ALDN-326 This bitch beast, Reiko Kobayashi

My father -in -law was worried ... why can't we get an important trace?
At some point, he witnessed his son and wife's sex.
Yes ... my son is low as a "Han" ...
My father -in -law decides to seed it instead of his son.
At first, Reiko was desperately resisting her reason, but her instinct wakes up, and Reiko becomes a "female" in front of her father -in -law.
However, my husband is witnessed by her.
What is the behavior that the exciting husband took?
A common sense that the collapsed family is strongly connected by the bond between "females" and "Han".
What is the end of this time ...?
