She doesnt care that he hears her moans of pleasure as he comes up the stairs to his marital bedroom. She barely acknowledges him as she sucks her sons cock. Ridding him in reverse she verbally humiliates her husband for being a weak man and makes him watch her pleasures that he could never give her. She tells him how worthless he is as she rides her son in various positions(virtual sex) and telling him how shes not letting him back in their bed but banishing him to the room down the hall so he can hear them overnight and be reminded of what he will never have again.
