Some more changes.

Realizing that the monster cock could be very painful and extremely unpleasant to have inside of him, he changed in a way that anyone with a pussy could take any cock regardless of size and shape without any problems. John also decided to change the relationship between himself and his two sisters. His older sister Erica, and his younger sister Melanie or Mel from short and himself had a incest relationship with each other since they were 18 years old. Ever since he turned 18 he and Erica would fuck one another and now that Mel had become 18 recently, she had joined their little fuck club too. Mel would be charged later as he wanted to focus on the pleasure in front of him. He also gave the same pregnancy protection to his sisters as he wanted to decide when they got pregnant.
