This Picture has Aleu from Balto 2 Wolf Quest and Kodi from Balto 3 Wings of Change having a Valentine Kiss. As well Aleu and Kodi Parents are Balto and Jenna. Aleu is sister and Kodi is a brother. Yes, it's Incest. For some reason Balto Fandom, other people love the ideas of Kodi and Aleu are Romance Attracted/Having Incest Sex. 
Don't worry Balto Fandom have made Balto, Jenna, Aleu, Kodi Romance Attracted/Having Sex all together in Pictures, Flash Animation, Stories, etc. The Biggest and most Popular Balto Family Secret. The Secret is Balto Family inbreed with each other. I really don't think Balto, Jenna, Kodi, Aleu would do incest. It's not because I know their Personalities and have post Text Post about it, incest Couples, etc. It's just the ideas is freaking Insane and Crazy, really out of character, never thought that way about Kodi, Aleu, Balto, Jenna. I really hate being reminded this exists. I think Balto Fandom/other people made Kodi, Aleu, Balto, Jenna as horndogs in pure form. 
Something only for Inkbunny. This gives me the ideas to post my thoughts on Aleu X Kodi because of truly thing in Balto Fandom.
