ALDN-252 This bitch beast Iori Ryoko

The stepfather was troubled... Why couldn't he have a precious heir?
One day, he accidentally witnessed his son and daughter-in-law having sex, and the stepfather became convinced. That's right... His son lacked 'manly' ability. The stepfather decided to impregnate her instead of his son. At first, Ryoko desperately resisted with reason...
But soon, her instincts awoke, and she became a 'female' in front of her stepfather. However, her husband caught sight of this. What action did the enraged husband take? A family that defies common sense is tightly bound by the bonds of 'female' and 'male' in this abnormal love story. What will be the outcome this time...?
