Indeed. Jada craves affection and love. She is
starved of affection. Her overworked mother didn't give her much, neither did mother's boyfriends. She's probably trying to get it where she can. And sex is a way to get it. A quick and easy way to get her fix. Because holding hands and head pats aren't enough. She needs
more. She doesn't rely on people to give her any love so to get her fix of feelings in a short amount time they need to be more intense.
With the mc she found someone who actually
cares about her. So she is teasing them about treating her like a parent. But in fact she enjoys it. That's why she suggested her calling the mc mommy / daddy. But she should tone it down.

Adding during sex to every sentence
mommy is overdoing it.

Not that it doesn't turn me on.

I think she needs to learn restraint. Her hot head has already caused her trouble. She doesn't always need to prove something to someone. Maybe in a secure relationship she can calm down. She could even help Rachel get some of her confidence back. As the mc asked Rachel, if it doesn't make her feel good that a younger woman admires her.

She agreed in a way. Jada finds Rachel attractive. But probably more than that, she likely sees her as a potential "parent figure" .

She asks the mc whether they are attracted to Rachel and seeing that to be the case she pushes the mc towards making it real. But she shouldn't act on her own. She should consult with the mc. After all this is the mc's house and the mc's (step) mother!

I'm afraid Jada will mess things up if left unchecked.

After a happy "family reunion" they all can screw as much as they want.
In fact Jada can do more than that. She can help Rachel and Ellie reconcile.

Jada and the mc need to coordinate their efforts to bring the family back together.
