Now flip the genders so it's a well-endowed woman seducing a man away from a loveless marriage while at the same time teaching his kids self sufficiency so they can bang all da while the kids are away, and you've got a real winner of a story.

I' I don't know how to feel about this one. Its not really NTR, the kid actually ends up happy and is much better off, the father was never really in the story. She ends up happy as well.
... Happy ending I guess?

I hate that the best doujin artists ever, always. Make. NTR. The best artists always draw the most fucked up stories bro. Why can't we get a nice innocent story with literally goated art ????
