ALDN-238 This bitch beast, Sumire Miyahara

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, Sumire desperately resisted with reason, but eventually, her instincts awoke, and she became a 'female' in front of her stepfather. However, her husband witnessed this scene. What action did the enraged husband take? And what was the outcome...?
