I want to curse at my step-mom.
Why do you want to cuss at your stepmother? Did she do something?
Because she could get pregnant and then I'll get fucked again.
It's not okay to swear at your step-parents. Maybe you can complain about her pregnancy to a friend? Your stepmother might be hurt by your judgement on her pregnancy.
I don't care if she's hurt.
It is wrong to call her bad names and make her feel bad. She is an adult and if she wants to have another baby it is her choice. You should respect your parents, you might enjoy having a sibling.
