous creampies, sobbing deep throating, and a brutal gangbang that doesn't end even if she cries and screams!!
