I want to say you are full of chit, but I might get banned for saying this in a PG-13 rated forum, so I won't.

That's ok you people think its made up because it seems like so but it is true.
Since her mom strips at home with lingerie and mini skirts and watching porn, her mom has brought her stockings and garnter because she likes how nice they look.
And she does look very cute in them, I'm being straight out and saying yes Iam now just going with the flow.
She wanted me to take some pictures of her posing which I have and wants to look back on them and see how adorable she was.
Just can't load pictures here.

kids in lingerie are not 'adorable' they are sexualized for pervert men by other pervert men or women

she is FAMILY/A HELPLESS CHILD who should be able to count on her loved ones to protect her and keep her safe, not use her for their fantasies

and something is very wrong with the 'flow',,,

good lord, if the 'mom' next finds some drugs that make her 'happy' will she share and encourage their use with the child too?

children do not have the emotional development to do everything ADULTS do, thats why we call them children and adults,

I have watched the evolution of this topic without commenting.
This is a very disturbed family unit.
OP There are times when you contradict yourself. You do not have concern for your niece. You are seeking attention by something very twisted.
You first stated you are concerned about your niece and her mother is always busy.
It slowly came out that you, your brother's ex wife and a child are watching porn, masturbating and taking photos/vidoes.
What you are doibg is illegal. It is a form of child abuse.
It is also morally and ethically wrong.
You are contribuiting to stealing the innocence of a child.
What's next? You start pimping her out for financial gain?
If you truly have a concern about what's going on, you should report this to the authorities.
Oh wait you can't do that because you will also be taken.
This child, and any others does not belong in the home. She needs counseling and so do any participants who contribute to her current status.
