私がこのように生まれたのか、それとも寝取られを選んだのか、その1

I really couldn't identify within myself if I happened to be born that way, or if I suddenly really chose to be a cuckold within my own home. When I married my current husband, I really didn't imagine that I would be jealous like this and I didn't even imagine that one day I would be a cuckold inside my own house because of his sister-in-law who is always here hitting on him shamelessly in front of me.
