Just a hunch but I think 1 understands that.

Motivating OP to move out maybe?

They can't just be the mature adults they are supposed to be and talk to op?

They forgot they have a child.

They are just too busy making a new one.

Sad love songs would work, too.

Any music they really hate would work.

Or it could go horribly wrong..

Or you could make money with a porno... Just sayin'

fyl

Because that's really gonna help

Put on a cheerleading outfit and cheer them on!

This is sick indeed I'm not even joking. Should be also illegal since it's plain obscene, if the son is a minor it's even fucking worst. I wouldn't hesitate to got someone in a very shitty legal trouble for this kind of fucked up behavior.

Yeah but if it's your parents, you might just talk yourself and your younger siblings right into foster care. Damned if you do damned if you don't. FYL OP.

No, that's not my parents, I would have slammed the fucking door so hard they would have been scared shitless or at least in a very bad mood for proceeding in their disturbing show. I would have exposed them with the relatives, then talked about this with other people too and as last resort something like that. In any case it's totally fair for a kid to be preserved by mentally issued parents if shit gets very deep and even dangerous. In case the parents are just big idiots but not utterly insane, I think the threat to get in trouble should be enough to "convince" them to stop it and do their things privately as it's fucking expected from any decent parent.
