Sex with someone with a familial relationship, but no blood relationship. Sometimes treated as incest in the law, but not as much of a taboo subject in common society.
"Dude, she's not my mom! She just married my father."
"So that's pseudo-incest. Still illegal in this state."
Caring for someone to the point of vulnerability knowingly your going to get hurt at some point by them yet still taking the chance to be connected and is something we should not jump into or let it happen lightly. Not necessarily a romantic sexual feeling
I care very deeply for you and believe we'll always be Emotionally connected.
I feel emotionally invested in your life
