Father fucks his daughter's slut thinking he penetrates his wife

His daughter's slut wants to fuck him because it is a vicious way out that incest doesn't worry him in the least. The mother is a whore too and agrees that her daughter will fuck the father, so they draw up a plan so that the man has no problem getting his cock in. What they do is cover their eyes so they think they are fucking the wife when they actually penetrate the daughter. A while later they tell him the truth and between them they eat his cock to get all the milk.
