I think Pinescest was my first incest ship, but really it was those six bastard brothers from Osomatsu-San that got the ball rolling. That shit was formative to my love of incest and eventually abuse, noncon, etc. What's funny is I used to be so bothered by people shipping unhealthy/abusive ships when I was a teen lol, I wanted the characters to be happy. But over the years I've found the nuances of darker subjects are often more interesting to explore than the nuances of fluff. I'm not a fan of empty fluff, I like most when it's entwined with complexity :3
