This is so good. I like how much of a 'leader' Mrs Hag is. She's calm and knows what she is doing.
I respect how you have the balls to say that Andy is 7, none of that crap of being a legal adult or some lame excuse.
You have such nice taste in music, using Far Cry music was such a nice option! What an amazing game that was.
The sex parts feel more natural, compared to your past works this is more relaxing, great evolution!
But what I find the as most gorgeous thing is how you make incest hotter than Nemlei does. Instead of just making them have wild sex the moment they take off their swimsuits, they act natural and have cute siblings bonding, like playing in the sand or in the water. But, they are naked all the time! They even joke about it or ignore it. It's like they know the 'happy moment' is going to happen, but first they just want to have a more 'friendly' fun together while they teaste each other.
I really hope you can make more of stories of them with this behaviour of them being a caring family, but there is something going on, and it slowy builts into the sexual part. Here is an example of what I mean of what I'd to see: 
"Ashley is playing some videogames with Andy in the living room at home. Ashley is casually wearing a black underboob t-shirt, a white thong and a pair of black high socks. Andy on the other hand, is only wearing really big blue shirt that covers his body, white socks but no pants or underwear. Both don't care for what the other is wearing, they just want to be the winner. Sometimes Andy, as any kid would, cheats for some seconds by doing some things to his opponent; he pulls Ashley's thong in different directions, slap her semi-exposed breats or pull her nipples. On the other hand, Ashley just ignores him most of the time, but when she snaps she grabs his little brother's shirt and puts it on his head, exposing his little naked body. She then proceeds to grab him and sits him down on her legs. To make things worse (or better), she then starts playing with Andy's nipples and starts mockings him for getting an erection, which it's producing a lot of precum. She only lets him go if he apologies. He always complies. 
This happened so many times that night, that Ashley's legs are filled with his underaged brother's precum. The smell is driving her crazy, her pussy is so wet and her body full of sweat, she can barely touch the buttoms. She wants to ejaculate as soon as possible. But she must beat Andy first, to create an excuse to start hate(love)-fucking him."
Sorry for the schizo wirting, I have to admit I got horny from writing all of it.
Your work was a 10/10 reading btw, thanks for sharing with me. 
I hope you have a pleasent rest, see you tomorrow!
