Stepmom organizing taboo POV 3some with kinky stepdaughter

Babe, she's not related to us and she's a grown woman.

I mean, I know she's adopted, but still it's not appropriate, I don't think, is it?

I mean, I feel like she's practically inviting me in there.

Well, I mean, you're the mom. I guess she knows best. I'm just not sure.

I do know best, and that's why I have another good idea.
