The scene involving the girl with the dog, the girl is at least 16 to 17 years old, which is legal in many states. You're using somebody who is under the age of 10, which makes it pedophilia, child molestation and child porn by description. Sex with the dog is bestiality, which to some is disturbing but others find it normal and even acceptable. Especially if somebody chooses to partake in such activity as a willing participant.
Secondly, In a situation like this RPG is set in, society's view on what are "men" and what are "women" depends on various views of when one can take on the responsibilities of an adult by a certain age. In the 1800s, that can be from 13 to 16 when a bay goes out to take an apprenticeship before taking on a job and a girl can be considered as marriageable which is usually by the start of her menstrual cycle. Thus, no cycle for a girl, she is still a child.
This is where I am bending the rule, though Hondo may want to not bend them: if a child can be considered as an adult due to their physical maturity and ability to take on responsibilities then by old world standards - they are an adult.
Macey is 12, right at the cusp of her starting her maturity but still acts like a girl, especially around Zoey because she did not have a childhood. Remember where she was raised up and seen all her life - a Whore House. Because f these things she thinks is normal, she's willing to take things to the next level with her caregiver because that is what she is believes is right. But, look at Fernando's actions - he's trying to teach her how things should be by unteaching her what she thinks is right as wrong. For him this will not be an easy process.
In the situation outside Macey's home, kids grow up fast in terms of sex and carnal knowledge. This is true for many ghetto raised kids who fall into gangs and other activities, where they have to do things for both respect and attention. Ike the Mike is around 17, and is leading a band of teen and preteen thugs of both male and females.
In the post, I state that he was 20, but he is a lot younger because living such a rough life one ages quicker by appearance. If he was an adult, he would have been on the highway riding his bike with his raider band instead of being on foot. The biggest hint to Ike the Mike's age was him calling to Fernando "Yo Mister" instead of "Yo" or "Hey you."
I'm not going to write anything for you. I'm letting you know that because you are using a child in a way some might find unacceptable, you need to watch what you post. If it crosses certain lines, then the post would be edited to remove the offending material or the post in question to be deleted. If Penny was older, like at Macey's age or older, I would not question it. But you are using a child. And time and time again you have stated that she is 9 years old and has undergone a procedure to stay at 9 no matter how many birthdays she may have which continually makes her a child. Plus Penny was not a willing participant, it is something that happened to her and she accepted as "normal." Understand that difference.
